    03 aviator engine in a mustang

    Ive been doing some reasearch, and it seems that an aviator engine would be a good, cost efficient swap into my mustang. ive already talked to two guys that have done it and they are dynoing a tad over 300hp with just exhaust. does anyone know if this would be a good swap, and howm any minor things are needed to make this work.

    FWIW, the 03 aviator engine is a 32v 4.6L with the same cams as a mach 1 and has a variable runner intake similar to the fr500 intake. The secondary runners of the Aviator intake are about 9" long, so it sounds like it will make for a very decent performance intake. any input?

    I believe that is what a couple guys are doing at the shop. It is a tight fit and you will need a different hood for the intake manifold to fit but it can be done yes.

    friend of mine back in ny did it. He did it in his garage it was a pretty straight foward swap. You will need a new hood he went with an ho fiberglass 2.5 cowl and it just fit. He made 290 on a mustang dyno with just bbk lts catted midpipe and catback

    wow that a damn good deal. see this might be better than putting a S/C on my car because lets say I buy a used procharger for lets say $3,500, thats already more expensive than the engine w/ warranty, that extra $900 I could use to mod the aviator engine and be somewhat close to the same power lever as the blower (givin I run like 8lbs of boost) plus my motor has a leaking headgasket and has 100k miles on it, my motor isnt going to like forced induction at that point (or at any point). so looks like I might be going 4 valve pretty soon

    Oh and I want to get a cowl hood anyways so thats no problem, I can always run with no hood in the meantime, just to give people the intimidator

    So to sum things up, I get either:

    S/c for my hurt motor for $3,500 + not counting install and fixing head gasket

    -or-

    21k mile 4v aviator engine for $2600 w/ warranty that'll give me 290 rwhp give or take and then mod it with basic bolt ons and get close to blown 2v numbers.

    you also have to swap wiring harnesses and ecu's. That costs a lot as well Alex. Just know what you are getting into fully before taking that leap.

    Well from what Ive read most people that have done the swap are dynoing on/around 300 rwhp. Just wonder if it will be worth the hassle or too much to get into, I dont want this thing to be an ongoing thing where I'll need to make many trips to autozone or junkyard because Im missing a certain part. but if its as easy as some people are saying I would want to go for it
