Just when I get things the way I wanted them, it's time to move back to the US from Okinawa! I will be stripping my car down the beginning of Sept. to ship back all my goodies to swap into a USDM S13. I'm going to Albuquerque New Mexico from here! Anyways, here's a few pics of my setup. Details to follow...

I bought this car BONE stock 3 1/2 years ago. It's gone through several series of upgrades over the years & now sports a Full-Race GT3567R (GT35R with Full-Race T67 HO compressor) on a stock internal S13 blacktop with 1.2mm Tomei HG, RAS, HKS 264 cams & gears, "Freddy" intake, 1000cc injectors, Q45 TB & much more...Using an OS Giken Triple plate clutch with full OS Giken Crossmission & a Cusco 2-way with 4.3 gears. I have another SR we just built up with a fully ported head, solid lift Tomei cams & all forged intenals...going to add water/methanol injection & crank up the boost to see if I can hit ~600 rwhp, which shouldn't be a problem at all with this turbo!

Very Very nice car man. Shame that you have to tear it apart but hey at least you get to keep your stuff. Just have to transfer it all over to a nice clean body!! Good luck and while your over in Japan say hey to my Cuz for me. Her stationed somewhere over in Japan.

Thats an incredable car. Its to bad you can't import the car as it is and get it legal. I am sure you have looked into that. But you have done it once you can do it all over. You will just be sitting on the other side. Goodluck with everything

I'm severely restricted on weight for my shipment back...it's NOT cheap to get this stuff home! I wound up paying ~$650 for my Koukis new, with getting the center piece & lower piece painted...Definately keeping them! The hard part will be tearing it all down to be portable enough for one man to lift each box...It really makes me sick, after I add up everything that I put into everything (I used very few used parts, almost every item was new!) I was tempted to try to sell it but I'd never get enough out of it & I'd want to make another back in the US, so it made more sense to keep all the parts I've already got! I will be selling the body to a good friend who's dropping in his built RB25DET combo. Here's an older pic of the interior, without my newest Recaros or Power FC installed...

every time i see a thread like this, it makes me want to join the navy. you guys have ridiculously nice cars. i'd love to have a sick 180 like that, and drive on japanese roads, and pull japanese girls left and right just for being a westerner. what do you even do over there besides be the coolest motherfucker on the island? :D

Not in the Navy! I'm in Air Force Special Operations...Yep, JDM women are pretty nice...Here in Okinawa however, they are MUCH more leary of us than mainland Japan, due mostly to the large number of incidents in the past here by GI's...This place is kinda like a Japanese Jamaica...they are a lot more laid back in certain ways & there's a lot of scuba & watersports here, since it's a semi-tropical island.

US DOT has made it damn near impossible to ship a car back legally...I won't get into all the details, let's just say even though I have the entitlement to ship back one car at no cost to me (for shipping & duty free) I still can't get the car into the country since it isn't on DOT's list & multiple attempts to do it legally through a registered importer have failed.

Now I just need a decent S13 hatch to daily drive once I get back, until I can get around to swapping everything...

Nope. They've come down HARD on the show car/race car exemption. Plus you have to export it back (complete) after 2 years at your own expense even if you did get it in this way. Bullshit! It really pisses me off, first, getting stationed over here, we can't bring any car newer than 1976 to Japan. Then, after being forced to buy a car here, you can't take it with you unless it's 25+ years old...and let me tell you, Okinawa will reduce a car to rust with a quickness! You RARELY see any cars older than ~1988 driving around anymore, so nice older cars are VERY expensive! Of course, we can't possibly make an exemption for our people serving overseas...you just have to take it up the butt & go into debt everytime you get orders to/from Japan...thanks DOT!

Beautiful car :1bowdown . I just got out of the air force in april, I had Japan on top of my dreamsheet for 4 years!! You lucky SOB. Well it sucks you have to take it apart but good luck in gettin all that stuff over here and into your new car.

Not lucky...it took me 10 years of trying to get here, and I had to volunteer for Spec Ops to get it...a LOT of hard work, not a lot of luck! Now I have to go to the schoolhouse to teach the next generation!:crazyrant Anyways, I would love to stay, but the AF says I have to go...if I want to make it to my retirement (4 years) I need to do what they say...for now.

Not sure what you mean by "ect"...

Dynos are a nice tool, timeslips are better, as timeslips don't lie & can't be "swayed" by an operator. Certain types of dynos can give very different results than others, so although it is nice to see around how much you have, even a dyno can be inaccurate. We had one place here (that is now defunct) that had an awful lot of "500HP" cars (with dyno slips to show) that would get whooped up on by similar cars with only~350HP... Unfortunatley we have no quartermile track here on Oki, and the best there is to legally offer is a 150 meter race (an eighth mile is 200 meters, quater is 400) that happens maybe 6 times a year, provided it doesn't get rained out. I am going to give a dyno a try this weekend, provided I can get in this short notice, but the car is going down in 2 weeks to get stripped for sale/parts shipment.

My mechanic & I went out tuning last night for a few hours & got this thing about as good as we're going to with it's current configuration. I was surprised that we were able to run as high as 1.7 bar on Japanese pump gas with no detonation & able to tune it well enough to keep the exhaust temps down & still run a buttload of timing. I HIGHLY recommend FC Dataloggit when using a Power FC for tuning, especially when using a wideband & full instrumentation like we were. After pushing the limit with tuning, I re-adjusted my max boost back down to 1.5 to try to keep the motor together. I found myself very glad that I invested in ARP head studs & a Tomei 1.2mm headgasket when we dropped this motor in. The HKS 264 10.5/10.0mm cams are choking off this combo, along with running "conservative" boost on these stock pistons.

I can't wait to eventually throw all of this back together with my fully built motor (sitting in the shop & waiting) with solid lifter Tomei cams, fully worked & ported head, and all forged internals! I will be using water/methanol injection in the US to be able to boost high on the crap they call high octane there (only 91 available in Albuquerque New Mexico! :mad: ). I also have pretty much maxxed out a single Walbro 255L pump & will have to upgrade to twins with a larger Sard fuel pressure regulator...

Well...I bit the bullet & went to Odotec (Local APEXI dealer here in Okinawa) to dyno it...results were pleasing though...522 rwhp

This is with 93 octane pump gas & 1.7 max boost (~24 psi). Not too shabby considering that this is a pretty much stock internal motor with weak-sauce HKS Step 1 264 hydraulic lifter cams & only a 1.2mm HG & ARP studs to keep it from "grenading". I can't wait to put my fully built motor in (the next car) with this setup. With methanol/water injection & fully forged internals, fully ported head & solid lift Tomei 270 12.5mm lift cams, 600 rwhp should be attainable. The turbo definately will do it! It screams!
