Anyone suggest the best way to upgrade the DR30 intercooler?

Should I just fit a new frontmount or is there an upgrade available to replace the std intercooler with a better one while retaining the std position in front of the left wheel?

I'd prefer to keep the std look and avoid too much cutting but not at the expense of efficiency

Cheers

No upgrade as such, but R33 standard intercooler is good for about 300hp.

If you look at the pics on the now, my track car thread, the intercooler on that had the air con still intact & all that was lost was the headlight washer pump.

The inlet is on the bottom, that's why it's hard to see. I'm going to put it in the PNV and use a crossflow too.

I recently bought a Delta Fin Intercooler, they are lighter & flow better than conventional bar and plate construction. The one I bought is big, 600 x 300 x 78 & flows 1020cfm with a 0.2psi drop @ 20psi boost & good for up to 900HP. But that is for the track car.

600 x 300 x 76/8 isn't necessary for a street car, it's an over kill if anything.

My mate here has gone the smaller of the 2 china cores available fits in pretty nice and snuggly in between the headlights with minimal chopping

Where I have gone the larger, which to get to fit was a bit of a bitch. Welded 90 degree bends on the ends to get it in a little tighter with a bit more chopping necessary. To tell ya the truth I really should have just gone with the smaller option as performance gains would be minimal in comparison.

The ebay kit is the large version. It's 600 x 300 x 76 (24" x 12" x 3" old school) I think what Josh is talking about is approx a 400mm core length, but I'm amused as to why both are mounted with the inlet & exhaust at the top instead of the bottom where a large majority of the space needed to fit them is under the headlights on an Iron Mask front.

Got my car back from the panel shop finally and was checking intercooler space.

Not too keen to cut the hell out of the centre support so may look at a 600x150 intercooler mtd low down in the airstream.

Seems to me only the lower half of a 600x300 would work in a street car anyway

Another option is a Water-to-Air IC. I'm using a PWR core in place of the OEM x-over pipe (my car is an '83 RS-X so it was non-intercooled).

I've just upgraded my pump to use a Bosch unit, and am using the air-con condenser as the heat exchanger. The next step is to fit a reservoir of about 5L to increase the capacity of heat-sinking that the system can cope with.

I'd post photos, but it's all apart right now with the pump upgrade and reservoir installation...

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
