The problem (knock/ping) seems to be a single piston issue. We suspect a blocked injector or two. The afr's are super rich as I have previously dialed in more fuel to cushion any potential damage.

The result was a ping at about 4700rpm that prevented us reving it any higher.power: 230 rwhp - afr : high 9 with very little timing advance

170odd rwkw with 9 a/f ratio?? so ur car is a freak then!:D

Dave,

230rwhp (172rwkw) @ 4700 is bloody impressive! Given that peak power isn't till 6800 stock. If you've dialed the HKS cam gear for more top end then the peak might be even higher?

My estimate of mid 190rwkw is lookin' good :mad: It might go even higher!? Especially when you're running conservative timing & nasty rich.

While on the A/FR's, 9:1 isn't very healthy @ all :) You might have dialed in a little too much cushioning! Not quite as bad as too lean, but still not good.

Yepp, just as we thought, Rev's got one of those freak 1995 cars :uh-huh:

It's good to see that the ping issue 'shouldn't' be anything major.

Are you getting them cleaned using the ultrasonic bath way?

Once you get the ping sorted, and back for a re-tune, I reckon you'll see your 12 second pass :uh-huh:

Well done

It's not a freak car.

The first dyno it ever had (over 2 years ago) showed 180 rwhp odd on a dyno day with other cars and whilst a heathly figure it wasn't the highest.

the mods and tuning I've done are responsible for the power and considerable torque it's making (afr's uptop aside).

Mine's a 95, but it's no freak, hell I can't even pull the 1/4 in less than a 14 right now... so bleh!

considering dave ran a 13.4 without the AFC, i still cant see what i'm doing wrong...bleh!

So let me get this rite? 170rwkws at 4800RPM????

DAIM.

Pretty respectable figures considering engine mods are turbo back exhaust, panel filter, thermal wrap, 10psi, cam gear, afr of high 9's (untuned s-afc), and a little advanced timing (did I leave anything out?).

I'd be happy with that, that's for sure :D

Most people get less than that with a 'professional tune' at a workshop :)

Rev - are you getting the injectors clean by an ultrasonic bath?

Cheers

    • 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?
