I was going cheap, so I didn't want to buy the IMRC delete plates and intake gasket. EGR stayed because I wasn't going to tune it for a while and I am in an emissions county.

IMRC delete is free if you do it yourself

Gaskets are not. I was on a shoestring budget.

The gaskets are reusable.

i have emissions also so i guess the EGR will be staying. is there a big advantage to doing the IMRC delete?

Yeah, you are in the same area of Texas that I am. TBH, you could probably get a plate and block off the EGR and they would never know it. IMRC delete gives you a bit more mdrange and high RPM power.

Default 4v swap

i had a couple of questions about the swap. After reading this article I got excited and bought a mark 8 engine for about 300 bucks. (great deal) I also got some long tube headers, etc. so here are my concerns now (should have done more research)

1) will the long tubes work with the swap?

2) instead of doing the IMRC delete I just opened them up from the back of the engine and locked them open with the metal shim that is located there. since it is out of the car it was quite easy to do. would this be ok?

3) i heard that the heat on cylindar 7 and 8 tend to get hot and blow plugs etc. since the engine is out of the car should I get a cooling MOD?

4) would a 99 aftermarket inlet tube work?

5) do you have pics of the heater hose fix issue?

6) would i have to swap the 96 gt fuel injector lines with the mark 8 engine?

thanks for any help you can give me. just like you, im on a shoe string budget. i hope to god this engine has no problems since i got it so cheap

1) If the headers are for a 2v SOHC no they will not work because the 2v exhaust ports are circular and the 4v are rectangular.
2) You can tie them open but why not just delete them if the motor is out instead of having possible issues down the road.
3) The cooling MOD is a concern with C heads, specifically on 03-04 cobras. This motor has B heads.

4) would a 99 aftermarket inlet tube work? It depends. do you have a 97-98 MK VIII engine or a 93-96. if tis 97-98 then the 99-04 inlet tube SHOULD work.

5) do you have pics of the heater hose fix issue? what issue? if you mean the cooling mod, like stated above, its not necessary for your situation

6) would i have to swap the 96 gt fuel injector lines with the mark 8 engine? what year is your mustang? this will allow us to help you

ok the mustang is a 96 gt. the engine (mark 8) i got is a 1998 however it says november 97 on the engine itself so i think it was built in 97 to put in the 98 model not sure thought. the heater hose issue is what the author of this post stated he had to do in order to make it work. that is why i was asking. hope this helps and thanks for the info you are giving me.

sorry to keep this up however i have another question about the swap. 1) is the alternator setup the same or would i have to convert it to work with the gt wiring harness, i know that they are diffrent however are teh electric components the same?

2)would the mark 8 motor mounts fit or should i swap the ones on my 96 gt.

3) i dont feel comfortable attempting to thread a hole in my coolant crossover tube. also 93-95 mark 8 coolant crossover tubes are hard as hell to find. i was wondering if i were to splice the 2 sensor wires together and make it one would this work?

thanks again

Great thread.

ok so I have read every post in this thread, I have a 99 GT with 200k+ getting a free 94 mark viii tomorrow, the way I read it the 94 will be a non cop motor, but some people act like you can use the valve covers from a COP Mark Viii on the non COP 94 engine and use COPs? am I right here? or does it take diffrent heads for the COPS? also if I have the whole car what all should I get while I'm pulling things out? will this motor swap into my 99 GT at all, how can I delete the EGR, and what is the best route to delete the IMRCs?

You can use cop valve covers. I would suggest a 96-98 cobra intake manifold if your running those b heads. It is also a good time to install headers when you have the engine out.

I have a question. Hopefully someone can answer. I have an 04 sixxer and am in the beginning stages of this swap. I have an ecu and gauges from an 03 GT, but don't have a harness yet. Will the dash harness from an 01 Cobra work with my GT parts? or do I NEED to get the harness from a GT?

Thanks
