that will be too much power thru the front wheels i think it will be hideous to drive and control

Yep if I could get the power differance between our cars down to around the 180bhp mark there should\'nt be a problem driving round that:rollin
 
As for putting big power through the front wheels, theres quite a few CTR\'s running 500bhp+ that seem to work ok on track and when you look at the power/torque curve of the particular engine I\'m using it seems to come on boost and produce it\'s torque very linier unlike a lot of piston engined turbo cars which come on boost with a bang and have massive amounts of torque in the mid range which does make a big power turbo cars hard to drive over a lap.

I think you will find 400bhp far too much for fwd. It\'s tried and tested that there isn not much point in anything over 250bhp sometimes a little more depending on set up.
500bhp ctrs that i have seen have all been drag set up with very wide full slick tyres. And a lsd is absolute must or your just smoke 1 tyre all the time.
Good luck with the build.

Its a different Craig under Cwin i believe, he was looking into buying my satin rx7 and met him a few times very nice guy, and has the seriously quick 20B that Normski had :god


Looks like a awesome project you\'re undertaking there mate, love to see some times and figures once you have completed the project, going to be a very quick Peugot !!!!!!

I will put it simply. If you want to wreck a good 306 then give it to me and I will rally it.
The rotor conversion will not work, It wont handle,It will upset the balance of the car, you will have to upgrade the brakes if you dont want to kill yourself and amongst other things no matter what other ****e people tell you it will cost more than you think. Have you sat down and set a budget and then doubled it plus it will not make the car worth anymore.
If you go ahead and build it(fair play to you) I will meet you at a drag strip and put my Series 1 Rx7 with 250bhp motor up against it just for a laugh
Good luck

So you don\'t like that idea then !

I\'ll be proving the conversion on another car I\'ve got, not because I\'ve got any doubts about it working, just so I can keep my track car going while I tinker with the other one and iron out all the problems. When I put it in my track car I want it to be Saturdays job.
I cant understand why you seem adamant it wont work and your making assumptions about me and my car. For instance my brakes are straight off a Scooby WRC although at the moment I\'m only running 305mm rotors there\'s still a margin left in the brakes, when the engine goes in the it will be running 350mm rotors as I\'m moving up to 18" rims this year.
I haven\'t even considered a budget as I\'ve got everything I need to run the engine when I bought it. I also own and run a machine and fab shop and I\'ll be making everything else for the conversion myself and besides anybody that modifies any car know that you\'ll only get a fraction of what your spending back when you came to sell it. The 13b wasn\'t my only engine option, I\'ve got a brand new 285bhp big bore Mi16 engine sat in my garage that I built couple of years ago that would be great in the car but I\'m convinced the 13b will suit it better and be give me less hassle in the long run and improve the balance of the car. Thanks for your input and it would be interesting to see how it would go on a drag strip but the cars built for going round corners really.

save yourself a world of grief and use the m16 lump the rotary will not take constant abuse at the power levels u have honestly..do a search they have a tendency to pop more than ur average piston car

chrisJDM

depends which piston cars you are refering to, i have had my rx7 for 2 and a half years with no problems and i know guys with imprezas and evos that have gone pop several times.  I dont drive my rx7 alot but when i do i dont take it easy hehe  im running around about the same power as them aswell

mi16 engines are very good engines thou and are built for motorsport, and you can get 300+ bhp out of them, i know a few guys with stripped out 205\'s with tuned up mi16 lumps and they are very very quick cars round a track especially tracks like castle combe where you dont play with top end its more bottom and mid range.  Ive seen plenty of 205\'s take on porsches and cars of that caliber with ease round castle combe

400+ bhp in a stripped 306 will be very very quick, good luck with the project and i hope it all goes well, and keep us updated :Thumbs-up

No good sir I am not making assumptions about you at all.
But you have now enlightend us on your engineering skills, something you didnt do earlier.

Sorry but i think thats so untrue. With the the rotary being the only japanese engine ever to win lemans, i would take that statement with a pinch of salt.  Kinda make me wonder why the 787b was banned in the first place? Rotary\'s make great race engines. With the right mods, they can be made to be very reliable. Has no one seen the vid of the rx7 redlining for like 10mins? http://www.youtube.com/watch?v=GoGAdxl9l0E As for the conversion,   I would still put it in the pug, just in the back driving the rear wheels.

I think with this chaps engineering background rebuilding the rotary should not be an issue and is cheaper to rebuild that the piston version so all should be well if it does go pop after a while.

Deffo wanna see this Pug fly with the rotary in it, which turbo will you be running as not seen one mentioned yet ? the 400bhp figure would have been turbo\'d :Thumbs-up

it depends if the 407bhp figure is flywheel or wheels, if its flywheel could just be a highly tuned twin turbo.

Love your "can do, will do" attitude crf450!

Can\'t help with thechnical details of maiting engine to gearbox but whatever you do make sure you factor in enough space for a big rad and intercooler.

For track work most people run v-mounted setups - they tend to work slightly better than front-mounted intercoolers (it\'s difficult getting enough throu-flow on the FMIC to the rad).

Other than that ensure the map is erring on the safe side and you\'ll have plenty of track miles out of it.  It\'s usually the ancillaries that go and take out FD engines - 15 year old fuel pumps and the like so treat them well and you\'ll be fine.

Good luck with the project and keep us updated!

Looks great! stick to your guns, it may or it may not work. wont know untill you try huh :Giggle

Good luck

I woof in your general direction.
