Type 1 in a 914?

tottestad · 02-14-2011, 11:45 PM

Has anyone put a type one in a 914? If so I am looking for advise on keeping it cool. I have the stock doghouse shroud and an external oil cooler with fan. I must also mention that it is a 2110cc fuel injected turbo motor. Any ideas for effective intercooler placement? I will post pictures soon.

Thank you all for your future advise.

Not sure how many have done the swap. I'd measure first to make sure it fits.. as you might need to do some additional motor mount fabrication and making room for the turbo. I believe one reason the type IV was used was due to its overall "flater" size.

Here is what Ive got so far. Again thanks for any input

I'm not aware of anyone who has succeeded. The exhaust in the Type I is very different and points the wrong way. The mounting is also very different. Not to mention the cooling. The Type Is also tend to be more peaky (less torquey), more highly-stressed, and more fragile than the Type IVs. The Type I swap is usually looked on as a downgrade for the 914, not an upgrade.

As for 914s with intercoolers, I've seen them in the engine bay, and in the rear trunk. Ducting was needed in both cases.

I hadn't thought about the trunk. As for mounting, the case is an aluminum bubble top universal, so it has the tapped holes in the front. I simply alas up a bracket to the type4 front mount tabs. The exhaust I had cut and reweld, due to the motor mount crossbar being in the way. It runs great and the head temp is about 260-280 on the freeway, but as soon as I exit, the temp starts to rise. And my intake temp is consistantly 125-145.

Thank you for your time.

I don't see any engine tin???

Wow, cool--now I know of a 914/Type I swap!

A cooler won't really help with the head temps. You might consider a different cooling setup, but I'm not sure what would work well. Perhaps just some ducting of cool air from outside the engine bay to the fan inlet? It's definitely not great to have head temps going way up around town.

Yeah. I'm having a hard time completely isolating the heat from the cooling fan. Are 280 deg head temps okay?

How about this one... I know you are jealous!

tottestad · 02-17-2011, 07:51 AM

What is the blower fan and ducting for? I assume heater?

tottestad · 02-17-2011, 07:52 AM

With that setup dont you lose the mid engine weight distribution?

Dave at Pelican Parts · Dave at Pelican Parts's Garage

Yes, it is.

Yes, you do.

I'm pretty sure the "you are jealous" was sarcasm/humor.

I don't know what sorts of head temps are expected; you might talk to some Type I guys about that.

Yes it was! For the record, that is not my car! Just a pic I found on the web.

Disclaimer- I have never owned a turbo/supercharged car, and only driven very few.

I would think you want the intercooler to be a short run, less pipe to compress the air in has to be better. I have seen cars that have a duct on the side, a la MR 2 or Boxster, which would maybe be good, might be better on drivers side of car, away from battery. Might be okay right below engine lid. You can also make the solid metal part behind the rear window into a screen, like the hood, to try and augment cooling, could even mount your intercooler there and have a really short straight run into the intake, right in the middle.

Do they ever blow up? Intercoolers I mean, because that would be right behind your melon.

I'm building a Turbo Rotary for mine. I'm using a water to air intercooler. Much more efficiant than air to air and perfect for a mid or rear engine car. Air to Water Intercooler has a bunch to choose from.
My build is here...

I really like the water to air intercooler idea. Nice! Thanks. I have never seen an intercooler blow up, but anything is possible. I ran this motor at 16psi of boost in my old 68 bug, with megasquirt ms3, and it is an animal.

How structural is the inner sheet metal on the passenger side of the engine bay, generaly where its rusted out from the battery?

Dave at Pelican Parts · Dave at Pelican Parts's Garage

That part isn't that structural. What's below it is immensely so--the suspension console for the inboard end of the right-rear wheel. It's not uncommon for 914s to suddenly develop a ton of negative camber on the right-rear, and that is because the console was weakened enough to break off the chassis. Not so good for handling to have one wheel flopping around...

Also, the water/acid mixture from the battery tends to migrate forward along the angled metal under the battery tray into the "hell hole". Since the corner of this is on top of one of the two the main longitudinal members of the chassis, it results in significant flex and possibly chassis failure. Not to mention that the longitudinal in that area has a hole in the bottom of it for the heater tube to come out, so it that is a weak spot already.

So that one part isn't too structural, but where the rot goes immediately afterward is absolutely crucial. And is a real pain to repair and keep the chassis straight.

I already repaired the frame rail, or longitudinal, but stol have a hole in the sheet metal I'm using to direct air over my intercooler. Just wanted to make sure I wasn't missing something. Thanks dave.

I didn't see it mentioned, but there is a good discussion in the turbo forum on water/methanol injection, especially as it relates to the 76-77 930 which has no intercooler. Water/meth can be run in tandem with your intercooler solution and will help with your head temps while on boost. Look up the user cole930, he's stared some very informative and recent threads on the subject.

There's another guy on here that goes by the name iamchappy with a turbo 6 in his 914. He has threads on the build specifically his intercooler routing. He mounted in the rear trunk and use a fan as well as a modified spoiler on the end of the lid to direct air through the intercooler.
