Re: 3SGE -> 3SGTE (ST162)	Fri, 21 January 2005 08:28

Hi Josh, Searching the forum for info on this will reveal plenty of threads full of info, but heres some to get you started. the 3sgte motors (Gens 1,2 & 3) are only available in the gt4 variants of the celica i.e. ST165, 185, 205 and the SW20 MR2. The MR2 motors apparently need a bit more work converting them to a front mounted setup, but can be done. All 3 generations come with top mount IC's as standard. the 165, 185CS and 205's have WTA (water to air intercooler) and the ST185R comes with ATA (air to air intercooler) so if your going for a front cut off a ST185R you will need to adapt a bonnet scoop, or install a FMIC. The others can go straight in, but I believe vents in the bonnet would be a wise idea due to the heat generated by this motor. All 3 motors share the same basic block design which means they should all mount up the same (I may be mistaken as I believe the 205 or Gen 3 3SGTE has a different sump setup which may indicate a change in block design. An mr2 gearbox may also be a wise investment as its setup for 2WD and is deisgned for the additional power/torque of the 3SGTE (any guys here more familiar with the different variants of gearboxes can confirm or deny this. The other major thing is wiring, you will need a different ECU, and wiring loom. MR2 wiring looms are quite different and wont fit straight in a celica without some serious cutting and rewiring. As far as im aware ECU location is the same in all 3 models so holes in the firewall and wiring lengths should be close of not the same. As far as recommending which type to go for its up to your taste and budget. 165 (1986-1989) has a smaller WTA intercooler than the 185CS or 205, small port head and has a single entry CT26 turbocharger running 8-11psi stock. 185 (1990 - 1993) has T-VIS (toyota variable intake system) large port head, larger WTA or ATA IC, twin entry exhaust manifold and CT26 also running 8-11psi stock 205 (1994 - 1998) has the same WTA IC as the 185CS (205 owners may be able to outline a difference i have overlooked) no T-VIS, smaller ported head but apparently has the highest flowing manifold-head setup of the three and a larger CT20B turbocharger running 8-13? PSI stock (please correct me if this isnt accurate, but i know its a higher level than the other 2 gens) obviously they newer gen motor you get the bigger the dollar sign will be, and if your attempting a conversion, best to just get the half cut so you can be sure you get all the peripheral goodies and pipes needed to make it fly. If anyone has spotted a flaw in my information please ammend it as this was off the top of my mind while sitting here bored at work. G/L with the conversion....post it in members rides!
