HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

GM 60* V6 swap

Post  RacerX on Thu May 08, 2014 9:23 am

Just wondering if anybody has done a 60* GM V6 swap? My thought is it has to be cheaper then the
V8. It's a little more HP but not enough that you would need a big brake kit and the transaxle would be able to handle the extra HP. So, has anybody done this swap yet??

I hear what your saying, BUT, with that big V8 comes more power and torque. I'll need to add a big brake kit, bigger wheels and tires, and a transaxle from a 944 turbo. If I can drop in a small V6, like the 3.4 60* GM motor, that only makes about 20-40 HP more than the stock 944, I'll be able to forgo all of the above mentioned up-grades. I'm not looking for max power, just a little more power than stock. And the 2 biggest reasons for doing this would be cost and reliability.

Well the 60 degree is a pretty good engine, nice compact size, and easy access to parts. The biggest question is will the brake booster still fit with the engine in there? If so then I would think its an inexpensive upgrade. I ran an LS1 in my 924 with 255's out the back originally and it worked; of course I upgraded the brakes to 944 NA brakes at the time, but had a lack of a brake booster: So it is possible, just not ideal.

What kind of car do you have? Is it a daily driver? Track car?

Daily. It has been redone of course and is going through a brake upgrade as we speak, so your point of keeping cost low is valid. You can get a very modest 300 hp 5.3 liter in your car for the same amount of money as the 60 degree and have a greater potential for future upgrades. That being said, the 5.3 that I talk about is slightly heavier then your RWD 60 degree iron block aluminum head configuration. This is my conversion:

This one would be a track toy as I already have a dedicated 944 race car.  The race car uses the stock Porsche motor.  I want something with more reliability, engine wise, and a little more power.  If it was cheap to add power and rebuild the stock motor, I'd stick to it.  But it's not.

Although not as inexpensive as the 3.4 liter, this has FAR more potential! The reason why the 3.4 liter 60* is so popular for the British cars is the limited size of the engine bay Smile

GM 3.4 V6

Post  simon123 on Sat May 10, 2014 8:26 am

I have two modified cars, a MGB GT with a crate 3.4 GM V6 and a 944 with LS1.
My MGB has headers, and a Holly 390 and I believe produces about 200 hp.

I would only put this engine in a 944 if I was looking to replace a blown/worn out engine, the end result would be a nice economical daily driver. For real performance I would use the LS1.
