Twin-cam

I tried some search.... but no hope....

So the car is euro ITR 98(11,1 CR), JRSC 5.5psi + JR FPR + Fuel pump... Cometic turbo gasket (now its approx. 10.3CR), DC JDM header, custom 2.25inch cat-back and decat pipe... According to the AF gauge, AF ratio si "ok", but i think that the cams overlap is killing the "raise of power/torque" on hi revs.. 6500+.... what cams would be suitable for this. There will be a proper Dynotuning with a standalone ecu in the future.

I heard that proper Camgear job would make te TypeR cams work better....

PS: the car was not dynoed jet, but a "butt-dyno" would say a 230BHP should be now in there :D The goal after cam and dynotuning is 250-260BHP

Thanx for answers....

OMG.... anyone?

Regular ITR cams are fine with the jrsc. Yes there is a bit of overlap, but it's not significant. My hp is still climbing at 9200rpm with stock cams. Actually, I remember a few years ago someone tried a gs-r intake cam and lost power. There were also numerous cam gear tests in the FI Integras forum long ago, and no conclusive gains were made on an ITR.

With proper tuning you should expect 200-210bhp. You don't have a prayer at hitting 250-260bhp unless you increase the boost around 8psi. Depending on how free flowing your custom 2.25" exhaust is, a 2.5" or larger exhaust may be very helpful at higher boost levels.

That was Mike Marsey (Rboosted717) that lost power when he switched to GS-R cams on his JRSC'd ITR. He lost power everywhere.

In order to make my JRSC worth a crap on my old car (EJ w/ B18b) I had to put alot of time into dyno tuning, and I mean alot. Trying different fuel pressures, AFC settings, timing etc. Ended up at 172/138 w/ stock timing.

I have tried many cam combonations. I have still made the highest HP with the GRS intake Type R exhaust.
The type R we just built @ 9psi made 267whp and 185 tq ( Intercooled)

My B20Vtec make 296whp and 212 tq with same cam combo.

I will add this is a full exhaust and 93 oct ( No monkeying with the numbers).

I forgot to say, there is a SAFC-II in the car.... is it possible to find any settings (fuel, Throttle....) for SAFC for a "Stock JRSC" setup?
