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??

 

Uh oh.
*waits for the IS350 guys to come rushing in to tell you to get the IS350 because it's the easiest and cheapest way by far*

seriously.

 

Yep unless you got a manual and you want more power out of it just cause it's a manual lol

 

oh well my company pays for this car i get to keep it so... cant complain, just gotta work my way around the fact its a 250

 

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.

 

My personal favorite is when we IS350 guys suggest the IS-F lol!

 

what a useless thread LOL don't mean to crap on it though.. the isx50 is no sports car.. the is-f is a sports car...

 

He's new, give him some slack.

 

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

 

yea man go get an IS-F

 

I'm gonna start a new trend.

Get a Veyron...it has 4 turbos.

 

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.

 

2jz ftw!!!!!!!!!!

 

Is that same supercharger one can get for $17,563.63 from here?


Looks like a whole 50HP for $17K. Wow!

or I can get 50HP from this.
Hey...I believe it.

or I can add the price of that $17K supercharger to the cost of an IS250 and get Cayman, Corvette, Lotus Elise, etc, etc.........
