Default Stock Rev Limiter

i have a '93 impreza 1.8 and i'm going turbo on my stock ecu, i was woundering how can i move my rev limiter from 6000rpm to at least 6500rpm either using my stock ecu or any other subaru ecu that will fit with out to much work being done to my harness? btw i'm running a stock wrx turbo, 380cc injectors, 3" catless downpipe and catback, catless uppipe, 255lph fuel pump, and fmic, 1.8 sohc heads, and ej18 block.

If you're doing all of that you will have to get a protune, and your tuner can change the rev limiter.

I think Storm was able to trick the ecu into reving higher.

I was looking for the same info, how much do you think this would cost, and can any piggybacks like the e manage raise the limit?

Is "protune" a brand or what? What tuner do you know of that can tune with a '93 ECU?

No, piggybacks cannot raise the rev limiter. (At least, I have yet to see one that can.)

Yes. There's a guy that advertises in the back of GRM magazine to re-clock your ECU. I got his number from Jay Storm and sent him a spare 2.5GT ECU to be re-clocked. He raises the rev limit in %s, so I went with 10% to give me a 7150rpm rev limit. I haven't tested to see how high I can actually rev the engine yet, but I do know it will rev beyond the factory rev limiter.

Another thing to mention is that clocking your ECU will not change your timing or fueling maps. The Ej18 has really agressive timing for running a turbo. And getting the right fuel trim is a bit of a challenge. If it's good at idle, it goes lean up top or vice versa. You can work it out, but it takes some skill. Or a standalone. Maybe you can pick up a "Protune" for cheap on Ebay.
