is a tune necessary with nitrous?
Depends on alot of things.(What mods you have, what shot you plan on running) Generally, if your engine is running correctly, then with the right jetting it will run fine on spray as well.

^ Should be obvious, but it depends on whether or not you can drive.

I have a question. I have a Y7 with a crappy B8 intake manifold. Would a small 50 shot (dry) hurt anything? I haven't installed it yet, but I will be running a P28 and the corresponding injectors (240cc or whatever they are in the Z6).

Compression is good, and I'd retard timing. If you couldn't tell, it's my first time spraying, so I'm being overly cautious.

I just put together a 10:5:1 d15b2 with d16a6 head. Crower rods, ross pistons, rings gapped for big nitrous... Im going to use 150shot on it.

D16y8 with I/H/E, VAFC2 untuned looking to see what you guys think, if I should run the 75 shot or I should just stay with the 55 shot and do a Zex (or Crower) cam, springs, and retainers? www.sohchonda.com got me all giddy when they wrote an article on "13 seconds under 3,000" with basically a 75 shot and some weight reduction....possible? Not sure if any of you guys read it, but it was definetly interesting. To me, nitrous is the most affordable way to 13 seconds, but they make it seem to easy.

I run oem type R plugs on an 85 shot. I've had them last 2 bottles
You should be using 1 or 2 heat ranges colder with an 85 shot. I used to be running a 90 shot through a 1.5l in my 94 DX hatch and with 1 heat range colder plugs I was going though a bottle a week and never had plug issues.

You should NOT run OEM heat range plugs on the bottle. Chances are the electrodes will melt and those bits of melted metal will start banging around inside your combustion chamber.

TurboedEK, if you are serious about a 175 shot on stock internals...I hope you're already looking for a new one.

TurboedEK just wondering what motor you play on running a 175 shot of Nitrous on? And I'm also running the Zex plugs on my y8 with a 75 Dry shot, seem to work very nice.

I finally settled on these plans :

- d16a6 block, ported head, stock z6 gasket, ARP studs
- Eagle/TT rods, Arias pistons (the highest compression ratio available)
- blockposts + stock sleeves
- nice header (bisi or the like), 2,5" exhaust
- big cam (300+ adv duration, 430+ lift, LSA 11,2°)
- Webcams CG-601 camgear
- bored out TWM intake manifold with twin Mikuni PHH40 sidedrafts
- 45mm velocity stacks with socks
- small MoCal oil cooler
- crank scraper (if I can find one ! Ichihara-Johnson <sp?> seem to have vanished from the net...)
- ditch the vac advance and go for an MSD 8091 + Blaster coil with a CRX Si dizzy
- 250 shot direct port with progressive controller

I already got the head, carbs + mani, camgear and cam.
And a 50 dry shot that's useless to me now. :(

I'm going to put that stuff on for now with a milder cam and the MSD setup, and run a 75 shot DP on the stock block.

Sounds good, or have I missed something ?
