I'm running a 75 dry shot on stock fuel sytem just get one step colder plugs and run 101octane or higher and you'll be fine. oh i would recommend a window switch cuz its a good safety feture. I've put 2 bottles through my engine in 2 weeks and its running like a champ. But i think alot of ppl on here will recomend it.

it could probably be done. A 190 walbro cost less than $100, and the install looks like it can be done in about half an hour..better safe than sorry

For you running the dry setup, how are you providing the fuel enrichment when the nitrous activates? spraying the maf?

by **kenlrw39** » Fri Aug 07, 2009 9:43 pm

Mines is taped into the airbox spraying about 3-4in from the maf

the system i'm looking at has a selonoid for the fuel as well as the nitrous.

also. wouldn't you want to spray the nitrous between the mass airflow sensor and the throttle? and not in front of the maf.

by **kenlrw39** » Fri Aug 07, 2009 10:06 pm

That would be a wet sytem your looking at and yes you would wanna spray it after the maf because that extra selonoid add the fuel but for a dry system you only have a nitrous selonoid so you relly on your maf to increase fuel.

And I'll drop this now cause it took me forever to find if your gonna run a window switch on a gen 1 the rpm wire is the orange and black wire on the ecu i believe in the second connector from the top it took me 3 days to track that info down.
