Hey guys, I have an R32 GTS4 and i recently blew my little RB20DET sky high =P oops. (shitty oil pumps i say)

I'm wanting to get a new engine back in there, but obviously don't want to waste money on another RB20.

I was thinking of putting in an RB25DET manual out of a Stagea (or convert to manual if needed), but I was thinking was IS the difference between an RB25DET RWD engine and a AWD one? really?

From wot ive gathered it the sump studs in different places, but i could always drill that out and modify so perhaps a RWD RB25DET could b bolted straight in with sump modification into my GTS4, perhaps by modifying my RB20 factory sump or? Has anyone done this or heard about it?

It's obviously cheaper n easier to source a RWD RB25DET than one out of a generally newer Stagea, that are generally autos too...

If anyone could clear this up for me conclusively I will be extremely grateful!!!! =P

RWD RB25DET into GTS4 can it be done? I will do all the work myself with a mate including the engine swap. proficient skills. doable?

Thanks in advance guys.

Have a sweet one! = P

You would have to redrill the sump bolts, other than that it should all be fine. Obviously you'll need the 25 ecu etc.

If you do decide to use a Stag engine then your sump will bolt right up but if the engine was an auto you'll have to remove the auto spigot bush and put a manual one in before bolting your clutch/box on.

I probably wouldn't use a Neo Stag engine unless you have full custom management as the stock auto (manual's are a lot rarer) ecu's for these things have the gearbox control unit built in.

my mates got a gts4 rb25 -from stagea, thats the go dude unless u wanna lose awd capability.

You didn't read the post properly champ. RB20 AWD sump modified onto RB25DET from a RWD ser 2 at least, I was pretty sure i just had to change the sump studs, which i have the $3000 drill n pieces to do so easily =P meaning it would be an AWD RB25DET.......

And bubba. Thanks mate, u know what ure talking about...finally my question actually answered! That's wot i was thinking too =P cheers for the tip on the neo's control units. I wouldn't have gone for one anyways unless it was cheap as, but not at all anymore, unless i'm going straight to aftermarket management, yes? Depending what pops up for what price i will either modify the RB20 sump n onto RB25 with the RB25 ecu obviously, or knock in an RB25 out of a stagea most likely non-neo. If u guys find any cheap ones in Perth too let me know- I'd appreciate it!

Thanks again bubba,

Have a sweet weekend guys! =P

Do what i did. Get a R32 GTR front cut and swap the whole thing over, wiring, ecu, etc

Really easy to do and you get to keep the AWD system. Man you cant go pass that. AWD kick ass off the line. Theres no doubt about it.

Heres a link to my conversion done R32 GTR RB26 into R32 GTS4

Keep it AWD!!!

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
