I'm upgrading my wrx and trying to get hold of a vf34 with out much luck, but keep coming across the td05 which is half the price and a direct replacement so wondering why the price drop and is it a turbo suited for the mid 300's bhp i'm after. thank you

have u considered the ihi vf35?

richard1522

iTrader: (2)

I the JGM said about that turbo but to to be very honest i dont know the difference between any of them and i cant find any thing to compare each turbo to one another. I am new to the whole upgrading and want the car to be the best so trying every path i can. would the vf35 be a good option??

Rob Day

iTrader: (78)

In a nutshell, its a capacity restraint.
The TD04 dies at the top rpm range, but it does spool very quick so is good for low rpm power.

The TD05 & VF30 takes a little more to spool but is harldy notciable, but will keep pulling till the redline.

I recently bought a genuine TD05 that had covered 150 miles for £165, but the following day found a brand new VF30 that had never been fitted for £150.... So a bargain was then installed and the power is excellent once mapped. I sold the TD05 on here for the same money.

You should get a good price on here mate, do your home work and watch the fleabay garbage, some are china copies!!

I'll keep an eye out for you - what power are you looking for and supporting mods have you got/getting?

Rob

richard1522

iTrader: (2)

Thank you rob its very much appreciated.

I havent got any yet but in the process this week of purchasing..

pink injectors

full exhaust system

walbro pump

and hopefully a turbo to do the job with the mods i'm making.
i'm hopefully looking for the 330-350 range if poss but want to do it right if you know what i mean.

Rob Day

iTrader: (78)

I know what you mean mate

99greenwagon

iTrader: (39)

i went for a vf35 and have no regrets at all,this turbocharger has good early spool with very little lag and can produce about 350bhp.it drives perfectly smooth and the power is progressive.

99greenwagon

iTrader: (39)

it also pulls right up to 6k

richard1522

iTrader: (2)

thank you for all your replys.
If you were in my shoes out of the vf34,vf35 and the TD05 which would you go for?
oh i also plan for a FMIC in the not to distant future if that makes a difference?

Rob Day

iTrader: (78)

FMIC - for the power your looking at I here theres no point, here mate this is my recent thread:

the vf 34/35 are almost identical units,dont know much about the tdo5,the vf35 are easier to track down and quite abit cheaper than the 34 as there are more good secondhand units available.

Hijacked this mate from another thread:
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
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.

PE 1818 The 1818 supposedly comes on boost extremely fast...which make it great for road racing or aggressive driving (remember to be responsible :^). The 1818 maxes out somewhere between 350-375 hp.

PE 1820 The 1820 is larger than the 1818 and is capable of running more boost, but at the expense of more turbo lag. Expect it not attain full boost until you have passed 4000 rpm. However, it can be tuned to 400+ hp.

Fair point. It sounds you have done the same sort of thing as i am after. The fuel pump lateral have still got on offer and ringing them tomorrow or as soon as they are open to order. plus got to speak to japspeed about the exhaust and what i can do to get the least resistant but still pass the mot.
Are you happy with the results you have gained?
and am i going down the right path?

richard1522

iTrader: (2)

WOWZERS!!!! thats what i have been looking for!!! Your the man lol.
So i guess in a nut shell for me running 300 odd horses the vf30,vf34 and the vf35 is basicly the same. so i any of them would be ideal.

iTrader: (39)

u wont regret the 35 mate,its a great turbo. and u can easily pick up a low mileage one for about £250-300.

Rob Day

iTrader: (78)

Me personally >
The mrs > lol she doesnt understand.

If i was you id speak to harvey on here for the injectors, then you know what your getting. He supplies flowtested and matched, and cleaned so they are mint.

If i was you id follow this rule and fit all at once for around 330-350bhp. No point fitting parts in stages other than the fuel pump.

Walbro £71 delivered
STI Pinks £200+ (£220 max)
Uprated Panel filter £30 max
decat turbo up pipe £80 max
Full stainless 3" £200 max
Turbo (TD05 or VF) £200 max
STI Intercooler £160 max
Mapping £300 Plus

Budget - £1300+ labour

Reason i budgeted for you in my honest opinion is because unless you 'love the car', its not worth spending more on it becuase its not an STI, just like mine mate. The brakes and suspension etc will be next on your list, so then you may aswel have bought an sti and saved some money. HTH

Rob

richard1522

iTrader: (2)

HAHA funny you should have budgeted like that cos i was looking at £1500 for it all and very true about getting it all done at once which i intend to as soon as i can source these parts oh and a 3 port solenoid.

I have a VF35 for sale as I have upgraded to 20g. Its in really good condition and has no play at all in the shaft. £300 if any good to you.

Hi Richard

Any of these turbos will hit your power targets:

VF34
VF35
VF30
VF43
VF48
TD05 16G

Match that with a full decat, walbro 255 pump, sti pink injectors and preferably an STI TMIC and you will have a solid 330bhp or therabouts (depending on the turbo).

Out of that list a VF43 would be my choice.

Speak soon.

richard1522

thanks fella i havent heard of a vf43. you lot on here like baffling me with bulls**t lol

oh ok that shouldnt be to hard to find then. I have your number but went straight to answer phone i'll give you a call later mate if thats ok cos i need to run through a few things before you come down and map it. cheers

It'll pull further than that if you can let it breathe a little more. Mine pulls to 7600 and thats only because the limiter is there.
