Full Version: Turbo Type-4 912 Project Update

Britain Smith
With my move to OR less than 30 days away, I am on the fast track to getting all the machine work, painting, and parts gathering in the Bay Area completed. This weekend, I was able to borrow Randal's trailer (awesome trailer, BTW) and take my car up the machine shop where my engine is and fit the exhaust from the turbo outlet to the stock location on the car. I also fab'ed up the wastegate dump pipe and finshed up a couple of odds and ends. The header that Marty Staggs built had to be cut in half and extended because the motor that I supplied him for fabricating the headers was a stock block where as my motor is a stroker motor with low compression and therefore is a bit wider. Here are a few update pictures along with some bling, bling from Marty.

awesome!!!

Very nice drooley.gif ....I notice that the intercooler and manifolds are "fixed", any concerns with thermal expansion of the motor being greater than that of the intake assembly???


Britain Smith
I have thought of that, but from what I am told it shouldn't be a concern. Everything is aluminum BTW, including the cylinders. If there is a problem, then I will put Silicon rubber sleeves on each intake runner.

any concerns that the header, being soo close to the rear apron, may fry some paint??? header wrap maybe?
Britain Smith
Everything will be ceramic coated.

I love a good turbo charged porsche. Looking good.

Really great looking assembly work. Couple of questions though, how much boost are you planning on running? I noticed that there are stock valve covers and they sometimes leak on a normally asperated hot rodded 912 engine, do you think they'll seal well? Also I noticed the larger wet sump and I am curious if the high crankcase pressure might keep the oil from coming back from the valve area? Sure looks great!

Lookin' good. I like the wastegate dump pipe.

He has some fancy HEAVILY modified valve covers for it. Those are just on there for mock-up.

To address your concern:

1. I have a set of modified stock valve covers with oil squirters to keep the Pauter Roller Rockers lubricated. I am not sure if I will have sealing issues, but will cross that path when it comes up.

2. As for the crankcase pressure, since I am running crankfire ignition I do not need a distributor. I therefore has a piece of aluminum bar stock machined down to accept a distributor o-ring seal and welded an AN-16 fitting to it. This will serve two purposes, to help the case breath better and to provide a place to fill it up with oil. I also have AN-12 lines coming off the valve covers.

With his breather setup, he will have NO crankcase pressure to speak of. wink.gif

The man has all the answers. Good stuff. Not just a look good car but a well though out one too. Who would have though and all this from a porsche guy biggrin.gif smilie_pokal.gif smilie_pokal.gif smilie_pokal.gif smilie_pokal.gif

I think that's enough already Britain! Eveybody Knows you can't turbo a Type IV wink.gif . Everything looks BADASS! Isn't it Marty who fabbed your intake? Who did the exhaust?

Britain Smith
Marty did the intake, exhaust, breather box, intercoolers, injector bungs, turbo selection, blow-off valve, wastegate, and some of the AN-line plumbing. That guy does it all and a great resource for everything!

Britain/ Marty good looking stuff wink.gif I don't think that you'll have any problems with expansion/ contraction of the engine versus plumbing...you could always put a short piece of flex-bellow ahead of the turbine inlet (L - R sides of header) and then do a "Bump Hose" on the intake tract. We never have any problems with a non-flexed turbo header---most of the breakage occurs when the driver ass-ends his car into the armco at speed sad.gif

I like the idea of your lightweight / big HP powerplant.

That set-up with the single turbo hanging off the rear is timeless...I love it.

Everyone has there own opinions one way or another on how the motor should be built, or how I should have done it differently, or what I shouldn't have done. I agree with you (as does Marty Staggs) that there shouldn't be any issues with expansion/contraction of the motor with respect to the plumbing. If there is then I will go about adding a flexible bellow inline. Building a turbo car is a very fun project and can get out of control very fast ($$ that is). I am getting closer every day and should get it together soon. Custom parts are needed around every corner and it all takes time.

Who needs a muffler when you got a turbo? I will be a bit loud, lol!

Don't you mean "a bit LOUD"

Yeah I guess the turbo will help a bit. And you will still likely be quieter than the average fart-can equipped Honda.

Before you leave the turbo shop, have a small muffler built-that you can attach for normal street driving. I use 4" od tube with a shrort section of 2.5" ID resonator core (no packing) and 2 end caps. This takes a big bite out of the "Snarl" but does not effect the spool up of the turbine (backpressure). This will keep the law off your tail, and keep under 96 Dbs for the track. Nobody needs fixit tickets flipa.gif
