Hi, long time no write.

I have a uno turbo 1300 (mk1) that I was going to put in my x but I have to ask the question: would the 1500 block be reliable enough (as a daily driver) to use with the uno head and turbo? or would it be better to stick with the uno 1300 block?

I think I'm going to put the 2.0 thema motor in my track car and the uno turbo in my 1500, I was just going to use the uno in the track car and keep the 1500 stock in my daily driver. But it might actually pay off to sell the 1500 motor complete maybe...

yes it can physically be done, Ash Simmonds in Adelaide is running a Garret GT something on his 1500. You just have to take the right precautions with lowering compression ratio, normal turbo stuff. However Im not sure about bolting the UT head onto the 1500 block, I think there may be some issues but I dont know enough about it to comment

The Uno Turbo head is pretty much identical to the 1500 FI head - enough so that the two are interchangeable.

The earlier 10 stud head is not interchangeable so if you have an early 1500 engine then you are out of luck when it comes to just swapping heads.

The Uno Turbo block is the same as the 1500 block (with the same caveat as above), the differences are the oil jets and obviously the pistons, rods, etc.  The UT pistons are pretty good thanks to being redesigned by IHI and obviously more suited to a turbo application than the 1500 pistons. You could happily use the 1500 block in place of the UT block but I would recommend trying to stick with the bottom end or going for custom forged items to the same end.

It was put away for the summer and will be re-emerging very soon - I am going for a lap of Tassie in late May so it will either be fully sorted by then, or I'll be looking to sell it to make room for something a little more modern...

I'll update here once I get partway sorted on it.

I think he just used the manifolds and such from the Uno Turbo. I remember that he posted up on X-Web about his experience. He had a few cautions, but overall, it was a great swap. You might find it on a search.

this is the route I'm taking (temporarily) as the 1.3 Mk I is still torn apart. It all fits, I've had everything on except for the alternate oil line and intake section.

I'll post up progess as soon as this goad forsaken weather warms up enough for me to work in the garage.

guessing this wont bolt up, maybe I will just stick with the uno 1300 and play with upping the boost, intercoolers and water/methanol injection.
