2G Safe To Drive To Shop With E3 16G & Stock Tune?

[JackStieben]

Hey guys, still somewhat of a DSM newb. I'm upgrading my T25 turbo in my '97 gst to an evo3 16g. I have these supporting mods:

• Punishment Racing FMIC
• Greddy RS BOV - recirculated
• APEXi GT downpipe
• APEXi N1 turbo-back exhaust
• STM air intake w/ MAF
• Hallman ES boost controller
• fuelab AFPR w/ gauge
• wally 255 pump
• EVO IX 560cc injectors
• AEM UEGO Wideband
• Autometer z series boost gauge

I'm going to use a 1998 gst blackbox ecu and get it flashed until I can afford dsmlink. I plan on taking the car to my local shop who recommended me the blackbox ecu. I'm wondering if it'll be safe to drive my car to the shop? It's about 20 minutes away and the fastest the roads I'll be taking is up to 45mph. I was also considering renting a flatbed trailer from uhaul and using that to take it over to the shop? I don't feel comfortable flashing myself because this is all very new to me and this is my only car.

TL;DR What is the best way to transport my car to the shop with all my upgrades in and the stock ecu.

Just stay out of boost.

Dial in the injectors or put the stock 450's back in to be safe. You can set the boost to 10 lbs and be fine (with stock injectors), but I wouldn't drive with any injector larger than a 450 without a tune.

Don't drive the car anywhere with those 560 injectors on the stock ECU. Leave the 450's in and change them when you get there.

If you dont want to remove the 560 injectors, how about lowering the fuel pressure (since its adjustable) to temporarily compensate.. I wouldnt know what value target fuel pressure though

 

[jared98gst]

Don't turn the pressure that low on stock ecu no other tuning, put 450s back in drive it at wastgate pressure, nothing gonna happen, nothin to worry about

 

[JackStieben]

Okay, I'll temporarily swap out the injectors. But will I be able to start the car and add coolant and such with the 560s in? I also changed the head gasket and timing belt/accessories so I don't have any coolant in right now.

 

[jared98gst]

20% more fuel it might start but I wouldn't its just fuel rail bolts I'd swap em since your swapping anyways,

It'll be fine with stock injectors, don't run larger without a tune though as others said. I ran my 20g for a little while on stock injectors at wg pressure without issue. My injectors were about maxed at wot though. But you'll be fine, just like the others said, swap the stock injectors back in run the turbo at wg pressure and drive it over there.

You can start the car with the 560's in, but your car will run very rich and you'll likely end up with gas in your oil.

It would be a bad idea, you can ruin cylinder walls that way, and possibly even bearings if enough got into the oil
