Hi, Looking for an RB25DET crank. Im in Tassie and im willing to pay all shipping costs. If you have one please PM or email me at [email protected] Luke

Na forged arias pistons but do give standard c:r, so thats why I thought it would stuff up c:r among other things if I used a RB26 crank.

bump

Standard turbo id say it was :bs!: also

I had standard head, standand cams, standard exhuast manifold with 3" exhaust, big injectors, FMIC, HaltechE11 and running bout 14psi and I got 269rwkw. Now I am rebuilding engine so most of that stuff has been upgraded expect for turbo, haltech and injectors. So the only thing stoping me to make more that about 320rwkw is the turbo, but I dont think I will upgrade as I dont want big lag either. Im in Launceston

So with the RB25 forgies and RB26 rods and RB25 head this crank would work without anyother mods? and would it be worthwhile in a RB25?

Hey guys, My engine is in the process of being rebuild and my crank is cracked and its stuffed so what I want to know is if I can use an RB26 crank in the RB25 block to make a 2.6L or will the RB25 pistons have the wrong comp ratios or something? And would it be worth doing if I can do it?

REALLY intersested in that RB25DET bottom end

This is probably a really stupid questin but could you put the crank in an RB25 block?

Cool! hopefully I will break through that 300rwkw barrier soon, I was thinking of going for a bigger turbo also but I dont like lag so I think I will stick with the 3037 for awhile yet.

Hey guys you have missed my point to his thread All I wanted to know would it be worth while intalling the haltuner to keep a check on a/f? I have no intention on tuning the car with it and it would be a shitload better than some a/f ratio guage from autometer or something shorly

Yeah well the cost of mine was pretty good, cost me nothin :headspin: I also got the O2 senor to go with it but doesnt look like your normal o2 senors, it hard to eplain what it looks like so ill take a photo and post it up. Im thinking it might be a 4 wire probe like your talking about??? So you think it would be a good idea to install it to keep an eye on things when engine goes back in after rebuild? Thank guys

Hi, Does any have one of these installed on there car or ever used one? Just after some thoughts on if they are any good or not.

Have you got any internal mods on this engine? R you gonna go RB25/30 for your new engine?

Ill take Rb25det bottom end

Yeah its a hell of alot bigger than stock, so I would say it was a .87

Yeah I was running the stock exh manifold, but I have now bought one of the stainless tubular ones from the states off ebay see how that goes dont really care if it cracks or whatever only owes me $200 and it cant be any worse than shitty stock manifold. As for the a/r I really dont know if its a .68 or .87 and I dont know where to find it on the turbo either. Does anyone know how I can find out?

Thanks Nismoid, I think the 3037 is a far more advanced turbo than the t04r thats way I dont really wont to get rid of it really. I prefer circuit racing over drag racing so im not really chasing huge hp, although 350kw would be cool, so I think I might just stay with 3037 and just see what it does and just go from there. To ugrade at a later date shouldnt cost much anyway cause I will always get good $'s for the HKS 3037. Cheers

Sorry I should have explained a bit more. My previous setup was on a internally standard RB25DET with a few bolt on's such as big injectors, FMIC, 3" exhaust, haltech E11, and a HKS GT3037Pro s running 14psi which I got 270rwkw from, full boost by 4000rpm, until wound up the boost too much and took the edge off a piston New setup has a strengthen bottom end too withstand the power increase plus the head been port 'n' polished with 256(in) 264(ex) cams and up rated valve springs, front facing plenum with large throttle body, 4" exhaust, turbo undecided?? I’m not gonna get much over 300rwkw from the 3037 but should be very responsive but will need to run pretty high boost to get that sort of power.... so if I went to a t04r top end will be a huge difference but how much response would I loose? and not being a balling bearing turbo would I be especially down grading turbo's? but I could run in easy 300rwkw without running heaps of boost through the engine so I really dont know whether to go ahead with it all :confused: Sorry for being so long winded :zzz:

Sorry but i already have a sale for it if I decide to go ahead with it thats why I was considering it cause I can sell mine straight away and I know where there is a really good S/H t04r for sale.

Hi Guys, Im thinking of upgrading my turbo from a HKS GT3037Pro S to a HKS T04R. With the 3037 before engine rebuild I had full boost(14psi) by 4000rpm but now with the new engine with a p'n'p head with 256(in) 264(ex) cams I would think responce would be a bit quicker, so with the larger T04R installed would I see much more lag? Is the T04R ball bearing or bushes type turbo? I was told some of the T04R's came with roller bearings, so how would you tell? Id like to have a reasonably responsive engine with good power, so I didnt know whether the T04R would be too laggy. Any sugestions whether I should keep the 3037 or go for the T04R or even go something different again would be helpful. Thanks
