i am currently filling a bare gsr head for my b20b. Which OEM cams would be the best fit? itr and ctr cams are out of the question for now.........using 2000 si springs valves and retainers

b16a vs b16a2 vs gsr cams

this is my setup........

gsr head with itr lmas
replace all seals and gaskets
arp head studs and rod bolts
acl rod bearings
new mls head gasket
obd2 gsr water and oil pump
new gsr timing belt
rs itr pistons and rings <<<Can i use stock cams with these pistons?
Kms shot peen rods
Kms 65 mm ported tb and port matched stock gsr mani
hone cylinders
blox adj cam gears
adj fpr
havent picked out a header yet
2.5 in straight exhaust
NGK V-power BKR7E spark plugs
Magnetic drain plugs
neptune rtp tune

 

first, why are type-r cams out of the question. why go through all the effort and put in oem cams. you're not gonna make power without some sort of decent cam. i guarantee you that.

 

because of money $$$$ im on a tight budget

 

Save more money lol.

 

Great idea!!! Why drop $500 on a new set of cams when i could pick some up for $50 im only looking to make 170-190whp

 

you can buy used type R cams on here or some used blox cams for $250 or less all day long. I'd just wait, you're going to need to get it tuned twice which is a waste so I'd just wait unless it was my ride to work, then just put in gsr cams, baby it for a few months, then install better cams and get it tuned.

 

You won't make 190whp with stock cams ( with exception of ITR/CTR ) Especially with the C/R you listed. Do it right or do it twice.... or three times....You'll thank yourself in the end. And believe it or not your straight exhaust is going to make slightly less power than and will sound like poop. At very least BuddyClub Spec II which has a resonator in the B-pipe. Jus Sayn..

 

id have to disagree 180-190whp is very easy to make with b20vtec with the right set up.........will look into getting a better exhaust

so i am assuming gsr cams are the way to go until i can afford a better set up

 

So, your trying to say a buddyclub ll exhaust will help to produce more power than a straight through 2.5?

 

just picked up some b16a2 cams for FREE cant beat that!

 

Those are very small cams. They are fine to get you up and running, but you are going to want to upgrade as soon as you start pushing the motor.

 

gsr cams are more aggressive on a Stock P30 B16a3 head thats why they are considered a good and cheap upgrade for B16 heads. I was able to get 202hp by only using ITR intake cam which I got for like 200 brand new. Save your money and get yourself at-least some ITR/CTR cams.

 

his compression with the rs pistons and gsr head depending on how much the head is decked will be 12.1 thats plenty of compression to make 190 whp pending on cams

 

Thats why we all say he needs better cams... you need better/aggressive cams to go with such compression. At least itr/ctr!!

 

Blox Type B's or C's you'll be happy with the numbers!

 

Should i hold off on installing the itr pistons until i can throw some better cams in my head?

 

I would if I were you. You'll just be wasting time and money by installing the pistons right now and tuning it with b16 cams, which are a down grade in a gsr head. I would wait till you better cams and you'll only have to tune it once.

 

Do it now. Then when you get the cams you just have to drop them in and re-tune it. If not, you will have to pull the motor apart to install the new slugs.

 

+1 for Ramen

 

ditch the GSR manifold as well. take your time and do it right the first time. wait an extra 2-3 months to afford aftermarket cams. Dont try to rush into things and ahve to do things twice. Do it right the first time

 

I hear what your saying but this is my dd its been down for about a 2 months now and im ready to get it back on the road. I want to break 12's in my ef with this motor will be rebuilding the head later on down the road with better parts when i have more $$$$$$$ thats the biggest problem as i am currently unemployed and am still managing to get parts by selling my old setups............need 5 more items and im done yyayyy
