What are you guys using for waterpump/ heater hose fittings. I just got a new waterpump and it needs 90 degree fittings where the heater hoses attach. Right now the one on the car has some plastic pieces friction fit and I want something a little better. Was thinking AN 90's with pipe thread, but what size?

Street and Performance has some fittings on page 82 of their 2006 Catalog. I copied them in the picture below. Hope that helps or gives you some ideas.

Thanks, I just found those about an hour ago. Can't believe they want over $40 for each of them. There's got to be a cheaper alternative.

you can remove the steel nipples and drill and tap for pipe thread. very easy.

That was my original plan to use pipe to AN fittings. But I have to use 90 degree fittings. Is there enough room between the fittings to spin a 90 degree fitting around?

Use 90 degree swivel adapters, or straight fittings and a 90 degree hose end.

I knocked out the steel hose barbs and welded on some AN #10 fittings. I've then got a couple of 120 degree Earls hose ends and 5/8" braided hose. The aluminium AN #10 weld on fittings are anly a few $$ each and any good welding shop should be able to weld them on for you.

LS1 Cobra - What did you use on the other end of the hose where it connects to the heater core?

LS1 Cobra

The connections for my heater core don't extend through the fire wall. I got a pair of AN10 bulkhead fittings and modified them (I haven't got any pics of them installed yet). The bulkhead fitting has a male AN10 on each end and is threaded in the middle so you can put it through a hole in the fire wall and secure it with a nut. The longer end on the inside of the firewall I machined down into a barb to suit regular 5/8" heater hose. in behind the dash I'm just using regular heater hose to go from the bulkhead fittings to the heater core.

Trick idea on the coil packs!!!

I wanted to keep the engine bay as clean as possible so machined up some aluminium brackets for the coils and re did the loom.

Here's a pic of the coil brackets:



Here's one mounted in the end of the foot box:



I'm getting a set of custom length leads made up shortly. just got to get my headers baolted on again and measure them up. It'll be interesting to see how they perform.

I tapped each hole 1/2"NPT and then used one 90 ell (AN-10 to 1/2NPT) and one straight (AN-10 to 1/2NPT) then used one straight, and one 90 degree AN hose fitting. Just be careful tapping out the smaller of the two holes. I ruined one water pump b/c the casting cracked; newer water pumps (04 and up) have more meat in that area and I had no problem (with the newer pump)
