Right, the M7 engine is an inline 6 cylinder and comes in 2 variants eigther as an NA with 205hp or the turbo version at 235hp, also the 'early' MK3s had the older 'Toyota' letter badge on front and the younger ones (from '91 or '92 I'd think it was) came only with the known Toyota logo, that we still knew today. :D But at least for me the A70 is far to underrated despide the all over A80 (MK4) and its 2JZ. For sure - incomparsion there are 'tons' more in aftermarket parts etc. for the MK4 but it isn't impossible to bring a MK3 Supra up to +300/400hp but you have to do more efford to it by not only hanging a bigger turbo in it but to make the M7 engine captable of withstand the plus in power much earlyer (best from start on...^^) than on tuning a 2JZ in comparison to it. 'The M7 was build but the 2JZ was forged.' - that's why it'll cost more, to proper get it modified. :P
