Auto to manual

Even with new rods and pistons, lowered compression ratio and more boost, I would see it hard to get more than 250WHP without the engine becoming an uncontrollably peaky little thing. There unfortunately is no replacement for displacement.

But we'll see, there's just so many unknowns at the moment. I'm sure this engine has been modded to the extreme and then some in Japan, but how can we access that sort of information?

tis a good Q... I'd like to know myself what has been/can be done with the 1nz.

175+ whp can be done reliably on stock internals... right now all we can really look at is what the XB/XA guys have been doing.

Etimago= Looks like its all controlled simultaneously. I dont know if the ECU could possibly be re-mapped (isolating the auto controls) by someone who knows what theyre doing. Not too sure if the programming would stick though

I want to see it too, and if a turbo kit was around 2500 it would seem more realistic for the amount of horsepower... however, dropping 4500 for 175 or 200 hp?? I dont know, it just might be cheaper to do a full swap with new ECU, tranny, and built motor...
