I didn’t want to highjack the engine sale thread, but I am borrowing one of the pics.

I have ‘88 3.2 engine for my conversion, but it didn’t come with duct and fan as shown in the pic below. I’ve been considering buying the setup, but now I wonder if it will fit under the engine lid.

Can anyone tell me if it will fit, or if there is a better fan setup to use for the heat exchangers?

Thanks for any help.

It doesn’t fit ( at least well). I would “backdate” your heat. Then you just use the engine fan to move the hot air from the heat exchangers. It’s common to do in the 911 world, is very effective, cleans up the engine bay and even saves some weight from not using the blower fan.

Ditto.

That’s a nice feature of the 3.2. The early side heat pieces bolt right onto the fan enclosure for use with 914-6 or after market (mb911) heat exchangers.

I even backdated the heat on my stock 1.7 car and it worked great. Tons of heat in a small cabin area.

thanks for the pic and the link. It does look better this way.

Thanks, I was curious if this would work: seems like it does and is the best path.

Thanks, and I do have Ben’s HE’s. Glad I asked before buying parts

I did it. Used the 3.2 motor and if I remember correctly all I did was shave the lip down....this allowed it to clear the engine lid.

I also got it to work with the stock blower, but its a lot cleaner to use early parts. A 911 engine in a 914 does not need an extra fan.
Here are some pictures from my blog

I try to learn something every day...This is a good one. I've been stressing where that darn blower was, and how I could hide it in the engine compartment. Thanks

There's a couple threads on pelican about backdating heat.

Yeah, it’s great everyone here is willing to share their experience and knowledge. I for one, have benefitted; hope I can help others as well.

I was a little worried when I cut the old fan mount off - looks like it’s OK, I’m going with the backdate

Thanks, I’ll search them out.
