Has anyone ever put a thicker head gasket on h22a1 (3x the oem thickness) and have problem with timing belt. Please advice what the fix is. Any smaller cam, belt, or crank belt pully needs to be change?

 

why so thick? you'd also need to degree in your cams with adjustable gears for that big of a change. I'd imagine the belt is going to be a bitch to get on with that thick of a gasket.

 

yes, it's hard to put it back on but I can deal with it, I just found that I could use adjustable gear to offset the degree a little bit. thanks

 

why are you running such a thick gasket? so approximately .078"!?!

i am running a .051" gasket and in order for me to get the belt on, i have to loosen the cam caps and lift up on the distributor side of the cams to lower the gears and slip the belt on.

 

This guy wanted to turbo it, so I am doing him a favor because he doesn't want to rebuilt (resleeve) for more boost. I think this will bring the compression ration down below 10:0:1, USDM. but, I will use the adjustable, I think this should fix the problem.

 

its going to drop the compression wayyyy below 10:1. You will be in the 8 range. Why drop the compression so low when 10:1 is feasible?

 

No offense but have you at least used the compression calculator? theres software around here that allows you to calculate your compression level with a couple inputs on your behalf?

Just guessing at what size of headgasket will yield what compression sounds like a unprofessional way to play the game!

Also, as the above has stated whats wrong with 10:1? 10 is realitively safe to boost on provided the tuning is sound!

How much boost does he want to do on a stock block anyway? I wouldn't go more than 60-100 hp over stock, so ideally I would think 6-8 psi would be more than adiquite (in my opinion). That being said, dropping the compression ratio is deffinitely unnecessary. If he was going to boost like 20-30 psi, yeah than drop the compression to make things more reliable. I'm no expert in boosting, still learning. So hopefully some one can correct me or agree with me on this matter, so you are informed and arn't wasting time/money doing unecessary work.
