Only replace them if your going with a aftermarket e.c.u also. It will run rich if you were to just chuck bigger ones in as the factory e.c.u is still controlling them at the same rate as the 365's. With a link etc the inj pulse can be set by the tuner to give the engine the correct a/fuel ratio.

yea i have a link. wiring it it this wekend. anyone else have any opinions?

only bother with it if you're going to be turning up the boost until the original injectors run out of puff. best done on a dyno by a pro with a close eye on AF ratios.
i dont really see any point in changing them over for the sake of it if you're not going to be pushing the stockers past their limit.

its going 2 be dyno tuned when the engine is complete, dose any 1 know if the standard injectors are good for around 12psi boost?

What sort of power you after? Stock 365s to 200hp - 440s to 200 kw - 550s will give you more than youll ever need.

well i want 2 give it as much as i can get without having 2 buy a new engine in a couple of weeks! if the standard injectors r all that stand between me and a few more kws, i will get bigger injectors. im trying 2 find out if thats worth doing if the rest of the engine is standard? (apart from being turbo and a link computer) wat do u think?

So no, don't put them in the 4agze...they wont fit.

440's would be pushing it for 200kw @ wheels.

Depending on when you need them, I will be selling my 540cc Supra injectors.

by **sergei** » Sat Jul 22, 2006 1:11 pm

ST165 injectors are top feed. low impeadance ~440cc.
