Hi, i have been finally joined the broken RB club. :D

I have been considering many options of late in regards to what motor to build or throw into my GTS-T

The car is setup for track work and once this saga is over i would very much like to see it back on the track,

My goal is to have around 300rwkw that is reliable, an leave the motors almost untouched internally

I have the ability to build a 2530 or buy an rb26, so people in the know could you please give me some opinions

and also what is required for the rb26 to work eg. sump info.

Voice your opinion

what motor should i go for???

Well really you got to think. You have an RB25 in there allready (not sure how modified it is, but if it does have a lot of aftermarket parts, you can use them all), so the most cost effective and easiest conversion is the 30 bottom end.

well true your right i have the parts for a 270-300rwkw setup, but would the rb26 have a logical reason to put it in????

Well if thats the case than there isnt really a need for a 26.

If the motor was bog stock than i'd suggest 26 but not if it means buying turbos, injectors etc all over again

expect to spend a couple thousand if you just want to drop your mods onto the 25/30 (money to cover block modification to suit RB25 head + misc modifications to make the loom/water lines etc fit. (more if you aren't doing the engine in/out work yourself)

i assume you have an R33? all the sensors/engine mounts/ballancer/water pump/oil pump etc bolt up to the block. careful using an RB25 sump make sure it doesn't have the fins that stick up below cyls 4-5 as the crank will hit them.

would i get away with just using an rb30 sump??

nismoid..

this is the exact reason i didnt go rb2530 as the cops here in adelaide would send u over the pits as soon as the car rolled out the driveways which would mean that the car would have to have another rb25 dropped into it for it to pass insepction.. too much trouble IMO!

rb25 is a good engine.. just stick with that if its a streeter..

ive buggered the bottom end, no point staying with it imo when i can upgrade, may as well while its broken. Rb30 should resemble some sort of low down torque unlike the 25.

    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
    • Got just the wing painted and fitted up to the existing boot. Big visual change and about time after having a GTR wing sitting in the shed since 2018 Headed up to Mallala with a quick obligatory stop in at Boliver OTR Oil control mods seems to have worked. I checked the catch can after session 1 and there was a dribble of water/e85 with barely any oil in it. After session 2 and 3 there was almost nothing and I stopped checking after that. so either great success or catastrophic failure/block of the external breather The GTR wing made a noticeable difference in the 160-185km/h sweepers. It was a very hot day for the cars at over 33C but the previously done cooling upgrade/ducting/water sprayers meant I never saw over 60C intake, 105C water and 100C oil and temps would drop back down very quickly once I shut it down. AD09's are a decent tyre but certainly and expectedly a step down when compared the the CR-S/AR-1 I have had on the car for years of track days. The handling characteristics of my car which I often describe using the Tony Hawks Pro Skater balance mechanic where either side of the center is understeer/oversteer was much more pronounced with no "green/safe" zone in the middle. However, imo it steers well/easily during oversteer largely thanks to the custom ACOSTAL front end. Enjoy a loose lap POV with my mate giggling away as a passenger.   Group photo for Peer Pressure Racing made it back home and gave it a wash Overall a great success compared to my previous two track days where i cooked the Starlets motor and blew up the new diff in the R32
