Cometic and InlinePro both have 3mm head gaskets...
Is it better when to get one of these and run a stock compression engine or is it better to keep the stock gasket and get lower compression pistons?

 

Either way would be good, I have a cometic and it works pretty good but I think I would honestly spend the money to get the low com pistons.

You have a GSR 9.5:1. My friends gsr runs with stock headgasket and 10psi with no problems.

 

i want to go more than 10
im looking at 350-400 whp

 

you'll make 350 to the wheels easy. inline pro 3mm headgasket. afc/fmu/440 injectors/race gas and tuning. stock internals.

 

im taking daily driven
i dont care about race gas and **** because when i see a car on the road (not that i street race or anything ), I dont want to be running out of my car and pouring in some octane booster.

Im going FI with pistons and rings, so should I keep stock compression pistons in the situation that I need to take the turbo off for some stupid reason

 

Well stock compression on the b18c isnt that high as it is so if you get forged pistons staying around the same compression will be fine. You'll make a little more power and spool faster.

 

but then i need a really good tunner to be able to tune it so there is no detonation, right?

and in your set up, do you suggest getting the thicker gasket or no?

 

definitely go the piston route if you seriously plan on making 350whp. at fmax we produced 350whp @15psi on a stock b16 but it only lasted a few runs. melted a piston.

 

cool...
what do you suggest for a compression? im a noviece (i know that spelling is wrong) tunner, so keep that in mind

 

i wouldn't drop a street driven gsr any lower than 9.5:1... but i'm sure many would disagree with me. i went 10:1

 

so I should shoot for 9.5:1 then?

 

was that with a thicker headgasket ???? and it still melted a piston ??

cheers
