not according to that last post he doesnt...
1) he prob got rod knock because of the bhg. the coolant mixing with the oil will contaminate the bearings and quickly destroy them. this is the main reason why people who get bhgs and do quick fixes end up with rod knock shortly thereafter.
2) 7MGE's are actually MUCH LESS likely to get BHG then their turbo counterpart. lower cylinder temps is the main reason. however moreso kids modifying and slapping a mbc on the turbo car and upping the boost without proper up keep, therefore detonating, and therefore bhg is more likely the cause nowadays. obviously the low torque of 56ft lbs from the factor doesnt help much either.
3) the 2j comes in the sc300 in na version in the US too. swapping in a tt version is not hard whatsoever.... swapping in a 1jz into the mk3 isnt necessarily hard...its actually rather simple if you have any knowledge of cars and wiring. what do speedo and diff gears have to do with ANYTHING? they will all work together. in fact the US version of differentials is better suited for the 1jz then the 4.10 torsions they come with in japan. the lower 3.91 and 3.73 diffs of the turbo US cars are better for the high revving 1jz gearing. the wiring takes about 2 hours if you know how to read diagrams and can solder.
4) i dont know why you would need an entire front cut to put another 7m in your already 7m equipped mk3? just buy a jdm engine OR IMO your better bet would be to rebulid your current 7m. this way you have a brand new engine and not a beat on used jdm one you dont know the history of. i cant tell you how many times ive seena jdm engine get bhg and rod knock within a month of being installed. they just dont take care of them over there because they dont care. and um newsflash the 1j CAME IN the mk3...so mounting it is as simple as mounting the 7m (granted he would need to get either a 89+ crossmember or the BIC mounts to use his current crossmember.
5) celicasupra.com isnt going to help him much since he has a mk3...he needs to look at Supraforums.com and supramania.com ..... you saying that makes me wonder if all this info (at least the relevant info) is you thinking he owns a mk2 but he clearly states 88 which is mk3. even still a lot of your info is incorrect completely.
sorry for the long post but i just needed to clear some things up.
