Hey Wally, have you selected a turbo for the 1200cc motor yet?

Yes indeed, had it for some time already now: its the stock turbo from a 2.0 wrx subaru: TD04L-13T. The 04L is a very small hot side, will be perfect for the little 1,2 I think. It spools the 2 ltr suby at 2,5K already I read, so 'normal' spool for the 1,2 should be possible. They are also very cheap to pick up from ebay: a 100 (whatever currency) will get you a good one most likely.
I am equally excited how this will turn out tbh

Just don't become sensible and permanantly trade small displacement and gas mileage over bigblock power

Remember you do have a reputation to hold!

Wow those rods are unreal!! i wonder how much longer they would have lasted. just goes to show much much strain they can go through before they do go bang!
definately looking forward to your progress with the 1200 motor....good luck

Nah, there's no reputation. Remember, this is all the internet; I may as well not exist and all you've seen are computer animations

On a serious note I am seriously looking to my still patiently waiting 74mm 'stroker' and how far out of the bores the pistons would really come with this one.
It would mean a displacement of 2466cc

LOL! Yeah,actually you're just a myth!

I would go with the 74mm crank too.You may have to use cylinder spacers,but that's no problem.You can make them any thickness you need.

Thanks Jeroen!

The new cooling system looks nice. Will a lot of rework of your intake system be needed with it compared to the horizontal setup?

Wally · #**1107** March 5th 2012, 18:26

Not much really I suspect, allthough usually you don't anticipate everything in a build as we all know too well. It will be nice to get a push-pull linkage again though ;-)

I bought a type 4 engine and your car is one of the stars in my “map” to follow! Hope you don’t mind..?
What are you going to do with intercooler? That tail was your “logo” in my eyes

Looking forward for updates!

No worries Scardeep: Intercooler stays there!
Not much updates yet, will be several weeks before parts are machined.

1200 turbo engine is now up and running again and with a FK7 and 1,4 ratio rockers.
Its "a bit" on the wild side for a 1200cc engine, but rocks from 3K rpm onwards.

First time on the wastegate (leaking BOV though) and up to 6200 rpm
