is a custom 600x300x90 cooler 2 big for a stock r33 turbo?

some would say yes some no, id say no. In rev 210 post of doing a 13 from a stockish r33 he feels the stock cooler to be more effective because you lose less boost though it than a larger cooler. I think a cooler intake temp may be more beneficial as when you mod more you keep getting gains from it.

What kind of power are you looking at achieving would be nice to know. If your just going to be dealing with the stock turbo im guessing close to 200rwkw? If this is the case then I would suggest IMHO going for something a little smaller (600 x 300 x 65 to 600 x 300 x 75 in size) as the larger core in question won’t really provide any extra benefits when dealing with the stock turbo, in fact it will have a greater adverse affect on overall engine response. The diameter and length of the intercooler piping will also play a major role in determining how much it will affect engine response.

If you only plan on keeping the stock turbo for a little while and will be looking to upgrade to a bigger item in the future then it may be worthwhile going for a 600 x 300 x 90 sized unit (depends in the end what power goal you are looking to achieve and any future upgrade you have in mind). Otherwise, if the stock turbo is all your going to have then I would go for something a bit smaller, as i have suggested above.

Just my 2 cents, hope it helps…

Hmmm, im not sure if that is why he kept the stock cooler for so long. I was under the impression that the stock intercooler would actually have a greater drop in pressure than a well designed larger item (but I guess the extent of this would differ at different boost levels). From memory he was boosting somewhere around 10-12psi, a sensible level for the stock intercooler. I thought it was Rev210’s intention to keep the stock intercooler to retain the greater engine response from a smaller cooler (shorter length of intercooler piping and smaller volume of core). Could be wrong though…

Gloof, I had a similar question to what you were asking before I decided on what sized intercooler I was going to buy. Here is the link: http://www.skylinesaustralia.com/forums/sh...ead.php?t=36533

The link Meshmesh pointed me to and SydneyKids response were both very helpful.

Hope they help you too.

i would htink at the end of the day you are removing the stock intercooler and replacing with one that flows better and has a smaller pressure drop. the amount of 'lag' that people generally refer to that comes with an aftermarket intercooler and piping is something so small that i would render it irrelevant.

get the cooler mate...

While on the topic i also have a similar question.

This is my set up.

Rb30det.

*power fc.

*gt3040 (600hp)

*standard Rb25 inlet manifold.

*high mount exhaust manifold.

* water injection (maybe)

Looking for 300rwkw.(1200kg car)

Will :600x300x76 with 3 inch inlet and outlets. flows 381 cfu. be good enough.?

Or should I go: 600x300x100 with 3 inch inlet and outlets.?

  • 2 weeks later...

My first FMIC was a 110mm thick unit to make up for lack of height.... It had major heating problems for the radiator.... My temp gadge would always be up around the high area....

New skyline got a 645x350x75 custom made and this worked a charm... Although it covered the entire radiator it was no where near as thick....

Current skyline..... Dont even have FMIC on road.... Have interchangabe piping for dyno.... But it runs too hot as well in summer.... its a 82mm thick....

I wish I wish i didnt kill that fish (had my last one stolen)

Point of my story... 3 skylines... 2 the same pretty much, and very different in performance...

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
