Project Supracharger

It looks awesome mate, no doubt. Will a TT cable be long enough?

Yes I think it would be, and a T.T. cruise cable too, but I haven't been able to find any used ones.

I know its a bit late now, but yesterday I found that nice throttle body I mentioned!

Is it worth making up an engine loom and fitting it to the engine all fed to one connector , then fit the other end of the connector to the oem loom , so just one simple disconnect to remove the engine and all new wiring in the engine bay , seeing as you have set fire to yourself and sliced wounds in yourself , you might as well go for the hatrick with electrocution

I think these supercharger conversations people are doing are fantastic

Thank you, but now the Lexus one is shoe horned in, it's staying there.

The only mods the engine loom will need is to extend the wires to the TPS and ICV.

I will do that to the car engine loom so that when the conversion goes on it will be plug & play.

Thank you for the TT throttle and cruise cables.

You wouldn't happen to have an M112 bypass valve gathering dust too?

This conversion 'conversation' will soon be torque talk.

I need the crimpng tool to change to the old type of HT lead connectors and fit the pre 92 4Runner distributor cap.

Does anybody have one I could use?

I have man flu and don't feel up to much, but can't leave it alone.

So to scratch the itch, I have in supercharger readiness, extended the wires for the ICV on the GE loom and tied them back out of the way.

Only a little job, but one less to do.

I am still scratching my bald patch re. the bonnet!

I have been looking at this Do-Luck version, I reckon I could save reinventing a wheel and mod the inside of this to clear?

Does anyone have one of these to sell, or trade with a U.K. spec or J spec bonnet?

A slight change of schedule.

I will be fetching the donor N/A trans tomorrow.

Will see what I can do with the hybrid this weekend.

nice work so far mate good luck with it ,

It turns out that the ebay vendor of the donor N/A trans was club member comorin219, thank you.

He is quietly tinkering about in his garage upgrading an N/A block to T.T. spec and fitting it with a big single.

My original plan was to encorporate the splined N/A tail shaft which would have allowed me to use my new one-piece aluminium prop, which in turn would enable me to switch between N/A and T.T. Torsens for sprint or top speed.

But the price for the engineering was more than buying 2 Torsen diffs and 2 propshafts.

Plan B.

Keep the T.T. tail shaft and use a T.T. auto prop and diff, it makes the job a lot simpler too.

(I later found it better to use an N/A 4.083 Torsen diff with a T.T. diff prop-flange)

The spring sunshine was lovely today so I have performed this Supra brain surgery outdoors in field conditions.

I have transplanted the N/A valve body, gearbox loom and cable line pressure control into the T.T. box, and tapped a hole into it's bellhousing for the cable mount.

Et Voila! The A340E-GTE/GE Hybrid is born. A 500+ ftlb transmission, compatible with N/A electronics and cheap as chips.

For this application the line-feed pressure control cable needs to be 2" longer to reach the Lexus throttle body on the supercharger conversion and now that I have one to use for a pattern I will get it made, the whole transmission upgrade will then be complete and ready to go in.

This plug & play unit will be compatible with the N/A ECU and/or Suprastick manualised control and will be more than strong enough for the job.

This hasn't been done before, I have worked this out by myself.

Here are the 2 victims! T.T. A340E GTE top (with flange) and N/A A340E-GE below (with splined shaft and line pressure control cable)

Fluids drained, then steam cleaned - They both look very worried! (Note: N/A left has J1 bell-housing, T.T. right has J3 bell-housing)

T.T. A340E-GTE layer 1

N/A A340E-GE layer 1

T.T. A340E-GTE layer 2 (Note 5 solenoids, there's another located under 2nd from left)

N/A A340E-GE layer 2 (Note: 3 solenoids)

T.T. A340E-GTE layer 3 (The actuators seen on the right are removed and shimmed to increase shift speed and firmness as required)

N/A A340E-GE layer 3

Layers 4

The Hybrids new brain

N/A A340E valve-body, loom and line pressure control cable transplanted into T.T. A340E-GTE.

All done and dusted, it's now a Plug & Play upgrade (Note:J3 bell-housing requires a hole drilling and tapping to locate the line-pressure cable)

(Either N/A or T.T. dipstick can be used, but it must be paired with it's original correct tube)

Does anyone have one of these to sell, or trade with a U.K. spec or J spec bonnet?

No, but if the uk bonnet is White I'd buy it off you so you had more funds to buy a new one

Okay

looks like the car is really starting to advance well! looks a little daunting, lol, but great to see its coming along.

The job list is getting shorter.

Now the weather has steadied up a bit, I will start doing a few jobs on the car, there is a lot to do.

As soon as I have the cable, I will swop in the complete new transmission and install the w/m pipe whilst I'm under there.

I want to test out the Hybrid and set up the Suprastick before fitting the supercharger.

Today the new bypass valve arrived, so I go the Main Dealer at Northamptonjam and see.

My reception was a little 'cautious', I was the bloke who had critisized the quality of Jaguar engineering.

Nevertheless, it turns out that the new one has the same flaw, they must have been cast from the same incorrect pattern mould.

I have been hand tailoring the butterfly in the original valve with some fine wet and dry paper, I gave both valves a blow job and found that I had reduced the leakage in the original to around 25% of the new one.

The original valve is the best by far and it's going in.

2 silicone elbows cut to match the odd lengths on cooler and some serious little clamps form a sound and squidjy mounting.

I put some waterpump grease on the butterfly it before it went in, it's now 100% efficient until that wears off?

I may have found a bulge donor!

It's the perfect size, unfortunately it's steel not aluminium, but doable.

Fitted the Lexus wheels.

i thought that landrover panels are alluminium aswell.

i thought that landrover panels are alluminium aswell.

I went into the Landrover Main Dealers and asked the salesman, from the brochure he quoted "all aluminium body panels", but on inspection I found that it is made from steel.

Now hunting for a dead one with an unwrinkled bulge to play with.

I can feel another hybrid coming along!

Looking at fitting the Land Rover bulge backwards onto the Supra bonnet then using a scoop from either a Cooper S or Pulsar on the front of it?

dear god please do not use the pulsa one, a prelude down my girlfriends way has one on it and it looks cr@p! i found this pic the other day i though you may like it....

didnt think this looked to bad

I much prefer the Cooper S scoop, which would look similar to the one in your pic.

I like it, that is the sort of thing I am looking to make, but with a wider bulge.

Thanks for that, where did you find that pic, interested to learn more about it?

mini cooper scoop sort of
