Hi im doing a 2 part d16y8 project. First im building the motor up strong enough to handle up to 300whp with a turbo, once its built i will drop it in and start gathering parts for the second part which is full turbo kit. I've almost got all the parts i need for the motor build and heres a list of everything im doing and anyone with experiance can tell me if im missing anything or what they think about the build. So here it is...

All this is going to be going into my 1999 black coupe

<U>bottom end</U>
stock crank
eagle h-beam rods
cp 9:1 pistons .020 over
ACL main/rod bearings, thrust washers
block bore .020 over
hi-flow waterpump

<U>Head</U>
Port & polish
valve job
ported Y8 intake mani.
ARP headstuds

new timing belt
new head gasket
All new gaskets and seals
P28 ECU w/obd1 conversion harness
knology Hot Wires
3 Bar Map
fidenza Flywheel
race clutch

thats all I can remember for now lol if i remember anything I forgot ill add it in.

I'd recommend getting an ACT stage 2 clutch and a new heavy flywheel, paired with Quaife (or the newest OBX) L.S.D. You should also buy a new oil pump and have it bored out -- the d16y8 oil pumps suck ***. Check the head and make sure it's balanced, put in ARP headstuds and a new head gasket (OEM only). Oops, you already have that there, my bad.


You'll need set of BF Goodrich tires to boot also, you'll want the best tires to get adequate traction.. Um, that's all I can think of now.

As for the turbo manifold -- I'd get either a log manifold (reliable and quick to spool) or a ramhorn (really bitchin' to look at and have great power potential -- reliable also but a bit more $$)...

I'd definately get a medium sized t3/t4 turbo (EXTERNAL WASTEGATE!) to make your horsepower goals, along with a test pipe and a 3 inch exhaust from the downpipe back.

Oh, and you definately need like 2 or 3 step colder spark plugs - I didn't see that on your list.

 

Doing a similar build! My first ever...

In for info and advice!
