I'm looking for someone or company that can rebuild my old turbo as the bearing has started to whine badly,,, can anyone recommend a place and what sort of prove this would cost? Im located in Somerset

 

http://www.stage-infinity.com/2007/0...turbo-rebuild/

 

Just buy a secondhand one for about 50 quid, job done

 

As above - 10 a penny

 

Am I right in thinking that some run on a bearing and some are like on a oil slick?,, as I brought a spare one but seems to take awhile now to spool up?

 

They have plain bearings which need a film of oil between shaft and bearing.

 

if the new one is spooling slower i would check for zorst leak,

 

+1 for the above, no point rebuilding an old when there are loads of td04 's out there.

 

Just make sure you buy the right one for your car as there are front entry and side entry td04s. Will depend weather your car is jdm or uk.

 

If your car is 92 -96 and a uk it will be a top entry td04, 97 onwards is front entry . They never fitted td04's on early jdm cars only the wrx wagon all the rest had td05's .

 

o dear, busted turbo, 'sorry hunni but a new bigger one costs the same as a replacement' lol

 

well i took the turbo off and a mate had a spare one kickin around..but oil return was at a slighty different angle

but i couldnt see it saying td04 on it..instead on the info plate


it says turbo spec--- vf28

is dis still a td04 then?

as one im runnin now is loads slower and doesnt pull as hard compared to the one above i was running

any one with any info

 

VF28 is a totally different beast to a TD04 which means the cars been remapped to suit or you have something different to a bog standard UK impreza.

What model/year of Impreza do you have???
Always useful to mention in your posts or include in a signature.

 

its a 99 uk turbo..been through all paper work and nothng to say about bein mapped etc...its de-cated..dump valave sameco hoses..still run tmic and everything seems standard..runs about 1bar on boost..

that is the sti turbo then?

 

It's one of them...........

 

If you have taken off your std td04 and bolted on a vf 28 then your car is not going to run right without a remap. Your ecu is a E3 and is set to run a td04,as said above the vf28 is a larger turbo which when it is mapped to your car offers much more mid/top range than the td04. If your car has been mapped / or not it still needs the std turbo fitting .
There plenty of td04's kicking about for silly money, in fact I have a mint one off my 00 car at my mums if your interested.

 

Midnight, the way i read that, he had a vf28 already fitted when put a tdo4 in its place hence the lack of performance.

 

I think he says td04 rebuild at the start of the thread which would suggest he has a std td04 fitted,and the new turbo he has put in says vf28 which would also explain the lack of performance, as his ecu is fuelling for the smaller turbo.
I had a BRAND new td04 fitted on my 99 car and it started spooling at 2300 rpm, the vf28 I have on my current 00 car starts spooling at 2700-2800 rpm

 

This would suggest a td04 which on a 99 car runs 0.9 bar

 

Well after doing some home work I was toldy car would run a td04,, hence that was what I thought it was,,, but it a vf28,,,, the car ran fine with this on just the bearing had gone init,,,

So what would u guys recommend now?

I liked how the car performed with the vf28 turbo on it,, but I'm not sure if the car is mapped etc,,, for it (but always ran fine with it on)

Where is best to get it mapped? And is there anything else I need?

Or just keep it stock with the td04??

 

You need to find out one way or another if the ecu has been mapped as if it has then you will need to put another vf28 on. Maybe the previous owner just bolted this on as ,a vf28 in its std form will pull 1.1 bar+. If the ecu has not been unlocked then bolting a td04 on will be fine. A vf28 will run if it is bolted on , but you wont know for sure if it is running correctly until a specialist has looked at it. For mappers try Simon (aka jgm) or bob Rawle , or andy forrest who are 3 of the best in the business imho.

 

Well It would only pull a bar with the vf28 so would that mean its mapped If your saying it should boost more than that ( sorry I'm not with this mapping stuff)

I would like to upgrade the turbo has I think the td04 is pretty weak tbh,,, but as I need the bearing done on the vf28,, is there any other turbos that would recommend? I'd rather have it low to mid range rather than all top end power,,, as sometimes it's cheaper to get another turbo than a rebuild and if the car has to mapped then that's the time to do it

 

pull the carpet up on passenger side,unbolt the metal cover and have a look at your ecu and see what youve got. only need to pull 3 plugs on the ecu and you can take it inside and take off the cover and see if its had a chip etc fitted or is a mappable ecu of some kind.

 

Ok I will have a look, what sort of mods need doing to hit 280 mark? Or which is best

 

td05 would be a better turbo for a start. 3 port boost solenoid, decat and turbo back exhaust, 440 injectors, i think you have the later spec map sensor so you can raise boost levels. some sort of ecu management ie esl board or apexi ecu and commander , ecutek or syvecs. maybe adjustable fuel pressure regulator as well? theres no way of guessing what power it will make, thats in the hands of the mapper and his skills at getting the optimum power at a safe level.

 

Ok so it's best to look out for the above parts then tbh,,, thank u for that,,, first il look at my ecu and see if it's stock or not

 

Interesting, I was under the impression that the 92-96 UK saloon cars had a TD05-16g as standard?

 

My99

 

MY 99 car should have a E3 ecu which should have either a red or black label label on the casing. Failing that it may have a Y7 which is off a 00 car. There is no point opening it up because you cannot tell if has been mapped by looking at it. If it has a aftermarket ecu then that might explain the vf28.
A td05 is a stronger turbo than the vf28 due to its sleeve bearing, but it does not spool up as quick as the vf 28,which is one of the fastest spooling turbos in the vf range. With good supporting mods as listed above both are good for 320+ bhp.

Sorry mate you are right td04 was std on the sports wagons
