What turbo for 350bhp?
As title says! Im after 350bhp; but good driveability! I was thinking TD05 18g or VF35; but am not sure which is the best for power, and how the boost is exerted (good low down but bad top end and vica versa!)??

Yeah, a VF35 would be the most cost effective way; ive just heard they run out of puff quite early tho/or take a while to spool up(cant remember which one of the two!)??
What sort'a price is a brand new VF35?

The VF35 does'nt run out of puff, it will feel very strong in a classic and put a massive smile on your face.
Buy a low mileage 2nd hand one, mine cost £280 and came of a 21k miles 2005 STi.

Hi,
I've got a WRX 98 import with a TD05, it's got all supporting mods and a remap (all done in japan) and when I had it power tested on Saturday it is putting out 370bhp, The maximum boost it's running on is 1.35 bar

I think that figure is rather optimistic on a standard TD05 16g to say the least, especially at only 1.35 bar. Are you sure you dont have a bigger turbo in there that you dont know about!
Its generally recognised here that the TD05 16g is capable of a max of around 350 bhp at about 1.5 bar.

You would need to consider your gearbox, if its high on miles or had a hard life, from experience, it wont last long with 320 lbft of torque running through it!

I would say 320-330BHP is easily achievable without spending too much. 350BHP would be near its max and would need things like ported headers and STi8 Intercooler and mapped to 1.5bar.

But the gearbox is a thing I was considering, these are a weak point on the Classics arent they? What cheapish upgrade is possible if/when it goes?

Not much.
VF 35 spools slightly quicker
VF 34 has a slightly better top end
If power is your goal, VF 34 might be the better bet.
TBH with either of these turbos you'll be lucky to see a genuine 350 on a classic. Maybe if you get a decent front mount on there in addition to the other supporting mods, you'll be in with a chance, but I'd say 320-340bhp was more realistic (assuming you're using std SUL fuel)
There is no cheap option on the gearbox. You can get another 5 speed second hand at a reasonable price, but that may well go after not long too (depending on mapping and use), the saving then becomes a false economy. I'd budget for a 6 speed conversion or a PPG gearset and get it sorted once and for all: you're looking at 2k+
Have a word with David at APi.
