Been looking around and doing some research but there dosent seem to be any info out there on how to do any form of forced induction on the is250.
Apparently ecu is the hold up anyone hear of anyways to get more then 6-7 psi into this motor??
The ECU has nothing to do with it.
The fact it's a 2.5L engine with 12:1 compression has a lot to do with it.
There is, literally, nothing reasonable that can be done to make an IS250 significantly faster.
If you're really feeling game you can try nitrous, a couple folks have had decent luck with it on a 350 anyway to add about 50-60 hp on pump gas. But you're simply wasting your time if you want to get anywhere near even the stock hp of an IS350, let alone more.
hahaha i know i know but i can't help but say somethign when i see a thread like this over and over again. i just hada make a comment ONCE on this subject lol
No ECU software, no more higher boost #'s ... Sigh
Seriously, the ECU has nothing to do with it. 12:1 compression does.
TOMs has ECU software in Japan. Their supercharger kit makes 10 more horsepower than the stock-ECU one in the US. And that's on higher octane gasoline too.
