Eurodrive only does Topfeeds IIRC. Still give them a call though. ---

Topfeeds can be found dam near anywhere – for cheap.[/quote] bah they require resistor packs and those are more than the damn used gtr injectors![/quote] I believe this is only necessary if you don’t have the right impedance on the injectors themselves. I believe the SRs are high-impedance. For example, you can get MSD injectors which come in high or low impedance for quite a good prcie. SRs have 11ohm impedance (which is considered high) [http://toyotaperformance.com/injectors.htm](http://toyotaperformance.com/injectors.htm) ---

Hey are these injectors still available? I would like to take the offer pleeease, put me in for a set of 600’s :D…Oh and a date for when you need the money would be great, hopefully its like the 16th ---

yes it is still open, we actually havent taken advantage of it yet. there are between 4-6 people who have said that they would do it but i havent seen any $$$ yet so i havent initiated the buy. its been a crazy 2 weeks for me but for the guys who are serious we can do this anytime. ---

I might be down for this, just a few quick questions (that I was having trouble answering on my own)… because to be honest I’m learning all this car stuff as I go along :oops: Is there a “rule of thumb” when it comes to injectors? I’ll be using a blacktop with a T28, and hoping to hover around the 300 hp mark in a daily driven car… would 550s be fine, or should I step up to the 600s or 650s? Anything major to consider when going to the larger injectors? Also what else must be modified/added to a stock SR to fully utilize the larger injectors (ie safc, z32 mafs etc)? ---

i am getting 550’s with a Z32 mafs. the safc can do it i hear but you would be better off with either an upgraded ecu that has been set for 550’s and z32 mafs or with something more like an emanage or POWER FC the safc alone doesnt offer a ton of control, but there are people that can get it to do enough with just upgraded mafs and injectors. ---

An SAFC can really only correct +/- 50% … so it can do 550cc’s Anything more and you are going to want to step to a different system. J.J - if you are just looking for 300 with a T28 you will be fine with the 550cc’s…if you think you will use something other than a SAFC…perhaps a Enthalpy tune or standalone, I’d get bigger so you have room to grow.
