I just pulled the rear end out of the old GSL-SE. Out of the IT car and to transplant into the GT car.

I thought now that I am changing classes I could add some camber. I had been told...

Depending on the track...My GSL-SE gets killed or is somewhat competeive. Perhaps it's my set-up and / or driving, but I find on the tracks that are real tight, I get eaten. The horsepower...

Mine was driver's side. This side takes a real beating on curbs that you basically launch the car in efforts to straighten out the chicane.

I'm not sure about most, but it looks as if at least three of us (GSL-SE) have had this happen.

I'm not sure if the 14"/15" tires make a difference. I might be more along the line of rim offset. ...

I was just scanning through the Tirerack website and found that Avon has entered the DOT R compound tire market. They look mighty close to the new Hoosier.

Has anyone tryied them or heard any...

I am using 2 MSD Blaster SS coils, and a MSD 6A on my 85 GSL-SE, and I have had no issues over the last two years.

I am not set up as a direct fire, that would be illegal for IT.

[This message...

Although I feel that the question is quite clear...illegal.

But if Mazda was just to supercede the whole 13b, and show the renisis engine as the new replacement block...That would change a couple...

Yes, it was more for a pre-oiler. And this would be for a streetport 13b that has high pressure regulator and high volume oil pump. Basically what I am building is a EP 13b.

I haven't splurged...

I use Royal Purple in the eccentric shaft case and redline synthetic 2 stroke in with the gas. I was using Amsoil up until last year where the local supplier of Amsoil almost doubled the price. I...

Is there not a different exhaust length for different engines? With my rotary, the distance to merge from each rotor is very important.

The engine builder I spoke with regarding my exhaust...

I have to chime in for the Carbotech bandwagon. I run Panther XP on the front and Panther Plus on the rear on my GSL-SE (RX7) that weighs in at 2530lbs. My fronts are lasting approximately 16 hours...

Is a Accusump worth installing on a rotary? How many use them?

Thanks.

7's....In the photo of your dual setup...Is this a separated duals (one pipe for one rotor), or do you have a merge location of the dual pipes and it then separates back to duals?

Under the rear...

Chris, How are you keepin? The chisel / hammer method works great if you roll the car out of the nice warm shop and let the car outside. Once the undercoating gets cold (froze)..It breaks off in...

I've been following this thread for quite some time. And it seems the biggest concern is that allowing a larger diameter wheel (while maintaining same existing width) is going to change the race...

Here's one more...

Brooke...Shouldn't you be off at the beach? (of course...just watching the waves...)

I have a magazine, but don't remember the name. They did have rebuild kits listed, and I have a rear caliper...

Just to add a comment about the premix oil...Yes, you can use synthetic...Just make sure it is a synthetic two stroke oil.

My OMP puts out basically the idling amount of oil. I run a Synthetic...

What I have been using as my shift points, is that when shifting up I want the torque peak somewhere close to the RPM of the next gear. Yet again my fuel injection system (1985 GSL-SE), those piddly...

Oh ya...Rotaries can cavatate the water pump real quick. By throwing on the smallest drive pulley (on eccentric shaft, sorta the same as the crankshaft) and then large pulleys on the waterpump and...

Yeh...There's not too many of us that decided to run the 1984/5 GSL-SE in ITS or IT-1 here in western Canada.

In Calgary, we have Canada's longest front straight (approx. 3800 ft). So as you may...

I just have to say Thanks for posting this topic. First off, I am glad nobody was seriously hurt. But this topic does remind us (drivers) that there are risks on the track. I like to think of them...

The only thing I can comment on is the high rpm driveshaft vibration in 5th. Assuming your 5th gear is .824...That amounts to a 1.214 times your rpm. So your driveshaft is only spinning at...

As someone has mentioned already. Check out Susko's website (G-Force Engineering). There is a section on Mazda Suspension, where his book is listed. I can't say I have done everything in the book,...

Speed?.....What Speed???

I may have gained 4 or 5 hp from the exhaust changes. I still need to find time to do some dyno runs for fine tuning with the new exhaust. I'm guessing there may be...
