Asking for non-sequential help please
 

First I'd like to say my car is running great

I have a pettit ecu and pettit streetported motor

I'm not totally sure that everything for the non sequential mod was done correctly on my car.

I'd like it if you guys can help me out and keep checking this thread so I can get everything hooked up right.

Currently I have an intake and full exhaust and my boost gets to 12psi arond 4k rpms and stays there till redline so everything seems to be running great.

I'm just a little paranoid so can we please go through every single thing that needs to be hooked up and also post pictures or very clear diagrams please. I'm sick of looking though all the different sites and diagrams. I want just one good one. I will also take pictures of my engine to show you how it's setup now.

My first question is about the omp. Is there a specific way this has to be hooked up?

If you know please contribute. thanks everyone!!

If you mean the vaccuum lines, then they're supposed to be T-ed together and go to the nipple on the plastic intake before the turbo. They need a constant vaccuum source.

I will mention once again that I already know what the sites say and everything. I don't understand it that's why I'm asking.

What vacuum lines? What 2 are teed together??
plastic intake before the turbo? intake pipes? crossover pipe? WTF?
Do you have a picture or a diagram please?

there are 2 nipples under the uim, just towards the drivers side of the secondary fuel rail. t them together and connect to the small nipple on the front black plastic,turbo intake elbow. i don't have any pics, but i believe there are some in the the rikki non seq thread, which i had to read about 10x to get right:biggrin: hope this helps-garrett

Ok, I take it from whats been said that you've done the poormans non-seq and not the full non-seq?

If thats the case, follow dontbearikkis instructions. No matter how wrong you think they are, they're right. As turbogarret said, it took me about two days of reading and thinking before it finally clicked. And then I went, OOOHHHHHHH!

As far as I know, the poormans non-seq doesn't touch the OMP, so could you further explain that one?

My site use to have that info but the web guy just rebooted it and lost some stuff.

see if someone has a link or search I know I did diagrams and pics on this forum.

Ryan I just went looking for your site and saw it changed, then I saw you sold your car!!??! When's this turbo RX-8 thing happening?

What do you mean by the poormans method. I have blockoff plates on the motor and I took out all of the sequential shit except for the solenoids because I need them for my pettit ecu not to throw codes.

I'm going to get a diagram and point out everything that I have done for sure and everything that I don't understand.

I don't want this to turn into a 3 page thread and still not have any answers or anything helpful so please make the replies detailed and full of important facts accompanied by diagrams. Picky huh?

lets take a look at this and help out folks.

Look at my questions on the first one and you can edit the second one.

okay I just found the 2 hoses from the omp

Can I use normal vacuum tube for these?

They are going somewhere on top of the motor it looks like I'm gonna tear it all down.

Okay so I T those together and what plastic intake niple do they go on I dont get it

Chow

what the hell is the charcoal canister and where should it be I don't see it anywhere.

after the catch tank a line goes from there to a metal hose near the fuel lines

Also, what's involved in full non sequential
I have block off plates are there just 5 possible plates? THat's all I have.

?????????????????????????????????????????????????? ??????????????????????

Help ?

do i have to take pics and ask if its correct or something?

for the omp vac lines, t them and run it like the light blue line on the drawing, to the nipple on the front turbo intake, so it gets vacuum. yes use any vacuum lines for this. if possible get a brass t, but the smallest i could find was 1/4"which works ok. the charcoal can is located near the fuel tank, i just disconnected mine. full non seq involves taking off the manifold and grinding out the door and sequential bs. as far as the yellowish line that comes off the y pipe and goes nowhere on the drawing, i just have it capped off.-garrett

oh, don't forget about the fuel pressure regulator which is probably the most important one and for some reason is not shown on those drawings. nipple on secondary fuel rail(down low, towards firewall) to nipple on outside of lim facing firewall at an angle. just go through that rikki non seq thread and you'll be fine.

I'll edit the current diagram so that it's more easily usable. Post a pic here when I'm done and on the other main non seq thread

Snook....

Im curious, what was with the lecture just last week about how non-sequential sucks and that its "Sequential for life". You were the main reason I passed up the non-sequential turbos that were sale (which I'm thankful cause i found a set of very low mileage sequentail).

Answering your Q's from the dia top down.

-That hose is for the PCV, 95's didn't have it, so I don't know if you should remove it.

-Yes you can pull them out or weld them or cut them or ...

-You don't need to "wire the OMP" the only thing you need to do has been stated 4 or 5 times in this thread already so I don't need to say you T the two lines from each nozzle that is on the block and run a line down to the turbo inlet elbow...and you don't need that metal mess of pipes.

-answered above

-cap that line "WTF" does this line go.

opinions one what your trying to find????

I saw in another thread Jimlab said he was getting full boost non-seq by 2800rpms or something crazy like that...with your mods, I don't think you'll be doing that.

However I have full non-seq with all emissions and I get 10psi by 4k, so I would think with a full exhaust you should spool the twins quicker...maybe the street-port effects the spool up in a bad way???

Oh yeah - get an efini y and a SMIC and you'll see a difference.

I think I finally got it guys.

dubulup thanks for clearing some things up

zerobanger im glad you found some turbos finally instead of reusing yours. Non sequential does suck compared to sequential. The only thing I like about it is that i can take everything turbo related off of the motor in 5 minutes and put it back easily. Theres hardly anything to it so if you are having a problem its easy to find. We were in a rush when we put in my motor and I didn't have time to screw around with all the bullshit so I just went non sequential right there. So i'm talking from experience I've had both at around 13psi and non sequential is very laggy even though I have a midpipe. You made the right choice and don't worry about me I'm selling my car. I hope you enjoy your car when you get it back and break that sucker in good!
