03 Motor swap what'll it take

[98GTBlk]

I have a 98 GT and as you know a 5 year old could beat my car on his tricycle. I was for a while thinking about building the 2v under the hood but decided it'd be easier and better just to do a 01-03 cobra motor swap. Id really like to get the 03 cobra motor under the hood. What peripherals will i have to change to get it working? such things like electrical or ecu, or suspension.

Well first before you look at whats involved in the swap; Are you prepared to pay the $11,000 for the 03 cobra motor complete with computer?

FRPP's 4.6L engine assembly is a pretty good deal for $5,995 (also one other for $5,795.

even if 03 cobra engines are nice...they are way too pricey..I'd rathe rhave a built forged engine under the hood for less money

 

[98GTBlk]

where are some good sites that build forged engines complete with superchargers?

I would go with #1 or #2.
SHM is pretty pricey.

A less miles 4V would be a good swap also. Consider STANGPARTS and sites like that.

Why is that motor on the FRPP site listed as "not legal for sale or use on a polution controled motor vehicle?"

High emissions output.

Ideally supposed to take it and leave it on the race track only. It's only way for a company to get around the legalities of selling an 'illegal' engine to a consumer who will obviously drive it on the street anyway. They're just not responsible for what the end user does with it.

Same with "offroad" mid pipes.

Word is.... these motors were for a racing school. Leftovers so they aren't for on road use, but, that can be changed via chip.

ive come across the 5.4 engine on the frpp site. Whats ur take on going this route instead of a 4.6.

Just get a forged and built long block for a 99+ gt and pop on either a pi intake or a bullit intake and get a vortech jt-trim or a paxton novi 2000 and get either a SCT tune or a EFI solutions tune. Good exhaust with long tubes.

A good forged 4.6 short block will cost you $2,600-$4,200
Heads will cost you $1,600 to $2,000
Cams $450 to $600
Exhaust will cost you $500-$1200
Tune will cost you $300-$600
Supercharger kit will cost you $3,000-$5,500

I didn't really include labor on all those prices, it just gives you an idea
Prices include what route you choose. But that combo will give you a ton more power than a stock 03 cobra will or even a bolt on 03 cobra with the stock eaton s/c.
