O.K this is a two Part question. (1) what should i gain with a good tune. and #60 inj. (2) what mod would gain me the most in the terms of 1/4 mile times/horsepower.

My car- major Mods: G.m Stage Two.
Sportsline springs.
Stage 3 Spec clutch.
Light weight Flywheel. (Spec)
Zeitronix wideband (not installed)-next week.
Injen cold air intake.
Vibrant header and downpipe. (4-2-1)
Zex 50 / 75 horsepower wet shot.
Ingalls engine dampaner.
Solid Trans. mounts.
H.p tuners (no idea how to tune.)

My questions are: should i go with
- Header back exhaust.
- Save for ported head, and custom camshafts.
- Heat exchanger
- Snow performance cooling mist
- smaller pullys


What order would you buy these mods? And why. Also, dont forget about my questions at the top of my post. (By the way, i just bought the #60 injectors. they will be installed when i find someone who knows how to tune with H.P tuners.) I will also buy d/r and axles before next spring.

 

axles and slicks.

easily the biggest change on the 1/4 mile in that list.

 

i figured most would say that. i just want to hear the cam's lol. I added smaller pullys to the list as well. ( this would only happen with a tune and cooling mods.)

 

If your really serious about getting headwork and cams, I would go for that first since that will take a fair amount of $$. Then you could buy the "small" stuff.

 

oh im serious. but, i dont know if that will be enough time to save the money. and i dont know if i want to replace my head now. or wait untill i build my new engine after the "suposed" superchargers come out early next year.

i guess maybe i should have left d/r and axles off, i know im doing that before spring anyway

-took off d/r and axles.

 

definately get axles slicks regardless man. your already pushing way more hp than street tires can really handle.

adding more HP that you cant get to the pavement would be a kinda waste

 

In that case, I would do cooling mods. Kill that heatsoak!

 

thats what i was thinking too.

do you guys think that the header/downpipe back exaust would do much?

i really dont know much about exhaust but in my opinion the stock is pretty big.

 

I agree you definitely need the axles. Not only will they let you launch harder but with the power your running the stock ones are bound to break.

 

i am getting axles. reguardless. just trying to think one step ahead.
-morning bump, any other comments.
