been reading a few posts about gtr bovs..seems to be a few dif opions...

tested mine yesterday with an air line and tee fitting with a reg to put air on both sides of the bov at the same time to see if it holds say 20psi or more...

seemed fine at even much higher than 25psi...so whats the benifit of after market bovs like the greddy type r etc....

is the air flow of bigger turbos the reason they start to open at higher boost levels...

cheers..

Yeah Ronin, that's the Trust 16 row oil cooler kit, I learnt the hard way...

Sent it back to Japan and got the HKS 16 row oil cooler kit which is mounted on the passenger side inner fender... only to find out that it doesn't accomodate for the series 3 xenon headlights...

I hate oil coolers!!!!!!!!!!!!!!!!!!

Hey JAGR33, I thought the Trust mounts in the LHS (passenger) fender? Maybe just for R32.

Got me worried now. They have one that they say mounts 'horizontal mount' - does anyone know what that's about or where it is exactly? Sorry to hijack, but I want to know if there is a Trust oil cooler kit that fits with the factory BOVs :P

Ronin 09- yeah the kit I got was for an R33 GTR, and it was definetly mounted on the driver's side, ask Gerald he was there when I tried to fit...

Horizontal mount is underneath the radiator and the cooler faces down towards the ground, and is fed air through an air dam.... Don't know if they are practical though....

Emre- the hoses cleared the back of the headlights, was a very tight fit... The main problem encountered was where the oil cooler core sits, one of the fittings that goes into the cooler itself was in the way of the little black box bolted underneath the xenons to run the gas discharge, was a big headache!!!!

Ended up unbolting the little box underneath the headlight and relocating a little lower so it wouldn't hit the fitting...... Got there in the end!!!!!!!!!!!!

Emre- yes the catch can was a problem too, but where one of the fittings goes into the core itself is pretty much directly under the passenger side headlight..... Well the xenons have a little 'black box' which controls the gas discharge, this was hitting the fitting on the oil cooler core so had to relocate this little box.....

Bit hard to explain......

Does anyone know if you can let the stock gtr valves breathe straight to atmo?

 

I upgraded my cooler & therefore couldn't put the recirc piping back in so I changed the valve. Still got the stockies so I would put them back in if I could get away with it.

I don't see how this would be a problem in terms of boost leak (unless they have the little bleed hole like a GTS-t BOV). It should only really affect stall and mixtures.

    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it. 
    • Not yet quite as bad as what we've seen a Jim Berry clutch do in an R32 GTR though when it decided to cut a chassis rail in half... Still very very gnarly and a great reason to avoid.
