C20LET powered, rear engined rear drive mini project

[KSM Engineer]

Not strictly a Vauxhall I know but plenty of Vauxhall parts in there! Just a few pictures of the progress made so far.




Spec so far is a tubular steel manifold, GT28RS, piper cams with verniers, F28 2wd converted box with paddle clutch and custom shafts, standard ecu at the moment but about to install an omex 600 pack, JE pistons and arrow rods and loads of other stuff that I've probably forgotten. Ultimatly we're looking at developing the engine up to around 550bhp with the addition of a bigger turbo, most likely a GT35 or 40 and we are also working on modifying the flywheel and gearbox input shaft to run a HKS clutch pack.

I just finished looking at the carlton and then i see this lmao, looks to be an awesome build, love how far the rear wheels poke out aswell , will you be competing in anything with this?

[Nemesis]

will you be competing in anything with this?

National "barbecued arse" competitions?

[rc]

fapping hell, thats a squeeze in there, great work and the fuel system in the front is a work or art in its self

[daddy cav]

This will be good .

[dearing5]

thats funny mate, nice

[Gazdaman]

National "barbecued arse" competitions?

And National "How fast can you lose control, spin round and face the other way" competitions?

Gaz

[Soul]

National "barbecued arse" competitions?

lmao Best have some major heat protection goin in there

[KSM Engineer]

Cheers for the comments, I agree its going to be a bit twitchy to say the least. Even though the test engine thats in at the moment is only running around 350bhp, the short wheelbase and heavy arse will make for a very challenging drive. Once the engine work is complete I'm going to fabricate the rear bulkhead so as to avoid any crispy buttocks! I've got another LET that I'm building up at the moment which will be the actual engine that goes in at a later date. The target output is 450 - 500 bhp which combined with the low kerb weight should make for a rapid quarter mile. Hopefully those big back tyres will help to put the power down a bit!

[Soul]

Even at 350bhp i bet thats still an animal to say the least lol. Any idea what sort of times you want for a 1/4 mile?

Looking forward to the progress from this keep us updated

[dewismotorsport]

awesome little build will be savage with 500bhp with less than 800kg wet

[KSM Engineer]

It'll certainly be a bit nippy. Quarter time I'm hopeing for an sub 10 second if we can get decent traction. Not sure how long the box will last to be fair as the last F28 I pushed past 400bhp lasted about eight and a half minutes before it dropped its internals all over the A127!

Stuart Meads has a sub 10 sec mini using a zetec. I went out in it when it was running a 320+ nitrous 1.9 CVH! rapid doesn't do it justice. Most scary car i've been in.

[Soul]

Sub 10 secs would be awesome looking to keep it road legal if ya can aswell?. Oh dear lol bet that made a nice mess, you near southend way by anychance fella if ya was going down the A127?

[Nova88]

His Mini pinned me in my seat when he nailed it, doing a NOS demo for me. It was sooooooo quick! Then when he backed off he said "sorry mate i didn't have the NOS on!!!" Jesus it scared me minus the 150 nos injection!!

[Add_Gee]

Are you on 16v Mini Club ?

If not have a look :-)

[Kev_G]

that looks like a weapon lmao

[KSM Engineer]

I'll get some more pictures up when I get a bit more done. In the mean time hers a few pictures of an MK3 GSI Astra that I worked on a while back. The customer got a bit carried away with the boost controller, 2.2 bar on the tell tale, with rather catastrophic results!




The top photos are from before it suffered engine failure, the ones below are the aftermath!




This happened in third gear on full boost at about 65mph. Shame really as the car was pretty mint and had great potential.

[CAH.]

Looking like an awesome build man!

Like the mk3 astra too.

[chip]

Cool mini.

although it even makes my nova easy to work on.

make sure you look at strengthening the block if you are going for 550bhp, quite a few of us have had failures of the cylinder walls now without going much past that

[dearing5]

wire brush on them pistons... no worrys lmao

[vantastic007]

My uncle suffered a broken con rod in the middle of nowhere, so he dropped the sump, lopped off the broken conrod, stuck a jubilee clip round to stop the oil coming out of the crank journal and then struggled home on three cylinders. Luckily the block was no too damaged!

Great, super, smashing marvelous mini BTW. :-)

[Soul]

Lol spose you should be carefull trying to boost 2.2 bar lmao what sort of spec was that let running?

[TigraTurbo]

Great projet!!!u think its gonna need wheely bars?

[KSM Engineer]

Lol spose you should be carefull trying to boost 2.2 bar lmao what sort of spec was that let running?

At the time it was running piper cams, GT35 hybrid, omex management, stage three head, JE pistons and the rest of the spec I can't remember to be honest! It had a E Boost 2 controller fitted and the customer had a fiddle with it once he got used to the output at 1.7 bar, hence the damage .
