now, speaking of "mo power" ...

here's something out of "the book" (page 12):

in 1949 porsche was commissioned by the italian Piero Dusio (owner of "Cisitalia") to build a racecar for him.
the car was a midengine tube-frame car based on porsches P-Car concept.
it featured a 1.5L (yes, one-point-five), 12 cylinder flat boxer engine with 450HP @ 10500 rpm.
it had 4 overhead cams and dual weber carbs and a roots-compressor ...

top speed was 300 km/h (~190mph)

now THAT sounds like a fun engine (IMG:style_emoticons/default/wink.gif)

There have been 3 or 4 turbo 914s that I know of. SammyGs, EdEvil's, Jeff Shuys and one other...

I would run one now with Kit Carsons EFI so you could keep it running cool on boost.

money, that's all it takes. how could you do that and not swap the engine? you will need a new clutch anyways.

Jim,
Welcome to the 914club.
My current 1.8liter race engine puts out about 150hp peak, but it's pretty lame below 4000rpm. It shouldn't be too hard to find 120 hp from a 1.8 liter engine, in a package that will be streetable and last 10,000mi or more. It will take a few extra sheckels to do it right. Carbs and exhaust, as well as some dyno tuning should be part of the combo.

Ed Morrow has a turbo 1.8L that has some good kick. I saw it and had a ride in December, and was impressed He lives not too far, near Sturbridge Mass.

Guys, anyone know how much a turbo would run ($$)

how much power could be added with one.

Has anyone actually turboed a 914 and what does the project entail.

if you have to ask ... (you can't afford it)

okay - more realistic. picture your worst-case high-water mark, double it, and you'll be in the ballpark. the power is the -beginning- of your issues. for every HP you make, you must deal with 2 in heat rejection. cooling is a major factor. your transmission was designed for the power available. double the engine power, and things downstream start breaking (later, if not sooner).

race sanctioning bodies factor turbos at somewhere between 1.4:1 and 2:1, typically. so figure to double your ~90 HP - tops.

a few have. at least 2 were running. one quite well. a few others in the past. it's not trivial, although with the (recent) advent of reasonably-priced, programmable engine management systems, it's probably easier than it ever has been. (at a cost - figure somewhere between $1k and $2k for induction/engine management. at least that for appropriate exhaust. you'll need a turbo. and lots of oil cooling. and ...)

Porsche made its reputation by beating big-engine cars with teeny engines, brakes, and handling. After 20 years of trying, they finally won Le Mans with a 4,5-liter engine, just like the competition they were trying to beat.

OTOH - if you -really- want to succeed at the Stop Light Grand Prix - go buy a Hemi-Cuda. power is fun, but when it comes to spending your hard-earned money - decide what it is you -really- want first.

Man this is good..LOL

5k for the turbo setup with all new injection system or 7k for a 2270cc engine carbed. Plain and simple. You will not get 140 out of a 1.8 without spending big money. It will cost the same to get 140 out of a 1.8 as it would to get 180 out of a 2.0 (minus the core engine)

When people walk into the shop and ask.. I just rattle off the cost. I dont even go into all the variables..its a waste of time.

What are you planning on doing with the car? Racing it? or just street? What are you looking to spend?

This will help these other smart guys help you decide.

I figure the best way to get reliable HP out of a 1.8 is...the VAG 1.8T engine (IMG:style_emoticons/default/lol3.gif) They put out 225HP in some factory configs with full warranty and streetability. Much more with bolt-on mods.

I know some of you guys are big fans of the Type4 platform, but I'm just not.

I'm a big fan of all of the engines derived from the original bug engine. Especially the Subaru motor I'm putting in my car :-). The 6s aren't bad either - although a bit heavy.

If I was going to do anything for more power than a TIV could put out- I'd jump straight to a small block chevy! The engine is dirt cheap to build and a two year old can do it.....

-6 is way too damn expensive!

... 200+ can be done!

read the original requirements - no engine swap.

200 can't be done on 1,8 liters as we know them ...
(forced induction is another matter. this is no simple matter either.)

my bad, I thought by "original engine" it could still be bored and stroked... I thought he was just trying to keep it type IV powered... I'll have to read more carefully next time (IMG:style_emoticons/default/smile.gif)

There was an article in Excellence last year on a turbo 914, sweet car, does anyone remember the month this article was in? It had the MSDS turbo fan cut into the back trunk..

-I seem to remember that the guy spent well into 5 figures to do that job....

I think they are talking about the six cylinder turbo in Excellence last year.

My Turbo Type 4 was in the June 2002 issue.

Check the webshots link in my signature, the Excellence article is scanned in there.

Also a new album on a friends 914 that I'm doing a Glass GT kit and full repaint on.

Regards,
Ed
