set of 6 flow matched injectors, 450cc

Found info on install, only question remaining is whether I will need other mods to use these with a stock fuel system and a walbro 351 fuel pump.
A lot of people use some kind of air fuel controller, but I have no idea if that is necessary if you aren't upgrading turbos yet.

These injectors include o-rings and are blue top. Mileage is 65-75kmile, all flowed within about 1% of eachother. The 450s will require the ECU to be retuned. I will keep the 180 offer in mind but at this stage will hold, I also have a set of 390cc for sale for $180obo if that is of interest to you.
A point of interest, the 390s may not require the ECU to be retuned, the ECU may be able to drop back the pulse width enough for them. I know The DSMs can run about another 15% bigger without retuning or any other ECU mods so it might be possible to run 390s on a 3000GT without upgrading the ECU.

I wouldn't swear to it, but I think that anything bigger than 400's you will need an afc. I think the stock ecu can accomodate 390's, but I'm almost positve it won't hardly run with 450's without an afc.
390s
This set of injectors all have about 50kmile on them, they are the later style wide spray style and are all flow matched, identical fit etc. Actually, I was thinking the stock inj were 340 not 360 I am almost certain now that the 390cc will run with the stock ECU. It would be interesting to try this out for sure.

To answer the question, YES ABSOLUTELY you'll need an A/F controller for 450's.
Think of it this way, stock is 360, 450's are about 25% bigger (quick math). So you'll be runnng 25% richer. The car will foul plugs almost immediately.
As far as I know, our ECU's can't really be reprogrammed (DSM's can). And at $325 for an S-AFC it's better just to go that route.
BTW you can pick up 450cc injectors (not flow matched) for around $70 for 6 of them. Then $10-15 each for cleaning, I think an extra $5 for flow-matching. So really $200-220 is a decent deal, considering you don't have to go thru the hassle and wait of getting them cleaned/matched.
