hey guys, i'm a newbie and my questions for you are: will the USDM ITR cams fit in JDM B18C GSR? and how much power am i gaining in doing so estimates? and do i have to tune it after installed them???? thanks

 

you should tune or get a chipped ecu that can run the proper fuel map since you will have a higher lift.. you will get around 10-12 hp depending on your mods.. i recommend a tune.. they do fit

 

alright thanks bro!

 

I'd get an aftermarket single runner intake manifold also, then get a tune. That way it will run close to an itr setup.

 

actually, right now i'm running on the skunk2 pro IM and 70mm TB (which is where i'm loosing a bit of power there), i will put a smaller TB like about 64mm, hope that will help.

 

whered you get the cams?

 

i would also recommend valvesprings and retainers.. i saw an itr break a retainer and if you are familiar with heads you would know what happens when you drop a valve into a high revving motor.

 

the cams coming from a friend's 98 type R


hm, sounds like too much work and i dont know much about it. i wanna do all motor, but i dont know how to do it myself and too risky to mess with it, it's still better to have a jdm b18c now then if i messed it and no turn back, so that will cost me tons of money hahahh thanks

 

actually its not too bad... it seems like its difficult but not too bad... i thought it was difficult when i was learning, but i like to let people know to do things right the first time.. especially if you are taking the cams out anyway

 

they sell a tool on ebay to do it nice and easy.. and 2 ft of nylon rope and you are good

 

so you rec. the valvetrain also? i haven't done anything yet , ppl said i can just put the ITR cams in and get it tune but other said valvetrain needed so i'm confused there.
