Hey guys Im looking to get the biggest stock frame turbo available. Not too worried about the boost lag as I enjoy that top end snap and I also want the room for more potential. So from what I found so far Map ef4 and the gt35r seem like good options. I would consider the fp black but on their website it says they need a core and Im really not trying to deal with me sending my turbo and all that. If you guy know any other massive stock frame turbo please let me know and also which would you recommend out of ef4 or gt35r.

 

The MAP EF4 is the largest bolt-on stockframe turbo you can buy. Its a proven turbo capable of 600+ WHP.

 

thought so...its pretty good price too...what would you recommend at the minimum for internals? Is there some compatibility issues or can I simply go with the most aggessive cams money can buy and some springs/retainers? Ima go big or go home type of guy

 

If that's your mentality, get AMS' camshafts. They should pair nicely for big power.

 

The Map EF4 is the largest stock frame turbo currently but most are saying the FP Zero will be the next big thing for stock frame setups, I would just wait a month or two just to see if its ever comes out currently its being tested

 

I would be more than happy to help out with your build! From picking internals to getting a sweet deal on the turbo, just let me know what I can do! Feel free to shoot me a PM and we can discuss it!

 

pmed!

 

Curious to see where this goes.
