Uh, why not? All 13B turbo manifolds use the same bolt pattern. I can't say that it won't interfere with the intake, but it will certainly bolt up if you enlongate the hole. There appears to be plenty of space to do this...

You mean what 2 turbos. He did say an FD manifold right? they are for twin turbos, and therefore he can use 2 turbos.

I really don't know much about the turbo system on an FD and really don't know the layout of the turbos on the manifold. So I guess I can't say much about it.

the FDs came n/a turbo or twin turbo...the turbo and twin turbo use the same manifold...just a t4 foot print for the turbo and a external wastegate....the original idea was to go twin turbo...but now im gona go with just a big single...setup if gona be a blow through on a 12a im rebuildin. im still debating intercoolin it or not...iv gota this weird idea in my head to have both....ill try to explain it..


ok there will be tubing from the turbo to the carb hat...entering on the right said (lookin from front of car) but on its way up it will T off and go to intercooler then out of intercooler and enter carb hat on the left...there would be valves to seperate when the intercooler was used or not....i would put on right after the T and right before the carb hat on the right(when closed make air go into T and into intercooler...then one IN the T and on the left of carb hat(when closed bypassing the intercooler. all this woudl be operated by a button ... does this make sense? also would it have a good purpose??? when bypassing the intercooler would reduce turbo lag...and when not would be producing more HP...right? tell me wut u thing. thanks

Why bypass the intercooler at all? Just use it all the time. I don't see why you can't or wouldn't. Most people just go from the turbo to the intercooler to the carb hat. I don't know why you are thinking about all this complicated bypassing stuff.

ive been looking for a bigger picture for some time now, but thats the best i can do. however, you can see that it comes off one flange, so one turbo can be fed off the manifold, or so it seems.


next obstical would be finding out if its a standard size flange, or something weird? you might be better off just getting a normal manifold.


edit: i just read your post. WHY would you go through all that trouble just to save a couple hundred rpm's in spool time? something like that would be totally custom, might leak, and probably wouldnt be worth the effort, much less effective. not to shut you down, but i dont see getting any real benifits out of that setup

see i was lookin for this kind of input...just wondering if its any good. it would be free for me....my bro can get me valves and do all the PCL programing to make them open/close at certain RPMs and would NOT leak....it was just an idea....but i might still do it just to do something different...... so did yall actually understand wut i was sayin....i reread it and said to myself "WUT THE F-CK" thanks

Not sure where you get your info from but it's pretty much dead wrong. FD's only came in twin-turbo form and and they use internal wastegates. You might as well forget about using a *stock* FD manifold on a 1st gen. An aftermarket single turbo manifold for an FD is a different story.

ok there will be tubing from the turbo to the carb hat...entering on the right said (lookin from front of car) but on its way up it will T off and go to intercooler then out of intercooler and enter carb hat on the left...there would be valves to seperate when the intercooler was used or not....i would put on right after the T and right before the carb hat on the right(when closed make air go into T and into intercooler...then one IN the T and on the left of carb hat(when closed bypassing the intercooler. all this woudl be operated by a button ... does this make sense? also would it have a good purpose??? when bypassing the intercooler would reduce turbo lag...and when not would be producing more HP...right? tell me wut u thing. thanks
That's about the dumbest idea I've heard.

Ive been thinking about a BOV bypass lately....... so you could rev at someone, and they would think youve got nothing, then you hit a switch, and blow them away.

FDs were only imported to the US from 1993 to 1995 (very rare to find 94s and 95s) and they were all twin turbo. So you can understand why everyone is giving you flak. If you still think your bro has a 96 N/A why don't you show proof?
