Any of you running with these engines, looking to upgrade my S1 next month, but can't make my mind up

I know someone who is running a blink Honda conversion . . . the car is quick, but IMHO nothing like quick enough to justify the cost . . .

Out of interest, why are you changing engine ?

Holeshot are working on a Hayabusa turbo installation for Elise - you know it makes sense!

7.5K for 190bhp is still a lot of cache . . . warantee or not . . .

Surely the bl!nk conversion is as much about the sound, feel and characteristic of the engine as it is about the power of it??

Also - dont you think it would be rather nice to replace a K-series which is relatively delicate when highly strung with one of the most reliable production engines ever produced??

Makes alot of sense to me.

Lotus have just done that - it's called the 111R!! (how long before a Toyota vs. Honda war breaks out again ). 10k is a lot of money to spend on mods and they won't be worth anywhere near that when you come to sell it.

The Hayabusa sounds interesting and a bit - no doubt a load of money too but it would give a serious weight saving I'd guess.

...& potential for over 350 bhp (but for how long?)

For £7.5K Id go for the 250bhp Audi lump.

The Honda is great but its still only 200bhp for £10K...and a 3 month engine warranty

I have the TT230 kit on my car - its been great over the last 25K miles (no doubt Ive tempted fate now the warranty is out !) ..but I didnt pay nowhere near £10K for it - sub £7K at the time (due to existing mods) and considering it was gonna cost me £5K to get 200bhp out of a K series with no warranty and a lot less torque it was the best option for me back then.

I wouldnt spend £7K now 'just' to get 190bhp...or £10K for that matter for 200bhp ...I think you need more than that to really get the 'wow factor' from straight line acceleration - if thats what you are after

Guys
Regarding the Busa engined option, has anyone any idea how strong a 350BHP turbo engine would be. I am looking to buy a new Exige and am thinking of re-engining my S2 111S and setting it up for track work. Just wondering if it would be a case of a re-build every 3,0000 or 5,000 miles or is it much more fragile than that. many thanks.

I'd guess it'll be fairly fragile - that kind of power out of a small engine with a turbo on the side comes at a cost. The site says it's in development - might be worth getting in touch and finding out what kind of warranty you get if any.

yup - and thats a £4500 conversion, on top of the price of a Busa engine + fitting it into an Elise ...its not going to be cheap!

It's a kinda expensive exploit of that's all you're after . . . it's a still a 4 pot . . . it revs a little higher . . . it's not so very different . . .

Not really . . . If I had a desparate need to have the most powerfull Elise on the planet then I guess it would be an option, personally I don't (And to be fair that's perhaps why I don't understand your point :-)).
Next . . . I don't have an unreliable K series . . . and I know a lot of other people who have tuned, reliable K series . . . lots of them, they thrash their cars on roads and tracks all over the UK/Europe . . . the cars are not unreliable . . . they drive to the circuits, they drive home, year after year . . .

The "K series is old, unreliable and useless" myth may be true for a tiny minority . . . but it's a myth for the rest of us . . .

Sounds like we're back to the old 10k again!

yup ! - there is no cheap big BHP option !...if there were then everyone would have done it by now

I'll stick to my tuned up K series - 230bhp, 48K miles, 4 trackdays, 5 airfield days ...no probs ...(he says running off to find some wood to touch)

Sure you replace the k with a 'reliable' honda, but in so doing you have to install a load of parts made in low volumes to a recipe of their own devising. That probably offsets things a tad

Agree that TT have priced themselves out a bit now. Honda solution comes along and they put their price up. Go figure...

Noble are hitting 30k now btw! (except don't get a 2.5 so you need to budget 35k really)

Hi Bogie, ive read the reviews on the tt190 and saw there was a 230bhp conversion too, I always thought 230bhp must be too much for the k-series engine to really handle.

Im glad its been reliable for you, but can you give us an indication into performance stats, and are there any downsides? (please be as unbiased as poss)

well performance is pretty quick its easy enough to do 4.5 to 60 and sub 11secs to a ton. Guess if you really tried hard all day and was brutal you could get down to 4 secs and 10secs to a ton. Top speed (I have longer 5th gear than std S2) Ive seen is 150mph (on GPS as the S2 speedo only goes up to 140mph ) with the roof off, 2 up and full of luggage....it will maybe pull 160mph with the roof on and a bit of a run up

Downsides - there arnt any major ones. Fuel economy at best is around 30mpg on the motorway...drops severely on track to like 10-15mpg though.

Maintenance intervals and servicing are the same as std (youre not having to rev it to 8500rpm to make the power - red line is at 7250) but you have to have the supercharger belt changed and it stripped and serviced every 60K miles.

The biggest downside is the cost - its very labour intensive to do the conversion and takes around 2 weeks for 1.5 people to do it (one guy full time, the other for a week) the clam has to come off to fit the extra chargecooler radiator and oil cooler up front...along with pump and associated pipe work. The head is ported and rebuilt to higher spec, bottom end is rebuilt etc etc. Heres what you get for your dosh:

Ported head with upgraded springs and bigger exhaust valves
Piper 270 cams
Forged shortened rods
Forged pistons specifically for turbo charging
2 extra fuel injectors
custom cast manifold with charge cooler
160 throttle body
K&N filter
Emerald ECU
Charge cooler radiator
Oil cooler
Rotrax supercharger
Water pump for charge cooler
sports exhaust
cat rep pipe
optional 4-2-1 manifold
plus other bits n bobs

that must account for at least 50-60% of the cost, the rest is labour, profit and a 24K mile comprehensive warranty.

If you already have any of the above they will reduce the price somewhat.

Its probably the best conversion in terms of power/torque there is for the K series..but also costs the most dosh - you could nearly have a low mile Honda engine put in there for the same price...the choice is yours
