Difference between turbo's?

[Bennjamiin]

Hey guys,

Still learning a lot about the internals of cars and I know it's a bit of a silly question, I tried google but I may have been using the wrong key words...

Q. What is the difference between -5 / -7 / -9 etc turbos?

[Hadouken]

Nothing. There is also definitely not a forum over a 100 pages long covering this.

So insightful, new to forums, tried searching but to no avail, appreciate the sarcasm [emoji108]

Seriously dude. There are 3 topics that get covered over an over.
What are the first mods I should do
What clutch should I buy
What's the difference between 7/9/5

Probably would have been better to just point me in the right direction would be happy to follow a link to the answer and delete this thread.

-5 and -7 very similar and the most responsive turbos for a street car. I think -9 make a touch more power. -5 make a fair bit more but are considered laggy on a stock stroke rb26. Check out the rb26 dyno results thread.

Cheers mate, I know what the difference is in terms of power and lag, was just more curious as to what the numbers meant as in corresponding to the certain size of something

Not googlable topic at all.

Thanks for the info

Just the number Garrett decided to stamp on the end of them. There is also a -10. Doesn't really mean anything. If you look up the wheel size specs for each of them, that may give you a better idea of what the differences are. P.s don't worry about Hadouken, he drives an EVO. Sad state of affairs there. Lol.

It's more like:
-7 are like N1 stock turbos. Nice upgrade with not much change in spool capable of running more boost reliably.
-9 are a step up from here but don't come with actuators so end up more pricey than -7 or -5
-5 are pretty serious turbos and come with the resulting lag (5k rpms start powerband)
-10 should not be used IMO. Way too much lag and much better other alternatives.

Streetcar that will only see pumpgas -7 all day.
Streetcar that may turn boost up on E85 -9 with good aftermarket high pressure actuators
Race or track car looking at 500+ whp (or a stroker or RB30 car) -5s.
