Oh no. Surely you aren't seriously asking that question and only giving 'pull hard' as your goal!

[r32-25t]

Gtx45 will pull like a demon

[GTScotT]

You are looking at spending 10k to have it pull hard..

You will spend a lot less if you get your stock turbo highflowed to the right profile, it will definitely give you the pull hard effect and will cost you a lot less.

I reckon a Hypergear G3.5 highflow will do a good job of the desired task, the delivery will give monster pull without being a pig to drive.

Before you ask, you will need a full 3" TBE, FMIC, fuel pump, injectors and an ECU at a minimum.

Nothing pulls like a 14 year old.

Nothing pulls like a 14 year old.

Spoken like a man with years of experience.

Haha thats "GOLDEN:)

[Gamble1990]

Got injectors coil packs Fmic 3" all the way through fuel pump, buying a front facing plenum, adaptronic ecu about to get a tune as soon as I can decide on the turbo I want 400-500 hp atw

At the moment no one has given me a answer or opinion on what one would be more suitable

Look at the rb25 dyno results thread. It's not rocket surgery. People don't have to tell you what to do, you can figure it out yourself sometimes!

[Dale FZ1]

It's not rocket surgery.

It's not brain science either.

GTScotT is offering some sound, experience based advice. He's also considering the driving outcome and financial aspect of things.

However if you are chasing a 500rwhp setup you won't likely get there with a GT30 setup. Go the GT35 and be mindful of people's comments to this point.

the GT35 will be like a "brutal quickie" ,

Yes they have...this:

and forget the GT35

3076 56T with a .63 on E85 hits like a sledgehammer...

the hypergear stuff in same size are a more linear pull and deceptively quick, but probally faster no doubt

guess it depends what you after, i have no idea what a 3450 feels like on a rb25, only 25/30's and 30s's

guessing boost response would be fairly bad on a manual

cheers

Glad you put that 3 inch cooler piping, talk about overkill. You can make an easy 300kw on 2.25 inch piping.

Stop slapping parts on and read, there is so much information here you should be able to work out what you need, then see if you can go for a spin in a few members cars to get a feel for the response. I am guessing the GT35 will be a little too laggy if you plan to drive it daily.

[JordansR32]

Gt 3076, .73 rear eflex pulls hard

[Gamble1990]

thanx for the help people goin the 30 size. but super ben is a bit of a smart ass

[Ben C34]

Lol, sorry for suggesting you provide more info on your goal, then pointing you in the direction of a thread with all the info you need All the best with the build.

Read this thread - ultimate RB "pull hard" setup, make numbers in the range of GT35R peak power but spooling similar to the smaller GT30 range turbos:

[RBrennan25]

+1 for lithiums post. HTA turbos are weapons and will give you the best of both worlds. Will give you 400rwkw and the same response as a gt3076.

You'd be mad not to have a look basically
