Thread: what should i spend $2k on for 98 gtp

With those miles I would keep the money for a new motor an trans and suspension... But headers are a must, zzp reconditioned heads are a waste of money, just have a machine shop redo yours if there's anything even wrong with them, or buy a used set of low mile l32 heads with the slightly bigger valves. and the ssic intercooler setup isn't worth it, spend a tad more and at least get the stage 2 core and fmhe. and of course get or make a nice intake setup

I'd spend the money on a good trans. And rebuild the top end of the motor. The last thing you want is to spend $2000 on go-fast mods, and have the engine blow.

205K miles is up there, so make sure everything is up to snuff before you go modding.


Also, I dont think the Water to air IC is very viable...least I've never seen any car running them besides the Aussie 3.8 RWDs.

Liquid To Air Power Coolers Performance Racing Products?????????

This doesn't fit between the supercharger and the lower intake manifold on a 3800, is that what you asking?

thanks guys the top end is where i was gonna focus all the money and i did forget to mention that i already have kyb gr-2's with the eibachs and anti pogos... the ride is amazing...so ur sayin the ssac ic isnt worth the $135 shipped and i should get a morad trans and engine... just saw a motor trans combo on miorads ebay site for $1599+shipping w/110k mi

I like my SSIC, I was able to go from a 3.5 pulley with 17degrees WOT timing to a 3.25 pulley with 19 wot timing and a 12.0 AFR. Is it as good as a fullsize. No. Does it work? yes

its not SSIC...its SSAC..totally different intercooler.
Ones liquid---liquid
The other is liquid-air.

I wouldnt get just a stock transmission. If you're planning on putting down 300hp, your gonna start tearing up stock trannies.
See about a TEP tranny, or similar trannies.

I'd say if the bottom end is good, just rebuild the top, with go fast stuff, and be happy.

BUTTT. Get 3.29 gearing, and you'll be faster!

Theres no point in trying to make big power, if you cant get it to the ground effectively.

A basic 3.4" setup will be fine, anything more and you'll be pissed when you have a messed tranny.

Someone dare put 3.69's in a race transmission with a custom tune on a stock pullied car with slicks and get close to 12's?

Do it.

Get a custom tune if your modded, if not, get either a Reptile(member on here) or an Overkill pcm.

3.69s will get better acceleration, but sacrifice MPG, due to the gearing.
3.29s came in GT's and are geared better for acceleration than the GTPs 2.93 gears.
