So the question I want to ask is who here runs a GTS-R manifold on a RB25 ? What turbo do you run, supporting mods ?

I have a GTS-R manifold thinking about putting it on my R34 Neo RB25.

I know its a big investment for not so much gains ( could be spent elsewhere ) but I just love the sound.

Hey mate,

The simplest way would be to source the standard T04 used on the GTS-R and the intercooler piping.  Although the turbo is a laggy old-school design, it will be a bit less laggy on an RB25.  If you are to go down the aftermarket turbo route, you will need to fabricate lots of stuff.  The manifold places the turbo on an odd angle, so both the intake and exhaust pipings will need to be fabricated, and probably changes to the water and oil feeds.  The compressor housing will need to be rotated.  Not trying to put you off, just show it isn't the simplest of jobs.

I put an aftermarket turbo on my GTS-R and had to get all the fab work done.

As far as sound goes, I found that the manifold didn't howl as much as first thought, but once I dropped some Tomei poncams in it, it wailed like a banshee.  Having said that, I have been in cars with cams and 6boost manifolds and the sound is very similar.

Thanks for your reply datberger......

Do you have any pictures of your fab ?

I also have an aftermarket dump pipe (short) to suit.

I measured the turbo side mounting plate on the manifold from what I have its a T3 which I though was different from the T04 ?

What aftermarket turbo did you run ?

Cheers.

Hey mate,

I'll try to dig up some photos of the fab work for you.  I put on a Garrett GT 2860R, basically the disco potato turbo that the silvia guys use, but with a T3 .63 exhaust housing.  It is good for about 300whp.  Too small for an RB25, but comes on boost about a 1000rpm earlier than the stock T04e on my RB20.

And yes, it is a T3 mounting plate on the manifold, as the stock GTS-R exhaust housing has a T3 exhaust housing mount.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
