Great post. Lots of helpful information for those of us new to F/I. One thing I was wondering if someone could touch on was pre-maintenance or things to have replaced on a car before going F/I. I bought my car used, and apparently just before all the maintenance issues need to be taken car of. My Z just broke the 70k mile mark and was wondering what major items need to be checked and or replaced if i plan to install a Vortech kit?

And if anyone has any info on the Vortech kit please let us know. Like things you would upgrade or replace on the kit. If i get this kit i had already planned on injectors, and oil pan spacer, and oil cooler. Just wondering if there is anything else on this kit i should think about getting.

 

Just wanted to subscribe so that I can refer to this thread more easily.

Nice writeup by the way

 

so, what does F/I mean?.... jk jk! lol sheesh damn noobs....very very good write up!!!

 

...

 

just bought my z last winter so i'm still somewhat of a noob in terms of FI. thanks for the detailed write up.

 

When are you going to update this?

 

What type of update are you looking for?

slide, do you know or have you received any information on the ATI Procharger that would answer any of these questions:

I already have a JWT stage 1 clutch with a nismo flywheel and a Motordyne spacer. A friend of mine is selling his Procharger kit with intercooler and spark plugs.

I'm in chicago so either GRD or SP would be doing the tuning. I'm looking to get 390-420 rwhp. What issues will I run into if I go with an piggy back (Utec or Cobb) vs. Pro48 (ProEFI) or Haltech stand alone. (I was thinking of going Haltech but I see a lot of FI Z's go with Utec's and I want to know the pros and cons of going piggy vs stand alone)

I will most likely be getting the AAM stage 1 fuel return system. Is that over kill for this kind of power? (I do not plan on building the motor)

Besides gauges and a tune, is there anything else I should be purchasing to do this right?

Thanks in advance if you can help with any of this!

 

The tuning aspect is all what your tuner of choice is most comfortable with.. If you're somewhat experienced in that department yourself a stand-alone would be ur best bet cuz you can make changes accordingly n datalog etc... not to mention the safety features it has.. (lot of FI Z's go wit piggybacks cuz its a lot cheaper as well). Not to say piggyback is bad but if you look into built high end cars all of em have a standalone system.. just ur safer bet when goin FI.
For ur kind of power i'd prolly say the fuel return system is a bit overkill but always plan for future changes you might make. We always say we'd be happy with a certain number but in the end almost 90% of the ppl want more power.
I'd also recommend cooling devices oil cooler n maybe a radiator upgrade n you'd prolly be good to go.



Looking forward to your "ditching the supercharger for a turbo" thread sometime soon

 

When you say the twins lack on high end, how bad are we talkin here? Is it a substantial amount?

 

Search the FI section. The best way to compare is to look at a dyno graph of a single and a twin. From there you can make your own assessment of "How Bad" it is.

 

/\/\/\
Talk about subjective....I don't think my twin setup lacks on the high-end...but most people say mine is a "big setup".
I bet in 3 years mine is considered a baby tt setup again.

Your an exception to the rule Tom!!!

 

Ha!!!
But you are correct Slide...many of the tt setups have too small of a exhaust housing which chokes down the power up top unless you are running some pretty agressive cams. The smaller exhaust housing is to help keep spool to a minimum...so where you gain in mid, you lose up top....give and take

Thanks for the quick reply! I spoke with Rick at SP and he told me that they perfer ProEFI and CJM fuel return sys.

I also asked for a rough estimate of just the sc install and he said roughly 1800 (20-30hrs) without tune so im going over other options now.

Another question i had is has anyone done this install themselves (sc or CJM fuel system) and where there any hicups along the way, would you strongly suggest having a shop do it vs. doing it yourself? And if I were to install it myself I want to make sure I would be able to drive over to a tuner with a base map of some sort or would I have to tow it?

 

1800 does sound like a lot.... shouldnt be that hard with tools at ur disposal n some time... Im not to sure on the return fuel system.. Like I said for ur goals i think thas overkill.. You might want to ask more of the advanced installers here on that..
As far as tune whatever engine management you do decide to go with i'd assume if you did the install urself your tuner could send u some sort of base map just to get to the shop... towing is also another option.

 

Does anyone else have some imput on this?? It is much appreciated if you do!

 

E46 M3 driver was talking some smack about the 350z the other day so I decided it's time to get some FI assitance. I've read up about this sts/rear mout kits and I'm pretty interested in one The simplicity of it is pure genuis imo. I'm not looking to break any records but would like to see off some faster cars on the road in general.

But I'm probably gonna get my tuner to help me fabricate a custom one in a similar fashion, as there are some details I'd like to do differently.

What I would like to find out is the following:

a) What size turbo's are most popular for this format?
b) Is there a schematic of the breather setup required for the oil return pump in order to avoid vacuum or other problems with the oil return?
c) What changes are required to the PCV system?

Anything else I should be aware of when going rear mount?


Thanks in advance.

Hope to be boosting soon.

 

Have you looked in Boosted Performance's kit? It looks nice and seems to make good power. Vids are online too.
