TD05H Manifold?
TD05H Manifold?
I have a '91 Eclipse GS-T and was wondering if I could just get a manifold for my '86 RX-7 NA to put the stock 14B (TD05H Housing) onto it. Can anyone send me a link? Has it been done? I know that turbo is capable of 18 pounds of boost safely on the DSM, how about the RX-7?
1) You have no clue what turbocharging is all about.  Go read Maximum Boost by Corky Bell first.
2) You're going to blow your NA up.  You'll need to spend close to $1,000 just to make sure it can handle the boost, or blow the rest of the NA drivetrain up due to the increase of power.
3) The turbo is too small for a 13B.

The compression on the N/A is too high to just slap on a turbo and expect a useable car. Also, after about 230hp, the stock drivetrain gets real easy to break...and that was new. Talk to Aaron Cake here on the forum. He just finished puttin a turbo on his n/a. Lots of work and custom fabricating stuff for the setup to even run. Good luck, and save your pennies for a TII...

But there are many other reasons why this is a waste of time. For starters, that turbo’s smaller than the one off a TII, which doesn’t require a custom manifold. Then there’s fuel requirements, drivetrain strength, etc, etc...

Instead of ******* criticizing me why not make a useful comment like tell me what I said that's so wrong. Now tell me why it's too small for a 13B, because of the high revs? La de da, it'll still provide power through 2-4k, and that's better that nothing. Once again, don't be a ******* dick to someone you don't know, espcially when you're not even going to help.

1) What the stock compression is one your NA?
It's 9.4:1.  Go read up on compression ratios versus boost - this doesn't matter for piston or rotary.  Read the ******' book.
2) Do you have any clue on how much boost you can run with that compression ratio on pump gas?
You'll be lucky if you can run 15psi.  No way the stock ECU can do this, period.  15psi with a stand-alone EMS with very conservative tuning.  Right there is a $1,000 purchase.  You'd be lucky you could run 10psi with the stock ECU - natch, your 18psi statement don't mean JACK, unless you feel like blowing engines up.
3) The last time I checked, the stock NA doesn't come with an intercooler - DUH - you need to run an IC anything above 7psi-10psi.  It's in the ******' book.  This means you want to run higher boost (i.e. 18psi) you need a front mount intercooler.  Oops, another $1,000, unless you're going try and get cheap and run some second hand OEM IC from some other turbo engine.
4) You need to beef up the stock fuel system.  I doubt your stock fuel injectors are adequate, and surely the stock NA fuel pump is inadequate.  Fuel pump (Walbro 255lph) is at least another $100.  Bigger fuel injectors is more money.  A'PEXi S-AFC is another $300.
Just right there, you're looking at easily $2,000 worth of mods just to get your stupid project rolling out your driveway.  Ideally, you're looking at a minimum $3,000 bunch of parts and over 100 hours of labor.  It's a ****** waste of time for maybe 300hp maximum due to the sheer limitations of the engine and pump gas - it's in the ******' book.  Going beyond that take more money, more labor, race gas - you willing to do that?
I think not.  Have a nice day...go back to high school.

Now that was more helpful. First off, thanks, I didn't know the compression ratio off hand. Second, I asked how much boost you guys thought I could run, thanks for answering, although you didn't have to be a ***** about it. Third, no **** I need an intercooler, I wouldn't run a turbo without one. That's just common sense, did I ever mention not using an intercooler? Fourth, I'm aware of the fact that I'd need to beef up the fuel system, again, not what I was asking. And finally, I'm out of highschool for the summer

As for it not being worth it, I don't know about that, turbocharging is always where I go first for extra power. I know the 14B TD05H isn't the greatest, but it's what I have and it's free. Not to mention the fact that by merely replacing the compressor wheel it can be converted to a Big/16G and a 20G. I believe, though I don't know these cars very well, a 20G would be worth the hassle of the manifold, fuel system (I'd use an S-AFC anyway), and the intercooler. Any other brilliant comments, RETed?
Zenki turbo and manifold are practically "free" if you look for them.  You're better off selling that DSM turbo to a DSM owner who needs one.  Even the Zenki turbo and manifold off a Turbo II is an easier conversion that your DSM turbo.  Aaron Cake has write-ups on the stickys at the top of the list - go read them if you haven't already.

from what I can see everyone is trying to discourage you, it's well meant advice since turbocharging the N/A rotary is no easy task, but anything worth doing is never easy.
I just bought a tdo5h 14b w/ plans to turbo my engine, since I'm planning on swapping my stock 13b ( needs oil seals ) for a 13b-rew, I thought I would experiment on my ready to go 13b, who knows, maybe I'll just leave it as is.
Good Luck

you do know this was from 2002.....
the tdo5h 14B, even the 14G is way too small for a rotary engine. The turbo is smaller then the stock turbo for the FC.
With the size of the turbine on the tdo5h the turbo is going to run out of breath at 3-4krpm, the stock turbo for the fc runs out at 4-5krpm, after that the boost falls.

Nice zombie thread.
You'd probably make less peak HP with an itty-bitty 4 cyl. turbo than running NA. You'll get a brief wave of torque, then the tiny turbine / turbine housing will choke the life out of the engine. The torque curve will look like a parabola.
