G'day. I drive a 83 Mazda 929 Coupe, and i was just wondering if it is "possible" to change from the 2.0 litre Mazda 4 cylinder it comes with to a EA-EB Falcon inline 6.

If it is possible, would it be alot of work, (would it even fit under the bonnet!) and how much does an average Falcon 6 cost? Also would the power upgrade be worth it? (The 4 cylinder Mazda engine only puts out 60-odd kilowats.... soooo slow up hills )

I dont really know the 929 very well but ill say this:

if its...

RWD: possibly...it'd take alot of work though

FWD: you'd be better off fitting a truck engine on a motorcycle...unless the car was converted into rwd

You can buy falcon I6's from as little as 200 bucks, but if you want to get a decent (say el xr6) engine they can get up to $1500. However it does all depend on the condition of the motor.

But IMO you'd probably be better just selling the 929 and buying a falcon...seeing as IMO theyre better

You'll also need an engineers certificate, and probably installation from a mechanics - which can cost up to 3k.

On top of that you'll probably scare the hell out of insurance companies;

Sorry, but for a car from 1983, its simply too much cost and effort; buy an EA or EB - I know of an EA station wagon for sale with an installed ED 4.0L for $3500, the ED engine had only done 90,000, plus the wagon also has a fairly new gearbox etc

For a car that sort of age there would just be too many hassles getting rego, insurance etc to justify it.

Thanks for the replys. Yeah that probabaly sounds like the best idea (Just buy a Falcon!).

A Falcon 6 wont fit (too long), but a Rotary will and so will a V8.

If you still want it street legal (and drivable) the rotary is the only option.

You could probably get a EFI Turbo Rotary (Series 4 or 5 RX7 motor) up and running in it for around $5k, maybe less. Would make a great sleeper, and would run atleast mid-high 14s, probably even 13s wouldnt be out of the question.

A rotary is the best idea! You know its gonna fit but theres stll the problem of grearbox, driveshaft dif etc...

depending on what model he has got it can be easy as i done it to a 82 929 all i had to do was change the gear box as mine was released in Japan with a rotar everu thing else was setup for a rotar from the factory. they are a leathal car with a 13b turbo in them

I think that the 2 door 929 (pop-up headlight model) was available in Japan with a turbocharged 12A rotary.

maybe a celica GT4 engine, stock with 185 fwkw, and pretty cheap (2500 or so) and that will only have 20k km's on it

you will have to convert it to rwd but it is an awesome engine, can handle more power than a SR20 on stock internals
