Nice pics there matey....do you happen to have any pics of under the engine bay, how the engine and gearbox are both mounted. As for the turbo manifold, does Dyson have a turbo manifold like yours on the shelf , as a 20B in a 1st gen configuration ?

Yo Andrew, is this Craig from Dyson's place ? One more quick question, was the engine mounted from the front cover with custom brackets , or from custom side mounts?
Thanks
Rana

Yes Craig Dyson. Dyson Rotary have a very good reputation over here. My engine was front mounted, using both stock and custom cross members.
Turbo is a T04 rear with a TA45 front, 72mm front, 1.32 rear.

I took it down to Craig and he had it sorted in 30 min.
I'm using a Microtech MTX12 which has been upgraded to a LTX12.
Dyson Rotary hold the record in Australia for fastest untubbed rotary. and I think they still hold the record for fastest untubbed 12AT, with a best time of 8.76@153mph

Thats lovely
Looks like a job well done- about how much all up has the conversion cost? maybe something ill consider in the future, although i have a new 13bep on the way, and that is likely to last my lifetime ! hmm
Good job! More videos please :P it sounds great

Around 25k for the conversion so far.
$15 for original conversion with rebuilt engine.
$5500 for Dyson rebuilt engine after original engine spun a bearing.
$5500 for turbo, intercooler, piping, exhausr manifold, wastegate, 1600cc injectors etc
Worth every cent

Andrew, Thanks for taking the time to post the pics up , I really appreciate it. The jobs looks quite immaculate, neat indeed. I wish I could get my hands on a turbo manifold easily as you have. THat would make things a whole lot easier to do mine....My car is presently at the auto electrician installing a Haltech E11v2. I presently have a 13B in there, but have plans of going 20B but not sure if it will be in the 1st gen or a HB Cosmo instead...but it sure looks good inside here !!
