I'm having some issues with my SR20DET and I was wondering if anyone could help get me going in the right direction to solve them. I have very low miles on my engine set-up approx 7,000 at last count and it smokes under hard acceleration. Its hard to tell in the rear view but it appears to be blueish, oil smoke. I've done a basic compression check and they were all within about 3% with the high 2 right at 160psi. The plugs are pretty fouled, dry black. While doing the compression test I could smell fuel even though I unplugged the injectors. Hot start can also sometimes be more difficult, it can take a few tries or just have to crank a lot longer than cold.
Also another issue, maybe unrelated, maybe not. At a recent autocross I've learned that my engine responds a lot like a light switch, off or on with very little in between. It bucks a lot at higher rpm part throttle. Doesn't seem right but is that to be expected with my set-up?
Also, the car sits a lot, the mileage has accumulated over about 5 years, and I'm running high boost (18psi) so I'm really not ruling out any wear items just due to mileage.
My set-up is:
built block and head
replaced valve guides and seals on build
cometic mls headgasket w/ARP studs torqued to recommended torque.
disco potato turbo (GT28RS, GT2860RS)
ebay exhaust mani
JWT ecu reflash
msd 50lb injectors, top feed
cobra maf
open bov
Any help will be appreciated, thanks in advance.
