Need motor help for turbo

[jdmeg6]

Right now I have a '95 Si HB and want to stick with the single cam route. Not sure what the engine code is right now but I know I want to stick with vtec. I have like 100k on this motor and want turbo so I am gonna put a new lower mileage motor in. What do u guys recommend for a setup. Any help would be greatly appreciated. Also, if anyone is from San Diego and would like to help, just send me an email. Thanks.

:shock:

It depends on what kind of numbers you are wanting to get, in ET and whp/wtq...

I'd go with a D16Y8. A perfect starter turbo kit would be the apexi kit if you can find one. They are discontinued now. I find the Greddy 15g kit to be decent, but for some real numbers (250whp+) you are going to want something bigger, and a built motor.

Thanks for the help. I have a 95 si, that has the z6 in it right? I kinda dont want to change my motor if i dont have too. It has 90k on it buy i am planning on building the whole thing. Will it be ok? Also, do your have and ideas where i can find a apexi kit for sale? thanks for everything.

uhhh if you tear the motor apart and rebuild, clean, port , and totally re-do the motor, then go for it ... but you could probally find a newer d16y8 at a junkyard for less than what it would cost you to rebuild you old zc ... im not saying you cant do it , but .. it might be $$ costly $$ ... and if u want big turbo just get a hybrid t3/t04e turbo .... those are pretty effectife for high hp gains .. but i dont know if u could put that on a d16y8 on stock internals ... might have to build up the block a bit to handle that big turbo

That motor is fine. 90-100,000 miles is nothing. Tuning is key. You could keep the STOCK Z6 in there and spend your money wisely and have a reliable motor. I wouldn't have any problem at all feeding a stock Z6 10-12 psi on a normal sized T3 with decent tuning. If you plan on 250-300whp as a daily driver, I would suggest beefing up the internals, but anything less is a waste. I know of so many people boosting 10psi+ on STOCK motors with 100,000-250,000+ miles. Stock motors will take more than you think. I boosted the hell out of a D15B7 and to this day it's still running, just not in my car. :P For the last 300-600 miles I was boosting 14psi with a blown head gasket like I stole the ride. 8)

Don't underestimate the stock internals of the mighty D

i love hearing stuff like that ... dr.boost , u make me smile with talks of 10psi on stock motors !! yay !!

[Dr.Boost]

Haha, I remember when I was first thinking about boosting a motor. People told me it would blow on the first rev and it won't last more than a few rides and blah blah blah.... Obviously none of them knew what the hell they were talking about. Not only did it not blow on the first rev, it's still breathing to this day. I boosted the hell out of it. I swore it would never blow. The only downfall was that damn blockguard. If it weren't for that stupid little piece of aluminum I would still be rocking that motor. I bet it would still be running on 14psi to this day.

I rememebr when I put that blockguard in too. I hadn't even started it up yet and I talked to a guy that had bad experienses with them before and he told me to tear the head off and take the blockguard out. I didn't listen to him(of course)and I fired that bitch up and romped the hell out of it. I sure do wish I would have listened to him. :roll:

THanks again guys for all your help. If you were gonna start building your motor for boost what would be the first thing you would do. My friend told me a wise investment would be some valves and valve springs so the valves dont float (i think that is how he put it) due to the high rpm of a turbo motor, is this true?

dr.boost ... what happened to that motor? u blew it ? what was wrong with the blockguard? is it not good to use those?

Uh..adding boost doesn't mean you can spin your motor to 12,000RPM. Your rev limit doesn't change. The first things to build would be the pistons and rods.


thesqad127: The damn motor kept overheating and it took me a while to realize it was the blockguard causing it. It ended up warping the cylinders which was causing a coolant leak into the #1 cylinder. I wouldn't EVER use a blockguard again. If you are stuck on the idea of using one, DO IT RIGHT. Have it professionaly installed(trim to fit, welded, honed) and make sure the passages are big enough to flow enough coolant. The one I bought was shitty and had very small holes. I tried to drill them out, but it didn't fix my overheating problem. :cry:

damnnn that sucks ... i dont plan on using a blockguard, oddly enough ive heard nothing but horror stories from people who have used them ...

im having an overheating problem with my d17a2. it turbocharged nothing is done to the internals im running 7psi 11 with boost creep. what could be causing it to overheat.
