Question, does that intake manifold bolt right on or do you have to modify it in anyway? Nice build by the way!

You didn't pull that head off at all for hot tank and decking? Did you install headstuds?

Personally, your goal of 400-450 is attainable on a stock bottom end, however I question that you didn't replace the headgasket (I prefer stock and headstuds, but general concensus seems to always be metal HG) and use ARP headstuds.

For that T3/T4 to make power, you're going to have some good pressure in the combustion chamber, so I would prefer a better clamping mechanism than old, stretched headbolts

I also hope that your tune is being done on a dyno by enthalpy. 400-450 is the upper limit of the stock block, but to effectively squeeze that much power out of the stock hardware, I highly suggest having your ROM tuner specially tune it on a dyno.

I tend to err on the side of safety, especially when a $1500 piece of metal is on the line. But good luck on the build.

I totally agree with you hijacker i know i shoulda taken the head off and changed the headgaskit. I thought about it alot but wht made me decide not towas the fact that i new its a healthy motor before the build. I drove the SR with bolt ons and a fmic at 12lb of boost on the stock T25 and it all held just fine plus its never overheated i never had one problem with this motor, so i know its a still a good engine thats kinda why i left the stock headgaskit on it. Once i get ready to build the bottom end im definatly buying an Apexi metal head gaskit and ARP headstuds no doubt.

I allready have my ECU tuned by R.S. Enthalpy and its plug and play now. I dont think ill be seeing power close up to 450 on the stock bottom end for me i just want to atleast hit 400WHP. When i talked to Chris and Scott from Enthalpy they rerecomend that i run pump gas 93octane at 12-14psi on the street then on the track anything above 18 to 20psi I HAVE to run the higher octane as of ''race gas''. Also scott said that with my setup i should close to high 300hp to low 400hp and that will satisfy me plenty.

Not for long if you're pushing that much power out of the motor. ~400whp on stock HG? 12-14psi on the T3/T4E is not the same as 12 psi out of the T25. If you can afford all the Peak boost stuff and to do this build, then you should be able to go ahead replace the HG and install ARP hardware. Blow the HG at full boost at the track, coolant and oil mix and bottom end is destroyed causing more damage and a more expensive rebuild than if you had installed a metal HG and ARP stuff. My .02, but anyway, nice looking build. Is your entire car seam welded btw?

Yes i know that. 12-14 psi is different from a t25 to a T3T4.

i really would like to put a metal headgaskit on itand some ARP head studs right know if i can but i got a layoff of my job so i have like no money right know

And then im gonna have to take the head to get it decked where il also have to get the block decked so then i would have to take out all the rods and pistons and everything from the bottom end im just not ready tobuild the bottom end though if i could just take the head off and put the headgaskit on that would make it even better but i know i cant do that with out the head beiing decked first.

well its ok

sounds swett idaho i cant wait man what lsd are thinkg of i went with the kaaZ 2 way.

i am plaing on a KAAZ 1.5 way lsd

you might not have to deck your head or block.

mine were perfectly straight so there was no need to. i still had the head put through a parts washer.

when i cleaned my stock hg off the block i used sand paper and a vaccum cleaner. so nothing got into the coolant or oil holes

is that really safe though i just need to make sure that none gets into the coolant and oil holes. so then i can just put a paper towel in each hole and just be really careful right

Yeah i think the 1.5 KaaZ is also really good i just havent felt what its like.

so i was thinking For my apexi head gaskit which is 200$ should i get the 86mm piston 0.8mm or the 1.1mm i want boost but im not really sure whats the best size to get right now. And my alternate headgaskit would be a cometic i can get one for like 90$ on ebay and the ARP head studs for like 130$

so i could be best with Apexi 1.1mm and ARPstuds for 290$

Then theirs cometic and ARP for 220$

what do you think

MY hg came off with the head. so there wasnt much on the block left to scrap off. i used a peice of plastic likea credit card or id. that isharpened on a sander and scrapped as much as i could with that. and then sanded it. you jsut have to be really careful. when doing it around the holes.

as far as a head gasket i have a apexi 1.1 mm 86mm piston.they were out of the stock thickness. when i ordered.with the turbo you are running i would get the 1.1mm head gasketi am only running a ..64 gt2871. and that is what i got.

make sure you get soem copper spray-a-gasket and coat both sides of the gasket with it

im gonna get the apexi 1.1mm with the ARP studs thanks for your help

so what is this copper spray-a-gasket tell me more about so i know what to do with it and were can i get it?
