JL Engineering Bi-Turbo 3.0 Project+full chassis refurb

Hi John,

Very nice work! Did not forget the details! Nice project!
If i'm asking very gently...as your box is in bits, could you post a pic of the inside of the bellhousing???

Regards
Chris

Car is looking awesome, is it pink or is it still red and thats just a trick of the light!

Hi Martin, should be out at Croix. Are you sure its pt no. 77 03 090 245 that apparently fails? Groove and hole look the same. Ratios are different.

Hey Clee, I'll send you a couple, owe you one for getting me that linkage bush when mine gave out at Bruntingthorpe. Whats your address.

Looks like we'll be going with the steel turbine wheels now so big boost can be an option.

Hi Chris heres some bell housing pics, sorry a bit late dont get on here enough..



Hey Tony, Yea its had a neon pink wrap with dragon graphics on the bonnet

Cheers, John.

Hi John!

Thanks for the pics, now i know how it looks inside, thanks Lee also again for the measure, now i just need the distance from the clutch spring, to start calculating, Martin will help me there.

More pics, project moving on nicely.

Subframe all assembled with new bushes. All parts media blasted, Epoxy powdercoated rather than painted for durablity and excellent finish. Waxoil injected before assembly.




Genuine Alpine bushes...





Hubs sanded back and POR15 process applied.




Rear suspension back on car.


Refurbished starter motor.


Powdercoated rocker cover


Turbos on ceramic coated manifolds


First fit of engine, right rocker cover just a temp while the other is having breather fittings tig welded.


Billet air intakes arrived today so can start to plumb in the twin chargecoolers.


I've simplified the water feed and returns, Safrane one piece waterpump retained to eliminate any rubber hose in the V.

Few more things ready to fit.


The actuators needed modifying as the compressor housings have been clocked to a new position. Brackets and actuators then cleaned and POR15 coated, ready to fit.



Driveshafts cleaned and POR15 coated.


Twin chargecoolers with basic boost pipe layout. Now making brackets to fit.


As its a new install we didnt want to run with the 20+ year old knackered loom, so the engine bay is being treated to a complete new loom. All new sensors, plugs, connectors and various gauge wire has arrive so work can commence.

We are also running wasted spark so that will eliminate the problematic rotor arm and distributor cap. Makes for a cleaner looking install too.



Picked up my new toy. Looking forward to making some billet ali brackets on it soon!

kin-ell have you or Dave won the lottery

That all looks bob-on John Are you running twin pumps and rads for the CCs? Think you'll need to

.

Cheers. Running single pump and rad with the twins. Charge temps will be lower than with the single turbo setup running the same boost so the current CC rad will be up to the job. Running out of space for oil cooler/rads etc.

Havent had much chance to play with the lathe yet, will give you a call.

Heres the new trial fitted rear brakes with the seperate handbrake spot caliper. These are the 335x30mm drilled straight vane. Final fit will be 330x30mm grooved and spotted, curved vane.



Heres another pic to compare size with original disk.


Cheers, John.

What is the KG weight of the original Brake Disk and the upgraded unit?

Hey Simon, the new setup only works out 1.5kg more than the standard setup per corner. Most of this is the rotor as the calipers are very light.

Got the water pipes tailored to fit the engine bay, just need to tig on the fitting for the header tank and thats another job out of the way.


The new loom for the rear of the car is coming together nicely. The engine bay is almost complete. Im really happy with it so far.

This was just the beginning of the spaghetti fest.


Some of the finished loom.



Ecu mounted and additional in car wiring being layed out. Some modifications to the seats had to be made to clear the Ecu and flying lead but now its all in you cant tell anything other than the original renix is lurking behind the seating..


Next job is fabricating the chargecooler hangers and making lots of brackets!

Hey Simon, the new setup only works out 1.5kg more than the standard setup per corner. Most of this is the rotor as the calipers are very light.

really my kit for the spider is a kilo lighter than the original setup,

so you've gone backwards instead of lightening the unsprung weight to improve driveabiity you've added weight

[stephendell]

Billet 4's are significantly lighter than Monster 6 but I guess there is the extra weight of the handbrake caliper to account for. Also I noticed John had the pads, brackets and bolts in the new set up when he weighed it and think the old ones were out. Rotors are not the final fit or size so he should re-weigh when the smaller curved vanes arrive like for like.

Guessing probably not possible to go from 259 to 330 without adding some weight though. Spider/A610 has advantage 300mm disk is much heavier to start with and calipers are bigger/heavier too. Can't see Porsche dropping down to piddly GTA size disks to save a kg per corner.
