You don't need a new wiring harness or anything...

Everythings "bolt-on" except for the fuel lines

god god god,sorry but damn i just love third gen trans ams

[1989GTADRIVER]

Me too....!

There's a laptop presently sitting on my passenger seat to get the tune down on the PROM. Then we'll see what kind of #'s I can squeeze outta this thing without melting it...... hahahah

[1989GTADRIVER]

It's not a stock motor....unfortunately.....

It's got a GM remanufactured block that has been bored .040", with dished pistons and a .040" deck height.(grrrr)

I used a Felpro 1094 head gasket to recover some of the compression lost with the dished pistons and larger deck height. So there's definately more to be had with this combo. Some may say that the short cam duration 211/219 will hold me back as far as RPM capability, which I won't argue about... But for now I need to learn how to tune

Hedman Elite Longtube Hedders PN 68468 and Flowmaster American Thunder Systems PN 17233

Check out Dyno 1 and Dyno 2....... I think the exhaust sounds different now that the intake, cam and heads have been changed.

The car was running very lean, so we only did 1 pull.

Time to go home & start tuning!

What size injectors did you use for this car?

[V8TransAmGTA]

[kuulkatdadieo]

I have the same exact car, except motor. And was wondering if the HSR fit under our GTA hoods fine or was it tight? Thanks

[firechicken76]

Sweet GTA, good numbers for the TPI. check out my 88 ls1 gta. havent dyno'ed it, but its got all the bolt ons.

[camaro88iroc]

does the Holley SR Intake bolt right on with the stock wiring harness, or do you have to a new wiring harness?
