Hey guys

Have been thinking about getting my car on to the track and two questions are burning a whole in my mind.

number 1 - is it worth replacing the stock radiator??

My car makes about 205 rwkws @ 13psi, so its not hugely modified, yet its not stock either. I have been looking at the cooling pro radiators from just jap which are alloy and 60mm thick. They retain the factory shroud and id just be using the stock clutch fan.

Do these perform much better if at all than the stock r33 radiator?? and also is it even worth replacing in the first place? as my stock radiator works perfectly fine to my knowledge anyway. i just dont want the car overheating.

and question 2 - oil coolers.

i have been looking at the cooling pro ones once again from just jap, they seem like pretty decent quality?? (one of the 11 bar kits including filter relocation)

Also since i have bugger all tools at my disposal at the moment, how much would you imagine it would cost for someone to fit an oil cooler for an r33 series 1??

my car is 95% a daily driver, im thinking about having a few spurts on the track when the oppurtunities arise, i really just want piece of mind about the temps in the engine bay if i do a few hot laps.

same kinda deal with the oil cooler??? any money i can save will be going towards a turbs upgrade and coilovers as well :D:(

i guess best bet may as well be just bomb it round the track a few laps and see how high temps get. next track day around my way is in december, so the hot weather will really test it!

Oil cooler is good to get.

Are you running the stock turbo @ 13psi? If so, for track you really need to back it off.

Otherwise you will kill it just due to the heat that track brings, the rear wheel wont take it for long at all.

Some people's have died on their first track day out :D

What are the temps of the oil that people reach out on the track?? I personally have never seen over 88degrees in my car.

Higher than 88 thats for sure.

10-20mins on a track sprint is nothing compared to even a spirited squirt on the street...

Given brakes probably wont last more than 3-5 laps before requiring a 'easy' lap or two before getting up it again...

      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).

      EMU Classic. For what I need it to do I see no reason to upgrade. Link and Haltech would both cost an extra chunk of money for a lot of unutilized features
