can anyone out there tell me the weight of a 16v and 8v 1.7 engine?......or the single weight of a 8v and a 16v head would do.......I need to know this info before I commit to buying either engine.......as my engine is hanging out the rear on a beetle gearbox of a kit car, so if the 16v is say 20Kg heavier than the 8v, that makes it bad news for.......any info much appreciated

cheers

I saw such a conversion in a Hillman Imp. He had also chopped the roof off. Think the engine was an 8 valve. But as suggested make it mid mounted; that's how it is in my Clan Clover (and you get a five speed box).

From my experience of carrying a 16v engine complete with ancillaries I would say it is 'pretty heavy'.

This may not be useful information.

thats my concern that the 16v is much heavier.....possibly by 20Kg, but I'm guessing.......even the single weight of a 16v and 8v head would probably do, as I already know the weight of a 1.5 sud engine.......which will be very close to the 1.7 8v.......please someone help me!!!!!

I have both heads at home. I'll check for you and do check next week. Or someone else...

serpent - you are a god!......please make sure you include all the cam shafts on each 8v and 16v head that you weigh.......just so I dont get the maths wrong!.....please clearly state if an individual or x2 weight

cheers

My apologies my friend. Hope it isn't too late. I went to dig the heads as soon as I read this.

12.5kg for single 16v head with cams,valve assembly, no sprocket

3 kg for single 8v head with valve assembly without cams. I estimate another 2-3 kg for cam and housing so it's about 6kg.

all done on bathroom scale. My apologies again.

nice one serpant......so its about 12Kg totat difference between an 8v and a 16v.......sounds about right

I think it might be even less. My car shows no difference in height since engine transplant.

If you're talking about car's front height it' would be virtually not possible to see with a 12 kg difference. Imagine a 12 kg toddler sitting on the car. Furthermore the 12 kg is distributed equally to both sides.

my engine is in a beach buggy, rear mounted on a beetle gearbox. hence, more weight on the rear is less on the front!......but 12Kg should be OK.

Hi Knight my kitcar has a 16v engine its about 128 kg, my old kitcar had a 1,5 8v at is were 104 kg heavy..... You can easly make the weight function at your kitcar feks put the gastank in the front of the vw chassis...... anayway i know guys wich dries with porsche 6 cyl and rover v8 at a beetle so it can be done... but yo are right about the weight.... In my opinion you schould pic a motor under 135 kg maximum......

This may sound a bit left field but the drive shafts have universal joints, or CV joints in the case of a front wheel drive set up. It should be possible to offset the wheels towards the back in a rear engine configuration so the engine and gearbox weight is further forward. If the axles can articulate in a vertical plane there should be no reason why they should not articulate in a horizontal plane as well. You may have to limit the offset depending on the type of universal joint but front wheel drive CV joints allow a lot of displacement from straight - think about steering angles.

I don't know if this will create any torque reactions but if your suspension pick-ups are reasonably solid I would not expect any serious problem.

All the best
