I'm going to build my spare d16, i was running the gredy 50 state legal kit on it and the motor just wouldn't pass smog anyonemore so I rebuilt my other engine i had lying around. But I want to build the other one for some pretty crazy boost and power. My goal is around 350 hp. Does anyone have any experience with building the d16z6? I want to do porting and polishing but how much is that going to improve a turboed motor. I already have greddy e-manage but want to buy an AEM ecu system that can plug into a laptop so you can tune it. Are there any websites out there that anyone knows of that can direct me as to what parts and who to buy from??

 

why dont u do a little search... there are pleanty of d16 builds around....
have you looked into vitara,tt rods setup good for 400 whp

 

I did mine. Using stock bore and I did not sleeve tha block.

Used eagle rods w/ Nippon 8.5cr pistons.
DSM 450cc injectors (limited my hp to around 280)
Revhard cast iron manifold
T3 57trim turbo (50ar cold 63ar Hot)
ARP Head studs
External ebay wastegate (worked fine)
Uberdata tuned (Using this you can also plug a laptop into the ecu)
Fidanza 7lb flywheel (I dont recommend this for boost, adds turbo lag)
XTD 6-puck double sprung clutch
Twin Greddy type RS Bovs (Better to have two for high boost) so you dont blow pipes off as much. plus sounds/looks cool
I used stock cam/crank but I did not have high hp goals, just fast and fun.

thats most of it. but should be enough to get you started.

 

if you want to go the budget route vitara pistons (YCP) and tuner toys rods tune with crome. otherwise weisco pistons and eagle rods. whatever you go with I suggest having it bored over a little to clean up the cylinders(I hear 75.5 vitaras are available now) ARP head bolts are a must and an OEM or cometic head gasket will do the trick. OEM bearings are best but a lot of people are running ACL and others. P&P on the head would help but honda heads are pretty good to start with. It shouldn't be a problem to hit 300hp on 93octane @15-16psi* and 400hp on C16 @25-26psi* Search around there are a few people on HAN with D16 builds and turbod16.com has a wealth of info on d-series motors.




*psi and hp numbers are strictly an estimate based on what others are running actual results are dependent on turbo size and proper tuning

 

do a search under my name, you can find the details to the build in my old del sol that made 415hp and 387 tq

 

aem is good stuff.. but it's extreamly over priced when there are other solutions that will handle what you want to accomplish. You might want to study up before you go spending that kinda cash.
