After mercilessly hijacking Joeh's weight saving thread I thought I'd do the decent thing and start my own.

After what I thought was a silly suggestion of dropping an LS1 engine into an S2000, I wondered how realistic an idea it could be.

When an S2000 engine goes pop, it's typically £2500 + fitting costs to replace it.

However, an LS1 engine typically goes for £1100. I plan on doing a bit of research now into finding out the theoretical costs of fitting one into an S2000.

Now while this is all speculation at the moment, it seems that a semi-reasonable mpg figure could be maintained and insurance hike is staggeringly low according to a quote I just got from Adrian Flux (£288/pa uplift).

So I'm guessing I'd need to figure out;

1: Fitting the motor and gearbox (unless the S2000 gearbox could be retained somehow)
2: Custom exhausts
3: Intake system
4: ECU
5: Brake upgrade (If necessary)
6: Suspension work to take into account the presumably heavier engine.

What else is there to consider?

(I'm at work so not had chance to do a proper forum search to see if it's been covered before)

things to consider:

1) go to v8s2000.com
2) read it.

That is all.

You will loose the 3 best things about the S, 9krpm limit, best manual gear shift of any car, and weight balance (though the V8 might not actually be a huge amount heavier?).

Good luck though, difference is good and it'll be interesting to follow your developments.

Joeh

Some LS engines have higher or simular rev limits

Aluminium cast V8 engines (although they are expensive) don't carry much more weight than the S2000 F20C2 (obviously heavier though)..

How about loosing 1 of the worst thing about a F20? No torque d:

I'm never sure on engine conversions. To me the engine is literally the heart of the car, and i'd probably look at just buying another car instead.

Don't you keep the gearbox and get an adapter plate to connect one to the other?

Failing that .... get a full auto

Lol I think they gave up, should have been finished in q1 of 2010 d:

I agree completely with MB about what he said.. but a contrasting view would be that sometimes you don't have the perfect match by default from manufacturers.

But on the point of MB, the S2000 has a more refined "hardcore" NA race chassis / setup, which is just a step before turning into an caterham/ariel atom, you can't really get closer than that for a proper car, and its true.. it can be easily ruined with the wrong engine for example.

YOu would make a lot of engines rev to over 9k if you throw enough time and money at them, but thats not the point of this project? I thought it was due to the cost of a replacement F20C being quite pricey?

I did mention the V8 might not be that much heavier, though any increase will still negate the huge amount of R&D spent by Honda + other tuners on geometry and suspension settings, thus making things pricey again when having to discover this new territory.

and your last point, I disagree the F20C has "no torque" it has plenty where you need it

Joeh

Lol sorry my previous reply was quite childish, the f20C has a fair bit of torque and can be increased depending on the gearbox setup

I actually like the F20C in an S2000 more than any other engine, because that's what gives it the edge in small and technical courses, ESP against cars in the same class


But the thing is that most people here are not racing them, just driving them so... They would like more power for the road.. when the want it and not wait for it..

So LSx in a race S2000 = no.. Unless they need a reliable drift car then that's different d:
