You can use FJ20ET injectors and they fit straight in. You just remove the rail and cut off the hose and swap the injectors with new fuel hose. Just cut the lengths correct so it fits up like stock.
ACL Pistons, 226/236 cam, T28 Turbo, FMIC, FJ20T Injectors, Wolf V4 ECU, NPC Clutch, VL TB, Custom High Mount Manifold, N13 Internals G/B, 3" SS Exhaust, Walbro 500hp Pump.
237hp@18psi
13.52@108.95mph (street trim, leaky hg)

i owuldnt put the injectors in till u get the microtech in unless they are slightly larger(within 10%) sa teh stock ecu will treat them with the very same pulses meaning severe overfueling in some cases.
but to answer u Q take the balck plastic bit off and slide them over the ne ones and depending on the type of injectors u get it depends on how they hook upto teh rail. the type that havea barbed end are the same a the E15et and injectors like the CA18 slide into the rail which are different all u do with them is remove the little rubber oring and slide a piece of hose over it and put a clamp on it well thats all i did anyway

there were some ca 18 injectors that came out with the barbed end but i forget which year. id go the fj injectors although they are getting hard to find. got to fj20.com and find some there. as panda said just slip of the plastic part then the metal bit will come off, you may have to remove the rubber rings to put them on to the new injectors.
What sort of power are you looking out and what boost. if you plan on running high boost and you have the money, it would be worth buying those rx 7 injectors, heaps of flow, and they have an excellent spray or so ive been told
good luck

first remove injector, 2nd remove the plastice black piece, under the plastic piece there will be a rubber ring, its pretty tight but you can remove it, but dont damage it because you still need it, after thats gone you can just simply slide the metal plate off.MRET2U wrote:yair i know how to go about the fuel rail side of things but the metal thing that is on the injectors then the black chock thing then it bolts to the head? you know that part? sorry i should explained it better but dont know what its called thats the part i need to know how to get onto other injectors

Sorry if thats confussing.
and yes paul is correct, dont put bigger injectors in with a standard computer, if your worried about fuel at the high end of the revs just add a malpassi rising rate.
