Well I ended up getting a Prestone back flush kit and radiator cleaning solution and flushed quite a bit of gunk out of the system. I have flushed the engine before installing but I guess over time more loosened and was clogging the coolant system. I also used a bottle of redline water wetter and I can happily say at idle I can get temps down to 80c with just one fan.

Thanks for all input!

I need to do this as well. I have/had quite a bit of rust in my system. I flushed most of it out when I drained the radiator, but I can't get to the block drain bolt. So I just kept flushing the radiator.

Are you in the USA? How much did that Prestone flush kit cost?

can people put up there power figures also, because its alot harder to keep a high power car cool than stock power.

depends, is power relative?

my car is only ~135awkw thru an auto, so prob 150-160rwkw in a manual r33

but my old datto had 100ish rwkw from a 35yo(rebuilt) "standard" 1.8, it ran at 72deg all day every day, engine fan, no shroud, re-cored stock radiator from what i could tell, and it was bored/stroked/ported... so you would think with the higher tech stuff it could be kept cooler? just get a vipec and run cycle idle :cool:

I hit 100 degrees the other day giving it stick and holding, it in the middle of the day (was a bloody hot day). I'm going to look into a decent PWR radiator or something along those lines soon. This was the first time it has hit anything over 92. However i don't have an exhaust manifold heat shield on there at the moment cause i havn't had a chance to get my new one made yet, so this could be contributing to under bonnet temps.

Note to self, "Townsville day heat plus giving it stick with 450BHP, bad".

The kit and flush solution was about $15 from pepboys.

I would suggest trying again to remove that block bolt, I've found that a lot of gunk accumulates back there and the only way to remove it is to remove the bolt & flush.

One more question before I attempt this tomorrow (I just installed a FMIC and now my temps reach about 195F/90C):

When you did the flush, did you remove the block drain plug? I tried using a cordless impact wrench, and that wouldn't even work.

Take it for a power flush and rod the radiator.

Involves disconnecting the heater pressure flushing heater and block.

If you do run an engine flush without a pressure flush grab a stocking and shove it over the top and bottom rad outlets to catch any crap.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      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

      Coolant leak?

      By Duncan · Posted

      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
