Some people have that and make 380kw.

It has something to do with the turbo choice.

Bigger turbo isn't very specific. I assume it's hardly hardly any bigger and that explains the the power.

Bigger decent turbo.

Much power.

It's a turboneticts t66 it's much larger then stock

That's why in op I said I think my turbo is outdated but it still does the job was thinking a gtx3076 and wanted some turbo advice as well on what is a good turbo for 300 if not more

That turbo is capable of 430odd kw, any reason you want that particular one?

[jeffero69]

Well I figure if I want to push for more power it's there Instead of another upgrade on top ?

[Ben C34]

T66 should be able to make more power than what you are currently making.

I can't beleive Scotty hasn't mentioned E85 yet!

if that turbo is capable of that then build the motor change the injectors....tune ....skidz on.

[jeffero69]

I believe it is capable of more power no drama but it's going on 6 ish years old now

I am trying hard... But I don't want to scare him off with information overload.

Do some research, it will save you a LOT of heartache.

[jeffero69]

I just figured for the mods I have now and the power it's making it doesn't make sense

[Badgaz]

buy some injectors off scott...i'd do that first....you'll probably run out of injector first.

[jeffero69]

One forum I was reading said 550cc injectors were good for 350kw

[scotty nm35]

Depends what fuel you are running.

[jeffero69]

Just 98 out of shell generally

[Badgaz]

once they operate over 80% duty cycle they become less efficient. if stock 440's are good for 260kw i can't imagine 550's would go much higher....although...you could search...its probably here somewhere

[jeffero69]

[scotty nm35]

I still don't understand why you expect 300kw at 14psi...

Why didn't you wind the boost up?

[jeffero69]

I don't at 14psi don't get me wrong if just wanted to know what other supporting mods I need and this was the tune that came with the car I sold it to a fella who put a bigger front mount on tuned it to this and 6 months later I have brought it back

[iruvyouskyrine]

Okay Jesus Christ this is a roller coaster.

Keep your R33 head and slap it on an RB30 bottom end.

Keep your turbo.

Buy X-Spurt 1000cc injectors.

Sell your Power FC and buy a Link/Haltech.

Keep standard intake manifold.

Keep the hot side (turbo side) all the same.

Get it tuned by a REPUTABLE tuner. Run it at 20psi and enjoy obscene amounts of power, who cares what it makes, 300kw is just a number. I guarantee you will be happy with whatever it makes.

This is the best/cheapest/easiest/least f**king about way to do what you want.
