I reckon the C20LET might well be heavier than the V6 (ref minifreek's post), especially with the turbo strapped to it - IIRC the LET is a cast iron block and the V6 is all aluminium..

Certainly the internets reckon they're both about 130-150Kg..

The 1.8 MX5 engine, by contrast, weighs ~120Kg with the 1.6 at ~100Kg..

V6 is an iron block and alloy everything else. 

Block is not very big on the V6 either.

[aaronjb]

Ah .. always thought it was all aluminium rather than a boat anchor!

[Marks DTM Calib]

Interestingly, many of the aluminium blocks are not much lighter than the iron ones as you have to add a lot of extra material to get the strength (which does help sound deadening also)

[tigers_gonads]

Brodie Britain Racing bolted a turbo to the original 1.6 when it first came over here.
Went rather well iirc

Shame some retard has put tyres on it that are about half the section of the rims.

Still, I like the idea. 

I doubt it's added more than 50kg to the front end weight, so I reckon it'd handle OK.

The tyre stretch boys will like that  Will make an interesting ride for sure

small cars are choosen for a reason.. 30-50 kg is a considerable weight both for acceleration and cornering.. I wouldnt prefer a na V6..   and also even a high pressure turbo 1.8 engine would make that car uncontrollable

[aaronjb]

No way would it be uncontrollable with a turbo strapped to it, cem.. If 250hp+ in a mid engined MR2 Roadster with almost identical weight, with all the weight out back is controllable and fun (and I speak from experience here), a front engined rear drive MX5 would simply be a blast.. swing the back end around the engine and enjoy!

I agree that 50Kg is a lot in a 1000Kg car, but let's face it.. the difference between you driving it and me driving it would be more than 50Kg in a less favourable position in the car..

[Kevin Wood]

I agree. Try driving the standard 140BHP 1.8 car on 185/70/14s before deciding. Again, speaking from experience, you can give it everything that engine has and the chassis remains absolutely planted. Boringly so, in fact. I reckon an MX5 in the 200-250 BHP region would be an absolute hoot and nowhere near uncontrollable.

[aaronjb]

I'd certainly sign up for a go in one

Which reminds me.. one day I ought to ask you if I can try the MX5 on for size (if you turn up for a curry in it). Always wondered if I'd fit (I'm pretty sure I already know the answer when it comes to Westfields so no need to ask there! )

[Diamond Black Geezer]

The amount of times I've managed to get the Turbo Weasel tail to kick out (umm.. only about 40% of the time on purpose  ) with 140bhp (and no TC on the Diesels, of course), I really dare not drive that MX-5!!

question is: what do you understand from a high pressure turbo ?


1- 1.5 bar  is a usual pressure region not high.. but even if we assume you run that car (- 1.8 - )  at 1.5 bar it will be more than 300 bhp (remember thats a 1000 kg car) ..  I have driven  a turbod clit rs (2.0) at 1.3 bar and when you hammer it the car goes wherever it wants independant of steering


sorry cant agree

[cem_devecioglu]

how abouts 2.5 bar

[aaronjb]

I know someone who had 400rwhp (yes, hp at the wheels) in a Mk3 MR2 and kept that on the road quite happily (in Finland, although it wasn't his winter car - that was a Mk2 Supra turbo).. enough HP?

You can keep anything on the road and have fun in it if you're sensible and have a modicum of mechanical sympathy; yes, over a certain point all you've got is hp to light the tyres up, but 300hp in 1000Kg? Sure, I'd consider that "fun" territory, not "death" territory.  Remember, I've driven 250hp/tonne cars.. heck, it was my daily driver for about six years - summer, winter, snow, ice..


But there's a big difference between a 2.5bar turbo engine and the V6 these guys have dropped in.. so now I'm confused why that was even brought up?

now lets forget about 2.5 bar..    300 bhp in a 1000 kg car is more than controllable imo.. esp if its a fwd.. a rwd , may be  .. assuming manual transmissions..


I'm running at 0.8 bar currently and even in wet if I hammer the car starts to jump.. honestly
