Ok, what is thought to be the best size header for tial 3076? 45mm or 50mm thanks for any input

 

Ported stock manifolds would be fine for your setup but if you really want to go to a bigger header, 45mm is plenty. 50mm is huge

 

Great stuff, thanks. A local shop sells dtek 45mm for £500. Seems fair. Just want to get the basics for running these turbos first then save for a while to get some extras followed by an engine build! All this without alerting the wife to what I’m spending again

 

Some create more HP, but some don't. Ported 997s, which are just a little better than 996 are a viable option too.

 

Just want it to help spin up and not restrict flow to those 3076 turbos

 

smaller headers = higher port velocity...might help spool..

 

Would that restrict flow up top though? Is that the general consensus? Smaller for faster spool and larger for more high end flow? Thanks
