Ive been pretty excited about this build lately, the S13 has always been that car that i favour, so much so that the last 2 years its barely moved. Im pretty happy with everything ive already done on the car but going NA means a few things must change, i have always loved Quad Throttles but never used them, i picked up a set of 52mm throttles and the cut up an old inlet manifold to join them together. Its all just tacked up for now but its getting there.
On the other side of the engine ill be building some long 1.75″ runners all merging into a nice 4 into 1 collector and then a 2.5″ pipe all the way to the rear.
I want this car to be clean and free of anything that isnt needed, i deemed PS to be not needed so i pulled apart the rack and investigated what i need to convert it to manual.
All that needs doing is drilling the internal piston to allow air travel from left to right, plugging all the holes, then giving everything a good grease and refitting everything back together.
Ive built a Jig to emulate the crossmember with a few important geometry changes. Ill be remaking the crossmember from tube and raising the LCA mount point 50mm, the rack will be moved 50mm further forward and 10mm up to combat bind with short knuckles, ive also built a jig to remake the caster arm with a few cool changes to it aswell.
In the long run i want to be able to remake everything that bolts to an S13 chassis out of tube.
Its going to be super clean, im excited to see what the engine bay turns out like.
