I bought another car... A Porsche 718 RSK Replica built on a space-frame chassis with a mid-mounted VW Beetle 1600 Twin Port engine with the 4-speed gearbox at the back.

I've been interested in getting a 550/718 replica for a while, and this one came up for sale from a friend's gf's dad. He built it with the intent of racing it, but never got round to it after being put on early pension due to medical reasons. It's running a swing-axle at the back with custom suspension with coilovers, with ball-joint Beetle suspension in the front with Bilstein shocks. It also uses '67 Beetle disc brakes up front, with standard Beetle drums at the back.

It's a hoot to drive, although slow thanks to the Beetle motor. The thrust bearing came off the fork as well, so I took the gearbox off yesterday, got a new thrust bearing today and am busy putting everything back together.

I'll look at how I can get more power from this motor, or what other engine options there are... I like the air-cooled motor for this, but need more power.

R118 for the thrust bearing and a few hours of graft and it's back on the road. One thing I like about this thing is it's probably the simplest car ever. I basically fixed it myself with some assistance from a friend who is even more useless than me with a spanner. I foresee lots of joyrides ;)

Sud motor would be nice, but it's water-cooled and there isn't lots of space for plumbing in the front. 2 liter Kombi motor, they are heavy beasts. There is a 2.1 liter Kombi motor which is water cooled lying at Trackman's house, which will probably be the cheapest option of going more power now... but also heavy and water cooled.

I remember some guys put the radiator in the rear... with some issues. While googling I found the following link with engine options, it might be helpful for you: Why Subaru Engines?

The twin port(per head) engines can be work quite a bit with a twinchoke IDA Weber(or two injectors) on each bank. The 1600 is the long stroke motor and there where a 2.4 ltr sleeve kit for those in the '70s.

They are very light. The best handling one I saw had a defuser under the nose. A meter long, meter wide, 40mm high funnel with 50mm wide partitions running through it.

I looked at the RSK kit long ago. For my the let down was that there is no way to get a top on it and then get into the car.

Scat etc make/made great stokers, your wallet thickness (as always) determines the limit on performance from the air-cooled motor.
