AggieStang Posted May 24, 2013 Report Share Posted May 24, 2013 Hey guys, I'm usually at moddedmustangs.com, but thought I'd get your opinion as Shelby owners. I recently damaged the pistons in my 2007 gt500 and am trying to decide on where to go from here. It's HEAVILY modified and I'm currently using it as a HPDE/autocross car. My options right now are to: 1. Ford racing crate engine 2. MMR long block 3. MMR short block (if heads are ok) 4. Sell the car as is (how much do you think it's worth as a roller?) 5. Part the car out If I sold the car I would get something lighter.(Lotus exige, factory 5 cobra, etc) Mods are as follows: Ported eaton Pulley swap Heat exchanger with dual fans Larger coolant reservoir Control arms Aluminum driveshaft 6 pt cage Pypes exhaust Hurst then mgw shifter Spec clutch Baer slotted rotors Hawk autocross pads Steel brake lines Nitto nt05 (brand new) Cobra seats Eibach sport springs Link to comment Share on other sites More sharing options...

Secondo Posted May 24, 2013 Report Share Posted May 24, 2013 If it was me and I wanted to keep the car I'd fix it and put a set of Eagle or Manley billet I-Beam rods and lightweight pistons. Then the bottom end would then be capable of whatever you dished out for it. More boost! 1200+ HP! Link to comment Share on other sites More sharing options...
ilmor Posted May 24, 2013 Report Share Posted May 24, 2013 How much money are you looking at spending either way? I might think of lots of things! Link to comment Share on other sites More sharing options...
NMAv Posted May 24, 2013 Report Share Posted May 24, 2013 Put it up for sale as is if you don't want to invest more money into it and aren't sure of the return on your investment. Then whoever buys it can do what they want. Seems nicely modified. Link to comment Share on other sites More sharing options...
ViperNC Posted May 24, 2013 Report Share Posted May 24, 2013 Strip it down and make it a dedicated track duty car. Here is the step by step: http://www.teamshelby.com/forums/index.php/topic/79652-so-you-want-to-go-racing/ Link to comment Share on other sites More sharing options...
AggieStang Posted May 25, 2013 Author Report Share Posted May 25, 2013 Patrick: that's one good looking gt500... Secondo: I'm leaning toward getting rid of it, but I have no clue what it would be worth without a functioning bottom end. I've also put so much money into it and know I won't get much of it back. Any estimates? Link to comment Share on other sites More sharing options...
svttim Posted May 25, 2013 Report Share Posted May 25, 2013 Im afraid you would not be happy with what you get. 10-15 possibly. This is a tough call though. I understand your desire for a lighter car for track. But your going to take a beating if sold as is. If I wre to sell it, I believe I would find a used motor. otherwise, Find a 5.8 or an alumimum 5.4 Link to comment Share on other sites More sharing options...
09 Red GT500 Posted May 25, 2013 Report Share Posted May 25, 2013 I noticed you have NT05s. I know that you indicated they were new, but any idea how they work as a track tire? Link to comment Share on other sites More sharing options...

Any estimates? On one hand you will lose much money if you get rid of it, I think everyone will agree on that one because most people who extensively modified a car experienced massive loss of investment...but on the other hand a Shelby will always be a Shelby (a Mustang really) so if you think about having another type of behavior on the track or on the slalom, no matter how much more money you'll invest, it won't radically change what the car basically is. Beside the financial aspect you should ask yourself what your expectations are in the end. Link to comment Share on other sites More sharing options...

super hiss Posted May 27, 2013 Report Share Posted May 27, 2013 he doesnt have anything done to it, he red lined it probly went past 6800 rpms... if he has a shop, or a buddy and time he can change the rods and pistons out himself. thats what i would do and thats the cheapest. i could only wish i had 30,000 to buy a 5.8 crate engine. ford finaly put 2 and 2 together and realised these crazy ass holes want 4 digits worth of hp... lets build it so it last! i agree with secondo Link to comment Share on other sites More sharing options...

AggieStang Posted May 27, 2013 Author Report Share Posted May 27, 2013 The engine went lean. I was only at 5800 rpms. We haven't checked yet, but we think we may have had a fuel pump malfunction. I've gone through a few sets of nt05s and they are a good track tire for the money. Link to comment Share on other sites More sharing options...
frydguy79 Posted June 6, 2013 Report Share Posted June 6, 2013 i would do the BUILT TO THE HILT mmr short block my self... how many miles are on the car??? Link to comment Share on other sites More sharing options...
Imatk Posted June 10, 2013 Report Share Posted June 10, 2013 I've heard good and bad about MMR. I'm not sure how I would go in your position actually. If you know someone who can build it locally I might go that route, at least that way you know the person and you'll hopefully get what you paid for. Good luck man... I wish these cars had knock sensors like the newer ones, that would have probably saved your motor :\ Link to comment Share on other sites More sharing options...
