I have blox type A cams right now on a b18c1 with itr pistons. Ive been considering upgrading to the blox B or other stage 2 cam. My question is, will upgrading to a stage 2 cam increase some of my low end? Top end will increase too?

 

it all depends on the size of the camshaft. and if they are using a larger primary lobe than stock. ull gain some low end but most of the gain is gonna be mid and alot of high. whats ur compression ratio at with itr pistons?

 

im at 11.0 cr right now. I want some more power, but my concern is with the midrange. I like having high end as well, but my car is a street car, not a dragger. I have all the bolt ons:

aem cai
68mm tb
oem gsr im ( i also want to get a different im, i know its restricting me a lot)
blox type A cams, cam gears
jdm itr 4-1 header
test pipe
jdm itr 2.36 exhaust

I was tuned at Church automotive, i pulled 192whp/148tq. My plans are to upgrade my intake mani and I am considering going with bigger cams. any advice is greatly appreciated.

 

well on my itr i made a huge gain from stock by going with buddy club spec 3 cams which imo are perfect for daily driving (but u will need new valve springs and retainers) and the occasional rip down the highway. the best way to make power is by porting the head, getting cams, port matching ur intake mani, and a good header with a 2.5 inch collector and a true 2.5inch exhaust.

 

and a good tune.

 

damn churches sure does tune real good. 192whp with those mods is good.

 

yeah, i have a mild build right now. i like my setup, its quiet yet still aggressive, but a little more power wouldnt hurt. I know my oem gsr intake mani is really restricting me, but what do you guys think about my oem itr cat back? its 2.36, same diameter as a lot of aftermarket exhausts out there. Do you think ill notice any gains if i went with a 2.5 inch exhaust?

 

i actually have an ebay 2.5 inch exhaust in my garage right now, if i slapped it back on,
1. would it give me gains over my 2.36 oem itr catback
2. would it f*ck up my tune and make me run lean and put my engine in danger?

 

4-1 header, 2.5" straight pipe, 2.5" es oval axle back, NO CAT, skunk2 intake manifold and you will make more power.

 

and annoy the hell out of every one else on the road lol a header with a 2.5inch collector and a true 2.5inch exhaust will make more power.

yeah, the reason i opted for the itr catback is because its oem sounding, yet its a 2.36 diameter. I had my 2.5 catback on for a few months, im using the ebay twin loop, and it was soooooo f*ing loud i had to take it off. I know getting a skunk or blox intake mani is something thats very realistic for me on my next to do list, but i mean, will slapping on my exhaust again make noticeable gains? Noticeable is the key.

 

the cost for bigger cams which includes getting new valvesprings, retainers and intake mani kind of has me wondering if i should just go with some itbs instead. My friend has a hookup on some toda knock offs that will be cheaper to do vs. all those other mods i just mentioned up top. I have the blox type A's currently, and they make good power. i hear they are supposed to be equivalent to s2s1 cams, and buddy clubs, though i hear buddy clubs make good midrange. If im going to have to upgrade springs and retainers, i might as well step up to a bigger cam since i have the 11.0 compression to match a bigger cam right?

 

if ur gonna do springs and retainers i would definitly go with a bigger cam. the bc3's are pretty big but will compliment ur comp ratio very nicely. i would seriously recommend a port though. get the head ported and port match th intake mani. a bigger throttle body would help too. but must be matched up to the intake mani.

 

192 whp? not to be a dick, but that seems generous for that set up.

 

maybe you should forward your question to shawn church buddy.

 

what intake mani will give me good mid range power? and does anyone know the diameter in mm of the opening on the blox intake mani? Im considering the blox intake mani cuz its so cheap.

 

Here's a manifold test my buddy did awhile ago. Check it out.

I'd be happy with thos numbers you have. I'll be doing pretty much close to the setup u have.
GSR motor
Mild P&P
JDM ITR or P30 pistons
Bubby Club 2layer head gasket
Blox type A cams
Skunk2 manifold matched up to TB
64 or 65mm TB
CAI
DC 4-1 header
2.5 exhaust
tuned on crome

I'm too in search of a cam that will perform more on the low to mid, and have decent top end. I don't plan to rev my car any higher than 84-8500rpms. I've been told that BC3's have good midrange.

 

yeah, i read that thread, but no one has info on the blox. i know i can get it for like 150 on ebay, which is pretty damn cheap, but i want to hear from people who have similar mods, and switched over to the blox intake mani.. Will it really change my power band around a lot, cuz i had a blox intake mani on my LS motor, and it made it feel like ****.

I dont want to lose any of the low end that i have right now, but if i can gain some low end, AND get some high end also, ill totally get it

 

i got it on my gsr good top end same as skunk 2

from the looks of it, I was going to say it would probably be similar to a skunk2 mani. I would just spend a lil extra and get the manifold in the link. It's tested and proven results in ya face y0. Or upgrade to a better header.

He is right, it is VERY generous, but only because churches uses a dynapack which typically reads higher than a standard dyno jet. So with all their calculations on their page you would be able to calculate your real wheel HP. So your car is producing 192whp on a dynapack which should come out to around 208hp to the flywheel, but on a standard dynojet, you should be around 180-184WHP which would mean your making around 201hp to the flywheel.

This is all on their website http://home.earthlink.net/~spc....html
