[QUOTE="98 Saleen Cobra, post: 13697257, member: 52734"] Well as some of you now know my car has been eating motors.. 3 total to be exact two of which were built by some of the top builders. The first John Tymensky of Modular Performance and the 2nd built by Shawn@AED.. All of the motor blew the same way same piston same everything.. You can follow everything prior to this thread here [url]http://www.svtperformance.com/forums/sn95-cobras-24/959878-my-e85-build-thread-other-events.html[/url] Well AED got the car on the dyno and it was pretty much toasted.. Car would run but they couldn't get it to do anything.. Did a compression test and that was that.. All the cylinders on the drivers side where toasted.. As much of you can imagine I freaked out being that I've now blown up 3 motors.. Not knowing WTF happened (none of us did) Drew and Shaun started making phone calls.. We were all scratching our heads. Well it turns out that there have been a few cases of ECU malfuntions on fueling these cars.. Some times it takes a few motors to figure out..

Luckily everything is going to work out for the new build.. I've had some mental set backs with wanting to part the car and just say **** it.. BUT I'm going to do this built motor thing 1 last effing time.. So here is the run down. Sold the Boss 5.0 block in favor of a very nice stock bore 281 Teksid block.. Saving weight is now key for me.. Custom Pistons aimed at E85 Same Billet I-beam Manly rods as before Stock stroke forged Crank Foxlake Stg 3 Ported heads Custom Cams Stand Alone ECU Rear end setup will be: FRPP 3.73's DPI Differential [url]http://www.dpiracingproducts.com/products/8-8-31-spline-platinum-track.html[/url] 9" ends Custom Axles Fully welded tubes Powdercoated Sold the T-trim to my buddy Pete who has a AED built 96 Cobra.. Bought a JT-trim that has made 960 thru a auto on a 10:1 Comp motor on 20psi I don't really care for what power it's going to make, but I'd be willing to bet it'll be a lot. I have some goals in mind for it, but again at this point I need a car that runs lol.. and doesn't eat motors.. lol..

At any rate, I figured I'd start a build thread so then I don't keep changing my mind on shit lol!! On to some pics. Blown motor and pistons and you can see the drivers side of the block is toasted: [ATTACH=full]527539[/ATTACH] [ATTACH=full]527540[/ATTACH] [ATTACH=full]527541[/ATTACH] JT-trim that I bought, you can see it should go in for a freshen up due to throwing a few belts and the seals look kinda rough. [ATTACH=full]527542[/ATTACH] [ATTACH=full]527543[/ATTACH] I'll keep this thread up to date as I can.. As of right now the JT-trim is sent out to Vortech and Drew is sending the heads out at some point and along with the block to the machine shop to get it checked out and pistons ordered.. [/QUOTE]
