Yes i mean the triple rotor mazda engine too {not the turbo engine}.. I was talking of a friends car with a v8 of 4.0 litres , so using the vic roads rule from the capacity rule for engine size .. Don't know if you would be able to get the turbo engine road registered ?

i have looked into doing this conversion and i know it is straight forward the hardest bit is finding the 20B, how ever in n.s.w if it is to be road registered it can't be turbo charged.

"Has anyone done this , if so let me know"
So you asked if anyone had done this conversion .
Then ...
"just got a 20btt with a rx7 series 5 gearbox, modified hilux diff, microtech, t88
cant wait till its finished"
You say your in the middle of it ? So to help other people who mite want to do this conversion .. How about explaining , or posting some photos of how you are going to do this conversion . Because in looks like nobody else here has done this conversion ..or has found any information on it ....
Thanks ..

Wow that car is fast.... what sort of power figures are we looking at for that car? i know it flashed up 600ps but what does that equate too? What kinda 0-100 times?

When i put the figures into a ET calculator this is what i got...
with 900kg of car/passengers and 600ps/591.78HP at the wheels it came to 8.71 so i put it at the engine and its still 9.18 seconds  .

Yer i think i will use the stock diff , good for about 60-70hp at the wheels . No seriously i think the diff will have to be a little stronger than the standard unit , maybe even stronger than the one i am currently testing behind a sr20det powered ae86 . I will properly need a full floating rear ,kaaz centre or some think like that set up , wouldn't like a axle to break and pop out at speed .
Fuel system !! the fuel consumption would use the sprinter tank up it about 100klm or less with the car flat out on the track . So i think i will be using a custom drop tank set up with inbuilt surge tank , fuel pump ? i think fuel pumps will be more the case ...
maybe have to get stuck into mine and have i ready by the end of the year , really in no hurry ..

No seriously i think the diff will have to be a little stronger than the standard unit .
I think you need to read i little bit more into my joke about stock diffs , and if you think the jap diff will last with a engine which is like having a 4litre turbo , i cannot wait to see it when its finish . Seeing a stock jap spec diff hold 300rwhp plus ...

Sorry ..
"This is the problem everyone is going to encounter with this convertion in the land of kangaroos,"
As from your web page ..
So i guess i don't have to learn japanese
"heres a question for ya, what diffs do roteries use?"
Most use borg warner unit i thought ? which are made here , most people use modified hilux or vl or nine inch ford diffs here in Australia .

Can i buy that "the super-strong Jap LSD diff" We both believe this don't we ?

HYP04A, you're the one who needs to get his facts straight. I have never heard of a rotary using a T series diff (a la JDM-spec AE86), and with good reason - they're weak as piss. They can't even reliably hold the power of a 4A-GZE, and with the torque of a turbo 20B it would snap like a twig. I know several people with very serious rotary drag cars and they all use Borg-Warner or Hilux diffs, with the occasional Ford 9". But an AE86 diff? LOL!
I'm really looking forward to seeing this 20B AE86 when it's finished. Pity it only exists in your head.

hmmm, considering the T series is 6.7",
and the hilux is either 7.5" or 8"... and the hilux axles are about an inch thick......
 maybe T series is stronger 
a T series may survive if you treat it nicely, but an F or G will take a lot more abuse...
anyway, will be inteesting to see what happens when the T series breaks  get someone to take a video

i was gunna insert a comment about a standard 1g-gte boosted to 15psi breaking 7 t series diff centers in 3 months...
even with the kaaz center etc... the weakness becomes not only the axle but the input pinion gear, I ripped 6 full teeth off in one of my centers.
just hold a t series next to anything and you will see how weak they are.

I was talking about a Kaaz in a Borg housing , there have just started making these . For commo's .{those cars found in the land of kangaroos}
But really , seriously .. i have only found two pic of this conversion , can someone post them up ? they could be helpful { did i say that } for someone in the future .
And where did that video come from ???

why even bother driving the car with that diff, just save your money and do it properly, cause when it blows (which it will) you'll be the first one to complain about it being off the road again

Stewarts right. the 8" hulux diff is one tuff cookie.
ppls have been drag racing with them for years over here.
5000rpm clutch drops on 400+HP/400ftlbs engines 1.5 60 ft times.. but with that much power you need to swap the axle shafts every season they do start to twist a bit.

After the car is moving the strain on the diff is greatly reduced. However, it will break eventually from a 600ps engine. No matter what you do to it or how you drive it.
My friends 7.1" E code held up for a couple months behind a 12psi 7MGTE but it eventually went south. The power while moving didn't kill it. the burn outs and clutch drops did..

I did compare differentials of these two, few weeks ago. Hilux differential is bigger and stronger looking in every proportions, exept ford has bigger crown wheel(obvious). I didnt have axles to compare but axle splines were bigger and all around in hilux diff when ford had kinda three un-splined parts(probably doesnt make any sense).
I would choose Toyota diff, no questioning here.

i was hoping for more than just that one picture... so post up a pic of the 20B, and the reinforcing you did the other night..
what boost are you planning to run? or what kw or Nm will you need for 7 sec passes??
remember, maximum torque from a rotary will be around
Nm = rotors x 0.65 x1.8 x 100 x (1+boost)
ie rotor capacity x 1.8 x 100Nm x 1+ Bar boost
or more basically, a 20B will make 350Nm NA and an extra 350Nm for each Bar of boost you run (this is theoretical based on outputs of RX8 and race motors) but you must be getting 95+% VE to achieve these figures.
for power
kw = (Nm x rpm) / 9402
so.. what boost will you run? what rpm? what Kw are needed for a ... 900kg? car to run 7's?

from rough calcs on the net, assuming you have 2000lb car with you in it.
you'll be needing:
772hp for 8 flat
833 for 7.8
902 for 7.6
976 for 7.4
so assuming you need 800hp = approx 600kw
(and remember that these calculators are based on pretty flat torque curve V8's (compared to turbo motors)
600kw at what rpm? sayy, 7000??
that gives 805Nm
805Nm = 20psi boost (ASSUMING 95%VE, ie a well developed motor)
since you are doing it on a budget, and probably won't be spending weeks on a dyno, your VE will be more likely to be 85-90, which means you'll be needing to run around 23-25psi boost.
but this is only if car + you = 2000lbs race weight.
if you add 10% weight, you need 10% more power and vice-versa...
hmm, so. what turbo for 800HP?? thats AT LEAST a GT42/45 from Ray Hall (http://www.turbofast.com.au/sales.html)... $3.7K
http://www.turbofast.com.au/GTpictures.html
chances are you'll have less than ideal porting etc, so you'll need a 850-900hp capable turbo, and a wider torque band. as well as properly tuned rear end to actually get this power down...
anyhoo, sounds like a great project.. please update your site with pics as you do the work, i'm sure EVERYONE (well almost) will be watching you to see how it all goes

Stewart , You are still missing the point , with a jap spec diff this is all still posable ... Thats what the secret to the complete conversion seems to be . And all you need is $20grand .. Why bother with drag racing any other kind of car ??? With this set up if you spent another $20grand would it pull 4 seconds. And when you say tubed , are we talking of bath tubs at the rear for traction ...
Intensevil , Thats for sure , it only took every single angle and component to be changed on mine in the rear to stop wheels spinning at 130kph ... But i didn't have a jap spec diff , that must have been the problem .. You don't need bath tubs then ..
So can anyway host or post those photos i have ???

i don't think i am missing the point , was just trying to bring some realism back to the thread... heh heh there's some kind of 'posing' going on i just thought i'd crunch some numbers and see what would "actually" be needed..
T series diff heh heh...i think thats been sunk well and truly.. T series and 800hp??? ummmm....... hmm, lemme think...
hmmm, 20K...... i'd be building a minidragster for that..... probably only have enough cash to have a stock motor after that tho....
hell, rotary ppl spend more than double that on a half decent street RX3!!!
