ok so i have been researching alot and believe i found my answer just looking for clarification . so im not being lazy i did my searching.

the number one thing is to find a turbo manifold that fits your turbo "4 or five bolt been told doesn't matter but dont know its true" and also be a/c compatible right or else you will have the problem with the turbo hitting the block.. correct?

second is running the right size down pipe to clear the compressor... correct?

i have a garrett t3/t4 4 bolt 57 trimm turbo. trying to boost my em1.

if it not to hard any suggestions to buy manifold and type(top mount, mini ram, log, etc...)

and suggestions for a good fitting downpipe.

 

pfab log manifold gives you plenty of room for a turbo and an 3" dp that one i know from experience

 

Oh ok . thanks did u also get ur down pipe from pfab?
