ok guys, im so up in the air on what to do here, so here goes...

right now the setup is as follows:

-usdm STOCK gsr block with 130k on the clock
-ported p72 head (not sure on how well it flows, got it this way, doesnt look to be a backyard job)
-crower valvesprings and chromoly retainers
-buddy club spec IV camshafts
-spoon gears
-skunk2 IM
-bdl 70mm tb
-3" short ram intake with stack
-tri-y header (small tube)
-full 2.5" exhaust (no cat or anything) with apexi n1 muffler
-jun flywheel
-b16 hydro trans

The car has been on the dyno a few times, and with stock tb and 98+ itr header it made 186whp 121 wtq and peaked at 8900 rpm...

now, i have rings and bearings to freshen the block, and i was planning to just mill the head .030 or so to bump compression a hair, im really only looking to get it just a bit over 11:1, i was wondering if that is really going to be enough for these cams? or if i should just start looking into some pr3's, or even a 2.0???

and help would be sweet, and yes i know the tb is a little big, ive got pretty much nothing in the setup really, so im pretty happy with it as it is...

 

i know someone has something to say... ive searched and searched for months on this, and jsut wanting any random thoughts on the subject

oh, and i guess goals woudl help, shooting for a 12.9 on bfg's... car is a full weight 94 coupe civic dx... and looking for whatever whp it takes me to run the 12.9 (figure 105-108mph? 200whpish?)

oh and im not at all worried about the fact that "if something messes up i wont have much to mill"

just looking to bump compression without stripping my good condition gsr block down just yet...

 

11:1 for those cams..........wont cut it at all

 

crap, thats what i was worried about...


so, what are we talkin here? i know these are supposedly streetable cams, so im assuming they would work well on a streetable compression ratio...

ive got some PCT 81.5mm pistons, but i really dont want to use them...

also have the option to do a b20 block, but i dont have hte money to do it right and use a girdle and whatnot...

also crossed my mind to throw the gsr crank into the b20, with the rs machine 84mm pistons, but money is kinda tight...

i can do the destroked b20 for about 700 bucks... including block and everything, or do the pr3's in the gsr and only have to drop enough cash for a set of pr3's (already have new stock rings and acl bearings ready for the stock rebuild)...

i jsut trust the gsr block more (girdle, squirters, etc.)... opinions?

so some pr3's and a .030 mill </TD></TR></TABLE>

im runnin club IV there ill but my compress is up there

 

so im going to clay it anyway, but, anyone think milling .030 and using 2 layers of the headgasket will cause p2v issues?
