Alright guys, I am going to try to add turbo to my car. I will let u guys know how it goes.

 

good luck!

 

you made a custom turbo manifold? GL!

 

yeah goodluck i want to do it but i dont want my car to turn into an unreliable peace of crap, not to blight your idea, just be careful and hope for the best, im keeping my fingers crossed for you!

 

You should of been 1/4 into your turbo making plans so you can tell us whats up..not tell us you are going to start. Too much anticipation!!!!!!

 

what are you planning to use for engine management?

 

will be interesting to see the gains.

yeah thats the thing with turbos....ya never know ..if ya gonna blow it up..
stinks ...

 

the shop and I are both going to start tomorrow. We are going to use trial and error.

 

you rock.

I'm hoping for the best

 

I'm not sure I'd want to use trial and error on my $10,000 engine...

There's no engine management possible on a US spec 2IS. The stock programming is conservative enough to run around 5 or so lbs of boost with the normal O2 feedback...and with a 12:1 compression ratio it's not going to be safe to run much more than that unless you're also adding alky/meth injection or something.

In the end you're going to spend 2-3 times more than you could've just traded in for an IS350 for, and end up with less power (assuming they don't blow your motor with too much boost)

There's a -reason- nobody makes a kit to do this

 

Best of luck to you! I'm not trying to rain on your parade but you might want to look into potential problems with the ECU reprogramming.

$10,000?!?! Thats if you buy brand new maybe, try ebay dude. $4500 right now.

 

My car was new, I'd sure want my engine to be too.

The only used engines for a 2IS you're likely to find on ebay will be from a wrecked car...might be fine, might not, still won't be what came in it from the factory, so that'll ding your resale pretty badly.

And $4500 is roughly the 250->350 price difference for that matter...so turboing a 250 to make maybe 40-50 extra hp over stock, which is still gonna cost you more than that in parts and labor if you get lucky and do NOT blow the motor... still makes zero sense compared to gaining over 100 hp with a full factory warranty in a 350.

 

We got a used greddy turbo from a 2006 scion tc. We also brought a used spec ls intercooler system. I brought all of them for $ 2,000. From there on my shop will try to put those stuff together. We order a new ecu chip from tom's and reflash it. My shop guarantee that the turbo will work! lets see

 

Is your car a US vehicle, or a JDM vehicle?

because the TOMs ecu doesn't work on US cars.

Says so right on their website (though it does so in Japanese)


I have no doubt it's possible to make a turbo "work" on your car.

Work properly, safely, and producing enough boost to add more than maybe 40-50 horsepower? Not as likely.
