I knew people would start looking at this engine. LS400 are easily found for around 1000£. They are expensive to insure, quite thirsty, some would say
ugly and dated, and nobody wants them. But the V8 could easily get a second life in the kitcar industry. Nice and sorted project in the link, but
going for 19" wheels seems more bling than sense...
Now we just need some reasonably priced conversion kits, for transaxles and normal tranmissions.

Hello Claes Yes im still in progress it's been on and off progress(tough going)! Should see my car soon mapped and running ready for final
touches and GRP body panels. Talking about set up: Im using Turbo Supra 5 speed manual gearbox(strong old box but you will need a adaptor plate with
bellhousing from LS400 automatic box...etc)-there are different solutions out there too. Engine managment is LINK XTREME-it should take care of most
things but it will need to be mapped. Oil filter location is another problem that has to be removed to different location and of course no AIR CON and
POWER STEERING for that you have to use different pulley and belt that cancels it all out. Engine sump is standart you wont find dry sumps for theese
engines(ive seen in life half done dry sump conversion kit but due to costs etc it's never been finished)...there might be some in Australia,New
Zealand or so. In my case with 17" wheels and some sump guard plate it will be fine for ground clearance and i dont think it would affect much
acceleration(plus i like wheel arches to be filled) Exhaust system is all custom(all Lexus standart manifolds from Soarer,LS400,Cressida...etc are
crap they are so restricted and due to available engine bay space need to be customised)....i went for polished stainless steel Ac Cobra
"style" side pipes with proper manifolds no cats but with sensors left in headers for better fuel economy etc. Air intake will be pod
filter engine mounts are standart Lexus LS400(new) short turn steering rack around that lump..... Using a Ford Sierra 4x4 rear diff should be strong
enough for time being(hope so). Basiclly all engine set up is standart with a bit of luck it might push around 280 engine hp on dyno in best scenario
depends how much life was left in it and will show if i done everything right! I wanted to mention that CAMS in this engine are not made for
performance....very flat torque curve but it all can be toleretad for a start. With decent engine breathing it will still rev happy past 5000 rpm(in
standart car power drops) without loosing much power till 6500 rpm in safe way without any mods+ it will be relatively light car. P.S. All performance
cams,lifters,even ITB kits are available for this engine on internet bet they have to be imported from STATES or Australia.....for thoose who think is
not enough I hope i've gave you some idea-welcome to comment and ask

I binned the stock management and went with a mega squirt running wasted spark with two ford coil packs . Crank trigger is the one off the later Vvt
engine and the flywheel you need it the 3sgte with the holes slotted by a couple of mm with supra arp flywheel bolts . I have the cad file for the
adaptor and use a rev 3 mr2 clutch fork and ball to keep the slave external .
As mine is twin turbo I drilled the fuel rail and manifold to take some Saab 360cc injectors
The stock exhaust manifolds are a terrible design but the width of the motor leaves plenty of room to build a tidy header .
Using an adaptor plate leaves the guide tube for the clutch bearing a bit short so I added a 30 mm sleeve to keep the bearing centred .
My worry was paying a lot for an ecu that relies on ancient hardware to run properly as a new or used maf for an ls400 isn't cheap where a ms
set up is map Tps based with cheap generic sensors

Holy s...
Froggy..you must have a deathwhish. Are you planning on 335 slicks?
Are you guys using the Haynes chassis? Any strengthening done to suspension or frame?
I assume the supra gearbox is the one from the old 3 liter. Can those still be found in reasonable nick and for a reasonable price.
Still..I want to go midi...don't tempt me :-)

Twin turbos!!!!!!!!!!! SHIT........crazy man. I would go for supercharger would be more user friendly...unless you planning to do some serious drag
racing. Yes box is out of older Supra i choosen it cos i could get adaptor plate for it,flywheel,clutch(new) and rest of bits....... Theese boxes are
quite rare now....been used in lots of applications......you could easy pay for one at least 700£.. You can use smaller Toyota Supra NON TURBO box
too......if you can get adaptor plate made or bought....for lighter car it should be ok! My chassis is made from Haynes Roadster book.......bit wider
for comfort and at first i wanted to put ROVER V8 in it...... Other worries was body panels........wanted to fit them and not to go aluminium route
cos lots of theese "shed" built Locosts...etc could be very ugly and i hoping to for normal(not some 750-800kg) end result too!

My chassis is a modified Mk Indy which is a metre wide right up to the bulkhead and I've put the tube back in under the bellhousing to stiffen
it up plus the centre spine will be a lot taller as you sit a lot higher up in a rod
I've also got a mid engined transverse set up car with 500hp which is fine on track but not as much fun as a front engined rear drive car on the
road .

[youtube]http://youtu.be/ysdtAVapKyM[/youtube] or http://youtu.be/Oc5C3hQEuFs I was talking with guy.....he runs standart internals on that
engine...low boost and twin turbos......there are another 7 project his mate doing it but he went atmosferic way.........it revs over 8000rpm.. - some
mad thoughts and engineering gone in that Lexus engine..he had it mapped couple weeks ago and now it's ready for body work. I could add some
fotos but im not worked it out HOW yet! I was uploading some but something to do with Chris from forum...i just don't know why.. I cant even
upload fotos of my car appart from this one in early stages.

Unbelievable how ugly a 7 can be made to look...
I am not looking to build a dragracer which is why the geometry is quite important. If it fits in a standard Haynes chassis, made for a pinto engine
which is heavier than the Lexus engine, it shouldn't be a problem.
Then its just down to aerodynamics if you want a higher top end speed. What full body options are available or modifiable for a Haynes chassis?

It should't be a problems if the job been carried out properly...my mate years ago was running in similar chassis Rover V8(actually one of the
first V8 locos in UK)....it didnt twist,break or snap......lots of people can over do strengthening too...you end up with heavy-ugly car still with
it's own limitations and on top of that you have to put some nasty body panels. High speed aerodynamics ar poor as we know but 7 type cars never
meant to be modern day GTR I worked out gear ratios on my set up and in theory it should go up to 172 mph....i don't know in practice yet if
it will be enough power,guts or other aerodynamic aspects involved....that's not my worries at moment. You can easy order body panels online or
seperate bits if you want to.......they doing lots of carbon bits too. As for drag racing...i think most most 7 style cars run out of gears before
they reach 1/4 mile that's why times not that brilliant(traction issues too) Ive seen Duncan Cowper(Haybusa engine F1 hybrid turbos 500+) and
some other mad sevens in drag races...they run around 12 sek which isn't that fast considering standart R500 could be a bit faster! On another
hand there was guy in Sweden he had a Turbo Volvo engine(car has on big boost over 500 bhp)...he run in 9 sek and other guy in UK with Chevy V8 he ran
similar times.......in his Dutton!

I know I can get panels for a seven style kit car, but wondering if there is anything like the AGM just a bit prettier out there, that will fit a
Haynes. Not looking for high speed for dragracing but for the end of the straits on tracks like nurburgring GP, where the 7s always loose all they
gain in the corners

How about Radical then? .....Or put some Honda K20 series engine supercharged or turbo charged.....or both together in your Elise with some TIME
ATTACK style splitters,spoilers,diffusers.....im sure you will be faster on Nurburgring than old Lotus design!

Not touching the Elise...its brilliant as it is. Looking for something like the Coram LMP. Unfortunately, as far as I have been told, they went bust,
and moulds destroyed.

Not so sure...Steve Turner picked that project up and the Turner Automotive Design website is still active...

use an Audi Transaxle, The 01X i believe has been used successfully.(hurts me to use any Audi part on my car). Interesting fact about the Exige. It
probably means that scaling up the S1 chassis is possible. Looking to fabricate uprights as well, so can even adjust the them to fit the 10%. Now just
have to clear the calendar for the next 3 years(yes, I am slow. The MK took me 4 years to finsih :-) )
