Hello,

Just wanted to report back.

After browsing the market I found that most Japanese FPR seem to be copies (unless you buy directly from manufacturer)

Telling fake and real parts apart seems also to be no easy task.

I also found that the standard Tomei/Sards are not good for high HP or high volume fuel pumps.

All things considered I have singled out this one (from th US)

http://aeromotiveinc.com/products-page/regulators/efi-regulators/13101-a1000-injected-bypass-regulator/

It looks well build, professional, and has proper fittings (so piece of mind)

The price is about 20-30% more than a genuine Tomei ..

Cheers ... :)

I'm using a SARD RJ (bigger one) with two 044's feeding it. Not a problem. Also have a fuel pressure gauge and it follows the boost needle as it should!

Yes, the bigger Sard is actually OK!

(If genuine)

How much did you pay for it??

yeah sard RJ are about $300 and are a good reg. even the small sard ones are fine for probably 90% of applications, you just have to buy a genuine one which is nigh on impossible on ebay. from memory retail japanese price is about $180 for a sard reg, and about $60 for the gauge and maybe $20 for the nissan adapter. I see them on ebay with all that for $60... now you tell me if you think it's real... on top of that i'm fairly sure the genuine sard fuel pres gauges aren't liquid filled, all the ebay ones look like they are to me.

Hello,

Yes, that's the issue ... how to isolate a non fake one...

Even on YAHOO! Japan plenty of fake Tomeis!

Can you answer the following question.

I'm unsure as to how to route the fuel lines via the FPR.

Should I:

1. Coming from the pump go first into -> FPR and then into the Fuel rail (need a 2 port FPR then)

or

2. Coming from the pump go first into -> Fuel Rail and then (from the other end of the rail) into the FPR?

Or doesn't it matter, since the pressure should be the same (along the line) as long as the regulator is attached anywhere on the pressue side?

Also:

Shinuku?

I lived there for a year!

FPR has to be on the return side unless your running a returnless system in which case you can T off the feed line and have the reg going directly back to the fuel tank. but for a basic setup leave it as per standard

Thanks for the help ..

I asked the FPR-Manufacturer the same question (2 days ago) and here's their answer

(I will now go for their product, since it is genuine and the support is also there :)

:

Andrew,

The optimum plumbing for dynamic fuel delivery to the injector will provide the line from the pump be connected to the fuel rail first, on one end, and then out the other end into the regulator. If more than one fuel rail is used, a Y-Block should be installed to split the supply from the pump into both rails, then each is connected to the regulator on the other end (two inlet ports).

Hope that helps, let us know if you need further assistance and thanks for choosing Aeromotive!

      From Japan and back to Europe, my sh*tbox R34 GTT

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.

      I assume clearances were all a-okay?
