2v to 4v Swap

97aztecgt · Nov 13, 2008

There was a thread on here, but I guess it got deleted during the melt down. Anywho, I was looking for some information to convert my 2v to a 4v...

I have no idea where to start or what kind of parts to pull off of what year make and model cars. During this time (if my internals aren't built already) I will put forged internals in as well. I'm looking to make roughly 5-600 after a SC set-up as well. Some info on parts and anything else would be wonderful! :notworthy:

i thought you had forged lower internals? if so b heads off a cobra or mark VIII and cams. or c-heads will work. cams are a choice. youll need an upper/lower plenum. run a couple wires and should be good.

Supposedly I do, that's what I was told when I bought the car. When I get into the car and I see that they are stock then I'll just get the internals and do the car correct the first time.

Which year Cobra would the B or C heads come off of? Is there a company out there that make aftermarket heads for the 4v? What exactly is a couple wires? For the plenum, what year should I look for that off of?

Sorry for so many questions, I'm a 'noob' with Mustangs.

b heads off of mark VIII heads off a 93-95. after market heads for a 4v. i am not sure. c heads if i am not mistaken are off the newer cobras. i think the 03/04. might want the plenum off the termies. if not the 01 cobras will suffice if i am not mistaken. the wires are for the maf/iat integration.

B head's through 98, 99-up C heads, 03/04 Cobra heads, are 03/04 CObra heads. GT500 and GT heads are also slightly different.

B heads require a 96-98 Cobra intake, the others, Mach 1 or 99-up Cobra intake. Easiest and cheapest to get B head stuff.

Is there a big difference in heads (performance wise) between B & C heads?

that i couldnt tell you. im stuck with the NPI goodness for the moment.

97aztecgt · Nov 18, 2008

haha... I gotcha.

I'm gonna start calling up local jy's to see if they have any Cobras. muahahhahah

Some people get all caughht up in flow numbers, and if you were trying to make 1000 rwhp and go Renegade racing, the differences would matter, but either will make more power than you're honestly probably going to.

97aztecgt · Nov 18, 2008

So, I need the following...

*Heads 96-98
*Cams: Do the years matter?
*Intake 96-98

That's what I have came up with so far. Anything else?

Also, just another random question... Do we have long or short blocks in our cars? Differences besides the obvious?

my 97 is getting and 03 mach 1 motor and procharger d1sc this winter. so im going to use a complete 4v ecu and harness but if your going to just go with the 4v top end then here is a link that javi sent me that should answer alot of questions about using your 2v harness. http://forums.corral.net/forums/showthread.php?s=&threadid=515940&highlight=return+returnless
good luck and let me know if you got any other questions

Longblock means, engine minus intake, with heads/cams

Shortblock means, engine, no heads, cams or intake

I was told timing cover and chains along with a couple random brackets here and there.
