sil25

as muh as i would love to crack the head open it is not a valid option at the moment because it is just to expensive. the extractors that i had made are tune lenght to match the cams, i also have a hi flow cat. I did some research into ITB's and couldn't justify the cost i went the Q45 option machined with a heavier spring. If this acts as fast as i hope it will then it should do just fine. to put it in no uncertain terms getting the air fuel ratio right was an absolute b#$ch. it took the best part of 2 months. forgot to mention that before 600hp fuel pump and unpgraded fuel lines. injectors are coming just looking for a good set of 440 or 444. made 170hp at the wheels with exhaust, wolf, fuel pump, pod. haven't done tune since the last round of work still sitting in the workshop, looking for around 270rwhp it drives amazingly. Very responsive, smooth as silk to take off and power band is very long due to the down low torque. I strongly recommend this transplant for anyone who love the NA hope that i answered all your questions keep the coments coming its appreciated and good to see there are others out there who respect what it takes to build a NA motor.

i've read a bit about grounding kits and voltage stablizers do these work much on NA cars if they do what sort of improvements did you get what sort of money for them? anyone had experience with them on rb25's think that they are worth having?

hi all this is my virgin post on SAU hope that someone out there can give us a hand I've got an rb25de powered silvia and am looking to get the most out possible looking for things that people have done or know work below is a list of things already done. any and all help is appreciated. custom made exhaust custom made extractors cams cam gears wolf 3D version 4 pod filter custom cold intake lightened flywheel heavy duty clutch Q45 throttle body looking for really responsive engine and some more revs any ideas?
