GM LSx engines have been swapped into just about every car under the sun, but this is the first time I've seen this.
It's an LS6-powered Toyota MR-S/MR2 Spyder that's being built by Speedhunters reader Erven as a track toy for a customer. A couple more photos can of the build can be found here.
Please keep us updated Erven, can't wait to see this thing when it's done!
