Ls1 Mx5

Hello all, just found this site, decided to introduce myself. I just did so over at MiataTurbo and a lot of them weren't so receptive to my carb (I understand why, efi is ultimately better). Any way I'd like to get more feedback on it, they gave me some helpful ideas/criticism, I'd love to hear more

It uses a v8roadsters standard kit
-Ls1 I rebuilt with an Ms4 cam/t56 6-speed
-Rx7 TurboII rear end/axles with Miata Roadster swap hubs
-Custom torque arm and traction bars
-Seam welded most of the car
-Tein coilovers
-HUGE ebay aluminum radiator
-ac/ps/heat delete
-sanderson shorty headers/custom 2.5" duel exhaust with no crossover/x pipe
-s2000 steering joint
-tooo much to list :blaugh:

I built this car with my dad as a father son project. We did EVERYTHING using HANDTOOLS and FLOORJACKS. We even do the wheel alignments on all our cars

I brought this car back to life with a whole bunch of little modifications that added up to a much better package. To start I purchased a proper welder that runs on a 220 line and not on my crappy garage 110 that was hindering my other welder.

-I re-seamwelded the transmission tunnel inside and outside
-made the fuel tank bottom sump with an 8an fitting welded to the bottom
installed braided line and relocated the fuel pump to the bottom of the car where the original fuel filter went
-I strengthened up the mounting of my jdm s2000 steering joint
-welded 90 degree 2.5" pipes to my headers and put flanges at the bottom
-strengthened my rear k-member
-installed a much larger aluminum radiator, and did a whole bunch of other things I can't think of right now.

Next on the list of things to do is to re calibrate the eddy carb with new jets and metering rods. I'm shooting to lean it out a lot. Tell me what you guys think

My favorite new additions by far are my 15x9 Nickel 6UL's wrapped in 225/45/15 Hankook RS-3's. Check it out












I have matching 3/16" steel plates with four holes each on the top side of the floor pan that the plates welded to the DOM tubing get bolted to. Also, while it was out of the car I seam welded it all up. The DOM tubing btw is 1.25" with .25" walls. Real over kill

This build is nice. I am curious to how thr t2 rear end is holdong up. I may go that direction with my ls1.

Also is the ebay radiator for a miata?

Don't care what the turbo guys say that is one sweet car!! Great write up too!! Nothing wrong with a carb, it's easy to put together and will never leave you on the side of the road with a bad sensor. Welcome!!

Welcome from Sarasota Fl. Nice ride!

Thanks for the kind words, T2 rear end seems to be bullet proof I'm running it with the discontinued miataroadster hubs, and yes the eBay radiator is for a miata, its a nice unit. That v6 project you had going was cool but you're going to love the Ls1!

Thanks a lot, I feel the same way, simple, easy and no miles of convoluted wiring harnesses to be dealt with


Thanks Jim

Really be curious what you'd see on a dyno. I do enjoy carbs, pretty, easy to tune and simple.
