Out of interest which of these turbos would see the most acheivable power gains.Ive heard the VF30 is one of the best IHI turbos for performance but is this a standard turbo or a hybrid? also how does the VF30 compare to the TD05

cheers

if you can get a td05 and get it front entry modded than alledgedly its smiles all the way.

the TDO5 is cheaper to buy, cheaper to repair, more reliable but spools a little later, it will hold much higher boost without exploding, oh did i say its cheaper

i would take a TDO5 over any VF turbo

Peanuts

I thought the spool up was only 500 revs further up the range max.

Andy.F

Less than that I'd say. VF30 2800rpm TD05 3100rpm ?

Howsit

How much is a TDO5 ???
How much is a VF30 ???

Thanks

td05's are getting rarer.
somebody keeps snapping them up!
then you need a front entry conversion, allow say £350 all in for a good condition second hand unit converted.
cant comment on ihi vf's but while the exchange rate is good why not have a look over the pond(usa).

Tell me this was Daren signing in incorrectly?

Yes Andy was me signing in on other name.Ive sourced a couple of cheap TD05s which im going to get the conversion done on

ScoobywagonGl

lol Andy there was me thinking i looked technical and you have foiled me
guess he knows i dont have a clue

Peanuts

was just worried you were about to undertake the mother of all conversions!!!

I have bad experience of VF turbo's - they are crap.........espcially the laggy ones that seem all too common from Turbo Dynamics....................

i.e. loads of lag and poor peak power........you know the ones..............

Wish I hadnt changed the td05/06 now........... just needs to have the exhaust side sorted to stop the surging...... nastiness

i have a TD05 thats been fully reconditioned, was goin to sell it for a VF30-34 but im now thinkin of sendin it to Andy F to get a F/E conversion done as ive been told the power gains are better from the TD05

What's the benefit of making a TD05 front entry ... apart from straighter air flow? Much improvement in airflow / torque / power?

How much work would it be to fit a FE turbo to a scooby with original 90 degree entry turbo ... I know Andy F supplies a 90 degree Samco to mate up with existing pipework for 05/06 20g turbos on these poor beasts ...
IIRC it means lifting manifolds etc?

Scoobcity Daz

well the TD05 wit 90 degree entry wont fit my 98 turbo, its needs to be converted to f/e to fit the car

Daz

Does your inlet pipework go under the o/s inlet manifold?

Mine doesn't !

Scoobcity Daz

it sure does, as far as i know on every engine after either 96 or 97 the intake went under the manifold

vulnax999

iTrader: (7)

Ohhh the joys of a MY94!

Scoobcity Daz

yeah, ur lucky there mate, the td05 will fit straight witout any conversion

vulnax999

iTrader: (7)

Yeah, bought a 96 TD05 prety cheap,( 90 degree inlet ) in good nic, dropped straight on!

Feel that boost now compared the to TD04 I had on me wagon! All the other mods were too much for the ickle turbo, now working well!!!!!!

Scoobcity Daz

yeah, im really lookin forward to gettin mine sorted and fitted, shud be kickin about 310bhp when in

vulnax999

iTrader: (7)

Very nice!

vulnax999

iTrader: (7)

Anyway,

As per my question - do the front entry TD05's perform better?

Scoobcity Daz

well shud be, a lot of work is bein done at the mo

Andy.F

Probably around 10bhp in it at the limit between 90 degree and FE on a TD05

Thanks Andy, was wondering, now I see it is just to fit in a TD05 to later cars .. hehe at last a benefit of a 90 degree inlet car!!
Does this drop apply to your 05/06 20G items too? with the "adaptor" samco hose for 90 degree inlet systems?

Not an answer to your question but some info for TD05 buyers out there.

I should be getting my TD05 back from turbo dynamics at the end of the week. Cost me 250 for the turbo from Grade-A (a bit much but I wanted one NOW), and then 150 for a recondition, so 400 all in (and then VAT) for a perfectly running TD05.

Can't wait to get it on my MY94 wagon which has a TD04 at present.

You WILL notice the difference - it is a bit later to respond when you hit the loud pedal ( 300 - 500 rpm later in my case with OBX tubular headers and big up-pipe ) but when it gets to boost, it GOoooes !!! Far faster than the TD04, albeit I have other supporting mods like STiV TMIC & undertray & I/C water spray, walbro fuel pump and reg, full decat exhaust with splitter, samco hoses etc.

But I had to change ECU Map to support it, as my TD04 map was overboosting and showing some det at 3000 - 4500 rpm ... TD05 map works fine, held 17 - 17.5 PSI, great once going!

I've got a VF30 on my 98 wagon. Not too bad a turbo, pulls nicely.

But, have been lured into one of Andys TD05/06's (again)
So the VF30 will be off if anyone wants to try it. (as long as they dont blow it up)
