will evo 8 injectors fit?

[plv]

i have found a set of injectors off a mistubishi Evo 8 for $100. They are 560cc i think, low impedance, top feed, peak and hold. Will I have any trouble installing them on a ca18? like will they fit the fuel rail, etc.? is 560cc too big to run on a t28/t3 hybrid at 12psi?

You'll have to have the ports on the fuel rail machined a tad larger (like 1mm). That's what I had to do for my DSM injectors which are the same physical size as the EVO ones.

did u have a shop do it? how much did it cost? is there any injectors out there that will fit the ca18 without modification and is at least 450cc?

460cc and 550cc RX7 injectors fit from a tubo II. Just need to make sure they are the low-impedance version. But seeing as they are very old (20 years) they would most likely need a thorough cleaning. And as for the cost of getting the rail machined, I can't imagine a shop charging more than $10-15.

Never run FC injectors without cleaning them. You need to use S4 (88-89) TII injectors, but a lot of guys run premix in their fuel to avoid damage from a bad oil injection pump. The S4 was mechanical, meaning it was less prone to failure than the electrical pump on the S5 TIIs, but still, a lot of guys run oil just to be safe. They get so full of crud after a while, it is nuts.

i thought you guys have said the dsm injectors fit without any modifications, except for changing out the o rings??

thats what i thought too.

anyways thanks for all the info, im going to call a shop later today to see how much its going to cost to machine the fuel rail.
