Looking for feedback from nitrous users that have sprayed a 100-125 shot on a stock f series motor. How did the stock motor handle the bigger shot? Any feedback on my current set up? I plan on spraying my f23a1 with a 100 shot initially and moving up to a 125 soon after.

~Zex dry kit
~Zex plugs
~Mallory Hyfire VI ignition (with push button timing retard and rpm activated window switch)
~tuned on a dyno with my SAFC II on 100 octane fuel
~ACT HDSS clutch

I've been spraying the car for two years on a 55 and 75 shot with this system minus the ignition upgrade and tuning with no problems. I'm looking forward to seeing what this motor will handle and appreciate any advice

 

i wouldnt try it without a direct port kit and a wideband o2.

I would think that a direct port kit wouldn't be necessary for this size shot. Obviosly it would be the best route to take but I'd think a wet or dry kit would suffice. hmmm

The wideband is a good idea and I plan on looking it

 

Am I the only one who thinks shooting a 100 dry is retarded? Go for something like a 50, 75 tops on dry. Why not just suck it up and go wet, you sound serious about nitrous. From what i remember when i was pondering nitrous on my f23 was use like a 75 wet tops, stock internals, anything else is more risk than it's worth. Btw how much did you pay total for your 5spd conversion?

Honestly, I'd rather push the envelope and blow the motor than keep running high 14s with a 75 shot . I know I've seen posts from people who have sprayed 100 shots on f series motors with dry kits. I've definately considered converting to wet before spring but not sure if I want to go through with that yet. I don't mean this as argumentative in any way but why are dry kits frowned upon with anything more than a 75 shot?

My swap was rather expensive because I bought a super low mileage tranny (30k) for close to $500 shipped and the clutch/flywheel were $550ish. I think total I spent around $1600 on parts with the shifter assemply new and ALL parts shipped as there were no 5-speed 6th gens at any local junk yards.

 

how many hours of labor did it take to do the tranny swap? and if you paid a shop to do it, how much did you pay (if you dont mind me asking)

 

just go wet and then blow your motor every run. it's what the pros do... you've got your sponsors like mcdonalds and wendy's to pay for all your crap. all they have to do is sell some french fries and you've got a new car. then you can have a nice out with your wife. she'd appreciate the business you do. french fries are really the key to good street racing. wendy's has fries and cheeseburgers to fund your hobbies. this is where all of the terms come from. sponsor is french fries and cheeseburgers. people race for money and sponsors. cops arrest people who want to make money. can't a brother get a break ?

 

hey lunarone, your just going all out tonight arent you? haha

 

You know, I've been kind of wondering the same thing. If the f-motor can stand over 300/300 at the wheels with just a head stud kit and good tuning, logically you should be able to run a massive shot with the same setup.

FWIW, my gut says that the 100 dry might be alright, but for the 125 you might want to look into direct port. I'd guess the head studs would be a good idea too since they are pretty cheap insurance. Definatly look into the wideband. I'd take alot of cues from the turbo guys, after all it's all just dynamic compression.

 

Why risk it? the possible cost to fix exceeds the cost to do it right

Risk what? A low mileage replacement f23 is under $300 so I'm not too concerned about the financial hit of replacing the motor.


Any feedback from those that have sprayed a 100+ shot on a stock f series? Tips? Advice? Etc?

 

just convert to wet and GET IT TUNED!! you should be ok..

also a compression test before is a good idea..
good luck

 

100-125 is considered a small shot? maybe for a domestic but thats almost more than what your f23 put down to the ground NA.

with that large of a shot from a single fogger you arent gonna get the proper atomization of the nitrous and fuel in each cyl, and with a dry kit, fuel is not mixed until the end of the intake manifold. the nitrous is gonna surge into the head and lean out the #1 cyl and CAN cause (not saying this will happen for sure) detonation. and being single cam you dont have the option fiddling around with cam timing like you wocan uld with a dohc where you could advance the exhaust side to help with things like puddling

Thanks man After talking to a couple people and getting these responses, I think it will be worth it to convert over to a wet kit.

 

i agree with hando a 100%......f23a's are dirt cheap, and if you do the labor yourself....with proper tune/wet kit, you might get away with it.......of course u might wand to head stud/sleeve the fawker for insurance purposes, but then you may as well build it from bottom up. My advice...you got a little money, have a second day driver, put a 125shot wet kit to work. Hell, who knows...properly tuned, even little rich, you might get away with it for a while....if motor goes, oh well, not like its k20 got blownup, u know....keep it stock....
btw...im on my third f23.....NA.....never shot....go figure

 

Bought a wet kit

as_fas_as_u: you should spray it this time around

 

lol....no doubt.....motor is going to blw anyways, again.......got pnp'd TB manifold head all port matched, milled head,5 angle valve job, cam, emanage to tune, not sure if a shot going to kill it it a lot faster...lol
