So i got this a year and a bit ago off the guy next door because of the broken trimatic. It came with a black 202 carby in it with exhaust and a little work, under 500$ i thought why not im keen for a project. So here it is an 85' VK with decent condition interior and a bit of rust, just another car to the house So the goal for the project was so slip an rb30 in while keeing the inside and outside looking stock i grabbed an rb30 complete engine, intake and loom with ac compressor off a mate for 250$ it was out of a vl wagon but he sold the turbo gear. Then my other mate that drifts had a spare stock rb25 engine and box out of his mates crashed r33 skyline... So he sold me the complete head loom and box for cheap.. But thats for later So goal is to build a fully forged rb30/25 setup running decent turbo gear for a sleeper street car aiming for 450hp at the wheels. I also have a VT break upgrade ready to go on, a vl kframe and engine mounts, and a VL fuel tank. I also have a mint condition blue interior just like my stock one i found for 80$ with all seats, dash and everything. So now it was time to start this thing with getting it straight! One whole week to strip and put this thing in primer was all it took every afternoon after work, with a few extra days to source a new bootlid as mine was full of rust.. All the panel work was done by my mate who is a panel beater by trade at his house then off to his work for paint in booth. then to my mate Cromies around the corner {who sold me r33 stuff} to get my front guard ariel shaved and a little peice of body welded up Then before we started to rip this trimatic out to replace with a new one (to get regod after paint with stock 202 and box) we did a skid in it after some beers were had good times Final outcome, straight as then celabratory beers and fire in the street Now to source my secret paint colour then off to the booth, then the engine build starts, will keep you updated Some original photos have not been recovered yet.
