Subbies are for Subarus, sandrails or Pu$$y VWs! You don't see subbie powered VWs out running the VW power plants.

Subaru is boring
At this point our buggy driver is no doubt 100% insane, to actually build this monster and put boost to it. Yes, a subaru or a rocket engine would be less expensive method of overkill, but this is more interesting Very Happy

Insane is putting a blow through turbo'd 2275cc in a trike that makes 325hp at 15lbs. boost, then hitting over 100mph in under 1/8 mi going up a freeway on ramp with nothing more than a chicken shit bicycle wheel out in front of you... Twisted Evil
Been there done that I have.

But yama's build will throw his ass back in the seat, and hard! Shocked it will be a load of fun, those 2500's are some torquey beasts.

how much boost? where do you get good 90mm cranks?

I have put 30 Lb's to it once. It didn't like it so much.
Typically I run about 22 but want this build to survive a little longer so probably keep it around 12 psi.
This one is an old Bernie Bergmann Crank that is no longer available.
If I found major fault with it I would have purchased a new one from DPR, DMS or Moldex. They all make them.
Moldex, if the budget allowed, are about $2K

This is a VW site.
Take your Subaru garbage and wiener budget somewhere else.
Max potential cost real $$
Pulling 9X the HP out of an original 50 HP engine is like taking a Chevy 350 and making 1800 HP. How much do you think 1800 HP would cost to build and keep alive?
Not mad; just getting you to think diferently.

Any small block can make that if you throw enough nitrous at it, getting it to make that consistently and reliably will take around $50,000. Wink

I get great satisfaction beating modern cars with a engine that was designed in the 1930 and maxed out at 58hp originally.

And able to do it day in day out for years.

I love the smell and sound of a air cooled Type 1 engine.

Nothing wrong with a Subaru, but it isn't a vintage VW.

If you are doing the tuning YOURSELF,then check this system out.

www.sdsefi.com
I have used this system on over a dozen cars. It is SIMPLE to tune and RELIABLE. Much more intuitive to use than the laptop systems.
With this system on my 2.0l VW 16V with a GT3076R turbo I made 445whp at 28ps,and on a 2.8VR6 made 463whp @ 20 psi with a GT40R.
This system is USER FRIENDLY,and is easier to install than a car stereo,and the keypad makes tuning so simple it is ridiculous.
Good luck!
