Me and my buddy recently picked up an 86 GSL with a blown rotor and excelent body and have been toying around with different engine ideas. Well this weekend we picked up a steal of an engine setup in SC. As per the seller listing this is what we got:

13B J-Bridge port (4port). 12a sidehousing with GLSE rotor housings. Rotors from a '91 (lightest ones). Carbon apex seals courtesy Mazdatrix. Setup for a carburetor, includes the intake manifold needed for a Holley Carburetor (4 barrel FTW). Less than 2k miles on it.



Also managed to get a trans with a reinforced gear set, solid motor mounts, header, and racing beat filter.



Right now we are in the process of moving the car to our friends garage to start pulling everything out. Now we don't have the carb which is where my questions begin. I have been looking at holley carbs and have narrowed it down to the fact that i am going to need a 600-650cfm one but what i cant find is if any holley will fit on this system or is there a specific holley made for the rotary setup?

second question (gonna be posting these up as i think of them) As far as the ignition system goes i am thinking msd would most likly be the best solution. What suggestions should i use as far as rotary specific ignition systems since it is obviously going to need to be able to handle the leading and trailing spark duties



Edit: not that it makes too much difference but the chassis is a GXL not GSL

I would go with the 650 DP on that J-bridge.



Some people run the stock ECU to run the ignition. I ran a distributor and ran the FC leading coil off the leading ignitor. Trailing run through the cap and rotor.



Search "DLIDIS" on this forum, its another good option.

thanks for the heads up. as far as a 650 dp goes i can use any holley i assume? they all have the same bolt pattern is what i am guessing.



Also i did a quick search for DLIDIS and i am not coming up with any results

Any 4150/4160 style carb.







Sorry, it was "dlidfis". 1st generation FAQ section.

so something like THIS

wouldn't work?

Bump for any more input

ok i surfed on over to the 1st gen forums and found out about the dlidfis and sounds like the way i want to go with the ignition system...however every write i find on doing this setup is based off the 1st gen setup not the 2nd gen. So my question is if there is a 2nd gen specific right up for this. Can i use both trailing and primary stock coils? and what wiring if any am i going to need to scavenge from a 1stgen

bump, interested



you said the rotors were 91 and the housing was gsl-se, with 12a side plates? is that possible?

to tell you the truth i am not sure if it is possible but the engine is all in one piece and it has 13B irons. i havent taken a really close look at it all since we just loaded it in the car pretty quick.
