Motor taking a shit
Motor taking a **** Well after some diagnosis for my cars rough idle, I found out that my motor is worn. After much research on 355 set ups I have decided to do an lsx/t56 set up, but I was planning on doing that mid next year. I really didn't want to dump money in a setup that I wont use but it looks like that what I'm gonna have to do. So my plan is to just do a stock rebuild on a 350 I have and just cam it which should make my car move pretty good(mid 14's is not bad for now)
A G92 equipped 90-92 Speed Density 305 TPI matched to a T5 is capable of high 13's with just full exhaust and tune...so, I think its safe to say you'd definitely be hitting at least 13's in the 1/4 with a 350 TPI, regardless of your car being an 89 with a MAF.
Do some DIY porting on the heads and intake system and throw a decent cam in there to get you by. Will be a FUN street light to street light car. Besides, if you had anymore power, you'd probably blow that T5 to bits. Is your trans World Class or Borg Warner?

Really? **** YEAH! How much whp do you think I'll make? I was guessing around 250-260, pretty accurate? Its a WC t5 I'm not too worried about it, it should easily last a year. I'm not putting any sticky tires on it or anything. Mid 13's possible? I have 3.73s and I'm gonna put a full exhaust and do some head work with a decent cam too. I'm still researching what exactly I have to do for the 350 swap, I pretty much know what to do now.
Good luck though. At least yours is driving. My third gen is sitting in the driveway as a rolling chasis with the new motor and trans in the garage. But my setup is a little more complicated...
Your swap will be a snap. You really dont need to do anything...just drop in the 350 and tune.
No money, I really want to! I'm thinking in about a year I want to start an lsx/t56 swap. I was gonna build up a 355 and 6 speed but after ALOT of research on the set up I figured it would be better to save just 1k more and go for the lsx swap.

I'd rather just save up a the rest and just go for the ls1, I want my car to handle really good. If I drop an ls1 it will stay stock but I'm going to do everything I can to suspension and chassis, brakes too. I love autoX, SO MUCH FUN!
im trying to save up for my front suspension and some ctsv brakes..
i wanna do the same.
Like jeremy said, you're going to have alot of fun with that 350 tpi setup until you get your ls1. In my first black 91 z' (jeremy's car now) I had a mildy cammed 350 tpi with exhaust, crappy 2.73 gears, and a sloppy shifting auto trans, and tune.
It ran an 8.9 @79 mph with a slipping 2.0 60' at irwindale...about a 13.7 in the 1/4. Had I ran with slicks I could have probably made that car run a 13.5 in the 1/4. Sounds like you'll have a similar setup but with a better tranny and gears so yes mid 13's are easily possible.
The guy I bought that motor from for that car said the motor put down 275 rwhp which sounds about dead on. So expect a number in that area with at least 350 rwtq. Just do your research and you'll be fine.

Damn that would be really nice! I'm just gonna drive my car till the motor starts making some noise then I'll send my 350 to get built, hopefully my motor will last just long enough that I could just go straight to the lsx swap, cuz I put like 4k on my cars a year on average so it may just last.
