Re: Turbo Rebuilds....Piston Upgrades....and modified camshaft p

you can buy camshaft at zcarparts.com note that you have to get the ones fr the turbo engine as the n/a's are different, and pistons i am sure somebody can help you out with that.

Re: Turbo Rebuilds....Piston Upgrades....and modified camshaft p

I would just buy a new t3/t4 instead of getting the stocker rebuilt. heres some good sites for turbos:

www.phoenixturbo.com
www.vecco.net

You cannot bore the block to 3.3, Vg30Dett Rods (stock & aftermarket) fit the vg30et block with no modification. VG30Dett Pistons also will fit if used with Vg30dett rods but the compression rated for the tt pistons will be slightly lower if put in a vg30et because of the different sized combustion chamber. If your looking for modest power best place to get them is msa schneider regrinds cams for them at a very good price

check out http://z31.com/cams.shtml for camshaft stuff... i know for a fact the motorsport auto cams are still made, and i've heard that they're some of the better ones you can find out there.. but that's just hearsay, does anyone have experience with these cams?

He can do what ever you want, I had my stocker modified with screwed in thrust bearings, and a much larger compressor wheel. It was a nice increase from stock. Even at stock boost levels the car had stronger pull.

Re: Turbo Rebuilds....Piston Upgrades....and modified camshaft p

Thanks 88hybrid,SteveZ31

thats my issue...see i dont know what i want cause this is my first time tackling a project like this...i didnt want to spend too much time and money on the project...but i do want it to be something....id be the first in my family to attempt a rebuild of any sort....there are 3 Zs in my family one belongs to uncle 84 auto with t tops the other to my pops 84 with 302 5.0 mustang engine conversion...and of course mine which was an NA till i bent the valves and decided to got turbo swap with it...so im guessing here that i just go with a camshaft modification...order the cams and take the heads to the machine shop....im assuming they will need the new camshafts before performing the work required. and i guess with the turbo id talk to him about improving on the stock turbo to get better results from the engine....oh ummmm whats this i hear about metal headgasket being better for the turbo engine? are those available from nissan motorsport also?

the bottom end of the vg block is almost indestructible if it is in good working order and you dont detonate.
