I've had my r32 GTR for nearly a week now and i'm still getting to know the ins and outs of it. I've just managed to get the boost gauges working and have discovered that the car is running with 13 psi boost. The guy I bought it off said that it had standard turbo's running standard boost. I've searched all over the engine bay and I can't see any sign of a boost controller or bleed valve. I had a look at the turbo's and they have got Garrett on them. Am I right in thinking that standard turbo's are IHI jobbies?

The car has a full aftermarket exhaust system including hi flow cat and pod filters. Does this amount of boost sound right with these mods without the use of a controller/bleed valve? How many different model Garrett turbo's are there for the gtr?

Where's the restrictor and how can I tell if its been removed?

On the driver's side suspension tower, you'll see 2 small black hoses going into a silver cylindrical gadget.

On one of the hoses there may be yellow band, this is where the restrictor is placed. Whoever did the job may have just cut the restrictor out instead of kneading it out, so you may not have the yellow band.

In any event, this is where it goes.

Yeah I've seen this. If thats the case then the restrictor is still there.

Squeeze the band to see if there's a solid brass ring in it. The band may be there but the restictor may also have been removed.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
