Picked up a couple carb manifolds as seen at the beginning of the post -

A Nisaan Motorsports produced by Ed Pink manifold popped up so I snagged that...



Then popped up a cast manifold that I was interested in so I snagged that too. It should be here on Monday for more photos.

As it sits right now


Lots of parts....

Hoping to get the block off to the machine shop in the next week or two and really get the process rolling

I love when FedEx Shows up at work!



Second Manifold showed up. Pretty stoked on this one. Will almost definitely be running this one. Now I just wish I could find out more about it... cant find any info of it, and I have only found one photo of it mounted up on a car. Is anyone familiar with the EWL or A.D.M.L. casting marks? Looks like there is a part number following the EWL of 671-2. Someone put some serious thought and investment into the mold for this one, so hard to believe there aren't others out there.

Anyway more photos

The cast one looks really nice. I was a little surprised at the quality of the fabricated Ed Pink manifold. I'm looking forward to your build. It's always cool to see how another person goes about doing things!

Thanks duke- yea I was a bit bummed on that one... but the cast one I'm excited for.

Anybody have a good reccomendations for a rebuild kit? The machine shop I spoke with is looking for 1300 for "stock" parts...

Looking at Cleggs or RPM Machine right now - any experience?


Also ordered the T3 trans mount, oddesy battery mount and picked up a full ford edis 4 set up off Ebay.

Got a few more updates... mostly just parts I've picked up.

Scored most of a motor along with a ton of really good performance parts on craiglist for super cheap, so looks like I will be building a forged motor-

Here is the first part. Block appears to be bored/honed already. Most of this stuff wont get used, but it was a take all deal so I got em all. If anyone needs KA parts let me know!



Block - I will likely use this one since it may not need to be bored. Need to get it measured to confirm.



Now for the good stuff! Brand new still in packaging - Wiseco 9:1 pistons, Eagle Rods, ARP main and head studs, King Bearings and a Commetic head gasket - Also an AEM Fuel Rail and DeatschWerks injectors, dont need either one of these so they will both go up for sale.


The big question now is do I run these 9:1 pistons or sell them and get 10.5:1 pistons...

With a Decked head and block and a thin gasket the 9:1 will bump up a hair more and be pretty close to the stock 9.5:1...

Or I run 10.5:1 pistons with a thicker gasket to bring the compression down a bit and run on Pump gas better. Everything I have ready basicly says over 10:1 you need race gas or at a minimum 93... which we dont have here in Cali.

Oh yea... time line on the KA has been bumped up to ASAP.

Got the L back together and went to fire it... it doesnt sound pretty.



There is no reason for me to pull it and work on it before the KA, so it is just going to wait. Once I have the KA ready Ill pull it, install the KA, and then tear down the L to see what the issue is before selling it or parting it.

Also picked up an AFCO radiator for the swap. Although unfortunately my nismo radiator cap wont fit...

New AFCO rad on the right, and Koyo 510 rad on the left for comparison.



Picked up a linkage rod for the carb manifold, but will need to drill and tap the mount holes since the rod towers are bigger then the mounts on the manifold.

Still need to figure out the trigger wheel. If anyone with a KA could snap a picture of the clearance between the pulley and the timing cover that would be great. Didnt do that before I tore the motor down.

1/4" maybe at the top.

Thanks! Those were exactly the pictures I needed... And didn't want to see...

I have found a few bolt on wheels that I thought I might be able to sneak between the pulley and the timing cover... But that's not going to work. Largely because of that nub on the timing cover next to the pointer.

I guess I'm going to have to do some machining ....

Hi there, I'm new to this forum and I was just browsing your thread and thought I would offer a couple suggestion as I have built quite a few engines with crank fired ignition or full engine management (mostly using SDS and Electromotive). But I wanted to make sure understand the problem correctly.

I'm assuming you are looking to use an electromotive type trigger wheel? Have you made the final call on this?
Is the interference with casting on the timing cover and the diameter of the trigger wheel? if so, is it with the timing pointer or the actually casting above it on the timing cover?

Or, is the interference due to the distance between the pulley and the timing cover (i.e. there is only 1/4 inch between the pulley and the timing cover and the trigger wheel is also a 1/4 inch thick so it won't work)?

EDIS/ MegaJolt requires a 36-1 trigger wheel that is 1/4" or thicker.

The clearance issue is between the both the pull and the cover between the 2 and between the pulley and the cover in the diameter sense.

There are a few different bolt on trigger wheels I was hoping I might be able to tweak and run... but I guess I'll have to go the route of Duke and others and have the inner most pulley turned down and a trigger wheel turned down to match.

IMHO, i would mount it to the front of the pulley. I can personally vouch for doing this on SR's KA's and L28's without issue. You may just need to machine the centre of the trigger wheel to ensure crank bolt access is good. I would actually just look at having a machine shop weld it right onto the pulley.

Here are a couple pics i found or this done on SR20's with dry sump, but the theory applies and i'm sure you get the idea ( i really like the way these guys on fresh alloy did it)- THE LINK is a Different build then the pics so check out both ;)

the thing is a wheel on the front on the KA needs to be pretty big.

i like how clean having the wheel in the back is. Also it means a shorter mount for the sensor so less vibration there.

The BHJ miata damper is killer
