Just wondering if there would be any benefit to fitting a vf 23 roller bearing turbo to my96 uk turbo?Currently it makes 294 bhp and 251 lb/ft @ 1.1 bar boost with blitz boost control,blitz stainless air filter,blitz nur spec r(full system),de cat down pipe,440cc injectors and mapping from power engineering.
The vf 23 has been converted to fit early classic so would fit but would it spool up earlier and would there be any real benefits over standard td 05?

I think you'd be better sticking with the TD05. My VF23 makes 1bar at 3k in 5th, and I've considered going for a TD05 as I've read that they spool faster than a VF23.

as far as i was aware there pretty similar at lowish boost, until the top end where the td05 would hold more

if this is the case i cant really see why it would be worth changing it

Thanks for the advice,what turbo would give the best response if i did decedie to change it?and would different headers help a great deal if i kept the td 05?any recomendations on either?

If it was me then I'd look at headers and intercooler first. The TD05 will take a lot more boost, get the best out of it first.

And TD05 can be easily modified to fit larger compressor wheels...

thanks,i've already fitted an my99 intercooler?i do have access to a vf28 so i could try it and see how it goes?would it be worth the effort?any recommendations on headers?

AndrewC

VF28 is smaller than a VF23, it may spool quicker but not significantly quicker than the 05 if you've got decent boost control. TD05 will make more power at the same boost.

As for headers, I've had GruppeS v2 on my car for more than 18months with no problems and good gains in power and torque, GT-Spec are similar but with a 3-bolt uppipe flange which is meant to be more robust/less leaky.

thanks andrew,i was thinking about equal length headers as i've heard they aid spool up?i've also considered a vf 24 but am not sure if i should just stick with the td 05?has anyone else had good results with equal lenghth headers on td 05?
