Hello Again! I just wanted to let people know what I think about the swap so far. I got it on the road and its runs cool, great oil pressure and seems to really like being in the MR2. I can't think of having this motor in a much heavier car really!

So in my experiences so far I would sum up a 20V MR2 as "elegant"
Why such a word? The motor responds to every little input smoothly. Its almost as if your dancing with the motor. The C56 Tranny is really an upgrade, I can feel it shifts better and smoother. Just FYI I automaticly rev-match down and granny shift up which eats clutches but saves the breaks for when they matter. I can shift at almost ANY rpm and this motor/tranny takes it as if it didn't matter.

The motor revs really quickly, but smoothly. It even revs down smoothly, this makes it very easy to efficiently use the motors power and leaves more attention for turning and break balancing. It pushes my little MR2 in any gear, even 5th. OH and another thing, and I LOVE THIS PART, the more throttle you give this motor, the more power it puts down. There is no lag, you want faster, you push harder. The old 16V 4AGE pretty made you shift down... the power band seems much wider. I don't know if its the VVT or the black-top ECU I'm running, but its nice.

Talking about Blacktop ECU, the motor revs to 8400rpm, pulling the whole way in 1st, 2nd and 3rd. It gives you that extra little top end in the ever-fun 3rd gear that superises a lot of people. Not to mention shifting that the higher RPM dumps you right in the middle of the next gear's power band as well. The ONLY draw back I see right now (and I haven't even run a full tank yet) is it seems to dump a little more fuel into the engine. That might be the extra 800rpm talking though.

I did run into one problem though, the top end towards the front sounds a little loud... is this normal running a BT ecu? I'm thinking of doing an oil change since I'm kind of re-breaking it in. Its not chatting but it sounds a little like a desiel I do have a horrendisly warn out distributor cap that I am replacing on Monday plus a set of plugs coming in... so we'll see. If it comes down to it I might run a little lucus in the mix.
