Been Lurking for a while Ls1 Conversion
32 Attachment(s)
Hi all, I never officially introduced myself here but you guys seem like my kind of Miata guys. Anyway here's my car tell me what you think
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. The only thing we didn't do is rebuild the trans, I sent that out to Tick transmissions. 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 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 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 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 https://www.miataturbo.net/attachmen...ine=1349645715 |

Fail. edit: link to your sr20 build thread if you have one? If you do I must have skimmed over it when I checked your threads 2nd edit: heres an old vid of it |

But to each their own right? Thanks for the input edit: link to your sr20 build thread if you have one? If you do I must have skimmed over it when I checked your threads 2nd edit: heres an old vid of it Good job pulling off a v8 conversion. That already is a big accomplishment. However obvious stupidity like thinking carburation is superior to efi will get you eaten alive on this forum. Seriously, they're ruthless when it comes to intentional ignorance. So just be careful and try not to throw out statements like that unless you actually want people laughing at you. Car sounds good and looks like its a lot of fun despite the carbufailsion;) |
I forgot to mention... awesome build otherwise. With a bit more education/experience you would realize that EFI really isnt the black magic it is made out to be. In fact GM's ECU's are pretty awesome for open ecu style tuning. So yeah, making any "Carbs are better" statement on this forum is bad lol.
Always good to see father son projects tho. enjoy the car Oh and no I don't have an sr20 in my miata. I had 240's before getting into the miata world. Everyone makes mistakes...mine was being a ricer. lol. |
I remember the last guy on here who had carbs.
It didnt end well. Seriously, Megasquirt that thing. Carbs are shit. |

David, glad to see you make it over here. If you guys ever have a chance to view his build thread on m.net you will see a determined young man that knocked out this car in something like 4 months. He started way after I did and was driving it WAY before I was.

Welcome, ls1mx5. Check out the Miata Gallery and post up some pics!

Nice build, too bad its carb'ed. Have fun getting it kind of running ok in one or two conditions while getting dirty and covered with fuel and getting your eyebrows cooked off from a backfire tuning it in. I'd only point an laugh a little bit while comfortably sitting in the car with the laptop making it run perfect in all conditions with hp tuners on the stock ecu and wiring harness.
Using easier as an excuse for a carb ls1 is just silly. The ls1 engine harness is already setup as a standalone harness from chevy. Zero wiring additional to the carb install is normally required unless you want it to look pretty, just route the wires, plug things in, starts on the first crank (after disabling the anti-theft with hptuners). Then getting that magazines 100 hp gain is as simple as throwing on a different manifold, tb, and intake (maybe injectors, forget the stock limit on those). But you've already done it and had to cut the hood to make it fit, so be it. |
FAST? Haven't you ever heard of LS1Edit? Painless makes swap harnesses, or you could easily just hack up a stock LSx car harness and use the factory PCM......
Carbs fucking suck, but None the less, Cool swap anyway.

I appreciate the compliment/advice. As I keep saying, efi is in the cards for this cars future...

Nice build...RANT...hp tuners...etc
This project has been on hold because of school and my cbr600 f2 streetfighter project. I plan on cleaning it up a lot and installing a classic round headlight: https://www.miataturbo.net/attachmen...ine=1349734762 https://www.miataturbo.net/attachmen...ine=1349734762 https://www.miataturbo.net/attachmen...ine=1349734762 https://www.miataturbo.net/attachmen...ine=1349734762 |
Lovely execution. The car looks fantastic, did you paint it too?
BTW, does your rubber fuel feed line run over the motor? |

BTW, does your rubber fuel feed line run over the motor? The rubber fuel line goes over the passenger side valve cover to the carb feed but sits pretty high above it, as in about a foot~ or so. Why are you asking? (no sarcasm, I post my cars on the internet mainly to get advice/feedback and to learn) |

Thanks a lot John I appreciate you saying that. What's your username over on m . net?

Thanks a lot, I didn't paint it but at one point it was repainted. I have ocd so I stripped the car to a bare shell and did a bunch of strange obsessive things before I even started the v8 swap to make sure there wasn't any bondo anywhere, no frame/accident damage or rust.

(no sarcasm, I post my cars on the internet mainly to get advice/feedback and to learn) I wouldn't say the feed line placement is the worst, but it will indeed heat up and at some point in time start to leak. I would run some longer hose against the firewall and/or at a minimum, firesleeve it properly. |
I saw your thread a couple years back on m.net...
I know you fucked up the build somewhere and on your first test drive, your engine went dry and you blew it. or something along those lines. Still... not bad for a 17 year or something along those lines. |
