whats the best engine to use?

[cwin]

Hi
I have a fd 3 series single turbo that i use for trackdays,I want a spare engine which i will get built by wgt, what i need to know as i am new to rotary\'s is,are the rx8 engines any better to covert to a single turbo and will it mate straight to my gearbox and engine mounts.You can buy a 12000 mile unit for around £1500? which seems a good option if it can be used.
Regards
Craig

Not sure about the rx8 engines, havent heard of anyone doing that.
I think the best engine people are using for big power with single turbo\'s are the RE engine out of a Cosmo, because of the bigger inlet runners. Its possible to source one for around £1200 needing a rebuild and depending on porting and turbo used will get over 500fwhp.
Do you have any pics of your car sounds very interesting mate:3gears-lh

I am no good with computers but someone posted pictures on a track day at oulton park on www.pistonheads.com if you click on Forums and look under the heading \'\'track day and driving experiences\'\' its on page 3 again under the heading \'\'anyone going to oulton 20th feb\'\' (don\'t know how to do the link thing). Plenty of comments about the Flames!!!!

Below is a pic of your car mate. I saw it at Pips too - very nice set up. I am pretty sure the last owner was around on this forum.

Anyway, the RX8 engine will not fit. There are too many complications such as the mounting of engine, your turbo\'s too etc will not fit.

Your best best is to have a 2 Rotor Engine (13B REW) from a RX7 or a Cosmo. Have it ported, maybe dowelled too then add a single turbo to that. Or it is also possible to have a 3 Rotor Engine (20B REW) fitted from a Cosmo in NA form producing circa 400hp and excellent for track or in turbo form producing anything from 650-800hp. Altough the 3 Rotor engine conversion is VERY expensive.

why not to install Honda2000 engine, easy rev to 9000\'s and cost about £1500+

Be guttless in comparison surely?

sorry, meaning?

The car is already making 348 rwhp 410 flywheel? so i an happy with that at the moment, What i want to do is have a spare motor built up so i am not loosing out on track time (10 track days paid for in advance).If i am going to have a new one built i want a motor that is built for the track ie big hp.

400hp is pretty good  and it\'s always down to the driver/car set-up at the end of the day!.
If it\'s me, set up is the first priority!

sorry, meaning?

torqueless and underpowered.

A large streetported engine with decent size turbo will show 500 fly at relatively sensible boost (circa 1.1bar) and still show positive boost at sub 2k rpm and full at 4 -4.5k rpm. If it is a track car it could be bridge ported but I have no personal experience of one. I think a bridge port is hard to map for the road at lower revs but this may be very low on your priority list. I too was considering an 8 engine at some stage but the fact none of the bigger tuners have gone down this route sort of pre answered my question.

Bridgeport is an option but then you car will be very noisy and loud. Getting on to track could become a problem.
