vf23 fit with my td04 manifold and downpipe?

[tobiah]

Will it? my td04's smoking before my mapping so need to replace and saw that these are good ball bearing turbos and good for a little more power than td04?

 

[goldenvtr]

yes it will and it will be a fair bit more laggy

 

[tobiah]

really? is it not ball bearing? i heard the spool would be coming on around 3500 and full by 4000 on 4e?

 

[goldenvtr]

yea it ball bearing but its still a fair bit bigger, my mate used to run the turbo im running on my 5e at the moment which it smaller that the vf22 and he wasnt getting decent boost untill 4500.

you may get posotive pressure from 3000 onwards but not a chance you would get 1bar by less that 5k IMO

 

[weakboy2]

he said vf23 mate, vf22 is massive. VF23 has the smallest exhaust housing of all the STI VF turbos IIRC

I'm not sure how accurate this information is:

VF22 (Part Number: VB660033) 485 comp wheel and P20 Turbine Housing. Ball bearing turbo.

VF23 (Part Number: VH660035) 467 comp wheel and P18 Turbine Housing. Ball bearing turbo.

VF24 (Part Number: VB660049) 467 comp wheel and P18 Turbine Housing. Non-ball bearing turbo.

VF29 (Part Number: VB660057) 467 comp wheel and P18 Turbine Housing. Ball bearing turbo.

VF30 (Part Number: VD440017) 479 comp whell and P18 Turbine Housing. Non-ball bearing turbo.

VF34 (Part Number: VB660060) 479 comp wheel and a P18 Turbine Housing. Ball bearing turbo.

VF35 (Part Number: VB440022) 479 comp wheel and P15 Turbine Housing. Non-ball bearing turbo.

someone i spoke to said 3.5k 1bar for vf23 and slightly more power than td04

 

[mcleod]

get it and find out mate you'll get more than td04 power too

Yeah i was wrong, vf24 is smallest, has the P18 housing. VF23 has a P20 but matched with the vf24 compressor side

Has anyone any experience with a VF34 on a 4E?

 

[weakboy2]

mcleod has a VF34 fitted on his!

Rare to come by second hand and expensive to buy new!

Deffo going to try a 24 on my car as it seems the next upgrade from td04 on a impreza as far as keeping driveability goes, in theory should push 300 too

 

[tobiah]

thanks. I've seen those comparisons. look interested. found a used vf23 for £270 wonder if its worth a go. spool compared to td04 on 4e is my realy interest

I'll be interested to see the outcome. I've the opportunity to lay my hands on a low mileage VF34 for plenty cheapness and so was considering it as an option for getting a bit more go out of the old bus.
