Nothin' wrong with that... it's all the mindset. If someone's an arrogant a**hole, I don't care if they're 50 lbs or 500.

38mm SSautocrap wastegate is on! I opted to dump the fumes back into the downpipe to keep noise levels down... the welds aren't the prettiest, but they're strong. Still not that bad for my flux-core birdshit welder, though.

I also fitted a radiator from a 4.0 Explorer... I tried to mount it as high as possible since the cap is mounted right on the endtank... not sure if it will work as planned, but I'll give it a shot. The pressure cap is a little higher than the highest wet point in the engine, so I think it should be alright...?

Good to see progress - no reason this car can't be in Carlisle in June.

But I'll ask these questions any way....

What's up with dumping the gate right in at the elbow at a 90-degree angle? I guess you'll have plenty of room for improvement on v2.0.

What was the reason for the Explorer rad?

Does the Holset "like" a bigger oil feed for some reason?

I wanted all the wastegate plumbing to be as compact as possible... and frankly, I'm not TOO concerned with the 90Â° intersection - I believe this wastegate should be large enough to prevent creep even with a restriction like that in the dump tube.

It's huge, aluminum, cheap, and widely available. My stock radiator was trashed when I went in the ditch, I gave my parts car radiator to QuirkyMerk, and I sold my Saab radiator to a woman at work who had crashed her Saab and needed a replacement.

If the Exploder radiator doesn't work well, I'll be replacing it with the SSautochrome RS500 replica (and their matching intercooler.)

It had a 3/8 tube going into it in the stock application... the only 3/8 inverted flare adapter I could find for the inlet was for -6AN... if it's too much flow, I guess I'll end up blowing out the seals and having to rebuild the center section, in which case I'll also make a -4AN line. I've got materials for a -10AN return line in the mail right now.

That Exploder rad looks like it's taller but narrower than stock, right? That might come in handy if you're looking to do a FMIC and you need clearance for the pipes on either side.

Are you skipping a coolant tank? If so, and you want to make sure the air is purged from the coolant, you can go with my red-neck swirl tank solution - a $5 HVAC vent valve from Home Depot, plumbed in-line on one of the heater core lines. It's now been road & track-tested!

Heater core lines?

Hmmm, yea, looking again at the placement of that WG, looks like you may have some issues plumbing in a line to the heater core. Are you going to skip heat entirely? Dude, you practically live on the North Pole!

The car isn't driven between October and April.

Colin is that the LM1 WB your using?

I read a post or two on TF about how the LM1's dont like the high EGT right at the turbo outlet.

I like the Explorer rad setup!!

I only see a 1-wire O2 sensor in the pics.

FWIW, I have my Bosch WB sensor bunged-in about 8" down on the DP and have never had it error out.

Yeah, that's just a stock replacement oxygen sensor for mockup. I was planning on using the LM-1, but maybe I'll have to put a little more thought into its placement.

Worst case scenario, I'll plug this hole and put a second bung further down the line.

More random crap pictures!

I got a downpipe done... I just hacked up a Cummins downpipe for the ball flange...

AN fittings are awesome.

Gauges in.

I also took a couple of pictures of the headlight brackets necessary for the euro lights, since I haven't really seen them posted anywhere:

Got my timing tensioner finished up... and switched from the Stealth 3.0 SOHC belt to a 4G63 belt.

Get'n er done!

What's that timing belt tensioner from?

Is the water pump pulley from the EDIS Ranger?

Colin · Post by **Colin** » Sat Jan 21, 2006 10:21 pm

Belt tensioner is stock Volvo with one side cut off and a piece of steel welded to it. Thankfully, the pulley itself is replaceable, so I won't have to modify another tensioner plate when this wears out.

Yeah, that's the EDIS w/p pulley. I'm still not 100% sure I'll be using it... we'll see when I get a serp pulley on my alternator and stuff.

Okay, but the bearing itself isn't stock Volvo DOHC. Hell, it's made in Japan! Don't ask why, but I have two of the Volvo bearings hear in my office.
