Hey i'm gonna put a GTR engine in my car, give me sum advice please ppl. And how much u guys think my exist engine worth? it's done 80k, i regularly service, timin belt, no oil leak anywhere at all...ICE Performance reckon it worth ONLY about $1500.

What's the better option? do the exist rb25det up or throw it out and rb26dett in?

Thanks guys.

well dunno about engines, but it may be right as you can buy a whole front 1/2 cut for $2500-3000 although price vary and depends on demand and availability at times when you buy or sell them... also depends on condition n milage of your engine.

GTR engine still cost $6000 up I think... so you're left with $4500 changeover... with that sort of money think of what you can put in your car, upgrade your engine or turbo, fmic, etc... well its your choice...

and don't forget if you put RB26DETT in your car, you need a GTR ECU as well, either you get factory from wreckers or maybe included in the engine if it comes in a package, or you get PowerFC which will set you back a further $1300-2000 depend if you get it 2nd hand or new...

with all the money ur gonna spend on the engine and fitment and all the other minor headaches like wiring looms and what have u I'd strengthen the RB25DET, like cooler, ecu, turbo, bottom end forgies fuel pump injectors will have u a very quick car might cost u a couple grand over, but remember the RB26 is obviously gonna be standard which means ur gonna have to make it quicker, more money on top of that... plus ur line is rwd which aint gonna be that much quicker than the RB25DET....just my opinion in the end its ur car do what u like bud... :P

that car at calder last nite with the rb26dettran a 13.8 he had the r2 gtr motor in it .. i was talking to him.. he spent 5 grand on that motor and olnt managed to get a 13.8 out of it,, ( heheh and i managed at 14.1 with a stocky rb25det hahahah)

if i were u i would get the rb30 bottom end and bolt on ur heads

u would probly gain more power that way

thats what im planning on doing anyways...

If you buy the standard GTR motor and drop it into a GTS-T it won't drop the 1/4 mile time too much!, also its a whole package that brings down the times not just the motor. i.e driver skill, car weight, traction and engine and so on..

But the RB26DETT is a stronger base and it responds to mods very well!, with good tuning and resonable bolt on mods there is no reason that a good streetable 500hp can be achived without touching the bottom end, try getting 500hp with the standard RB25DET bottom end!

So for the long run I would (and I am) fit the GTR motor and mod it when you can afford it. (as there is only so far that you can take the RB25!)

    • The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.
    • 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.
