Thank you. I wanted to try out a meaty setup for a bit and the offset on these rears makes it hard to run these lower without more negative camber. I did the stance thing tucking 18s for a while so its nice to change it up lol.

Thanks man!

Still have an oil drip coming from the thermostat bolt on the FC oil cooler after putting a new Mazda crush washer on there. I am suspecting that the cooler may be cracked but i have not pulled it off to inspect. Anyone have a clean one laying around? Or any suggestions on an upgrade core size/ location? i am going to pull it off this time and add some RTV to the threads and look for cracks. Thermostat is removed and port inside blocked with a bolt/washer/nut. 

Other than that, got a revision on the tune from the datalogs i pulled last weekend. Also cleaned up the cold start and hot idle more and its sounding smooth. Going to change the diff fluid with the KAAZ fluid and put some more miles on it. Still need to change the front wheel bearings and get an alignment. I also spoke with Chase bays and i am going to get them some measurements for power steering lines and the fitting sizes for the rack so that they can get an FC 2JZ kit together. Can anyone confirm that the fitting sizes below are correct, like as in they personally used these fittings on their car without issue? i pulled this from an older thread that freeskier shared.

Any help is appreciated!!



Full interior cleaned up and reinstalled. On the hunt for an OEM maroon drivers floor mat if anyone has one.


Here is the shifter location with the trim on. I REALLY REALLY regret cutting the dash like i did, and totally did it out of impulse during test fitting the shifter assembly. If i could do it again i would cut the rear open. Anyway, driver side fits nice but passenger side needs some trimming due to the opened up shifter hole.


And cut up this unused seatbelt mount cover to mount my old ipod. Cable will be tucked behind the dash and this also hides the A/C controls that i will not be using. Probably overlay this in carbon sometime soon.

Thank you, ended up ditching the little ipod mount because it felt out of place.

Have about 200 miles on the car and wanted to share some initial impressions. Definitely will be doing a full exhaust, this setup was temporary but i feel like the car will be much more enjoyable with an exhaust dumping out the back. Heat management will also be a priority as it gets hot in the car (like 105* in 80* ambient) when measuring at the driver footwell carpet after a long highway cruise. I will probably do some lizard skin or something, have not researched any options yet but open to recommendations. I have not tested the car after adding the hood vent but i hope that will help allow the heat to escape and drop cabin temps. As i knew, explorer 8.8 setup will be a top priority. The current 4.11 gearing with the CD009 ratios puts me at 3000RPM when doing about 65. Will be much nicer to cruise at 1500-2K RPM. Have not calculated which gear ratio i will go with but i will try to keep the final drive close to a supra ratio. I knew most of these areas would need attention but i wanted to get the car running and any bugs worked out before focusing on creature comforts.

Regarding the actual car, i did resolve the oil cooler leak after a third attempt at sealing it and coated the threads with RTV and it is leak free. When the car is hot, i have a small drip from the turbo return fitting on the turbo and have a -10 fitting on order to resolve that (current 2 piece fitting is a flange and then an NPT to AN port that threads into the flange). Recently i started running into a fuel pressure issue only when the car has been driven for about 30 minutes/ hot and the fuel level was below 1/2 tank. If i crank up the FPR it will come up to 43PSI again but will then start to drop down to the low 30S after driving for some time. I suspect this is either from the hot return fuel entering the tank right near the pump inlet, the depth that the pump is currently set at being too high, or from a voltage drop between the AEM pumps 14GA wiring and the splice into the OEM 18GA wiring inside the tank. I verified that i am getting 13.5V at the connector ontop of the pump hanger, but did not open the tank yet nor have i thrown an amp clamp on it. Instead of fucking around with the modified stock hanger i ordered a built2apex dual pump hanger and 2 walbro E85 450 pumps. Also got a radium fuel filter setup and their fuel pulse dampener. Hoping that this will suffice for my current goals to max out the ID1000s on E85 in the future. Still have to do front wheel bearings and get the car aligned but so far so good. I was able to get one solid 3rd gear pull at 75% throttle to 5500PRM and it pulled pretty hard on the rough tune currently flashed. After that pull i did a few tiny 50% throttle pulls while taking this iphone video https://youtu.be/_XAWOe1rMIc

Started getting some nice colors on the manifold


hood cut for the vent


Mounted in final position using rivnuts


Vent openings trimmed roughly and rear cut straight


Templates cut for a better fit. Will be grafting fiberglass pieces in then final prep/ sanding on whole vent before paint.


Chase bays coolant overflow installed




Need to get started on some carbon ducting for the radiator next. Also working with chase bays on a FC-2JZ power steering kit and having some trouble finding the correct fittings so still researching that and exploring options.

Ducting should make a big difference for engine temps.   I know mine did.

I'm trying to remember, do you have any heat shield in the bay/tunnel in those areas?   That should help even more than Lizard Skin.    That said, either Lizard Skin or a good quality butyl rubber + closed cell foam (I like Raamat and Ensolite) should help a lot.   Doing heat shield + butyl + closed cell foam should help a whole lot.

No heat shields in the tunnel and nothing in the bay either other than some random gold foil tape in places near the engine. Appreciate the input though, i will look into my options at some point.

Yes it should with the wastegates orientated differently, There is a lot of room on that side of the tunnel in both the opening, and under the car. Also can snake it above my trans mount which will be perfect for ground clearance

So still waiting on the built2apex double pump hanger. Placed the order on 5/1/18 and was promised 2-3 weeks before shipping. 60 days later and i have been promised 4 separate times that "it is shipping out this week" so who knows when it will actually get here. I have driven the car to a few car meets and cruising it when its not too hot out but other than that i have not done much to it and i am waiting to do all the fuel system upgrades since it is actually a turn key car at the moment. Once this fuel pressure issue is resolved we can continue tuning it and start turning up the boost.

I had some 3 year old epoxy to use up, so i made up a quick 2ply sheet to duct the radiator in. This did help with coolant temps and they drop fast once the fan kicks on now. The radiator fans will also hold a piece of paper to the intercooler when running.





I have been trying to avoid sanding fiberglass in 100* weather but finally got around to patching in the missing panels on the vent. Need to reinforce the backside with fiberglass and then do final sanding and prep before painting it.


Camera is acting up, sorry for the dark pictures.






My 2 piece turbo drain flange kept leaking so i swapped that out with a billet boostlab 1 piece. 


here is round 2 of fuel upgrades. Radium fuel pulse damper and 10micron filter. I have a feeling my cheap brass element Earls filter is related to my fuel pressure issues.


once the pump hanger gets here, i will be running twin walbro ethanol 450s


Finally getting my powersteering setup wrapped up then going to get an actual alignment. I am running a chase bays reservoir, excessive manufacturing high pressure line, and will be putting together the low pressure and feed lines. ** does anyone have the o ring size for the high pressure banjo fitting on the rack? i have lost 1**

The FC is looking wonderful man! Glad to see you installed a rad shroud, a must have no doubt.
Hopefully the 10 micron filter solves your FPR issue on hot start.


It is kinda funny but the less desirable interior colors of the 90's are actaully becoming popular. I have a blue dash in my 91 integra ind it is in very good shape like your maroon interior, anyway I got complimented on how clean and "cool" it was from a younger gear head.....never would have expected that in a million years hahahaha.


Your interior rocks man!

Thanks a lot, i love my maroon interior just because everyone usually hates it. Regarding the fuel pressure issue, i have a hunch that its related to the pump height in the tank ( i set it about 1/4" off the floor of the tank), the return line being too close to the pump inlet and pulling aerated fuel, or the cheap Earls brass element filter i run post pump is causing a restriction. I have adjusted the FPR a few times back to 43.5 and it drops down to 35PSI shortly after and gets even worse when hot.

Anytime i give it moderate throttle you can watch it start to fall out even worse. At first i figured i would open the tank up again 1 time and upgrade to the billet 2 pump hanger and new fuel filter all at once to be done with it. This was also when i believed that i would have the pump hanger in 3 weeks as opposed to 90 days due to this ponzi scheme built2apex seems to be running. Still waiting on the hanger LOL. I still rather get this resolved the right way before continuing with tuning to avoid doing it twice.

Thank you! i am itching to build another harness, i really enjoyed that process surprisingly.


In other news, been collecting parts on the banshee build for anyone that cares. went with a 421 serval cylinder (lower port timings compared to a drag racing port) which should offer a a broad powerband for trails and duning. These setups usually run about 83-85WHP. Hopefully i get my crankshaft this week so i can assemble this weekend and measure the squish band clearances/final checks before installing back into the bike.

Well that Banshee sounds like an excellent and very entertaining way to splatter oneself, LOL.
