Mighty Car Mods Builds a RB26 Powered 240Z

Our Nissan FairladyZ S30 (240Z) has arrived from Japan but not everything is as it seems with our classic JDM coupe....

Turbolag : RB26DETT

This is some old information. Will clean it up later. Just moving it from an even older site. 

The perception of turbo lag as it relates to RB26 powered vehicles. The dyno charts shown below are in no means scientific. They are done on different days, different cars, different setups. What we are looking at is overall ideas.

On this setup lets look at some horsepower levels and corresponding rpms. I want to start most at around 3000 rpms as thats where we start most of our Dynapack runs.
Looking at the blue stock line on these runs 8 psi on stock turbos, stock engine
3000 rpms 80 whp
3500 rpms 110 whp
4000 rpms 150 whp
4500 rpms 180 whp
5000 rpms 200 whp
5500 rpms 220 whp
6000 rpms 225 whp
6500 rpms 230 whp
7000 rpms 230 whp
7500 rpms 225 whp

This chart is a stock turbo car, with the boost cranked way up... 25 psi. Big dip is a boost cut.
3000 rpms 125 whp
3500 rpms 175 whp
4000 rpms 250 whp
4500 rpms 300 whp
5000 rpms 340 whp
5500 rpms 360 whp
6000 rpms 400 whp
6500 rpms 410 whp
7000 rpms 400 whp
7500 rpms 390 whp

Next is a N1 - AA403 car. On good fuel, otherwise fairly stock. Boost max of 23 psi. Tapering off in the upper rev range down to about 20 psi.
3000 rpms 155 whp
3500 rpms 200 whp
4000 rpms 260 whp
4500 rpms 320 whp
5000 rpms 390 whp
5500 rpms 420 whp
6000 rpms 430 whp
6500 rpms 450 whp
7000 rpms 420 whp
7500 rpms 405 whp

Same engine as above, but a swap over to "special Nismo turbos". Best I can tell by looking at charts and measuring them, is a HKS 2510 turbo equivalent.
3000 rpms 150 whp
3500 rpms 175 whp
4000 rpms 220 whp
4500 rpms 300 whp
5000 rpms 410 whp
5500 rpms 480 whp
6000 rpms 515 whp
6500 rpms 530 whp
7000 rpms 530 whp
7500 rpms 525 whp
Now the comparisions

Barely Legal R32 GT-R and Pao on Hoonigan Daily Transmission : #Bluecar On today's episode of Daily Transmission, Nads brings in Sean Morris who shows us how to legally import unique JDM cars into the states the right way.
Made a little bit of a mess
Our old friend, wait. He isn't that old. Or maybe he is. Anyway, John Naderi invited us out to a Hoonigan Daily Transmission.  Since we needed to bring something that we could "scumbag" in, we decided to bring the #bluecar.  Not driven much since R's Day, it got moved from Cypress, to the Hanger, to my house. Still had more than 1/2 a tank of race gas, and good tires.

The one thing I wanted to try was a center spin. Not much space at Hoonigan, with the car on 1 bar of boost, 275 RE71R all around, plus the grip there, I had them put some water down to try and help me out a bit.

The first time, I got it center spinning fairly decently, but ran out of room. The 2nd time was a bit more like a donut than a center spin, but during it, I managed to tap the dock with the exhaust. Results of that below.

May have tapped the ramp

Wore a little bit of RE71R off the #bluecar

The RE71R picked up a bit of rubber from Hoonigan
