Hey guys!

I'm about as far away as possible from you guys but know that Aussies have the RBs down more than anybody so here goes:

I'm looking to do something completely different from anything in my area here in the States. And a properly built RB30 for my S14 seems like the perfect choice for what I want in a car.

I want a completely built engine because I thrash my cars pretty hard at the track and on the street. I want very little lag and smooth power delivery with a lot of torque (possible twins?). I already have my engine management picked out (HKS F-Con VPro), and want to have four maps: one for pump gas(just daily driving around town), pump + nitrous(for the highway runs hehe), race gas(for the race track), and race gas + nitrous(for the drag strip)

I am trying to build a car that is a jack of all trades, so to speak. I am looking for a very smooth driveable 400-450whp on just pump for a manageable street power, and then I can turn up the wick when I get myself into a pissing contest haha.

So because of that I need an engine that is very versatile. I like all kinds of motorsports and would like to build a car that does all things pretty well and is a completely different approach than what most of the people around me have. Any help, advice, facts, people to talk to would be much appreciated. My main questions were for comp. ratio(8.5:1 sound good?), turbo size(s) (leaning towards a Precision prepped GT3082, GT35R, etc.), and who to build me this engine (since I can't be in as close contact as I would like). I also was interested in finding out how well RBs respond to nitrous if tuned for it. I was thinking somewhere around a 150 shot?

Thanks guys!

I have an idea...

T04Z or T51R Kai?

What's like one size down from these?

I was just looking at the GT3240 on HKS' website, but I'm not a huge fan of HKS' turbos. Do other people make fully custom versions of this assumed Garrett turbo? I'm a huge fan of Precision's turbos. Do they do one like this?

+1 for RIPS, go to GTROC forums from the UK - those guys have money to burn hence why every 2nd car has a RIPS motor in it :( Their work is absolutely amazing - Rob is an awesome guy to deal with too (given us heaps of info re RB30s for nothing)

I would suggest pro engines in queanbeyan. they really know their shit and have built plenty of excellent RBs over the years.

Turbo wise the 3082 would be all you'd need to hit 400-450rwhp in US terms :P

Gas/fuel obviously more depending on where/how etc.

The GT35 will give you much more room for playing on PULP, here in AUS terms you can get 500rwhp from a GT35 without much trouble.

Then more on fuel/gas etc... so gives you an idea of where both sit.

Since you're in the US, why not go for Turbonetics items? Cheap as chips straight from the US.

Just heard of a lot of guys having reliability problems with them. Don't know a single person that has had one last a year here anyway. I like the GTK series though so I don't know. Thanks a lot for your help guys. I was leaning towards RIPS, now it's just pretty much definite. I'll keep you guys updated as the project starts to get rolling... :P

One other thing, will they already do the oil return line at the back of the head and things like that? That's mainly what I am concerned about. I have an RB25DET right now and know a very little about them so far.

I am just very meticulous about the car being built as bulletproof as possible with every trick utilized because I know how much I ask of my cars.

What other little weak areas should I be aware of when taking on an RB30/26? If this has been covered a thousand times I am sorry.

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
