I have a 98 spec jdm itr with two layer hg and tuner2s. Cams are not degreed in. When i did timing belt after changing the hg it ended up being a tooth off. Im going to do the timing again and see if i can get it dead on.

I am planning to dyno tune car, but really am lookin for some quick settings to try to save time on the dyno. Head is not shaved and block is not decked, just two layer hg.

Thx

Best to tune on the dyno since you're going soon anyway. then you know its right. You won't lose a lot of time after the initial timing and settings.

^^Agreed get the motor in time and set the cams to 0 degrees, let the tuner make the call from there.

When I degreed them on my gsr I ended up with +1 on the exhaust and +3 on the intake. It made good power on the dyno but I heard from a couple of knowledgeable people here to start retarding the exhaust cam and see what happens. Ended up retarding the exhaust 6 degrees on the dyno and made a pile of power in the midrange and up top. Actually went seven but dropped the engine vacuum and power and went back to 6. End settings were -5 exhaust and +3 Intake.

what was your setup? with your username I would assume you were boosting on them.

Mostly stock gsr, B16 pistons, on the motor only. PSI GUY is dead.....now i have a mullet mobile....lol.

Just curious, when you say you picked up a ton of power after adjusting the gears, how much are we talking about? 3-4hp or like 5-10?

like 10-15 in the midrange, car was a lot stronger on the street.

Interesting, may need to hit the dyno and retard my exhaust a bit.

That's ALOT of separation. Good to hear though. Wish we could see an overlay of the graphs.

When I go back to the dyno I'll get them to do an overlay from last year.

Do you know how much power your engine made as a stock jdm itr? I am curious at what the difference/outcome will be! Please show the results! !

Im not going to be going back to the same dyno so numbers are going to be a little skewed, but car was running consistant 13.4-13.5 at 99-100mph in a 94 integra

The Tuner series camshafts like overlap(Advancing Intake, Retarding Exhaust). These camshafts work well with this type of cam gear setup.

Car ended up making 218hp 147tq on mustang dyno using hytech/dtr side exit header and 3" race intake goin out headlight with velocity stack. Going to be a couple weeks before i can get car to the track to back up those #s

Nice power!!!. You mind posting the dyno graph??. Would like to see the spread.

For quick 'drop in' settings, try +1, +1

JRSC01GS-R

we adjusted cam gears to +2 intake and 0 exhaust, tuner said without measuring valve to valve clearance he wasn't comfortable going any further. i wanted to advance intake a lil more and try retarding exhaust some but car made good power so I didn't push the issue.
