Dont think i would ever bother putting a rotory into a 4wd it just dosnt make sence to me. They have no power down low , they flood (old 13b's and 12a's) if you leave them idling in one spot for to long so it wouldnt be a very good rock crawler, when you thrash them it cost's you $$$ last time i checked they were asking about $1700 for the housing and $1500 for the seals, though that was a while ago. Dont know how many people on here have driven rotorys but i found there realy gutless driving up hills on the road so i cant imagin what one would be like out in the bush but a turbo would fix that problem pretty fast :D . or you could just go a 13G or 20B tripple turbo ive seen a zook with a 454 so if they can fit that some one could do it.

mate of mine has a 13B ser5 turbo motor and box in he's WT SWB zook
very very fast :twisted:, std transfer holding up for now but everytime right foot goes down it breaks an axle or diff !!! quite torquey with the turbo though

it fries tires in 2nd and 3rd under accelration on the tarmac !! :shock:

need BIG BALLS to drive it !!

to guts down low, bollicks

i had a 13B 6port, with the actuaters removed and a 48mm DCOE webber . would pull a burnout at a 1000 rpm in 3rd gear, it idled at 1200!

this one with the side draughft would pull ok, but will be hell thirsty. mine used 20L/30km, way too thirsty for a 4by

Suzuki Vitara SWB from 1995, 1997.
Hard-top/soft-top, 2+2, 2dr

G16A 1590cc petrol 4cyl EFI 4v/cyl SOHC
bore: 75mm, stroke: 90mm, c.r.: 9.5:1
power: 71kW(92.3hp) at 5600rpm, torque: 132Nm at 4000rpm(97ft/lbs)
transmission: 5m/4a, part-time 4WD

Below is an engine dyno chart comparo for a std rx7 13b and a new renesis rx8 1.3

even the std 13b makes the max torque of the zuk engine at 2700rpm, waaaaaaayyy earlier inthe rev range and then keeps making a nice flat torque curve. it still makes the same hp earlier too. and thats with all the polution crap on it too, put a decent exhaust on them and they make really big power gains.

umm i dont know if im reading that chart right but dosnt it say
MAX POWER 126.6hp and MAX TORQUE 109.1 for the rx7???? so your the zook motor puts out more torque. Also im not knocking rotor's they make great cars its just that TO ME there are other motor's that i think would be better suited to go into a zook like a 454 :D .

sorry didnt explain dyno figures in ft/lb so rx7=109ft/lb and g16 zuk=97ft/lb. that why i said it makes the 97ft at 2700rpm compared to the zuk motor which you have to wait till 4000rpm to get the same torque.

should have explained it better :oops:

NP didnt realise they were different.
