My00 classic is running 250bhp 265lbft of torque, but I want more!

It has,
a full de cat exhaust
cotton green panel filter
walbor fuel pump
remap at scooby clinic.

Now what shall I do?

Bigger top mount intercooler? If so, which one?
Or, a front mount?
Bigger turbo? TD05 ?G or VF?
Different injectors?

Anything else?

Don't want to go to the expense of changing the internals.

 

250BHP is a bit low if it's been remapped. You should be getting near to that without a remap and those mods.
A remap running 1.1/1.2 bar dropping to 1bar should get you 270-280BHP.

The standard Top mount is good for 320BHP, as are the injectors. But you will need a bigger Turbo i.e VF24/VF28, TD04 Hybrid or TD05 to get there.

A VF28 running 1.3bar should see 300BHP+

 

I was a little disappointed to .
So just go for a vf28 then and map of course

 

i'd personally go for the vf35 or 34 and a remap
just incase you get bored again and want more power

 

What sort of power should i get from a vf 34 or 35? And what is the difference between them?
And do i need anything else with one of those turbos?

 

not much difference between them, the exhaust housing is larger on the 34 = slightly more top end, however the smaller housing of the vf35 = quicker spool up.

the vf34 does have a roller bearing that aids its spool up slightly. where as the vf 35 is sleave bearing.

there seem to be more vf35's available second hand, and generally to go for less £'s

i reckon you could achieve between 310 - to 325 with your mods.

 

i have to agree just get the vf34 or the vf23 for mid to top end power

 

Glad people have found my experiences useful. The upgrade I had is tried and tested. Just my two cents, at this level of application I would go with the quicker spooling turbo, which also happens to be the cheaper one.

TBH Most people I've spoken to say there is little between them.

Thanks alot. Sound like a vf34 it is.
But do i need to do anything else?
And dose anyone know where i can get a vf34 at a good price?

 

VF34 or VF35 would of been my choice but VF24 and VF28's come up a bit more often and are considerably cheaper. I paid £180 for my VF28 18 months ago.

 

cars varry, and its not the lowest i know of (that onlyt hit 245bhp) no mater what they did to the map. exact map then went on another car and ran 255bhp without any tweeking.

bad news is it sounds like you got a not very good engine, nothing wrong with it mechanically, just not as close matching tolerances with the parts in it compared to some.

 

High mileage?

 

cheapest i have seen a brand new vf34 is from flat 4 online for £675 (and free postage!!)
haven't seen too many second hand,

lots more vf35's available second hand though, tend go for about £300

vf28 is the sensible choice (and cheaper) as you definetely wouldn't have to upgrade the intercooler, and makes the possibilty of breaking the gearbox less likely.

imho

 

No mate it has only done 38,000.

 

I am liking the sound of the vf28. Only want to go to low 300's and don't want to blow the gearbox.
If i could get a sti8 top mount should i bother?

 

VF28 would be a good choice, std IC will work but Sti8 better, FMIC best especially if you use WOT a lot, get some ported headers from Harvey as well, a remap to compliment your new mods and it will be a real nice strong daily driver.
