Hey all.

I'm about to start modding my car again and am changing my high-flow turbos for a couple of the new T28-10's.

While I'm at it I will be changing the intercooler from stock to a new Trust cooler.

I was going to go with the Trust Type 23 - 302x600x115 (3 core) however my mechanic adised I should be going

with the Trust Type 24 - 284x600x76 (2 core) citing that the larger cooler restricts airflow to the radiator too much

and that the Type 23 is good enough.

Experiences - Thoughts???

Thanks

i would tend to agree. 76mm is still quite a thick core. and going to 115mm will mean practically no airflow is making it through your intercooler and air con core to the radiator. personally for anything up to 350rwkw I'd be happy with the 76. if it's more power than that you're after then the big core may be a good idea, and a new radiator wouldn't hurt either :D

Would a clean undented fin 32 GTR intercooler be better than a 100 mm thick aftermarket core if its got fins that are dented a bit an kinda closed up doesnt leak but looks shitty an I think might be resticting flow a bit.

Anyone got dimensions of the stocky?

Might be able to get a good condition stocker cheapish thinking it will make a good stopgap till I can source a ARC or something

Been having some cooling probs so thinking the thick core might not be helpin

the reason there are such thick ones is for drag racing wher the sheer mass of the things is where the cooling happens. rather than relying on a volume of air going thu it.(still gos thru)

interesting note. on our race supra. it had a 700x300x76 cooler in it. 22 row. it used to overheat. so.. we cut it inhalf. to make a 700x150x76 core. 11 row. now it doesnt overheat and made NO DIFERANCE to inlet tmps on the track.

My idea of intercoolers has always been to get the smallest you can get away with for your application, the bigger the intercooler gets means more volume that the turbo's have to fill up with air before that air reaches the throttle body and hence worse response from off boost to on boost

I'm convinced T04GTR that most of your posts, while factual sound, are bashed out, while coming down off a heroin hit. Your English is completely "EnGrish" i love it.. keep up the good work!!!! :D

ARE can run some calcs of ur setup and come up with the right sized cooler for your needs. $90 for it, and u get $50 back if u buy one of their coolers (which are only $1500)

or if you're nice he might just do them for you anyway...

90mm ARE is sweet

a decent new jap one is only $1500 new, ARE are spin doctors.

We just replaced the 78mm generic tube and fin cooler one on cats car with a brand name 115mm unit and repeated runs on the dyno show the advantage of having larger cooling area, there is far less heatsoak after 10 or so runs. This combined with phenolic intake gaskets has been quite suprising.

you seem to love your jap 'brand names' alot dont you and your fast to beat down on the aussie gear :unsure:

hows the response changed of the car with the larger cooler?

well they may be the same money as a Japanese cooler but I'm willing to support the Aussie team at ARE

after all it's a lump of aluminium.

note mine's a tube/fin 90mm ARE made to order through discussions with them.

service means alot to me too.

i do because we get fed a lot of baseless shit..... a local guy in a shed struggling to make sales needs a good line.... do a bit of back ground work and you will soon find the facts behind the product, where it comes from and whether or not it is as good as the line you were spun....

as for response after a quick tidy up it was barely noticeable, actually far less than i had expected.

      Blue/grey smoke after idle

      By sunsetR33 · Posted

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.

      The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
