New CUSTOM TURBO MANIFOLD 12a!!! :)
 

well, i'm having a custom turbo manifold made for my 12a blow thru setup. at the moment i have my own fabricated junk on there but it has too many exhaust leaks, so i found a professional who makes some of the nicest manifolds i've seen for our rotaries!!!! here's the 50% done pic! and the other pic is pretty much what it will look like (mine just has to go a little more forward to clear the racing beat holley intake). also, it's flanged for the stock s4 turbo i'm using. this way when i do a 60-1 hybrid rebuild, there will be no need to mess with another manifold and oil lines, etc... WOOHOOOOO!!!!! whatcha think?


p.s. "proxy error" in the title works!

My question is that a 13 RB mount or a 12 RB mount ?

would that clear the hood?

mine utilizes a 12a rb flange... hence my 12a turbo setup ;) he makes both tho. and yes, it will clear the hood with plenty of room.

Looks good! How much?

250.00! :D

Good deal! I should've just got one of those instead of searching for a Cartech mani.

Yea 250 isnt that bad does it come with the down pipe for the turbo or do you have to custom make that?

That looks really nice!!!! Be sure to let us know how the S4 turbo responds with that manifold.

fbII keep us updated on your progress! Nice one.

thats a nice piece zach!! renee is a good guy, we have been friends along time! like me he takes pride in his work, like most small shops do..

This is from Renee?? Good, he's local.

he just finished it today! heres the final product, i'm so fuggin stoked!!!! oh and i will have to make my own downpipe. s ok tho.

should spool hella faster, which will help alot when i get the hybrid! :D

How long are the runners from flange to flange?

Yup, Rene is a cool local from LA. he did my turbo header (using 89 TII turbo). This will allow me to use any intake (such as RB holley, IDA, sidedraft) for the FB

Try as I might, I can't get a new thread to post so I'm forced to semi-jack this one...

While sourcing parts to hop up my Daytona, I came across a number of VNTs and it got me to thinking these would work well on our 13Bs as well. Variable Nozzle Turbos (in this case, Garrett T25s) don't have wastegates - instead they have moving fins. When fully closed, it functions as a small turbo for spoolup. When opened, it's like a muck larger turbo for better breathing. Sort of like the FD 2 turbo system, but without all the complexity.

It also has the waterjacket I've written about before. Normally turbo cars have timers that keep the engine running after you've been out driving hard, because if you shut off the engine while the turbo is hot the oil could coke in the bearings and cause the turbo to seize. The Garret takes in engine coolant from the bottom that, when entering the hot housing, boils off, taking heat with it and bringing in more coolant through convection. No moving parts required, so you can just shut off the car and walk away without worrying about your turbo.

The thing is, these aren't widely used for rotaries. Either no one has tried it, or there's a good reason why. Am I overlooking something? I figure with no wastegate or timer required, but a virtual twin turbo in a smaller space, this would make for a good 13B conversion setup. Thoughts?

First Sweet looking manifold, length looks about right as long as it clears the hood.

And for our newest threadjacker: :D

Quit waffling Mantis and try it :p: (and then tell us how it worked) Oh and I love your new avatar :rlaugh:

kenn

Thanx - soon to be a T-shirt on Rotorhead.ca :)

yea, i think he used the pictures i sent him of my holley setup to make yours right?he said just recently he made one like this and it worked great. that looks identical to mine. :D kick ass!!!!!

actually, no. this is my second set. the first one didnt clear the RB holley. so I brought my the holley carb/manifold to ensure that it will clear it. I picked it up last saturday.

yea, that's the one. he said it was tested and worked great. (your second set i guess) wooooooot! so yes, mine is exactly the same as yours. YAY!

I don't get it, Why wouldn't it clear the hood? Isn't it just sticking out to the side?

yep, pretty much hahahaha

Hey I need a manifold for my RHD SA. Going to install a S5 TII in it.. Can he make one? Thanks

Those are some Nice looking manifolds..

Manntis - Because to rebuild one of those turbos would cost your left Nut.
I believe some of those had Ceramics too.

thanks! i'm so proud to be putting this on my engine. it changes everything lol! now i gotta clean up everything and show it off :D

According to VNT owners, the turbos outlast the engines...

That manifold kicks ass, if i had a 1st gen with teh 12a id get it

Manntis-the secret of your avatar is God is just jealous because he could not drive a Honda NSX.

how can we get in touch with this guy? I have been piecing everything for my turbo project aswell and I need the manifold made somewhere......

However it's be for a 1984 gsl-se but I'd need it to be able to clear the Lower intake manifold. I have and s4 turbo also.

ssautochrome has a new maniflold for the s4's with stock turbos..... its a tubuar manifold which I was thinking of buying and modding it.

Rene's SN is 61620B. Im sure he can make it since he has my first manifold as a template. As soon as Im done with the FB, the RX-3 is next but this time, it wil be a bigger unit and it will be a bridgeport. Anyone interested in a GSL-SE P-Port housings?

please dont go with ss auto junk. waste of your money. :(

Do you have a measurement of the length of the runners?

In Canada it's the Acura NSX - different emblem ;)

woooooooohooooooo its in
 

now back to the drawing board to design the oil return/drain

I still have the fittngs if you need it. I won't be here this weekend though.

hey, wacky, that turbo looks familiar.... where did you get it? whats the serial # on that baby?

Yea how can I get ahold of this Rene Im looking for somebody in Florida to build 1 for my 12A project...Any ph #'s..............?

I got it from an asian sweat shop. ;)

Thanx wacky......Ill be given em a call...........

i hope mine comes in tomorrow! AHHHH, then i'll be ready to tune! YIPEEE!

Oil Drain: Oil Pan Vs Front Cover
 

Out of curiosity, I installed an old 4port 13-B oil pan to the engine mock-up (no front cover) and added used oil until the oil level is in the dipstick's full mark. I observe that welding a bung or a drain in the pan is not a good idea as the drain is almost submerged in oil which can cause slow drainage or a bottle neck. In addition, during hard left cornering, it will be worse. Based on the above, I feel that the drain should go in the front cover.

FYI on oil level: At full mark, the oil level is less than 2 inches below the oil pan flange.

this is why i drilled and tapped in the front cover right under the omp. helllll yes.

sweeeet, mine came in today! YIPEEEE!!!! maybe i can get my return line done today.

Yea I kinda like that one actually I was looking at it thinking it would be in the way but no it looks more thike it would be out of the way rather than genurating lots of heat directly next to the engine ..... hummm that is actually a really good idea. man ask him how much to ship to 83642.

Thanks

WOOHOO!!! here's a couple pics of it on. still gotta fab up a downpipe and finish the oil retrun line. i'm f-in stoked!!!!! amazing welds, just a damn great piece overall and puts the turbo right up there. peerrfecct. now i gotta polish the damn housing when i do the swap in to the other car. muhuhahaaaaaa!


oh and sorry for the shotty pics, my digi-cam is old and sux :p:
