If I go with an external gate I have to switch out the downpipe correct?

ECU GN

Got a brand new Precision 6466.

What controller do you recommend?

Looking to upgrade from the stock header setup. I have an internal wastegate with a stock style 3 bolt turbo flange. Looking to run 30 pounds of boost with a 64-66 turbo. I'd rather not have to change out the downpipe and convert to external waste gate.

What does everyone's car idle at with a roller cam? Right now I can get my stock motor with 120 pound injectors to idle at 800 rpms. Just curious if its possible to get a cammed car under 900?

I'm in Pittsburgh but I can ship.

I bought these heads brand new 2 months ago from GN1 and decided to go a different direction. These heads are for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. The heads feature a 170 stainless valves and exhaust valves are stainless 160. They have new keepers...

I have a set of brand new champion iron heads CNC ported. Still in the box. Bought 2 months ago and decided to go a different direction with an all aluminum motor.

I have an offroad test pipe that I would like to put an electronic cutout kit on to. What is everyone using? And recommendations?

Lift is 0.330/0.325 duration is 218/212 on a 112 lobe seperation. We are going with 1.60 rockers.

So far I purchased the champion iron CNC ported heads, got a cam from Bison, GN1 stroker kit, and converter from Dave H.

What is everyone doing for roller rockers and shafts?

Sounds good. I just talked to Dave and ordered the converter.

Yeap I am painfully aware. 16% slippage aint going to get it done. Yes the transmission was built. I am taking both out and going with Dave's transmission and converter.

12.05 at 112.5 with 28 psi thru the traps at 5560. I couldn’t leave under boost with these tires. Beat 60 foot was 185 leaving at 2000. Tune was spot on. Data logger shows huge stretch in 3rd gear and it just stays at 5400.

Everyone is right about this 10 inch PTC converter. I ran the car yesterday. 17% slippage going through the traps at 5650 rpms. Had the MT 255/60R/15 on the car. Absolutely horrible, converter is going in the trash where it belongs.

Thank you. I will call them again and ask them specifically about this part. I appreciate the feedback.

As I mentioned here Feedback about roller camshafts I called and they said their stuff is not compatible.
