As stated, you really can't.. you simply need the extra size to do it's job correctly

If you want a side mount your options are really limited to the R34 stock side mount but even then it's not that much of an upgrade, or the ARC sidemount which is said to be okay as an upgrade, and is able to handle a little extra boost but you'll find things getting hot if you push it too much, and with the cost of those you might as well purchase a front mount

Have you considered a turnflow style front mount cooler?

All the other side mounts have the inlet and outlet wrong for an R32 so you would have to take them off and re-weld them. The 2m of piping won't be doing your performance any harm but for tidiness a return flow would do the job. And yes water to air coolers work fine but a lot of money for no real gain.

What's your definition of max out?

I have both the ARC and Trust/Greddy SMIC units (the larger ones...they also made smaller ones but they're a similar size to the R34 GT-T unit and therefore are a waste of time these days). The ARC unit is slightly larger than the Trust one.

However, the ARC unit re-uses the stock plastic duct thing whereas the Trust one comes with its own metal air guide. Whether or not this has any difference on performance is hard to say. I would guess that the best setup would be the ARC unit with some custom ducting instead.

R32 GTS-t

Length: 205mm Height: 190mm Width: 60mm Volume: 2337cm^3
R34 GT-T
Length: 205mm Height: 220mm Width: 80mm Volume: 3608cm^3

Trust/Greddy:

Length 240mm Height: 193mm Width: 103mm Volume: 4771cm^3

ARC

Length: 240mm Height: 200mm Width: 108mm Volume: 5184cm^3

Anyway...as to how they perform...well it really depends on what gas you are using. A lot of the people on here get bad results with them because they are using 98RON pump gas. These things were made for the Japanese market and on the assumption that you would be putting in 100RON or better gas. I know people in Japan who have used the ARC SMIC with a HKS 2530, made 200~220rwkw, and had zero problems with detonation/pinging or heat. In fact, HKS' own demo cars for the 2530 (HCR32) and 2535 (ECR33) back in the day used SMICs.

YMMV. But if you want to try it, here is an ARC one on YAJ:

http://page18.auctions.yahoo.co.jp/jp/auction/w122908114

If you don't have access to 100+ RON gas but still want to make 200~220rwkw...then it would be better/easier to use a FMIC so you have more efficient cooling (and therefore detonation prevention) to make up for the lack of fuel quality.

If you do have 100+ RON fuel and you only want to make 200~220rwkw...then there is no reason why you couldn't use one of these. My friends in Japan were able to do this without a water spray kit, but I imagine in hot climates especially it wouldn't hurt to put one on. Cusco/Pivot used to sell one, but it's discontinued. You can make your own and buy the controller someone posted above. The Cusco/Pivot one is nice though because it comes with a perfect spray nozzle that really gives you a fine atomized spray over the IC. If anything I would see if you can find the nozzle and ignore the controller since it isn't as smart as the one posted above.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
