Thanks Joe. You run a racepace radiator as well yeah? Well to be honest, i'm happy to spend the money on a quality radiator for XX size and features that i need to effectively control the water temperature. The thermo fan vs clutch fan debate is kind of annoying. I think i'll stick with the clutch fan way unless i simply do not have enough room to accommodate it anymore. And with anything thicker than a 42mm rad, i wont be able to. 42mm is going to be tight as it is and i must confirm if it will still fit.

Ok i emailed both Racepace and Race Radiators. Racepace can supply a 42mm triple pass (N Flow) radiator that supports the shroud and clutch fan. They only do them for the R32 - R34. So an R33 item must be used with custom mounting. This is $550. They don't really offer anything bigger as they came to the conclusion a 42mm rad is adequate on high powered circuit cars. Racepace's opinion is that the factory clutch fan / shroud setup is better than any thermo fan even on a track vehicle. Race radiators offer a 42mm single row, 55mm 2 row crossflow and a 65mm 2 row cross flow. They do not supply a bolt in for the R31. Their recommendation is that the 42mm with the factory clutch fan and shroud is only suitable for street dutes. For race use they use the 55mm and 65mm coupled with a thermo fan without shrouds. 55mm unit is $750 and the 65mm unit is $850. So a bit of price difference and recommendation difference as well

No worries, i'll flick them an email.

Yeah i did find a post of yours about you fitting a racepace unit. But i was sure they didn't make them for the R31 so i wondered if you had fitted an R33 unit. So Racepace is comparable to other high end radiators? What is yours? Cross flow or vertical flow? twin or triple core? Are you using the clutch fan with i assume R33 shroud on your GTS-R? What size cores do they offer? The other question i guess is do i keep the clutch fan with a smaller core or go with a bigger core, ditch the clutch fan and shroud and go for a spal 16"er

Yeah, because there are no oil squirters to use in the first place...

Im not hell bent on a PWR no. But as far as i know they are one of only few if not the only place to get a direct fit to siit an R31. Im pretty sure an R33 unit will fit but it sits lower and needs new brackets made up. The brackets are easy but the sitting lower part is a concern. If i do end up with a thermo fan it will be a spal only. Does anyone know of other very good rads to suit an R31? Obviously a cross flow twin or triple pass would be a good option. Im fairly sure the PWR units are vertical single pass.

So back to radiators. PWR do a 42mm and a 55mm radiator to suit Skylines. The 42mm is designed to work with the factory clutch fan and shroud. The 55mm will only work with a thermo fan. They recommend a thermo fan on one side of the radiator with no shrouding. They supply brackets to do this. The 55mm rad they do is designed for track use only more or less. I think the idea of having no shroud and a single fan is to try and promote maximum air flow while the vehicle is in motion. The fan is to help cooling at low speeds/idle. Is this theory correct? My question, whats the ideal way to go?

Why not just buy it from Kudos and if it doesnt fit its their problem for incorrect part listing..

This requires liquid CO2 to cool the fuel. Not an ideal fuel cooler for most. This is suited to drag racing more so i think.

This. When fuel gets hot it causes a vapour lock in the fuel system. Pressure pump starves - car runs like shit, stalls and possibly leans out under load. Fuel cooler is also good to help prevent knocking.

They should be replace with brand new items when they start to become brittle yes. But no one ever does.

To be honest mate, Its not worth pulling out the engine to fit just a head drain. If the engine was built properly with oil control in mind then you technically shouldn't need a head drain. I have just finished building my engine with two head 'drains'. One at the rear which technically isn't actually a drain, its a breather. And the other one is on the exhaust side of the head between exhaust ports 3 and 4. I am a bit on the fence as to whether the rear drain actually doesn't anything or not, but for the low cost of installing one and the fact i was assembling the engine i was able to easily do it on the stand. But it really isn't worth pulling the engine to fit a rear drain. PS, if you really want to do it, get a Nitto drain fitting as they work with the RB26 lines at the back of the head much better than any others.

This is my fuel cooler. Not an awesome pic but you get the idea. Its a Setrab core with dual spal fans. Its fitted inline with the return line from the rail to the surge tank. Fuel temp sensor will be placed just before the cooler. I plan to make up a duct from the rear quarter window to the front of the core through the firewall using some sort of flexi hose. It should be pretty effective at taking a reasonable amount of heat out of the fuel. I did NOT want to mount it anywhere under the car where it could potentially get smashed.

363rwkW is a lot of power from a GT30. Many many people swear it cannot be done. Good result. Whats next, GTX35R?

R34 balancer is different to the R33 R33 runs a 3PK power steering belt. R34 is a 4PK power steering belt. Offset on the power steering is different as well. R34 visually looks different as well. If someone is looking for an NEO one, i have a brand spanker for sale Fuel system is looking good dude. Nice and stealth!

The water piping for an RB's oil heat exchanger enters the from the rear water exit for the block (also the feed for the heater) and exist the exchanger into the water pump inlet post thermostat. Here's a question, what location should we be getting our oil temperature from? Should we be getting it from the bottom of the sump or post oil cooler as it enters the engine's main gallery?

So if its not a CP piston issue then buy CPs... Problem solved. Most manufacturer website lists every single piston they make in a cstalogue.

People have answered your question. I have CP pistons so id like to know what happened. This forum is about helping people. You asked a question that has been answered and we're asking a reasonable one back. Is that not fair?

Id also like to know what supposedly happened to said CP pistons.

Oh i do, and i have. Now he's just annoying.

Can someone please just ban this oxygen depleting nuisance and block his IP address.

Some single turbo setups are very responsive over a twin set up. Some are not. Kinda like some people are naive, stubborn and arrogant and some people ard not
