its a bit useless to use facory specs as the jap limit is 206 kw and i have no doubt a 20b makes a shitfull more than 206 kw as does a 1j as far as the cosmo goes umm i think these STANDARD SPECS are a little more realistic 0-100 in 6.2 secs 1/4 mile in 14.3 secs http://cp_www.tripod.com/rotary/pg09.htm also the times quoted for 1j soarer are for manual the auto does 5.7 secs in standard form and weighs 1670 kg for starters this is a stock 1j (no twin pipes with 3 inch exhaust) this is 340 nm of torque and 189 kw @ wheels interestingly this is the same figure most stock 1js get on toymods dyno which is approximatley (for auto) 484 nm of torque and 270 kw @ flywheel . max torque is at 4185 rpm and with twin pipes max torque is at 3700 rpm with twin pipes a decent intercooler and 16 psi over 650 nm of torque has been produced and 342 kw (240 kw @ wheels) my wifes cressida weighs 1580 kg i think this clears up the 0-100 issue http://home.kooee.com.au/celicamad/4.7%200-100.jpg i have raced a boosted (18 psi)rx4 with 20b fitted which had aftermarket managment .out of 10 runs i won 8 and the other two runs he wheelspun .his best 1/4 mile on street tyres is 12.95 but it was impossible for him to repeat these times on the street it was making 290 rwhp in 4th gear ( i quite believe that) i also belive that with a decent setup this car could run faster and the 20 b made the 13b 's id run look like hyundai excels in performance difference a 20b is barley a 1j let alone a 2j as far as comparing to a stock 2j ...well 2js are sequential and in a 1700 kg supra in stock form do 0-100 in 4.6 secs and can do a 13.1 sec 1/4 mile and weigh around 1620 kg and thats a non vvti 93 twin turbo model thats kind of kicks the shit out of a cosmo specs here http://www.mkiv.com/specifications/93_brochure/199 3promo.jpg with stock turbos in twin mode a u.s spec supra can run into the 11s .but thats in a 1700kg vehicle . the graph below shows the before and after power from a boosted stock 2j running in twin mode .The 600 odd h.p is on stock internals with a large single turbo and re-chipped factory ecu 421 rwhp is 314 rwkw and thats 392 kw @ flywheel(allowing for manual).ON STOCK TURBOS AND STOCK ECU i belive that a 20b is rarer and more expensive than a 2j BTW A 2jz complete 1/2 cut $3500 auto asian autos slacks creek 0-100 the auto is still quicker than the manual .Its the 6 speed box thats worth a shitfull i think around $3,000 considering a 1j complete is only $1900 at asian autos again and they are only 720 mm long will fit in an ra 23 celica and can do 0-100 in 4.7 secs in 1580 kg Cressida imagine how an RA23 celica would go weighing only 1200kg with the 1j and a 9 inch diff .thats 380 kg lighter ummmmm i think sub 4 secs is not out of the question they fit!!!! its easy and a $5,000 total conversion see here http://home.kooee.com.au/celicamad/paulbuild5.jpg fits just nice in my celica ...note the distance to the front of the car ....
