3 Rotor, What would you need :)

[interloper393]

Testing the water...
Been chatting to a few guys (Mike and Neil) lol and loving the sound of a 3 rotor FD3, i was planing on putting together a single tub track car but this sounds much more fun
So apart from a basic car, what parts would i need to build one:D
Is it as easy as sticking 2 engines together?

Nope:confused: make way for deep pockets like £20+k makes one hell of a straight liner, if you want it to do trackdays add another 10-15k race car£££££:eek:

The other interesting question to add to this if a money no object then would be what would happen if you used the Racing Beat Aluminum Middle Irons instead of the stock stuff. What weight would a short block 3 rotor 13b ?

Sorry if this seems like a thread hi-jack !

20k??? you serious?? fdck me lol.. sod that then lol

[Ricco_04]

I didn\'t think it would be that much untill I seriously looked into it - and then seriously turned and ran the other way! :Giggle

Would be awesome and, as above, wonder what difference in weight there would be with the all ali engine?

a three rotor would be a 20B.lol:cheers

and im sure i have seen on the site that normski\'s car has cost well into the £30k\'s but it would be cool, as an alternative you could just buy a cosmo for way less than an fd ad have a 20B and LOADS of room for HUGE turbos like kev-yorks.:3gears-rh :Hammer

Can\'t you buy modified 13b engines that are a shorter block than the 20b. They arn\'t classed as a 20b (been told off in th past). As for the racing beat question:
http://www.racingbeat.com/FRmazda2.htm .They are lighter than the steel counterpart so maybe the weight distribution isn\'t affected the same in the engines stock position.

I think the amount of cash invested in normski\'s 20b FD is more to do with the car having perfect weight distribution. The 20b is much lower and much further back than the stock postion. This meant everything was custom made for it. A seriously amazing peice of engineering by pip. It was built as a track car with corners in mind, not just a straight line blaster.

the short block 3 rotor doesnt run primaries and secondaries like the 20b so not so good for a road car.   They are often P ported.

[Carl]

Short block 3 or 4 rotor can easily be made to run primaries and secondaries.
But the torque smoothness is so good all through the rev range that it is not really necessary.
