Roger's advice is good, but the stock bolts can take way more than 15...

PSI. Many prople use the stock bolts because you don't have to take the whole engine apart to get the head gasket again. The raceware bolts do have a higher tensile rating, but I have not heard of the stock bolts failing at the max boost limit of the 24 or the 26. At 25+PSI your problems are going to be detonation, not bolt failure.

BTW: It is not the raw boost number that is valuable, but the combination of exhaust, intercooler efficiency, and timing. I know a lot of gomers who run high boost and the timing ends up so retarded that they lose a lot of horse.

Very true but my case is little diferent.
My car is not exactly stock. The timing and fuel is taken care of with haltech and a straight thru 3' exhaust with 10'x32'x3.5' intercooler with race ported head will do its job. Stock turbo? looks are deceving its a k26 with a 15 degress clip on turbine wheel and a
T-04 60 trim compresor whella fully ported, I call it the special K good up to 600+ hp
I have a shop in Toronto and all we do is turbo upgrades and high horsepower conversions.
I deal with ARP but they dont have 5 cyl 20v kit even thou they are the same as the vw 16v they stil make me buy the VW kit anb the two missing bolts I have to buy separet witch is a hasle.
If you want to see some pictures of my car go back few posts to here are some pictures of my car.
