Looking for a bit of advice and help here, i'm looking to to fit this kit:
Welcome to my forum.http://www.noswizard.com/car-nitrous-ki ... -body.htmlIs this kit a good starting kit to build on for my car?
Yes it certainly isWhat size of jets can I fit?
The system is rated at 150 HP, which means you can use jets up to that size but we recommend that ALL customers start by using just 25 HP jets and work up from there in 25 HP steps.Is an uprated fuel pump require?
The standard pump 'should' be adequate for up to 75 HP but there's no way of knowing, unless you either test for the excess fuel capacity or monitor the fuel pressure as you ramp up the jet size. Above that you almost certainly need either an uprated pump or an additional stand alone pump.Can I fit a progressive controller, purge kit, bottle heater,
Yes to all the above.Nitrous bottle capacity indicator
Only if you order a Max X2 or V2 and for your information we may have a new old style V2's available at a reduced price. and or any other ancillaries to this kit at a later date and in stages?
Yes all our systems are upgradeable at a later date.How much power could i add, run with this set up, and please be honest with me...how safe and reliable would it be?
There is NO way of knowing how much 'your' engine will handle, as ALL engines have different levels of reliability but we've never had an engine fail at 25 HP (which is why we always advise customers to start at that level) and we've seldom had any engine suffer any problems at 50 HP.
Toyota's are generally good engines and you could probably go as high as 75 HP, as I'm pretty sure we've had similar engines manage that reliably but we can't guarantee that. Adding a progressive controller can increase the amount of power an engine can handle by at least double but that does depend on what settings are used.
WON nitrous systems are the safest and most reliable in the world and that is an INDISPUTABLE FACT and as a consequence that makes your engine more reliable when using the system. Furthermore, WON systems are the ONLY systems that have been DESIGNED for use on STOCK engines and as a consequence customers engines will be far more reliable than if they used ANY other brand.
