Hey!

I want to get more out of my FMIC upgrade.

Usually people would go with 600X300X76 core, but what if I go with 600X300X100 or 110 with better tanks ? Most of the 600x300x76 core come with square tanks, that don't really aid in air travel and sometimes even help with pressure drop.http://www.are.com.au/feat/techtalk/tanks.htm

If I go with a thicker core what benefits will it have ? What cons ?

Now about the core design. The most used one is bar&plate design but what about tube&fin or delta fin ? What are the advantages/disadvantages of either design and what is best suited for street/track applications ?

Thanks!

If you are looking at 250rwkw of power, it might be wise to think about HEAT.

the HEAT generated spinning up that sort fo power.

will your stock finger thick radiator be up to the task?

possibly just.

but what about when you add a 100mm thick metal thing in front of it?

how about the extra capacity of the even thicker intercooler and it's effect on throttle response?

you're right about the end tanks on the generic $200 jobies.

they are not that great.

having said that, if I were in your shoes, I would be looking at an R33 GTR OEM intercooler with custom piping.

People have easily got over 300rwkw with them.

SydneyKid has posted about the pressure drop and temperature variations on his tests on this intercooler.

it came up trumps up to about 300rwkw.

AND, as an added bonus, it is tube and fin, which means plenty of air flow through the fins to cool the poor little pissant radiator behind it.

A GTR intercooler will do the job for you.

There are plenty of cars, as well as GTR's themselves, still running the stock intercooler setup on over 250rwkw.

I just met a guy the other day, off these forums who has his GTR tuned to 285KW@ all 4 wheels, and has retained the stock intercooler setup & plumbing.

Those intercoolers are also a quality built tube and fin design as GTST said, cant go wrong for what you pay.

For the whole "core vs core" thing, please search.

Pros/Cons of each are in a large thread already on the forum that wont make it to this thread as people generally dont post the same thing half a dozen times :3some:

OK. I got 52mm radiator already. And I got a plate and bar 76mm thick FMIC already. Just wanted to make everything safe. How thick is r33 gtr oem intercooler ? And what if I get a copy of it ?

I think the stock GTR cooler is about 65mm thick.

You're sorted with what you've got already..

I wouldn't bother..

the way you posted, it sounded like you had stock gear and were looking for an upgrade for future plans.

hey guys,

i currently have all the stock gear on my R32 GTS-T and am looking to upgrade a few itmes. i'd like to know what ur thoughts are on the Just Jap GTR replacement tube & fin intercooler they offer.

Never heard of "COOLING PRO"..

Put it this way.

I'm sure it will do a better job than the factory R32 GTST item.

but if I could get an R33 GTR intercooler for the same price or better, I would get the GTR one.

it's been well and truly tested for flow, cooling, pressure drop etc.

Having said that, I've used a generic just jap style bar and plate china intercooler on my S14 with regular mods and it worked fine.

it's up to you what you want.

yeah, it seems to be Just Jap's new intercooler brand.

i know the chinese made coolers would do the job, but not sure how well they do their job.

also, the thing is, i have a complete Rb24 engine in parts in my garage along with a Trust T67 kit which i'd like to put on the car one day so i'd like to get something that will also work with a higher HP range.

Also, i'd be happy with a GTR cooler but i haven't been able to come across one which is why i've been looking at the Just Jap GTR replacement cooler.

I see.

It seems you've spent a bit of money on this rebuild.

I wouldn't skimp now on an unknown part.

Up to you.

Maybe put up a wanted add here and maybe on Performance forums for an R33 GTR cooler.

well, not really.

i bought the car with a heap of spare parts as it used to have this RB24 & Trust T67 kit running in it before i bought it.

the car is currently running in complete stock spec, but if i upgrade anything i will do it with the outlook of eventually having the RB24 & T67 running in it again, so i want to do it once.

i'll check PF, thanks GTST.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By dbm7 · Posted

      For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...

      Exhaust silencers/varex exhausts

      I’m also conscious that e85 is slowly being phased out. Not all United’s have them anymore. Can’t take the risk of being low on petrol and assuming the servo will have it.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      MR HAMMER has said his piece. Painted up to avoid Rusty Rusty. Actually lines up well. (i.e it lines up the same as the unmolested GTR guard). Turns out the GTR Strut brace does foul on the bonnet vents ever so slightly. May need a little bendy bendy if intended to keep using with a strut brace. So spacing it out to clear the FAST102 is not an option. Annoyingly, the bonnet vents also foul on the heater lines running over the engine. Given this engine does not EVER require a heater, a delete loop is going to be used. Don't worry, the defogger uses the AC. The heater is basically "Do not use the aircon and turn the fan on". It will still be effective, I promise.... once I get the system regassed... Will have to revisit with unvented bonnet I suppose, and suitable strut brace. There's plans to do this and other things tonight and bleed brakes (there was a weep) and put the bumper back on, and take Good Friday morning - Because troubleshooting on the side of the road limping it home at midnight tonight is ... not very smart.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      Thank you all for you assistance. I contacted Nistune regarding the support for the RB20DE along with my ECU Code (23710-10U00). They do have a map for it and added the RB20DE as a purchasable option now as well. They also added Malta as a Billing and Delivery options as this was missing. I was honestly amazed at their quick response and action, it took less than 24 hours. I also looked again at direct fit options for injectors, just in case I were to replace them. DeatschWerks seem to use a Bosch EV14 base and makes ones that fit mine at 440cc lowest, but also have 550cc at the same price. I tried looking for other direct fit options and managed to find one (also Bosch EV14 based) which includes a plug and play adapter on ebay. Did a small test with a Noid Light on the troubled injectors and all seems good, so they are pulsing properly electrically. One weird part is that they are missing on the same two cylinders as before I got the injectors cleaned. Mechanic also found this weird as he did not label the injectors and it is unlikely to have the faulty injectors be installed in the same cylinders.
