I'm going to throw a 4" muffler on my currently open 4" down pipe off of my pt88 4v set up. So far I've been looking at magnaflow and dynomax race mufflers. Anyone running a set up like this on a big single 4v? Lots of LS cars like this but I'd like to hear a turbo cobra with a large single...

I have recently decided to swap to a th400 from my current c4 set up. The car is a 3400-3500lb 2003 cobra, 283ci (+20 bore), 9.2:1cr, 98 cobra intake cams, ported mach1 intake, cg fab headers, custom 2.5" cross over, 4" open down pipe, 3 to 3.5" cold pipe with 31x12x4 a/a cooler, pt88 turbo, vmp...

My turbo 03 cobra is in the process of receiving a new turbo, piping, fuel system and more. The radiator leaks bad. I can't clear much thicker than stock 1 3/8" before having turbo clearance issues. I bought a stock replacement at Oreilly's, but it's only 1" thick. Will being 3/8" thinner be a...

Selling my master power t76 q trim and going a different route. It has 6-8 in boost pulls (14psi) and no more than 100 miles. The thing is practically brand new. I also have the 3" 4 bolt down pipe flange with allen headed bolts and a 3 to 4" down pipe. Turbo with down pipe flange with 3-4"...

Upgrading from 60's to either 80's or 90's. Bosch makes the high impedance 90's. If I buy new 80's I'll go through Tousley ford, but what brands are ok to look for used and which set would you run. The rest of the fuel system consists of rails, -8 feed, twin gt pumps, stage 2 fpdm. Its for a...

Wanting to sell my 38,000 mile 90mm MAF (OEM) $115 OBO works like new. And my MAFia with about 200 miles on it $115 OBO. I'm converting to blow through with an HPX meter and have no other need for it. I'm not on here often so the best way to reach me is email. [email protected]. Thanks

I have twin gt pumps, stock hat, stock feed line, stock rails, lethal stage 2 fpdm, pprv delete, and 60lb injectors. How much would a larger feedline to the stock rails help? How much would this cost? Just need the line and fittings to make it work.

Well my inlet pipe was close to hitting before and I tried to add a spacer (mmr's) and it looks like the inlet pipe won't clear the hood. So my options are spend money and have a new pipe built or recover a little money and sell the spacer. Will removing the spacer actually hinder performance much?

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...

At what power level will a 2 1/4"- 2 3/8" internal diameter cold side piping be a restriction? I've seen cars with 3" go over 2000rwhp just curious how far mine can go. Also at what point does the exhaust piping become restrictive (the piping before the turbo). After the turbo is a 4" open...

My 03 cobra build... My friend set it up using his user name since I'm not a member over there. The motor is going in Friday 12/4/09!!! Let me know what you guys think and what kinda of numbers it will make and more importantly times it will run in the 1/4!.

Trying to finish my motor. It's an 03 cobra... Switched to a teksid block and one bolt was hole didn't match up. So what do I do? I need this done as soon as possible. Let me know thanks.

How much rwhp will my set up support through an auto? Twin gt pump, stage 2 fpdm, pprv delete, 60lb injectors. I'm hoping to make 600-650rwhp with the mehtanol on 93 octane. I'll be selling my returnless stuff next year and going to a return style system with 80lb injectors. Basically I just...

I have an 03 cobra and am thinking about switching to a return style fuel system. How much could I get for my 03 tank, gt super car pumps (2), lethal modified stage 2 fpdm, pprv delete, stock rails and feed line, and a set of 60lb injectors. The pumps,pprv delete, and fpdm only have about 3,000...

I'm going to be only running pump gas for quite sometime at 10, 14 and 16psi. the motor is 9.5:1 with ported heads, 98 cobra intake cams and a ported mach intake. The car has a solid axle and c5 automatic. I'm torn between 3.55 and 3.73's. I want the quickest 1/4 set up possible but don't want...

Selling my IRS...has at most 45,000 miles on it and is in good condition. Comes complete from brake to brake and has a red brace on it (unsure of brand). Everything worked fine, just pulled it because I swapped to a sra. $850 obo+ shipping, pick up preferred. Its in Springfield MO.

Link to pics... http://www.mipmotorsports.com/id9.html its the red 97 with the cobra r wheels, spoiler, black beauty headlights, etc. I've been off and on about selling it, but I decided finally I don't need two toys at this point so this one needs to go. And I can e-mail more pics. Heres a...

I sold the brake lines with my IRS (just unhooked them with it at the back of the car). Where can I get new brake lines that will work? Thanks!

I'm wrapping up my turbo 03 cobra rebuild and build up (waiting on heads to get finished and time to assemble). But I was thinking about just selling it to get out from under it since I still owe on it and building my 97 instead. I've been tossing this idea around for awhile, but basically I...

I currently have a 24x12x3 fmic on my car. At what point (on my pump gas set up) do I need to switch to something larger? The one I want is another cheapy on ebay, but I've seen it work really well on high hp applications and is 31x12x4 but I don't know if that big is necessary yet or what it...

My set up is: 2003 cobra: 284ci> teksid block, .020 over, .004-.0041 ptw clearance, diamond 11.5cc pistons (9.1:1 compression), plasma moly rings gapped at 24 and 20, stock manley svt rods with arp2000 rod bolts, arp main and head studs, stock 03 heads with mild port work, comp springs, 5...

I'm still working on getting my car back together, but its a turbo 03 and it see's some street time, but is not my daily driver. I do not have a thermostat, I just run a restrictor (different depending on time of year), and when my motor let go last year my oem waterpump was leaking so I'm going...

Well, as soon as my turbo shows up in a few weeks I'll have all my parts to get my car back together and after a short break in on the old tune (with a wide band hooked up) I'm having it retuned for the new set up...anyway, let me know what kind of power I should make and more importantly 1/4...

I am feeling like a broken record, but I am getting closer. Its about time to actually get a new turbo on the way... I really wanted my 97 cobra to sell first, but I may go ahead and buy one in a few weeks...had a masterpower t70 .96 on the stock motor,but want something bigger as that had no...
