Neptune RTP/ Vitara 75mm Pistons
I have a Neptune RTP ecu I never got a chance to put through its paces. Its on a p06 ecu that is converted to vtec. The work was done by Xenocron and I simply installed it.
I want 450 for it plus shipping... Sorry no shipping overseas
Selling because nobody around here tunes it and I don't want a street tune.
Local pickup if you are in the Boston area
I will consider trades for a hondata ecu and I will give you money on top of it. IF IN perfect condition.
Anything else just offer me what you have and I will let you know.


Have a set of vitara pistons still installed in my motor, 75mm no miles, compression 156, 156, 156, 165. I can send you the rings if you want them but cylinder 4 has higher compression,... so bad rings, but let me know. I will have them out soon putting them here early $50 plus shipping including rings if you want them... Hastings rings.


More stuff coming soon

WOW! really.
A neptune demon installed on a vtec p06 for 400 is alot? I used it to start the car and thats it, its brand new. Pretty much getting a chipped ecu for free
I am going to have to say no.

Pics of the pistons and some history. The machine shop set my p2w to .0085 so the engine always smoked since the rings could not seal. Also because of the larger p2w the pistons moved a lot. Thats why they have those scratches on the side, The rings where also washed out but with a thorough cleaning they should work fine as well. I never drove the car since it never worked.
