boostzealot's 3.5L...if you dare

[SPD_FRK]

im going to install the ported and polished 74 heads first, see how it goes and then possibly end up with some ported 75 heads, building the headers, installing the 75 crank and decking the pistons to a 0cc flattop. again this should make for a 14:1 CR motor with the 74 heads on because of the small combustion chambers. ill be running a water/meth injection setup and possibly going E85 with some STi pink injectors for street duty. track duty injectors will depend on how my duty cycles look at peak torque and how they look at the top of the rpm band. ill also be moving up my rev limit to 8k to take advantage of the intake flow characteristics and the heads.

I have been talking to him off and on the past couple months about his build, finally getting to see some progress with it now. You thought his machine was a beast before, all of this is going to unleash even more from the 74 builds.

[m-rod]

Nice! This is going to be awesome. Also, does he plan on ever signing up here?

[SPD_FRK]

Nice! This is going to be awesome. Also, does he plan on ever signing up here?

Yea, he already has pushed the 3.5 to new limits, this one is going to go above and beyond those lol.

I sent him a message on C3g telling him to hook up with us over here and that you are starting your 3.5 build...hopefully he joins us here.

Yeah no doubt. 14:1 compression?!!?

I hope so, that would be great to have him on board.

[beam514]

holy hell 14:1???

I hope he comes over here lol. I'm not a big fan of Club3G

[4-G-rim]

That would be nice to have BJ on these boards since he is probably the guy to talk to when it comes to swapping a 6G74 into a 8g and sounds like he is making more progress to reach new limits. I have talked to him on EvoM a few months ago.

[beam514]

he is probably the guy to talk to when it comes to swapping a 6G74 into a 8g

ouch!!! lol jk BJ is extremelyyyyyyy knowledgeable on the subject haha

[SPD_FRK]

I am interested to see how his tuning goes with that high of compression. I know the S2000s run like a 12:1, and once you get into that higher CR range tuning and fuel are critical factors in something like this. I knwo the last time I talked to BJ about his build the 12:1 was pushing it because the tune has to be pretty much to the "T" and fuel choices become limited (Ie why he will have to run E85 on something like this).

I don't know near as much as Bj does, but if I don't know I hit him up for the answers lol. Hopefully he will stop by and check us out atleast and see that others want him here as much as I do.

[ivory8g]

wow his plans sounds like they changed a little since i last talked to him. i wonder what he is planning to use to tune that CR? aem standalone perhaps.

[m-rod]

Wasn't he even talking about turbo recently? I'm guessing he ditched that idea for the much higher compression ratio.

[SPD_FRK]

Wasn't he even talking about turbo recently? I'm guessing he ditched that idea for the much higher compression ratio.

He still plans to do a turbo setup from last I heard. He is just wanting to document everything thoroughly on the 3.5L platform so people know what tey can do with one.

[boostzealot]

WOW matt you HAVE outdone yourself here yet again. thank you so much for not only the kind words but the hook up on yet another great opportunity to share info with you guys. hey everyone. im glad to be so well received as always. and again everything everything everything will be documented. just wait until i get back from vacation so i can take pics of the motor and its progress along with the engine harness im redoing, the water/meth setup, the new bigger injectors and the fact that it will all be tuned off of something streetable and easy to tune. im officially going with the 01 ecu and greddy emanage ultimate for tuning purposes. i still just cant see spending the money on an EMS when i can place that money elsewhere and get the desired outcome with the EMU. i have seen the EMU do some pretty impressive things concerning tuning and getting a difficult setup to work properly while maintaining driveability. not to mention being able to aid the EMU with an 01 ecu and open source is also a testiment to its streetability. not to mention, if i go too much to the race car side ill be slammed into a class of car that sees the likes of porsche gt2's, Z06's, and track prepped STi's and EVO's. i still need to stop being scared and buck down and buy a LSD because this is going to be one harsh bastard on one particular wheel. lol. thanks guys for the interest and im trying my damnedest to hurry up with this so that things can get documented and put out to you guys.





oh and im still going boosted later, twin EVO 3 16g setup with 75 non mivec heads done about like these 74 ones are. it will be my front wheel drive version of the mine's R34 GTR-----response machine. (10:1 CR, 75 crank, p&p 75 heads, my crazy intake manifold, and maybe finally some 272's)

[SPD_FRK]

I saw an opportunity to build a community for us based on performance man, a few of us have picked up a lot from what information was left behind...and just picking pieces up as I go along on other forums. You pretty much are the *th Gen Galant platform's R&D guy IMHO. If these guys had questions I didn't know I was going to you for the answer...I think we need a "GT Certified Tech" patch for you

I wasn't sure if you would go full standalone or not, but its hard to tell sometimes you know lol. You will definitely have to make a thread detailing some more information on the 01 ECU stuff, I am really interested in learning more about that stuff. I have the 99 ECU, and have looked into the ECU swap stuff over on C3g, but hard to draw out the valuable information from the junk in that thread. I am going to run the Greddy Ultimate on my setup as well, so to know you are sticking with it this far on your own buld leaves me assured it will do the job easily for me too.

I can already tell a lot of people's eye's popped a bit with that last tidbit of information, high CR turbo build... There was a build thread on TGC that got debated pretty heavily about this configuration...not too many are up to speed with that stuff yet. I will let you spill the beans on why you are choosing that CR for a turbo build, I just hope to get a ride in the N/a Beast before it gets boosted!

[boostzealot]

yeah man i think you did a good thing here. i hope it doesnt get cluttered with drama and useless banter like the "other" site. lol i like tgc really. its been around for forever, its just some of the people there arent focused on performance and i stuck out like a sore thumb in some cases. im glad to be on GT though and that patch would be the shit!

as far as engine management goes, the emanage is really a pretty versitile tool. it can do a lot and monitor even more. when you begin giving it more to do, it has other harnesses you can add to help it out. for being close to being boosted, you may want to go ahead and acquire an 01 ecu. this will help you scale the injectors, log water temps, knock, injector duty cycle and a few other things.....but be able to do something about it if you dont like what the logs say. ill put up more info as i go about the ecu swap info and so on. ill also start playing with it myself after all my job training is done.

lol yeah i will definately have to take a ride up to colorado to come see you and marc before i boost it. it really depends on how much fun i have with the new NA build. if its as much fun as the last one without any headaches then it'll be a much longer time before i go boosted. but if its a hassle trying to wrangle that CR then ill go boost sooner. from the guy's perspective who is doing the heads and intake manifolds along with the other details of the build, he is convinced that the motor will have the potential to make 400 bhp which will translate loosely into....you ready?....370whp! NA! in a 2880lb car!....lol its laughable right now because we all saw how fast the car was before with only 230whp so....

[SPD_FRK]

Be assured we aren't going to bash the "other" site on here, nor tolerate any of the same/similar drama to occur on our site. If you browse around the site you will begin to see we are taking this community seriously making sure this is not just a forum based website...lost of good content and features here, and plenty more to be added. We aren't just performance here, but it is our main focus...having members like yourself in this community really builds the reputation for this platform's performance.

I really wish I knew about the 01 ECU stuff before I bought the second 99 ECU . I guess I can always sell that one anyways and pick up the 01, I assume there is some wiring changes on the ECU connectors also though correct? I really do like the appeal of the 01 ECU with being able to scale the injectors and all the logging ability. I would really hope the new N/a route works out, it will really take the 3.5 platform above and beyond what has been done already as most seem to build it for boost of just a lightly modified N/a engine. The Hp estimates sound pretty good, considering the cars you pulled on before this configuraton will rival some great competition. Were you running Stage 2 or 3 cams with the new build?

[boostzealot]

sounds really really positive and im truly glad to be a part of it.

i would sell the 99 ecu personally. its not that the ecu is bad its just not capable of being flashed like the 01+ ecu's. its the processor in the 01 ecu's that makes the flash possible. get ahold of a tactrix cable and an 01 ecu and you will be good for basic tuning and refining.

yeah i hope that the stroke wont hamper anything. before i had the pistons decked to 0cc my eyes got as big as saucers when i put a piston and rod combo on the 75 crank and rotated it just to see where everything was going to line up. omg. it was seriously like a good 3mm+ of deck clearance! and with no valve reliefs on the pistons i really had no choice other than to deck them. i could have left them and spent the money on getting a set of 75 heads but that wouldnt have been much fun now would it? lol. wish me luck. now im just saving up again to get it all back and in my garage so i can start building it.

[SPD_FRK]

We are all just excited you finally joined us LOL

I will have to post that thing up for sale then, no point in having two useless ones really. I can keep the one for a backup for those "in case" times. Not sure what the OE deck height is, but it definitely sounds like a really tight tolerance with the valve lift specs. Hey, if you are wanting to pick up a set of 75 heads for cheap let me know, I found a full 6g75 on car-part.com for $350. They are selling as core with good top. They wouldn't really devulge any more low end information other than the engine as smashed from the bottom (possibly just oil pan smashed, but not sure about crank). It would be a cheap set of 75 heads and other misc parts possibly though.

I get the saving portion man, selling some parts so i can buy better and more important ones...and money doesn't come in nearly as fast as it gets spent with bills

[ivory8g]

*claps for Bj*
What up bro?

And Matt wtf $350? that is awesome! i want to be there for the checking out/ picking up

[boostzealot]

thanks again for inviting me matt.

as far as the deck height for the 74/75 its 218mm. thats enough to go big on the stroke and not really have to worry about the timing issues until you get past 15*, well me anyways. i found out that this motor does just what its supposed to do when the timing belt lets go. the valves shut and dont damage the pistons or the valves. so timing issues and worrying about bending valves even on the stock clearances simply comes down to whether your timing is off or not. so i think i will be ok as far as piston to valve clearances as long as my timing doesnt slip or i dont advance or retard it too much to achieve a certain powerband. i will definately have to take pics of the process along with the clay measurements when i go to put it all together. but if you want we could go half on the motor so i could get the heads or you could let me know how much you want for them. i am leaning more to just purchasing a set just in case this motor is all about wanting to tear something (itself) apart everytime i start it.

marc, thanks man. i cant wait to see what mine will do to the streets of utah once done. it hurt some feelings last time and is surely to crush ego's this time around as well.

[SPD_FRK]

Those clay measurements will be good to see, I know when I built my HD I had to do that and it is really cool and "precise" so you knwo what your valve-piston clearances are. I remember from C3g you upgraded the valvtrain too right? Any idea what the stock valve spring rates were by chance? I t would be interesting to compare that to the RPW specs.

Well I was looking to buy a whole engine and came across that one cheap so I had to call the place on it. It was a place down in TX so it would have to be shipped. I have another 75 in CA, and IN that I have calls out to so I can ensure getting a complete good engine. I just figured for the price of that one for $350 I would toss that out there since the heads alone could resale for that amount I would guess.

[4-G-rim]

Be assured that GT will be structured and drama free. We are truly dedicated on having a board that Galant enthusiast can share info and learn from each other like any board should be. The staff all agree on this...and we all work together.

Since the excitement of having BJ on these boards have been overwhelming and a a great start to the 2010 year ....lets get this back on topic on some 3.5L goodness.

[boostzealot]

alright everyone i got most of the stuff back from the machine shop!!!! omg this whole build has me in shambles because i cant figure out how to calm myself. lol here's what i picked up:
block
crank
piston rings
bearings
flywheel
crank pulley
3 pistons
3 rods

now the only reason i have half of the piston and rods is because i havent finished paying for everything just yet but my machinist is a cool ass dude and let me take all this so that i have something to do until i have the rest of the money! tomorrow ill be throwing most of the bottom end together and measuring the deck height i have along with all the rest of the measurements we all will need to know when installing a 75 crank in a 74 block!!!! pics galore tomorrow. i have one busy day ahead of me.

[SPD_FRK]

SWEET! Hope everything goes smoothly for you man, I am really excited to see the pics of everything

[ivory8g]

i cant wait for pics Bj!!

[boostzealot]

ok so my plans went south when the errands i had to run in the morning took longer than expected and i ended up having to leave the shop early. so effectively i only had 2hrs to work on the motor today. at least i got somethings done still. all main bearings are installed and lubed, all main studs are in, crank and thrust washers are in, girdle is on and snugged down and 1 piston/rod combo is on the crank for measuring purposes.
here's what i found out. my complete deck clearance with the 3sx big bore head gasket will only be 0.795mm! still less than a mm so i should have a buffer zone for some timing advance or retard. wont be much though. tomorrow or tuesday ill be taking the pistons down to a local coater to have an anti-friction coating put on the skirts and a heat treatment done on the crowns. the heads are still coming along nicely and should be done by the end of the week. just waiting on some more tooling to come in. once they are done, ill take them over to the machine shop and have them clean the heads really well. enjoy the little bit of pics i have. (had to borrow a cam because i spaced and forgot mine in my haste/excitement to get to the shop)

[boostzealot]

i took a shit load more but my friend didnt send them all to me. these were the ones he sent me so...but ill have more in a couple of days. i love how sinister a block with a four bolt main looks with studs in the mains

[ivory8g]

i just felt something move in my pants!

bj....you're out doing yourself again and again. i am so inspired right now!

[m-rod]

Very nice. You are tempting me to get studs for my mains.

[SPD_FRK]

That looks pretty good man, I saw that guy on C3g was asking about rod stretch...not sure I really understood what he meant though? From what I can see of the cylinder bores though they definitely have an excellent cross-hatching in there now.

[4g63lover]

I just came BJ.
