9k RPM turbo

[Reaver]

Well, I am building a notch top s14 sr20det with solid lifters/built motor to support a 9000rpm redline. However, obviously I don't want to only make power up to 6000rpms/7000rpms whatever with the turbo. I've heard of plenty of people doing this to the SR's, and despite what people think I've decided to do it. What is the ideal turbo I could use for this to make power up at 9000rpms? Anyone done this and been successful...I know there has been one person on here that's done this. (By the way this motor is going into a 240z). Btw, I'm looking for about 400-450 RWHP. I want the turbo to fully spool at the top of second gear at the latest. Anyone have any experience with this?

I've already read that. I know what he did to prep the head, and that's no issue. I need to know what turbo set-up/turbo I need to use to make power that high. Thanks for the info though.

Maybe get a top mount 3071r ir 3076r. If you want even higher top end power you can go with a 35 series turbo too. Also you can get the Full Race twin scroll kit which will give you a good spool time, and also keep pulling all the way to 9k rpm.

What price range are you looking at? Have you decided on what manifold you are going with?

You can take advantage of twin scroll and get a larger turbo that will spool quicker. Something like a 3076r will get you 400whp and will spool amazingly quick.

No, I haven't decided what manifold I'm going with, and the twin scroll idea I didn't think about. That makes a lot of sense. Price is really not an issue. The budget for the built motor has been taken car of, turbo budget runs around 6-8 grand.

the best way to learn this, is to learn how to read compressor maps.this will allow you to predict exactly your power band and boost pressure at each RPM.

but the advice given above is effective, garrett turbos like the gt3076 and 71gt35, and even big t3/t4 hybrids are all good turbos for the amount of Air you're going to flow at those rpm's.

( laggy turbos are also better on gas when you drive locally and below 3k... just sayin )

Holset H1C, HY35's, and 40's are also very affordable and many other truck diessel turbos that are often overlooked

but compressor maps are better then our opinions.

To get power made @ 9krpm you will need a T4 sized turbo with a 67mm or larger compressor inducer with a .6x or larger turbine housing to keep the backpressure down at high rpm. Its gonna be laggy and i recommend nitrous for a decent powerband. Also dont forget about a set of Tomei 280 Solid Cams. If your seriously going for a 9krpm curve, your looking at 700+hp said and done.

If your only looking for around 450-500whp, stop looking for rpm. Do a Twin Scroll GT30R and rev to 8000rpm. The tq from the TS setup will make all your HP within that powerband. Revving any further is unneccassary stress on the engine.
