Tri Carb Turbo Austin
Turbo Mini Forums

Thought this might get some looks....

Looking to turbo my Austin America (1300) and did some mock up with an intake setup to check for clearance. Looks like I should have plenty of space for the carb/plenum setup and enough on the back side for the turbo, although I may consider the mirage manifold and t-2 for quicker spooling. Not looking for a high strung engine as it is now...more for a bit of low end pull up to 80 mph or so. I may also consider fabricating a side mount manifold since I have tons of space over the flywheel housing for turbo and intercooler bits....I'll be asking lots more questions soon!







Lots of legroom here for turbo goodies and piping!

Nice. But whay not use the 7-port head for the turbo?

Stunning car!!

Hey wil_h, keeping options open for the 7 port turbo....figured that I wanted to get the turbo setup properly on the 5 port and work my way up to fuel injection, etc....but I need to figure my basics first...

+1 for 7 port turbo.

In the 13's at last!.. Just

Plenum on the webbers, big intercooler underneath (in that big grille) and a GT17 down the back. perfect.

injectors....

oh i do like this car, + for the 7 port.

7 port injection for me too!

If something is worth doing, it's worth doing half of.

Thanks for all of the +++ thoughts! I appreciate all of the regulars on here speaking up with support!

I did have a thought of doing the turbo on the back side but up high via upside down style mirage with a plenum style setup (similar to Joe C's). Would be a lot easier space wise for me. I had a similar setup on my old GTI, but that is a long story with a shady shop....that is why I want to do this one myself. I did check and I do have the space to reverse even the stock metty manifold on the back side of my engine bay.

You know what to do!

the car must go great as it is?

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Crap, now I might not be the first to turbo an ADO16

yes gr4h4m...it does go very well, although I'm having issues getting the bottom end tuning just right with the webers. It is very on and off at slight throttle....after 3k and 1/4 + throttle it runs like a dream with lots of power all the way up. To make me happy, I would need to go fuel injected to make it run the way I want it to. If I am going to go through that much trouble, I might as well put the turbo in the mix to get some extra bang for my work.

Vegard, you had your chance...
Or at least maybe this will get you back on task with the ADO....

Fortunately, I have a complete spare subframe and engine assembly to do all of the mock up in the garage without having to take the America off the road. I also have a very anxious 14 year old son that would love to help me work on it!

Whatever you choose that is still going to be a stunning car!

Hey robert, not too much cam...went with a kent 276 on this one. At this point, I am a bit rich on the idle jets as there is a tiny lean spot barely off idle or slight throttle cruise. Unfortunately, I go to the rich side to finish the progression until it opens up a bit to the mains.

I previously ran a weber 45 on a maniflow intake on a Calver GT head with a 286 scatter cam that was tuned spot on...

I just can't leave well enough alone!

great motor

Thanks robert for the advice....I am currently running the med 1.5 rockers in the head that they did the flow work on as well with a larger intake valve. I haven't tried the standard rockers or loosening the tappets (currently at .016). I did try using 30mm chokes, but they only lost out on top end and didn't help bottom issues over the 32's. I'll keep fooling with the idles. I do have lots of spark with the pertronix coil and the 123 distributor & 8.5mm wires. I'd like to get this sorted before I move on to additional projects.

One thing...I have been unsure of my cam timing since I did the head as I also installed a belt system. To the best of my measuring, it seems slightly early on the timing (should be 106 at full lift, but seems to be about 103-104). I can't for the life of me figure out how to get it adjusted as moving the dowel doesn't seem to do squat as per the directions that I have read 50 times over.

Well robert....I got home and re-set my tappets to .018...made a major difference on the low end...just need to fine tune that last 5% now with the idle jets....

Thanks for the advice! Made an excellent B-day present for me!

Just did some idle jet adjustments....now I'm within 2% or so of being spot on! Just need to fine tune accelerator pump jets...
