Ok got a S2 R33 stock as it is apart from boost gauge and wheels....

lookin to get a boost controller or something similar and wanting to know what i can safely boost it to

i believe it is round 12psi? but lookin to probably tune up 2 bout 10psi....is this ok on all stock parts?

if u can jus let me know it would be great

Cheers

if you are not running some kind of fuel controller like minimum SAFC you should only be running it up to 10psi anything over and it will lean out and be R&R i do believe

Yes, this has been covered more then anything.

But, don't worry too much about damaging the car. If your ECU is stock it'll rich + retard at 12psi+ to save the turbo.

A tune/piggyback means you'll need to be careful to keep it at a safe level. 12psi should be the limit on a stock turbo. For a track day even less.

Get a boost controller (search 'turbotech' here and on ebay, very good and very cheap) and a boost gauge.

If you don't care about money get an electronic boost controller.

Do a search, many opinions are better than one :D

i would look at doing your exhaust before going to 12 psi. the stock exhaust is very restrictive and provides less than ideal conditions for your turbo at high boost levels.

i'd say maybe 10psi on stock exhaust, if that. also, look at upgrading your intercooler to an r34 side mount.

yeah, im lookin into boostcontrollers...

but what exactly should i search for.....?

wont be puttin it up higher that 10psi on stock...plan to go up to 8-10 psi......

as it is even with 'high boost' (4500rmp or whatever it kicks in at) i cant break 5psi...i have a boost gauge and i cant get the needle over 5psi no matter what i do....?

Exactly wat GTST said add extra flow by getting a 3" for turbo back system (forget the switch for loud n not loud) this will allow the turbine to create more boost for your system. Get a single stage or dual stage boost controller to allow for boost adjustment up to 12psi at maximum. Also maybe look into r43 SMIC upgrade or if you want go for a FMIC there is plently of options to choose from. Pm me if need be matt, hame

    • 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?
