Great build man :thumbsup: has inspired me to drop a 25 into my 32 gtst to spice things up again. Are there any clearence issues with droping the 25 in as mine will be mainly used for street i would like to keep the a/c ect and can my power fc currently running a rb20det also run a rb25det or will i have to upgrade/swap the computer?? sorry for the newbie questions

The 25 is 18mm taller, other than that it's the same dimentions. If you get a s1 25, you can use the rb20 loom and ecu with a nistune and vct controller or z32 ecu (internal vct controll).

It's the best thing I ever did with my gts-t..

Yeah they fit piece of piss...

You could use the power fc with a vct controller but I would recommend a Z32 ecu with RB25 loom and nistune as per XRATED above :)

awsome build buddy. did you wire the 25 in yourself or pay some one if so how much.

No wiring needed because I'm running a RB20 ecu, loom and sensors... Just needed to buy a RPM switch to turn the VCT on/off (I used a Greddy MSS) and have that wired up which was pretty easy

Finally got around to doing the brakes upgrade.

Went from standard stuff to...

R34 Front Calipers to suit 310mm disk

RDA slotted rotors all around

Hels bradied brake lines

QFM A1RM pads all round

Looks a lot better now, fills out the wheels more and should hold up well for the time attack on Tuesday night.

Finally got down the track last night and managed a 58.0 at Barbagallo short track which isn't too shabby, also picked up the trophy for fastest RWD on the night :) Only revving it to 7000rpm and using 1.4bar on the track and everything held up mint with no issues at all!

Managed to lock up the front left and flat spot the tyre being way too eager on the brakes into the first corner early in the night and was going 0.5sec faster on every session so there is a lot more time to take out of that in the future. I used some Dunlop D02G 225/45/17 that were second hand and on the tread wear limit, I'll have another go on them next time and rotate the flat spot to the rear before I bring out some 235 RE55S and see what I can do.

I think I should be able to run a 56 with the Dunlops and try for a 55 on the Bridgestones in the future :)

i did not watch any of the vids or understand most of the words used but damn. alot of work and alot of love went into this car. almost makes me wish i had got an r32 insted of my 4 door r34 :cheers:

nice work

Just purchased myself front lower castor rod brace and going to get some front fender braces soon as well just to stiffen the old girl up a little more before I head back on track.

Also have a Hel's oil cooler kit with thermostat on its way to keep the oil temps in check when thrashing,
