I know they are a WIDE motor but...
Has it been done?
Is it possible?

i reckon it would be nearly unpossible....

can i ask why?

Free 2L impreza motor and gearbox + my other swb i'm building needs a new engine.

Anything is possible if you have the budget and skills.

But it would just be the start of the mods. Not a single remaining part of the driveline would withstand that sort of power and torque.

EDIT: NA EJ20 is only 100kw. Should be ok if you drive nice.

sell the boxer & put the money towards a G16

Boxer engine would have to be wider than the clearance between chassis rails? Measure it up, I'd be amazed if it would fit but would love to see the potential.

The tyres would rub on the heads on full lock. :lol:

Won't fit. The engine and gearbox would sit too high to work in the tunnel. You'd have to somehow mate another gearbox to it as well

I think Gwagen has done the measurements and confirmed it to be impossible to fit into the engine bay for what would be a suitable conversion. Just put a commodore motor in you know you want to ;) .

Post subject:  Re: Subaru engine in a sierra?
I'd rather out in a 1L than a commodore motor!!!!
Time to get a g16b. My mate has an auto lwb bit for sale at the right price, will the auto fit in a swb sierra??

use the drive train from the subaru & make it AWD

:rofl: :rofl: :rofl: :rofl:

It's gonna need a pretty big ruf and chassis extension to make that work

An EA81 or EA81T motor should fit been much narrower pushrod etc.
I fell in love with the older pushrod subey engines due to their indestructibility and power when supercharged.
A speedway one blew away Fontana and top racers years ago on methanol and a hillclimber did the same to much more sophisticated bike engined setups on a few QLD hillclimb events.

It fits well in a Suzuki Hatch FWD and RWD toyota W series box adapter are available for RWD only or for Toyota running gear 4wd.

Dont conform and put a g16 in. Do the boxer and make it the meanest sounding sierra on the planet

flat 4's sound like a soggy harley. :roll:

quad rotor is where it's at, sounds like a F1 engine & shoots flaming bees & hornets out the exhaust . 8)

Pretty sure the flames are from something like a bee*r rev limiter

Post subject:  Re: Subaru engine in a sierra?
considering it's running an aftermarket ecu, i doubt they'd tack on a bee-r limiter, but yeah it would be an ignition cut rev limiter. the big fire balls is just unburnt fuel getting ignited in the exhaust from when he lifts off.

Post subject:  Re: Subaru engine in a sierra?
why not go all out and chuck a 6 rotor in it in that case. good luck with engine longevity

Post subject:  Re: Subaru engine in a sierra?
a rotor if looked after like anything mechanical will last, 2 mates have rotors that were built in the early 90's & neither of them have had any of these so called "longevity" issues, one is a 12a extend port & turbo & the other is a 13b bridge port.

Post subject:  Re: Subaru engine in a sierra?
my point was. a rotary in a 4wd is kinda pointless. just like a diesel in a sierra
Author:  atari4x4 [ Wed Nov 07, 2012 3:36 pm ]
Post subject:  Re: Subaru engine in a sierra?
why's that, cause they have no torque?

the link is broken to the dyno sheet i posted but this was in the youtube thread

Rotaries have :no: torque


i call BS, on that one... they have a very flat torque curve.

700+ lb of torque from essentially a 1.3l
http://www.madazmotorsport.bravehost.co ... 2-2008.jpg


A 13b is the equivalent to a 2.6l piston engine due to the greater displacement per revolution. If I read this right
http://www.drivingsports.com/site/2008/ ... uivalency/

If I use the HP calculation of torque x rpm / 5252, working back from that Dyno sheet that car is producing max HP at around 1800 rpm. If that is correct that its heaps of torque and I will eat my own words.

ha i researched the shit out of this a while ago, might have even posted some links in the rotor in a sierra thread... they have more pull across a larger rev range and I think even starting lower? maybe? than a g16.

i agree shakes, that was my attempt at sarcasm, really should have used the sarcastic font

The dont they idle at 2g?
I think you will find that any rotary making good power AND torque from down low will be lumpier than a stroker and there for pointless in a 4wd.

Bye

yeah maybe when peripheral ported :roll:

stock 13b it will idle around 1000rpm

subi engines are a very awsome motor as fatzook said it would be a massive job but it would be fricken awsome if u could pull it off
