Type4 Newbie wants to build one..?..., Scary or dive in!? Options

[2mAn]

Hey Everyone,

Been considering buying a Type4 "kit" and building one up from scratch. I recall theres a book thats been suggested to use, and wanted to know what you guys think.

I have contemplating doing this for a while now and figured I would see what you guys think. This would be a side project with no definitely timeline as the engine currently has no home and would be a problem for future me.

So, what do you think? Any suggested books, tools, etc that are "must-haves" ?

Thanks!

It’s everything.

The 103’s and a few other issues were covered by Ninja. The problem is air cooling is completely different than water cooling and heat rejection is a constant issue. Nickies solve the majority of the issues but they are crazy expensive and I’m sure they aren’t in the parts you’ve referenced. Nickies alone are about $4.8k+.

Building a stroker brings along its own issues that I won’t fully cover here but as you increase stroke, you drastically increase centrifugal forces and piston accelerations that aren’t completely addressed despite balancing. The T4 is basically a 3 bearing crank with two cyclinder throws between each main bearing. Not a problem at Stock HP and RPM’s but start stroking it and increasing RPM’s and cranks break.

Then there is the lightweight flywheel and its potential pro’s and con’s.

One of the main issues with T4 air cooled engines is everyone thinks they are easily hot rodded and they can get magical horsepower. . . But HP = heat. With air cooling limitations it’s not easy to get rid of the heat and the thing becomes a grenade.

Would highly recommend sticking to a 2056 build using 96mm pistons.
