Hi i bought a td05-20g from here but when i had it mapped by andy f it didnt make 1bar till 3700rpm had someone look at the turbo he said the exhaust housing was bigger than the td05 looks more like td06 mods are
2005sti
Turbo
650 injectors
Aps innerwing kit
Full 3" decatted
Hrc fuelpump
Ported headers+uppipe

 

Whose up-pipe? Harvey's trick ones give lower spool.

 

Not a harveys one just my own standard headers and uppipe

 

lower spool as in quicker?

 

Yep.

If spool is a problem, talk to Harvey, he's a mine of info.

 

cheers will do.

 

Its more how do i tell if i have td06-20g instead of td05-20g

 

did a bit of nosing around and the td06 has a bigger garret compressor wheel fitted which might make it a bit laggy but it said it was a 400 bhp turbo. what did it make?

 

Forgot that bit 396bhp

 

sounds like it might be a td06 then bud as ive read the 20g is a 360-380 bhp turbo and the 06 is more a 400 bhp turbo like the figures yours made? but they both have bigger housings so that doesnt help in identifying it!

 

Cheers mate really pleased with the power once it kicks in

 

i dont know if this will help but im running a tdo5 20g and mine is 382bhp but an andy f 20g will make over 400bhp, i think the best way is to measure the inernals or send it away for an examination

 

Dont really want to take the turbo off as its my only car and daily driver

 

Stick a set of ported headers on and up-pipe, will really help with spool. You will need a map tweak though unfortunately.

 

Cheers matty and i see your cars running better now

 

Yep, yesterday was an absolute nightmare. I was soooo pi55ed off with it I could of quite easily set fire to the bloody thing,,lol...

All sorted and running amazing again now though.

 

Glad you got it sorted

 

TD05 is smaller than TD06,TD06 have bigger inlet/outlet plus bigger exhaust housing

Here is few difference:

On this picture smaller turbo is TD05,bigger is TD06



On this picture is difference in the turbine wheel,smaller is TD05 and bigger is TD06
