Recommendations for pulley

[bfox507]

Hey guys I currently am in the process of rebuilding a l32. I'm using an xp cam, zzp CAI, northstar TB, zzp headers wit hi flo cat DP, and res delete, colder plugs upgraded fuel pump and bosch green giant injectors. What would be a good place for me to start with the pulley size I currently have an 3.4 mps from a previous build would u guys think that I start off wit that and that pulley would be safe for me to run with the current mods I have. I have a scan tool but just want kinda like a theory if u guys think that pulley is either too small or just right for my application. I really don't wanna spend an extra money for a new pulley but will if needed I'm just tryin to hit the pulley size on the first try. I will also be gettin a custom dyno tune from a local shop in my area after this is all put back together.

3.4 should be fine just remember to scan scan scan scan and get it tuned

With a cam, 3.4 will be fine. I have same mods basically minus cam and am running knock free with 15° timing. Think I can take it up more too. Only knock I get is in 4th under load, but I think I should be able to adjust tcc for that, haven't tried yet.

If I end up using stock injectors would could I use the 3.4 pulley or do I need to use a 3.6?

Stock injectors will be more than enough for you, with gas anyways, E85 definitely not. Stock injectors were enough for me down to a 3.2 (smallest i've run) on an xp L36, that was with an SSIC though, idc was around 80% I believe. Without the IC, probably would've been cutting it close.

Stock injectors are good for 3.2 pulley and bigger. I wouldn't bother with the N* and injectors until you need them
