Just wondering if anyone knew if or when the IS250 would get the D4-S injection like the IS350 has?

It will never happen, just like virtually all other manufacturer hasn't done it either, and are suffering from carbon build up.

The 2GR-FSE is a fantastic engine. No wonder it was engine of the year when it came out.

I would venture to say never also.

Funny you mention this...seems like the manufacturer and dealers are waiting to make some money with the decarbonization of all these engines that are out there. I notice this too with all the other Direct Injection engines....

Isn't Toyota using D4-S in the new GT-86 (Scion FR-S)??? If so, I wouldn't be surprised if that makes it's way into an IS250.

TimboIS

That is true, but it's a Subaru sourced engine I believe.

Most of Toyota's DI engines use D4-S, the 4GR-FSE in the IS250 is the only engine they sell in North America with D4 and not D4-S. (The 3GR-FSE was also only D4, but it was only used here for a couple of years).

D4-S is currently Toyota is doing DI in newly developed engines. The 4GR-FSE hasn't gotten it yet, and I doubt it will, but who knows. Maybe if they keep using the 4GR in the 3IS they'll change it, but in the 4GS, the 4GR-FSE is still D4 only, not D4-S.
