GTV-S2000 (warning not for the Alfa purist)

Thanks Kev...Would be a bummer after all your work.

Kevin,

Fascinating project, how does the s2000 lump compare for weight?

Have you planned how you are going to sort out the engine cross member yet whilst maintaining adequate ground clearance?

The motor i'm very keen on going a conversion to is a Rover K-series - they weight a mere 79kgs and the VHPD items they are putting in the best Caterhams are 250bhp... if mated to a Caterham 6 speed sequential box I think it would make a hilarious drive!

Max,

Good question, I have been trying to figure out an economical
way of weighin both engines. Thought of using a strain strip
on the arm of the engine hoist, and lifting each of them the
same way and compare readings. I think the strips glue onto
beams, and one can measure the change in resistance as they
are strained. Not sure where to buy these. Anyone have ideas?
I guess bath scales are out

As far as the clearance, I think if you look a few pages back I posted
a pic with the motor in place. I think that the oil pan is actaully less
vulnerable than the Alfa's, in fact, I dont think I need any guard.

Max, I have been surfing your website, and love your suspension kits.
Especially the lightened spring pans, and small springs!
When I start building the suspension, I will definetely contact you.

The project is moving at a turtles pace, mostly due to work. I have
been cutting small bits and peices to finish the welding of all the cross
members, and new floor pans, and tranny tunnel. I should get some time
this weekend. I'll post more progress then.

christ... I can't keep up with this thread... go to bed for one night and my post is buried under 3 more pages of chat! Very popular Kevin! Best of luck, drop me an e-mail at my company address at any point you like...!

[Max Banks]

p.s. I would just weight the negines on a pair of bathroom scales once you have made up a pair of cradles for putting the engine on... unless you have flat patch corner weight scales.

come to think of it, 2000cc Alfa engines weigh about 100 kgs give or take 5kgs, so a bit of Google action will probably come up with the weight of an S-2000 engine without need for manual labour... unless fingering a mouse is classed as manual labour.... ohh did that come out wrong?

Its 386LBS.. thats without the tranny

heavier than the alfa engine .. but twice the power...

[Mikes4C1300]

A couple of threads on s2ki.com put the F20C engine (sans transmission) at 326 pounds. 2.2L shouldn't be significantly different. Couldn't find anything on trans weight.

can't be 386 lbs surely... thats over 170 kgs... does it have an iron block or something? If so i'm gonna have to put a serious thinking cap on for spring rates for you Keven!

326lbs is what i got for 2000.

[Keven]

I bought a scale on E-bay (I love E-bay ), not a comercial grade
one mind you, since those costs hundreds of dollars to weight something
around 400lbs. And for my puposes, I really want to see the difference
in weight between the S2000 and Alfa (motor & tranny).

Drumroll please.... And the weights are:

Alfa 1750 fully dressed minus header & air filter canister : 380 lbs

S2000 same as above but also with ac condensor : 380 + 43 = 423 lbs

So only a difference of about 43 lbs. Max, any need to change spring rates?

I had to use a bath scale under the tranny, because the hanging scale
only goes to 400lbs. Now its been a long long time since I took statics,
and I did not exactly ace that class. But if memory serves me right, my
set up should be ok, since the forces are in the same axis (though opposite
in direction), so they should simply add. Feel free to correct me if I'm
wrong. And as always here are a few pics of the setup..

For you nitpickers, I subtracted 10lbs for the engine tilter (which I weighed
separately) I have on the S2000 motor, thus the bath scale shows about
53 lbs in the pic.

[Barryh]

Kev,can you shoot me a pic front on of the Hondola engine??
Thanks..

[slyalfa]

hmm how much is car battery? I think just moving the battery and you null the 43 lbs

I might be wrong but if you move 21.5 lbs to the back aka the battery
that will fix the 43lbs in the front.
and it will be less then that for real as the 43 lbs is spred out not all in the very front.

[Keven]

Barry, I'm posting a pic of the front of the S2000 motore.

Slyalfa,
I am planning on using a dry cell battery that is only 12 lbs.
Good point as to the weight distribution. Now you have me
thinking of how to find the CG (center of gravity) of both
motors to predict effects on the front suspension. I can
tell you that since I cut the crossmember, the S2000 motor
sits lower and further back that the Alfa motor.
Is it me or, am I over thinking this?
