Absolutely - yes - Turbo Dynamics can supply lots of turbo options for the 16vt

hi i was really looking forward to seing rough specs and prices and characteristics, ie how hybrid stage 3 compaires to gt28,s and billit/gtx gt30,s, i was woundering what for me would be the ultimate turbo,

i am running a stage 3 set up with the usual saporting mods just now but wanted to know how much it would cost me to upgrade for my dream turbo (without going forged) so i could get the amazing top end madness of gt30 but still having early spool up with strong bottom and midrange if there is such a thing or how close i could get to these characteristics.

Well if you want "amazing top end madness of gt30" tehn you will need to be forged or blow your engine if not.

Anyway, I dont know if all the other people above have heard back from Matt at TD, but I know I havent, and I messaged him over a week ago.....

Haven't heard back yet either, i imagine his inbox is pretty full.

Have a word with Flea, he'll be able to advise based on your wishes and current spec.

I've not heard anything either.

Hi Guys,

Sorry for the delayed reply, we had some staff absences recently and haven't had a chance to get on here! All pms have now been answered, apologies for the delayed reply.



As is the nature of these rebuild prices they can fluctuate slightly depending upon the condition of the turbo sent in for the work to be carried out but below is the prices if the unit sent in is in good condition with no major issues:

1) 60 trim compressor wheel, 360 thrust kit & stagger gap turbine end piston ring - £350.00 + vat

2) 62 trim compressor wheel, 360 thrust kit & stagger gap turbine end piston ring - £350.00 + vat

3) As above but with the Pulsar T28 shaft and modified housing to suit - £475.00 + vat

Matt

have to say that those are pretty decent prices for anyone looking for a hybrid

a quick couple of technical questions for you Matt, one related to the above, the other not

Garrett have just released the gtx28r with a 60mm 58 trim wheel, how would this wheel perform in relation to say either the 60trim and 62trim wheels more commonly used and would it be able to be fitted to a hybrid

are the new billet wheels providing much in the way of increased response and performance when run at moderate boost levels, i.e. 1.2bar or do thay only really show there true performance increase over the stock gt wheels at higher boost pressures

and on a completely unrelated note, what do you think of the borg warner efr series turbos, are they as good as they are hyped up to be particularly in terms of spool time with the titanium alloy turbine wheel

cheers

At present the Garrett GTX billet compressor wheels are not available as seperate items (indeed that is likely to be the case long term). The smallest wheel in the GTX range is the 63mm item which should far outflow any of the previous T25 60mm compressor wheel.

This may come as a surprise but the Garrett GTX compressor wheels are actually heavier than the standard cast wheels (by upto 10% in some cases). This makes sense when you consider that billet is heavier than a piece of casting (next time you're in a petrol station pick up an Aero and a Yorkie - see how they compare!). Garrett initially offered the GTX turbos with the same size (give or take) compressor wheels as the cast items - these were never going to be lighter and this showed in testing where they responded similar low down to standard cast wheels - the difference came in the elevated pressure ratios they were capable of holding meaning greater top end was theoretically possible. They also felt stronger in the midrange due to broader compressor map. In other words you had to drive them hard to see the benefit! The new generation of GTX compressor wheels are designed along a similar method to our own where we make the strength of billet work for us - wheels can be machined thinner and material removed in key areas meaning you can essentially have a smaller wheel that flows the same and is stronger than a larger cast item. This is the benefit of billet wheels, smaller wheels that flow the same as larger ones rather than like for like swaps 'because it's billet and therefore better'.

I can't wait to see the EFR range break into the market - we have been appointed the sole UK approved dealer of the product by Borg Warner and the pricing is very good. The Gamme-Ti turbine wheels really are very light and this will make a huge difference on the road giving superb response. Should give some other turbo manufacturers something to think about! All we need is the stock to hurry up and arrive...

Matt

thanks for the informed response matt, interesting reading, should be really interesting seeing the results of some of the efr turbos when they start being fitted to various vehicles

Will that mean if you own a GTX and the compressor wheel gets damaged you have to by a new turbo? Your own can't be repaired?

You'd have to buy a complete CHRA (same as if the turbine wheel was damaged on any of the ball bearing product) which, unfortunately, makes up most of the cost of the turbo so isn't cheap!

So what about Turbo Dynamic's own billet wheels? Can I replace a wheel or modify a turbo fitted with your own design?

We are happy to fit our own design wheels to turbos so that's not a problem, our wheels won't be interchangeable directly with the Garrett GTX items (and the performance between the 2 may differ slightly) but I'm sure it's something that could be sorted with a little machining should the need arise!

About the EFR range, I saw a while back the results of a EFR7670 on a Misti Evo, where they were running a T4 1.05A/R on a twin scroll, that produced 582bhp and 583lbs and had 2.5bar by 3600rpm ans was still a 2.0!

that is incredible figures from a 2l engine

they are nice prices indeed.


are the details of pulsar T28 shaft...etc refere to the 76 trim turbine wheel turbo?

does anyone run one of these turbos? or are these turbos what we on the forum recognise as the stage 3, 350 bhp turbos or are these more powerfull?
What would the estimated max bhp be?

Im not exactly savvy on the turbo jargon and technical side of things but I am looking at upgrading and reading up on turbo specs on this forum gets very confusing as each supplier has different spec for the same "stage 3" turbo. yes I have read the hybrid turbo thread, still clear as mud though.

The 62 trim comp and 76trim turbine are known as the FC Performanace Stage 3, or CR Turbos stage 2, and have been mapped with supporting mods to circa 350bhp.

thanks for clearing that up. Wheres my PPI claim money, I want one now!

I have a 97 20vt with a few mods but nothing too serious (new cam and chip). I have a spare standard turbo which I'm considering sending to you for either option (1) 60mm trim wheel or option (2) 62mm trim wheel. I'm unsure which to go for as I'm no expert on turbos. Is the difference between the two their spool up rate? Will a 60mm gives you a power band lower down the rev range ?
Or do I have the wrong end of the stick/turbo?

Second question :
Do TD buy back used turbos? If I send my spare to you to get rebuilt when I swap it for the current one in the car can I send it to TD for a refund? If so how much do you give for a standard OEM turbo (Garret T28).

I did send a PM but got no reply, maybe TD were shut for easter hols though.

Shaggy, spool up will be virtually identical between the 62trim and 60trim wheels

I would go with the 62trim wheel as it will flow more air and therefore produce more power and hold boost slighly better higher up the rev range

power bands for turbos with each wheel will be very close although you will get slightly more at all points with the 62trim

if you go for the 62trim wheel and retain the standard turbine wheel get the wastegate ported

OK Cheers for the advice Doug. I'll go for the 62 so.
TD are you there?

Matt tends to be busy, but I'll mention that there's a question for him

Sorry we were closed for easter and now have a mountain of work to do! I have sent a reply to your PM but if you need anymore information please let me know!

Matt

Assuming, you will receive a used turbo in good/normal condition and modification specs are clear, how long does it take until I will get it back the turbo ??

Thanks,
Jochen

Just a quick update on the great service you can expect from TD

My car has smoked from the time the new turbo was fitted, so this week, Motormech removed it, TD collected it and they've just spent three days doing all sorts of tests and measuring to make sure its OK. Turns out its absolutely fine (and thus my smoke is still a mystery), but I don't imagine very many turbo dealers would be so accomodating

10/10

good to see forum, member, and company relations.

Havent heard from TD for a while are they still about on the forum or to busy?
