New 2.8 Liter Six for the Racecar, I'll be asking a bunch of Conversion Questions Options

[motorvated]

The first question I have is related to modifications to the engine shelf pieces required for the 6-cylinder conversion. I noticed the Patrick Motorsports sells an expensive engine shelf kit for the 6-cylinder conversion. But, since the 6-cylinder is going into a Racecar, can I just cut out the entire engine shelf to maximize the available space in the engine compartment? Or, has anyone made a template that can be used to modify the 4-cylinder engine shelf to accommodate the 911 engines? I'd like just to remove the shelf parts if they are not needed. Thoughts on this? How do you other racers handle this. Many more questions to follow. I know there are many conversion threads out there, but it's hard to weed through them to see if they address the question(s) that I have. Plus most of Tigre are for street car conversions, not race cars.

I’m not running any engine shelf or tin either.


Did you get conversion parts with the motor?

Drivetrain came out of another 914, but the only conversion part that came with it is the engine half of the front engine mount. So I will need engine oil tank, external oil cooler (?), transaxle pump and cooler, headers, etc. I also need a dual plug distributor. So if anyone out there has anything on a shelf in their garage and wants to sell it, please let me know.

Not great, but here are some pics of my engine compartment. My engine has a 911 style (FAT Perf.) fan shroud so it's similar to your 6 cyl fit, but more space between fan and firewall. I do have a dry sump with the oil tank taking up some of the drivers side engine compartment. 6 installs typically put the tank up in the front trunk. My car has 2 coolers in front with lines back to the tank. I'll take pics of that soon too.

Rear trunk area cut out for access to trans, cv's etc


The original "shelf" with the channel for weatherstripping is mostly intact, but cut away where air ducting from the front was channeled back to the engine. With the 911 type shroud and no engine "side tins" it leaves quite a bit of gap between engine and firewall / engine compartment


Oil tank is on the drivers side against the firewall. As said. with a 6 there's probably not room back here so most people put the tank in the front. Mine is a 4 so it has a 1.5 gal tank. You'll want a bigger one for as 6.


I'm overdue to put together a photo thread on this car. It's pretty well built. I'll try to get to that soon - ish....
