Posted: Tue Dec 02, 2003 3:03 pm Post subject: Remote Booster Brake Set Up |
|
|
Guys,
I am about to embark my SR20 installation. I have most of the components that I need, but I want to install a remote vacuum booster brake set up to position the motor as far back as possible.
I have had a look at 2 other SR powered geminis, one had remote booster, the other had standard gemini brakes. With the standard booster set up the engine had to be positioned too far forward for my liking.
Searching the forum I found reference to VH44?? remote booster. Has anyone used this set up at all or know about them?
Thanks,
Matthew |

Have a talk to hopper stoppers, they can help you out with what you need to do, and can even supply you the parts that you require... Peter at hopper stoppers is a very helpful legend. |

Im just gonna get a Custom Plenum made up from an S13 as the runners come from the top, not under,
and if you make it triangular you will clear the booster and cylinder, also put the throttle body hard against Plenum and easier intercooler pipes, straight into the hole next to the radiator,
i can see it now.....

The motor I have is from an S13 180SX. It has the curvey intake manifold with the throttle body down low and at an angle.
I have thought about a custom intake manifold, but I am trying to keep the costs down. I figured that a remote booster will maybe cost a couple of hundred dollars and a custom intake $1000. |

mine is a TX gemini master cylinder with a remote VH44 booster from a valiant, that is tucked away under the right front guard just behind the head light, there is also a VH40 which is bigger if you cant find the VH44. |

Did you find an old gemini without vacuum assisted brakes and used that master cylinder. Or did you mount the normal master cylinder to the fire wall and make up a custom rod to connect to the brake pedal?
Cheers,

Custom made so clear brake booster, and clutch reservoir?
Do you think he would be keen in possibly making another for a slightly higher price than mates rates of course?

Correct!
The Plenum will be in a triangular for, so it clears the Booster and Master Cylinder, meaning the apex will be to the rear, utilising the S13 manifold, he will cut them to a suitable length and weld on the new custom plenum, the throttle bosy will be pressed hard to the left so when air enters the plenum it will run along the far edge of the chamber, no 1 cylinder will not get all the air and no4 wont starve,
im sure that he will have no probs in making another one,
he is in the process of making one for 40RST Yellow Stanza, and makes Fuel rails, maybe expensive though, but thats when you get fittings for it, Gene!!! |

I don't think the clearance problem is with the plenum. It appears to be with the intake runners (especially #2 & #4).
The #4 runner interfers with the booster and limits how far back the motor can be positioned in the engine bay, #2 runner comes very close to the master cylinder (requiring slight grinding of both to give only like 1mm clearance between them)
When will he be starting on the gemini SR manifold cos I would like to see it before I start making engine mounts etc. I am hopefully starting my install over xmas break.

I was just walking around a wrecking yard when I found a TX with one and no booster so I grabbed it, you could do the same with any of them like you say, you then have to shorten the shaft if you use a boost assisted one.
