Last night I started cleaning up the inside of the driver side manifold. I was working on the collector and I wasn’t happy with how the #1 tube merged. I had put a radius there when fabricating the header, but the final result wasn’t great and unfortunately ended with a right angle for the...
Yeah, when Chris asked about flexes, that was a “DUH” moment for me - especially since the crossover is going to be stainless. That’s why these threads are the best - you smart guys catch me before I make a mistake.
Here are some pics. This flange is one I had made for me locally that was a copy of the ones you can get online.
It could use a little touch up with a grinder to get it to align properly.
Yes, I can definitely get you some better shots of that for you. I should be able to this evening.
I don't see any reason why dual crossovers couldn't be done. I was mindful of the firing order on the turbo side, making sure 2&4 were on one half of the turbine and 6&8 were on the other side...
Pretty different. I didn’t like how number 5 cylinder was done on the Hummer headers, plus I wanted v-band flanges and I wanted to control the routing of the crossover, so for those reasons I decided to make my own. Ironically, I also don’t love how I did number 5 on mine, ha.
I got the driver side header put together. For some reason it took almost as long as the turbo side, even with 2 less tubes. I think I’ll have less to clean up on the inside of it though.
Next up is the crossover.
I did some looking at how low the upper radiator hose runs and quickly realized the fuel filter was going to be a problem. Luckily I already had to run some 6mm spacers under the AC compressor so the Sanden compressor would clear the bracket, so I was able to move the bracket under the...
The turbo header is done until it’s time to paint. I added more weld to all of the seams, which isn’t as pretty, but that allowed me to safely clean up the inside of all of the tube mergers. I used carbide burrs to clean everything up.
I also added bungs for the pyro and drive pressure gauges.
Last night I swapped the pulleys on the AD244 alternators to the correct pulleys for 88-95 so my tach will read correctly.
I measured for a belt once those were on and found a cheap 119.5” belt on eBay I’m going to start with.
I should share one more thing I did this weekend since I think it’s going to be best for me to keep the thread up to date as I make progress and then do a catch-up post on the engine build portion later.
I didn’t want to put crappy looking injection lines on my freshly painted engine and I...
Also, I found out the hard way that Dorman hinge bushings won’t stand up to this tool - the force eventually breaks the cheap bushings apart. I’m going to be putting Cunningham Machine bushings in it this time.
