Subaru Td04L vs Saab TD04HL-15T
Turbo Mini Forums

I have been looking for a while for a saab Td04 and have not found one for sensible money either on ebay or at any breakers.

I just wondered whether anyone had looked into the possiblility of using the Subaru Td04L turbo as they are cheap as chips, obviously flanges are not the same, but as I will be making a manifold from scratch for the k1100 turbo engine flanges are not an issue.

Probably be looking to run about 15psi maybe a bit more and up to 8000rpm. Following a conversation with another member it seems the gt17 is puffed out after about 6k at 15psi with a k1100 head hence the original search for a saab unit.

I'm still researching this and just wondered whether anyone else had also looked into it?

Thanks

James

Well after a little research there appears to be quite a few variations of the Td04 fitted to various subarus - I'll keep searching.

IMO you want to be looking for a td04 or a td04L, the tdo4H and HL have a larger turbine which i doubt will boost till quite late.

iirc the std WRX td04l looks a good bet.

Pretty sure all TD04's fitted to Subarus here are the same. And they used the things from 1995 or so right through til about 2006 !
Only fitment difference is some may have had the 90deg front cover ( very old cars )

The compressor wheel is

40.6mm inducer
21mm tall
and I stupidly never measured the exducer diameter

Turbine wheel is 41mm diameter and about 16mm tall

They can be bought cheap as chips too.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

has anyone tried one of theses?

16V project underway

Why not a ball bearing turbo off of an iveco van? Good on small cc engines (eg 1275+)and good for over 200bhp. Just have no idea on maps or style, but it's on the modern iiveco's and some merc sprinters.

Searching is all you need on TurboMinis

good on small bores? really?

I bought one then sold it again, deciding the GT20 was a much better selection!

Hi guys, been reading the thread,I'm running a 1275 16v k headed with a r5 t2 megasquirted, works very well, was at Combe this year kept a redtop on throttle bodies and a Elise powered car at bay. Don't think I saw any of you guys. Any way I've pushed the max out of the T2 about 16/17 psi, it's just creating a lot of heat and runs out of steam by 5.500. I'm sure the engine will take more boost so need another turbo. I've got the chance to get a saab td04HL15-5 turbo, has anyone ever tryed one with a similar set up to mine? What results do you think I should expect.

i would opt for the gt series 1752 or 2056 for large power outputs, the first one would be my option

The only reason I thought it would be ok is that a lot of the Toyota Starlet lads use td04's as an upgrade, those are 1300 twin cams, I know it's a modern engine probably very strong and well balanced compared to the old A series, but there quoting outputs of 300 bananas using then.

I have a TD04-11B (or could be 11G) which will be up and running in a month or 2. If you search just for TD04 you'll see lots of variants, 11,13,14,16,19... quite a broad range of specs and sizes despite the similar name.

I wanted a gt17 but the vehicle it was listed for had used both turbos at some point, and I ended up orderring the wrong one by mistake.

Specs for the TD04-11 looked somewhat similar to the GT17. Sorry I can't be more precise, it was two years ago that I did the research. If you want the compressor and turbine sizes let me know and I'll take it apart.

Hi guys, just a revisit to the td04 debate. I've done lots of googling and comp map reading the td04-13t seems to be a good choice for a k16v 1275. I've looked through all the td04 threads via 'search' which is interesting reading, although I can't find anywhere, here or Google, a list that 'decodes' the type numbers. ie what does the 'l' mean in Td04l what does the 't' mean in -13t. Any ideas?
