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.

i got pwr radiotor std clutch fan and shroud nismo thermostat 62 deg i think

rb25neo in r32 276.8 kw at the wheels and it runs too cold at 76 deg for cruse always in cold corection unless i thrash it then might get into mid 80's

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.

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.

      Looking for someone with a R34 front bar

      Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂

      new 1.5 LSD issues/concerns

      By Dose Pipe Sutututu · Posted

      Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
