Hi all , I see many threads on intercooler upgrades to R33 and R34 single turbo Skylines and I'm interested in exploring the topic but doing things a little differently .

Firstly my GTS25T currently has the R34GTt intercooler because it was easy to do ie it just about falls in .

Secondly I'm not looking for a million Kw and I don't want to overkill in this area . The turbo I have to fit is a HKS GTRS and something like 240 odd stress free Kw would be fine for me .

I don't want to go down the road of non standard inlet manifolds or extra pipework in the engine bay . I also don't want the full front mount with its considerable length of return pipe .

Now of late its impossible not to notice the diesel commercials and 4WDs clogging up the roads and the vast majority of them have intercoolers nowdays . We have a few utes for getting around the yard at work and I'm always trying to see if their intercoolers look like they would fit in the unchopped nose of an R33 .

My train of though is can you fit an intercooler of at least twice if not a bit more than the core area of an R34GTt into the near radiator side of a R33 . While this may sound a bit lacking from memory the twin turbo Z32 300ZX TT's made 209 kw and more torque on paper than an R32 GTR and they from memory used two intercoolers of possibly R33/34 25T dimensions .

I will never race or drag my car and all I need is enough intercooler capacity to not form an air restriction or heatsoak in the 6-8 seconds of full throttle use that is usable on public roads .

I'd like some bang for buck here not because I can't afford better but because I don't wish to overkill/overcapitalise with this car . Its also a challenge to find some hopefully low cost but adequate OE intercooler and have most of a car look as factory as possible . Less eye candy for rev and you protection officers to ping you for .

Does anyone have access to a light truck wrecker that could measure up some of these intercoolers ?

Cheers A .

PS please don't come back sayng just fit a JJ return flow because I'm not interested in going that way .

Ideally an intercooler with its inlet and outlet facing the same direction could be good because it could be fitted with its inlet/outlet facing the nearside to keep the plumbing short .

All the best, I'm all for innovation and doing things differently...but I am against ignoring common sense. Don't you think if it could be done and for cheap...the rest of us would have done it? It's like asking us to tell you how to do something that we didn't know how to do for ourselves.

The best you can do for that power level is try and find an ARC side mount...but nothing will beat a front mount on a Skyline by nature of how intercoolers work...a good design is important, yes...but surface area of the core itself is the most important factor, given it's air that's cooling it.

FMICs aren't illegal...why wouldn't you just get one?

Something like this but a bit bigger maybe?

A vertical flow core with tanks top and bottom would be what ur after.

I'd go a small conventional FMIC (around 500x250x70 or similar) with inlet/outlet in the middle facing 45 degrees backwards then make up super short custom piping and a 315 degree bend straight off the throttle body and going diagonally down to the driver's side from there. A 2.25" hot pipe and 2.5" cold pipe would be heaps.

the problem you will have will be heat soak with smaller coolers , the smallest diesel intercooler i've seen was on the '05-ish mazda bravo/ford courier . if i were you i'd be scouring yahoo auctions through import monster or something for an arc sidemount if you definately don't want a front mount .

I too had a yearning to try something a little different disco, started when i was fitting a normal front mount but didnt want to chop up my series one bar..

After a lot o fluffing around and some good help from Scotty, "Frankencooler" was born looking something like this

Its pretty stealthy once its all together. It works well makes 240kw and is very responsive, but is only possible if you are willing to lose aircon and f**k around fabricating stuff. I am keen to do a FFP as well for even less piping when the funds exsist :)

Before this I was toying with the idea of a vertical type cooler as well, there was one i found was about 500 wide by 300 high with tanks top and bottom, (I think it was from supra actually) so you could hook the bottom one up like you would a normal FMIC but you would have to pipe the top through next to the radiator which would make it really short as well. I was also considering the Gktech one that Brad suggested.

Only thing i can suggest is keep scouring ebay cause all sorts of weird coolers pop up there, and keep your imagination open, you'll need it

How do you survive Aussie's 40C days in a traffic jam? :whistling:

I've seen a couple of MR2 trust cores on yahoo auctions come up quite cheap lately.... they are very thick and are usually placed on a 'side' air inlet. Most of the MR2 guys get 250rwkw out of them before they start chopping into they're boot areas.

I'd be tempted to grab one and re-configure the end tanks for a side mount install... Or find an ARC side mount upgrade...

If you go side mount just put alot of time and effort into getting air in and out, maybe a thermofan on the back of it and/or temp activated water spray onto the core. If you get a good core, restriction isn't going to be a problem... it's just the heatsoak.

There are also a heap of W2A heat exchanger options out of the US. Pop the core in where the side mount usually is, hide the pump behind it, add a 1lt tank after the radiator (just to add volume to the system) then bang the bigest- thin radiator (painted black) behind the front bar.... hell, you could even add a little black ice bucket for track days/summer etc.

Cheers

Find someone capable of tidy allow welding and turn your R34 side mount into a water to air unit.

It will bolt back into place and look great.

You can also buy a cheap alloy rad to suit a civic from justjap, have your alloy dude mod the in and out pipes to have the water flow and buy a 12v water pump.

The civic radiator is half size and will be very easy to fab behind the rear bar, paint it black and no one will pick it.

Like this (although the 100mm version would be better):

http://www.skylinesaustralia.com/forums/topic/353819-fs-er34-arc-smic/

yes before my original reply I sent disco a PM with a link to a $280delivered HKS r32 gtst intercooler to match that ARC unit.

on ebay aus if anyone wants it

Hmmm ahah i don't know if this is relevant :). But The previous owner of my car had a little bit of an ingenues idea. he took the spray portal for the rear window and transferred it above my front mount. So when i trigger for it to release water there it actually sprays it down and in front of the inter cooler.

Sid

Idea is clever but it's been around for a while...I saw the same thing done on a television show 5 years ago lol^

Wiper water sprays come on a bit thick and use up water a bit quickly...better off finding a finer nozzle sprayer and putting that on the hose instead. Something really misty would be good...even two of them.

while where on the subject, Has anyone seen my windscreen wipers, i took them off to paint them now i cant find them anywhere :unsure:

LOL what? :blink:

On the subject of "I screwed up & lost something..."

Has anyone seen my yellow cap for the reserve coolant bottle? I must have forgotten to tighten it up after topping it up & now it must having fallen somewhere on the road while driving! :wacko:

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out.
