On a side note, with a Big16G you should have been able to make much more power. I had a DSM for 3 years and some of my buddies with the B16g were making close to 300 FWHP (disconnected centre diff) on an otherwise stock 2.0L engine. Looks like you had some airflow restrictions.

Agreed. We aren't going to see much over 200 lb/ft of torque (if it even gets there) with this motor in a stock configuration. The good news is that you can run a small turbo that will spool well and it wont fall off on the top end like the chart above.

Hear hear! I think you might get to 200ft-lbs, but you wouldn't stay there for too long.

A small conventional bearing turbo (e.g. T-25) or medium sized ball-bearing (GT-25R!!

well maybe a bit big) would probably be best for this engine. Quick spool is what we need really.

Does anyone know why Toyota is so adamant about using the F series engines? I mean, there are so many limitations about the F series heads from a NA standpoint (unless you got lotsa $$$) that it seems to put Toyota in the lowest level as far as engine performance goes.

I've always found that torque is the main enemy of a FF if it springs to early, being able to have a broader powerband with a high HP low torque motor seems to perform the best overall. Guess I just don't understand why Toyota doesn't want performance motors when the 4a-g motor was so popular, and even that wasn't the most Uber, but it did have amazing qualities.

I guess I really like the Vitz, but I'm really dissapointed with the motor so far, seems like the Fit has much more potential, especially from a NA standpoint.

It is built as an economy car. Toyota does not care about power.

I'm asking about all of their engines. Apparently, even the car that Toyota has marketed as a M3 fighter, still uses a F series engine. If they ever came out with a new Supra, they'd probably still use a F series engine. Toyota seems to be the new Oldsmobile, they had their hey day, but now all they've got is economy. If they came out with a sport Yaris, it'd probably just have a lip kit and fog lights. I just don't understand why they are so obsessed with F series motors. Isn't there supposed to be a trickle down effect with their racing in F1? I'm just not understanding why there has to be no real "performance" engines in the Toyota lineup. With the Celica GT-s gone, what real performer is there engine wise? F series motors are not my cup of tea I guess. I love their cars (family has always been since the 70's) and I've driven my share of their performance cars over the years, but I am just very dissappointed with their performance division, and with the "F" type Lexi coming out to compete with BMW and Benz, what are they going to do for the Toyota name brand? I like Lexus and all, but I still don't hold that appreciation for "Lexus". That means luxury to me, but I would rather have the circle with a T in it instead of an L.
