I want to put s4 t2 injectors in my na. I just want to know if they will fit with a little lube.

The reason for everyone before you flame me, I am running a haltech and I can't find a base map for my 87 s4 na engine. None of the t2 maps work and I think it's because they all are setup for bigger injectors.

I haven't bought them yet but if I do I want a cleaned and flow tested pair.

 

That's a terrible reason to use bigger injectors. The base map is purely to get the engine running, then you tune it. Any decent tuner should be able to start the engine and get it drivable from scratch, without any base map. If you're doing this yourself then you should be able to pull enough fuel out of a Turbo map to start the engine, and tune from there. New injectors is just a waste of money.

 

that exactly is the problem I have no idea how and I need to get my car running asap.

 

Get a base map for a STOCK TII and remove fuel. The stock 460's are already more than enough for even a mildly modified N/A. Remember Mazda designed the FC to run overly rich for longevity, in a time when the rotary's reputation for reliability was in serious question. Talk to Kahren, he should be able to get you a decent tune.

 

Also don't forget to play with the timing. IIRC the Haltech base map already retards the timing in relation to boost, so you'll wanna correct that.

 

The TII injectors are a direct replacement.

But there is a much easier solution. First, try and see if the car runs as is. It should run well enough to be driven. If not, then use the built in functions of the Haltech software (scaling...Uh, I think you press "S" when in 2D but check the help) to add or remove fuel over the entire fuel curve.
