I like your screen name!!

 

I don't disagree. However, the ability to install nitrous and remove it without leaving anything obvious is up to the installer more so than the company that packages the parts. A custom install will always outshine some box of parts you're forced to choose from. Of course it will cost more, but that's worth it. Plenty of companies sell individual parts and you can piece together a stealth install yourself.

 

yeahh im deff glad to have this many people's opinions on it all.

and taking me serious is always nice but im more of a fun type of guy but cars is strictly bussiness. me and my buddy wanted to focus on a car that didnt get as much respect as it should when it comes to performance. we have the money to test a few is's and see which route would be best. we just wanted to see what everyone thought about if we could make your cars fast, realiable, and nice without any bs. yes, everyone knows money talks but were willing to do this and lose a few dollars if we have to. the standalone aem isnt gonna be a problem to work. take my word on that.

please keep the feedback coming, im all ears.

 

that's what a lot of others have said/promised, and look at where the state of the 2is tuning scene is. hasn't progressed very far since day one, has it?

"everyone knows money talks," but honestly, there aren't enough people in here that have the kind of cash to throw at something like this to make this remotely profitable (isn't that the whole point of being a business - to be profitable?), and even those that do are probably either in the stage of moving on or already have.

don't believe me? considering the uneven value perception that many 2is owners are afflicted with (read: lowball mentality - wanting and trying to get a filet mignon for the price of a hot dog wiener), and you'll get plenty to crawl out of the woodworks/under the rocks feeding you a lot of hype but not having enough digits in their bank accounts to back it up when it's ready to sell.

this is not to discourage you, but to give you a rough idea of the end result you may come upon if you continue down this road.

caveat venditor, fortuna secunda.

 

dont worry man, your not shooting me down. i totally understand what your saying. but this bussiness were doing isnt only focused on just is250's. were doing a bit of everything. my personal biggest part is importing cars and parts. we also have a good name with aem. but like u said, bussiness about making profit but im actually willing to spend more of my money just to see how we can get a is250 to run boosted realibly and over 7lbs.

 

Get it to run more than 265 at the the wheels (it's around 180ish stock I think) and do it with a kit that sells for less than $4000.

That you'd sell a lot of.

Anything else and it's cheaper to get a 350 instead.


That's why as little FI work as there has been on the 350 there's been pretty much none on the 250.

(except for the one guy who put a 350 LMS SC kit on his 250 because he lives in a country they don't sell the 350 in... and IIRC he was running a bit lean up top in doing so).


If it's much more than 4k (or makes less power than a 350 does stock) then you might sell a few of them to the uberhardcore that MUST have an antique clutch pedal in their cars... and you might sell a few of them to others in countries the 350 isn't available in... but that'll be about it.


I understand with 4 out of 5 2ISes being a 250 it seems like that's the better market for performance parts, but given how cheap a 350 is for a 50% power jump it doesn't really work out that way for expensive power adders.

 

You haven't actually done this yet, and you're confident you can build a standalone to interface with CAN and BEAN (an undocumented Toyota networking standard)?

I have a very good friend who knows engine management at a pretty granular level and codes embedded systems. He used to crack ECMs for APR. He wouldn't even consider taking this on and we've talked about it many times. You have a couple of million to burn on this before you see a dime in the door? That's what you'll need for the kind of development to make a plug and play standalone for the 2IS.

 

Couldnt you just take the pins out of the factory ecu for the engine and guages then put them in the stand alone? that way the factory ecu controls everything but the engine??? as long as the signals were the same

http://www.aemelectronics.com/engine...oller-f-ic-12/
or what about the aem fic? it claims to not mess with the canbus system



what did lance at toyomoto do when he swapped the 2jz in his car?

 

No, the ECM talks to CAN and BEAN to coordinate a bunch of different things. The FIC can be made to work, but it's a band-aid, not a substitute for fixing the maps in the OEM ECM (or building your own in a standalone.)

You'd have to ask Lance what he did. I really don't know, and wouldn't want to speculate.

 

And on to the other side of the fence, you have people that claim they can do this and that for the 2is crowd only to take money and have customers cars holed up in a warehouse a la turbochargers.com, remember him didnt that guy have some fanboys on this forum and what did the guy do screw people over and he was out lol.

 

I think the 250 kit would be good for over seas markets. I think there are countries that never got the 350 and the IS-F was like out of this world priced. I think in the US it's just plain smarter to just get a 350 and mod that if that's what was desired.

I'd be interested in a stroker kit for the 350 probably using a re-keyed 1GR crank?

 

yup. 1gr crank and rods. i will have lower comp pistons and forged rods soon as well

i have a piggyback that will work, but wont add timing just take it away, all of it if i wanted to.
and only change the maf signal, so fuel will only work to a certain point, then you get a cel and limp mode.

 

If I'm not mistaken, elite or whatever tried to piggyback the isf and said all they could do was get it to do the same thing you are talking about but was never talked about as far as they were successful with it or not. After doing further research and more reading, the AEM piggyback won't be able to do much because of the complexity of the ecu. I believe there are only two companies that really have any kind of tune for it. It is HKS with their f-con iS that comes with the supercharger kit and tom's racing tec II which both require JDM ecu's. Unless you are HKS350. You would think that there would be more companies in japan that could tune our cars. I think it's just too complicated and too much work that it's just not worth it to them. Well good luck on y'all's venture and hope y'all do figure something out and good luck again.

 

good research bud. and word on the streets is there's a reflash in the works.

 

which would be surprising given almost 20 years later nobody has managed to do that for the Supra- a platform there's a lot more mod enthusiasts for.

Here's a post mentioning some of the challenge with it BTW-
