and why was it put in a family wagon lol

how does it compare to a gen 2 3sgte or a rev5 mr2 tubby tuning wise

If you change the turbo too.

Apparently spool time is faster!

I think I read that the internals are slight different I wonder if that's for better or worse,(can the stock motor handle more than the stock rev5 tubby)?

it spools quicker as it has a slightly smaller turbo
sure, coils newer tech, also at£100+ a pop to replace, are more expensive than a set of leads by a long way when its time to replace.
Unless you are talking about silly power levels, oem ignition setup is fine
i see the appeal with the sidefeed inlet manifold, which i hear is good.
all in all, i only see the appeal of one if looking at silly 600+hp power levels.as youll be taking advantage of ignition, sidefeed and thick block, other than that, seems more hassle than its worth on a BPU mr2.
sure the oem turbo on there spools very fast, but it also wont make the power a ct20b will.
swings and roundabouts.
the guy on the OC has hooked up an awesome engine monitoring program to it though, as its OBDII i think its called!

Besides over the seas there a few on standard internals running circa 400bhp.
It bolts straight up to the S54 and E153.
Makes more power than the gen 3(even with a smaller turbo), around the 260-270 mark.
Fuel cut is 19psi, actuator is 8psi and standard boost is 11.7psi.
Afaik the ecu still isn't mappable, but it is obd2
Getting hold of a manual ecu is difficult as they mostly came with the auto 4wd box, but the auto ecu runs perfectly once you have put the NSW to ground.
