Drive train

Most likely candidate at the moment:

Modified BMC 1275 engine + Datsun 210 transmission

$550 Posting and link to site

Engine

Suzuki G10 or G13 + Samurai 5 speed 3 cyl vs 4 cyl = 15#

Ford Duratec

Cosworth

http://www.raceline.co.uk/

Ford Racing is supposed to start selling crate engines in 2012. Transmission would be either the T9 (rare) or the T5. I think I could get a new T5.

Source for T9: http://www.quantumechanics.com/categories.php?op=newindex&catid=17#

Comparison of several engine sizes http://www.lotus-europa.com/europa24fps/ebeyer.html

Tires and wheels

Want to get rid of wire wheels, which means I need to replace the front hubs and rear axle shafts and diff housing.

Stock: 4 x 4" x 13" (100mm) bolt pattern

I want something very conservative / traditional racing look like Panasport / Minilite style with 165-70 13" tires. but there are very few 13" tires out there.

Thinking about going to a P165SR14 like this one from Michelin

Section width 6.7 on 5" rim Diameter 22.4"

With this VTO wheel: 14 x 5.5 size

or this one http://www.northwestimportparts.com/MGB-Mini-lite-style-wheels-d709.aspx

Check 10.10 tires for tires. They have a great size calculator. 165/70 13" or 165/65 14" look good.

Winner's Circle has excellent rear end upgrades

Final drive ratio: stock 4.22, replace with 3.55

Early RX7 has a 4 x 4 1/2 bolt pattern, same as MGB. So can I put MGB parts on the front end and use 4 x 4 1/2 wheels all around?

Electrical system

Battery - Miata style AGM or Optima

Alternator conversions

I have a generator currently.

This is the $130 option I plan on using: http://www.mgccars.com/electrical-upgrades-for-you.html It uses the Delco Remy cs130, aka the "Saturn alternator".
