What should I do?

[325Projectz]

Alright, more opinions needed!

Should I spend the money on 24/lbs injectors, 3.5 hfm, and a chip right now? I already have the lightweight flywheel to go with it. Anyone else done this & and what kind of power increase did you see?

Or should I just leave it stock?

[joshh]

I would think the chip will give you the best increase in power. But I don't know what you have done to the motor.

[325Projectz]

Stock s50. I don't have a AFM or injectors, so I figured why not upgrade right now.

I for sure need the chip for EWS.

Twin screw or ban.

HFM and M52 manifolds, get the air going a little better.

[325Projectz]

Hmmmm, good idea.

I'll add those to my list.

Do the m52 manifold bolt right on, or is there any modifying needed?

You need to have those extra two holes welded shut where some piping came out of the M52/S52 (something to do with OBD-II, I think), but yes, they're bolt on. They're longer though, almost touches the subframe, so you'd need a bit more custom work if you already have your exhaust set up for an M50. In Sean's case, he won't have to worry about anything because he has no exhaust yet.

You can also get the exhaust gaskets that cover 3 exhaust ports (so you need two). I heard those work better than the stock ones.

TEC3r thats what you need. :D

haha- or ms for 1/1,000,000 of the price... either one will work.

[325Projectz]

No standalone right now.

Order HFM, injectors & chip.

[NickP]

you also have the option to disable EWS

[325Projectz]

The TMS chip will take care of that.
