For the ultimate power you want (especially to fully utilize power of setup) I don't think twin walbro's are gonna get you there. May need to add another walbro or an inline as well. Or twin Bosch's. (I have triple walbro's, and the third pump comes on with my setup.....so not gonna see big big numbers I don't think with just 2).

For the track.....I'd say a really good fuel sump setup (thats what we ran in a porsche GT3 cup fuel cell setup...5 total pumps lol)

just my $0.02

Aparently there is a taiwanese company that makes OEM brake systems for a **** load of auto makers. This company decided to come in to the aftermarket brake world. They founded Rotora. They also made all of StopTech's brake systems for some time as well.

If Greddy's are made by this taiwanese company, I feel even more confident. This taiwanese company aparently has been in this business for a long time making brake systems for lots of auto manufactures and that's the experience I would want going in to my brake system.

Stoptech, I guess around 05, stopped having their stuff manufactured by this taiwanese company and have no idea who makes them now. Don't get me wrong, I like Stoptech, scratch that, I love Stoptech. They were an incredible setup for the track and I barely got pedal fade when I ran them.

As stated before, I have not been to the track on the Greddy's. Once this motor is done we will have a lot of test and tune track days until is debut in to the Redline time attack series. I really do feel these Greddy (or whatever you want to call them) brakes will outperform the stoptechs when it comes to being on and off the pedal for long periods of time. The calipers are larger than Stoptechs (largest caliper for the 350Z from Stoptech is 6POT) which means more initial bite (I know some may say it also has to do with the size of each piston, well they are the same size as Stoptechs). The rotors are larger and meatier which means they should be able to disapate the heat better and be able to handle the track abuse better.

The only thing that I have felt different about the brakes is the biasing. I will check the bias next time at the track.

I am sure a lot of companies source the same parts from identical manufacturers....look at the number of coilover kits there are.

I love my stoptechs btw!

Yeah you were the blue Z that was doing about 450RWHP or something right? We were doing a test and tune on the supspension that weekend.

If that is you, I remember you were behind me for a lap and half or so but and I was trying to let you pass one the straights but I just come through the turns so fast it kept putting a gap back between us. I remember coming up to turn 7 and the car in front of me was going to let me pass so I let you pass both of us and I got stuck behind him till I exited 7. Then I remember coming up to "I think it was turn 9 or 10" and you spun out right?

I was only putting down 296rwhp compared to you being over 400rwhp it does go to show you that handling is key and why we chose to do this to the NISMO.

Again, if that was you I am thinking of. I know if was a blue Z this situation happened to just not sure if it was yours.

If so, way to push the car to the limit! Now you know the limit lol. It is something that MUST be done. I usually change my dampening to give me some understeer and I find my limit that way when I first get out. I know where my car is balanced but in situations like that day with a track temp of 155 degrees and hard apexes like Sebring, it gets a little rough.

I also had that red Z4 try and follow my line and spin out at turn 7 behind me. So funny... No one wrecked their car that weekend so that was good.

I didni't get any video that day so pretty cool you had that. Now if only it was't focused on that damn blue Z! lol, jk

The spin-out : 100% me . I kept getting braver and braver on that turn, till it bit me in the ***. Def a good learning experience.

I would of guessed you were more than 296 that day. Your car seemed like it had more. I was a bit higher than 450whp and gave the car no mercy. HI boost all day. Damn that ish was a blast and the car held up like a champ and then took on the 3 hour trip back home like it was nothing (with a few hard top speed runs *computer generated of course*)

Your gonna have your hands full with all that new found power. I had a blast at my power level and am still learning to use it at the track. i cant imagine what its gonna be like with the build im doing. Its nothing like yours though. I plan on keeping a relatively low wastegate setting to ease me into the new power and for track use. at my skill level now on the track crazy high hp wont do me any good. That whole day was a blast.

Do you always run with NASA or other clubs?

If they are our bottle neck like we originally figured they would be, we will get another pair from Greddy, send them off to have larger compressor and turbine wheels installed and put them on.

Can't believe you don't like the colors and wrap!

By the way, I added the pictures of the sleeved block from Darton.

this is the part that doesnt excite me as much for the kind of money and goal for the build, since its still a bolt on in essence and not a custom build with custom piping and sick welds... you could ahve used greddy components all the way still...and achive a larger turbo.... but oh well.


it probably looks better in person cause the pics sux a bit. Green is not an easy color, i just dont liek too much the tone used..but again thats besides the point.
I think you are worrying too much about the spool time too much already with 3.7L of displacement already, you could have jsut gotten better heads and rev higher(9k) anyways which would have been better for a track car probably...4.2L is nice, but with such small turbos it kinda defeats the purpuse...some real loopy (280ş+) cams might help
