Anyone running a TD05 20G?

[Johnny-C]

Hello all

Wondering is anyone running a td04 20g,either on a 4e or 5e?

Would like to know your thoughts on lag,spool times etc.

Im looking at one of the blouch items with billet internals,not sure on ball bearing or journel as they have 2 types.

Thanks

There are a few people using them I think, spool isn't that bad but obviously no ct9 lol full boost by around 4k iirc and good for upto around 350 max.

Thanks for that.

Blouch rate theres for 450 and 470bhp.

Maybe on a 2litre Subaru but at 2 bar +, we're on 1.3 starlets with no where near there boost levels

Depends on the build though.

Anyway,so is/has anyone ran a 20g??

[RobSR]

Burwash ran a td06-20g. A td05-20g wouldn't be tooooo bad imo. 1.6bar by around 5k id imagine.

im running a TD05 18G (billet wheel)

starts spooling at 3k and full boost 4,5k mad at 1.7bar!

Anyone tell me how to find out the compressor wheel size? I dont see any 18g/20g etc stamped on it

[Ryan_EP82 GT]

On a td04 by the way

[jayc-glanza17]

got a compressor map?

would help to know better..

[AdamB]

A lot of aftermarket turbo manufacturers don't offer compressor maps for their custom spec turbo's because it becomes easier for their competition to copy and try to better what they have already produced.

[jayc-glanza17]

Ok. How much larger are these compared to a stock td05-16g?

[RobSR]

16G comp. wheel iirc is 48mm / 68mm

18G comp. wheel is 50mm / 68mm

20G comp. wheel is 52mm / 68mm

Inducer/Exducer

Don't hold me to that tho haha.

[jayc-glanza17]

so lag will be same, so actually would be ideal then..

although im toying with a v-band garrett gt28 set up

[RobSR]

Well no a 20G will have more than an 18 and 16G.

The billet wheel'd equivalents will be less laggy due to lighter comp. wheels.

What GT28 were you looking at?

[AdamB]

The problem being though if you switch to say a 20g you could end up shifting the restriction to the turbine side, so no matter how big you go on the comp wheel your going to gain very little power (due to the turbine side being restricted) and much more lag because of the extra mass of the comp wheel.

[Johnny-C]

Thanks for everyones input so far.

Im torn between a td05 18/20g (as I already have a td series turbo kit) or a gt28/30 series turbo.

I thought about a td06 also,but its quite large!

[gorganl2000]

i'd forget about the td06 idea unless its a dedicated drag car

[RobSR]

Depends what power your after and what you want to use the car for.

I don't think the lag on a TD05-18G is bad atal and you can hit about 350.

GT28/30 depending on what spec is going to make you a lot more lol!

[jayc-glanza17]

Bang for buck td series.

Ive done a little more research and 18g

Appears to be favored for street, track car

High revs its the 20g.

As you have a td turbo kit cheapest option

Is td05 18 or 20g.

What is car for? Track and occasional track use or street?

[Johnny-C]

Thanks fellas.

Im not sure what ill use the car for,mainly road and drag,the research continues!
