Buying Some Mods For My Gtst 33

[Stealthynsa]

I'm starting to get all my parts together for my conversion,

so far this is what I'm getting / already have.

Rb25det engine, using a r32 gtst gearbox as I already have it. (yes I know they are weaker)

Z32 afm

apexi PFC

3" turbo back exhaust

Justjap fmic

turbosmart dual boost controller

pod filter

I bought a turbo from my mate,

Nissan front housing with Garret gt30 front comp wheel with a ar63 rear

(hope that sounds right as I got it ages ago)

I'm hoping for around 220rwkw after the dyno tune, "what's your thoughts?"

do u think I will need to upgrade the stock injectors to achieve this?

And is there anything else u think I should get before the dyno?

(would cam gears get me anything?)

Have you invested in anything for the fuel side of things?

Possibly a fuel pump depending on the condition of your original... usually the first thing to go once you start placing pressure on it! The stock injectors will get you to 220rwkw ... but a Fuel reg with supply some breathing room before having to upgrade the injectors.

I got to 230rwkw with an FPR, aftermarket pump (mine died under pressure) and a slide high flow turbo before the injectors could do no more... well safely anyways and that was with only a SAFC2.

I personally wouldn't bother with cam gears at this stage.. but that's just me.. I'd make sure the fuel delivery is up to the task if your budget is limited and its one or the other.

yep a biiger fuel pump and injectors and u will have no troubles, even a surge tank would be good if u ever decide to boost it up higher

[Stealthynsa]

Ok so just a fuel pump or a fuel regulator aswell?

And what pump/regulator would u recommend if later I wanted to up the power some more.

If I buy both of these do u think the injectors could last if I tried for over 220?

Bosch 040 for intank and ease of install... I have had a bad experiences with walbro's so I am biased.

I went a Bosch 044 (external) and stuffed around mounting it in tank. Any decent brand FPR will do... I remember I picked my Sard one up for under $100 second hand...

Once you start getting more power, and trust me you won't stop at 220rwkw if the bug bites you (mine was going to stay at that!) you would be looking at external setups anyways.

Even a GTR fuel pump is better than the standard Gtst one...

The injectors will go a little further, but I wouldn't run then at more than 90% duty cycle. Each engine is different so a figure for rwkw isn't really easy to give... your tuner shouldn't take the car past what is safe anyways - well hopefully!!
