thanx guys, i will try my best to keep it up to date:)


ummm holset compared to garret...

well the particular model i have gone for is apparently between a gt2871 n a 3071

bush bearing compared to garrets ball bearing

but ment to give better response due to a superior blade design or something like that

this one is only oil cooled but shouldnt be an issue

the physical size is larger than a garret

can handle upwards of 35psi as they are designed generally for trucks

should be nice to drive without to much lag, my goal is around 350hp at the wheels somewhere around 17psi

nuclear_z - im running an australian built ecu, Adaptronic www.adaptronic.com.au great unit, lots of features should be fun to play with, yeh i had 315 at the rears of my silvia which was nice but could go a few more:) dont really wanna look at forged internals right now so ill be happy with 350 and some nice response!


JP - ill take a photo of gearbox mount soon, i havnt actually mounted it up... that photo was engine resting in there only to check few fitments but im planning on getting gearbox in there with the engine soon:) it is a Castelmaine Rod Shop Gearbox mount.


RBZ 260 - thanx mate, trying to make her perfect in my eyes:)


sco_aus - ahh... yeh wage isnt great but i purchased my silvia with a 15000 loan and when i sold that i used the money to buy parts, not pay the loan off:P but yeh she has cost me around 28000 in parts so far haha hopefully by the time 35000 comes it will be a real nice car on the road not on my lifter

Now those electric windows ARE nifty!  Mind telling use how much they set you back?  ;D


cheers man, they work awesome!

i picked them up off ebay, a seller in australia. Generally go for around $250 which i think is well worth it!

Your door looks different to mine... I had to mount the locking unit completely different because of the windows. I shoulda installed power windows first so I wouldn't have had to find a place where it wouldn't jam... ^^

yeah minesis a 3/76 and has the same as yours. this one would be prob the late 76 or 77 78. cause i was looking at central locking as i had few difficulties mounting it. this seemed easier way but the door definetly different.


some things remind me when i was working on my 2+2. the pedal box clutch accelerator cable all very similar to mine. works well so u on a right track. ( i just wished i went the next step and installed with ABS, oh well something for the 240z.)


not sure did i see power steering on your list?


i cant wait to see this thing completed.


that power window kit looks like a very easy fittment. may have to look into this and removing my heavy 280zx motors to adapt this kit.
