My understanding is yes, but only if you have a JDM ECU. I may be wrong

 

Seriously, screw 100 octane. If you figure an addition 2.50 a gallon over 91, now I go through 12 gallons a week which is 30 bucks x 50 weeks....

Alcohol/water injection will pay for itself in just 6 months and you're still free to drive around. When I was on a 96 octane tune I'd always carry Torco in the trunk in case I had to roam away from where 100 was sold.

None of this rebuttal about "alky will blow up my engine". Well,
1. that pump is just as likely to fail as your fuel pump - which is not often
2. Whether you got 100 or do alky, if you're modding your car like that you should have the funds for a new motor anyways
3. It's more of the convenience factor of being able to fill up w/ 91 rather than drive to the 100 octane pump, and being able to drive cross country with just a few gallons of Safeway DI water onboard.

Besides, which normal driving I know of people who only fill up their WI tank once a month. DI water is what... pretty much free?

 

jdm ecu will advance timing ALOT with proper gas.

Its only illegal tosell at the pump if you are pumping leaded gas into a vehicle, container is perfectly legal.

 

I'm curious how the USDM ECU compensates for the 96 and 93 octanes available in the east coast & mid-west. Seems strange that the JDM ECU is the only one that compensates, which is expected, since they run 101-103 octane in Japan.

I wonder if there are California specific USDM ECUs which are different. I know for my MR2 SC there are USDM 49 state ECUs and there is a specific CA USDM version which is the only one that supports the EGT for emissions.

 

Like my comment with the JDM ECU that turned out to be right, I'm not sure about this, but I doubt there's a 49 state version of the WRX. I would have heard of this by now, and there'd be mention of it with respect to tuning.

If you lift your hood and check the emissions badge, should be able to tell if there is indeed a CARB version of the WRX....

Also, I think the 101-103 octane in Japan is Motor octane. Actually is 96 RON+MON/2

 

Last I heard... There was only jdm and us spec ecu's
<-- aw11 twincharged

 

Thanks for the clarification.

Hehe, always wanted to build one, just too much to spec/build/tune/maintain. Plus the HKS kit was unbelievably rare (only 5 made).

 

I agree with your opinion on this, I never suggested using this weekly. Hence, I suggested mix in my original post The original reason for the post was to find more locations and compare costs since there are people who put these in containers and take them to the track. I'd say auto-x but the runs aren't long enough to compensate for pre-det, since there is probably not enough heat generated. And most people know the 100 octane pumps at the track aren't the cheapest compared to these pumps available locally.

I don't want to turn this into a flame war of 100 octane vs alternative additives or fuel options, please don't misconstrue the post.

 

Great point Nicknaz, that's exactly what I do on my other cars after a track day. After putting in 100 octane or a mix of it you can also reset the ECU and it helps relearn the curve faster.

 

NO WAY! Twincharged aw11 is like my dream car - I'd take one of those over a C6 corvette, no joke I mean, not money wise but if I saw both for sale I'd take the mr2

You got specs and pics/info? Still got the car?

 

Check out this site has alot of great info

http://shell.deru.com/~sgn1/AW11/Mkimod.htm

It does not include Gerald San Agustine's original Twincharge AW11 from Toysport which was a beast. This was featured on SCC a while back- mid 90s.

I believe Mike C's twincharge was featured in the first SCC ultimate car shootout.

There are also AW11 1.5s which are 3SGTE (MR2 Turbo 91-95) engines in the AW11 chassis. Deno was the first to have this setup and is the pioneer.

Alot of MR2 info:

My car has been sitting in storage for the last 5 years. Total miles 68,400 miles.
I also own mr2online.com But since taken the site down unless you guys want to play with it.
I have a 3rd gen 3sgte for a swap at sometime. Just have to find the right donner car.

 

Yeah, I used to have '91T w/ a 3rd gen swap before I got my wrx. I always have a soft spot for the mkI. Surprisingly many mint condition MkI's I see driving around, the owners all love their cars.

 

Wow, nice!

Here's my weekend/lunch getter during it's better days.

Getting rid of this by the end of the year if you guys want to use it as a donor shell. It's a high comp 4AGZE bottom block with USDM head and intake manny for the CA smog.

 

another gas station is VP Racing gas station up in san leandro next to tapioca express/ san leandro bart station they sell 100 octane gas
