Clearances are tight (no, really) but it works. The wide section at the bottom is the front half. I'll build the back section first, then start working on the header design. I'm thinking there will be rapid visible progress with this part, which is always satisfying.]]> Mon, 15 Mar 2010 10:53:40 -0600 The MGB GT http://www.slowcarfast.com/MG/diary.php?UID=310 http://www.slowcarfast.com/MG/diary.php?UID=310 Compare the wall thickness of my new pipe to the picture of the removed part. I suspect the car is now stronger. And more importantly, the exhaust construction may now commence.]]> Mon, 15 Mar 2010 10:51:17 -0600 The MGB GT http://www.slowcarfast.com/MG/diary.php?UID=309 http://www.slowcarfast.com/MG/diary.php?UID=309 It was a very quick and easy job as I'd hoped. I had my welding helmet set too dark so I couldn't see where I was cutting, but it only took a little bit of cleanup afterwards to make everything work well.

But I'm pretty happy with how easy and inexpensive this was.]]> Mon, 15 Mar 2010 10:45:29 -0600 The MGB GT http://www.slowcarfast.com/MG/diary.php?UID=307 http://www.slowcarfast.com/MG/diary.php?UID=307 A bit too tight, in fact. When I had the new frame horns and decided to install the rad to show off to Janel what I'd accomplished, I discovered that the radiator outlet was right into the kink in the horn. Argh. So I cut that one off again, chopped 5" off the back end and spliced it into the middle. You can see the ground-down welds in this shot. There still isn't a lot of room for the radiator outlet, but there's enough. That's all I ask.

I'm really happy with this. The end result looks pretty obvious, but it took me a while to come up with it as I kept thinking "no, that's too complicated" and taking another look. This is simple, fairly light and should be decently strong. Might make a good sway bar mounting point in the future as well!

I chopped out more of the sheetmetal in the nose and tested to see how high I could put the rad with the hood closed. Had I specified the rad without a filler cap, it would have been a bit higher. Naturally the rad is just wide enough to cause interference with the structure of the hood.

I picked up some pipe with an ID a bit bigger than the exhaust OD. It's some sort of massive gas pipe, and my poor chop saw had a heck of a time with it!

The exhaust is very high on the list as it's hot and big and determines where many other things go, but before I put the exhaust in I wanted to make sure the driveshaft wouldn't cause a clearance problem with the X pipe.

The ball flanges on the right will join my headers to the main pipes, with some room for "oops". The shiny band clamp was also going to perform a similar task, but may be out of a job.

It's either that or one huge 18", and that would put the motor in the worst possible place. Given the fact that there are no heat exchangers (such as intercoolers or AC condensers) in front of the rad and pretty clear airflow, I think even two unshrouded fans like this will do the job. I'm very concerned about the depth of the assembly, as the more I push the rad forward the less hood height I have to play with - and I'm already tempting fate there.]]> Mon, 01 Mar 2010 23:36:15 -0700 The MGB GT http://www.slowcarfast.com/MG/diary.php?UID=298 http://www.slowcarfast.com/MG/diary.php?UID=298 This shipment is from AFCO. Along with some interesting suspension bits for the Targa Miata came this radiator. It's a dual-pass setup for maximum efficiency and it's huge! Seriously, it's the smallest rad I found that I thought would work and it's also the biggest radiator I thought I could fit: 26" wide and 20" tall. There's going to be some serious surgery ahead to make this work, and I think it's going to also entail hood pins. I just hope I can make it fit without hanging it down below the body.

I figure I only need 6, but more can't hurt. The MG only has about 4 and they're all devoted to lighting from what I can tell. If I only need 6 of these 10, I'll integrate the two boxes.

The grey merge collector on the right is an Edelbrock piece, one that I've used before in another build. I only have one of these.

Since the track is now wider than it used to be, this doesn't cause any sort of interference problem with the tires.

A moment with the grinder solved that problem. You can see that the stock tank is actually crimped together. I was careful to stay clear of that section.

This is far less difficult than it sounds. The tank bolts to the bottom of the flat trunk floor. I simply had to drill a number of new holes 3" to the left of the existing ones. The large hole for the filler required a hole saw, but otherwise it was quick and easy work.]]> Sat, 20 Feb 2010 19:28:23 -0700 The MGB GT http://www.slowcarfast.com/MG/diary.php?UID=292 http://www.slowcarfast.com/MG/diary.php?UID=292 Flyin' Miata was moving and a lot of random, outdated parts were being sent to the scrapyard. Well, they're not much good as is. But they do have new stainless steel flex joints in them! So I'll cut those out and use them in the exhaust system. I don't expect the engine to move much, but it can't hurt.
