I have a 1998 v6 3.8 liter motor in my mustang, I want to swap it with a 1998 cobra motor what will i need and how much will it cost and where can i find the parts for this swap please help thank you for the help

 

Your best bang for the buck is a 4V 4.6 Lincoln MKVIII engine from ebay or a junk yard. It is the same engine as the 98 Cobra but ALOT cheaper because people have no idea how small the difference is, small differences like cam lift, and the intake manifold is different. People do this swap and just put a Cobra intake on the mark motors. ANY 4.6 T5 will hook up to it unless u want auto which im sure you can find with the engine. IVe seen these engines go for 600-800 bucks. Labor to drop the engine in would be around 1500ish dependong on where you live. You can have your current ecu tuned or grab a mark ecu. You will need to ditch your current drive shaft though and grab a new X/H pipe and cat back. Your rear end will be fine till you blow it. GL hope this gives you some insight to get started.

 

my friend works some where where they get motors all the time so he gave me a good cobra motor i have a t45 tranny on my 3.8 already so all i really need is the motor harness and do i need to change the motor mounts?

 

You need motor mounts and a k frame from a 96-98 4.6l, the 3.8 kframe is the same as the 5.0

 

3.8's have a T5 NOT a T45 which is what you need...

no need to grab a new shaft just swap out the yokes for a 31 spline instead of the 28.

k member needs changed

get an 8.8 rear ditch the 7.5

96-98 ECU and harness

96-98 Cobra intake

a few other thing im sure
