It might be a stupid question to some(or most), but I\'m asking it anyways.
We\'re starting our FC build soon, and we\'re not experienced with rotary engines, or the FC chassis.

What we have:
-\'89 LHD FC3S S4 NA chassis, complete, but stripped down, engine had low compression when we took the car apart
-\'91 RHD FC3S S5 TII, everything but the chassis itself.

What we want:
-Rebuild/build the engine ourselves, or at least most of it so we can learn how it\'s done
-Carb setup for simplicity(if we can get 200-250bhp out of it, it would be great.
-reliability
-balanced suspension-setup

So can anyone help us out with some basic tips?
The most important part is basically the engine, which engine to use to start with, how can we make it reliable enough to keep it running for hopefully a few years or so.

then the ugly question.. will it ever be reliable enough to compete with piston-engine reliability?

The first thing I would do is decide exactly what you want out of the car. You can get 200-250bhp out of the NA but it is much easier and cheaper to get it out of the Turbo engine.
Reliability wise I can\'t see it being anyworse than a competion piston engine as long as you look after it. There are plenty of people running rotarys in competitve action.
Keep posting updates as you build the car too as we all like to look at pictures!

I don\'t need to upgrade my stock turbo to beat your ass!

Right now my mate and me both drive a Suzuki Swift gti, mine has a turbo, his hasnt.
I\'M constantly fixing stuff and improving stuff.. and he never does anything, his car runs brilliantly, while mine constantly needs fine tuning, remapping, cooling issues. And we both have the same amount of fun.

Thats why we settle for less power and go with NA, just to drive as often as possible, without issues.
We\'re going for carbs, and maybe get some porting templates for a streetport for some extra power, and do it with the power we have..

Bridgeport the engine and run high compression rotors.
Or for a bit more power Peripheral port the engine.
Both engines will make 250hp plus.
The carb to use is a modded IDA weber downdraught.
Bore out to 51mm chokes.
We warranty our rebuilt engines for Detonation, track day\'s and RWYB and NOW for 30 months which is two and half years or 30,000 miles
We also build all types of race or road engines.
We build race and track cars too.
Any kind of porting undertaken.
Single turbo conversions.

Thanks for the info!

Will we be able to drive to the track and back with PP or bridgeport?
Are the racing beat intake manifolds/carbs any good? We were looking at them earlier.

I\'ll be a little more specific about our doubts btw

What should we do with lubrication? Just premix? Or do you need to feed oil in the engine itself(apart from your usual oil of course)
Dtss eliminators nessescary?
Should we use the S4 n/a engine or the S5 T2 engine as base or use a little of both??
Wich seals should we use?

Do you need any of the engine loom if you\'re using the carbs/NA dizzy
What parts of your vacuum system can go and what do you really need for it to work.

Sorry for asking so much questions, but we need a little head start on this, and maybe someday wel\'ll figure things out ourselves ;)
