ok so as a p plater i dont really have much of a choice in making my car more powerfull, and with 2 and a half years left on my p's i wont be for a while. so i have been looking into better air/zorst flow for my sr, and have found these http://www.efihardware.com/products/687/SR...et-tbore-525048 i allready have some hks 4-2-1 extractors but want to go even further with my sr20de so has anybody had any experience with this sort of thing and how much of a difference does it make with response, power ect cheers, milan.

They will lose power(but makes heaps of cool noise) unless your have more than 12:1 compression, big cams and a REALLY good tune. |

You wont make power that is huge, you will make the car fun to drive, and rev to all buggery, but just don't expect that push in the seat effect that a hi torque motor will give. You could set an s14 up in na form to be a weapon on a mountain. My AE86 was able to sit up the ass of Mcleods WRX with just 62 rwkw from a 4age. Stop thinking power and think throttle response. |

Stop thinking power and think throttle response. yea i always knew non turb sr's will never make much power, just wondering if the throttle bodys WIll give the extra response and to rev higher than 7k. i looked up the tomei ones and they are only for the non nvcs sr20 and they are like 2.5k compared to then efi witch is 1400 obviously ill need a am ecu injectors ect but will this all be worth it? i was talking to the guy at archy with the na ca auto sil and he told me about these, he was saying hes making a invincable sr and was geting these itb's for it and recomended it to me. oh and i have never drifted before, thursday coming up im going to have my first crack at it on archy with the standard sr na. got a bad feeling about it but i really want to start drifting lol, |

Tomei kit can work with a stock retuned ECU in Alpha~N mode and they can be supplied to suit the NVCS S14/15 motors |

errr.... cops tend to notice ITB's. 4 big fat filter socks on the end of the trumpets = defect city. Especially if they are anodised blue. |

lol i had this idea of making like a plastic cover to go over the quads and keep all the original box and pipes in place make it look stock to the everyday no clue pig... paint everything in black and tuck in anything that looks defectable... |

^^ Exactly. Having ITBs doesn't mean you need to have separate filters and no airbox. Once you're at WOT they are essentially just an intake runner, so there's nothing stopping you running a standard looking plenum fed through a single filter box. If properly designed you'd also get some power gains over straight trumpets from intake tuning. |

I looked into this when I had my s15. I was going to buy a set of tomei ITB's. |

PS: Dont waste your money on the EFI Hardware ones, the Tomei ones are a direct bolt on and are much better value(plus stock injectors in the fuel rail, TPS works correctly, etc) You seem to be forgetting the massive midrange that comes with itbs. Bolton itb's with a tune (stock internals) on a b18c made an average of from 10-20kw in the midrange, lost 2kw at highend. |
