i dont know about "best" but if i had the cashola i would get a tilton double disc setup and flywheel. definitly handle the power and abuse you can dish out, and you just replace the metal friction discs. if you cant afford that i would say a chromoly flywheel and a ACT clutch,

 

tilton sells a flywheel with that clutch setup. and who selss chromoly flywheel

 

well i dont know i lucked out when i got my motor from corksport who just happened to have a mazdaspeed 12lb chromoly flywheel minus the counterweight. talk to some japanese rx7 guys, i have (tried to) read a few rx7 tuner magazines from japan and they have like 30 different flywheels and clutch combos its just finding a way to get it from point A. to point B.

 

When converting a GSL-SE 13B engine to a later year 13B Turbo engine, is it possible to retain emmissions controls so that one may pass state inspection?

 

yes

hmm whered that post go?? i am going to try and keep this thread clean and too the point, if your going to ask off topic questions post a new post.
thank you drive through!

 

By the way,

For you guys in the "Boosted Circle" I posted over 60 pics of that 12A Turbo that runs low 10's.
good helpful, handy stuff.

All Kinds of pictures, from every angle.

They can me seen here

BTW, Full Boost Magazine from Australia wants to do an article on it, just from the notoriety it got on this board.

Pretty Damn Cool if you ask me.

 

Just thought i would let everyone know that i am takin your guys advice and scrappin the 13bt idea. not for lack of funds or for any of the other reasons that i were told to stray me, simply because................im getting a yamaha r6!!!! so if any of you guys see me out there on an r6, prepare to be spanked, peace
mike

 

What tranny are they using that requires that kind of shifter placement?!?

 

Jim, much of it was covered HERE.

I suspect that you subscribe to this thread, and don't visit unless someone posts here...

You really should visit more often...We value your opinions.

But to Summarize,

The car has a 1985 Supra Transmission with a Datsun Live Axle Rear End.

 

Actually, I'm not subbed to that thread. And I spend a lot less time on the Forum than I really should I guess. Too busy running my family, my club and my "transplant headache relief plan" (means: non-RX-7 related things) to get on here too much lately. And the page and a half o' post whoring on that thread is one of the reasons I don't sub to too many threads any more. Just not enough time in the day to read a bunch of " " posts...

Thanks for the info though. That's a mad quick FB yo! I'll try to be better about the hangin' around.

 

Allright, so I was showing my current project to a good friend of mine, who happens to be quite a good wrench in his own right - (on domestics).

He liked my setup so far, liked the trick/hidden place where I put the three MSD6AL's, the Haltech, Gauges, and he was going over the brakes and asking what pad's, rotors's etc.

He then asked me If I was replacing the stock GSL-SE Brake booster (which works off vacuum) with one from a Turbo II (which would accept positive pressure/boost.)

I told him that I don't think I need to, and with all the research I have done, that I haven't heard anybody mention it before, not even once.

He insisted that when he's done Turbo conversions, he's always had to do something about the brake boosters on N/A cars.

SO HERE's THE QUESTION:

To be able to stop properly with the brake assist, do I need to change anything regarding the brake booster in order for it to accept manifold boost pressures?

Thanks.

 

i really dont think so, i asked a few people about it and looked at turbo 2 boosters. they have a built in check valve but think about it when do you use the brakes? not on boost so the motor is normally on vacuum. there are a few turbo cars running with the stock booster and yet to see any problem, but it is a good question.

 

That's what I think as well, any of the other Turbo FB guys could chime in?

 

I got on the bypass and did about 120 mph just trying my new legs LOL and I had no problem stopping...

 

The line running to the booster has an arrow on it telling which way it is suppose to be hooked up. The rubber line has a check valve in it. If your line does not have the valve in it, you will need to get a one way valve for it if you go turbo. With out the check valve the booster will see boost and it will pull on the master cylinder causing it to squirt brake fluid out of the master cylinder’s reservoir air bleed hole all over the engine compartment. Don’t ask how I know this.

How do you know this?
If you have a Turbo FB, you know that you're gonna have to share details/specs/pics with the rest of us.

That's the rule around here. Especially if you post on this thread.

 

Well, I do have a turbo FB, but it is a "gasp" piston engine. Swapped in a 2.3turbo ford. But, MIKE-P-28's rx has the check valve in the rubber line coming off the booster and it is the stock line that came on his rx. I guess I tossed the stock line, or left it hooked to the 12a I gave to Mike. For time I hit boost, squirted brake fluid all over my car Good thing the paint is crap anyways.

Alex I told you about Randy's car LOL

 

Yeah, I remember. It's got pistons. Nevermind.

 

LOL Ran pretty good none the less, and whats hes got in it, its actually kinda impressive

 

Hey guys,

I will add to these later with my own pics, but check this out:

This page will show you the differences between a 12A Gas tank and a GSL-SE gas tank.

Gas Tank Differences

You will note how the the SE tank has a "baffle" around it. Thus keeping the fuel pick-up tube from catching air and sloshing around.



You can also see that the SE Fuel pick-up is HUGE, (inside diameter larger than a -10 fuel line). Crispeed had told me all along that the SE does not need to be sumped like the other FB's. Now I see why. Built in Baffles, Oversized Fuel Pickup tube. Makes me wonder if they did all this for the Turbo 12A's in Japan.

If I recall correctly, the funny thing is I don't think the N/A 2nd Gens have such "Turbo Friendly" features..



Now you have picture proof of why I decided to not sump my GSL-SE fuel tank like this:

 

Dont run it low on gas and you will be fine. My fuel pressure is fine, and I always leave at least 5 gallons in there...

Besides where to find a SE gas tank that aint all screwed up inside?

 

Hey Alex you are mostly correct with that gas tank comparo but not all 12a's have the tank shown. All the 84-85 tanks are the same but the -SE tank has a larger suction line than the 12a. The tops of the 12a and -SE tanks are interchangeable.
