QLers with Retro Motor cars

[Pr0f]

My Gen 2 RX7 convertible is in several pieces in the garage, loft and some bits in the house. The old shell had rusted through, so I found another carcass in good shape and made the decision to take every bit off her and refurbish - it's a daunting project and it ebbs and flows - life gets in the way so much.

I am working on building a custom ECU based around propeller 2 chip for the old girl when she is reborn.

Will post a piccy later when I am on the other laptop

the old girl was a lovely drive - was running close to 300BHP at the wheels, but the front bearing sleeve spun blocking the oil way there, and the engine ate itself at the front rotor, a sad day.

Lesson learned though - when doing an engine rebuilt - replace EVERYTHING tha is involved in rotation! Amazingly all the apex seals survived the failure. It was always quite amusing to drive up to one of the local boat suppliers to get my high permormance marine 2 stroke to put in the seperate oil feed for the oil injectors (provides clean oil to them rather than recirculate engine oil), the engine was very clean with very little carbon build up using this method of lubrication, the only downside was a waxy soot deposit around the exhausts on the back bumper

I bet it sounded lovely too!

It sounded best with the racing beat exhaust - when the back boxes failed at a weld, to get it through an MOT I put a single exit 'drain pipe' with a strange bung thing that could be easily remove - with that on it sounded like an angry draggon, but this exaust killed low down torque at the expense of freeing up the turbo at higher rev levels, giving crazy mid to top end. But not really legal on UK roads and dificult to even cruize past a horse!

I have reworked the exhaust for when it goes back together - using the same 3" down pipe, and existing mid box, but now the Y splitter goes from 3" to 2.5" x 2, and between these ends and the backboxes, a motorised side vent will be used to allow the back boxes to be kept in circuit or the exhaust to exit straight to ground - the ECU will control the motor via a small table, so that at low rev's the back boxes are always used, and at higher rev's you have the option of direct venting to provide more power at the top end - usable on the drag strip but not for noise controlled racing courses - this also means I have basically replaced all the non stainless pieces of the exhaust system with free flowing larger bore stainless.

love the modified mini !!

the problem is that i can not weld ……………

That's what I thought too - but after picking up a cheap gas-less welder that can also use gas bottles, I played about with a couple of pieces of scrap and - low and behold it's not dissimilar to soldering on a larger scale!

Cleaning the pieces before hand is essential, and clearing away anything that is likely to melt or burn if left in too lose contact (so if doing floors in the car, carpet and sound proofing stuff has to come out or be moved clear!)

Then it's about keeping the welding gun steady when moving so that you create a flowing weld - seemed to work for me - you start to get a feel for it has really gone into the join or just sitting on the surface and not providing a good joint.

I haven't tried much with aluminium yet - this is a lot softer and far easier to 'punch' through!

like screaming rotaries toooooooo

The mini is my project during the lock down, trying to get stuff bolted back onto it, after years of being in bits.

If you hurry up, you can still catch up with Project Binky

or good 'oll DORIS , and the Pie-Van
