Is that a K24?

Efini~FC3S 03-29-2016 03:24 PM

K20A2

I'm converting the car to run SCCA STL class. No more Chumpcar for the car. May run some WRL races but will mostly be focusing on SCCA stuff.

Need spoon feeding...
 
So I need some suggestions from the all knowing horde here on MT.

I'm about to completely re-wire this POS (at least the chassis harness), and I need recommendations on wiring tools and supplies.

I'll be using a conversion harness from hybrid-racing as well as OEM Acura wiring harness for the engine and charging. What's left for me to wire is the chassis, but because racecar, there's not a whole lot to do. Basically brake lights, wipers, and gauges.

I have always loathed doing electrical/wiring. Like, absolutely loathed. I think part of the reason is I've always used the shittiest of tools and supplies (not to mention a basically non-functioning soldering iron). Using crappy tools and supplies has led to even te simplest wiring tasks turning into mind numbing disasters.

I need a good proper crimping tool, some baller easy to use connectors, and maybe a generic fuse box.

So what do you guys use? Amazon Prime is preferred. I don't mind spending some money, but I also don't need top of the line stuff since I don't (nor will I start) do this stuff every day.

Thanks in advance

More important then wiring, when do I get to go back to VIR with you and smoke some meat.

Well it definitely won't be until after this car is wired up and running...

But more to your question, either Aug 12-14 (VIR 24hr Classic) or potentially Dec 16-18 (eep cold!)

A case of the car becoming too nice/expensive/hard to replace, or Chump becoming not cheap enough to justify?

The car was always too nice for ChumpCar, at least at first.

Probably more of the latter. For the amount of money I was spending to do a ChumpCar race I could do like two SCCA Majors weekends, get more total seat time, much less stress (not worrying about appeasing paying renters), and actually win money and contingency.

Don't get me wrong, I really enjoy ChumpCar, but maybe more so as a guest driver.

First picture is from February 29th. Second picture is from a couple days ago, but let's say April 29th.

Hoping to make the Majors race at Pitt in a couple weeks. Most of the work left to do is wiring. Hoping to have that done in 7-8 days, that will leave a couple days to get the at dyno'd and tuned with the sweet 50mm restrictor required by the rules. Need to be at ~200whp to be competitive.

After that will be the Mid-Ohio majors in early June. There are currently 32 STL cars registered for that event. Planning to have an LSD and 5.08 FD installed in the spare transmission by then.

Looks great luke, but the timing belt is on the wrong side...

VTEC unicorns make more pony powers when the TB is on the passenger side...it's the only way to go!

The transmission is on the wrong side too though...

Random picture dump of some of the last two months activities. This would be in chronological order of the mobile site would let me...

aidandj 04-29-2016 04:46 PM

Got any pics of the spoiler?

Efini~FC3S 04-29-2016 04:54 PM

Not really, it's ghetto, you can do better.

I built it with ChumpCar rules in mind so I had to use as little materials (aluminum and Lexan) as possible.

if I get a chance I'll snap a few more pics for you. I have to change it (or remove it) because it doesn't currently meet all STL rear wing rules...

Efini~FC3S 07-22-2016 05:42 PM

So K-swap has been done for ~ 2 months.



Did some racing:

https://cimg2.ibsrv.net/gimg/www.mia...e673e82281.jpg



First race/shakedown went okay. Had some driveshaft boot issues, and no LSD was a problem.


So I installed an LSD:

https://cimg7.ibsrv.net/gimg/www.mia...90dc470480.jpg


OEM 8th Gen Civic Si LSD into a TSX 6-speed transmission. Then I raced again. And I was too busy fixing driveshaft problems to take pictures. Or take video. Currently working with Driveshaft Shop to try to fix driveshaft issues. Basically inner boots tearing, and driver side axle popping out of the diff housing ~30 minutes into a race. Which is annoying.


Only pics I took from SCCA Majors weekend at Mid-Ohio. I was running ~6-7th out of 35+ cars with a totally undeveloped car (no aero, laughable suspension, down 10+ hp / 15trq to top cars, no fancy LSD, etc.) before the axle would pop out. Had some awesome racing though. I really wish I would have set the gopro for Sunday's race, had some intense back and forth with a 2nd gen RX7 and 1.6L miata (both STL cars) fighting over 6th place. Proper good racing. Super clean, super fun, and at a high level. That's what I've been missing.


https://cimg0.ibsrv.net/gimg/www.mia...fac54eef15.jpg



Car isn't really a Chumpcar anymore, probably should change thread title.

Planning on doing some track days to fix/test the axle issues, then hopefully do one or two WRL/AER enduros. Over the winter I will finish upgrading the car so that it's hopefully competitive for the Runoffs at Indy in 2017.
