Mon, 09 June 2003 04:03 Considering i have actually measured both engines i can tell you for sure .that the two blocks are VERY close in lenghth in fact only about 30 mm longer for the 1j . the TOTAL lenghth of the 1j is 720 mm (the same lenghth as a 1ggze) .from the front of the pulley to the front of the engine is 90mm .making the engine 610 mm long you need more room for a 1j its but as i have already explained the front pulley is responsible for a lot of this lenghth The gearbox weight is rear of the front wheels .adding weight forward of the front wheels is what has the biggest effect in the actual handling again the actual geometry of the 1j has the mount positioned more frontward on the actual engine than a 1ggte .in fact the centre of the mount is only 29mm from the front of the engine .depending on which 1j is used but a front sump is needed for the conversion anyway did it actually occur to anyone that the 1j is the same weight as the original engine YES i have done this conversion (or should i say helped someone else do it ) i will say again the engine CAN be mounted lower . the original mount bracket was removed from the crossmemebr and the 1j mount and the actual front pulley was located some 10mm further back than the original engine .the rear of the engine is 10mm from the firewall i think i know the difference between a 1g and a 1j and a 2j ive either done or assited in 4 1j conversions and about 5 1g conversions The front end of the car sat approx 25 mm higher than with the original engine Quote: I don't know much about 1JZ mounts, so I can't comment on it sitting lower.. so how can anyone that hasnt actually ever measured this engine .never attempted to fit has never weighed one . or even seen one in an ra60 comment on the handling . how do you know its harder have you even tried it or serioulsly looked at it obviuosly not you havent even measured one as far as how much differnce an extra 20 kg would make in the front of a car ...well you obviuosly have never even experimented with this . CONTRARY to your wild guess on weight distribution .removing the battery (11 kg) fitting and all allloy radiator saved 2 kg .removing a section of the front bumper about 2 kg saving .so actually lightening VERY forward of the front wheels .and 11kg was all on one side . made absolultey no difference to the handling what so ever when you fit an engine MUCH lower it has a huge effect on cornering .your not pusing the weight from as higher point ..less mechanical load on the suspension Finally using scales to weigh each corner of the vehicle .it was determined that the 1j casued the rear weight distribution to be slighlty more and the front slighlty less . the front was lowered 1 and 1/4 inches the rear 1 inch . a larger rear sway bar kyb shocks all round and a slightly larger front sway bar .and the car handles VERY good . consdiering that in standard form it handles like an absolute bucket of shit .and BEFORE the susupension was added it actually handled BETTER than before id say your WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAYYYYYYYY wrong the most interesting part is the 17 by 7 inch mags with 215 45 17 front and 245/45/17 rear fitted added more weight to the car than the entire conversion It still amazes me how people can form an opinion on an engine conversion based on a wild guess of engine weight ,lenghth ,positioning and physical geometry The whole idea of these forums is to help other people to make the correct choice .and give them advice that will guide their decision of which engine and the difficulty of conversions etc I Think it is irresponsible for someone to give advice on a conversion they have NEVER done NEVER seen AND NEVER even Made basic measurments to see how well it would work Interseting how a lexus v8 can be fitted to a mazda mx5 and the geometry of the conversion be so good that even with the big weight difference the car handled better than ever all round for bang for bucks the 1ggte is a much cheaper and easier conversion however .if youd like an extra 100 h.p at the wheels and about 150 nm of torque more then fit a 1j P.s the entire conversion including wiring was completed for just under $4,000 .t THE HANDLING IS NOT ADVERSLY EFFECTED [Report message to a moderator]
