rpf1s are exceptionally light, ESPECIALLY for the money. you can bet those oem 17x7s (with the lengths theyve been to to reduce weight on this thing, id be surprised if they were more than 16lbs) are lighter than most of the sub $1500 aftermarket, and for sure any rota, which seems to be about 80% of the wheel market these days.

yup, thank god for you early adopters for letting teh rest of us sit back and wait for prices to drop :happy0180:

what causes problems in first gens is new technologies being introduced, such as the high pressure fuel pumps used in the bmw N54, limping all sorts of X35s. both subaru and toyota have a good record in this respect, but i also havent seen a lot of vastly different technologies introduced, besides cam phasing, which afaik went well for both. the only thing i look at is the parallel fuel injection system, and that mostly cause i come from the subaru camp so dont really know toyotas history with it, ie how different this is from previous versions (has toyota released cars with BOTH direct injection and port injection? SEE EDIT BELOW). subaru purportedly did the majority of the engine development, but im sure in this respect got all the help they asked for from toyota. however, i could see this being a problem in the STi version, depending on how aggressive they get, as i am beginning to think after release of these base models the collaboration between teh OEMs will dwindle.
EDIT finally some of my poking around paid off on the matter and found history on this D4-S system

Using direct injection and port injection simultaneously facilitates more precise mixing of air and fuel under low and medium load conditions for greater efficiency, while high load conditions dictate the use of direct injection alone for maximum power. The 2GR-FSE engine is rated at 309 PS (227 kW; 305 hp) at 6,400 RPM and 38.4 kg·m (377 N·m; 278 ft·lbf) at 4,800 RPM. The engine's service weight is 174 kg.
The 2GR-FSE was on the Ward's 10 Best Engines list for 2006, 2007, 2008 and 2009. |
id say that last bit is a pretty strong indication of a good, solid system
that would eliminate any fears i would have regarding early adoption, although this engine will be mixing subaru's AVCS with the D4-S, which is a first (wonder why AVCS over VVTi?). but still, that seems to suggest most potential problems would be integration/control/ecu related. but personally ill wait to see what the STi/TRD look like as im nominally cross shopping with cayman, lotus; but would definitely prefer to see some NA performance versions, even at the expense of peak power.
