Title: 2.5 Build Questions
Post by: Bear on March 07, 2011, 07:21:36 PM: I'm planning on doing some bolt-ons ofn my '00 TJ (Auto).. I'm looking for you guys to look over my list to see if my ideas are correct.

Some of the parts below I already have sitting around the garage.

- 4.0L Throttle Body
- 24lb Ford (Fox Mustang) Injectors
- Cold Air Intake
- MSD 6AL Box
- E3 Spark Plugs
- Taylor 10.4mm Wires
- Banks Monster Catback (2.5" Stainless)
- MSD Coil
- Electric Fan (Radiator)
- High Flow Cat
- Royal Purple Oil

What do you think.. I feel like I'm missing something.

injectors will flow 25.5 at 49psi (the pressure your Jeep is running at), that would be about 10% more than stock, that would put you in the low 12s for afr, not sure if you want to go that low - just a heads-up.

What do the stockers in the 2.5 flow?

Go with Champion Platinums (3034)
They will last longer, and have the same heat range as OE.

i meant that would be a little too much fuel (i referred to afr when i said low). 32lb/hr would be out of the question, so if you really want to do it 24 is a better choice.

stock injectors flow 23.2 at 49 psi.

32# injectors will flow 34 lb/hr at 49 psi, so that's 46% increase, waaay too much fuel.

The PD kit comes with great wires. I'd do that over the MSD stuff.

I already have the 24lb Ford Injectors, MSD 6AL Box, E3 Spark Plugs, Taylor 10.4mm Wires, Banks Monster Catback (2.5" Stainless), Electric Fan & Royal Purple Oil sitting in the garage. I'll have to use it for now to keep costs down.
