Hello everybody. I have gotten hold of an RB20DET that is in a VH commodore for next to nothing, it has no exhaust after the dump pipe and the boost gauge reads 10PSI. The intake pipes have oil in them and it blows a small amount of blue smoke so i assume that the turbo seals are gone. What is a cost effective upgrade for the turbo, manifold and dump pipe to run a large amount of boost reliably? and i saw poncams on ebay and they seemed like a good upgrade aswell. i dont know alot about modifying these engines and would like to know as much as possible about making them go fast without spending a fortune. any help would be appreciated.

getting them moving without alot of money can be hard, but try grabing a rb25 turbo, and put 12psi through it. it will bolt on to the manifold you got now, dont worry about cams for now.

your first list of things to get should be like...eg

rb25 turbo

FMIC

fuel pump

Clutch

Piggy back ecu

Tune

that should get the old girl moving a little better. if you want more, then ul look at a bigger turbo setup later on.

All the help you need is in the form of the FI Guide, a sticky in this section

It contains many valuable links to read, that are filled with information

Cheers.

rb20 in a vh...

what a mad sleeper.

post up some pics when your finished.

that will be one kick ass machine once she's going properly, would look good with a group A kit/ whel arch flares on it with a set of fat rubber.

it would be worth holding onto if the body's in ok condition.

    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
    • yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
