I'm worried about fitment of the bonnet (which I don't have built yet) over the manifold as well. It seems I can't offset to the left (driver) side without causing issues wth the steering. Anyone else with a 1.6/Haynes combo run into that?

Thanks for the input guys!

Your right about the bonnet fitment. I stuffed my engine as far back as i could because thats where the gear shift ended up in a nice spot. Also it will center the weight better for you. I never knew why Lotus and Caterham set the engine right on the front wheels?. By bringing it back and down it may clear. Yo car is a bit smaller than mine. I have 2 extra inches I don't think you have. I was able to lower the engine enough to make the bonnet clear by 3/4". also by doing that the crankshaft ended up exactly centerline with my spindle centers. Weird but it did. Actually really cool for center of gravity.

Car is looking sweet Randy keep it up.

Also on pedals...

Has anyone used the stock Miata gas pedal and shortened it? It looks like you could just mount it using the existing two mount holes if you trimmed off the clutch pedal bracketry. It would definitely be too long though, so you would have to cut and reweld the pedal rod to shorten it up a bit. See the stock below:

Then I could use floor mount pedals as in the post above, but use the stock Miata pedal for gas. Really curious on how this set up feels if anyone has used it. I could always build it and modify it later if it doesn't work out...

Believe it or not its easier to build your own and use Wilwood masters. Their only $50 each. floor most all of it

I like having nuts welded in for "blind" areas as well. After doing a number of regular nuts and finding the threads often need to be cleaned up with a tap afterwords, I discovered weld-in nuts. They come in a huge variety of shapes and types. You usually drill a slightly larger hole so the nut sits down in it (it's still flush on the outside) and they have little stand-offs that let the weld penetrate under the head for better attachment strength. They take less weld filler (so less heat and distortion) and there's rarely any thread clean up.

Just do a Google Images search on "weld in nuts" and you'll see what I mean.

Cheers,

Don’t rule out rivnuts. I’ve used about 50 of them in the last couple weeks. So much easier with great holding power. Just need to keep in mind how much you need to hold.

Great tip on the weldable nuts. I can never get rivnuts to work (though I've only tried a couple times)! I should probably watch a tutorial...

I had to work this weekend, but I spent the morning building the gas pedal. I chopped it off the brake pedal mount, then chopped the pedal down. It looks like it'll work. I'm going to keep playing. I think I will end up building a clutch pedal using the stock master cylinder, but I'm leaning toward a Southwest Speed brake pedal/MC set up (looks like a Wilwood) after looking at JAF's build set up and taking advice offered.

Here's the work on the gas pedal so far:

Thanks - how does that work out with the brake pedal placement? The Miata pedal is angled (as you can see in the photos below) with the bottom aimed toward the brake - I worry about interference with the pedal. It may work out great for heel/toe though, so I'll have to fab everything up and see I guess...

I tried to Locost the pedal box and perhaps over did it. Clutch pedal and mount are modified from the Miata with a Wilwood MC. Brake pedal is from a Spitfire and the mount is custom built to make for the error of my earlier attempt. Brake master is from the Miata along with it's proportioning valve. Throttle is a Speedway Motors unit.

My attempt to skimp on the pedal box wound up costing about twice what a decent (and much easier to install) unit would have.

Thanks for the input and links. After consulting a few different folks with outstanding experience, including this lot, I've decided to abandon the "low cost" approach to fabbing up my own pedals (though that does disappoint me a bit). Seeing the GBP to USD drop again, I opened my search to more than Pegasus and Summit, and found a pretty good deal on a pedal assembly.

I got some feedback on the different set ups and balanced price and product. I ended up getting the OBP set up shown below. It gets here May 4, so hopefully I'll be able to sort that bit soon. I'm pretty chuffed about the pedals though (I should be for the $$ commitment!). I bought it from Rallynuts in the UK. Cheaper even with shipping than anywhere I found in the US.

It comes with the remote mount reservoirs and master cylinders. I spec'ed 3/4" for the front brakes, 7/8" for the rear brakes and 5/8" for the clutch.

If your going to use the stock Miata slave on the clutch your master is a 3/4”. Also when you set up the throw on the clutch mine ended up to be about 1-1/4” for the clutch to disengage.

3/4"? I referenced Keith Tanner's blog as well as info from Dave Struve and JAF, and all three showed 5/8". It is a 1.6 if that matters...

Thanks for the set up info though! I already have the unit on the way with the 5/8" at this point, so I'll have to see if it works for me.

I saw that. You would have more pressure less volume if I am thinking correctly. I found some stock Miata info when I was ordering my masters. I think they all use the same slave.

Gotcha. I think you are right with pressure and volume. I know back in the 914 days we used to "upgrade" the 914-4s to the 19mm master from the same vintage 911 (stock was 17mm). That gave a better pedal, but wasn't a huge difference. I'm thinking both 3/4 and 5/8 will probably work for the clutch as well...
