...Allo.

What's the cost/feasability of DIY-rebuilding a 13B and bridge-porting it?

Anyone else who knows, please let yourself be known!

Drex did the rebuild on his himself iirc, documented it somewhere, but i think he sent it off to be ported (might be making the last bit up?)
 
I've seen an Aussie (if I recall correctly) site before that has templates for DIY-porting...

Mark out stencil, get out your drill and dremel...

I take it you've got access to an engine that needs a rebuild and it's going cheap? or an entire car going cheap?
 
I did mine for ~£1300, but that included a new end plate, and having the porting done professionally. I also needed a new bearing. All that added about £500 on to the rebuild.

If all the housings, plates, rotors and bearings are in good condition you could probably DIY it for £700 ish, maybe a bit less.

As for DIY porting, here are my findings when I was researching (I was going to give it a go myself):

Yes it's possible with a dremel and a template, but the actual port face (and that's all a template is good for) is only a small part of the porting job. The shape of the internal chamber of the port is very important, and that only comes with experience from what I can gather. Also, matching the ports is important too. In the end I just paid the extra to have a pro job done (I took the plates and housings to RX Motors).

Best bet would be to pick up some scrap plates/housings from someone like RX Motors and practise on them. I still have my old plate lying in the garage, I keep meaning to attack it with a dremel.

Pensk I'd recommend you mail Mickey D as he has fairly extensive knowledge and experience with a rotary motor.
