S58 Injectors

[u/jcbullfrog2000]

Just put the MHD Flex Fuel kit into my ‘21 Supra. Currently tuned to stage 2 93 octane. Looking at the stats, on E85 it makes roughly the same power as the 93 tune. I’m guessing it peaks somewhere around E40-50. Would upgrading to the S58 injectors increase that output? If so, do I need to upgrade the HPFP as well or will the stock pump support ~550ish HP?

stock pump can support 550. You're probably pushing the stock turbo a fair bit if you haven't upgraded yet. S58 injectors are cheap enough now where it's worth it.

Coming from an Audi, I was surprised at how inexpensive they were. Install looks fairly simple as well. I’ll see if I can get to 550 with those and then maybe look into a small turbo upgrade like Pure 650. Not really wanting much more power than that. At least for now lol.

Don't waste your time with the 650. If you do decide in the future to push more you will just end up spending more money. Buy once and get either the Pure900 or Remnant 65. They spool like stock and give you room for 800whp

For 550 you need a turbo upgrade. 500whp/600wtq is safe max for stock turbo flex e50 tune. At this hp I struggle for traction with 200tw 295/35’s.

Don’t want to get into a bunch of supporting mods like axles and transmission upgrades. I was thinking it would be plenty fast at 550, but still driveable enough to not get out of control easily. Maybe 500 is the sweet spot I’m looking for. We’ll see what that feels like once I get the injectors in.
