Why 1Jz-GTE?

Well it seems like alot of people have or are swapping there 7M-GTE to a 1Jz-GTE. This is probly a stupid question but why? Look at this i got this off Wiki so ya...

2.5L 1Jz-GE 200 hp at 6000 rpm and 185 ft.lbf at 4000 rpm.

Compaired to the 7M-GE

3.0L 7M-GE 200 hp at 6000 rpm and 196 lb·ft at 4000 rpm.

Isnt the 7M Better?

With Turbos
2.5 L 1Jz-GTE TwinTurbo 280 hp 272 lb·ft

3.0 L 7M-GTE SingleTurbo 230 hp 250 lb·ft

Sure the 1Jz-GTE has 50 more hp and 32 more lb·ft but is it really worth the cost of a new engine? Wouldnt it be cheaper and easier just to buy a better turbo for the 7M-GTE?

I brought up this topic because my 88 Supra has 170,000 (KM NOT MILES EH) on her now so the HG will blow soon and i'm wondering if i should just screw the 7M-GTE with its blown head gasket and get a 1Jz or rebuild the engine/turbo i have and add a few mods.
