rlogan Posted February 6, 2012 Report Share Posted February 6, 2012 Well, my spec miata (that never was) just doubled it's number of cylinders. I traded off my my ART 1.8 and a wee bit of cash for an LS1 T56 CTS-V drivetrain. I was offered a deal I just could not pass up. In one fell swoop I now have every part I need to build a V8 miata except for a fuel pump and some much larger brakes (and cojones) and wheels/tires. If all goes well, this build should not take too long... The motor and trans are already sitting on the miata subframe with suspension intact and same with the differential. I have a full wiring harness including gauges and ECU. Full Exhaust, driveshaft, radiator, oil cooler and lines The motor is a bit excessive right now (450hp+)...and that was actually the only issue that made me hesitant to make the leap at first. I'll have to see what I can do to get power down or maybe just sell it off and build an L33. Buy the rest of my SM parts in the FS section so I can pay this build off. Let the build commence...

RavynX Posted February 6, 2012 Report Share Posted February 6, 2012 Oh wow, for the Spec Miata eh? Are you still building the turbo setup on the 99? Let me know when you're working on it as I'd like to watch/help out since I'll be doing the same in a year or two. Link to post
rlogan Posted February 7, 2012 Author Report Share Posted February 7, 2012 Yes, keeping the 99 turbo for TTA/Street use and the 94 with LS1 will be wheel to wheel car, likely Super Touring 2. The amount of overtime I get in the next few months will determine how fast the LS build goes. Well, I'll be able to get it up and running, but I'll need some flares, larger tires, track suspension, etc...to make it track worthy. The 99 is done for the most part...except I need to install the MS2PNP and sell the HKS Fcon ECU I also plan to mount that airfoil I picked up and add a splitter...hopefully before Cresson in March. I'm plannning to share the airfoil between the two cars. Only one will be at the track at any given time....so why buy two. I may do the same with the 11.75" brakes/11" Corrado setup, at least for the time being. Both use same calipers so it's just a matter of swapping rotors and mounts. Link to post

Only one will be at the track at any given time....so why buy two. So that you can realize that you only need one, and then sell me the other one at a reduced price. Link to post
rlogan Posted February 8, 2012 Author Report Share Posted February 8, 2012 Hell, it's just sitting in the garage right now...but I warn you...if you try it out you will want one. Link to post
snakeeyes1 Posted February 10, 2012 Report Share Posted February 10, 2012 What's the curb weight of an LS-powered Miata? John, I don't know if you've had yours on a scale. I'm curious as to how it compares to a stock NB or an SM car. Link to post
Megahellastylin Posted February 11, 2012 Report Share Posted February 11, 2012 There are a lot of variables, but basically the LS1 swap only adds about 100-200 lbs over the stock powertrain. Mine weighs 2450 wet no driver (weighed on Longacre wheel scales). With a T-5 transmission (instead of a T56, what I have) it will be lighter; the T-5 is about 70 lbs lighter. Stripped to the bone it can be in the 2200-2300 lb range IIRC based on other all-out track only LSx builds I have seen. If you consider the added weight from all of the turbo and drivertrain equipment it would take to make the same amount of power (with a Miata block), with the same level of reliability, the weight difference is pretty small.
