R34Poncams In R32, Issues

[nltd]

i bought r34 tomei poncams cams because they wre cheap, so i decided to put them into my r32. was told they would work with a r34 CAS and abit of wiring work.

got the car to start, it idled for about 1 hour, but when i turned it off it wouldnt start again. i cranks but wont turn over.

HELP?!

engine was just put in, not sure what to check.

the reqirint work is simply reversing the wiring on the CAS plug.

any information would be appreciated!!

nooooo. due to the heaps different profile of the solid lifter r34 cams they wouldn't be suitable with hydraulic lifters.

fitting in and working are 2 very different things. ....

I've never heard of putting 34 poncams in a 32. Its not something that logically sounds right but I cant be sure it doesn't work.

r34 cas on an r32 ?

You idled it for an hour ! - why?

Tried putting it back to the way it should be

Then go through the process of - Why my car wont start

Hopefully no damage has been done that cant be undone.

Edit: Good point ^above. Suppose if its an R34 RB25 engine - sweet. If it's an RB20 DET

^^ yar, we wont know for sure til he comes back on here but im leaning on the idea that he has a 25neo

In the thread tags it says 'RB26'

[GTRsean]

Need a tune. Fuel map would be out for those cams and you probably fouled the spark plugs.

Pull your sparkies and check.

im going to go out on a limb here and say 26. need more info tho.

Can't see thread tags on phone.

It's my understanding that you should not let a new cam idle, it should be run at around 2000rpm for 20 minutes to run it in. Not sure what Tomei recommend.

thanks for the help guys, its an rb26 btw.

all good im ripping out the poncams n getting r32 ones. i got an r32 cas so itll b wired up properly again. hopefully nothing major is wrong with it. fuc kme dead. LOL

Mechanic let it idle for 1 hour and took it around the parking lot. do u think any major damage has bee n done?

[nltd]

and the reasoning towards thsi was, i found r34 poncams cheap. and the guy at skylines spares advised it could be done. zzzz

[nltd]

if anyone needs r34 poncams type b. holla.

[Ben C34]

I think letting it idle like that can wear the cam lobes. I would be changing the oil and filter for sure.

FYI,

The r34 poncams DO work in a r32 rb26.

My car was just tuned yesterday and the figures came out alot better than expected.

yes, nothing wrong with using r34 cams in 32R, how much better are we talking? low and mid-range improvement

[SiR_RB]

r34 GTR poncams can be made to work in an R33 and R32 GTR but you need an r34 GTR CAS and swaping afew wires over

+1 Running in a new camshaft requires fast idle for approx 20min (or whatever the manufacturer recommends), then varying load i.e. hills hills & more hills. This also good if it's an overhauled engine, for bedding in rings (low RPM, wide open throttle - to force the rings into the liner).

[SiR_RB]

so which wires need to be swapped to make the r34 CAS work in a R32 GTR ??
