Turbo options

Has anyone heard of or tried a Garrett T28 hybrid turbo as recomended by turbo technics , apparently it will take power upto 350bhp on a T5

I ran T28 hybrids on my Rover and Nissan and they are a good blower !

But to fit it to your T5 you would have to have your manifold machined for it to fit.

And it wont be a 350hp bolt on you would need a decent custom re-map to make that work.

True it can flow enough for 350hp but so can a 15G if you know what your doing

Thought about a replacement in the G range lance. I know they do up to a 20g which i will assume has the same characteristics as my turbo but with the ability to take more boost !?!?

I am cocidering a 15g looking at what Mrs Mopps and Bracers can do !
Do like my 16 t but would be intrested to see what torque and when it comes in and tails off as a comparison to the 16t,
I liked the low down grunt of a 15g but I like the flat out high reving of the 16t!
I dont know what to do for best!!
Il probably stick with a new 16t when the time comes!

Broaden the spectrum and get the 19T - you know you wanna

Yep, that's the way to go!

Just been on the motorway with boostgauge on consitantly holding 0.95- 1bar and was spiking around 1.1-1.2 briefly when road cleared and foot went right down then back to around 1 bar, So how much for a new 16t and how much for a 19t?

You have to remember Lance that with the 19T you'll need a new remap too!

16T cheapest option then by a good 800+ I bet

Lance, you might not actually need a new turbo. First find out what the problem is, and if it's the turbo, thats the time to think about turbo choice.

Also, 19T remap for existing RICA customers is only £100 + VAT.

See ya Thursday for check up

not up on turbos here whats the difference in them apart from spin up times?

There size is only the visual difference between the turbo’s, its the characteristics of how quick they spool, how much air they can flow, and at what engine speed can they sustain that pressure.

Below I've put some of the spec together for the 4 main turbos, including there rated flow rates and a compressor map.

Turbo Type = TD04HL-15G

Rated Flow = 428 CFM

Compressor map

Turbo Type = TD04HL-16T

Rated Flow = 435 CFM

Compressor map

Turbo Type = TD04HL-18T

Rated Flow = 488 CFM

Compressor map

Turbo Type = TD04HL-19T

Rated Flow = 500 CFM

Compressor map

And here's some more.

Still looking for the missing data on the 18T sorry.

So what was the prob ?

**volvotuning** · Thursday 20th January 2005, 17:09

Actuator was at 2psi, so that was fixed at 4 psi. Boost control solenoid was also faulty. Turbo is probably past it's best, but not worth changing yet.

Turbos still worn but not knackered , slight adjustment to waste gate and a new boost control solinoid and some carb cleaner and she holds 1 to 1.1 bar instead of 0,9 bar with the occasional spike and unsteady uneven boost.
Adam and Hamish reckon shes producing around 280-290 bhp.
Still the turbos past its best but not knackered yet so should get atleast another 6 months 10k+ before i have a real need to replace it!
She definetly feels a lot more urgent now!
