Even easier is the search key, as this is almost a daily question...

ok i looked idk if i used good key words but nothing came up could you just link me to a forum that tells me what has to be done to get swap down

No, it's not "easy". You have to knock out the tranny tunnel to fit things, and you will also need an ecu, wiring harness, and a transmission. The R154 will not bolt up. Above all else, it's an expensive swap.

ok thank you, i thought of a new idea and was wonder would it be hard to supercharge mah 87??

Jeeves · 08-17-2005, 09:05 AM

There is not a supercharger for the 7m, so yes, that would be more difficult. Besides, who likes the idea of having to buy a new pulley just to make more boost? ;-)

Turbocharger > Supercharer

but supercharger gives you more toque and i think i found a way to make supercharging it fair easy, but i'm thinking supercharging it will make mah computer go insane or something no so good happen, but the final question i have at this point, are the injectors on the 7m-gte and 7m-ge the same and or close to the same, same goes for internals

Jeeves · 08-17-2005, 04:49 PM

They are not the same. Toyota used the 290cc yellow top injectors from 1986.5-1988 and used a 315cc lime-green top from 1989-1992. Factory Mk3 Turbos have 440cc injectors. On top of that, the ECU won't know what to do with boost. The block also has higher compression and lacks oil squirters which would be used to cool down the pistons in a forced induction motor.

Sure you can do it, but will it be as good as a $800 swapped JDM Turbo motor? No.

I made 315rwtq and 262rwhp on 9psi. Superchargers do have faster low-end torque, but the fact is, you can't easily supercharge a 7M. Besides that, the fact that it's not done would say that it's either 1) Not easy, or 2) Not as good as the turbocharger.
