So bro, (op)

What happened to making the decision yesterday?

You have all the information in the world. All of us have elaborated so much in this thread, that you should know by now what you would much rather want.

Have the invoice on my work desk. Will be paying for a set of -9s first thing tomorrow morning

Take care of michaels car

good friend of mine

Ahh thats the michael u mean. Bout to start swapping his turbo's over. Then injectors and a tune. Should make a little bit more than the 210kw he has at the moment

[Hadouken]

lol, and when he bought it the guy said it had 250. loool

[DVS JEZ]

Haha yeah he told me that. I always do a run before upgrading parts or a retune

[Hadouken]

Thats why your the pro

[J - Rad]

Well here is my -9/GT-SS result from today

nismo 600cc injectors

044 pump

hks cam gears

greddy front pipes + kaki regu cat back

[Hadouken]

280 something at 18 psi...

Stock dumps?

Afm's maxing out?

[J - Rad]

No Greddy dump/front pipe extension. Standard AFM maxing and I didn't want to push past it. I'm happy with what it makes and it pulls like a f**king train all the way to redline. Thinking of going Nismo AFM later and playing with the cam gears a bit more to make it more responsive, while making a bit more power.

[levinboy]

Defenetly upgrade your AFMs will be well worth it in the end

And double check you have a good cat in the exhaust so it doesn't restrict you too much

[J - Rad]

Which is what I don't have. Need to sort out a big 4" high flow cat or something.

Which is what I don't have. Need to sort out a big 4" high flow cat or something.

You should be into the 300s with 19psi

That would be choking your setup and a quick simple install and retune and car will feel

Even better

[sydking]

De cat....

[levinboy]

De cat....

Haha I wish only for the race exhaust

Side pipe

[J - Rad]

Well it does have a stock bashed cat.

Okay, bumping up this old thread!

-9's look like the best for the response.

However, if someone was to go -5's and threw in some Tomei Type R cams, would we still be talking about this huge lag?

I'm pretty new to this, but I would think a set of cams built for response could indeed reduce this lag? Maybe even Mine's cams hehe

[N1GTR]

You simply won't be able to to put cams in to combat the size of the turbos when talking about those two choices. Yes that big difference in lag will always be there although you may reduce it by a bit It's not going to go away completely and won't ever be equal between the two turbo choices

A set of -9's and low duration cams would be heaps for the street.

Larger cams will not magically give you 500rpm better response on the street or on/off throttle.

[levinboy]

before

After

built engine 272 cams only thing changed between charts is boost

[Piggaz]

Huge cams for that turbo and engine setup!

[R31Nismoid]

330rwkw @ 16psi up top & then drops to 300rwkw @ 20psi up top on the 2nd graph (4psi more, 30rwkw less!) - If nothing else was changed that is very interesting!
