ok i have a turbo 2 '87 question is its really a dumb question but can someone tell me the turbo sizes like for example what is bigger what is smaller , like t04, t70? etc...... the bigger the number the bigger the turbo or No? thats something thats always got me confused ....... By the way i posted a while ago about porting tools , i ended up buying a micro grinder its a bit fatter than a highlighter marker (to compare in size) an its rpm's are beautiful works real good , small compact can be held in one hand like a pen ......

im no turbo genius, but i think that theyr different by brand. right? and like the t-04 is smaller than the t-06 or 08 and the t70 is bigger than the t60 or am i mistaken?

DEZERTE

you have the hitatchi t18, and it depends on the brand i think, bigger number, bigger turbo

Garrett turbo FAMILY sizes
T25 < T28 < T3 < T04 (T04B < T04E < TA45)

Garrett GT-series FAMILY sizes
GT25 < GT28 < GT30 < GT35 < GT40 < GT42/45

Mitsubishi turbo FAMILY sizes
TD04 < TD05 < TD06 < T67 (hybrid TD07 and TD06) < TD07 < T78 (hybrid TD08 and TD07) < T88 (or TD08)

For 13B applications, we're really only concerned about Garrett T04 and Mitsubishi TD06 models and larger, for single turbo applications.

Garrett T04B (compressor) models
S-trim < V-trim < H-trim < 60-1 (Turbonetics calls it a T04B family, although others call it a T04E family)

Garrett T04E (compressor) models
"46" trim < "50" trim < "57" trim < "60" trim

Turbonetics (compressor) models
T58 (TS04) < T61 < T64 < T66 < T70 < T72 < T76

Now that you're thoroughly confused, other manufacturers use different nomenclature for their turbo models. There seems to be a current trend to use compressor wheel (major) diameter for turbo (compressor) models. Thus, a "PT67" is a 67mm compressor wheel, but it's supposed to be the same size as a Turbonetics T66 - go figure.

Then there's the HKS stuff, which they like to make their own models names - T04S (not to be confused with the TS04), T04R, T04Z, T51R (the T51R Kai series is based on a Garrertt GT42).

It's very hard to compare turbos across different manufacturers.
Just to give a loose idea of specific turbo capabilities...

Garrett T04B V-trim - 300hp
Garrett T04B H-trim - 350hp
Garrett T04B 60-1 - 400hp
Garrett T04E "60" trim - 400hp
Garrett GT3540 (GT35 turbine / GT40 compressor hybrid, BB center) - 400hp
Garrett GT40 - 500hp
Garrett GT42/45 - 600hp+
Mitsubishi TD06 - 400hp
Mitsubishi T78 - 500hp
Mitsubishi T88 - 600hp+
Turbonetics T58 / TS04 - 400hp
Turbonetics T66 - 500hp
Turbonetics T72 - 600hp
All numbers are at the wheels on a DynoJet and on pump gas (92 pctane).

I haven't even covered the A'PEXi (IHI), Blitz (KKK), and others...

would all of them fit into our cars which one is good to use on our cars and make 400rwhp on medium boost and 450+ rwhp on high boost

also reted if i need help with a t2 engine when i get a t2 would you be willing to answer my questions when i upgrade the turbo and what else i need to do when i upgrade the turbo

RETed

Define "medium" boost and "high" boost?
The above numbers are for each model at around the limit of pump gas - at around 17psi to 18psi of boost.

I can try and help if I'm not too busy.

whats the best kind of single turbo set up for a 13b-re?
Thanks

calio64

very good info ted, im saving this post

RETed

Depends how much money you got and what kinda power you're looking to make?

Expensive, best, fastest spooling up to 400hp - Garrett GT3540, 1.06 turbine A/R
Cheap, economical up to 400hp - T04E "60", 60-1, TS04
Economical up to 500hp - T66 or equivalent

I prefer the Garrett turbos due to the fact that they are easily and cheaply rebuildable in the U.S.

im looking to get 1 that would put me around 400rwhp, whickh 1 of those doesnt have too much lag?

RETed

GT3540 would have fastest spool-up, but it's also expensive!

Any of the 60-1, T04E "60", or TS04 will do the job.
Drop the turbine A/R down for best response.

gt3540 vs gt30 would be fast spool?

and make 400whp?
