    Loss of power above 4k

    Hello everyone. My car runs fine at every aspect except when going WoT above 4k rpm. Seems like the car is screaming but the rpm isn't rising fast and there is substantial power loss. Here is some info. 1- IMRC is removed and car has a canned tune so it's not an IMRC issue. 2-...

    I just rebuilt the engine and it seems an injector is not firing. I have tried two different injectors and it is the same issue. How can I test the wiring?

    Gt abs in a cobra

    Will a 96 GT abs module work on a cobra? I wouldn't mind a bit of reduced braking performance as long as the unit works.

    Re-usable bolts?

    I'm going to start my rebuild soon. Block is an iron block ( from a normal mustang GT ), rotating assembly is MMR 900 ( with ARP hardware ) and I will soon be installing new valves in the heads as well. Now I know that head bolts are torque to yield, are the camshaft to sprocket bolts also...

    Is MMR still active?

    I've been trying to get a hold of them through email and no answer. Today it said " mail failure notice " I just received a few parts from them and was quite impressed. I'm planning on buying a valve set.

    96 mustang cobra Hans module.

    Did early 96 mustang cobra's come with the older type ABS module? My ABS module looks nothing like the 96-98 modules they sell on ebay. It looks like the ones on sn95 5.0 mustangs.

    Engine compression with a Turbo.

    Hello everyone. I'm in the process of rebuilding my engine. The car will see turbo boost. What's a good compression ratio that I can use so that if I decide to remove the Turbo in the future the car will not be slow naturally aspirated. I'm assuming 9 is the stock compression ratio...

    Gt TL headers for Turbos

    I have a pair of long tube headers left over from my old 97 GT. Would using these be more beneficial than the stock cobra cast iron headers for a turbo charged application?

    They took apart my engine today for a rebuild. Just before the shipped it to the machine shop I took a couple of pictures and noticed something wierd. No knock sensor bungs or sensors in the engine bay. I'm starting to wonder if this engine was rebuilt before Here are some pictures, what...

    I'm looking for a piston/rod/ring combo that will withstand 700 rwhp. Any advice on where to go? I've already contacted MMR but I'd like to know my other choices.

    Forward facing headers.

    Hello everyone. My engine is getting a rebuild. And I was thinking of flipping the headers forward to feed the turbo. The car is a 96 cobra with a Pa-racing tubular k-member and an oil filter relocation kit. Can the stock logs ( cast iron manifolds ) be routed? Will I have to remove...

    Misfiring persists. Need help.

    I thought after hearing a " woosh " sound that I blew a spark plug. The car gave a code p0340 ( camshaft sensor ). Today I removed all sparkplug wires one by one and I didn't feel any pressure. Would a camshaft sensor cause misfiring? Car is misfiring and sounds like a diesel truck, it can...

    Coil over spring rate.

    I'm about to order a UPR coil over kit with 12-275 springs. Car is a street cruiser. Would these suffice? I'm trying to make some room for my Turbo piping.

    Sparkplug thread repair kit.

    What would you advise on a 96 cobra? 200$ seems a lot for me to drop right now for a Time-Sert repair kit. Are the Dorman's any good?

    Car running horribly p340

    Threw a code p340. Happened when it was cruising and I herd something like high pressure let out. Car was spluttering mildly on idle. Disconnected maf and car is running the same. Can a bad camshaft sensor do this? Or my other guess is that the spark plug backed out. It happened at WOT.

    Safe boost with a turbo.

    I know that the engine is a ticking time bomb when adding boost. I will use a mild-tune, 60 lb injectors,BA-3000, methanol injection, cooling mod and a new 255 lph fuel pump. The turbo is a 62mm small turbo with a built in wastegate but I'm adding another one ( 38 mm ) just in case. For...

    Car has white smoke coming out of the breather.it's not much more like a haze and doesn't increase much when I increase the throttle. Car is working fine and pulls hard. Should I be worried?

    Switched to a breather system and....

    Engine seems more " relaxed " now. The whole engine seems to be making less sound and feels a bit smoother. It might have been a vacuum leak from my old oil-seperator system but nevertheless it feels better. Even the wife commented on how the car is less noisy.
