Yeah everybody keeps telling me it's not worth the hassle. However I already made the set-up up, so I'll be trying it this spring.

Might be awhile, I'm not building it untill 50k. I hope to have all the parts ready to go by then. I wish we could get an aftermarket tranny for our car.

i think you can modify them up to 850cc, but then again that would have no pourpose for us.

Any body have an idea of what you should pay for a set of WRX injectors? Seems like a pretty good way to go. With 440cc, 255 Walboro, and a Dsm afc.

Just to add, I was asking my friend about why STi injectors drop into a WRX but supposedly not an MSP, and he said that the STi injectors that the WRX people get are from the jspec sti, which has the ej20. Maybe jspec STi injectors would drop in?

They usually sell for about $150 a set of four

That is correct. The USDM STi Injectors are side feed 550s. The JSPEC are 550 top feed. The MSP needs top feed injectors, so USDM STi injectors wont work.
However, WRX injectors will drop right in. Throw on a walbro, and youve got plenty of fuel for 150 bucks.

Which it wont. You'd need an emanage, or dsm afc for this to work. However, adding in a walbro 255 would be fine.
