Oh and I think I used it for tapping the rear side valve cover too.

tapping it for what?

FWIW a 1/2" NPT tap can be used without needing any drilling.

I ended up using 1/2" NPT as well for the turbo drain in the oil pan so it wasn't a one-time use item for me.

I thought so, it looked like it. looks like I'm in the market for a 1/2" NPT tap now...

For the heater line you could drill-tap the LIM and use a 180* fitting.

that's what I've been thinking I'd have to do, I just don't have a tap that big, and I don't want to buy one for a one time deal...

drilled the oil pan for the drain



worked on the ICM bracket



I need to figure out how to get this heater line bent 180* around, so it points towards the front of the car



the other one was easy, cut, weld. done.



and now for shots of the intake manifold, got air?

intercooler HE lines installed, on the left is the line going to the HE, on the right, is the return line, that also supports the battery cables.



I re-did a couple things on the hotside, routing is still the same, but I ditched the upper mount for the turbo, and made another leg on the lower mount, so the turbo is now supported better, with less bulk, and allowing for more clearance around my shifter cables. I also installed a second V band on the front side to aid in install and removal.

I mounted the wastegate today too, it's mounted under the turbo, with the dump pointing towards the outlet of the turbo, it will dump into the exhaust stream.






it doesn't look like much, but it's been alot of work...

I wasn't going to install the lines tonight, but I changed my mind and did it.... here's a pick of the original lines I made, and the new lines



the far right is what I made the first go around, next to that, farther away, are the front hardlines to the HE, then the two main lines that run beside the tank. I'll try to get installed pics tomorrow. I also made a set of hardlines to run from the tank in the back to the intercooler/retun from the HE. the flat pieces on the right side of the far right pipe hold the battery cables in place.

as of now, the intercooler plumbing forward of the engine compartment firewall is complete. I also did a little bit of work on the exhaust and turbo mounts, I decided it was time to simplify a few things, unfortunately, I didn't take any pictures of that.

intercooler water lines are pretty much done, needs paint, and the rear line (to the tank and pump) need to be mounted, and I need to find a low profile elbow to fit between the tank and the frame rail... DOH! I should have pictures tomorrow showing everything done.

[ericjon262]

Here's a before shot of the intercooler lines.



here's what will be going on the car (they're not quite done yet...)



the big plate in between goes under the gas tank, the pipes will have plates that bolt in place under that plate.

3/8" fuel like will support up to 550 HP, when used with fuel injection at 44.3 PSIG, IIRC.

I'm going to go talk to one of the local (well shit the only) dyno tuners and see what he thinks, I'd prefer to have a cushion, if the number is 550 hp, I should be ok, I don't plan to be north of there, but the build (short of the cheap turbo) should be capable of more than that, and I have it apart already, so it wouldn't really be any significant work to upgrade now compared to later.

I got word that the intake is done at the welding shop! I won't be able to pick it up until friday at the earliest, but they said they were closed, so it looks like monday...

the intercooler lines were done, but I'm going to make a few changes. originally, I joined the two pipes together for ease of packaging, but the ease of packaging comes at a price. The hot coolant in route to the heat exchanger will warm up the cooler coolant on the way to the reservoir, so I'm going to redo them apart, and a little bit different too. right now, they are a little too long in the front, and bend up at too sharp of an angle in the back. I'll post pictures tomorrow when I get the new ones built.

I'm also entertaining the idea that I might run a bigger fuel line, stock is 3/8", I'm thinking I may step it up to 1/2" while I have the tank out. it depends on what size the outlet on my fuel pump is, but I don't have it in yet.

price is right, and a guy on PFF had 3rd party flow charts comparing it to a walbro, and it outflowed the walbro by a longshot.

some of you DOHC guys would dig his build....

intake is getting welded up tomorrow or wednesday, I'm going to talk to my machinist and see how much longer on the rest of the engine tomorrow.

in other news, the intercooler lines are almost done, just need a couple more fittings and a little bit more hose, should have pictures tomorrow.
