LSX / Supra classification

     Latest issue [July '14] of Rod and Custom has an article on building a custom twin exhaust system for a 6 cylinder.  Sidebar shows how to cut, rotate, and reweld mandrel bends to make everything up [including an X pipe] without a bender.  Well worth a look, the basic methods can be applied to any custom system.

     Most advise locating the O2 sensors/bungs between either the 1&2 or 10&11 o'clock positions for optimum results and sensor life.

I added airbags front and rear to my car to get ground clearance.

They were supplemental to the suspension I raced with, the car was not drivable on the street without them.

Yarrr thats where I was, undriveable.
Now i have lifting blocks in the lowered springs, and the ride went to hell, but i can make it over most obstacles without that old hotrod scrape.
I figure i can drive to wilmington, jack it up and remove the blocks for racing.
this setup should allow me to rookie up and buy more time to get the exhaust into a proper shop.
I also found out the rev limiter is set at 5800....   stupid base tune

Thats a good place for it until you get pushrods.

stupid car
every time I fix one thing I find two more things wrong.

[redhotracing]

Oh... wait until you start RACING it. For every little thing you'll need several hard to find
$300 parts to meet each and every one of many many many requirements... And (hopefully)
you'll love every minute of it... after you get some speed under your Acura, that is 

[greenjunk]

$300?  I'm at $1000 per item.  I guess thats why i'm still faster than you luke

[redhotracing]

Hahaha. That's right, Dave.

Yes, I recall at Maxton running into town on various occasions and buying spark plug wires, spark plugs, a starter and a water pump. Do you know what a pain in the arse it is to swap out those things on an LT1 Firebird at the track??? (boo Optispark! )Welcome to racing!

[redhotracing]

We had to have our valve stems replaced,
change the water pump, weld up out chute
mount, fix the torque arm. Maxton in July,
~100 degrees in the shade 

[yarp]

why so many water pumps?

[redhotracing]

Water pumps break sometimes. See my previous
post about LS pump cavitation at higher RPM's. It
just happens sometimes.

Where?

You should check out the Meziere Belt driven water pump for the LS engine. They are used on a lot of Off-Road trophy trucks.

I have my heart set on a meziere electric, since I also have an electric MR2 P/S pump on the shelf for phase2 of the project.

I now have 2.5' of exhaust clearance and haven't scraped on anything in the last 4 shakedown drives.

[redhotracing]

I've heard little good about the Meziere pumps for
LS motors; why (and no $) we don't run one. If you
under drive the pump (15% IIRC) it works great and
no cavitation issues. I haven't seem their belt driven
pumps; may be worth a look. I know that Moroso was
going to release an adapter for BBC electric pumps,
which are much cheaper, to LS motors. Saw it at
Autorama a few years back, haven't checked on it
since...

Good job on the exhaust! It's the little things that help
us keeping working at it... Good luck in Ohio.
