Well, finally got confirmation that the Greddy kit wont fit my RHD UK 350z

BUT, as some of you pointed out, the power enterprise kit will!
So it looks like I'll be ordering the kit as soon as funds allow!!
Been looking for as much info on this kit as possible, but I'm a bit unsure about the ECU situation on this kit. I'm not planning on cranking up the boost past the kits standard level (7psi??), so will i need a re-flash?? this could prove awkward from the UK.
Also, what are the MAF problems I'm reading about?? is this only for higher than standard boost levels?
Thanks for all your help, the UK is new to these cars!

 

The right and left manifolds are quite different to accomodate the steering shaft. It's too bad you can't go Greddy but I am hearing good things about PE. MAF problems seem to come into play above 8.5-9 PSI but it seems some cars are different depending on their MAF placement and set-up. Some have problems at 8PSI and others at 9+ PSI.

 

Do you know what the PE kit incudes to compensate the timing changes needed for addition of FI? as the Greddy kit does come with a piggy back unit.

 

It comes with nothing to adjust timing. IIRC on the fuel side of things there's a pump, injectors and FPR. PE say that's all that's required if you install the kit out of the box.

I'm in the same situation as you. Interested in FI but appear to be limited to the PE kit. I'm waiting to see what other ECU options appear before comitting to FI.

 

If you compare the two kits together, the quality of the kit you're getting on the PE is far superior than the Greddy. As for timing retard and fuel management, the kit as it is does not include any. According to PE, the kit out of the box is set at ~4 lbs of boost and good for 350 rwhp. No timing retard is needed and the larger injectors will more than compensate for the fuel needed. Needless to say, you'll be running pretty rich. However, if you decide to go to ~7.4 lbs boost (~400rwhp), you can send your ECU in to technosquare, and they will adjust the timing and fuel for you good for 8 lbs boost. Or, if you don't want to reflash your ecu, you can still opt for a piggyback to retard timing and manage fuel.

 

No timing control on Greddy unit either. Apparently they say their timing harness will not work with the e-manage and will fry the coils on the 350Z. Greddy says they will have a timing control unit out for the Z later this summer.

 

Just spoken with Technosquare about the reflash, thanks for the info guys.
Does the 350 rwhp relate to the use of the standard exhaust system?? I've got a nismo with kinetix cats on the way. Wonder what kind of power that will yield.
Will probably keep it at 4psi for a while, then upgrade the ecu as I go along.
Its looking better everyday this FI idea!!!!!!!!!!!
Will be the first turbo 350 in the country as well!

 

The only thing I dont like about the PE kit is the tubular SS Manifolds, rather than cast manifolds included in the Greddy kit. From my experience, tubular steel manifolds are prone to cracking with turbo applications.

 

350rwhp is with standard exhaust. If you're getting cats, you need to let technosquare know about it and they can reflash the ecu for the cats.

 

Well depending on what applications you've used them on 10:1 says that that manifold you had was junk, and was not well supported or had bad welds I have never seen an HKS or old Greddy manifold for that matter crack. Stainless will always be a better material to use for exhaust because of its high flowing characteristics, and low carbide precipitation. Reason being, more exhaust velocity is retained which promotes better scavenging at the collector. Which in turn increases the manifolds overrall efficiency.

 

"you can still opt for a piggyback to retard timing and manage fuel."

Would the Greddy emanage kit suffice for this purpose?

Also, would running the new injectors and fuel pump without an ECU reflash ruin the drivability of the car?? I'm not interested in high boost yet, but would like a car that retains its smooth driving and idling characteristics.

Thanks for your help, info in the UK doesnt exist, I'm relying on you guys!

 

IIRC the emanage can't alter timing either yet so it's just doing fuel.

Can't comment on driveability except to say I'd be a little surprised if it did. The only problem I can see is it'll probably run fairly rich which obviously would use extra fuel and if you need to do emissions tests it may cause a problem.
