LQ4 into a 3rd Gen/1972 Nova by frojoe

OK, so after a long lull, mainly because of school, I have a couple updates!!


First thing is an update of the braking/steering system, I've decided manual 4-wheel drum brakes just aren't gonna cut it, so until I have enough money to do some disk swap, I'm just gonna throw a booster on there. Also, I can turn my car with the flick of a pink no matter what speed I'm going, talk about no road feel!!

I found a Hydroboost from an '06 Colorado for $100 at a local truck junker. I'm gonna combine that with a Heidt's power steering adjuster valve so that I can fine-tune the feel of the steering wheel.

I also had a new line made for the high-pressure side, it cost total under $20, which sure beats buying $18 3ft of Russell braided PS line, and $13 for each of the Russell PS fittings not to mention having to make it myself!!


This is a horribly-taken pic of the new steering line setup with the Hyrdoboost..


The Hydroboost unit itself...


Went to a local hydraulics place and had myself a new hi-pressure line made...

The line uses 37* JIC female fittings, which were $5 each, and $7 for 3.5ft of 4500psi 3/8" hose. Fittings look like...

And next was a revision of the fuel system. I've mentioned the general idea of it previously in this thread, but here is another description...

Fuel gets sucked out of stock tank with stock fuel sender, so that I don't have to modify the tank or shell out $$$ for a stainless one. However, this poses a problem 'cuz the fuel sloshes around a lot, and we don't want that beautiful LS engine to get starved.

So, I have a low-pressure (carb) electrical fuel pump suck gas out of the stock tank, and pumps it to the front of the car. This gas gets dumped into a skinny but tall fuel "surge" type tank with an outlet at the bottom of it. Now assuming the tank is not even half-full, in order to starve the outlet at the bottom, the car would have to be doing way over 1g laterally, or be upside down (), so this should be plenty fine. A Walbro 255 pump feeds off the bottom, and pumps into a Corvette FPR, which has a return going back to the fuel surge tank. The surge tank has another outlet, a fuel return going back to the stock car gas tank.

Crappy pic of setup...

Pretty, pretty, fittings...

last but not least, this picture was too cute not to include..
