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 GTR cooler u will need the piping and the cooler (front mount) also the impact bar infront of it if u want to get it to fit with out chopping.

this means u can get engineers cert

the flutter si due to the vl's not having a BOV. so remove your bov (and just put a plate over the hole) and you will have the same flutter. then welcome yourself to the world of lag on gear changes.

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:

      R32 GTS/GTST non driven wheel speed

      By Roy · Posted

      Another complicated thing is to run Z32 alloy hubs which have wheel speed sensors for ABS. You need different tie rod end, and you need new bearings on the upright etc. I did that as part of a major refresh when my front kingpin bearing flogged out., Alloy was a little lighter, runs a bigger bearing , gives a few extra mm in wheelbase as it moves the wheel forward in the arch (cant run crazy but can still get 8ish comfortably).   All in all glad I did it but was a head fark as tried it once and abandoned it the first time. sav man swung his spanners at it and got it working so using his guidance on GTR/Z32 tie rod ends etc and the required mismatch of parts was able to make it work.  Probably a 2k upgrade all said and done :(   I think the best bet is just look around your front wheel and see what you can pick up rotationally. You see old Escorts, E30s etc all get very creative with front uprights and the humble old angled alloy bracket.

      RB gearbox options

      By Butters · Posted

      If your HP goal is reasonable and you are not drifting. Buy a new R34 box.  If the above is not true, buy a wrecked R33 box and put a gearset in it.  CD09 are not as strong as you think and the cost of / mess around of the conversion puts you in gearset territory.    Also the deal above is awesome,, get that

      Got this r31 silhouette flood car to rebuild.

      Just got back from a little hands-on with a G58 Baron....I was thinking about this... ..best I can figure it, that pinny was tail-ended ...I didn't really think about the wiring, because all that mattered was the tank and pump cradle (I think I mentioned the pump itself I couldn't vouch for)...which didn't matter, as you said you'd be replacing the pump anyway.... ...'for some reason'....and I imagine this is the panel shop's doing... they've replaced the cradle wiring with a metre of 7-core trailer loom, and attached the loom plug (from a different car) to that. The actual cable run from the top of the pump cradle, to fuel pump harness end in boot, is maybe 60cm in length...so I've no idea why they did this... ....the connector in the boot of the pinny, is not going to help you here...because in theory, it should still be present on your car. On top of that, because they've done what they did, we have no idea which colours of the trailer cabling, have been connected to what on the fuel pump cradle (pump +/- , shield, fuel guage/low-level senders)... ...this means, best approach is to remove the pump cradle, and re-work it now ...not later. That is, if you were going to replace the pump, do it, replace the soft lines at the same time...and sort the wiring out (replace that trailer cable with the wiring loom off your old cradle)...

      Fake ARP bolts?

      Well, maybe not. The main feature of Chinese manufacture seems to be incredibly variable quality, coupled with an apparent willingness to find a way to see even the stuff that fails QC. So the military could still take the cream of the production run and somehow sell the "sellable but not really useable" stuff to the stupid round eyes on the other side of the world.
