I'm having an issue holding fuel pressure with my Racetronix Double Pumper. Above 15psi of boost, fuel pressure drops pretty hard. I have a magnafuel regulator and -8 feed and -6 return. Do these pumps have an internal bypass that could be causing an issue or could my regulator be having an...

Now that the swap is done and the car drives its time to get to the details. Anyone have any input on how to make the factory tach and boost gauge work? Any schematics or thoughts would probably be helpful. Thanks guys.

Heres my project, just got it running and driving about two weeks ago. Still needs some suspension work and more fuel for all the power that can be had but I sure do like driving it so far! this was before we finished up the dp and exhaust Any questions feel free to ask, I have alot of...

I have a 4l80e trans out of a van and the dipstick is very short. What is everyone else running for dipsticks on your 80's?

I'd like to pick up a 109 shortblock/longblock to at least let me car see the street once before the snow. If anyone is withing 250miles I am willing to drive. I do not want to spend the money on a built one, stock is fine.

Looking for a decent lockup converter about 3k-3.2k stall. Prefer used but if not I'll find a new one from a vendor. Just trying to find a cheap one to see if it's the right amount of stall to spool my turbo.

So my mods are listed in my sig, I'm really dissatisfied with how the car pulls currently. I actually think it was faster last year with the stock cam stock heads and the 56mm turbo. I was wondering for those with bigger turbos if the stock manifold is severely choking out my car, and if there...

The car isn't slipping in gear, but it wont shift. I have to bring the RPMs up to about 3200 and let off the gas then punch the gas again to make it shift. What do I need to be looking at guys? I'm stumped?

I have a stock tq converter and as far as i know stock trans in my car. I added a new turbo and on the dyno I can't get it to make more then stock turbo numbers. Its just all kinds of goofy. Am I blowing through the converter? How would I know? Or am I slipping the transmission? I know what...

Feeler for prices on a known good and not about to blow or locked up already short block. If I don't find one soon I'm going to be in turbo v8 world with my 85 T...I would rather keep it v6 buick but such is life...Any one got one laying around? 4.1's or 3.8's will work :)

Would like to find some 100# valvesprings, some new hydraulic lifters, 80# injectors and I think thats it haha. Lemme know if anyone has some laying around.

The track opens on April 9th and I'm still finishing up my minor restoration on my 85 T. With this in mind I will definitely get a few chances to take it to the track. Some of you may remember what parts I have on the car, and some dont. So I will go over everything that has been done...

Any one have a hotair turbo for sale? Stock replacement no shaft play is good, a ta33 or bigger is better...to an extent. Need one asap. will post pics of carnage done to my stocker later on.

I was wondering if a 150psi pump included in the AEM kit would be able to support one m15 nozzle throttle body/pre turbo on a hot air, and two m7 nozzles in the intake manifold post turbo...

curious as to how fast the stock turbo has taken these cars. can't seem to find that out anywhere. any help would be greatly appreciated.

Now that the car is running this well, I wanna go 13's. I feel these nexts mods could probably get me there. Switched my M5 nozzle to an M8 for a lil more methanol. Going to find a 160* thermostat Some may not like this but a heater box delete will allow me to fab my own 3" dp with an RJC...

Went to the local track tonight had three runs. First time leaving from idle ran a 15.0 at 93. Second time up (i had acl surgery last week so can't left foot brake it) I right foot braked it with my crutch on the gas pedal, left at 0psi and pulled a 2.3 short time and a 14.8 at 92. Third time I...

Car keeps stalling out on me. Cleaned the IAC, and throttle body. Reset the IAC multiple times and keep playing with the throttle blade set screw. If i can get the thing to idle right then when i put it into drive it stalls. When i set it to idle in drive right then in park and neutral its at 2k...
