can anyone help me or link some pic's of what step's i need to take to install my racingbeat header and silencer on my 85 gsl-se,i dont have stock cat's on my car anymore but i have the stock exhaust peice that go's over the rear axle,i still have the stock air box and i still have the air pump hooked up.

 

you might need a stock airpump because the presilenser uses that and if the stock ones are gone you might not have all the pieces, but usually you undo the assembly form the stock midpipe and the 4 bolts holding the manifold and the O2 Sensor and just remove all that and replace it with the header and presilenser and reconnect everything like the stock parts.
hope that makes some sense to you and helps

 

It's really just unbolting the stock pieces and putting the Racing Beat components in place. With the presilencer, you're going to discard the Air Control Valve. The air pump won't be hooked up to anything afterwards, but keep it there because its belt also helps turn the water pump.

Do you have new exhaust gaskets?
How about a shop manual? Here's a downloadable version, it's useful to know how much to torque down the bolts.

 

so do i need to block anything off at all?

 

YES you need to block off the ACV ports or it will not run and probably leak coolant. The header SHOULD come with a block-off plate kit. Its really a simple job.

Also, the presilencer does not use the airpump, I don't know why that was said.

 

I don't believe coolant runs through the ACV since it just redirects air from the air pump to the cat, exhaust port, or to the intake. There will be a huge vacuum leak if it's not blocked off.

 

????????????

How is is going to leak coolant?

You block off the ACV as in singular.

Look in the FSM for the location and what the ACV is.

You can either leave the Air pump in place or remove it. I have never had an issue with belt slippage when i have removed the Air pump.

 

Seconding this. This thread is a wealth of misinformation. The Doc is right, you should take off the old exhaust manifold and install the header. If you want to remove the air pump, you will need a block off plate for the Air Control Valve, as well as a cork or something to plug the stock airbox after removing the air pump hoses.

You *can* leave the air pump installed and just plug the air supply tubes that went to the old cats. I did this and didn't remove my air pump for a few years without issue.

 

 

my mistake i guess, i was told it did but i never used the presilenser, i made a custom piece

 

Sorry...I was thinking there was a coolant port there too.

 

so in ray green's pic is that 2 self made block off's?

 

I don't think so. It looks identical to the one that was supplied with my RB header. Did you buy yours used?

 

yea i got mine used,it came with no block off's

 

There might be a template to make your own on the racing beat web site. I believe its 1/8th steel and wouldn't terribly hard to fab (or have fabbed)

 

so in ray green's pic the upper plate is the block off and the lower plate is a heat shield correct?

 

Yup. Racing beat does sell it for $15 or something. You can also make one.

 

yea i went ahead and ordered the block off and heat shield from raceing beat didnt wana have to mess around with making one
woot 100th post

 

The racing beat heat shield will not clear the stock nikki intake manifold. The one shown is from re-speed.

 

Heat wrap ftw

 

Shield = Respeed
Plates = Racing beat/mazdatrix

 

 

humm the guys at raceing beat told me that the shield they are selling me will work on my 85 gsl-se 13b

 

ok take a look at this http:www.racingbeat.com/frmazda1.htm i think i made the link right part number 16219

 

Or you could make one out of a sign. Amazing how after almost a year, the paint is still great.
