Is there any way to tell from the photos that this is the real thing? It could be an interesting find - http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=110619365180&fromMakeTrack=true&ssPageName=VIP:watchlink:top:de

TiSA Head Facts -

Larger intake and exhaust valves 44mm intake, 38mm exhaust

300 or 324 degree camshaft

Different combustion chamber

Pistons matching the new chambers in either 10.5:1 or 11.5:1 compression

By those combustion chambers that's a 121 cylinder head..... like this. Could be an 118 head as their combustion chambers are VERY similar.

Here is a real TISA 1 combustion chamber....

Then a Ti/SA head that's been opened up for Alpina "hemi" 12.5:1 pistons....

Now the Venolia copies of the Alpina pistons that go with those open chambers....

I thought 44MM was std intake valve size, no?

Before you think that 44mm was the standard size for M10 intake valves you must ask WHEN 44's were first used in M10's.... The Ti/SA head. The earlier 116 and 118 heads used in 1500s, 1800s, 1600/4s, 1600-2s, 1602s, and 1802s had 42mm intake and 35mm exh. valves. Remember that the 1800 TiSA was based on the 1800 Ti which had a standard 118 head. At the tme the performance and power of the TiSA's engine bested even Alpina's efforts. Racing versions had nearly 170hp. In the early 90's there was a FIA Historic championship and a firm of Scuderia Bavaria working with BMW developed the Ti/SA motors to over 190hp. Though, the powerband was from 5500 to 8000+....

I see... did I measure properly w/ my pic up there? Jim, the head you have may have had the valves replaced at some point?

Don't mean to alter this thread, I guess my questions are truely relative.

Scott - I believe all tii's with the 121 head came with 46 x 38 valves. I'm certainly no expert, but that info is in Mike MaCartney's restoration book.

Let's get this back on track. I for one would like to see more TiSA stuff!

Now, where is that post showing the German woman posing with the Ti (or was it a TiSA)?

I thought that list looked familiar. I guess the ebay seller pulled the info from the UK site.

There are some really cool NK photos in that forum. I love the thread on NK's with different alloy wheels.
