what would it take to convert my engine to a dohc 4v engine...i was looking at the fr500 engine...and the question poped into my head..i have no inclination in doing it...i just was wondering...

 

4v heads, 4v cams, intake manifold, wiring, fuel rails, injectors, etc

 

+Pistons, Neccessary hoses, whole wireing harness.

Your best bet is to just trade for a mach

 

It would be much easier if you just bought a used 4v & drop it in.

 

You can't just drop it in. Half the car has to change to accept it. Fuel system is returnless on the current 4V's, diff harnesses all over the place, guage cluster, ecu, clutch, mid-pipe, fuel pump... 2V to 4V is pretty involved. V6 to 4V is about the same.

 

I must've missed something...doesn't have a 99+ Gt? If that is the case you only need to change the exhaust manifolds, air intake & clutch/flywheel *buying a 99+ 4v*. You do not change the ecu, wire harness, guage cluster or even the mid pipe if you want to do a basic swap, fuel pump does not need to be changed either.


You lenghten a few connections on the gt injector wire harness and get yourself a nice sct tune and the car will be up and running. The swap was more involved for my car since I have a return setup so I need a few more parts and I kept my coil packs *but can change later to cop*.

Now if you want more power then of course change the mid pipe add a catback & get an after market air intake setup.

 

Minimal installs like that are loaded with peril for the beginner. Swapping over the ECU, wire harness and guage cluster makes for a MUCH cleaner and easier install and you don't have to pay for a tune. Lengthening wires is adding possible points of failure which the average guy doesn't need to have to deal with. Do you expect him to learn the wiring harness and figure out where everything goes or do you think it might be easier and more reliable if he uses an OEM harness and ECU and maybe a cluster that shows the correct redline and speed?

Why not make life simple and just do it OEM quality the first time? Being frugal and being cheap are only a hair apart from each other.

 

There is no visual difference if you use the gt remaining parts. Why spend extra $$$ when it isn't necessary? I guess if you have the money to blow, but I'd rather spend it on go fast parts. The tune you get from a competent tuner will be better then from the factory. Besides once you start modding the car it'll need to be tuned anyway.

As far as the harness goes there are only 2 wires that need to change, imo it doesn't warrant buying a new harness *which btw are very expensive*. It may be intimidating if you've never done it before, but infact it's really simple. Mind you I have no formal mechanic experience, it just comes from wanting to learn which anybody can do.

 

THR houston did a GT to Mach motor swap. Total cost = $15,000

BUt the guy, (Matt), had a 99 mustang, that wasnt worth much, so it was smart for him to just buy a motor and drop it in.

 

for what it would cost and what you get out of it.. a blower is better unless your engine is out of shape and not ready for boost.

Someone had to say it... proceed with the beating.

 

OMG 15k!!

 

Give me a built 2V anyday...lol

 

wow..haha..im not planing on swaping...i just had the question floating around in my head for a while....


id go the blown root
