Hey all, Im looking at putting a new cooler in my car.. Cause mine is looking pretty shot..

Im looking at putting a 600x300x100mm in my car.. the turbo will be running around 16psi when its all back together..

Its a R33, Minor mods... Power fc, Cams gears, 3" straight pipes with a varex, And a FMIC thats not looking to healthy

My only problem is i have heard.. with a bigger cooler you loose boost pressure if your running low boost, but my issue is.. what do you call low boost?

And is this just a myth?

I would personally go a 76mm cooler core, 100mm is way to thick. Also if your have a real thick intercooler, its harder from air to pass through and your radiator will recieve less air and then may have overheating problems. Save your money and get a 76mm core, you will probably notice a bit of lag with the 100mm core, because there is more area to fill, it takes longer.

Intercooler core design is the bigger issue - whether it is a tube and fine or bar n plate. Do a search for the differences.

When i was upgrading mine, i looked up and found that the tube and fin design is more effecient at cooling the charged air - however something to do with how it flows through the tank which affects radiator effeciency. 76 or 85mm wouldnt really make that much of a difference.

IMHO - I think that a 76mm tube n fin design would be more effecient then a 85/86mm bar n plate. Im using a tube n fin 85mm HDI fmic and I dont have any overheating issues at all.

Best to do your research before you think of buying anything. Good luck! :down:

Nope....tends to go bang with anything over 14-15psi being constantly pushed through it. Hi-flowed with a steel turbine wheel sure, but ceramic will simply discintegrate & part ways with the turbine housing & disappear into your exhaust somewhere....

Back to topic, get a Greddy, HKS, ARC, Blitz, Nismo, etc....76mm cooler.

If you are on a budget the cooling pro ones from just jap also do the job fine.

If you are not running at least 20PSI or higher then there is not point and a waste of money to buy a 100mm cooler.

As a comparison, many GTR owners out there are pushing 350AWKW with the stock cooler no probs!!!

Why would your car need a 100mm if its pushing no where near that? :P

Check out the SAU sponsers as they look after the members with good pricing.

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
