Just purchased a n20 kit if eBay just wondering if anyones fitted one to a let??
What jets are best (safest) to use on what I believe to be standard internals

id look at a progressive controller too

Been looking at pro controllers.... There fookin right expensive!
100 N20 50 fuel?? Please explain..

just to clarify is that the one that taps onto the fuel rail bleed valve?
mike means 100bhp of n2o, 50 bhp of fuel, iirc.
you wont get a better delivery with anything but a controller, it puts less strain on the motor.

I get what you mean now cheers!
The kit I've got comes with 25 50 and 75 bhp jets but I think il be trying the 50bhp ones to start with untill I can afford a decent controller.
Whatever power shot you want to run, half it an thats the fuel jet size.
good man, and remember, get it set up on a RR. make sure shes not lean, or pistons will turn into round melted puddles of poo.
Retard the timing by 2degree aswell.
100 N2O 50 Fuel
Has he even said what kit he has ?
Is it a NOS, WON, NX kit ? from what I remember only WON use jet numbers like you have mentioned.
2:1 ratio is ok for a 3 bar setup, going to be quite rich on boost though, its safe but is unlikely to give maximum gains.
If your not running them already fit some NGK BCR8ES spark plugs gapped to 0.6mm.
Don't worry about pulling any timing out, you can't anyway but you don't need to even if you could.
Get a pressure gauge for the bottle, if you jet it on a cold day and the bottle pressure is low then on a warmer day the pressure is high the engine could lean out but it won't on 100/50 jets.
My advice would be to get a bottle heater and a gauge, keeps everything consistant and means you get the most out of the setup.
Not a let but I fitted a kit to a Volvo 340 the other month, its running a F7P Clio engine, thats on 50 shot but were on 100/40 jetting and its spot on.

The kit iv got is a zex wet kit the bottle holds 10lbs of gas but he didn't state the bottle size..
Iv got to pick it up on Friday so il post a few pics up!
I need the valve for the fuel take off where's the beat place to get one??
Take the fuel from the rail, just remove the centre of the valve and get a adaptor from that to the fuel solenoid.

Shrader valve! Check... Nice on lads il keep you updated..
I'm getting a tx autosport 3" top hat anyone ever tapped into there or is there a better place to tap into??
Dont put the jet facing directly at the throttle flap, ive heard a couple of horror stories of poeple doing it an the throttle flap freezing in position when its at WOT.

Either in the intake hose before the top hat or in the hat bouncing off the side somewhere.
Personally I'd have it on the pipe going in allowing it some time to mix
aye, id put itin the top hat but furthest away from the tb. :)

Makes sense I think il put it just where the top hat meets the boost pipe.
I think I'm gonna need a few hints and tips off you lot when I install it tbf itl not be for a while yet... But all help is welcome
buy this:
http://www.amazon.co.uk/Nitrous-Oxide-Performance-Manual-Speedpro/dp/1904788890
and read it. THE best book available on the subject.
or ring up Trevor and order it from them

Sorry for going off topic, but i was thinking about fitting nitrous oxide to my c20Xe on carbs it's a fairly high spec engine, first question is, is it possible to do so 2. what should i look for (list if you could)3. what sort of hp jets would be "safe" . I was going to look for a second hand kit on eBay etc, having no experience of it i haven't a clue what to look for and what to buy and not to buy.
see my post of the book. thats the best help, basic list:
wet kit
various jets
bottle warmer
RR time for setup.

One thing I'm after is a bottle bracket the kit Iv brought has everything I need but one of the brackets is broken apparently.
Untill I pick it up Friday I cnt say if it's fixabe or not, but where do I get one from.... Iv tried searching google but I cnt find anything?? I think I could fabricate one buy I'd need bottle straps from somewhere?

Thumbs up!! +1 for the info! Iv been searching everywhere.

Braked rollers are a no no, personally I wouldn't trust anymore than what the plugs look like which is easy enough to do on the road.
If you need a kit, PM me, I have a spare Wizards Of Nos kit here and can supply any extras you may want with that.
For Carbs you will need a direct port kit ( a injector for each trumpet basically )
am i right in thinking sheileded nose plugs are needed?
Shielded nose ?
non protruding (sp) plug tips you mean ? if so yes as the normal type can act as a hot spot.

You wouldn't happen to have a spare shrader valve for the fuel take off would you??
Just rang John noble motorsport to see about a dyno tune they've quoted around £180 for a set up
My car spec as is....
Standard I think apart from..
Medium fmic
Baileys chav valve
Parts to be fitted..
Saab reds
3" downpipe
Rs turbo plugs
Zex wet nitrous kit 25/50/75bhp jets
Parts wanted
Phase 2 maybe 3 chipset
3" intercooler pipework
3" tophat
why saab reds? std lets are good for evo 5's....

Just got them pretty cheap.. And iv seen a few people using them.... Do I not need to use them?
I'm not looking for massive power tbf 250 would be nice...
they overfule unless you have a huge amount of air going in. on a std kkk youll be fine on std injectors.
Don't fit the injectors unless your on a adjustable fuel pressure regulator.
Also forget the dyno tune for the nitrous, just tune it yourself
I've got a LET ecu with a Evo 5 chipset if your interested

Jonlem you have pm.
What jets would be "safe" on a c20xe.

Mines gonna be for the mile and road use so I'm pretty sure I'm staying with 50bhp shots
Tune it myself? Help/ suggestions please?
I think I'm gonna be selling the Saab reds then tbf not going down the new turbo route untill I need to.
