Hi all. All was going great with my C head, Termi/GT 500 conversion until it just died after warming up before going for a drive. The fuel pump just quit. There is a BAP without any boost control etc. Measured voltage at the pump and am getting g 3.8v. Disconnected the BAP and am now getting...

My latest query is regarding the IAT sensor. I was told it is the pictured plug at the back of the blower tucked in near the bypass valve. The problem is there are 4 wires, while the IAT for my 98 has only 2.. the red and yellow/red were twisted together suggesting they are the ones to use. Not...

Hi there . All is going well and the motor is back in the car. My next puzzle is to make the intake plumbing. Space is tight , so I have to rout the intake over the valve cove r, keeping as low a profile possible for hood clearance. I am using a 90mm SCT MAF, so, I assume , keeping the volume...

Hi all. Well, all is going well on my project and the questions will start flowing... 1. On the gt 500 fuel rail there is a fuel pressure sensor which my harness has no provision for(98 Cobra harness).. there is also a nipple on the sensor body. What can I do here? Can I just remove and put...

For my Termi/GT500 conversion I will need to upgrade my fuel line from 5/16 to 3/8". Any advice on how to do this would be great. I've ordered the hard line and would like to use an6 fittings and braided line to the engine. That seems fairly straight forward, but it is where I need to connect to...

Hi all. I am using an H122 from an 08 Shelby on a 4.6 termi swap build. The plan is to keep boost at around 10 psi or so . I would assume a pulley change from stock will be necessary. What is the stock pulley size, and what would be a good size to start with? Is there a chart with pulley...

I'm currently in the middle of a custom Termi insall in my Factory Five Cobra replica. I've decided to mount the IC tank in the trunk, running heat exchangers to the front of the car, through an air to water rad, then the blower. Does the tank have to be higher than the intercooler/intake? It...

I had the misfortune of finding a bunch of timing chain bits on my oil drain plug after doing a C head swap. This was a fatal mistake I made during the assembly of the timing components. I installed the outer lower timing gear backwards, causing the timing chains to interfere with each other...

I'm about to assemble a set of C heads after a freshen up and am wondering if the lash adjusters can be re used. They appear to be in fine shape, but I really don't know how to inspect them. If they should be replaced I was thinking of using Melling. Any tips, tricks or problems i should be...

I've been tying to get some adjustable Cloyes or Comp timing gears (primary camshaft) for my DOHC. Hav had no success thus far. Cloyes no longer makes them, and Comp says they are on back order (from where?) Anyone have a set new or used they would like to sell? Thanks Tom

As the title suggests I'm going F/I as opposed to the N/A build originally discussed in my previous thread. So, I purchased a Termi setup with an H122 GT500 take off from another forume site. For Sale 4.6 4V to 5.4 4V H122 kit My goal is not a max effort race car, but a streetable, fun car. My...

So, I've finally gotten over my mistake (B to C Head Drama) and am ready to move forward. Knowing i won't be driving my FFR Cobra this year, the plan is to do the body work and rebuild the engine in time for next March. I would like to do a moderate effort N/A build, keeping a tight (ish)...

So, last time I posted, I was just finishing a B to C head swap, keeping the B upper. All went well with assembly and install back into the FFR Cobra replica. Started up no problem , oil pressure good AFR good, no leaks, no strange noises, etc. On the first sunny day, went for a short test...

Finally almost done the B head to C head conversion. It has been quite the ordeal.. lots of fabrication and such. Any reecommendations on spark plugsand gap. This is for an emission exempt vehicle if that helps. Also wondering what to do now that the knock sensors have been removed. Should I...

I'v installed someme Ford Boss/F150 rods (CR3Z-6200) in my 4.6 dohc. Having a hard time finding the proper torque spec though. Anyone?

So, the B to C head swap is going well except... when i switched the B intake cams into the C heads one of them was very hard to t So urn. When indexing the cam to align the timing marks it would take almost 25 ft/lbs to rotate. I removed that cam, checked the jounals and seats. All looked fine...

Hi all. Looking to buy a set of ARP head studs for my B to C swap. Thanks Tom

Hi all. Finally picked up my C heads and 01 cobra intake yesterday. The plan is to adapt the B upper hat to the C lower intake. No problem there. While the engine is apart I,ll replace any pieces as needed. This engine is for a Factory Five Cobra which at most may go to the occasional autocross...

As the title states, I'm looking to buy a complete Kenne setup for my 98 SVT Cobra powered Factory Five roadster project. Thanks Tom

I'm looking to buy a complete used Kenne 1.5 or 2.1 system for my 98 SVT powered FFR Roadster. There are lots of Vortechs out there, but they are too hard to package in my car. Thanks Tom

Hi all, I'm using a 98 Cobra engine in my Factory Five Racing Mk 4 build. At first start attempt yesterday it wouldn't fire. There was the occasional pop which would occur out of phase. A little history... I freshened up the engine, having the heads cleaned up and reassembled by a reputable...

Hi there. I'm using a 98 Cobra 4.6 dohc for a FFR Cobra replica kit. I switched to a COP ignition and am wondering which spark plugs should be used. The motor is mostly stock save some bolt-ons... IMRC deletes, larger throttle body, intake spacer, full windage tray, and exhaust. Are aftermarket...
