Just bought a 1986 GXL w/ a clean body and really really low mileage (about 57k on the engine and body) , from what i read....the n/a's get 140hp at most stock(s4)...and even less hp at the wheels....is their any good mods that can unleash more HP at the wheels??? im looking to hit at least 170-180 hp at the wheels(na)...is it possible ...even with an n/a engine??? any imput will help thnx!

 

Full exhaust
Intake (cold air if you want to build it)
Ported Manifolds and TB (TB doesn't do a whole lot but if you got the time why not)
Lightweight flywheel and good clutch
Port the motor (will make hitting those numbers a lot easier)
Remove all emissions if you can (the cat will hold you back in the exhaust and if you ditch the cat the rest of the emissions is useless too)
MSD6a or something similar
Upgraded plug wires
Etc.......


The list goes on but those are some starters.

 

nice list!!! thx!

 

when you get a lightweight flywheel it comes with the counter weight. Is our engines balance inside or out? and how hard is it to install a light weight flywheel

 

We have front and rear counterweights that match the rotors you are using.

 

So i would have to go into the engine to rebalance it?

 

howabout you look in the archives for one of the lists?
buuuuut, for starters, intake, exhaust, and a fuel computer like a S-AFC should bring you safely into 14's.

 

bump

 

No, just get the correct REAR counterweight for the rotors/front counterweight you already have.

 

port manifolds,intake,exshauast.

 

Most aftermarket light flywheels use the stock AUTO TRANS rear counterweight.

A few companies are coming out with flywheels with built in counterweights. These are straight bolt on that requires no additional counterweight.

The need for or against a counterweight SHOULD be listed with any flywheel you are looking at buying.

 

where in the tansmisson do i put the counterweight? and how complex is it. I plan to rebuild the tansmisson so would it be an easy install then?

 

I goes on the rear side of the flywheel.

 

dang ska, jack threds much I say all of the above and Greedy E-Manage for tuning. I'm still learing about E-Manage but it sounds like a very promising tuning tool

Handles like a dream and dynoed 150RWHP

 

I did alot to my na to try to get hp and I am still not where I want to be you can see my mods below I hope after the turbo I will be close. Good luck modding your n/a it can be a lot of fun.
