Im buying a R34 GTR soon. I want to get a compression test done to make sure all is sweet with the motor (and because as you all know, the "TRUE" klms travelled by the car is nearly always a mystery with these cars.

Do NRMA do compression testing if I send them to the car or is this something that has to be done at a workshop?

If NRMA dont do it, would Croydon Racing Developments or someone like that do it?

(please excuse my ignorance on compression testing)

Thanks

my opinion, if you know what compression your looking for in each cylinder any mechanic can do it, no need 2 pay someone more for the same thing. As said above just make sure they have a good quality accurate guage

just my 2 cents

b4 I bought my car, I got it compression tested by Nathan @ grey imports. The seller was happy to take it there, it didnt take long. I just payed over the phone via card and they called me up and told me the result. I used this guy as quite a few on SAU have used Nathan to do compression tests. FYI it came up with 165 on 5 cylinders and 162 on the one, which was a really good result, Nathan said it was a well looked after car. Let us know the results

EDIT: it cost $100

    • 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?
