I currently have a tdo4 turbo fitted 2000turbo (w reg), I am looking for an upgrade before getting it mapped in the new year, I am aiming for 300bhp, I am not bothered about topend power, the car is a daily driver (country roads) so the least laggy turbo the better. I know both vf28 and vf35 can both hit the power I wanted, I know the 28 is older but am I right in thinking its quicker spool? Another option is vf34 and tdo5 turbos there are slower spooling?

 

i run a vf28 on my 2000 turbo as daily driven car and its brilliant, spools fast, and makes the power.. a friend of mine runs a td05 and that is quite laggy in comparison.

 

vf28 (standard on sti v5 and 6) is a lovely little turbo, mine starts to spool around 2500 and pulls hard all the way! (305 with panel, decat and conservative remap)

 

I can only comment on the vf35 as that's what mine runs standard, it's not overly laggy but dies off quite early about 6k rpm

 

VF24 in my bugeye wrx (same as VF28) and from 3k on it pulls very well. Running a little over 300 with pink injectors, OS map and 3" turboback inc uppipe decat.

 

TD05 - awesome midrange punch and keeps going till the red light comes on

A bit laggy, but certainly does not spoil an average drive; and after all if you are out for a thrash you're not using the lower end of the rev range anyway.

I just love the push in the in your back from hand of God after 3.5k

 

I have my V5 sti remapped on the vf28 great spooling turbo! Can't comment on the vf35 but going but what I've read there isn't a world in difference between them.... They can be bought cheaper than the vf35 and there surely is good units around
