New Turbo choice?

[prodrive tony]

Sod it, if i'm rebuilding my engine I might as well upgrade. I have a uk98, will a td05 16g be a good choice or shall i go for a vf turbo? Thanks.

go for a 18 or 20 g but 16g should be fine for 300bhp

Depends on how far you want to go

Think you have a TD04 as standard and Andy Forrest can do a hybrid TD04 which is good for about 330bhp and has very good spool up and virtually no lag

Then you have the VF series turbo's as used on the STi's, i have a VF34 which should be good for 350bhp, they spool up slightly later (about 500rpm) unless you have some ported headers as well which make it spool up just like a TD04 and this turbo pulls all the way to the redline

Then you have the TD05 turbo's (16g, 18g, 20g,), not sure about the 16g but these are bigger turbo's and will have more lag and spool up later but you will get a bigger hit and i think the 18g or 20g is good for around 380-400bhp at least

So it all depends on what you want, a fast everyday car that is easy to live with then i would go for a hybrid TD04 or VF34/35 otherwise big power from the TD05 18g or 20g but it will be more laggy

Personally, I would go for a 20G and have the option to mod it more later.

You can pick them ipf for £600, with quite low miles second hand.
