8ball Posted August 24, 2017 Share Posted August 24, 2017 Was just out the front and a suzuki carry all?? Tray back thing cruises past. (Pretty sure they were 2 stroke originally? ?) Some silly fucker has dropped what sounds like a Harley engine in it. Lol Actually didn't seem to go too bad either. 1 Quote Link to comment Share on other sites More sharing options...

Tiny and light. Picked this one up and lifted it on to the bench easily. Maybe modify the shit out of the soon to be spare engine!? Three bearing crank for minimum resistance and max economy... Edit: then add turbo. 1 Quote Link to comment Share on other sites More sharing options...
8ball Posted August 24, 2017 Share Posted August 24, 2017 I don't know how heavy they are or how big? But the GM ecotec 4cyl engine may be something to look at. Pretty sure the late model Camaro has a 2L turbo alloy 4cyl. 205kw or something like that. Should punt the HB along pretty well. Lol Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted August 24, 2017 Share Posted August 24, 2017 Even the higher spec 90 engine is pretty low compression. Chuck a low pressure turbo on it with suck through carb. Something like a CT9 or CT12 off a small Toyota would do it. Unbolt for wof. 1 Quote Link to comment Share on other sites More sharing options...
77magnum13hundy Posted August 28, 2017 Share Posted August 28, 2017 I have a couple of clutchplates here and are surplus to requirements, any good to you Alex? Cover the freight and they are yours 1 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted August 28, 2017 Share Posted August 28, 2017 oh awesome- thanks for the offer. I'll see what this one is like and I might have a spare too. If not I'll PM you! Now get back to work on that Viva! Quote Link to comment Share on other sites More sharing options...
azzurro Posted September 5, 2017 Share Posted September 5, 2017 my 2300 has the ol' o'ring as valve stem seal dealio. Cant see them doing anything much tbh, but cant hurt either. The 'solution' is to swap valves and guides for later 1500 (same engine, 2 less cylinders used up till the 1980s in poland) ones that have a modern style valve stem seal (which is basically a stationary o-ring...). I assume there is a similar workaround for the Viva. Its a fair faff and cost for the sake of a wee bit of blue smoke on overrun and some mucky vales, but while you're in there...

yoeddynz Posted September 5, 2017 Share Posted September 5, 2017 I think there is a difference between this head and later heads around the spring seats and there just isnt the room to fit stem seals. I'm not that worried either but yeah, like you said, while its apart I might as well slide some o-rings on. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted September 5, 2017 Share Posted September 5, 2017 My two cents, Those O rings really only work so long as the guidethis.e nice and snug. Once your guide develops "bonus tolerance" it works less well. Maybe you could use some umbrella type seals from something else? And regarding lapping in the valves, I would advise against doing this. Ive seen two engines where a nice tight valve seal led to lots of blue smoke. The poor old rings couldn't cope with the extra vacuum. 2 Quote Link to comment Share on other sites More sharing options...
rusty360 Posted September 5, 2017 Share Posted September 5, 2017 Got a gas set? Heat those studs up to red hot and were they are bolted into manifold and unscrew with vice grips. Try it you will like it. 2 Quote Link to comment Share on other sites More sharing options...

I'm guessing they were not made to fine engineering standards of Britain though? But I'm interested in your experiences. I reckon if an engine starts to smoke because the valves have been made to seal again then it was probably due for a rebuild anyway? We can always have a quick check with some blue to see what they are like before we grind but with all the crap sitting there I cant leave it alone. I certainly don't want to risk a valve burning out due to some carbon getting smacked into the seat. I'll look through my little stash of valve stem seals Ive collected and see if there is something that might work. Considering my current fitted engine is a the same setup without seals and its doesnt blow excessive smoke on start up or overrun I'm not that worried anyway.

ajg193 Posted September 18, 2017 Share Posted September 18, 2017 You know it's a proper oldschool Barry engine when the valves have been given the Makita one way Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted September 18, 2017 Share Posted September 18, 2017 The heads are interchangeable I think but not sure about combustion chamber shape and overlap - e.g. smaller bore may have a problem on the 1256cc head. There used to be a thing where you could do something like mismatch 1256cc and 1159cc parts and make high compression or low compression depending on turbo or non turbo. I figured it all out a decade or more ago and have now forgotten all of it, including what benefits it offers. Pleasingly, I have lost some knowledge of Vauxhall OHV engines. Shit yarn! 3 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted September 18, 2017 Share Posted September 18, 2017 Yeah- Ive filtered through some of the Barry stuff out there on the webs and something about comp ratios being changed via head gasket thickness too. I'll keep a look out for a head otherwise I can just find a decent usable 1256 and have all the power! Oh man... the big block. Plus all the added benefits of the later stronger rockers, head studs etc. The ports are actually not too bad in shape, well at least it appears that way to my uninformed eyes. Or am I being dreamy ? Three bearing crank for max efficiency..... Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted September 18, 2017 Share Posted September 18, 2017 You are mistaken about the ports. It runs vertical Siamese intake ports and the exhaust has a shared port for no. 2 and 3. All of the yuck. Shape isn't great and usually full of casting slag. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted September 18, 2017 Share Posted September 18, 2017 That's space efficiency right there. Only one of 2 or 3 is going down and drawing in air at any one time. Same goes for exhaust. Why make extra ports? Oh and petrol is heavy so having downwards facing ports is good because gravity. You silly man. Just wait... all the other manufacturers will eventually catch up. 3 Quote Link to comment Share on other sites More sharing options...
