hey buddy , let me tell my experience so far on the FI world.... summary ...
5 months in the work shop....
2 weeks of boost...
total cash spend about 9K USD
my kit is up for sale now for 3K
I bought a used kit since finding a new one is not an option ATM
was on a 2003 V6
and I fit it over a 2009 V6 had to do my own idler pulley
and because I live in a very hot area atm ( QATAR ) I had to go intercooled
and since I am automatic finding the pipes way was a hard task .
my kit was as the following
SDS with v5 blower
440CC RC injector
CX racing intercooler
custom made pulley and there for belt
map sensor
and a tune by hackish .
the car was doing (OK) in the week that I used it , had a good time with some local cars , that when they saw an eclipse they under estimate it , till you boost it a little that shut them up LOL, away from this childish play ... was good run , till I had a broken rubber mount for the axle lead to all the inside grease to go into the timing belt compartment and skipped a tooth , and boom , had to fix the car and spend about 3K to get it done and working .. and took the kit off, and up for sale here you go ...
as much as it would be better for me to just push you to buy the kit from me to make up some of my loss . let me advice you , and from there you go and do you open idea .
the kit is sure is fun . but will take a lot of time an effort , keep in mind if not done probably will damage the engine and ending up losing a lot of money .
PERSONALLY I think after that mode that car wont be a daily driving option , so better be having another car in the same time
if the kit was done right and tuned right, you wont be able to get super high number of ponies unless you upgrade your internals .I think running on stock engine is only boost 5 or 6 ... you cant run more , (someone correct me if I am wrong )
IF after all that and you still want to get the kit, all I can say , good luck , do a ton of reading and take from other's experience , and I have my kit for sale ATM everything above but the inter cooler .
