Lizard928

There arent many people who have really put in big cams on the stock 5L.

That will change as of the beginning of march.

The 928 heads are great flowing heads. You do need stiffer valve springs, as well as I do recommend new lifters (VW ones are good). I have put in mild regrinds on GT cams into a GT, and it REALLY woke the car up. Going with a strong stock S4 5 speed which a few other GT owners had driven and said it felt stronger than their GT's the GT with cams literally walked away from me.

Once I have the numbers regarding the cams, I will be posting them.

I did also get your email, and will respond to it tonight.

what i want to do is get my car to equal the performance of the new camaro and mustang. if i can get my engine to at least perform aswell for 10k, i can live with that.

I agree

it all depends on your intended use......for a primarily street car...boost is fine..since you only will be at full throttle for short bursts..... A track car requires a bit more planning...an ORR car....even more

Well your 91 should be no slouch.
From all the advice above, you should first make sure its 100%
You need a X pipe if you don't have one
stage 2 Murf super charger
One of the guys to tune it

Someone here who knows can tell you the RWHP but it should be 500 I would think. Depends on boost/pulley size

Then go kick some ***
you could add some meth injection and NOS as a surprise package

I have Morton Engineering cams on my 5.0L 32 valve S4 engine.

My review: they rule.
