My new project Rotary Drag Car

[MikeLMR]

I didn\'t think the B2000 rear end looked much different from the standard S3 rear end ? having said that I have only seen photos of a B2000 rear end ( on the lookout for a pickup to use as a daily beater/ lugging parts about)

The Mazda vans also have strong boxes, seem to recall my Dad saying that a fix for early FC\'s with knackered syncro\'s was to have the panel van double syncro\'s fitted to replace them

As you mention street porting your motor yourself,  you should check out NoPistons.com.

There are lots of threads about porting engines on there. Any post that Judge Ito makes is usually worth reading as he seems to be a very good engine builder and he also sells porting templates.

I\'m very tempted to try porting my engine at somepoint in the future.....

I streetported my primary and secondary ports on my FD with excellent results, with the first gen i wont mind if its heavy on fuel or has a lumpy idle, neither of which i have on my FD.

Go for it.

Keep meaning to do something with the 2 first gens festering n the drive, but other projects/kids/work/gardening always gets in the way.

( I like 1st gens the best)

this sounds like a great project. I have seen people using b2200 diffs in rx3\'s in oz for a drag racing car. The standard ratios are great for the rotary on a quater mile.Some are like 4.8 to 1.
 I am going to use a hilux diff as I think it is a 4.4.  Also b2000 and b2200 axels are quite alot thicker than standard rx7 ones. The might also be 4 pinion as well.
  Being able to launch at top end rpm and know that your driveline will stay together is a great piece of mind. Please keep us informed as to the progress of this.
 cheers.
