850CC Injectors
 

Anyone change out the injectors for larger ones FI guys, The Stillen Kit has 600CC's but I'm going up in HP and the 600CC's wont make it? Looking to close to 500WHP, I was looking at the DW 850CC's good? Any info on RC's maybe( Used those alot on my DSM's) Thans guys, BTW just ordered the Cog pulley upgrade, Thanx CLIFF !!

Also conside the Bosch EV 14 750cc injectors. I have been using these on all the VQ builds without any issues.

Thanx will do

That's what I'm using but in 650cc. Currently at 503rwhp at 8.5psi

Whats the duty cycle? I'm gonna be seeing 11-12 PSI.

I'll have to get back to you on that one. I know GTM uses DW600s on their 500hp builds but not sure what duty cycles they are seeing.

Really there are onlly using 600CC's maybe I dont need them then? maybe they could chime in or a guy with there kit?

I run the DW850cc. Plug n play

Dw > rc

When it comes to a supercharged car you will run out of fuel at lower WHP that a turbo car. This is because of the parasitic loss of the supercharger, takes up power to make power. Upgrade your injectors to be on the safe side fuel is something you dont want to play around with.

That is correct! A fuel pump voltage stabilizer might be a good idea as well.

Thanx guys, Just got he DW 800CC's,

We used these on a twin turbo 370z we did not to long ago. The car drove like factory after tuning, a very nice injector.

Ok so the 800CC' deal feel apart so I went with EV14(Boch) 850CC's.

Not a bad choice will give you some head room.

Thanx Squeeze, Side question, with the plugs out and most of them WHITE from running lean, What should I go with was looking for a heat range colder? But what brand? HKS, NGK? I have always used NGK's but also was in DSM's, This is my first Nissan build?

HKS 50003-M40HL M-Series Super Fire Racing Spark Plug Nissan Skyline GT-R

HKS 50003-M45HL M-Series Super Fire Racing Spark Plug Nissan 370Z

You can use either one of these.

We spent a lot of time finding a good plug. Its a very skinny plug. We actually found the GT-R plugs to work well in the 370z. The gap out of the box on those was .030". That's a DILKAR8A8 plug. You used to be able to only get them at the dealership but my main NGK supplier should be able to get them for me now so you shouldn't have too much issue tracking them down.

This is the plug we used with the twin scroll kit as well. No issues at all, and it is available through NGK.

Can you guys PM me with prices, and Squeeze thanx again man I will look at the HKS ones also, THAT GUY has been more than helpful, THANX

Great minds think alike :tup:
