cheap as in 163 dollars. thats retail though so i am sure it could be had for cheaper. grex is from trust or greddy, they have a division of there products called grex. so i am certain any greddy dealer could order the headgasket. they have thicker headgasket to they are 1.0 mm all the way to 2.0 mm. the 1.0 and 1.2 is 163 dollars and 1.4-2.0 is 188 dollars. i guess i would just order the 2.0 mm if its 20 dolalrs more. knock some compression down and have a headgasket that isnt gonna blow ever!! also could someone please tell me what head studs people are using for hihg boost applications? i already ordered the turbo set up and plan on running about 25 lbs with it. its a gt25r turbo. gt35 compressor mated to a t-28 exhaust housing with a .86 ar turboine housing. its dual ball bearing. good for over 400 hp at the wheel flows 44 lb/min and full boost by mid 4k. thankschezina wrote:Whats cheap?
