Small port 16v with F/A internals

[harkes]

Hi

This build all started back early last year when I saw Dan (oldeskewltoy) having some used Formula Atlantic pistons and conrods for sale. Living in China though it would be a VERY long project only being able to work 5weeks/year during my vacations in Denmark.
So when Hans Kristian (AE86 buddy) offered to do the headwork for me (as part of a learning experience with his new flowbench) + the rest of the engine I was thrilled - the build could begin!

I already had a lightly tuned smallport in my Coupe that I was thinking of selling off so the hunt started for a donor smallport. Those ones are NOT easy to find, but the [u:42f3aae616]third[/u:42f3aae616] one we bought was useable.

The rest is mainly Hans Kristian putting his skills and hours into the project and me paying the bills + helping finding the parts as much as I could being ~9000km away.

Engine ended up like this:
Fully balanced and build to 9500rpm
16v Small Port
Silvertop ITB's
Headwork by Hans Kristian
~280 Catcams with 9mm lift (we never found the precise specs)
F/A pistons and conrods
CR 11,5:1
Fidanza 4kg
OMEX 500 ECU

Sadly I did not have time to break in the engine while I was back in DK, get it on the dyno and get some numbers. So that will have to wait until spring next year - something to look forward to

A few more pics...

Oh and Jan and Martin had been working on a Lexus 6spd conversion so that went in too - sweet!

A huge thanks to all of you guys! See you for some road-testing in 2013!!!

Great job!
If possible, attach some videos with sound, can't wait to hear it!

I would suggest to move those injectors away from head toward intake and use thinner gasket if possible, 11:5 is pretty low for this spec/parts.

I was wondering what ever happened to your rods and pistons??? Glad to see you are using them.




11.5 to 1 with 280 cams is a touch low.... if you find you could use a bit more, you can likely take a 1/2mm(.020") cut from the head......

Cat doesn't seem to show a 280/9mm, do yours have any identifying marks??


If you click on the part numbers, the timing specs pop up... you might try using the timing specs to see if you really have 280/9mm cams.

Finally, if you are sure they are 280 and 9mm, you could send cat cams a request, show them the identifying marks and let them get you further info(timing info)

Good luck with it... and I would very much like to see a dyno print out when you are finished

this seam to be a cool sceamer...
