Thread: Apexi SAFC & Neo Problem

The Blow Off Valve is Before the MAF so its not Being Metered i have the same set up in my 200sx and It works like a charm
about the MAF to the Inlet well thats About as imposible as it Gets unless i Knock out the firewall unfortunately it will not fit

once again i have it set up like this in my 200sx and its never given me an issue

about the MAF not being stock, I have them both as well as the ECU's original and Upgrade

Ive ran ALL original/stock (ECU & MAF) and its still goes Lean as soon as i hits boost

Ive ran it with the Z32 with the Nismotronic ECU and same as soon as i Hit Boost it goes Lean

oh yeah forgot to mention Ive also tried changing injectors I tried stock with stock and with upgrade
then tried some 65 Denso with a tune of course and nothing changes problem is identical no change at all

I am not a fan of this setup at all. The most common response that I hear when people run this setup is so that they can hear the BOV. Obviously it's not working for you so maybe it's time to try the STOCK way.



Did you ever consider (and grant it I don't know how much room you have to work with) running a RWD SR manifold - that way your turbo exhaust faces out the back and your turbo inlet faces forward giving you more room?


-----Bottom Line-----


I can only help you as much as you are willing to accept. I understand that you are faced with a space dilemma where the turbo and firewall meet. With the fabrication that you have done so far you should have no problem routing the piping correctly even if it is sticking straight out of the hood. Thou not as a permanent setup but something to get you running from 1k to 8k RPM.

You need to start at step 1 before jumping to step 10.

Sorry Guys didint mean to offend anyone i apologize.
I guess i will try that unfortunately its gana take a long while the RWD manifold is not an option
space is so limited i can barely squeeze my finger in between anything

A custom Manifold Must be fabricated to change the turbo from its current location
pipes cannot be ran elsewhere simply because they do not fit i have less than 1 inch clearance from the firewall
Top Mount will be the Only option but due to the space limitation its gana have to be made from scratch

will give an update when the NEW Manifold is Fabricated .....

this is the Customized Intake Manifold and the location of the MAF



and Here is the Turbo Location about 1' inch from the firewall

Yeah - your screwed on real-estate there. Good luck and those pics answer most of what I didn't know.

yeah i Know lol.. space is really bad,
already started fabricating the new manifold
trying to make it as less room consuming as possible
may not be as pretty as id like but will at least work to see if the positioning of the MAF is the issue

HOLD THE PRESS


Let's go further back, to step 0.


Have you tried running the engine with the maf connected to the intake manifold and turbo bypassed completely to see if you can get a full rev range and so forth.


Try this:
54C MAF
N14 ECU

Air Filter -> MAF -> Intake Manifold.

See how it runs like that and go form there.
