I have driven it a 2mm HG for over 6 months without boost the car felt much slower. Probably a 1.5 or 2mm would be good, remember the thicker the headgasket the more sluggish your car will get when you drive without boost.

ok i got one i am peiceing together my turbo kit but not ready to install it yet BUT i need to do some maintenance first on my GE. So my question is since I am going to change Timeing belt and water pump and front seals can I also install a thicker HG and run the stock engine without any problems for a while. Basically want to install the ARP studs and thicker HG and still be stock is thats ok or would I have to put on the HG and Studs when I do the turbo install

I would highly recommend that you do a compression test before you start spending money on the necessary parts so you'll have a base line to work from and if you have bad or low compression in any cylinders you can address the issue while the head is off!!!

This is how I look at it.you planning to pull the head.you gonna have to one day pull the oil plan to tap the oil return from the turbo.that's why I said to swap out the pistons and rings and rods.then you know for sure you block is bling-bling.
just wanna boost what I have now to get going.......blk&blu*j thanks for the advice I will get this engine compresion tested it's at 110k so well see
