then buy BMR K - Member " fit the extra exhuast piping
42Ib Injectors
and is their anything im missing for my car to run. and is JDM a good brand?
going to run 6psi on "DD" and 8psi on Drag

Thats the kit i bought and i hate to say it but better off buying the godspeed hotside and go from there... The jdm bov straight up doesnt work and youll pop pipes...

The jdm wastegate leaks soo much internally its useless

The to4b is wayy too small my ls1 wouldnt rev past 4k

The cold side is good and hot side is ok... Best way to go is get a bmr turbo kmember and do a custom downpipe and save all the big headaches... You gotta relocate fans to front too... Dump wastegate... Get solid umi mounts(work with bmr kmember over other solids)

Use header wrap and turbo blanket... Relocate alt to top... Custom or bend power steering pressure hose and redo return with an external cooler...

Thennnn your factory ls1 valve springs will valve float under boost(mine under 5k)...

But after all the b.s. i now have a fun car... My t67 builds boost pretty fast too...
