engine weights...1.9/2.1

[Piggy]

I have searched till my fingers have gone numb....

I cannot find a defo KG weight for the 1.9, lump bare.

And even less info on the possible weight of the 2.1 lump.

I have assumed it be heavier...but then some may assume the GTi engine is lighter, yet we all know it isnt.

I need to know weight differences to help in calculating the right LBs spring rate for the coilovers...

any help appreciated

The 2.1 is heavier by 10-20kg at a guess, maybe even more.

I know it sounds OCd...but I have OCD my wife and friends tell me...so really want to know!

I have a old set of scales...so could weigh the 2.1 but would like to know the weight of the 1.9??!

So...

a 406 hatchback 1.9 LX Td weighs 1335kg....

a 406 hatchback 2.1 LX Td wieghs 1415kg...

thats a mighty 80kg, yes EIGHTY kgs heavier......but to factor in that the gearbox and flywheel from a 2.1 is heavier too....

any thoughts on how much heavier the 2.1 gearbox/flywheel would be than a 1.9???

^^^ Could be thicker shafts, stronger springs and shocks, bigger brakes, bigger wheels, thicker ARBs and TBs etc all adding up to that weight.

hmmmm....that dont help a huge amount then...it was a good try in my eyes when I first thought of it

PS anyone know what the standard coilover spring Lbs is? (for a 1.9td?)

[2.1 dturbo]

I had 350's in but have 325's in now and prefer the 325's
But I'm on 406 box shafts as well

interesting....thats good info...

I dont want to go too hard...Im not building a track toy....

got some real soft 180s for when it snows...

but I was thinking 275 for rest of year by some quick calculus...

how hard is the 325 ride?? what setup have you got on the rear?!

[2.1 dturbo]

It's firm but not bouncy, the 350 were a bit bouncy.
Koni adjustables shocks all round, homemade coilys in the front.

Theres a whole thread on coilover spring rates here

http://306oc.co.uk/forum/thread-1270.htm...ring+rates

GAZ ones are 325 standard, cheap ebay ones are about 200 standard

thanks dum dum...I did search but nothing came up?!?!?

[strictly_perv]

Theres a thread over on 205gtidrivers with engine weights, think it's called difinative weights thread. Think the 1.9 is 140kgs.

EDIT Weights thread

1.9- 140kgs
2.1- 171kgs!!

ive got a large crate full of different coilover springs, no idea what the spring rates are though, but i imagene some of them are quite hefty as they all come from various rally cars, everything from gravel to tarmac setups. is there a way of identifying spring rates?

[Piggy]

thanks strictly....you're a star...repping you for that


the spring should have on it somewhere a number....but if its old and bashed about you may have no luck...

you can start by measuring its size...Inner D and length but the important Lb'age would need a special machine for checking

That would explain why I struggled to lift a 2.1.
