Marts WRX

The turbo in my newly purchased MY96 wrx is shagged and needs replacing. The turbo on it is supposedly a VF22, but if I can't find a replacement will a TD05 bolt straight on without any issues or will I need it remapped to suit the TD?
- or -
If anyone could also point me in the direction of a decent conditioned and fully working VF22 for cheap, that may help me too.

Any info is appreciated, thanks

TD05 should bolt straight on, but make sure you have the correct 'entry' to fit your car. Some are 90° entry (additional elbow pipe) attached and some don't. Removing the old one will show what type you need.

Thanks mate. I'm guessing a remap is inevitable when changing the turbo? What turbo is better tho, TD05 or VF22? been offered both now for cheap, but overall cost is also a priority I.e remap cost etc. I might go for the straight swap of VF22, but will take your advice concerning entry angles. Thanks

Probably TD05 is better as you can run w/o a dump valve if needs arise. VF22 is a bit more laggy probably. I would go for a remap fella.

Like for like = no issues, different = issues.
Stick to what came out with what goes back in, saves time, effort and money.

Hmm you said supposedly? As standard this should have a TD04 therefore i suggest you check it>>>>

The obvious give away is the 90 degree bend which is an integral part of the compressor housing of the turbo. This will prve that it is not a IHI VF type turbo as they were all front feed.

My money's with a TD04 then a TD05 to be on this as standard.

Good Luck

Only a TD04 if its a wrx wagon, the saloon will still be a TD05
And the only subaru that had the VF22 standard was the 22B, they didnt waste the time or effort putting roller bearing turbo's on wrx's

Thanks Tony i couldn't recall if it was a TD04 or a TD05.

As stated, if a saloon, then the OEM turbo for a MY96 (reg'd on/before 31 Aug 96) WRX is a TD05H 16g. As also stated, the dead giveaway would be the 90deg snorkel intake. If you look carefully on the compressor cover you should be able to make out the turbo model code - just to make sure it's a TD04 or 05.... or indeed the 'wrong' VF22!

If you don't replace like for like, then a remap is a must. Even then, if it IS a VF22 and you replace with the same, I'd STILL get it remapped - as there's no telling whether a previous owner had it remapped anyway!, for that non-std fit turbo (if you get my drift).

Cheers guys. The scooby isn't with me at the moment so I can't check, but the guy who has it, and is going to fix it will take a better look by this weekend... Although he did say that it was a vf22 and not a TD05. I very much doubt the guy I bought it off did a remap since adding the "low mileage" turbo 2 months ago. I'll pass your advice and info on to my mechanic ( although he will already know that - hopefully!).

Really is a pain in the ****. I bought it on Sunday 8th November (my birthday) and by the 10th the clutch was replaced... Now Turbos gone. I've only driven it three times, and one of those was home from picking it up!

Still, better to have things go early rather than later when I'm skint eh lol

I can confirm the turbo is actually a TD04. MY96 first registered 1/9/96 going by logbook.

Just need a decent replacement now also needing to replace the oil feed pipe...

A lot of nonesense in this thread. I have an My97 wrx and have spent a lot of time finding out what turbo it should be fitted with.

Mart- If your car is a phase 1.5 (late 96) It should be fitted with an early IHI roller bearing turbo i.e VF22, VF23, VF24. If your car is a phase 1 (top entry) it should be fitted with a TD05.

As I said i have spend hours looking into this. When I bought my car it was fitted with a TD04 which I found strange given the year and what everyone else was claiming to have on cars of the same year, it was standard in every other respect allthough I got quite a lot of knocklink activity. I have recently fitted a VF24 and surprise surprise the knocklink activity has gone. I would urge you to look into this further before fitting a TD04.

Not nonsense at all!

OP categorically stated "MY96 WRX".

MY96 is 1st Sep 95 to 31st Aug 96, and assuming his car is a saloon, then the OEM fitment should have been a TD05. If a wagon, then a TD04.

If, however, OP's WRX IS actually a late 96 i.e. from 1st Sep 96 - therefore a MY97 and not a "MY96"! - then you're right: a VF23 or 24 and, I think, the VF22 too. Depending on what Subaru had in their parts bin seems to be the "accepted" fact (regardless of whether WRX/STi/saloon/wagon).

Precisely.

Marts WRX

Guys, I'm new to all this yea and I haven't had the car with me to look at. The car was registered on 01/09/96 (on logbook), but the turbo taken off was a TD04. Maybe I just have the same issue as Jonny???

jonny_693

I think whats happened is at some point in your cars life the turbo has gone and unable to find an IHI the previous owner has whacked a td04 on as a temporary measure. The car will work with a td04, just not as it should. They certainly werent fitted with them as standard from that era. I would get the fueling checked in case.

joz8968

Yeah, 01/09/96 is, allegedly, the very 1st day of MY97! so, as said, it should be fitted with a IHI VF22/23/24 (can't remember which). Even if it was a late MY96, then it still should have had the larger TD05 (that is, assuming yours is a saloon?!) - so you still have the 'wrong' turbo on, whichever way you cut it!

Jonny's hypothesis is no doubt correct and, as he said, get the A/F ratios checked, as you have no idea if the TD04 has been mapped! If it hasn't been mapped, then it prob helps that it's a smaller turbo in this regard, as it flows less air for any given boost level, therefore the larger VF (or TD05) turbo's existing, rich, fuel map means the AFR could be on the safe side of things...??? Which is nice.

Is it an import or have you just assumed it's a WRX and is actually a UK car ?

joz8968

iTrader: (13)

Very good point! ^^^ A MY97 (and MY98) UK Turbo 2000 AWD car would indeed have a TD04... FRONT ENTRY! (i.e with NO 90-deg intake 'snorkel'; just a circular intake mounting 'collar').

Check the car's VIN... if it has a "K" as the 6th digit in the 7-digit 'Applied model' code, then it's a UK car. Another check is, does it have "Bright" button on the centre dash console? (unique to non-JDM cars).

Marts WRX

The car is back with me tomorrow morning guys so I'll check properly then, but as far as the history I have of it shows it's an import. The turbo taken out was a front entry td04L and the one I am having it replaced with tomorrow is a TD04L. It is also having the fuel checked too.

As jonny said, it's probably been replaced with a TD04 earlier on in it's life. It works with the TD04 on it, so for now it'll do. And when money allows, I'll replace it again with the 'correct' turbo.

joz8968

Sure.

But if you get your TD04 mapped, then obviously the AFRs will be okay... AND... you should be producing IRO 280bhp! (if you also have a decat system - and Walbro pump to be safe).

So, UNLESS YOU WANT MORE than that sort of power, then I'd stick with the remapped TD04 anyway!, as it'll be the quickest spooling "up to c.280bhp" turbo option out there (at the expense of a weaker pull to the redline). But its 'instant' response should prove very useful - and exciting! - on the road, in real-world overtaking situations.

After all, the std MY97>on JDM saloons are 276bhp cars anyway... BUT... produced on the bigger, slower spooling VF turbo. But, that said, the VF22/23/24 can all be mapped in excess of 320 though (swings and roundabouts, etc...)
