NASA ST4 - U build thread - engine swapped

[gt5759]

Had some more time to get work done! Engine bay is finish painted along with the firewall being welded up and gutting the hood. Finished shooting the interior yesterday, ran short on paint so the insides of the doors need finished (used far more paint than I anticipated) I forgot how much I hate painting interiors, places like the bottom of the back deck and just all prep work in general, but she's all pretty now!
Rear diff and refreshed subframes are installed. I have the drivetrain out so I'm making the shifter linkage and shooting all the drivetrain mounts. I think thats about it for now.
Few little side notes as parts are being made and slowly coming in. Wheels are being made by KOYA in AUS, 17x10 +40et, only 17x10 that wouldn't cost me a small fortune to have made that is a quality wheel, could have just gone with a smaller size or some cheap xxr's but didn't feel that was right way to do it. Rear wing is being built by TOP STAGE composites in AUS as well, I just didn't really like the designs here in the US. Very excited for both to arrive, probably at least a month or so out though













Lots of suspension pieces inbound as well, looking forward to just bolting so stuff on for once haha.

paint looks great! what did you pay for the wheels? I have also been looking for a decent 17x10

I am also interested in the wheels. I have also been looking at Augment wheels in Canada.

$1998.00 USD shipped - SF15 - I picked a custom color so a person could do a regular black or grey for $1737.00. Shipping is the most expensive part but considering that this set of wheels is only a little more than what a single custom forged wheel is its pretty cost effective. Now if APEX would have made a 10" or Konig did, I probably wouldn't have gone this route. I also wish they had other designs at Koya in 17x10 but this is the only, beggars can't be choosers for a proper race car fitment.

Thanks man, that is a huge help! Not sure why its such a rare spec with 5x100 especially with the silly stretched tire trend.

also are you doing any flares or "widebody" to help with the tire fitment?

Yeah one would think this would be an easy source in this size but every single 17x10 in 5x100 is low offset like 20 to 0

No flares or widebody, at most rolling fender edges. I run wheel to wheel so contact is inevitable and I don't want high-cost body parts to deal with. With my measurements and a minimum of -3.5F and -3.0R these fit perfectly under the stock panels.

This is huge. I spoke with Apex and they didn't seem to have any interest in producing a 17x10.
Thanks for bringing this up!

I love this project. And it's cool you're doing some things differently than many others. I'm looking forward to seeing the wheels.
I'm surprised you went through all of that to get a 17" x 10" wheel though, when you said Apex is appealing, and you could get a 9.5" wide wheel from them. Why were you so set on 10"? When racing W2W I'd think replacement wheel accessibility would be a significant consideration.

Thanks! I appreciate it.
Multitude of reasons on the wheel. Its closest to optimum for the tread width of the tire I am running in my class, steering feedback, tire wear, response. Also when I choose to run a bigger tire when playing with higher power outputs, it makes it easier to do so. As to accessibility it is very significant, I will have three sets of wheels though, 2 drys and one wet.

Finished up the doors last night and did the quarter window panels and trim. Just using SEM trim black to make them kind of look like moldings and more or less disappear. Another piece of the puzzle done!

Getting some things assembled, painted and fitting/building new parts. Shifter and linkage is built and drying currently, used the base plate from the factory boot and the rubber portion for a gasket, turned out really good. The shifter is from amazon for a bmw e36, best $35 bucks I've spent in a while Made brackets for the factory door handles so they just go away. Seat belt mounts are all done on the driver's side, need to finish the passenger side but its no priority as it will require another $800 seat which I don't feel like buying at the moment, ride alongs can wait a bit Drivetrain is back in so I can start building on that along with the accusump, fire bottle and surge tank to plumb those in as well. I will get the dash made this week also if all goes as planned.

It's starting to feel like a racecar!

FWIW: I set my Accusump up with a push/pull cable. I had problems with 3 different electric valves. The one from Accumsump stopped working and 2 from Moroso leaked.

Hit it on the head! I don't use electric ones due to issues as well. I'm either going to use a cable or just mount the ball valve on the trans tunnel, earls have a good-looking valve that I think would look nice in the cockpit. https://www.holley.com/products/plum...arts/230510ERL it's really expensive for a ball valve since you can just use a brass one from Home Depot for like $10 and run a throttle cable to it.
