I'm looking ahead at the dif. options i want to explore with this car.

It currently has a 14b and i'm wondering if i should push it, or if i should just go ahead and upgrade when i get the supporting mods done.

granted teh ic i bought is large enough that i don't have to worry about much cooling, but i was also considering h2o/methanol injection to keep the knock low and also 550's w/ a 255 lph fuel pump and dsmlink, not to mention hard pipes.

didn't kno if this was a feasible goal or if there was something else i might have needed or what.

anyways any input is appreciated.

With a 255 lph pump look into an AFPR like the FTS kit, which is pretty cheap (275 w/o a gauge). If you're going to get DSMLink I'd suggest getting larger injectors, probably the 880's or 1000cc ones since those seem to be popular. I recall there being a problem with the 1600cc ones people were using. This all depends on how far you plan on taking the car, but I'm starting to wonder if I should be going up to 1000cc injectors if/when I upgrade again.

Turbo-wise, you could upgrade if you want to but you won't get pronounced effects with certain mods (less with cams than bigger turbos, and definitely less to none with a SMIM).

push it to the limits with that 14b, it wont hold much but you never know you might of gotten a sick infested BOOSTED 14b *shurgs*
and then save up and start watching for a good priced true EVO 16g to slap in there.
you got a fmic i saw in another post right? Yea....your on the right track.


batman

1000cc?! wtf man!?!?!

that's a little oversized even for my longterm goals which may or may not include a holset setup.

upgrading would mean for me 660's and a used 18g or evo3 16g (not GT)

but hey, these things will be sitting in my closet until they all go on at once later in january or over spring break even.

Hell I'll sell/trade you my Denso 660's if we both decide to upgrade. The reason I suggested the liter injectors was because I'm slowly seeing that any mid sized turbo basically requires 880+ injectors--660's will only flow 3.756 lbs/min of fuel at 85% IDC on 93. Needless to say even some Evo setups can outflow that, even with a lean(er) AFR, not to mention losses through the lines, pressure drops, etc. If you're looking at anything beyond an Evo III definitely upgrade, especially with DSMLink.

if we both decide to upgrade, i can live with that. hard to believe that 660's are that inefficient though, and i've been looking at an evo3 or 18g setup. mildly modified, prolly not more than 20lbs of boost and perhaps some methanol injection to keep the knock low.

hopefully, between it all 660s will be sufficient. i've been told that 550's are perfect for any evo3 setup... lies alll lies

It depends more on airflow than boost pressure--boost pressure will only change your choice of fuel pumps really. With the amount of airflow an Evo III is actually capable of pushing out (44+ lbs/min, proven by very few people but obviously a real number) 660's may be inefficient. For the rest of us Joe Schmoes only flowing a measly 35 lbs/min airflow the 660's are fine. I'm stuck with a boost leak somewhere that I haven't tested for yet, so while sitting at ~18 psi boost I only saw about 75-80% IDC on the stock "tune" (meaning like a 10:1 AFR).

The devils are in the details. Let me know if you need any other advice, I have a lot of time.

glad you do ! car is still in pieces though, so as soon as it is going, and paid for, i'll work on modding it more
