Sold.

I bought a new Precision turbo #6031 from GBody Parts 5 months ago. It has about 500 miles on it and it comes with a new HD wastegate actuator. It cost me almost $700. The wastegate hole has not been ported. No modifications or damage at all. Looks and is new. Big improvement over stock turbo...

I want to do the roller cam conversion from the TB thread using good junkyard GM lifters, dog bones and spider clamp to my '86 GN. One of you guys must have a set to part with at a reasonable price! I don't have the time to go hunting for them around here.

All the wastegate lines are new and clamped with tiny tie wraps. None blew off. That was the first thing I checked. I'll definately port that wastegate hole. The old stock turbo struggled to make 20-21 psi with the dump pipe. I should have known enough to port this one. I didn't because it was...

Didn't port the the wastegate hole. Always have in the past. Should I?

I don't have the wastegate turned up to get 22 psi... Just the opposite. It barely has pressure on the puck. I wonder if I should go back to my non-hd wastegate actuator.:confused: I agree the junk exhaust has to go. Hate to chuck it. It looks new and adds to the sleeper look. Kinda nice being...

Shouldn't the system control the boost even with the free flowing dump tube? :confused:

My alky kit has been working fine. It sprays at 10psi. I have a pressure switch plumbed into the nozzle line that lights the "Power Injection" light in the instrument cluster when the line pressure hits about 40 psi. This way if the pump fails, I'll know (probably too late). I need to add a LED...

Hopefully you guys can help me figure out why I overboosted and give me recomendations. First here's my setup: '86 GN, 112k, virgin motor. New PTE 60 Turbo w/hd wg actuator, new Turbo Tweak 60# injectors and TT alky chip set for 22# boost. Home made single nozzle meth/alky kit. 3 1/2" maf and...

Still got these for $80 shipped? If anyone is still thinking of doing this - I have some spiders and bones left plus a set of used GM lifters. Lifters have been disassembled and cleaned. Set of Spider/bones and lifters - $80 shipped

Never mind. I found it at the TR website.

I'm installing a stageright tranny brake. The pictures show the overrun clutch valve that must be removed to add a check ball to. However, it doesn't show where the valve is located in the valve body. Does anyone have a picture of the valve body indicating which one is the overrun valve? If not...

Stageright tranny brake Still available for $150? What about shipping to VT (05468)?

We use methyl alcohol here producing computer chips (IBM). My web searches say it's the same thing. We go through thousands of gallons. Does anyone know any more about it? My buddy handles it and spills more daily than I need for my personal use. I'm sure I can capture some of it.;)

It's finally fixed. I can't believe I didn't find this sooner. I had replaced the hoses from the solenoid to the wastegate actuator and to the turbo.... All but that 2" hose between the solenoid and the plastic reducer/elbow. Low and behold, it had a 1/4" split in it. It wasn't noticeable until...
