Hi All.

I absolutely love my Triumph Spitfire!

Except the engine. And the transmission. And the electrical. And several of the ancillary bits.

The car is a '72, and I bought it from a the wife of a gent who passed away shortly after disassembling the whole car. This wasn't a problem given it's not my first Spit. Or my second. It's the third. The first one I did a "refresh" on when I was in high school. The car was only about 10 years old then (it was an '80); new paint, interior, trans, differential and body-off-frame clean up. 2nd Spit was a '78 I bought myself as a toy. I ended up building a fuel injection system for it, including the intake, controlled by Megasquirt and Spark. I still have this car, but there is a tiny man with a hammer inside the crankcase who gets angry and bangs on the engine with his hammer when I start the car. Or I have a rod knock. I haven't looked yet.

The 72 is getting a GM 2.2L L61 Ecotec and a T5 trans. It's not quite as tight a fit as PB, but it does present its own set of challenges.

To be quite honest, I have NO IDEA why it took me so long to find PB. So many of the things Nik and Richard are doing are the kinds of things I want to do to my Spit... but with a tiny fraction of the talent. But now that I have watched the series, it has re-lit the flame to get to work on the car again. I also plan to shamelessly steal some of their ideas. 

 

There had to be a bump in the bonnet if the engine was to not leave holes in the road.

I'm an electrician by trade; wires don't tend to worry me.

As you can see from my garage I may suffer from some kind of mental disorder.

Also, when cats learn to drive I'm totally walking all over their cars.

GRC PB would be the ever changing "PROJECT BINKY":

Well, let's keep this in perspective - it took me 4 years to find PB in the first place...

I've been a member of the forum since 4 months after it was founded, just a little slow in my old age. ;) On the other hand you probably didn't even know you were looking for PB until you found it! (Welcome aboard!)

You're right; I didn't know I was looking for PB specifically - but they are doing the same basic thing I am, and it's kind of difficult to find people in that genre: Making old cars more like new cars, but not "hot rods", per se.

I figure the next generation of Hot Rodders will be Millennium type kids who want their car to be cool, and do the things their phones do. Digital dashes, touch control everything, even electric drive eventually - but you don't often see tech articles on retrofitting ABS or infotainment systems.

I'm really looking forward to where they take this project.

LOL @ GRC & PB!

If you're looking for something to keep your interest going in restomods (between "PB" episodes) check out the guys at Old Bones and Retropower - particularly the Gordon Murray mk1 Escort video series

 Agreed, I think I know why, just found out Bosch has an ABS Retrofit kit online and its $8000 US!

So there is! http://www.bosch-motorsport.de/media/msd/downloads/archiv/bremssysteme_2/ABS_M4_Manual.pdf

And you CAN buy it! https://www.racedatasystems.com/products/bosch-motorsport-abs-m4-kit

£6,557.28. $11,153.44 Canadian Dollars HAHAHAHAHAHAHA

Well that's just hateful. That's like triple what I've spent on the whole car so far.

So mostly it seems to be justification as to why one might want to adapt something they took from the wreckers. That manual gives some nice clues as to what you might need to have to get a Bosch system working, and by extension what kind of vehicles you might want to try and source your ECU from (Similar size and weight). The trouble would come in the tuning for your specific vehicle; wheelbase, track widths, CG, weight, etc all matters. You might be able to retrofit something that technically works, but might do sweet diddly to improve performance. 

Still.. I'd love to try..

 As if to add salt to the wound the Bosch system is NOT street legal per the manufacturer.

Adapting what will come from a donor is what I had planned as well. I had planned on using it as an ABS only system. With the difficulty of implementing it at all I may as well try to include VST functionality.

It seems it will be some order of magnitude harder than I had imagined.hmm

If we could get our hands on the config software it probably wouldn't be that big a deal. Mess it up though, and the results could be catastrophic. And I'm sure it's pure liability that forces Bosch to say their aftermarket system isn't street legal.

Being that it's for motorsports I seem to recall reading that the software to calibrate is included.

For the price they're asking I would expect software to be included.

What would be REALLY nice to have is software that could calibrate production parts. Bosch MK60 ABS units are pretty common (BMW, Audi..), and look pretty much the same as that aftermarket kit...

CAD Design. I didn't end up using it because once I had it to test fit it was clear it wasn't going to work. But that's the point of CAD, right?

Are you using standard Spitfire Mk4 rear suspension?

Well.. for now, anyway. I may in the future switch to something different, perhaps rotoflex based with a Subaru diff or maybe something different entirely. If I do go that route it would have to be with CVs and not the rubber donut.

I made the decision a while ago that if I was ever going to be able to drive this car in my lifetime (and in my budget) I'd have to stick with the stock rear for now. And truth be told, I like the way the rear handles as it is - it's only the differential that I'm not happy with.

I have gone with swing spring and the later, wider axles and all GT6 brakes. We'll see how long the diff will survive; probably 100% right foot dependent.

One step closer to the edge!

For the first time ever, power (sorta) from the engine turned the rear wheels. Unfortunately it was just the starter motor, but we'll take the wins where we find them.

Cooling system almost done, and thank it wasn't nearly as tricky as PB. But no AC or boost make it considerably simpler. The hose clamps I've used aren't ideal, but they are what I have right now.

Not bad for a temporary dash I think.

Is vibration going to be an issue with the weld on the long pipe off the coolant tank?

It's made of some pretty heavy material, so probably not.. but I'm going to change it anyway. I have to pull the header tank off to make some other mods, so I'll change it then. In the meantime, it's working - so it's a little low on the priority list for now.

Been working on the tans tunnel... it would be really cool if BOM did some CAD tutorials.. :D

Agreed, Fusion 360 is beyond both me and my PC, BOM CAD is more my speed!

It looks as though you've got a handle on it!

I use Solidworks at work (occasionally).. but it tends to be significantly more precise than the car is.. haha!

Had a render done on Fiverr to help me decide on paint.
