Whenever I build a motor, I'll throw in the Nismo oil pump with billet internals and rev the hell out of the thing. Until then, no way.

How did the tune go?

post the dyno results also if you can.

I keep hearing great things about Motion Lab.

Getting a late start. Fed Ex was way late on delivering the boost controller. I'll post up when we have some results :tup:

Well we ran into a fueling issue as we crossed into the 500whp range. The shop and Sasha seem to agree that the pump isn't getting enough voltage so a relay will probably need to be installed. I pulled the pump to make sure all the hoses were good just to rule that out and everything appears to be fine. The shop is pretty booked up until after the holidays so I'm not sure if I'll be able to get this straightened out until January.

These things happen. You'll forget all about when your up and running.

Yeah sounds like an easy fix. I'm just hoping they can squeeze me back in to finish the tune before the holidays.

Can you (or Sasha) expand on the issue/solution??

The stock wiring for the fuel pump uses thin wires. Apparently when you install these upgraded fuel pumps, they have trouble getting the voltage they need through that wiring. The solution is to run some thick gauge wiring straight from the battery through a relay and to the fuel pump basket. Some cars get lucky and get by with the stock wiring.

did this only cause issues above 500whp?
did you get a quote for the fuel pump relay parts n labor? are you going thru Motion Lab?

Yeah seems like it only started becoming an issue towards the end of tuning when they were making more power.

I'm going to get a quote from them this morning when they open up but it looks like a pretty easy DIY. I actually already picked up the parts for about $30. I'm not sure the shop will be able to fit me in so I'll be ready to do it myself if needed.

I am looking at making this relay setup a part of the standard package. The large 340lph that comes with the kit demands more power than the OEM wiring can handle (voltage drops due to small wire and length from OEM relay to fuel pump). With that upgrade the fueling system would never be an issue for those even considering pushing the limits of the stock block.

Guess I should add one during the winter downtime. Just to be on the safe side.

include it in mine when i order ;)

Yeah, mine too please :tiphat:

Looks like a mod for the spring

Just finished up installing the relay. Wasn't too bad really. Sasha pointed me to this DIY so I just followed that.

Cost me about $30 in parts. Car runs so I assume that means I did it right lol Hopefully motion lab can squeeze me in on Monday to finish up the tune.

Great build I love this kit!

Awesome kit and congrats on the DIY, can't wait to see your final dyno numbers. Really interested in seeing if the kit will fit a G too.

For those running this kit or other high HP builds. What clutch/fly-wheel combo is most recommended for reasonable daily driveability while still holding the torque?

SZ Clutch & Flywheel Kits for Z33 (07-08), Z34 & V36

Give Seb a call and see which one he recommends.

I'm running the Z1 6-puck w/ their lightweight flywheel and the ZSpeed CSC....has been holding the power awesomely and I don't have any problems daily driving it.

I am running Specialty Zs 6 puck clutch on the street (not a DD though) however I would have no issues DDing this clutch. I love it!

Thanks for the feedback. I'm definitely getting this kit as soon as I can get the dealer to cover my 6th gear syncro issue and give me a new tranny. DIYing it too but going to farm out clutch and radiator upgrade.

Hey Puchshaw, ever get the chance to hit the dyno to see how much you are making after replacing the wires?

Shop hasn't had any openings over the holiday. Hopefully I can get in there soon. I'll post results as soon as I get squared away :tup:

Scheduled to be back on the dyno on Tuesday. I'm going to try to run some data logs beforehand to make sure the fuel issue is fixed.

I just took the car out to data log a couple pulls to see if the fuel pump relay did the trick. I wound out 3rd and 4th gear and logged the A/F ratio for banks 1 and 2. Past 4150 rpm the A/F was pegged at 10. I'm guessing that's the limit of the sensors. So it appears to be running very rich now rather than leaning out. I assume we should be good to go now to finish up the tune on Tuesday.

I had to do the same with my car as well. I ran the wire and now the car has had no issues with keeping the AFRs in check.

Nice! That's good to hear.

The results are in! The fuel pump relay did the trick and A/F is holding rock solid now. The car was running pig rich when they put it back on the dyno so the wiring obviously made quite a difference. Final numbers: 487 whp and 465 lb ft at just over 10 psi tapering to ~7.5 psi. Dat torque. It's pretty damn cold out right now so traction is severely limited. Having said that, the car feels like an absolute monster. 3rd gear is insane :eek: The shop is going to send me an overlay of the baseline and final runs tomorrow but for now here's the final run. Baseline by itself is in the first post.

Looks good...but I think your tuner left a lot on the table after 5,500 RPM for some reason.I say this because the power starts to fall, and I have not seen that yet with any of these kits. What boost controller do you have? The timing must be pulled waaaaaay back in the high rpm range.

I'm just using a manual turbosmart boost controller. I know they went with a safe tune for everyday use but I can't say how conservative he was. Either way, this will keep me happy for a long while ;) Maybe when summer rolls around I'll look into pushing the kit a bit further if I feel the need.

Solid #s man but I agree from what iv seen this kit definitely has some more left in it up top! Awesome build. :tup:

Thank you sir :tup:

Oh, this will keep you happy for a long time. The torque is up there that's for sure, and it is what you will feel the most. Even in summer time, you will have a hard time keeping the wheel from spinning with that torque.

This turbo kit has infected me with the mod bug. Just snagged one of these:

It won't arrive for a couple months probably. That gives me time to decide on side skirts and a rear.

Yeah, that much power is enough to keep the monkey on your back satisfied for a good long time. I'm in the same ballpark hp-wise (but not torque-wise, nice job) and it still kinda scares me. I love it.

Honestly, I think above that power level is kind of a waste on street tires. 500whp, 600whp- they're all the same if you can't get any traction in the first three gears. :rofl2:

Haha exactly. I'm not sure what I would do with more power at this point. I have to baby the throttle as it is.

Yeah, I can't really give it any less throttle in first or second. What do I need more power for?

Thinking about these side blades:
