Hello Adam, Thanks for the input and positive comment. As can be seen in the pics, whether it likes it or not, the t.b. will go where it fits in this scrapyard jigsaw puzzle. The pipework between t.b. and s.c. has an i.d. 5mm larger than the t.b. and the flexi vacuum hose forms a nice 'flowing' bend. Pre t.b. will be an 80 to 102mm 90o silicone elbow, directly to a K&N filter in a cold air fed box similar to my present set up. Bearing in mind the limits of the T.T. auto transmission, I think there will be more than sufficient breath from this arrangement to have it worried enough. Next job is to raise the top of the front leg by 11mm to achieve the finished height, and to weld on the t.b. flange. Having different manifolds on the engine and jig is a PITA, I shall be pleased when the sky hook guessmeasurey is over and the bracketry complete. Dave, Thanks for your 'vote of confidence'. Yet all l I have achieved so far, is to reduce perfectly good components into a 3D jigsaw puzzle, and set myself on fire. I am looking forwards to nailing them into place.

That bracket looks a right dogs breakfast, and no strut ring fitted either!

I spent this afternoon fabricating the induction plumbing and flanges. It turned out that the steel I had found was not mild, but tempered. It cut easily enough with a 1mm disc so hadn't noticed, yet boring the holes took ages. The blade was old yet I was getting suspiscious, then when working it with a grinding disc it became obvious, especially when I set myself on fire with the 'cold sparks'! Looking on the bright side, I can be confident that the flanges won't twist.

Kevin, Cheers for the encouragement, there's a long way to go yet. Shane, I am confident with all aspects of the design, except maybe asking too much of a 6 rib belt? Yet should that be so, it won't be difficult to upgrade to 8 rib pulleys. Regarding your cast pipe; I still have a hankering to include that, but not sure where? Next time I call to check out your coffee making skills, I will take a better look at it. Maybe I can cut out the 'pretty piece' and have it welded onto the front of the charge cooler?

If you have a TRD strut brace, you can do it like this and save yourself a few pints.

Hello Matt, It is 'coming along' very nicely, thank you. Although backarsewards really, because when completed, the conversion can't be fitted until I have built the hybrid transmission and modified a bonnet.

Been looking at pre-formed alloy bends to fab the induction, but at over £30 each and 3 needed, after paying to have it welded up would be around £200 for half a metre of pipe! Have decided to fabricate the flanges from some scrap plate, use a piece of stainless pipe left over from the exhaust system mods and then form the complex bend with 76mm vacuum hose. The pipe can then be welded in to become part of the bracketry. Unorthodox and lots of filing, yet free.

The Lexus t.b. has at last turned up, it only took the vendor 23 days to work up the enthusiasm to lick a stamp! The good news is; it will fit in a treat, in the on car mock-up pic, it is propped up on a pile of rags to somewhere near it's new home. I am pleased with this find, as I hadn't actually seen one, just chose it from looking at pics of t.b's on the net. Smaller on the outside, and larger on the inside, it will get smaller still as I prune off the parts I don't need. Had another on-car test fitting and found that the bracket was too tight against the manifold and also needed the s.c. plate level raising by 10mm. There is now plenty of clearance, and there will be a little more when the supercharger is not hard up against the existing N/A t.b.

In this pic you can just see the 'foot' I have added at the bottom/back of the plate, to bear onto the machined 90o face that is common with the blocks, added diagonal bracings and cut the leg to a line to marry the supercharger mounting plate. I declare the front mounting leg, an immovable object.

I tacked the next section of Corolla in place whilst the bracket was test fitted on the car engine, I have formed it with 5mm clearance to the fanimold. The finished height may need to go up or down a 'little bit' ? and a lot of the steel will come out to make room for the throttle body but it is starting to look more like a bracket than a brake disc. The back of the supercharger is only hanging on a tube spanner, but it is good to get to see a few of the pieces getting closer together.

Best I correct 'surestick' to Suprastick before anyone gets any ideas. Happy New Year

I have had another routle around under Bobs' bench and found the 8mm steel I needed. One slightly used 1972 Toyota Corolla brake disc, the steel is in good condition and it's getting recycled, it fits well and the form allows clearance to hose and clip. Happy New Year

There you are Barney, hope you approve Under the bench I found a small piece of 8mm steel with holes in it and routled around and found enough washers in the right sizes, so have used them to form the top/rear mounting plate for the bracket.

Thanks for the input Barney. I routled through the bits box and found 2 nuts that were 1 size to large for the stud, these are held in place in the hole in the 6mm plate and true to the face on the block using a 12mm nut, once welded on and given a makeover with my new angle grinder, it will be the same job done different. The mounting bracket must be good, I have several ideas on how to fix to several bracing points, but until the throttle body arrives for me to build around, I am restricted to fabricating component parts in readiness. I opened up the centre of the plate to ventilate the belly of the charger, there is steel to be added as it goes together, but it will need to be 'efficient' to allow room for the induction.

I have been out playing with my new angle grinder. The supercharger mounting plate gets a pruning and I have made a few modifications to get the induction elbow to go on up-side-down, but there are more mods needed yet to simplify the plumbing. The 3 threaded holes in the block are not on a level plane, the pieces to fabricate a bottom mounting plate are in position and ready for welding.

I can't answer that question, but there will be someone on here who knows. I have the complete U.K. set ready to 'plug & play' into my N/A as part of my Supracharger conversion.

Get yourself a U.K. spec fuel pump - Denso 300 lph @ 43.5psi, it is a 'plug & play' fit, pumps more than the Walbro, is quiet and more reliable.

Take a look at Barney Brendans "N/A supercharger build" thread, he has done that to his.

'Ingenuity' I have sufficient, and the 'skills' that I don't have can be rented, however, the 'good luck' would come in handy with the weather, and any element involving the input of others. I am itching to get on with the project, yet grounded until either the seller of the Lexus throttle body works up the enthusiasm to lick a stamp, or the elements allow me to work on the car without frostbite. I conclude that 'determination' will be the most important quality. Merry Christmas

What you propose makes perfect sense to me, which is most probably, why you will most probably find that it has been circumvented within the small print. Don’t for one moment think that any insurance company exists to do you any favours. Their aim is to generate maximum profit for shareholders and employee bonus payments.

Just spotted this on ebay buy it now for £25; could do someone a favour. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170572115423&ssPageName=STRK:MEWAX:IT

Fuel octane/RON is an equasion with ignition timing. To use higher octane with the engine tuned for lower octane will give no advantage, as it is the advanced timing that gives the extra power, not the fuel. To use lower octane in a engine with ignition timing tuned for higher octane will cause problems with detonation, not serious in the short term with N/A engines, but can destroy a forced induction engine during one 'pull'.

95 RON is fine for an N/A with ignition timing @ 12o BTDC. I am running my N/A on 99 RON with ignition timing @ 19o BTDC.

Excuse me, but we are in different time zones here, and I must get up early tomorrow. If all else fails and you become convinced you need an ECU, or any other used part for that matter, contact Keron, link below, he will get any part to you for far less than you will pick it up in the U.S. http://www.mkivsupra.net/vbb/member.php?676-keron
