im tryn to figure out the thickest headgasket for a stock bore 81mm type r motor i am going to run low boost on .........i know cometic makes a .051 but ive heard of thicker but cant find on the net. let me know ......thanks for the response

 

cometic has a .074 (2mm) and inlinepro has both 2mm and a 3mm

 

inline pro 3mm will def lower the compression good enough for boost, alot of F20C S2000 guys just run an inline pro 3mm headgasket with the inline pro turbo kit and call it a day.

 

i think im going with the inline pro 2mm or 3mm and i believe i need adjustable cam gears also......thanks people

 

Yes, adjustable cam gears are a must to get the timing back to baseline again.

this is a cometics .120 its really thick and took a month or to to get to my house because they didnt have it in stock and probaly still dont. im using it on a stock b16. it holds down 20psi with a full-race t3/t67h.o. on pump gas pretty well. its a pain in the ass to put on the timing belt and u definatly want to order a set of cam gears with them.

 

if you're planning on running low boost, then why do you need a superthick head gasket? many people get by just by running stock or .051.

anymore is just overkill.

 

exactly....
.... just get it tuned right. I ran a stock JDM ITR motor boosted at 9 psi daily. Never had issues. Tuned with Hondata S200b. It made 307whp at 7500 RPM. This was on a 57 trim T3T4.

 

i was woundering if anybody has run into problems with thicker headgaskets.I have a 86mm bore gsr setup with the 1/2 inch head studs and a .060 thick inlinepro headgasket and torqued to 75 ft pds and i get little drops of antifreeze down the front of the block. i also had the block and the head plained to be true

 

Because he is going to get boost hungry and blow it up. Build it.

Thats typical on honda,although coolant no,oil yes. The shop may have made sure it was a flat service but was it level? You will see many honda's with that slight oil leak in the front left corner of the block below the upper radiator hose. Atleast i see it all the time........
