I bought the car in November 2007 and ran with a crappy tune for quite awhile and a mp t70. Car ran 11.40 @118 on 10psi. Then I burned up two pistons. So I began my build. Here's my 03 cobra project.
Engine... .020 over teksid block, diamond 11.5cc pistons, svt manley rods, arp2000 rod bolts, arp2000 head studs, arp2000 mainstuds, speedpro bearings, moly rings gapped at 22/20, factory cobra crank, balanced. Lightly ported/cleaned up/milled 03 cobra heads, good valve job on stock valves, comp valve springs, 98 cobra intake cams, 03 exhaust cams, degreed very close to 111/111, ported mach 1 intake. Final compression ended up at 9.27:1.
Fuel...returnless for now...twin gt pumps, stage 2 fpdm, pprv delete, stock rails and lines, 60lb injectors, and buying an ais methanol injetion kit, stock maf with MAFia.
Turbo.... Custom built hot and cold side piping, ebay 24x12x3 front mount intercooler, 44mm ebay wastegate, ebay bov, masterpower t76 qtrim, 1.00 a/r, open 4" ss downpipe. BTW this turbo kit has stock ground clearance and works with stock suspension!
Suspension: Front- pa racing tubular k-member with spring perches. All other is stock up front.
MM full length Subframe connectors
Rear-UPR upper and lower control arms, spherical bushings, strange 10 way adjustable shocks, gt springs with 1.5 coils removed
Driveline: Built c5 automatic with hurst shifter and tci manual valve body (switching to transbrake early next year), foxbody driveshaft with lakewood loop, 31 spline 8.8 out of my 97 cobra with frpp diff cover, axles, and t-lok unit. Currently has 4.56 gears, but switching to 3.55s as soon as its done.
Wheels 15x4 &15x8 prostars 275 60 15 et street radials.
The car will be tuned on 13.4psi (my wastegate spring) and 16psi on 93 octane and spraying straight methanol. Let me know what you guys think! I’m eager to see what it makes and how it runs!
Here are some pics...I'll get more up as the project progresses!
