Skyline race car RB20det GTRNZ

This was originally an R32 GTS-t type M. Now built as a race car with the original RB20DET engine with minor mods pulling a conservative 22bls boost with 413hp at the wheels. We plan to go further with the engine to see what we can pull out of it, yet still making for a usable track engine. Why? Because every one changes to the bigger 2.5, 2.6 or 3 ltr and we want to put the car up front with a 2 ltr which should be quite possible with the rest of the car dialed in properly.
This was my first time out on a slick tyre hence bogged down on the start line still would not have stood a chance against the EVO even with a good start.

Only 413 bhp? that is a huge amount out of an RB20-DET.

I dont even know how this is possible. people are posting lots of money mods on this engine and on average i only see 280bhp...320bhp tops really.

what ECU are you running with this? i assume you have the z32afm?

im puzzled with that power claim mate!

the car sounds like it has it tho

@simonize999 Check out the dyno video on youtube. 308KW ATW RB20. I use Speedtech Motorsport in NZ. To pull this power I have thrown the AFM away and run a MAP sensor instead, this gives unrestricted air flow. I am using a Link G4 ecu.

@Leithyl what else have you done to it. Minor mods to run 22 psi is out there. plz reply

@simonize999 really because i know 3 people in my area with 350 + hp rb20dets with stock internals + stock cams.

Well done Leith, I have always said RB20DET were a good engine if built correct, man you made something that is not only competitive but reliable too.

My wifes first turbo race car is going to be a R32 with said RB20DET although not quite as tuned as yours, but Grady and Bob at hitech to finish the build of the ECU and injectors, however we are using a smaller turbo.. but using the G4 link.

very cool non the less

Great build!

I'm running a std RB20 w/ a GT3071R @ 16PSI and 360RWHP.

Awesome driving too, I love your description: "Because every one changes to the bigger 2.5, 2.6 or 3 ltr and we want to put the car up front with a 2 ltr which should be quite possible with the rest of the car dialed in properly." THANK YOU!

Great vid, Great driving. Really enjoyed watching someone else out there giving an RB20 a hard time and getting good times

@foodley123 Nah, not a good idea. The selector forks are weak as fuk. Any fast changing with break them, I've done 2 and fuked 1 set of syncros already . If any upgrade is to be done there it'd be a dog box at the least

[foodley123]

Dude, you need a different selector - your losing shift times with it - look for either a nismo short kit or I think there are some after market ones that are even shorter - but they will give you a bit more feel - I think you can use the same for all RB Nissan boxes. wouldn't be a mad exspensive exercise.

@Leithyl i know what you mean, if your going to do cams in an RB20 you might as well just go solid lifters and a smaller duration high lift cam since the RB20's head ports are so small.
