hi new to forum looking for advice on what way rotary should be put be built plan to use in rally car something different does any body know how the old group b rx7 engines were done or is it now best to start with rx8 engine i will wait now and see what u experts have to say many thanks. p s no turbos.
Oh, sounds interesting :) Look forward to seeing what people suggest.
The minimum you would need would be a 13b bridgeport engine.
A Peripheral port would be better,but both would work very well.
On the Group B rally RX7\'s of the late seventies and early eighties they ran with Weber IDA carbs that were bored out to 51mm.

what is needed along with pp houseing ? or is standard parts ok.
Lightened and balanced and race clearanced rotors,carbon apex seals or ceramic if you can afford them,competition stationary gears and bearings,higher pressure oil pump regulator,baffle plate in sump or dry sump,tuned length exhaust,holly redtop fuel pump,IDA weber carb and manifold.
These are mainly what are needed,but there are some other things too.
Regards
Carl
dont forget a large budget.
:guinness cheers folks it just confirms how little i know about them so what sort of money are we talking about to build pp type engine also what about rx8 engine its already powerful as it is . also does any body in ireland work at rotary engines.
hi again does any body still rally a rx7? in uk
I have a feeling the rules about rallying rotaries in the UK got a little silly :( However the person you need to speak to on here is MikeLMR, he knows a lot about it :yes
Eddy Doyle is in Ireland and builds engines.

A set of 6 ceramic seals will cost about a grand:http://www.pineappleracing.com/index.asp?PageAction=VIEWPROD&ProdID=23
PP housings aren\'t cheap, and neither are lightened and balanced rotors with cutom E-shafts
