Your Zero Sport turbo is probably based on a VF28 or one of these derivatives. The one I fitted to a P1 recently did 351 bhp and 335 ft/lbs from memory and spooled to 1 bar in 4th at 3,200 rpm or thereabouts. The car had 550cc injectors, ported headers and FMIC.
I think you need to start by finding out why you lost compressor blades.
If you want to go a step up from the Zero sport you could talk to Scoobymania or AET Turbos amongst others.

 

was boosting to 1.5 bar at 5500 from i bought it 7 months ago freshly imported so you recon its a vf 28 i seen a list of the vf series specs measurements and that stuf and it didnt match any like i said just wana no what it would be or be similar to so i can get the same or better or could you recomend a turbo that would suit not sure exactly what has been done to the car bar from fm boost controler bigger turbo full 3" apex power fc and its a sti ra v-ltd realy wana get it back on the road as soon as poss so any help would be greatly apreciated thanks was looking at a vf 34 wot would your views be on it?? ta

 

It could be VF22 based which would explain its fragility

cheers

bob

 

VF34 would be spot on btw

cheers would this be any good or a piece of ****??? SUBARU WRX IHI VF34 Ball Bearing Turbo (Free Shipping) on eBay, also Engine Tuning Parts, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 27-Apr-08 04:30:39 BST)

 

infact what would be the better choice tdo5 18g or a vf34?? thanks

 

As long as you are sure they are selling genuine product, and not cheap Chinese crap immitations.

Sometimes its just better to buy second hand, or new from known reputable sources.

 

how do you no if its genuine??
cheers

 

Thats the problem. You wont know until it dies a few weeks/months later lol.

It was a massive problem a year or 2 ago. Not sure if its still such a problem out there in ebay land.

 

they give a 3month or 10000 mile warrenty should count for somethn no??

 

It should do, of course....

But it will need returned to Japan for any warranty claims no doubt, then add hassle/cost of removal/refitting.

There is a good chance it will be dead on.....but for an extra few quid. I think I'd prefer to buy peace of mind from a known source.

 

Zero Sports turbo is a VF28/34 with a larger compressor wheel.

Remember you need to add import duty & VAT to that price. I would also be a little weary of a 7 day return policy

 

cheers its the blades on the front of the turbo that have broken off are the turbos fixable ?? and what sort of doe you talking if it could be fixed it would it mean it would save me getting it maped ?? cheers

 

Braking blades off "the front of the turbo" is pretty serious.
What caused this?
Injestion of foreign object or excess turbo speed and turbo stall?
The cause of the problem needs to be identified or it will probably happen again.
The VF core that you have is supposed to be a sealed unit. It would be necessary to strip down and inspect the turbo before a sensible decision could be made on repair which may involve a complete new replacement cartridge which is not cheap and will depend on the actal cartridge in use on the Zero Sport.
Subject to repair cost you may be better to put the money into another turbo. If you want the turbo inspected, drop me an e-mail.

 

cheers dont no how it happened the car has been driven hard before but at the time of it happening it wasnt it has a induction kit no signs of anything being able to enter and dammage the turbo also where would these bits of broken blades be right now ?? thanks

 

If you are lucky, the compressor blades are snagged up in your intercooler and hopefully they have not passed through your engine. If the exhaust turbine looks OK they are still in there and finding out they have travelled through the engine should be a priority. If you have been lucky and there is no major engine damage, the chances are you need a replacement intercooler.
What boost have you been running?

 

exhaust turbine looks fine god this gets better every day is it not possible to get them out of the inter cooler if they in there car was running 1.4-1.5 bar it has afront mount hks wouldnt like to think i gota replace it also eek cheers
