TD06-17C on RB20

[Ed G]

Hi,

Just wondering if anyone could shed some light on how a TD06-17C with 8cm exhaust would perform on an RB20?

Thanks

Ed.

If you are intrested (or can read them-I cant!)

Edit : Just realised this map is for the std Mitsubishi item, the turbo I am looking at is the Trust item

Since i doubt anyone has results to post, to get an idea...

The TD06 describes the turbine, so has a similar exhaust wheel to my TD06-20G. Similar because i think mine has the TD06SH wheel which may be a little bigger then other TD06 turbines.

The 20G v 17C refers to the compressor, so the 17C is smaller, so less inertia meaning better response. You have the 8cm housing me the 10, so again you would expect better response.

Im getting 17psi at about 4,600rpm out of a completely std RB20...and making 222rwkws pretty easilt out of it.

So i would suspect (im guessing, dont know any better then anyone else, but a feeling from the resutls im getting) that you wouls be able to make 15-17psi by 4,000rpm and able to make 210-220rwkw with a good tune.

Looking at tunes as being conservative / normal / aggressive ... then im told my tune is pretty conservative, so with a more normal tune id expect to see the 200rwkw mark at 15-17psi...which for a street RB20 is plenty:)

If you are getting it at the right price and its in good condition, and is internally gated with T3 flange, then it could be a good thing.

Worst case scenario if you are inclined to get it, if it turns out it dies or your not happy, then with the TD06 turbine and 8cm housing with 360deg bearings, when you get it rebuilt you can easily get it hi-flowed using the 20G compressor or better again a later model Garret wheel:)

Some things to consider that you perhaps have not already thought of

Thanks for your reply Roy! Yeah my target is 200-220rwkw (would be happy with 200!) so this seems to fit the bill.... and the less lag the better...

The price is good, it's a direct bolt on, internally gated.

15-17psi by 4k sounds good to me...

The worst thing will be waiting for it to arrive !

Thanks for the rebuild option! I never thought of it that way, and it's a great option... tho will the internal gate struggle to control the boost?

Dont know, so may ppl say internal wastegates struggle to control boost?!?!?!?...so ok they are a cost and packaging compromise, but on an engine making 200rwkws (ie RB20) i dont think you will haev too much in the way of boost control problems, you arent talking massive amounts fo airflow...

[Ed G]

I just read somewhere (lost the page already ) that the td06-17c is maxed at 230rwkw !? does that sound right?

will it run out of breathe by redline?

I've driven an SR20 (GTI-R) with a TD06SH-25G 12cm external gate setup and it would have to be the fastest car I've driven. absolutely insane. There was another GTI-R with a smaller trust turbo kit on it, that came with dyno sheets showing 312ps at all four, the 25G equipped one was miles quicker so I'd say 350hp at all four+. I think if you are aiming for up to 200rwkw this will be a good choice, after that you may require something bigger.

I have been reading up bigtime on this turbo, it does not seem that this is a Trust turbo... can anyone confirm?

edit: I just found a listing on the CAPA website listing this as a trust turbo :confused:

[Ed G]

Ok so I'm thinking of getting either this turbo or a RB25 turbo.

What is leading me to spend the extra $$ on the 17C is the steel exh wheel, this seems to be the single most limiting factor of the RB25 turbo.

Or am I barking up the wrong tree seeming it only has the 8cm exh housing? This seems to be the limiting factor of the 17C......

Any feedback?

[Roy]

I have the 10cm housing on my 20G...my opinion go the 8cm housing!

Look up the Taka Kaira (spelling?) Jap parts website, their Trust Catallogue is pretty comprehensive.....will eb able to find out for sure whether the 17C is a Trust turbo (or just plain Mitsubishi) and what cars they recommend it for.

The 25G on a RWD car are good for between 280-330rwkws, so i think its a little oversized for 200rwkws on an RB20, so would be the TD06-20G. I think the 17C woudl be fine if had at the right price
