I don't know at the moment but I have both engines and gearboxes + diff that could be weighed given time. How big is the hurry?
Hi Andy. thanks for the quick reply. There's isn't really a hurry regards commencing work on the project, I'm just trying to look into possibilities at the moment. Any info. re. weight will be gratefully received.
I'd be interested in your proposals for more power and/or less weight. It has been done by many before you but using relatively old engines. A Hyabusa with a chain drive would be fun! I have recently seen several fitted in Westfields and Caterhams at sprints.
Yes, indeed. A bike engine would be fun.
There is a company called Z-Cars that does a bike-engine kit for the Mini as well BUT in the case of a Bagheera I think it's a little too anarchic a notion for me to contemplate so I'll stick to a more boring solution!
I believe a Suzuki Swift GTi engine (DOHC 1.3) mated to a Suzuki Samurai (small 4x4 jeep) gearbox is about 90kg (the engine alone is an ultra-light 54kg) but they have 100bhp as standard and may prove difficult to get much more than about 125bhp from easily.
Ideally I'd choose something French. The PSA 405 Mi16 (all-alloy 1905cc 16v, 160bhp) engine is a possibility (most seem to have made their way into 205 GTi's eventually) but I see that they have some oil-surge issues and I like the idea of something smaller.
Another possibily is the PSA TU3 (1360cc, found with carb in the 205XS, Citroen AX GT and injected in the AX GTi and 106 XSi) The TU engine series actually replaced the Simca Type 315, which included the 1294cc and the 1442cc which are found in the Bagheera series 1 & 2 respectively. An English guy who's name escapes me at the moment runs a Peugeot 106 hillclimb car with a 1360cc TU3 mated to a 16v head (106GTi if I remember correctly) and his car produces about 190bhp!
My current favourite: The Yamaha designed Ford Sigma (aka Zetec SE), first introduced about 1995 and fitted in the Fiesta, Puma, Focus in 1.25, 1.4, 1.6 and 1.7 variants. The 1.7 from the Puma has variable valve timing so apparently from a tuning perspective the 1.6 is the popular choice. It's all-alloy and weight is around 80kg with ancillaries which isn't too bad at all!
The 1.6 produces 99bhp at 6000rpm but it's possible to get up to 220bhp (at a cost) using standard valves.
It may not be French but it's a worldwide engine, close in capacity to the Bagheera's original 1300/1500 and with Matra having a history of using Ford engines, this makes it seem 'right' too.
Here are the dimensions of the Ford Sigma engine:
