Total Engine Rebuild- Need Some Help Now

[KennyJ]

I need some help please.

I was thinking about selling my R34 GTR V-spec, found a guy who said he would buy it, took it for a week test tour, and blew the engine on it. He then left town, and I can't find him.

Anyway, I had to take out the engine, swap cranckshaft, replace piston rods and pistons, install new turbos, and all gaskets. Etc.

After starting the car up, it idles on 2500rpm, the blow off valve seems to not be functioning, the sound which used to be there when I let go of the throttle is not there anymore.

I have no clue on where to start in the search to get the idle down or getting the resirculating valves to function again.

I took the car to a Nissan dealership, and they tried to adjust the idle using consult device, but it didn't work.

I bet u cleaned the throttle bodies.

U now need new throttle bodies to bring the idle back down

Hey Mafia can i borrow ur car???

Well, I don't have a good answer to why I loaned him the car for a week... He was a friend of a friend who I trusted.

Throttle bodies?

Honestly I am no mechanic myself, but I'm pretty sure the guy who did the rebuild have checked things as such, his guess was an electric fault or error...

I know its the throttle bodies because i did it when i was a 2nd year apprentice. Cleaned the throttle bodies during my rb26 build. Started up at 2500rpm. Did everything to diagnose then worked out its the throttle bodies. When u clean them it removes the sealer and now they act as if u have the throttle slightly open

[ARTZ]

is that only GTRs or do rb25s do it too ??

[GTSBoy]

No, it's only RB26 throttles. They're rotten things. This catches so many people out, it is not funny.

Strange but true, this can happen and does.

Search throttle body re-seal, I have done two now with rtv sealant and have done over 25000ks with no issues, it's easy and cheap, once u get the tb's off that is lol
