275,000 kms rb30e turbo intercooler managment, injectors many drift days track days and deca days @ 200 + rwkw no issues :wub:

p.s i don't do cheap shit conversions if you want cheap find someone else. I do it right

also it doesnt have to be an rb20det thats jsut what i found myself, havent much experience with turbo r31's i was previously a silvia guy, anyway 200kw on anything sounds pleasing lol and in the light r31 id be happy with anything making 140+

way to hijack my thread idiots, get ur own or are u not smart enough

Dry your eyes mate.

Smart enough haha your the one needing advise on putting a 20 in a 31...

:)

owned lol

I'm pretty sure the comperssion of an RB30ET motor is 8.5:1.. but the RB25DET is 9.0:1 as you said.

RB30ET is 7.8:1, RB30E is 9:1.

Even on 98pulp they do tend to ping a tad with 15degree's static timing so they really do need an ecu remap which is possible with the vlt ecu's.

Or pull a few degree's out of it.

The cam specs are also slightly different.

Providing the rb30e bottom end is in good nick to start off with there's no reason why they don't push over 300,000km's.

Sky30 is a testament to this with the purchase of his s/h rb30e motor that did 270,000km's, pushed 240rwkw through it for ~20k then 300rwkw for another 20k and now 380rwkw. Strong motors providing they aren't detonated/leaned out or over-reved; its all in the tune.

I would do it; just be sure to run it up on the dyno to ensure its not pinging its arse off and it will be all good. :yucky:

    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
    • Wrinkle black will be a thing for both
    • As I wait for parts to be delivered, I have managed to procure via a contact a R32 Nistune ECU......for now I just want to monitor what the car is doing but eventually.......who knows where we go 😂
    • To back this up, I'm always looking on the outside, seeing the level, and then opening it up anyway, as I'm worried the level I've looked at, is more so a scunge line. Then you end up dipping your damn finger in it too depending on the type of tank you're looking at just to make sure I'm not going insane.   PS, Mark, polish up the none moroso one a bit and then give it a clear coat. The Moroso one looks to be way shiner (not mirror polished, just shinier) and it'll still look weird with the two different alloys beside each other. Either that, or Id probably paint them a flat black...
