Hi Mike
Have sent you a pm

 

Replied back bud

 

Bump

 

It will be easier and cheaper to find vf34,35 or 43 ( all capable of 350bhp and decent spool).......you can always upgrade them to billet wheel for quicker spool and more flow.

 

the turbo is not for going on a subaru its for a seat leon 1.8t and i know vf34 is a good turbo but its maxed out around 340 and not sure what the vf35 and 43 are like on the 1.8t

how hard is it to upgrade the wheel to billet??

 

Once you got the right wheel its oreatty straight forward job......just get it ballanced.Billet versions should make 370-400

35 and 43 are similar to 34.

I imagine on 1.8 you will struggle to get full boost at 3k.

 

would i need a rebuild kit? and has anyone done this?

 

You are only changing compresor wheel so you dont need rebuild kit (if turbo is in good condition to start with). Company that will balance the core can surely change wheel for you

 

How reliable are the vf34's ive been told the bearings aint very strong...

 

All mentioned IHI turbos are reliable (especially if you manage to find low milage unit.....vf43 tend to have less miles on them since they are newer).

If i were you i would check td05 16g"s from Evo 6 to 8 or 9s 80 series.If you get td05 get one that is twin scroll (you will have to fabricate exhaust any way and some even came with titanium compressor wheel/TME VI) as they will more or less all offer 380 - 420 bhp with minimal lag

 

The manifold i have fit subaru bolt on turbos so a evo twin scroll wont fit
or can the exhaust housings be changed to fit a ihi style?

 

That cant be done as evo turbos have completely different layout.IHI twinscroll would be possible with some mods to up and down pipes (different flanges).

 

sc36 then that should be quick spool...right?!

 

Not much faster than vf34&35,but much harder to find and will cost more
Buy one of the IHIs and see how it performs.If it will be to laggy or you need more power you can always upgrade compresor wheel later on

Prices for mentioned vfs are from 250 to 350 and billet wheels are around 140

 

ok sound...what is the quickest spooling turbo of the ihi22-48's?

 

If you take twin scrolls out of equasion than it would be vf34 followed by vf 30/35 (300-500 rpm later) but 30/35 is easier to find.Vf 43 would be laggier but its easier to find low milage unit

 

are the vf 23 24 28 laggy?

 

They are old design turbost so vf30+ is supirior in spool.

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 scrollalso 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.
