I have upgraded my 240z brake booster with electrical vacuum pump, connected direct to brake booster, works great no issue

I bought rb25 pan and modified it Check my building http://forums.hybridz.org/topic/123114-golden-rb-240z/?do=findComment&comment=1151028

better to go with R33gts or s14 crossmember, approximately 2inch wider

I think the best choice is lexus ls460 output 350amp

with the amount of power RB26's will be producing and considering future upgrading I have to increase fuel system efficiency setup that will be up to the task of delivery enough fuel. As well as, I wanted a close to stock looking boot .First I modified spare well pics are in previous post. Second, I modified tank, I striped all the old hoses and sending unit. Then cut tank’s upper half and clean inside tank, plenty of rust shuffled then I welded internal bars as a support to protect it from crashs and welded small plates as fuel baffle to protect fuel pump from sucking air and keep itself full at all times thus, prevents fuel starvation in cornering and accelerating. Fabricate new metal upper cover, welded and leak tested. Made vent line Bought Toyota supra fuel hunger and welbro455 fuel pump but for now I installed Toyota chaser turbo fuel pump just for starting and trial test purpose. drilled hole in the tank and fabricate two ring adapter plates, the lower one welded with bolts and wielded on the tank the other ring holder for seal hunger. The pump right now sits about a half inch from the bottom of the tank, it should be perfect. I also upgraded old rubber filler nick and cap with 1.5 inch flexible steel hose one end welded into the tank hole the other end fitted into rubber hose to cap’s nick and firmly clamped at both ends. I do have a pretty tank now

thanks dude

Dash had large crack holes, they were splitted the edges of the cracks flare upwards. I filled them with fiberglass then sand and flatten these flares down, then painted with plastic but cracks were in the typical places, and you could slide your fingers through them and may crack again in future. So decided to cover the dash with carbon fiber. First i painted it with epoxy resin and hardner coat to make it solid protected from any future cracking and flatten it out then layout carbon fiber cloth then put epoxy coat lastly, spray it with clear lacquer paint and do the same for all interior plastic pieces.

I've completed the body work and now paint time

Body work Replacing Passenger Floor and driver floor were very corroded.Also welded small rusty areas all over the body. I modified body seat base to fit 300z seats. welded support bars to protect body from cracking and for safety. Instead of using por15.I used cheaper and stronger tar paper roll 3mm, that used for sealing building roofs, for covering the floors from noise and rust. Finished up Shorten the spare wheel well and made removable fuel cover tab for custom fuel tank, then rewelded it back as nice as possible to give stock looking.

To overcome excessive heat from turbos in the bay, I chose to install 280ZX vents because they are bigger and have more holes to let move air out accumulated heat than stock 77-78 hood vents

Yeah bro, I've been working on it for about 3 years now my first thread was this http://forums.hybridz.org/topic/108582-240z-awd-swap/ got rid of stock clutch boost cylinder and Installed gtr32 clutch booster cylinder with minimal adjustment made aluminum glove box and it fitted perfectly

I bought aftermarket R32 front tension rods and nissan galoria aftermarket front suspensions. I modified suspensions upper part my removing top cup and machine plate same as stock size drill bolt holes then welding tack lock the bolts to not loosen when running. Fitted drums and brakes of r32 straight with no issue. Installed silvia aftermarket adjustable front lower control arms. They didn’t fit directly I widen the crossmember arm pivot points rack by around 7mm to fit arms’ pillowball. * Started the conversion to power steering gearbox from nissan. It fitted on stock rock nicely, but right rod was found short so I machined extension piece welded with right tie rod end. The stock swaybar not fitting with new modifications so I bought nissan slivia s13 front swaybar but it was wider than body by about 2inch so I cut it from meddle then shorten it from both side by one inch then welded it.
