Project Nismo Turbo build

That is pretty wild that the pump is already bad. I have not seen that from the 450s. The 255s didn't have the best reputation.. but the 450s, so far from what I have seen, have been very reliable. I have tried to deal with Walbros warranty before and discovered that they do not really honor it.

The relay kit will be a good idea. The stock wiring gets incredible hot to the touch running that pump... I know because I did it for a long time (made 670+ whp and ran 11.2s with a 450 on stock wiring). Its not ideal and it definitely needs to be upgraded but it would be odd for the stock wiring to prevent you from getting out of the driveway the first time. If you tried connecting the pump directly and it doesnt spin, I think you just got a dud.

That sucks to hear about their warranty. I work in the dealership service industry and warranty is never an issue. Even with Autozone, Napa, etc their warranties usually cover most parts. I'm in the process of upgrading my fuel pump and injectors and will keep this in mind.

I can make this kit myself. We own an auto parts store and relays and wiring are no problem. lol

that wiring kit looks like it could be made pretty easily TBH

From where the fuel pump is located, i don't think so at least nothing i would depend on for something so critical that can damage my engine.

It's a straight shot down the passenger side through the firewall with a already nicely placed oversized grommet opening right near the battery. If you loom it right along the existing cables you won't even notice there.

I managed to feed 1/0 cable through there for the stereo so there's plenty of room.

Made our first road test Sunday morning and

was it fun! 600+ HP on these cars = wild street fun for sure.

I dropped it off yesterday at the race shop for corner weight balancing and alignment. Hopefully I will have it back early this week and make it to the track for some testing.

I installed adjustable camber arms, toe arms, end links, upper control arms and coil overs. So everything is out of wack

I think he might have meant fuel wise. Was it just a bad fuel pump?

Oh LOL.
Yep, swapped the pump and she fired right up.

So....Went pick up the car from the race shop yesterday and I need to add more parts to the list!

We could only achieve -1.9 degree of camber on the rears due to the spring bucket adjustment only being an eccentric bolt. So, I will need mid- links or a true type coil over set up in the future to reach the 0 degree camber set up that I am looking for.

Also, I tried a full power run on the street and the clutch will not hold a high rev shift. I already knew that I would have to replace it. But now, I don't think I can pull any good 1/4 mile runs at all with this clutch. (might go easy shift it at this import event next month just to go)

Bad news, I have to pay off this trailer and some parts before I can move on to these new developments. SO.... I will have to drive it "as is" for a few months

and be satisfied.

And you want to fix your fuel pump wiring asap. Nobody wants sudden lean AFR'S at a 14 psi pull...

Doesnt the spring bucket adjust toe? Do you have camber arms or have spc toe bolts those should get you where you want to be.

Yes but I can only get -1.9 camber while maintaining zero toe due to running out of toe adjustment on the spring bucket
