the T25 sounds like the perfect budget kit.
like someone said ealier, the T25 is very cheaply upgrade, and i'm sure the SS FMIC will fit w/out too much modification at all (probably just getting some new silicone connectors would work)
It remnids me of the GReddy kit for the 1.6L Miata (except much better quality). Cheap, but very versitile and accepts lots of other options down the road.
but IMO, throwing in the FMU is almost a must. unless there is another way to control the fuel in stock form?
