Advisory - thicker head gaskets
I have seen some of my clinets being sold thicker upgrade gaskets for the head like HKS, etc .
These lower compression
On stock turbo cars you will loose spool up and also peak power with these gaskets - they are designed for guys with big boost turbos or with heads that have been machined many times
The way to get more power out of stock turbo cars is to increase compression
BTW - the stock head gasket is amazing - I have not seen one blow yet if you use the ARP head studs and trq them properly - I have run up to 575 whp on the stock head gaskets and o ring without incident
I say save your $$ for more power mods
OR - if you really want a upgrade head gasket - special order the PE stock thickness gasket from Nino - it will give you the upgrade but is not thicker

Don't think you need them - the stock ones hold up fine for dave buchur at 800 whp
Seriously the stock belts are good
Alaso - i have not yet tested these PE belts
They just look amazing !

Al, didn't you say a few months ago after you tore your engine apart that you thought that there would be a lot of blown head gaskets? I am referring to the pic that you included of your engine that showed that there was damage around one of the pistons. Did you maybe mean that if you are using the head studs that you won't ave a problem, becasue other wise I am a little confused.

We have seen many gasket flailures on stock motors with stock turbos - BUT ALL HAD STOCK head bolts - which strech easily and do NOT hold the trq in the fastener over time
IMHO - use the stock gasket wih the ARP head studs (properly trq'ed and installed - key) and you wont have any problems
Finally - to reiterate - IF you use the thicker gaskets - which lower compression slightly - you will loose power and spool up on the stock turbo
The highest whp stock turboed evo we saw had higher compression pistons than stock - 9.2 / 1 - good for 20 whp gain on stock turbo over stock compression

Al, Dont you have to be real carful with raising the compression on a turbo car? I always thought it was good to keep it low with turbo and high for n/a? Just thought i would ask becouse i would really consider it if it was safe to run 21-22psi on. Also i just got the Auterra Datalogger have you played with that at all? Just wondering what you thought about it.

the only time i would change it would be to hit 600whp stock block.

I agree with you 100%
