Jaems,
A good read. You know your stuff. Like everything POLO's have morphed over time. From 2800 to 7200 with your foot in it, it's hammer time. Bob stroked it from 2000. When I reference cruising in the 2500 to 5000 range, that's just puttering along in city traffic.

Chris, could you post this to your site...Â* reSee Works​previously Pompolo Design - Home

I have a one word exclamation to describe your 4 cylinder car,

Z O W I E E E E E.

Passing me the key to your car on my recent visit to Denver and letting me go for a hooligan drive was outstanding. That engine pulls so strong it is just amazing. The run down the road with the signal intersection under the roadway presented a less than desirable condition with me making the on ramp light - but caught in a low rpm condition in second gear - with a blend lane filled with a truck I just had to put my foot into it.
The gearing and the power that 2.4 engine puts out, yup, zowiee is the best description. It pulled from just below 2000 rpm to well over 6000 in a blink of the eye, sat us back into those wonderful seats and propelled us to a exceedingly unlawful velocity. I really didn't want to back out of the throttle.
Rarely does one get the chance to experience that thrust.

I have to thank you for putting a highlight on what was a truly wonderful experience in Denver... old 911's...great folks, and your hot rod.

Smiled for the rest of the 2000 mile drive, thanks to you.

with that old 1964 911.

Bob has compiled a list on all known 1964 911's and just sold his #149 car in Monterrey a week or so ago. He is now restoring a 67S.
He was in Denver to inspect the #133 car at Vintage Car Works. The #133 car went to the Quail and might make it back to So Cal for a showing 9-14 or 15-2013.

I ended up buying this used FAT Performance 2.5 L Type 4 for my '68 912R build. It was previously owned by 914 Collector Ron Light of Hershey Pennsylvania.

This is the motor that was in his Bahia red 914 2.0 when he recorded the faster Porsche time for the Hershey Hill climb.

Ron [age 75] lives at the top of the hill at Hershey so he's done it for well over 30 years.
I think he said the time was 50 seconds.

Chris, this Type 4 revs like a mother.

Ron Light just talked to me on the phone and explained it was a very quick car. I'll believe the HP claim after i drive it. I do believe it runs nice having spoken to multiple people that have driven the 914 2.0 it lived in prior.

John Forbes Owner of the very reputable Black Forrest Racing in NC, looks after the Bahia Red 914 2.0 that now has a flat six engine installed in it.

John drove this 914 plenty before the Fat Performance motor was removed and told me it ran real smooth and idled nice.

Also a great guy named Brian who runs a Porsche shop across the parking lot from Black Forrest Racing drove it and said it was quick and that the cam really comes on around 5000 rpm. He said he had that 914 2.0 doing 120 mph very quickly.http://forums.pelicanparts.com/uploa...1476754108.jpg

That engine in your 912 will be a blast for sure.

Taking it apart to see what I've got. Has 2.0 Porsche designed heads, valves look big but I want to confirm all this and the actual displacement. I also want to hone the cylinder walls for good measure. Looks nice and clean so far. This motor was built 10 years ago at least so it needs detailing and freshening, but i bought it very well. New [after a core credit of $1000] they run around $12000 for 160 BHP and go up from there.

The shroud is red gel coat finished but has been painted black. It has some big chips and a few small cracks which i want to address properly with fiberglass and then paint it properly. Then detail the rest of the engine. It had an oil cooler mouted in the frunk of the 914 2.0 which i need to replace but will install up in the fender in R fashion. I'd like to do 2, one in each fender and install an Accusump.

The serial number on the case begins with a G, all Type 4 cases are the same but that means this one was originally in a Bus.

I'm thinking i need to add some Hippie aestetic details. Maybe 7 dancing bears in place of the PORSCHE script on the engine lid.

I wouldn't mess with building a VW engine until you pickup the 912. You may not need a engine. They are worth more with a original 912 engine.

Good morning everyone, keeping it all Porsche., Porsche can be looked at from a cash reserves bases.

You could mothball the 912 engine, for numbers matching authenticity, and go TypeIV. Looking at it from cost, give yourself a max reserve. You will get a lot more done for the amount spent, if you choose TypeIV. Doing so, may corrupt the purest ideal. You will need to make a decision. Dollars will ring out either way. Going faster will cost, I'm not done with my TypeIV and have spent will over 13k. A good exhaust,let say one from A-1 will cost 1500$. Or, there's the Tangerine exhaust system,if memory serves me right, it's around 2500$.

Let me be clear, I'm not trying to scar you, just giving you an heads up. For the type IV head work is about easy 2k, that's if you sopply the core.

Please make the choice, and jump in. I don't have a Porsche:-(, my engine would be better suited in the Porsche,from the dynamics that the Porsche body style offers.

You are on the right track.

Customizing Porsche's = $
I have 4 years of a Private college education in mine. As we were unable to have children I could spend the money on the car. Smart? Probably not.

Just bought a 1969 912 with all running gear but missing the engine. Have a type 4 on the shelf. Was going to rebuild it with this kit

https://aapistons.com/collections/engine-rebuild-kits/products/vw-type-4-performance-plus-engine-rebuild-kits

Then install it in the car. Came with brand new webers and manifold in the box. Have all the 912 tins. What else would I need to make this work?

Type 4 in a 912
 
I’m also installing a type 4 2.0 in my 66 912. What you need to do is if your 912 engine is a 5 speed then you need to obtain the 5th gear from a 914 trans and install in place of the 5th gear in the 912 trans.

These kits are ok and many use them,however European Motorworks have better offering for all out performance and longevity,a T4 motor properly assembled with the right parts can yield good H.P.
Head replacement with the new casing go's a long to helping issues with old worn out ones which in most cases aren't worth repair,they benefit from a good flowing exhaust also,when you go large displacement you will need a front mounted oil cooler because the stock cooling system is somewhat marginal.
Not a cheap solution but if all is taken in to account they are a strong motor.
Good luck.
