Author Topic: Having issues sourcing parts for a 4g63 swap... Any better I4 options?  (Read 2324 times)

I love DSM, but just like finding go-fast parts for the FC, finding the bellhousing I need to use the Turbo Trans is proving to be impossible and it seems like a lot of shops that specialized in 4G's are mostly gone too... the few I have found seem to be inactive or aren't interested in building a longblock.

There's plenty of newer Ford 2.3 Ecoboosts Mustangs around here that have been wrapped around poles, people, signs, etc or have been wrecked cause people decide to drive them in winter. Has anyone done this swap yet?

Any other suggestions? I was also thinking Honda K24, but I'm really not a fan of how they sound.

Current goal is 300hp with room to upgrade, mainly for AutoX/HPDE/Track-day/Weekend use.

Maybe some kind of 5 cyl? Volvo or VAG? Otherwise I'd have to say a k-swap is a great option. Hide the sound behind a turbo.

Just about anything sounds better than a 2 rotor. So, it'll still be an improvement. A Honda K series engine will be your best intersection of performance, cost, and ease of swap if you want to go 4 cyl.

Yes.

Would an ecoboost 4 cylinder and transmission fit fine in an FC? would definitely be more unique than the K swap.  I also think a beams swap FC would be cool too

I bet you could get F20C and 6 speed from an S2000 for cheaper than a K24 and all the required swap equipement. The trans adapter, oil pan, intake, coolant reroute stuff, etc. adds up fast.

I like this idea.  Those motors, with some basic mods, can make serious power.  :bacon:

The Ford 2.3 Turbo in the Ecoboost is likely a good candidate. Because they are rental car engines and found in many other ford's they are pretty cheap.

I have a '19 Ford Ranger with the turbo 2.3 and 10 spd automatic.  Even stock it rips.... probably runs a low 14 second pass as mine is 2wd with an aluminum flat bed (600lbs+ lighter than 4wd).  With a 93 octane tune, downpipe, and 8.8" out back for the gear ratio options in a 2800lb RX-7 it would be running 11's is my guess.

I think in Automatic trim Ecoboost mustangs with just a tune and sticky tires pulled 11s 1/4 mile. Tuning them takes them to like 400 WHEEL tq. which is nuts.
