ATX TT owners post up.

[lDoomZdaYl]

with fuel controller i should be able to max out the 9b's since you cant do that with 360cc. And the Turbo ECU i dont think that ill need since im going to use bigger injectors which need fuel controller anyway.

[maTT]

jomojr has run 17psi on race gas with 9b's and 360 injectors. I would NOT do one of these conversions without the TT ecu, but that's just me.

I'm converting my sohc atx to dohc tt atx as we speak. This will be my 3rd atx tt conversion.

FWHP on 9b's will be around 225.

[inperfectdarkness]

^ WITHOUT a tt ecu on 8:1 compression.

hey maTT....when you get finished with that swap; could you post what differences and cost there is between the DOHC > TT and the SOHC > DOHC TT there is?

WhiteSmokeRacing pussified out on me doing something like this, and i'm curious.

thanks!

What fuel controller are you going to use?

The problem with running 450cc injectors is that your timing is going to be through the roof with an NA ECU. While you are driving off-boost, your pulse width is going to be extremely low and your ECU will advance timing (a lot).

When I started my TT/ATX conversion, I also convinced myself that I could use the NA ECU. My tune ended up being richer than I would have liked due to low throttle timing-induced knock. Now, I am in the process of installing a TT ECU and fan controller. I recommend you do the same (unless you get an AEM ).

Also, regardless of fuel you are not going to be able to max out the 9bs without serious knock prevention. Assuming it is a street-driven car, meth, toulene, or alcohol injection is probably the way to go. IPO used to sell propane kits too, which some people swear by. (maTT, does 3sx sell those kits now?)

Race gas is good, but not practical for street driving.

If you're set on larger injectors just go ahead and get 13g's or 15g's. Forget about the 9b's.

Also you won't be able to go any larger than 525cc injectors on the stock ecu with a fuel controller.

[inperfectdarkness]

since when can't you max out 9b's on 360's? 9b's are only good to about 14psi (no meth, on pump).

There is no reason not to run a turbo ecu. It will make your life easier cause it has a base to for turbos unlike the na ecu. No reason to risk running lean or rich if you don't have to.
