Project RB-Z

docaam

Ok project moving in another phase Engine SWAP. As people on some forums know I sold my current setup with everything including radiator, ecu etc.

I was planning for a while to swap RB25/30 NA setup but after reviewing it a lot working with different heads and lack of upgraded cams in some heads dropped the idea. Moved to VQ35DE/HR for which wiring is a bit of a pain but then couldnt find HR engine and where I found with online wiring service (2k$) and engine cost over all project costs jumped.

So in between talking to few installer came across something unusual and interesting taking it as a challenge.

VQ30DET, its a rare engine same quad cams but block is much stronger then VQ35 and low compression as it comes with a turbo from factory.

As per some forums stock engine is running on 5-6psi and gives around 280hp and turbo can go easily upto 14psi before playing with the wastegate and power can go upto 350ish but still needs to be checked, as people are running cars upto 500whp on stock block and its holding great so there is good potential in the engine. Being a destroked version compared to VQ35 its revs better as well. One other things which my mechanic said engine is without VVT so can change the cam gears as well if needed along with cams maybe for future.

After looking for a while found one here, as per Air flow meter clips seems like came out of 2002-2006 model Nissan Cima here it is






Bought the whole things with 8 speed CVT gearbox lol, and engine mounts sway bars and most importantly ECU and harness.

Was lucky found a CD009 gearbox out of 2006 JDM 350z as well.




Covers removed from engine



There will be alteration needed in cross member, whole exhaust manifold on engine and might need to move the turbo a bit as well.

I opened up the engine so do some colours and for some porting the exhaust and intake inlets, engine was clean but too much slug inthe oil sump seems like car was running on those 30k limited oil, but compression came out good. Only problem was turbo came out broken one fan was missing so will change that from the shop got the engine.

Fan was chocked and one side one is missing, as for the size seems bigger then RB25 turbo more like GT25 series size.



Engine opened up




Intake and TB


Lower intake manifold


These are parts I dropped for chroming will do a contrast in these three




Pulleys as well for chroming (sample chrome piece on left side )




This thread is going to be busy again
