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.

Help

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.

My 2c.

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

    • You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.   
    • Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.  
    • I'm both sorry and thankful that you do that. 
    • 2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers. 
    • Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
