Gtr Mods ?

[GTR_NUTZ]

G'day all. I a R32 GTR and like most people I want to change a few things here and there, but I want significant power gain for the money that I'll be spending. Engine rebuilt a while ago and currently running 2560's 3 inch cat back compression standard and head work...

Before I throw the PFC in and get a tune done i want to know the following...

First things first, dump pipes and down pipes. Is it worth the headaches and money changing from stock to aftermarket? Will I notice a gain?

Z32 AFM's, I will want to up my boost, so should i just bite the bullet and upgrade from stock, I've seen the Z32 AFM's with adaptor plugs, will they do the job and hook straight up to stock piping? (I'm pretty lazy when it comes to making things work)

Last night and all this morning I've been looking at injector mods on SAU, and after reading a shat load of threads and comments i still have no clue where I should start. I'm not too keen on FPR and new fuel pumps, rails and blinging up my engine bay. Something decent and something bigger is all I need, anyone have any suggestions?

I've been keepin a eye on the oil catch can thread they seem like a decent i dear, ive alwayse wanted one so I'll have one of them soon too.

Any feed back would be appreciated!!

Cheers, JUSTIN.

If you don't want massive power upgrades I read that rb20 afm can be used and they are cheaper

First up.... Do a search everything has been covered before in depth.

1. Yes front pipes and dump pipes will be required for more power.

2. If you want to run z32 afm you need to change the intake piping aswell. If you don't want to then buy nismo items.

3. Buy big enough injectors to slot into the std fuel rail.

4. You don't want to buy a fuel pump.... Doesn't matter what size injectors you have if the fuel pump won't flow enough. Fuel pump is essential.

About Dan's point 2.

I have done 2 R32 GTRs now with Z32's and stock setup. I just redrilled holes in the stock airbox to mount and seal Z32's.

The stock intake rubber piping will stretch a bit to fit the Z32's as well.

Thats pretty cool info re the streching, valuable post in future with Z32s coming down in price lately.

Thanks,

Your gonna remove your turbos to change the dumps? That should of been done while the engine was out

Also I wouldn't push the stock fuel pump too much
