well, i got my car turbo'd and running. i mean "running". i still need a clutch, my ecu chipped, injectors, pistons, block work/headwork, andi don't have the cash. so i chose to apply for a loan. i was gonna take out a $3000 loan to finish it... but last night i stumbled into a hell of a deal.

the guy i live with went to lincoln tech. his room mate is asking $2000 for his motor he pulled from his sol. so, i'm gonna take out about $2500, buy that motor, thicker head gasket for boost, a boost controller (not cheap out), external wastegate, and better BOV.

THE MOTOR:

Venom Intake manifold, venom injectors, AEM fuel rail with fuel pressure regulator.

y8 head, port matched & polished. .460 cam (crower or skunk2), fererra valves, skunk2 valve springs.

z6 block, bored .30 over. unsure of which pistons... but 11:1 compession. block is sleeved & filled. eagle rods, crower stroker crank.

si tranny, upgraded rings & synchros. stage 2 clutch. stage 2 axels

chipped ecu.

entire wiring harness

this setup ran a 13.1 1/4 mile in a del sol... all motor. he ran one pass on nitrous, and ran a 12.1. with the thicker head gasket, i hope for between 10 and 15 psi off the turbo. he estimated the hp now, N/A, around 275-300. so i'm shooting for 350-400 with the turbo kit on.

wish me luck!!!

 

I'm not at all a fan of the thicker head gasket 'route'. Especially if it's already 11:1... the thicker hg isn't going to make much of a difference on the compression unless you really put a monster head gasket on there, but then you run a higher chance of blowing it. I'd say just tune it for the 11:1 at a low boost and save up to put lower compression pistons in - like 10:1 or 9.5:1. If you're going to get a loan anyway, just get the pistons and a new HG and just redo that stuff... It's not hard at all... jmo.

Nice find though.

 

also, his reason for selling is that he lost his job, and has no money @ all. he sold his del sol shell, and is taking a hell of a hit on this motor setup. on top of everything, he's willing to drive it personally to me from indy, indiana.

so drop it down to 10:1 or 9.5:1 and run 6-8 psi?

 

at 9.5:1 you'll be able to run more than that, but it's going to need a decent fuel system to keep up. I wouldn't guess at a psi range, I'd drop the compression and take it to a tuner to determine what psi it will be tuned for. That's what I always did.

 

there is a wonderful tuner here in town. i can give him a call, explain the setup.. and see what he thinks. till i drop the compression, what psi do u think i should look @?

as far as fuel... i'm juss gonna upgrade the fuel pump. the injectors were described to me as the largest venom injectors for d series

 

I don't remember what the cylinder diameter is for the D16's, and .30 over isn't much of an over-bore, really just to clean up the cylinder walls and hone them for new rings. I wouldn't use Venom, they're in a close race with APC imho. I'd go with Precision, DSM, or RC. Likely 550's so you have room to grow and 550's will still keep a nice smooth idle.

PSI is a relative thing. Most people just get excited to talk about how much boost they can/are running. Don't focus on that, focus on power. The tuner will likely know how much the sleeves/rods/pistons/rings/hg can handle and what your fuel system will support. The compression is the variable in this situation so it's hard to say. SleeperCivicEX ran 12psi daily on his completely stock D16Y8 with RC 440's, an O2 simulator, Greddy 15g kit, Greddy type31 fmic, and a Greddy ProfecB Spec boost controller. I think he pushed 220 whp, but his OEM piston ringlands were dying at the end.

The motor you listed is really built for N/A. Before you buy it, I'd talk to the tuner you mentioned. You might be buying something that you would have to rebuild to run boost on. The compression, stroker crank, and cam are the areas of concern.

 

the dude who built it built it for nitrous. i'd assume a 150 shot wouldn't that different from 10-15 pis...

 

your ASSumption is 100% wrong.

You might want to do a little reading up on the difference in high compression nitrous motors vs. Forced Induction Motors. There are many differences between the two. & those who are running FI on High comp. have to be extreamly carful when tuning. Hell, you have to be extreamly carful every time you go to the gas station. plan to have a wideband in your car for safty if your gonna go high comp w/boost.

 

i'm lowering the compression. 9.5:1 would (i think) allow me to safely push 10-18 psi.

 

Ok, I'm going to stop posting now. This whole thing about 10 to 2355.332 psi is stupid. DO NOT WORRY ABOUT THE PSI YOU WILL BE RUNNING. It's sensless to spout out psi numbers on a mystery setup with a 'probably' fuel system and 'could be' components. Build/update the motor and fuel system for boost, trailer it or limp it to your tuner, let HIM decide at what boost pressure level you're best built to run. You haven't even posted what turbo you're thinking about putting on this setup so how can you talk about 18 psi? I ran ~23 psi on my setup, but I was BUILT and very well tuned for my setup. I didn't say "I think I'll go with......... 29 psi". I took it to a tuner, we went to a dyno and we tuned for 10, saw that it could take more and went to 12. I ended up running 12 psi on my first build and learned about boost and what it takes to make a motor that will take more, thus make more power. Build for POWER not for PSI. /soapbox :uhhok:
