ls2 c6 228r boltons
ls2 c6 228r boltons just got an 06 c6 ls2 a6 just hit 80k. future plans im looking in to getting ls3 heads and pro charger d or f 1 but that's no time soon. nitrous is for the time being awaiting the pro charger. im going with the 228r cam stock heads and 100-150 shot to have some fun for now. im NOT trying to to blow it up.
i have already done tsp 1 7/8 long tubes 3' orx and custom x back with dyno max mufflers k&n filter that's how she sits now. just swapped in 228 r cam this weekend. street tuned on monday.
what have you guys hit these things with? safely with cam and stock fuel pump. injectors at 85%
nos plate kit, mini progressive controller, fuel press safety switch. im thinking the lcn2000 from lingenfelther for timming and window switch.
still have stock intake man and intake wit k&n drop in. is it worth it getting and air aid kit now with a cam. what bolt on's em i missing ? ud pulley worth it??
car runs strong just looking to see if something could be holding me back?

I would absolutely look into a new intake and cai. I bet theres 25 hp sitting there alone with the cam. As far as now I can see 390-395whp but with a fast and cai I can easily see 420
was thinking about ported ls2 intake and ordering an air raid cold air this week..
Yes I've read a few things stating that as well, but if you dig a bit deeper you will see that the Fast dominates...maybe not always with impressive peak dyno numbers but with track applications and so on

at .588 lift what do your heads flow? I have heard the heads flow well up to .600 lift, maybe a set of rockers would be better
Adding more air into the intake will only help if your heads are starving or lacking the charge.

im currently running the stock intake with k&n's. the radiator cover has been pulled out and now the stock box looks awkward. so im looking for cai.
im running the cam on a single spring i don't want to push it. I'm pretty happy with the gains. just looking to well match up the combo. later on ill get the 3200 stall but im not ready to bring down the rear. i do everything my self and the rear would be a pitta working on jack stands.
i'm just scared of investing on a fast and a lil nitrous back fire blow it to Pisces...
you put the rockers on my mind the rocker will increase lift on the set up but will it put more strain on the springs? im thinking it would. i have comp single spring 600 lift i believe...
I would already be running the Lunati dual or BTR spring kit on there as those cam lobes will tax the limits of a beehive and you seem concerned about it.......you certainly want to avoid this..

Also porting the ls2 will still cost 200 or more and then you'll still need to get a retune anyway. For a few hundred more you can get into a fast that will still handily out perform an ls2 even ported. The ls2 just isnt that great of a design all around. The gains from a fast dont come from just increased airflow but more so from the more efficient runner design. With my stock 243's I consistantly pulled vaccuum at wot in my car with my ls6 intake which is known to flow more than an ls2, a fast will always gain power over a gm intake with cathedral heads.
With your setup I could easily see a fast picking up 15-18hp seeing as they normally pick u 10-15 over an ls6 and the ls2 is worse than that. The 90/92 fasts are good but the 102 will make more power, has various runner options if you ever want to swap them out and its built better.
I assume you're talking about 1.8 rockers, in which case thats a very bad idea. The 228r is ground on xer lobes which are pretty violent lobes in terms of beating up springs and lifters. Adding a 1.8 rocker is going to make that worse. A 243 head is all done at .600 stock so .588 lift on the cam upped to over .600 with the 1.8 wont do much at all.

came off my old build. i was thinking if they could be made just as good as the 243's? they should be identical other than the combustion chambers... will i run in to issues milling them to get 11 11.5 to 1 ? i know there's issues with milling them for the 5.7 to get them that high in compression...
