Going to push a different direction with our car for now Options

[Fastbird]

It's been a while, but it's time to make some changes to the setup of our swapped car. Remember that with a SMT6 piggyback and some other work, the stock CT26 made 249 HP and about 260 TQ to the wheels in Summer of 06. Over the winter I noticed that the CT26 will actually put out 18-20 PSI and HOLD IT TO REDLINE with good enough air.

So here's what I'm thinking (and it will all happen relatively soon):

AEM EMS for complete tunability w/GM IAT and 3 Bar MAP (AEM or GM).
Water/Alky Injection full time, boost referenced and tuned accordingly.
AFM Delete in favor of a better intake tract.

I figure by cooling the intake charge via the Methanol, the boost should hold on a little longer. I'm curious to see how much farther I can push the Ct26..........

There's a dyno shop here in IL about 15 minutes from me that is reasonably priced that I will be frequenting.

Thoughts? I'm sticking with the stock injectors for now as the meth injection will be partially like an added fuel also as well as a cooling tool.

I will not be upgrading the turbo first as I want complete engine control above all. I'm above the mindset of tuning capability above all else at this point.

I still feel that with a more accurate tuning ability and a shot of meth with a little additional timing (as allowed by the meth) a decent gain can be seen at the 16 PSI level I'm sittin gat right now. I never said I was going to push the CT26 to 18-20 PSI, only noted that with good air it will hit and hold it as I found out last winter in Jersey. How close to that good air I can get will make that 16 PSI I have it set for that much more efficient.

Once this little endeavour is done, then I'll move to a bigger turbo, injectors, rail, and peripherals.

man your stubborn.lol


listen.... i have meth injection on my car, as well as a wideband, an safc for tuning, and a way to monitor knock. so ive already been down the road you plan to take. i can tell you that the ct26 at 17-20psi WILL blow your motor, even with meth injection. the fact that your knock sensor already blew is a clear sign that your pushing the stock turbo too much.

getting a stand alone is always a great idea, but you have to realize that is NOT where the bottleneck of the 3s exists. the jdm ecu has some pretty agressiving tiing advance in the stock fuel maps. there really is not a lot to be gained with a different tune. youll end up spending about 2grand for the stand alone (at least 500$ to pay a tuner just to get the car running normally), and in the end, you will maybe gain 10hp over what you have now, and the power band will still fall off at the top because of the ct26.

a smarter investment would be to spend 1900$ on a gt28rs kit. its a great turbo. on stock injectors youll make about 280hp/tq...and then when you buy the aem and throw bigger injectors in there, youll be able to crank the boost up even more and hit 300-350hp. youll never get that out of the ct26.
