yes, a fmic should be one of your first mods. dont bother with a turbo until you have reworked your fuel system. otherwise you will just end up having more lag and less power.

thanks. i dont know if you checked those links or not, but if you did, are either one of those kits suitable for the sr20det? i do plan on upgrading the fuel system as well. from what others have helped me with and what i have read up on, i understand i need to do the following:

1. walbro fuel pump2. 740cc injectors3.apexi safcII4.z32 maf

is this correct? am i missing anything, or is all necessary? thanks alot

yes, that's it. if you are asking whether or not they will work, then yes they will. you might have some slight misalignments of the pipes, but nothing major.

if it were me, i would spend a few extra hundred bucks and get a quality greddy fmic, not some cheap ebay knockoff. in general those things almost always end up causing problems. you get what you pay for... just my 2 cents.

Other guys correct me if im wrong, but if you plan on running the 740's you are going to either get a PFC or get a tuned ECU for those injectors. I think the SAFC II will only allow you to tune up to 550's. But you can get a tuned ECU for 550's and then the SAFC II will allow you to tune for 740's. Its all about percentages.

you are correct. with STOCK ecu you cannot control the fuel with 740cc... SAFC2 could only regulate up to 50% above your currect ecu setting so.. 370 divide by 2 = 185. ADD everything up 370+185 = 555cc.... the most you wuold get from stock ecu with SAFC2 is 555cc. Thus, you would need a tuned ecu, PFC, or any other aftermarket managements (ie: ems, greddy ultimate) just ask you stated.

well depends on your turbo of course. what kinda power do you WANT to to making? if you're going for high power of course 550s are not suitable... 300whp is probably good for 550s. PFC = Apex Power FC ... its an engine management system

almost any inner cooler will work, you jsut have to have the piping to make it fit.

jsut remember, the larger the better it will cool but you will have more lag.

the ebay inner coolers are fine but a little large from what i remember.

search around and read up on some of the members set ups.

for you to go MAPs on PFC you would need to buy the djetro kit for it. it comes with everything you need to get rid of your maf so you will not to get anything outta no donor car. The thing with PFC is that you will need yourself a pro tuner if you cant tune it yourself (i wouldn't recommend tuning yourself unless you have experience) The tuner should be able to get everything done for you.

well 550's are the largest injectors that you can tune w/ a safc II on a stock ecu. And pfc means APEXI (power fc).Also running 550's with an upgraded turbo, such as a GT2871R I would'nt push past about 15-18#s. A good ECU tune would allow you to run more boost because it would adjust timing according to your set up and specifications. All you do is tell them your set up. I would suggest enalthapy or JIM WOLF.Although I have found JWT seems to be a little to conservative making the car run a little to rich, but adjustable w/ your piggyback. I would also highly reccomend a wideband to add to your list.

thanks alot guys, i have some better understanding now. i know i will definately need an expert tuner-i have never done it before, and as you all can see, i really dont have a good understanding of it. i WOULD LIKE to have a setup suitable so in my future mods i can go up to 400whp. so, can a few of you give me an exact setup list for reaching this goal(fuel system-wise and turbo, if you can). i sure do thank all of you for your much needed help and patience and i will continue using the magic red button to lookup others setups oh yea- does anyone know(if at all existing) where i can get a good set of either injectors for a fairly low price-i havent even found 550s for under 300-thanks again!

do you all think this is a good buy?

srpwr: so does that mean i can use these injectors, stock ecu and safc2 tune; and later on get an ecu tune for more boost/hp?

Yes sir. just dont get boost happy. Have you decided which turbo you are going with? Remember... No matter how good your fuel system is, a stock turbo can only take about 14#s. T25 that is.

Which T28? Yes, you will definatly need a walbro and a FPR, a NISMO unit will work just fine. You will also need a boost controller for runnning more boost. I suggest a manuel one. you can look one www.boostcontroller.com and they have some good ones to check out. Oh yea, you are going to have to get a topfeed fuel rail. The cheapest I have found a new one is at www.jgycustoms.com.

it is the one from s15, got it from a nico member. i ordered a boost controller. so now i need to get the fuel pressure regulator, fuel rail and injectors. so just before i buy the SAFCII, should i use that or just get the tune from jim wolf(or someone else)?

sidenote: i called jwt today(3-4 week wait) and they said $595 for the reflash. has anyone gotten it cheaper from here, or know of another quality tuner for less? thanks, yet again

Personally I would get an AFC first. Reason for that is because... yes your car will run with the tuned ECU but thier tuning somtimes might be too conservative which will make you run rich, Like the JWT. They do that so there is no blame on them if you melt your motor down by running too lean.I've heard enalthpy is pretty good and a lot cheaper than JWT, not too rich not too lean. Anyhow the AFC first because you can make your car run good with just that, then when you are able to get a tuned ECU, you can fine tune it to your driving habits, climate,ect and still have the benifits of the data logging of the AFC and such. Again you shoud also invest in a WIDEBAND AFR gauge. Kinda pricy but worth every cent.Also running the T-28 I wouldnt push that thing past about 16#s. 16#s is 16#s but it will be alot more efficient that the t-25 at 16#s.

What really helps is providing the tuner with every piece of information possible about your engine. I gave Scott (Enthalpy) a list of everything done to my motor includind the fuel pressure and gas octane. My Tune is spot on to what i said. 11.6-11.8 AFR. You actually dont need an SAFC with a ECU Tune. Most are accurate enough to just tweak fuel pressure a few PSI if needed. Always check AFR with a Wideband before cranking up 16+psi.
