Ive searched the Blox 2s or skunk 2's and the crower stage 2's

Im picking up a usdm automatic motor out of a 2000 prelude with a blown head gasket.
Forgive me I've been tuning b series for 10 years and this is my 1st H. I was wondering how much i could safely mill the head, I'd like to bump up the compression a full point, which cam would suite my setup? If needed machining the pistons for more valve clearance is not a problem. My goal is a stock block with no port and I'm hoping for 210-220whp.

Skunk2 pro series intake mani w/ innovative heat sheild gasket
70mm TB
3" intake
Camp 1320 tri-y h2b header
3" exhaust
balance shafts removed
Machined crank pulley and lightened oem flywheel

any advice before i purchase some cams would be great

Why do you bump a post only minutes after creating it? Relax man . . .

Your power levels are attainable. Skunk2 makes nice street cams, I have seen the blox been successfull as well. You can also look into the Rocket H22 cams.

Any would be a good choice in my book.

Good luck

I have major anxiety and had too many cups of coffee, thanks for the help

do not mill your head to raise the compression...the gains are minimal just resurface the head and block to make everything flat for a fresh hg...

if youre not going to sleeve the block you can acquire some mahle 11.5cr pistons to play around with compression safely flat valves and milling heads .030" are a waste to me...but to each their own

word of caution the max. you can take off a h22a head is .008"(approx.) before timing starts to mess around so make sure you have cam gears if you mess around with the head height...

look into pro1's and such 2fastgsr is pointing you in a positive direction as well...be patient though and plan everything out

ill disagree with your pro 1 suggestion. with no attempt to raise compression and lack of head flow i think that the s2s2's would be better. i know he mentioned milling the head but i agree that is not the way to do it. skunk2 says that 11:1 should be a "minimum" compression for the pro1's.

mahle pistons seem to be working for the people who are using them. you could also use type s pistons.

Search for dynos with stock h22 bottom end and the Pro1s. then you will realize why i said this.

Great advice guys

my previous H motor is around 11 CR and the s2s2 work really well both on street and track

i use s2s2 cuz the pro1's not out yet by the time. by like other said, pro1 need more CR

GoldLudeRay

if milling more like .030 like i have done too my usdm h22,,, make sure too get adj cam gears and get on the dyno,,,,, that is where the power is too be found...

milling does make power,,, allmost all serious scca and solo race stock class cars have too run stock pistons and valves,,,, so alot of them raise the compression via milling, that is how they gain power.

i do agree milling isnt as good as mhale piston or type-s cause u get alot more p2v clearence w those pidton cause of the valve reliefs,,, but milling the head cost like less 100buck,,,,, but u can only get so much w so little money,,,,,

im hoping my car makes good power and runs good times, like this w the milled head!!!! if it does im going too feel much better about spending the money on a set of pistons,,, we will se how it wrks out

pro1''s or skunk2 stg 2 are bothe good street cam choices,,, peak power is about the same but idle and mid cam are stronger on pro1's when dialed in right

ESP.net

skunk2 pro 1's or old skunk2 stg 2's matching valve springs and retainers...

compression always helps Type S/Euro R pistons 11-1 comp. and pro 1's is a good setup.

dont get me wrong, im not saying that the cams wont make power....however; the car does not need that aggressive of a cam. its not all about having the biggest cam you can get. the power difference between the two on this set up are not enough (imo) to sacrafice the driveability (idle lobes). again just my opinion

What are the blox b's equivalent too? the s2s2 or the pro1's?

I agree with you and did not merely suggest the Pro 1s because they are the "biggest" cam available. Hence why i didnt advise the pro2 or the like. The Pro1s do idle better. Read around my friend .
He also said he was looking to bump the compression so as he gets higher the pro1s will react better. either way

ilikehonda

i wasnt trying to say that the pro1's were the biggest merely bigger than this build needs. and as far as idle, i was not saying that the idle is bad but the pro1's to lope a little and the s2s2's have factory idle lobes

fekyoride

I checked Blox's site which states the only cam they offer for the h22 is the same specs as the skunk2 pro series 2's. Kinda bummed considering i can get the blox h22 cams for about 340 out the door.

Any word on Blox offering different stages of cams?

2fastGSR

Anyone can make up "specs" on a cam. Hell I could start my own company right now, copy and paste skunk's cam specs and label them Jake's Fantastic Super Cams.

Point of the rant is dont always believe what you read. Go from testimonial from users and not just what you read of someone's website.

Thats my opinion. . . .
