I've been up to scratch building recently, specifically off-road vehicles in 1/25 scale. Over the last few years, Heavy Arty and Trisaw have commented on a few of my projects to check the FAV out. It's an interesting high speed, light weight vehicle based on off-road racing technology:
I'm sure many of you have seen the image above. As an off-road racing enthusiast, I've long been interested in this vehicle. As I did some research I found that vehicle users noted these were under powered which limited their value. They were equipped with an air cooled VW engine - which is fine for off road racing purposes which include one or two drivers, and little else in terms of storage, but not great when you add a passenger, weapons, and gear.
Nonetheless, I was going to build this with a VW engine. I didn't though, as the 1/25 versions of VW engines I found simply looked anemic - and I couldn't figure out how to faithfully build one up to reflect at least some power modifications.
So, instead, I looked into the SCORE International rule book for specs on variations of the buggy class and discovered Class 10 which allows the use of among other things, higher powered engines - like the GM EcoTec, and Ford 2.4l engine (used in some Ford Rangers). While I couldn't find either of those, I did find a Nissan engine that includes a trans axle - which is perfect for a rear engine, rear wheel drive unit - as an example, see below:
and while I was at making changes - new rear suspension, as below:

and modified front suspension, as below:
Below, you'll see first WIP, then built:
As you can see above, the fit is tight, but believable - and not that far removed from the original - and below, a bit more done:
and with some paint:
And there you have it - a fun build -
thanks for checking it out!
Cheers
