Project Karl, Turbo na post...
now, i know the mods of not fond on these posts, so lets try keep it in reason, so it dont get cloased.. im planing on turboing my na, and i wanna show what i do got, and u can hell me buy telling the stuff i dont have, and helping my along thru it.. im Very new to turbos so itz all learning to me, and whats the worse that can happen, i blow the motor.. i still have the Fb when that heppens lol.. soo here is what i do have
- S5 Turbo and manifold
- S4 T2 lim ported for a na to t2
- S4 T2 uim and TB
- S5 T2 ic
- S4 t2 BOV
- S4 T2 JDM down pipe
n332 ECU
2 550 CC injectors
and everything else you see in the pic
This is what i know i need
t2 fuel rails
engine wiring loom
2 550 injectors
AFM
T2 Ft cover

You'll need oil and coolant lines for the turbo, and an upgraded clutch as well.
May want an SAFC to controll the fuel a bit. I'm planning on running a little on the rich side for some extra protection. You may want to get all new gaskets to be on the safe side (I know I did).

You need a series four boost sensor. The non turbo one will NOT do.
I don't see why you need turboii fuel rails. Why?
Emissions wiring loom? If you do get a turboii Emissions wiring loom, then consider you NEED to take care of the two yellow plugs that do not go to the ECU. The ones called X-15 and X-16 in the series four fsm and called FEM-01 and FEM-02 in the later manuals. FEM meaning Front harness to Emissions harness. Wires need to be rearranged in those plugs.
Also something new to this discussion. The n/a and the turbo use different volume OMP's. Try to get the OMP with the front cover.
Here's an example of X-15. https://www.rx7club.com/forum/attach...hmentid=132792
The turboii wires are in the ( ). So let's say you have a turboii emissions harness and you have a wire that is BrR coming from the boost sensor. It is the output of the boost sensor. Now look, your now going to mate it with the standard non turbo half of the plug. Well, it's going to mate with a Black/White wire in the non turbo harness. Wanna know where that black/white wire is headed for? I'll tell you, its going to the ENGINE fuse (I think I've said Meter fuse in the past {wrong}. So now you have 12vdc coming from the Enigne fuse headed for the boost sensors output wire that usually outputs 1-3 vdc and splices off and heads for the ECU pin 2B (boost sensor input). None of that is good, so wiring should be changed for that pin.
See the other turbo wires,. the ones with the ( ) around them. Most are harmless except for the (BrB) wire that is a ground wire for all the sensors. That particular one on a turbo car is for the ground for the boost GAUGE. Well if you mate it with the WB wire on the nontubo car, then your putting a ground on a relay in the CPU. That relay is for the idiot lights.
I did most of the above from memory because there is no fsm available where I am right now.
Bottom line as far as I am concerned is..........use the non turbo harness. Lifer will be much easier in my humble opinion.
If someone finds me wrong about those colors and mating points, let me know.

You need TII throttle cable too. And also make sure that your TII UIM and **** have the brackets for the TII throttle cable still. There's 1 or 2 on there that hold it in place as it goes around the UIM.

damn man your further along with your setup than i am with mine, you already have your LIM ported to match etc. i'm still missing odd and end like a throttle cable and s5 TB (was going to do it on the targa but i have the 91 now so yeah . . . .) good luck

Honestly I can't see how this thread will ever work out. How many times did he have to re-re-re-rebuild his original engine?

In his defence though, they didnt actually blow, it was all coolant seal failure.
I wish him the best though, he's a very motivated little dude.

Seriously though, I would try and get a good NA rebuild running before trying turbos...
That's just asking for trouble!

I could ask YOU the same question![QUOTE]
Aaron used everything n/a except for the turbo and exhaut mani.
Entire long block, front cover, ecu EVERYTHING is still n/a.
