lol! likewise

 

Good luck. I think, I will add turbo when the engine guarantee was off.

 

from my exp. in the automotive world, electronics of all kinds send 2 things to and from each other. 1's and 0's. no electronics speak Japanese let alone any other language.

 

what about changing the pistons and rods to lower compression ratio like what they are doing to the IS-F right now?

 

It has previously been explained that the pistons in the 2IS have a very specific shape in order to manage the stratified lean charge for the direct injection system... so it would require either quite a bit of very expensive trial and error, or some fundamental engineering knowledge of the original design, to create aftermarket pistons that worked properly in the engine while also lowering the compression ratio.


This regardless of the fact that by the time you're replacing internals like that it would end up being cheaper to just buy the faster version of the IS (350 in case of a 250 owner, F in the case of a 350 owner)

(and all of the above assumes that lowering the compression doesn't then just run you into another barrier like running out of fuel, ECU limitations, the thin cylinder walls, etc)

 

you should watch the is-f build from elite. Correct me if I'm wrong but the is-f engine has the same bore and stroke of the is350, so the exact pistons they have developed for the is-f should work well in the is350.

The jury is still out on how it will work though. In the pictures it seems as though they tried to keep the dish shape some, so who knows.

 

IS-F motor is a 2UR-GSE, bore and stroke are 3.70 in x 3.52

IS350 motor is 2GR-FSE, bore and stroke are 3.70 × 3.27

 

i remember Elite mentioned something about they will fit on IS350...

 

No, I mentioned they might. Unfortunately it might not be true. The piston for the IS350 fits the GS350 and the GS450h, not the IS-F. I had hoped for something different.

 

well poop...

 

I really wonder what the piston dish looks like, has anyone seen it? Toyota could just be blowing smoke up our asses...

 

^^That's a very bold statement. I highly doubt that Toyota is blowing smoke up our asses.

 

I don't know, just saying they could say it's very special when it's just a bit different and no one wants to duplicate it because it's pointless (for other engines) and no one knows what it looks like so no one knows if it's possible to just run a different type of piston etc, etc.

Tons of car manufactures will always claim they have the next best tech when sometimes it's nothing special.

In any case, I'll go down the road of turboing my car when time/money permits.
