LTX-8 and injectors help
 

Im running an old LTX-8 and a pair of 550's and a pair of 1680's, always had problems with stumble on the transition from primaries to secondaries.

ANYWAY, Im looking at new injectors with the new engine and turbo set up, but still keeping the ltx-8 for the time being.

The Question is;

What size injectors should i be looking at for the 400+ whp range that would be easier to stage, with no STUMBLE on transition, and where do i get them?

Im thinking 4 x 1000 might be border line?

1000s and 1200s?

4x 1200? Or would that create idle issues?

are these guys ok?

1991 MAZDA RX-7 R2, 1.3L, Turbo, GAS Fuel Injectors

^ that was supposed to be a link to the 2x 1000 + 2x 1600 package for $400 from them

Any recomendations?

The reason i'm leaning on you guys for this is there is a shortage of rotary tuners where i am these days, same reason im sticking with the flintstones ecu as everyone around here seems more comfortable with them. Will possibly upgrade to an Adaptronic in the future.

Basically, iv got no fucken idea, but need to get some parts together so please be gentle!

Also i might add, that its a Turblown tdx61. (i find if i say Turblown, he magically appears, lol, Elliot, I appreciate your advice mate!)

I bought 4 Id1000 for my FD which had a lt8 plug and play in it. The Main reason I took that route was to ease on tuning. But everyone said its only enough fuel to flow nearly 400hp that's it. So I'm changing the secondary to 2000cc which should support 500hp. The staging on injector dynamics are easier and better to tune then low impedance Bosch. So staging will come easier!

Its not the injector size that is the problem, its mainly the tune, and the lack of dead lag settings in the ecu software( unless its been changed since the last time I used one).

4 x1000cc injectors is barely enough fuel. I would do 1300 x 4.

Ok thanks. I ended up having my existing injectors cleaned and tested. Im just going to use them to get car running and to run the engine in, will upgrade to a modern ecu and injectors after that.
