What size injectors would you guys recommend? I'm looking at some 30 lb. I have LT's ORY 243's 11:1 compression and this cam..

i'd go with 42's because it will leave you room to grow if you decided to spray it or put better heads on it and so forth

I have stock 243 heads and 28.8lbs injectors too and 65% at 5500 doesnt sound all that terrible.

G5x2 and over 90% duty cycle with 28lb injectors and stock 241 heads. Tuner said I SHOULD even upgrade them now, def if I did anymore upgrades.

Give it up guys. You cant help someone that wont let themselves be helped. Have fun leaning your car out.

If you do not port the heads I would suggest going with the 230/224/111LSA cam. Has the driveablitly of the TR224 but will make more power. If you do go ahead and port the heads the TR227 Extreme would be a pretty good choice for what you are looking at. Specs are 227/227/ - 116 LSA. Lift is .639/.639. It idles similar to the 224 but will utilize the flow of the ported cylinder head better. If you decide to go with the 230/224 you will not have to change springs, but you will definitely have to change the springs with the 227 extreme. As far as the injectors you should be fine with the stock one. Let me know if you have any further questions or if which direction you are looking to go.

I'm not sure which one of us replied to that e-mail, but I assure you that there was a missunderstanding on the spring issue. No one here would suggest running ls6 springs with our TR230.

As far as the injector issue goes... Get it to a tuner and he can tell you what you need. Although you are getting to the point of upgrading, stock injectors should be ok with this combo (we have done a few ;) )

Yeah, I know I am fine. People have good points and I already considerd resizing them well before installing the cam, maybe I will do that this winter in anticipation for finer tuning or future upgrades. For now its fine, plugs look good, no overheating issues on the highway, its running well.
