Found this rather handy web page various engine weights when trying to find out how much the Pinto in the Viva weighs (190 KG) and daydreaming about possible engine swaps. So is 70KG a lot to add on top of the weight of the engine that is already in the Viva, would it ruin the handling? No prizes for guessing which engine on that list I am thinking of  |

Its about the weight of a Zetec SE stripped of ancillaries on top of what you already have  Id be trying to go lighter than a Pinto, not heavier  |

I know what you mean about trying to save weight but I was thinking more from a "there is no replacement for displacement" point of view, rather than a Chapmanesque "just add lightness" viewpoint.

Whilst on the subject... does anyone know the weight difference betwixt the BMW M42 engine and whatever the nutter bastid 6-banger lump is in the E36 M3 Evo (3.2)  |

Thats answered a couple of Q's I had, Marina B series 345lbs vs TR7 290lbs....I think I'm heading in the right direction here!
Mind you, the caddy V16 is a bit of a boat anchor (1,300lbs)

not a clue on the engine weight difference nick but the 3.2 evo lump is s50b32 if you are thinking of an engine transplant go for the 3.0 more reliable than the 3.2;)

idea stolen from rattely eddie.

Reliability shouldn't be as much of an issue on a 3000 miles a year car that isn't used on track or drift tho'..... no?
It's just an option I am considering for extra 'poke' as one has come up cheap locally with all the bits on it. But if it's gonna upset the applecart, then I'll go back to thinking about 'other stuff'....

I have seen that chart before but not sure how accurate it was. The pinto on there is 190kg. I think it was said on here before that the pinto is about 135kg.
But then yo unever know if they are classing the weight with all ancillaries, exhausts, inlets or even gearboxes.
The pinto is about 40kg heavier than a viva/chevette lump. To add 160 kg to the standard weight in the front would be way to much in my opinion. Unless you are planning on fitting the engine so far back its almost mid mounted

Whilst on the subject... does anyone know the weight difference betwixt the BMW M42 engine and whatever the nutter bastid 6-banger lump is in the E36 M3 Evo (3.2) m3 engine is about the same weight as an m30 big six. 6 pot e30s are nowhere near as nice and pointy as a 4 pot, the weights just too far forward, especially with an s50 motor. IMO. |

If you are putting a much heavier engine in then you want to make sure its going to be worth it in terms of extra POWER. Some of the big heavy engines won;t make a lot more poke than the light weight small ones. Some of the big ones will make enough power (well torque) to rip the back axle out of its mountings... What engine you thinking of putting in there?
I agree that in some respects the Pinto is a heavy lump for the Viva!
Depends what you want the car to be really.
Also IMO if you are going to start hacking about to fit a bigger engine, get another stock Viva hack that and then if you don't like the end result you still have the Pinto powered one, as well as having it to run about in while you do the other conversion (which wil take much longer than you anticipate, unless your name is Slater or Adaptoman...)
EDIT: 70KG is a lot of weight, I'd think twice about adding that much to the front of the Oldmobile let alone a Viva...

I was thinking probably rather stupidly of a Small Block Chevy, cheap, easy to tune to silly power levels, and would return it to being a GM powerplant as well ;D It's early days yet and it goes well enough with the Pinto in it, my first though was a Cosworth YB turbo as that would just bolt onto the Pinto mounts for an easy 220+ BHP, but they are getting harder to find and a bit pricy  It's the Midlands Retro Rides Meet tonight so I'm sure I can get a few suggestions out of those guys "force some air into a smaller engine, they love it" I was thinking, bike carbs (as mentioned recently these can take boost right?) and then one of those Mini Cooper chargers of E-bay, I know some one in fabrication who could make some mounts up for the charger. Priority at the the moment is getting the interior sorted and doing all the little jobs you always have to do when you get a new motor and then the quest for more power can start proper ;D |

SBC is a cracking idea. But its lots of work. Ideally you shoudl reinforce the shell, seam weld all the engine bay and the front and rear legs. You will need significant upgrades to the front suspension or it will eat wheel bearings and eventually may well chew out the spindle on the stub axle. I was chatting to a guy with a SBC'd Vauxhall who'd had exactly that happen to him. The rear axle will need an upgrade, I'd go for a Scimitar SE5 axle, tough enough and about the right width. A Volvo 240 axle is a popular one for budget V8 conversions although not sure on the width for the HC.
You willalso need to cut out the trans tunnel and fabricate a new on into the bulkhead area. Even in the FD theres only just enough room for a Chevy box, and not enough room for air movement round it. I know Andy told me just to beat mine out for clearance but we ended up doing a new tunnel on the V8 FD. The HC tunnel is smaller.
As you're cutting the bulkhead you may as well cut it properly and set the motor back a couple of inches to improve weight distribution.
There are SBC Vivas about and they are riotous fast.
I know what you're saying about keeping it all GM, but the SBC has the disty on th back on the engine and this leads to fitting (or rather not-fitting) issues in smaller engine bays. I'd either look to fit one of the motors which has the disty on the front, or maybe convert to crank trigger ignition (expensive). Front disty V8s are - Rover, Buick small & big block, Mopar big block, AMC, small block Ford. The Gen II Chevy SBC comes with factory crank trigger ignition... Not the tuners favourite engine though. Easy to get 450 BHP from it if thats enough though. But not as cheap as 450 BHP from a trad SBC.
The Rover V8 is a GM design so thats sort of in the family. Also its only about the same weight as the Pinto.
How much power do you need? what is the intended application of the car?
