1990 s13 rb25det series 2 build

[1990 240sx Rb25]

I decided to start a build thread of my s13 rb25. This is my first ever build i have owned a mk3 supra and a 07 sti. This is my car when i first bought.





Heres a shot of the engine bay from the mess of wires to the exaust intercooler piping



And the hack job continues



So i drove it around for a while passed emissions started to practice how to drift clutch kick and all the fun stuff along the way i cleaned it up.




Painted all the trim back to stock black. it had a horrible paint job so i decided to return it to stock look i also re-sprayed the interior black to clean it up.

Then my car started to smoke so i went and got a used turbo and my buddy helped swapped it out and also put a new battery in the car with relocation kit to the hatch the battery in their was 7 yrs old.



So as i was doin the battery relocation kit i decided to clean up my in intercooler piping and make it shiny and the the nightmares started coming i found i need all new intercooler piping. it was rubing were they cut the frame to route piping.



And then the new parts started coming from vibrant intercooler piping to front facing manifold to the 3 gauge vent holder to a tial q/r bov new front bumper,nrg 2.5 quick relase, short hub and steering wheel, oil catch can and broad way rear view mirror.











So i tried doin the intake manifold my self and i did have the proper tools or the time with work so i brought it to ecs performance were they put it on and found out it had to be machined flat cause it was not sealing right so i also had it powder coated black and at that time i had all new intercooler piping re-done. After all was said and done my car still smoked so they did a compression test and found out cydlinder 2 had bad rings so i purchased a new motor from tiger ***.

This is my attempt at putting it in








thanks to ecs its alot cleaner this is the old motor



and then i bought a new motor horrible pic and they put the motor in also bought a new exedy clutch stage 2 re-machined fly wheel and throw out bearing.


This is the most up to date pic i have we still cant get it started it cranks but wont turn over were guessing it the old hacked up wire harness.



it has came along way since i bought it in may of 2012 just need power steering and i can be out at this yrs events.
