I have a 95 GSR.

I basically need to know how much the DPR stage 6 headwork raises your compression. I have Stage 6 headwork done on my GSR. I don't recall the amount of compression points it raised. I have ITR cams on my GSR and was looking into getting a Mugen Headgasket to raise the compression. I just wanted to get an ideal compression for the Camshafts (so im not undercamming or overcamming). I remember reading somewhere that its around 10:8:1-11:0:1 or something like that with ITR cams. I just need to figure out what I need to do to get my Compression in that area to maximize the power of my setup.

Thanks for any advice you guys can give me.

edit: if you need to know my setup or anything else then just let me know and ill provide the answer.

 

any advice out there?

 

up for the night crew

 

cc the head and do a little math.

 

http://www.c-speedracing.com (i think, do a search) and cc your combustion chamber(s)

if the block facing surface of the head is milled and that balanced the amount removed from the chamber then the cc should be 42.7

 

wouldy you guys suggest a mugen headgasket or do you think ill bump up the compression too much for just ITR cams?

 

It should be fine.

 

in the case of portflow done heads the bowl work subtraction of metal about equals the amount taken of the deck surface facing the block so no loss of compression....if you take enough off of the deck you may be worried about valve-piston clearance with the bigger cams
