engine and drivetrain Building a TISA engine

[ErikBerg]

My brother is about to build a TISA replica engine. He´s already got TISA intake manifold, Weber 45 DCOE15/16 and brand new TISA-pistons.

Now we have established contact with a guy who possibly has got a TISA head and engine block!

Are there any more engine parts special for the TISA?

By the way, I found these beauties at an internet auction yesterday. Quite rare stuff these days!

sorry to hijack, but I what is the history of the TiSa engines and cars.. it'll make the build more interesting.

I have a buddy with a TISA close ratio 5speed gearbox that has just been rebuilt. He wants to sell it , interested ?

I' m sure this is one of these "if you have to ask" items... But I'm interested in details. Please email me via the button above.

Thanks!

If in your searches you happen to come across another set of pistons and head I would be seriously interested. OR if you are interested in letting JE or another piston supplier make a scan of the pistons......

Dad's TiSA... The pistons are Venolia copies of Alpina 12.5:1 hemi racing pistons and the chambers in the head have been opened to match.

WOw,

great job finding those parts! Ibet those were hard to find!

I attach an article written in 1965 ..test Drive of a BMW TISA for everyone's enjoyment.

Thanks,

As a matter of fact, last summer my brother and I were lucky to buy 3! sets of TISA pistons!

2 of these are sold, one to Sweden, one to Belgium.

My question remains; are there any more engine parts special for the TISA?

Engine block?

Exhaust manifold?

I am VERY interested - what's he want for the gearbox and difficult would it be to drop in a '67 2000?

[rey949]

I know the block is an early 1800 with an 84mm bore and stroke/ bore ratio at .95

Does the TISA engine block have the same number as the car?

Like at other old BMW´s.

Btw, i helped the swedish guy who bought my pistons to find the 5-speed TISA gearbox. Found one in Sweden, $440! Guess if he was happy!

He is building a 1800ti for FIA-homologated racing. Will be nice!

My supplier might one last set of TISA pistons...I will check.

[rey949]

Not sure about the factory race cars, but the homologation specials would have to have matching numbers.

[tjones02]

Yes the block would have a matching VIN to the car. The crankshaft is counterweighted like that of a 2002 crank... are you going to use a 6 bolt or later 8 bolt crank? The camshaft is either a 300 or 324. Witch cam do you have?

Emailed interested persons regarding TISA gearbox.

I believe my brother has got a 324, or it might be a Schrick 328/328.

I would caution anyone that has a TISA 5 speed. The transmission is very fragile in comparison to the newer transmissions. I have rebuilt one in the past and the gears look very narrow. I know that the 4 speeds are prone to break second gear very easily. G
