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!!!

    • Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.
    • Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using. 
    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
