Are the USDM 2jzgte's MAP and MAF meter'd? See the reason I ask is the SC300 w/2jzgte I am buying, the owner says I will need a MAP sensor to get it to run with the stock ecu.
The car currently has one or two bad coils and the stock MAP is broken, thats what he says.
Also my '92 MR2T runs an AFM and an internal MAP sensor!
Damn Supra Forums has been down for almost 2 days!

You will need to be able to work with this stuff or buy a USDM based harness. That's a pricey part, ($650-700 I think from Carson or Elmhurst), its very hard to come by a used one in good shape.
imho, a front clip of a jdm Supra would bring you a wealth of needed parts that you will end up needing. Radiator, SMIC, Ignitor, Power Steering Res, better sway bar, the bigger front brake calipers, rotors, oil pan in the right place, motor mounts and other parts you'll end up needing. Do not underestimate what that is worth to just have the freaking parts sitting there on that clip, a virtual parts bin. Some of them seem to come with the Getrag 6-speed that you can easily sell for $2500 if you stick with your five speed, better keep your rwhp in the low 400's or you'll need that Getrag, but thats another bunch of money, search is your friend.

But these are well known facts and have already been discussed quite a bit in other threads
The idea is to use a USDM wiring harness with the USDM parts (MAF + 550cc injectors), etc
plugs right into the JDM motor that way and wires up the same way a regular supra harness would into a SC300

with ODB2 I think they switched over to a different MAF sensor than what is on the 93.5-96s?

1) the MAF is an intake side air restriction
2) MAF's really don't do so well w/ BOVs that vent to atmo (it creates a rich condition on shifts)
3) MAP is used w/ aftermarket EMS solutions (A***s for example)
Because the sensor is typically mounted in the intake manifold, post turbo, it gives a more accurate reading of the actual airflow the engine is "seeing." MAP sensors also have the same resolution regardless of their maximum reading -- 3.5 bars or 5 bars.
I'm sure if someone like clint would care to chime in, he can speak in far more detail that I ever could... his dual MAF setup comes to mind.

Thanks for the input although I already know the "points" you pointed out. I guess I should have asked " does the 2jzgte run both a MAF and MAP when still on the stock ecu such as the MR2T does?"
I do appreciate everyones help and input though thank you,
Gregg
