type 4 engine questions compared to type 1

I'm building a couple of baja bugs, and in my travels I found a guy with a bunch of interesting stuff.

One of the things he has is an engine/trans out of a 1975 914. The engine is "complete", except no carb. it does have a spider looking intake manifold. The engine does turn over, and I'd bet from looking at the rusted out junky car the engine probably runs.

How much does a type 4 engine weigh compared to a type 1?
If I say a torquey 1835 type 1 makes 100 horsepower, how much hard would it be to make the type 4 engine make the same power?
if i swap it, do i use a type 1 flywheel, or the type 4? starter?

how much is the upright cooling conversion, and which should i use?

thanks

hmmm.
google shows 50 to 100 pounds heavier, depending on exhaust.

maybe a type 4 with hotrod exhaust is about the same weight as a type 1 with heater boxes???????

google says stock the 2 liter as about 100 horsepower, with 106 torque at 3500 rpm.

wow.

Nearly ever question is answered here; http://www.tunacan.net/t4/
But think flywheel, exhaust system, intake system, upright shroud and a comprised heating and defrosting system.

Actually if I remember, it is 25 lbs more then a T-1. Be careful, that is when they are converted to Uprights.

No heater boxes , exhausts are about the same you still have a crank, flywheel clutch, they just weight more, so, ok 25 to 30 lbs. That is the reason why a upright converted engine does not need a rear support, just bolts up like a T-1. A stock t-4 for sure needs support with the big aluminum blower on the ass end.

I should have posted back...

Thank you all for the great links.

I've been reading, and thinking and talking with folks. I now have people trying to give me engines and type 4 parts.

my first engine is a 2 liter from a 914, year about 74 or 75. I paid a favor someday to a good friend for it, but then later he came and repossessed the intake manifold and a 2 barrel carb i had.

So , then I went and "stole" a set of dcoe's I found in his junk pile, a shroud, fan, and alternator for a 911.

Next step is figure out a cranks shaft pulley, make a conversion bracket, and mount a type 1 generator or the 911 shroud.

If the carbs you picked up are DCOE's, they won't help you much; DCOE's are side-draught carbs... you need to be looking for down-draught Webers... like an IDF or IDA series. And conversion kits are available for converting the T4 to an upright configuration.

Joe -

How much does the 'ass-end blower' weigh?

That big aluminum blower with fan is about 12-15 lbs. Its magnesium.
The type 4 case is heaver and longer....with a longer crank and an aft mounted alternator. Thats why it needs a rear support bar,.....that and it really depends on the transmission type. For the automatic....using any non rear supported engine ...type 1 or 4 will do damage to the pump shaft. In the 411/412 cars the hanging engine will also damage the main shaft in the manual 004 tranny. Its not an extra huge weight difference. Its that its spread out over alonger length creating a greater cantilever. Ray

the carbs i got were the big downdraft ones. they came off a 914, so i'm sure they will fit.

this is going in a baja, and i really don't think cooling is going to be an issue. Also, money is really tight for us.

I have been fitting different shrouds, and it sure seems like a guy could make a simple steel mount for the generator I have, and mount a type 1 upright on it.

I know you can buy the kits to do it, but the kits seem to be over 300 bucks????? Is there a cheaper alternative?

Raby's kit for sure looks the best, and he sure knows the engines, and I'm sure his cools the best. I just cannot afford it.

Dstar, nice to know you remember me, ha!!!
Dmiller, if you have some T-1 and T-4 parts and you are handy you can do it for nothing. If you buy some bits then of course the price goes up. But I figured a while back even if you had to buy everything it still would be under $250

Go to my site and buy the manual. The $29.95 will save you alot of pain and money.
