Really would like one of these

[dieselboy]

My nan had one before I knew anything about them. Think theyre stunning little hatches. Cost wayy too much now though.

Most of them are drift cars fitted with Lexus V8s now.


See Youtube.

Sounds horrible though.
They use (Suzuki usually) motorcycle throttle bodies linked together for that set-up.

I disagree! This sounds nicer still http://www.youtube.com/watch?v=Snm_5...eature=related
Although apears to take ages to increase in RPM - needs a lighter flywheel

I don't see what the deal is with fitting motorbike carbs or throttle boddies to car engines. Are they rated for a higher flow of fuel or something?

Space.

[dieselboy]

Space.

And you're wasting it

I knew someone who used to rally one, a UK RWD Corolla though. Most in the UK now are the jap import version, whatever they're called - Kumquat or something.

[KERRSURF]

Ae86?

[BUSHWHACKER]

Ae86?

Correct. Or Toyota Levin (Corolla) as they say over the pond.

Not necessarily, exhaust manifold runner length and diameter of the exhaust affect throttle response too. Remember BDA and LCB manifolds of the seventies/eighties? (Thats old skool tuning, you're much too young)


Car exhaust is a science, especially with V engines.

You're not wrong! But a lot of different things can effect the outcomes, like cam timing, valve lift and duration and port sizes....

I did play around with the cam timing though. I advanced it to give more bottom end power, as being FWD, the twin 40 trumpets only sat an inch or so away from the bulk head - so you could say I had a problem with induction. I then retarded the timing a little off what it was set to to see how it drove.
Bad thing was, it was engine out, head off job to adjust it.

beautifull car, would love to own one, but a bit pricey.

Could you not have fitted a vernier cam pulley?
Bit risky adjusting cams by 'feel' valves banging on pistons is not good.

Ported and polished a few heads back in the early eighties on friend's Minis. I can still remember the blisters from all that valve grinding.

[dieselboy]

I did have a vernier. Problem was, it was an OHV engine, and the cam cover wasnt easily accessible!
I actually converted the standard single chain to a double chain setup used on the Escorts. What a pain that was since no one designed it for the FWD crossflow type at the time. I never had any slap. Kent cams said that no less than 100 thou should be machined from the piston crown valve pockety type things. I had only 60 thou machined and never had any slap. Even up to over 7k rpm. I did have guidance from a senior engine builder though.
When compared to the Burton Power engines with the same spec, the engines he had built were making up to 30hp more (mine included).
I only adjusted the cam timing by a few degrees each way. May be four degrees.
