Hello

I would like to know if a R32 or 33 GTR intercooler is too big for my R32 GTS-T. I mean is the intercooler too big for the size of my engine? Will it be better if I go with a intercooler made for my size engine? I do not want lag from putting on the GTR intercooler. My engine is stock, except I am going to put a RB25 turbo onto it. I have intake and exhaust done.

Its not just the cooler but also the length of piping...just bung any proper core on there...you're not going to notice much difference between the 2...but that core in your link looks like its seen better days...

And you will never get rid of lag on a rb20...

Not a lot of lag? The one in the pic has all of the piping, the gtr one I can get from my friend doesnt have any piping.

To make the best install of the GTR cooler you'll need all the piping.

I put a GTR cooler/bov setup in my 32gtst and the fit is excellent, a little bulkier under the guards but a much nicer install than shitty china setups. Only had to drill two small holes for the vacuum lines on the bulkhead fittings, everything else bolted straight up.

Using GTR piping setup with your stock manifold will be pretty crappy though. China piping tends to be 2.5" which suits your stock throttlebody whereas GTR piping is like 3.25" and the plenum inlet is a similar size (I have a custom GTR plenum with a Q45 t/b on the front so it suits the 3.25" piping).

You put a GTR plenum onto your RB20? How? How much was that?　Does it help at all? So I should look for cheap China R32 GTS-T piping or GTR piping? How can I do the piping?

The engine in my 32 is an RB25/30 (R32 RB25DE head so intake plenum bolt pattern is the same as RB20), I had a custom plenum made using the GTR chamber welded to stock runners.

If you want to use the GTR cooler then your best bet is using GTR piping and a forward facing plenum (search for KU Engineering) with a bigger throttlebody.

If you use the GTR cooler with stock manifold you will have to step from 3.25" down to 2.5" and run the normal "across the radiator" pipe that most aftermarket kits utilise.

I think it is important to note here that there are no pipping kits to mate a GTR cooler to a GTST.

Using a GTR intercooler WILL require some form of custom pipework.

My plan was to use GTR cooler along with a china 2.5" pipping kit ane minorly modify the ends that meet the cooler. Will cost alot more by the time you buy the GTR cooler and the question will be raised, why? Performance will probably not be notable at sub 300rwkw and from what Ive seen an upgrade will be in order before getting to 400.

Mike, just buy a complete front mount kit from Just Jap.

You'll be able to fit it yourself, as you don't seem to be a guy with a heap of knowledge about these things (no offence intended, an observation).

I run a JJR one on my tarmac rally car, has plenty of flow for 230+ RWKW (much more than you have now), and is the right price, with everything you need :D

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
