Wanting to put in an intercooler on a RB25DET. Does anyone have any advice?

1) are the r33 gtr and gts-t intercoolers directly interchangable without changing the mounts or piping?

2) is it posible for the RB25DET to make that crazy noise the RB20s in the VLs make? If so, what needs to be done to the engine for it to do this?

Any other general comments are appreciated.

The factory GTR intercooler is a great peice of gear, with proven flow ability but for the money, you would be better served buying a complete off the shelf kit from the likes of Just Jap as the GTR cooler will require custom piping and brackets etc.

A cheaper option is putting an R34 GT-T cooler in. It's a side-mount like the R33 is, but the R34 cooler is thicker and flows a bit better.

If you're only chasing modest power gains I'd do this, otherwise go a front mount kit.

why would you bother putting a gtr cooler on when you can get new coolers for $150 and cooler and piping kit for $400. and i think you should do a bit of a search first there are many many topics on coolers. also dont block off your bov for that "sik flutter noise" makes you look like a wanker, and isnt healthy for the turbo.

this would be pretty much a waste of time and money especialy if you live in a hot part of aus.

the reason you would buy a GTR cooler and get custom pipeing is because of flow and cooling efeciancy. cheap kits are cheap kits. they dont flow, boost will drop and cooling is average.

also the cheap kits fit pretty average and most of the time the front bar has to be hacked to fit it where as GTR ones are made to fit.

GTR coolers are mass produced and have pretty poor flow capabilitys, the fins are very close together. also the $600 for a gtr cooler and then bout $400-$500 to get piping made up is goin to be better than say $350 kit from CRD in sponsors section. For most people unless your chasing like 1000hp or something stupid the cheap kits are fine, also the cheap kits have been tested compared to expensive ones and there is like 2% difference. For me $350 compared to over $1000 to not cut the front bar and have like maybe 2% flow difference just isnt worth it and most people will agree with that.

Is that the kit that requires to chop the battery tray or does it run the pipes through the existing pipes?

Cheers

Josh

I personally dont know what to do to mine at the moment as I have I think to take the battery and get a smaller one but maybe ill run the pipes to the exsisting one... anyone have better ideas?

actually,the r34 gtt sidemount is good for 200 odd rwkw/awkw and wont heatsoak too badly if you are using a stock/factory option front bar which is designed to flow in that direction. using the factory shroud will also help.

i think for ~$200 and DIY install (easy as piss), the r34 gtt cooler upgrade on an r33 is a great idea. this is what i have done second time around on my stagea, first time being a GT-AH cooler/custom piping :wave:

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
