Default holset turbo 07 sti

just started reading up on options for turbos I see a lot of good things with people running holset turbos but with the limited resources I have on deployment I cant seem to find what you would need to modify to run one.

well like any turbo it depends on the size you are trying to run. what your horsepower goals are etc. if you just read some of the threads on here you will get an idea of what size turbo = which mods.

i dont know of any stock location holsets so you will have to run a rotated setup or some custom setup. that probably means you will need an upgraded fuel pump, injectors, manifold, up pipe, downpipe and a tune at the very least since i doubt you will swap to small turbo.

really the best way to start is to pick an HP goal and then have that determine which turbo/mods you will need. this thread might get moved too, this section is for proven power.

I did a quick search on "Holset" in this PPB forum. There are quite a few threads here. As the saying on Nasioc goes, "The search button is your friend."

first off im not sure if this is the right section but im sure one of the NASIOC mods will move it.

im in the process of a holset build right now using a HX35W off of a 98 cummins. MY turbo build on 3GWRX.com
i did a full rebuild ( blasted and cleaned everything and put in all new bearing's & seals) and put on a new BEP .70A/R Turbine housing (T3 to vband). Thats about as far as i have gotten. other then i have all my flanges and wastegate but nothing has been fabbed up yet to get it any closer to the engine.


their really isnt a whole lot of info on holsets here on nasioc i believe only 3 currently running them and maybe a few more in the works like myself. but everyone has a different turbo so far.

albersondh is running a HE351CW on a stock 08 EJ25 wrx eng and trans.
General is running a HY35 on a stock 02 EJ20 eng and sti 6 speed trans
Kotir is running a HX35W W/OE Dodge TS Turbine housing on a JDM EJ207 swap W/JDM TS Manifold

check out the custom welding and fab section for custom rotated setups to find out some more info on what needs to get them on the engine

Holsets are well know turbos over in the DSM/4G63 world. so do some dsm forum surfing.they have alot of info on the differances between all the holset turbos and how they respond.

thats what im thinking about running on the sti
i had great result with the hx35 & the hx40/hx35 hybrid
you would see around 20ish psi by around 3k
they would spool as a 16g and be able to run as much boost as the 35r
