wastegate question for a mhi 20g setup

[mattgbade]

So i finally got the last piece to my 20g setup and was ready to install and then change of plans i have decide that i want to run a external wastegate gate instead of using a internal setup with my fp manifold with adapter plate dont know what external wastegate i should use being as i have never used a external setup....my mods list to be installed after this is resolved is walboro 255, precision 850cc injectors, magnus fuel rail, aeromotive fpr, dsm kink v2, fp intake, full 3" exhaust, maperformance front mount kit, GM MAF and i am runningbthe 10cm compressor housing. Any suggetions would be awesome thanks!

Single 38mm gate off the o2 housing would suffice. Although, some units can get pretty pricey, be prepared to spend some decent money.

I use a Tial mvs with punishment racing O2 dump and FP manifold. It works and fits great, as long as you install the FIRE RING... that being said, it was a lesson learned. Good luck.

You can't run an external gate anywhere but the manifold with that turbine housing...and the FP manifold has no wastegate provision. This means you'll either need to trade your turbine housing for a DSM bolt-on housing set up for an external gate off the o2 then buy an appropriate o2 housing to suit, or trade your FP manifold for a T3-flanged manifold with an external gate provision.

Sorry i should have said im ditching the fp manifold setup and purchasing a actual t3 manifol possibly one from stm
