You dont need to change the ecu, you can go for a tec 3 remap along with a de cat and you will be looking at around 270 ish bhp
If you do want to change the turbo then a few have changed to a vf28 with good results.
Best get it all done at the same time to save on mapping costs.

Found the following info on the VF series turbo's, might help your selection?

IHI Turbos

VF22
This turbo has the highest output potential of all of the IHI VF series turbos and is the best choice for those who are looking for loads of top end power. The top end power however, does not come without a cost. The VF22 spools significantly slower than the rest of the IHI models due to the larger P20 exhaust housing and is much less suited for daily driving than some of the other models. Although the largest VF series turbo, the VF22 is not quite optimal for stroked engines or those who wish to run more than 20PSI of boost.

VF23
This turbo is considered a great all-around turbo. Like the VF22 it utilizes the largest P20 exhaust housing. This housing is mated with a smaller compressor housing of the of the VF24. This turbo is considered optimal in applications with range from mild to slightly wild. It does not have the same top end power of the VF22, but spools up significantly quicker.

VF24
This turbo shares its compressor housing with the VF23 however, this housing is mated with a smaller (P18) exhaust side. The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group N rally cars.

VF28
This turbo came standard on the STi Version 5. In terms of overall size, it is smaller than the VF22, VF30 and VF34, and about same size as the VF23.

VF29
This Turbo is nearly identical to the VF24, with the same compressor and exhaust housings. However the compressor wheel in the VF29 is has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such this unit is typically chosen over the VF24.

VF30
The VF30 is commonly considered the best bang for the buck turbo in the IHI VF series line. A relatively new model the VF30 features the same exhaust housing as the VF24 but a larger compressor side similar to the VF22. The combination of these two parts results in increased output potential without the lag associated with the VF22. Although it doesn't offer the top end supremacy of the VF22, the VF30 is a great compromise between these unit and the quicker spooling models.

VF34
The VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30.

VF35
VF35 The VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY.

VF36
Roller bearing version of the twin scroll VF37, also has a titanium turbine and shaft for even quicker spool. Same compressor housing as VF30/34, however twin scroll P25 exhaust housing provides slightly better top end output due to reduced exhaust pulse interference. This turbo is good for 400HP and used on JDM STI Spec C from 2003 onwards.

VF37 (thrust bearing)
Enter the age of twin scroll IHI turbos. Same compressor housing as VF30/34, however has a new twin scroll P25 exhaust housing that provides slightly better top end output due to reduced exhaust pulse interference. Twin scroll also provides better spool up for improved low down response over the VF30/34. This turbo is good for 400HP and used on JDM STI from 2003 onwards.

VF38
Twin scroll turbo with titanium turbine and shaft. Smaller compressor housing than VF36/VF37 provides tremendous spool up capabilities but less top end than VF36/37. The spool capabilities of this turbo are demonstrated on the JDM Legacy GT, which reaches peak torque at 2400RPM.

VF39
Single scroll turbo used on USDM STI and latest 2.5L STIs released internationally. Smaller than VF30/VF34.

VF42
Exclusive turbo to the S203/S204 models, this features a twin scroll design with a slightly larger compressor than the VF36/37 turbos and different turbine design (more blades). The VF42 is a roller-bearing turbo and is likely of similar size to the VF22 turbo, but with twin scroll exhaust housing for faster spool and superior top end performance due to reduced exhaust pulse interference.

What year is your car??? If yours is 99 onwards this can be Ecutek for around £500-600 if it's older you'd need to go apexi which is around £750

It's very easy to pick up cheap turbo, I picked up a VF28 off ebay for £125 which had about 70k you'll pay a bit more for a low milage one.

If I were buying a new turbo I'd probably go for either the VF23, VF30, VF34 or Andy Forrest Hybrid TD04 - depending on the power gain and power delivery characteristics that I wanted.....oh and budget of course.

A remap will set you back around £600+, I had mine done at Powerstation but if I did it all again I may well have gone for a Bob Rawle remap. He's based in Swindon so is as easy to get to and has a great reputation, (no complaints about Powerstation because they do all my other work, I just think he's probably got better mapping experience).

ok cheers fellers for the advice. my car is a 2000 modle v reg, iv seen a td05 on ebay for about £400 i think is that one ok, do any of the remap places sell the ecu's and then get the car maped there the same day.


thanks

If you go for an Apexi they'll fit it and map it for you. They'll also fit the turbo at the same time, but for all that you're probably looking at over £1k plus the cost of the turbo......

Unless thats brand new thats well over the top. TD05 FE normally go for around £250-300 but theres a couple of scoobynet

Vf23 https://www.scoobynet.com/turbo-sale-t546124.html for £150


VF28 https://www.scoobynet.com/vf28-turbo-sale-t544882.html for £200

My VF28 on My99 with the FMIC made 317BHP on Powerstations rollers. Jump on a group by for Ecutek @ £587, I Can't remember what I paid to have the turbo fitted but it was only a couple of hours labor.

I paid £120 to get my Turbo, Downpipe and Fuel Pressure Regulator fitted at ACE Motorsport.
Turbo i bought brand new for roughly £600

Being a 2000 V plate you don't need to buy an ECU, just get your existing one remapped (ECUTEK).

BTW i have a 2000 W plate with a VF34 and a Tek3, it made 312bhp at Powerstation, but had 2 dips in the power curve, which i beleive is down to a dodgy boost controller, so should be capable of a bit more, maybe 330.

For value of money and easy accessability i'd get a VF28, perfect for what your looking for as won't be over stressed or under used.
