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!)

    • I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.
    • Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary? 
    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
