Engine conversions for Exige/Elise S1 and S2
Discussion
seen the 350bhp version with a Rotrex style SC - well theres a trial car out there....not seen the 500bhp version strangely enough ! ....mmm...500bhp from a 2.0L SC engine....mmmmm...yeah right !
personally, 300bhp reliably from the 2.0L K20A engine for 60K miles + is better than 350, 400, 500 that only lasts 10K miles

bogie, who said you cant have a reliable 400 or even 500bhp from a 2.0 ltr?????
have you not seen modded Evo & scoobies???
ok you would need a built bottom end but thats about it. the K20 is an amazinf engine and very strong! i think it would take it no problems
Chris.
ps. you also have to remember the dilivery of the Rotex is very "soft". you only reach peak boost at the red line (or just before) and the torque is normally quite flat so there isant the instand bang of boost like you get with turbos or roots blowers!

Ever seen the service interval on a 400bhp evo VIII? The other issue is that they literally have no power below 3000 odd rpm. Not ideal for a light car like the elise - you will lose the back end every time the turbo kicks in. By all accounts Bogie's 300bhp is plenty enough.......well at least till he finds something newer and better.

define 'reliable' ...I do 20-25K miles a year...to me reliable is 9k mile service intervals and 100-150K miles with no problems
most of the big power Scoobies and Evos are like 4.5K intervals, rebuilds at probably 30K miles etc
To get more than 300-350bhp out of a K20A then youd have to go turbo and fully built....lots of money and unknown territory whereas a theres thousands of people out there with 250-300bhp supercharged K20's some that have done 50K miles post conversion no issue..
Yes - anything is possible, but at £13K for the conversion, then to start ripping it apart and spending another £10K for a (potentially) dodgy 350-400bhp just isnt worth it to me

Andy Walsh has a v8 based on 2 bike engines that produces 420bhp. He is taking the same engine and supercharging it and putting it in the back of an Elise. 550bhp
Only £20 - 25k
I want one. After Walshy took me out in it, nothing else will do. Anyone got a spare £25K lying around. Possibly alongside another £40-50million

yeah your right the servise intervals are like 4.5K aren't they??? but then i have heard alot of people chance the oil and filter at 5k anyway, regardless of the service intervals!!!!!!
on the spool up thing, yeah the FQ400 was sh!t, but thats not a problem with a supercharger now is it???
and if a Busa with a turbo can make a reliable 400bhp then i think a 2.0 ltr K20 would beable to! lol

Still waiting on the Lotus Exige RST-V8(2.4L) the firts 2 letters are even the same as my name, René Stam RS ...now where is my money to order such car sadly I'm not that rich to just order such thing, so have to wait a few years for a second hand??
Only heard they put one in a Elise...like to see it sitting in a S2 Exige

Though this "Elise" has a very fast V8 but its the GT1 elise not for the road sadly
stil a nice picture
Lotus Elise GT1. Only one road car was build by Lotus and it wasn't this one. The Lotus Elise GT1 shown in Paris was a race car in Frank Muller livery - yellow over black. We were told that the car is not one of those which raced in the FIA series. The car is said to be chassis number eleven complete with carbon body, carbon brakes, 6 speed seqential Hewland and a Lotus V8 twin turbo with nearly 600hp.

"and if a Busa with a turbo can make a reliable 400bhp "
who says they are reliable though?...I know people with normally aspirated bog std Busa engines in Westies....10-20K miles seems to be the norm before they go pop/need a rebuild !
building a small engine with huge bhp/ton is easy...making it last isnt...isnt that what F1 engines are all about?

I look at that picture and whilst the sillouette is elise-esque I wonder how much Elise is there left, so is it really an Elise or a custom built car of varied provenance ?
Gets me to considering at what point through modifications is a car no longer associated with the original car, e.g. I look at touring cars and see rough production car outlines but hear that they have like 1% of components in common, so whats that about ... do gullible consumers associate them with the sh1t they buy in the showrooms ?
Sort of grandfathers axe question if my father replaces the handle and I replace the head is it sill my granffaters axe ?
Just wondering.
Hi Hans, its a officialy a race car GT1, only one was build for the road, the rest was build for racing...
The car on the picture was also a special build but not for FIA racing I believe, and I think the one road version is a black car?? I believ also a dutch guy drove a car like that...? Jan Lammers I think but not sure, anyway a lot power in such light car
GTRene
you also can read a bit more about it here;
www.pistonheads.com/lotus/elise/Default.asp?storyId=4764
this is the V8 engine Elise GT1 also one roadversion
and this the only road going Elise GT1?

Oke its told many times before, but I wanted it in this thread also, the RST-V8 you can get them in 2? known variants? a V8 2.0L and a V8 2.4L the 2.0 I have a videolink from that engine but sadly not in the Elise but in a radical, but just listen and see how fast this 2.0 V8 320hp engine is

RST V8 from Russell Savory of Motopower
First up is the RST-V8 created by well known bike team Motopower run by Russell Savory Tony Hart (F1 engine builder Brian’s brother) and Titan Motorsport have been working on resurrecting it. The test unit is fitted to a Caterham SV, weighs just 74kg and is amazingly just 19in high, 19in wide and 19in long, while kicking out a conservative 340bhp and 190lb/ft torque. The RST-V8 is based on a pair of Yamaha YZF1000 EXUP units although the only original parts remaining are the cylinder heads although these are scheduled to be replaced by bespoke parts soon. The engine has a flat plane crank, which synchronises the firing pulses in opposing banks of cylinder banks, which aids balance. Price for this one starts at £17,625 inc VAT, although you can specify roller barrel throttles and other items if you desire. We’ll be testing this unit in the Caterham SV shortly, and look forward to it, but thus far the engine has done 12,000 hard driven miles in testing without mishap. Visit www.rst-v8.com
I like to see that in a Exige S2 soon anyone have a video of a Elise or Exige with this engine? or a picture?

dont get too excited...people have been talking about putting that engine into an Elise for over 2 years now and still no-one has. Sinclaires were going to do one..but I think even they had to re-consider when coming up with a good business case for actually spending £100K + developing the kit and making it work to maybe sell 2 or 3 conversions...great for a show car...but hasnt happened yet
for most people spending £25K on an engine conversion on an Elise is out of the question..especially when you can get 330bhp from an Audi 1.8T easy enough (albeit about 40Kg heavier) for £11K ...compare that to 320bhp and less torque (but lighter and 8 cyls) from the RST and it dosent look too good value.
Its a shame really..would be nice to hear a V8 Elise (other than the GT1) but I dont know anyone daft enough to pay for it to be done

LOL ..yes - they do..its all about marketing...people do really think that their road going Astra or Scooby is a proper BTCC or WRX car im sure !
