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.?

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...

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
