LS3 with twin 67mm turbos... Which injectors/valve springs?
 
Not gonna push it too hard with boost. Gonna keep it stock as its a crate motor. What size injectors would be good its staying on 93 gas? Probably 12lbs tops. Which valve springs as well?

I would think 80# injectors. Are you going to swap the cam? If not I may consider, just leaving the stock springs, otherwise, what cam? I generally run BTR springs. Best bang for the buck.

No we are gonna keep the original cam. But I do feel like a spring swap may help it at least a little bit in case we do decide to start turning it up.

80lb injectors would work nicely for that setup.

Pac 1218 springs are cheap and work well.
BTR springs would be better.

Can anyone link me to the right kind of injectors?

Just do a set of ID1000s. Great injectors and will give you a little extra room if you decide to add a little power.

vettewreck 01-11-2019 09:57 PM

Unfortunately those are out of budget. Anyone have a link to the correct set for a LS3 80s?

You want Siemens 80 lb short with ev6 connector for ls3. Plenty of injector data online for those. I would get real ones, not knock offs.

Perfect thank you!
