OK boys and girls here's the deal... I just picked up all the necessary parts to go to run a big turbo setup on my SR. I'll be running a Garrett GT25/40R w/ a .86 a/r with 555cc tomei inject., full stand alone (Modification Analysis and Development) and I want to run 18Lbs. Do you think I'll have issues with blowing my head gasket with that much boost? I wanted to wait till the end of the summer to do the gasket and head studs because I'll be putting in HKS step 2 cams as well and I wanted to just do it all at the same time. Think I could get away with waiting or what???

 

after stage 2 or 17 pounds i'd go with a copper one.

18 is the start of stage 3 i believe.

 

well if ur gonna spend money on a nice turbo engine managemet and injectors y skimp 200 bucks on a nice mhg. dont skimp!! ull end up paying more in the long run

 

get a kevlar one they hold far more boost

 

I've never heard of a kevlar HG. Care to share where I could find one and how much more coin they are than just a copper one???

 

kevlar composite same as break pads, thats what it sounds to me me never hear dof it i heard of felpro hgs wich arent copper but hold 30 psi . now was it felpro or am i thinking of something else?? =(

 

cometic makes em...
