Turbo fitment problem

Post by **300max** » Tue Jul 13, 2004 7:18 am

I have a 1995 SE with ABS, ETD Manifold, and a t3/t4 50 trim turbo with a garret 4 bolt housing.

I test fitted the turbo today and found out that the turbine is less than an inch away from the master cylinder and that any downpipe I put on would hit the two metal lines running into the side of the master cylinder.

I've seen pics of other people Kat with the manifold and turbo I have and they are not having the fitment problem. Any help would be appreciated. Thanks

I have pics but I have no idea how to get them on here. The system keeps saying they are larger than 300X300 and can't be attached, even though I know i've seen pics on here larger than that.

Here is a picture of the problem

dont attach a file. Link the picture from a URL or host site. It should say IMG in the vB Code section.

It's hard to say without looking at how it lines up vertically. Its possible the right curved piece of piping may clear that.

The lines from the master cyclinder are directly in the center of the outlet for the downpipe. There isn't enough room for any pipe to fit. Would a different housing fit better?

Possibly. But likely not by much. You might have to look into modifying the brake lines. You can probably find a 90 degree elbow fitting that will fit in the Master Cylinder, then just run the line directly into this elbow. That might give you the clearance you need...

Also, switching to a 5 bolt housing will give you about another 1 1/4-1 1/5 inch of clearance on the bmc side.

thats strange... I have a lot of room at that area

here's mine:

No pictures with the downpipe on yet. Im too lazy to snap pictures cuz its too hot outside right now.but yea I dont have any clearance issue (downpipe wise)

Keep in mind that im suing T3 super 60, with .63 A/R turbine.

And here's mine as well, with a T4 compressor and T3 4-bolt turbine.

The outlet just BARELY clears the brake lines with less than 1" to spare. This is on an S14 with no abs.

Your problem is.............drumroll please...........

The ABS brake booster!!!!

It's about an inch thicker than the non-ABS booster, so it pushes the MC forward that same amount.

Switch to the a 5-speed booster from an S14, and you'll be good to go.

Trust me...automatic equipped S14s have the same thicker booster, and I had the same problem with my RevHard manifold and T3/T04E, 57 trim, 4-bolt turbine...except mine actually hit the MC.

Keep your master cylinder...it's 15/16", so it's better for upgraded brakes.

I got lucky and swapped with a local who's KA-T I built, and we used a bottom mounted T3...so he didn't have any clearance issues, and we swapped boosters.

BTW, S13 and S14 boosters are NOT interchangeable, FYI...

Why are so many people top-mounting turbos in the first place?Please don't say "accessibility." If you have to work on your turbo, and do stuff to it, there is something wrong with it, or you're taking it off to swap. That should be a once a year thing. Bottom mounts are better for weight distribution, and clearance. So why, guys? Why?

yup, damn abs booster.....

Manifolds just come like that...you cannot (easily) bottom mount a T3/T4 with RevHard, and it looks like the ETD will have the same issue.

The angle of the flange tilts the turbo inlet towards the motor when you flip it upside down, so inlet piping is a HUGE pain..it almost requires removing the power steering.

And then most T3/T4s will hit the motor mount anyway...

It's just a necessary evil unless you want to make your own manifold, something along the lines of "Phat-KAT".

Will the booster affect brake performance in some way? Also I'm going to do both change the booster and get the 5 bolt housing. So thanks to everybody who gave assistance.

Weight distribution? are you actually seriously saying that a top mount is worse for weight distribution than a bottom mount? Its such a marginal difference that its a non-issue. It means moving the center of gravity down such a miniscule amount that setting a big mac on the floorboard would do the same thing. Top mounts are the ****...thats all there is too it. Easy on the eyes, easy to run piping for, easy to work on.

this is how close mine is with the revhard and abs in a s13.

i have had this problem when i installed my 85/300 zx turbo on my 1993/ka24de. The solution is to install nissan pathfinder 1994/1995master cyl,the line was on the other side,but i had to add a connector to extend the lengh of the lines and run them by the fire wall away from the down pipe.don't attemp to bend the lines down as much that you can,they'l brake and leaks on the down pipe and fire is sure thing.......

I may have a solution for this buster problem. this manifold ,brake booter is a big prob!

Post by **sil80drifter** » Tue Jul 13, 2004 7:18 am

and you solution is... screw the brakes? use e-brake only? lolno seriously, what's ur idea?

Hey Orion,

When you swapped boosters did you need to change the brake lines going into the cylinder?

Post by **michael Walters** » Tue Jul 13, 2004 7:18 am

THE SOLUTION IS TO CHANGE THE MANIFOLD AND HAVE THE TURBO SIT CLOSER TO THE FRONT OF THE MOTO. TAKE A LOOK AT THE ONES BOOST BOY POSTED FOR THE CA18.

DOH! I thought the solution was to change the turbo to a smaller one!

Post by **sil80drifter** » Tue Jul 13, 2004 7:18 am

i thought the solution was to go N/A.

No...I just gently bent them to fit the new location, an inch rearward.

I kept the same master cylinder, you should too...it's bigger than the non-ABS MC.

ACTUALLY IF YOU TAKE THE MOTOR OUT YOU WILL HAVE NO CLEARANCE PROBLEMS WITH THE TURBO AND MASTER CYLINDER OKAIGHT PEACE OUT MY HOMIES
