To build a 100hp reliable aircooled engine will cost $5000 in parts alone, I should be able to convert and engineer this for that price.

Yeah beetle engines are ridiculous prices. We got quoted $3500-4500 for a stock 1600 for a reliable 65HP :rotfl:

EJ swap sounds good. What motor is that? DOHC & funny looking manifold
 
A Beetle with 100hp :huh:
I'll be looking forward to seeing that once it's finished :twisted: :biggrin:

Your absolutly right stilson.
For my Manxstyle VW pan based buggy I build a aircooled type 4, 2 liter engine with 40mm weber carbs with 98hp at 4.000rpm and 175nm at 2200rpm at the dyno. Cost me just as much to build as the amount that i spend when i bought my subi.

If knew all upfront then i would also use a subaru engine. My buggy is a sensation to drive when the engine is running propurly, but the weber carburators are a pain in the a##.

Keep us posted!

Later EJ25. ~05+ use that manifold. Not sure if they are dohc though so the pic could be a turbo ej205/255

The MY06 Forester onwards (EJ-253) don't use DOHC. Strictly SOHC. AFAIK, only US N/A EJ-25x engines way back used DOHC. So if the donk is sourced in Oz, should be out of a turbo ... maybe :iconwink: :lol:.

Could it be out of another model? Impreza? Liberty?

ST can tell us ... :).
 
So can I. Earlier model Lib's came out with 2.5 quads.
 
Sheer lazyness on my part, that was just a google image, will update thread with actual engine (SOHC EJ20 from 2001 SF) shortly.

DOHC would require more cutting than I am prepared to do.
 
I'm planning an IRS swap to maintain rear wheel geometry through the range of travel. Hoping to pick up a wrecked superbug and cut and weld the mounts on.

The real question is do I use the 4 speed VW box with the adapter plate and custom flywheel etc or use a subaru 5 Spd with a reversed ring and pinion, awd lockout and blanking plates.

5 gears would be nice (and stronger) but it jacks up the cost. Subarugears.com has the kits for $2200 or a recond converted box for $3500. Off topic, if anyone is looking for centre diffs they would have them in abundance I would think!

The other obvious issue is where to mount the radiator. Most put it up front but I really want to keep all the weight to the rear of the car and also not lose storage space in the boot/hood/trunk.

Thoughts?
 
Use an original beetle irs transmission. If you don't do burnouts they last long. Take the one with the longest gear ratio and use 205/65/15 in the rear and it wil go like a rocket. If you want to have it bullet proof than a vw transporter trans. But that aint cheap.

i use a stock beetle trans with the shortest gearing with 30-9.5-15 bfg tyres and it allready last 3 years with a lot offroading.

were are you gonna place the radiator?
 
Amazing. Ideas and thoughts from all over the world... all coming together in this forum!

Just goes to show if you can think it or dream it... somewhere in the world there is somebody else doing exactly the same thing!

I really should have posted my Husqvarna problem in this forum, would have saved me a whole heap of angst!

Best regards,
 
Thanks Casper, I'm running 31/10.5R15 on the rear.

I'd love to get the rad under the deck lid (with leading edge standoff) in place of the old tinware with thermo fans.

I stayed up til 4am and I've found an IRS rear end for $130 and a stack of Type 2 boxes from $50 up. I'm not kidding myself, a bus transaxle swap is a massive project in itself but it would allow me to use an RJES bellhousing (£470) instead of the adapter plate custom flywheel *******isation. Then I would have standard subaru flywheel/clutch components. Another positive is obviously the extra strength and higher ratios.

What are your specs mate? Got any pics?
 
31's in the rear thats huge! What kind of fenders are you using? Baja style?
Maybe an idea to place the firewall more forewards? If seen some do that before.

I would definitely go for a bus trans for that price. A bus trans is a little slower in shifting then a beetle trans but they will last. Wy not go for a subi turbo engine? If i had the chance to do it over again then i would go that route.

My buggy has a full length vw pan, an apal fiberglass body, AT tyres, type 4 2 liter engine that i build my self with an 296 schrick cam bigger valves and a type 1 colling fan in a fiberglass housing.
I own it now more than 25 years, geee i am getting old! :eek:

my wife likes to go with me in the buggy in the summer time if promise to drive normal. She doesn't go with me when i go offroading, has something to do with my drivers habit :lol:
she does go with me when i go with the fozzy.
 
Sorry Casper, I just checked my tyres and they're only 235/70 so 28/9.25, don't I feel silly.

I'm not going turbo because of size and cooling constraints (trying to keep all the sheet metal I can), and 126HP is plenty of power for a 700kg car.
 
Most pressing question is of the two bus transaxles I'm looking at one has Porsche flanges on it. Should I pay the extra $50 for it?
 
I say why not, go for it :)

If you're (potentially) spending that sort of money already, whats another $50 :cool:

Regards
Mr Turbo
 
Perhaps the Porsche flanges were to use the Porsche axles to fit Porsche wheels. Depends what wheels you want to use, not a lot of choices with bugs.

Personally, I'd keep it VW
 
porsche cv's can work under a much bigger angle then the VW cv's. Ideal for offroading but overkill for street use with 120hp.
