Ideas for swaps other than a V8.

oorx7 · 03-10-2008, 11:58 AM

Personally I am panning on using a 4g64 block in a FD.

What kind of swaps have you guys seen or are doing?

The only swap I have personally seen besides the V8 swaps was an SA with a 4.3 Vortech V6...actually was pretty quick little car, but not my cup of tea

The chassis that I will be doing a swap on, will be solely used for autocross/road course racing.

One of the swaps I have thought of performing.

Boxer flat four:

The Good; good torque, sits really low in the chassis, fairly light because its aluminum, and might mate up to the RX-7 trans.

The bad; Replacing miner things such as spark plug would be a choir, not as Stout of a motor than other options.

Never thought of that one...but it seems like side clearance would be an issue

The Phantom Gallon · 03-10-2008, 12:31 PM

yeah, how wide are those engines?

i'm sure it will fit, but it might be pretty tight. Trans mating might be an issue.

I wouldn't do it on an FD, but still have always thought 2.3l Turbo Ford powered FC would be neat and Granny's already has the mount kit available. Bulletproof engine, takes crazy amounts of boost on stock short block........Only down side is the weight.

I measured it up, and unfortunately it was on a piece of paper that I can't find ATM. But there was only about an inch of clearence for the the head to the frame rail on each side, IIRC.

The nice thing was, you just about fit the whole motor behind the shock towers. The idea was to run two small turbos, one on each side. Then mount them in the front, with a V-mount cooling setup.

Same thought I have about the 4g blocks.

Might want to do some more research

Stock blocks/cranks are fine, but pistons and rods are junk. Crack-free heads are drying up. A fully-dressed 2.3T also weighs as much as a 302 (which means it's MORE then an LS1). Good motors, but the market has come and gone on them. You'd have better luck building 12A's or nailhead Buick's honestly...

My daily driver is an 89 GTUs fitted with a 3.8V6/T5 combo out of a 98 Camaro. Not a powerful swap but a bit faster than a stock TII, gets 30mpg, and serves well as the weekend tracking car when the V8 car is out of service. There is a pic of it in the 2nd gen. media section.

My bad...I had a 86 XR4Ti I just sold. When I got it about 4 years ago, most people thought the 2.3Ts were still the shit, but its been a few years since I seriously looked into modding them cause I got the RX instead and my sister started driving the Merkur.

There is a thread on 7club that details a Nissan KA24DE swap into a FC. I'm not sure what the status is, but here it is: http://www.rx7club.com/showthread.php?t=542285

Also you could swap in a Toyota 3SGTE from a Celica alltrac (GT4), MR2, or Altezza. I know TRD has been using the 3SGTE in the GT500 class of SuperGT to power the Supras.

What side of the motor is the exhaust on, I cant seem to remember.
