Precision wastegate, Precision intercooler, Tial BOV, and a 6262 Precision turbo.
Internally actuated waste gates are not my cup of tea.
You havent seen the new Borg Warner EFR turbos then.
They started with a blank piece of paper and made an internal waste gate like it should be made. The new EFR turbos are not ANYTHING like the old Garrett turbos. The small ones have 36mm w/g ports with divided flow housings that channel as much as 40+% of exhaust gases thru the waste gate opening.
Look it up. You will be incredibly impressed with the design.
If you need to "fully trust" your items:
- Garret turbo; Let me say it again, Garret turbo.
- Tial or HKS Wastegate, Deltagates have been known to boost creep a little under
load. The wastegate the one part you do not want to cheap on.
- HKS or Tial BOV, this one really is just personal opinion. The HKS SSQV and the Tial Qbov50 are great pieces and sound the best.
Borg-Warner makes the best turbochargers on the market, period.
HKS no longer sells parts in the USA. TiAL makes a better BOV and actually sells rebuild kits.
tial blow off valve or turbo xs, tial waste gate, comp turbo (triple ceramic ball bearing with billet wheel) the best turbo by far. believe me i have tried a bunch. by the way borg-warner is a lower end turbo not high end. dont get me wrong they are an ok turbo but not the best. i can name several that will make more power per pound of boost and spool up faster also.
I prefer Cast Iron Exhaust Manifolds but since non are available Id have
