im looking to put a turbo in my 91 ls someday and im gonna try to it myself by getting all of the parts i can out of the junk yard. my question is what are the ratings on some honda injectors. i was gonna go with the dsm 450 cc's but if i can find some good ones from honda (350 - 450)i would rather use them so i can represent.

 

There aren't any that big....go DSM or aftermarket. I believe the Bseries injectors are 240cc..

 

i figured that none of the honda injectors would be that high since they dont come with turbo from the factory, but what about preludes ? i heard they were around 350 or so.

 

They're not even 300.

 

If you can get some Lucas plate type injectors, those are probably the best on the market and will flow the best at up to 80% duty cycle. Also, figure out how much power you really want to get out of the motor first, if you plan on building it or just plan on running 8-10psi on stock internals. This will allow you to determine what injector size suits you and can save a future switch.

It is much better to go bigger than needed and have an injector loaf all day than it is to have it barely adequete and run at 80%+ duty cycle. Spray patterns and consistancy of fire will become inconsistant and the stress can also lead to premature injector failure.

Just something to think about.
