Picking up HKS top mount w/t25 and lines for $300!

Here is my seat leg rubber cap mod. LOL All I did was poke a hole in the middle, cut it in half with scissors, cut in a "grove" so the sheet metal will have a edge to grab, then jam it in. This fits perfectly for a temporary AC line plug on the firewall if anyone was wondering.
I zip tied the wideband wire
I'm actually not set on how I want to wire this stuff. Behind the seat might not be the best place. Just trying it out for now but I'm having wiring issues anyways. :(

Won't work well. Cranking the fuel pressure on NB injectors apparently works for really low boost. But no point at all if you already have a MS. Just buy some RX8 injectors or something.

Yeah through the shifter sounds like a great idea! It's at the transmission tunnel hole where the stock second O2 sensor was.
I saw how cheap the rx8 injectors are and so they are on my list for future upgrades but I want to run my free oem injectors lol

Blowing up an engine because of a lean condition is a lot more expensive than injectors...

Based on a statement made in this thread sr20 turbos are good for about 10whp per psi. Stock VVT engine is 142hp. So 7psi * 10 + 142hp = 212. But since you don't have the best flowing stuff lets say a round 200.
Calculate the required cc of injectors needed (from the wiki):
200 x .55 / 4 x .8 = 110 / 3.2 = 34.4 lb/hr x 10.5 = 360cc
So you need 360cc injectors.
Stock NB2 injectors are 265cc at 60psi (Because you aren't using an Adjustable FPR, just don't) so:
60 / 43.5 = 1.379
sqrt of 1.379 = 1.174
1.174 x 265cc = 311cc
So without any fuel management you are about 49cc's short...
These are pretty common on the islands right?
Yeah, you're one of those short.

Maybe I do need injectors..

Stock MSM is rated for 178hp. FM tested it and found that it was at 5psi.

I'm out. Just realize that running out of fuel is what blows **** up. Leaning out causes detonation, which breaks things. The last thing you want to do is spend 2k on a rebuild, which is 10 times more than injectors.
