sr20 and roller rockers

[Lee]

as the b15 sentra has roller rockers, are you aware of any other sr20 motor in another car that also share roller rockers? (primera/g20/etc)

if so, any idea where i might find the lift/duration of these cams?

Thanks

(aren't i a PITA!)

in this engine sub-forum.. theres a thread about JWT turbo kit...

in the second to last post some one states that G20's have roller rockers... or something along those lines... check it out

i did see that, but no really what i was looking for. may call clark @ jwt. see if he has any ideas. if they just had the ecu ready, cams w/b out the door and a peiced together turbo kit would be my project. maybe in a year or so. then again, i could always retrofit since i live in a no emissions state. Thanks anyway...

What do you mean by cams w/b? You can't use the old non-roller cams in the roller motors. I think some guy in south america tried it and it ran like shiet. JWT is working on a set for the newer motors though.

JWT doesn't have the 99+ ecu's ready yet. ETA end of year

The G20 came with a rocker roller motor starting 2000 model and over. Mines a 99 and has the non-roller rocker motor.

i think what was meant in that thread is that the 2000 and up g20's have roller rocker sr20de's...

I meant if the ECU was done, i would scrap the cams search and do a turbo kit.

true, like the 98+ ecu's too. seriously, they do have the cams technically "done", but not in release since they are still testing.

depending...you know their schedule

As did the 2k sentra se's. (same engine )

i guess i need to work on how i word things. what i was mainly asking was is there a sr20 from japan that has/had rollers prior to the 2000 year production. if so, i wonder what the cams are like and if a swap from one of the rollers would be beneficial. i didn't mean from non roller to roller...from roller to roller.

take for instance the non roller sr20's. the b14's would benefit more from a 91 intake cam vs. stock b14 intake cam. this is what i'm looking for, except from a roller to a roller. (not thinking about 91 cams in the roller car, just an example.)

hope this makes more sense.

Yeah now that you describe that...I see! And yes that would be something to look into.
