I think that would held disperse the load from the engine to the mount. Do you plan on shifting the engine back at all?

Jeff20B

Maybe only an inch. We still want access to the oil filter and don't want to have to dimple much for the slave cylinder and clutch fork. It's going into a GSL-SE.



I'm thinking fairly conservative peripheral ports and stock apex seals should keep the HP peak before 8k-8400 so we don't over rev it and blow them. We'd also like it to be fun to drive/streetable. He already has a couple race cars.



Heh, a GSL-SE is getting 12A rotors.



Well, 4 of them.

Schweed! I want to see this thing. Where've you been Jeff I havent seen you since the BBQ last year.

Danomite

Why are basing the engine on a 12A? Is it just to keep it as short as possible?

Jeff20B

Yes and because he has several '83-'85 12A cores to go through. The total length will be 630mm or about 25" from the rear plate to the front cover. It will interfere with the front sway bar so we've got to move the tranny back a little. We'll also rotate the crossmember so we'll have enough room for an oil pan. The dual GSL-SE intermediate plates should solve any motor mount strength issues we would have had with only one intermediate.



Thanks to Banzai, it looks like I can get away with an FC front plate to take advantage of the larger turbo oil pump, which Jeff Bruce says will be enough for a street driven car. The next step is finding someone to do the p-ports in some rotor housings.



A GSL-SE front cover with OMP will allow for four oil lines; one to each rotor housing or carb in a dual IDA setup, depending on whether we need to get four new rotor housings, and if they have holes for oil injectors, and if not, directly plumbed to the carbs or manifolds should work.



Would a fuel cell and larger lines be a good idea for the kind of output this thing should produce?

Danomite

Depends on what size the existing line is and what hp you want to be able to support. I dont see any real reason to make a new cell, assuming you can fit the pump in the stock unit.

Jeff20B

Stock line size is 5/16, HP expected is 400. If I recall correctly, the SE had an external pump. It would be no problem to plumb in a high volume low pressure pump in the stock location. I was thinking at least the line size should be increased to 3/8" or so, especially at such a low fuel pressure.



The owner of the car wants to do a widebody and suspension upgrades, so I don't suppose he is beyond a fuel cell at this point. I'll run it by him.

Danomite

Most of the aftermarket 400+ pumps run a 3/8 line. The pump should be mounted in the tank to help keep it cool. Is there an access panel in the stock cell?

Jeff20B

There is a round hole at the top of a fuel cell, but it's for filling. The stock tanks of 1st gens just have lines and external pumps. I'm almost 100% sure the GSL-SE has an external pump. I think a large Carter or similar carb pump would work ok, but it would be a good idea to have a 3/8" feed line, and it might be more cost effective to replace the stock tank with an aftermarket fuel cell rather than figuring out a bigger sumped suction tube in the stock tank.

R.P.M.

The GSL-SE's do have an external fuel pump.



That SE sounds like my old GSL-SE.....except I only had 1 12A in it LOL
