202bhp as standard with all the restrictive ford stuff on it.
So a 2.5 l engine is less than 2.0 l then?
I made that mistake too. 
No, i'm, just ignoring that restriction as it seems the limiting factor on a budget.

231 version of the RX8. Tiny motor and the 6-speed gearbox will fit most 7's.
You can normally haggle breakers down to the £1500-£2000 mark for engine, box and ancillaries.
Only problem is the Oil Metering Pump. The Mazda ECU controls it, but you will have to junk the Mazda ECU to get the engine to run outside of its
normal application.
When I last looked (about 18 months ago), there were no aftermarket ECU's that could support a rising-rate OMP.
There were a few plane-engine builders using the RX8 and they had made OMP's, but I never fully explored that option.
The other solution is to just pre-mix your fuel with some oil... bit of a PITA though!

To me the obvious choice is the Honda K20A which is 197BHP in production format. Easy gains just from induction and exhaust mods. Probably the most
reliable of all the engines mentioned so far surely?
Cost depends on how much you will be fabricating and how good you are with modern wiring/electronics I suppose.

That's fine as long as the scrutineers take the same attitude
I think the Duratec is the obvious choice if you aren't keen on the 20XE. The S2000 engine is ok, but fetch a very large premium and are
physically large engines.

Can't believe nobody has asked you what your budget is yet. The answer to this question will determine which engine options are available.
So...... what's your budget?

Would depend on the equivalence factor applied to rotary engines by whatever body regulates the race series the OP runs in! Is quite likely not
considered under 2.0L.

It's a very good point, if the budget is large enough I'll suggest a
Millington Diamond or for really good sized budgets a, RST-V8.

...except that it has worse performance than a car engine!

Budget is £1000-£1500ish, flexible if the right package was available!! Over 2.0 is allowable but must be 2 valves per cylinder sorry I didn't
make that very clear

Except the full quote was
"Ouch!! 100Bhp/litre NA.....

That's just a car engine in a bike. Ain't anything near 100Bhp/litre

RST-V8 is the closest thing, pretty much two bike engines mounted in a V (that said only bike cylinder heads are actually used, the cylinder
block/crack case is bespoke).

I've just about managed 200bhp with my ZVH engine (but not on that budget).....8v, Ferriday bottom end (£1300)...Ported head £350, kentCVH27 cam
kit (£290)..and fuel injection with GSXR TB's......
But, If I'm honest, it was more luck than judgement...I was expecting more like 170-180bhp.......

Bike looks awesome, but couldn't see any engine- specs on the linked site or what engine work (if any) had been done.
Sure, it's got great torque figures straight out of the box (for a bike engine), but the engine weighs the same as many car-engines which
produce just as much torque, but a good bit more BHP than the 120 of the Rocket III.

One good thing about engines that have been "done to death" - so has all the costly development and mistakes!

duratec 2000cc is good for 200 brake with cam and throttle bodies with a 6500 rpm red line but judging by my mates experience i wouldn t strip the
engine unless you really know what your doing!!!!

I've got a nice quaife 4 speed rocket box - HEAVY DUTY model, synchro, square cut, close ratio gearset, 2.04 1st, alloy cover.
Could sell . . . . .

turbo pinto,std pinto second hand turbo all the bits 600quid ,you can run 12psi boost that means 200bhp ,you can get more but you might do a pisto or
two,thay have been known to handle 18psi ,"by the way this is on std internals"
turbo pinto power
ps look at tourbosport furom,look in pinto xflow bda
just read your post no turbos doh,
red top my mates got one in his super stock!had it on the rollers today 212bhp@the fly175 @wheels

They'll handle that for a few miles, but not for long. Reliably the max is 8psi on stock internals. Forged low comp pistons would let you run
18-20 reliably.

I run a 13b bridgeport rotary engine in my westy(well I will when its finished) Butbthe engine cme from my 1st gen RX7. Its N/A and has about 230
bhp.
The rotary equivilance for sprints and hillclimbs is 1.5 sooooooooo 1308ccx1.5=1962cc ish Now lets not get into any argumants etc about swept volume
blah blah blah but I have been very succesfull with the old rx over the past 3-4 years that the desision was taken to do this as I wanted to beat all
of the piston powered 7s not just a few of the..sorry I digress

Don't know why you don't go turbo, 200bhp any other way is gonna cost you thousands, that would be straight out of the box for an £800
SR20DET engine, and even the cheapest mods would get that to 250bhp for about £400.....
Mine will be around 280-300bhp for about £2k total ...
If you're not living life on the edge you're taking up too much room.
