13B-REW vs EJ25 Turbo: Which is the better swap ?

[Ryosuke]

Rotary vs Pistons
Mazda vs Subaru

Can people share their experience with either engine and describe Driveability , Economy , Speed , Cost and of course.... how easy or hard the swap is for a Nova

Thanks

Look at the my car section "British Eureka"

Mazda MX6 2.5L V6 on VW transaxle.

10 years on the road, 51,000 miles later still going strong.

Fast...yes
Economical...,...drive like grandad....yes, drive like teenager........no

Tyres on rear do not last long!!!!

Yeah, but it's not a rotary is it

Both motors will make a Nova/Sterling STUPID FAST

Before commenting on these engines, why did you choose these 2?? and why turbo's??

Your 0-60mph times may not be that great due to the fact of how light the car is and how much HP these engines put out. You may be smoking the tires more than going forward when trying to set low et's

Both will require some skills to install.(welding, fabrication,etc)

Even though companies make adapter plates for these motors, the install is not a bolt and go install

As has been found in the past with many different combinations, more power does not always mean more performance.

I am not a fan of powerful conversions, apart from the fact they are mainly undrivable, I have seen so many not see the light of day, much less end up on the road as the budget and technical aspect gets out of control.

As Brett says, stomping on the 'go pedal' and swapping ends, maybe fun a couple of times in a car park but if you really want to 'drive' the car without having your heart in your mouth all the time you have to balance power and road holding (suspension) in such a way that it behaves within drivable limits or you will end up in a ditch or worse and will not be fun for long.

As far as engine type goes, I wouldn't entertain a rotary, light and compact and simple in theory, but not so in practice, they never really caught on, I have worked on a couple of double rotor engines, didn't like it. Great where power to weight ratio is a factor but Subaru has it when it comes to bolt on stuff.

Personally I like the idea of a Rotary engine in a Nova. They have a turbine smoothness (I'm led to believe) and because of their simplicity are very lightweight and powerfull. They seem to be popular in Australia's Eurekas. The downside here in Britain is that the engines are relatively rare and have a reputation for unreliability. Personally I find the power to weight ratio of a 1300cc twin port Beetle scary enough in the Nova though There are times I would like more power.

Isn’t there a way to put down power and great handling e.g Throttle control , Adjustable suspension ... e.t.c ?
