Ive been following Logans thread about his upgrade and he seems to have a lean issue while using his 3.4 injectors on his newly built 3.6.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Im moving along with my 3.8 unpgrade and I need to know if the 3.8 injectors are compatible with my 3.6 fuel rails. Obviously im jumping from 996 parts to 997 parts. I spoke to Suncoast and the parts guy told me he thought the 3.6 injectors were the same as the 3.8s so now im even more confused. Ive been following Logans thread about his upgrade and he seems to have a lean issue while using his 3.4 injectors on his newly built 3.6. I am trying to avoid any problem with my system so before I buy the 3.8 injectors I need to know if they will be compatible. Any help or advice would be appreciated. Cheers

POST 2Original post

I sent you a PM on this, but I too would be interested to know for certain. In short, I guess it would depend on whether the 3.6 and 3.8L injectors are the same dimensions, then you could just put the 3.6L orings on the 997 injectors. 3.6L injector orings 94411090101 7.5mm x 3.5mm oring (rail & riser) 3.8L injector orings 99970757440 7.52mm x 3.51mm oring (rail) 99970757340 8.3mm x 3.05mm oring (riser

Thanks Logan, just responded to PM.

Here are my notes from when I was looking. To me, it looked like it would work, but I didn't want to buy a 3.8 injector and return it if it didn't work, plus I found a killer deal on the 3.6L injectors. injectors porsche 3.8L 99760512300 = bosch # 0280158116 porsche 3.6L 99660612200 = bosch # 0280156053 If you want to dig into the specs page, here is a link to the data sheets and product info, unfortunately no specs for the 3.6L, only the 3.8L. http://www.bosch-motorsport.de/conte.../html/2659.htm

Thanks bud... I have a few calls in to LN and my mechanic. The injectors are $120 each. I do not want to buy them unless im sure they'll work without any modification.
