Hope this doesn't turn in to a shit storm like on ns.com.
I'll just make a few comments here to clarify some things, maybe it will stop some people carrying on like the children on ns.
No-one is bragging or making any claims here. It is was it is. It's cheap, laggy, probably won't last. No shit.
Just a fun afterhours project.
It was built using an old smoking motor that was lying around the workshop.
The engine was stripped down, cleaned and reassembled using all the original internals with new rings and bearings added.
A metal headgasket was used and the standard springs were shimmed up to give a little more seat pressure.
The standard rb20det cams are still used but with some "special timing" Without a doubt this is the main limiting factor currently.
One of the reason so much boost is used is to overcome the flow limitations of the std head/cams.
A spare gtr inlet plenum was cut and welded on to the std rb20det inlet runners. The alignment of the runners is off and i am sure this is doing more harm than good, but hey, it's all just for a bit of fun.
There are some cheap bolt on parts used. Cam pulleys, fmic, throttle body, exhaust manifold and wastegate are all ebay cheapies.
The whole project was done as cheaply as possible, in our spare time afterhours, while on the piss.
Now the original plan was to see what sort of numbers could be made from a std internal std capacity rb20det using a remapped factory ecu.
I figured anything over 300rwkw would be a decent number. I also fully expected it to shit out and throw a rod or something.
Pretty much started at 20psi and went up 2psi at a time until the motor blew or it stopped making power. Neither has happened yet.
Personally i am surprised at the result. I can only imagine what it might do with some big cams.
Of course i would never suggest or recommend this as a sensible setup for anyone or anything.
I just think it is interesting to see what can be done with cheap parts on the baby rb.
I'll put some photos up when i can.
