CF-L Head?

Posted December 9, 201311 yr

I can't decipher this one? B110TS???,KP61,240ZG,BMW?????(?)?240ZG?CF-L???????

Did he make a new head or is it some Toyota engine... sort of looks like an S30 block underneath but a different timing cover

That appears to be the LY crossflow head made by Nissan to homologate for FIA Group 4. Pretty rare and very expensive.

Thanks! The coolant ports around the domes look a bit "toyota"

I found this pic which looks more "nissan"

It's not an LY.

'CF-L' is an acronym for 'Cross Flow-L (series)'. It's basically a single-cam RB head converted to run on an L-gata 'block, with dedicated castings and specially machined components.

Guy who made it ( them ) in Japan has a blog showing the whole process.

( Edit: Sato san's blog is where you found it..... ).

Found this pile of pics: https://www.google.ca/search?q=cf-l+site:sato1511.blog40.fc2.com&num=100&newwindow=1&espv=210&es_sm=122&source=lnms&tbm=isch&sa=X&ei=Vg-mUsL-Fq6gsQSd_IG4Bw&ved=0CAkQ_AUoAQ&biw=1137&bih=527&dpr=0.9

Still trying to figure out how he did it and the details of the required machining and custom parts.

Google translator is a little rough but better than nothing. If I understand correctly he warns people buying new Weber carbs made in Spain to clean and check them carefully before running the engine, he found powdered metal from fabrication (and a missing o-ring?) in them.
