AE85 AE86 - Rotary. All Opinions WELCOME!

[strx7]

If you can find one with a 6spd box, loom & ECU attached ill be real keen! Haven't seen one come up on TradeMe yet, will ask around a bit.

IF you want a price on one ring either Any Mazz Spares in Hamilton or Roto-Wreck in Whangarei (i think he advertises on TM)

i've had the chance to drive a couple of RX-8's at work, the engines are sublime - brilliantly smooth acceleration, they just feel like they want to rev forever.

Ok, i sent a message off to Mazz Spares and they said they didn't have any 13B-MSP's up for sale. So i asked them about a complete 13B-REW setup of motor, box, loom & ECU and they said $4k for a Series6 with 41,000kms on the dial.

As for Roto-Wreck, couldn't find out any details....do you know there number??

[cogent]

try and get a series 7 or 8 engine, the turbo system is not as complex, is more responsive/better spool time, make more power and are over all better revisions of the 13b-REW engine.

[mikeBrotherd]

I know what you mean, the early 13B-REW motors only made 230Hp, not great when you compare it to the 13B-MSP 232Hp

[Trls250s]

230 HP is better then a Generation 1 3sgte from a GT4.

I say do it. I own a 85, and id do it if i had a rotory, or even a S2000 motor.

a mate looken into a brand new RX8 motor for his B1600 from mazda and the "long Block" was $4500, not too bad for a brand new engine (may have been trade price tho)

An auto one maybe, the early ones were rated at 260ps. Plus they have an assload more low end torque than a renesis motor.

try Brent at Maztech Partsworld in Rotorua too. he might have something.

[tsoob]

do it man!!!

I think you may underestimate how well it will go. Set up right it will have a fat broad powerband. Easy low 12sec car on standard boost with traction. Add some good brakes and a Hilux diff conversion and the $$$ will be up there, but necessary to do it properly.

Hopefully it stays together!

Same here, Those engines are wicked little units, not as quick as a Mazda 3 MPS, but still have mint acceleration. Would be a whole new monster with a turbo.

the interior makes you feel like a fighter pilot.

Yea, I have to agree on the Renesis engine. When I drove one, I found myself cruising at 4,000RPM without realising. Hah

They may make quite a bit of power, but you've gotta remember, its not how MUCH it makes, but how it makes it.

Also, with N/A engines, you find that the torque (in Nm) is often relitive to the engine capacity. Eg a 2 litre will make between 190Nm to 210Nm. A 3 litre is around 290Nm to 310 Nm etc. There are exceptions, but this seems to be the general trend.

The Renesis engine is a 1.3l and makes 211Nm. But remember, in a single rotation, you get 2 combustions. So the capacity may be 1.3l, but its actually producing power around what a 2.6l should be. So the torque is actually on the lower side, whereas a piston based 2.6 would produce more around the 250Nm mark.

Just something you should note, as torque is important.

But if you're chucking into something light like an AE86, then you shouldn't worry too much anyway, but always good to keep in mind

Sidenote... my mother in law took an MPS for a test drive in the weekend... faaarrrkkkk, scary crazy fast... one day I hope that my little RunX will pull like that.

So the capacity may be 1.3l, but its actually producing power around what a 2.6l should be.

I think what you meant to say was

"It's needs to burn as much air/fuel as a 2.6 litre piston engine, to make as much power as a modern 2 litre engine."

i think it would be a brilliant little conversion.

my preference would be standard renesis engine, standard exhaust, ie quiet , and a nice tidy standard looking ae85/6.
you dont need all the extra ponies modifying the engine would give in a 900kg car and it makes it a load more reliable.

im a big fan of standard looking conversions done properly.

nothing like a loud bridgeport/j-port/pp pulsing away though

yeah... thank god aye.

I like your style! Your going to hate me for pulling this beautiful converson i did,


Also i think were all on an agreement here that the weight of the Trueno is hardly going to be a problem with this choice of motor....

yeah... thank god aye.
