I know a certain person in this thread that has a few choices of turbos lying around

He's a turbo whore and chops and changes whenever he sees fit.

Said person might even still have his ceramics if you just wanna do a swap.

Btw, inconel compressor + exhaust wheel FTW

Haha sure thing - you can try out my super-lag-spec R33 N1 turbos

All modern turbs have an iconel comp wheel :p Sorry Nick

[tommis85]

:P <-- there wasn't enough tongue

[TezGT-R]

Probably gonna get R34 N1 equivalents, high mount singles are scary cool looking but I'm lazy and low mount twins are a straight swap.

[tommis85]

Yep, good idea man...see if you can find a good set, but if not you're much better off going for a set of new (but equivalent) GT2860-7 turbos or their HKS GT-SS equivelant. If you don't mind a tiny bit of more lag go the 2860-9 ones like I did and you will never look back. They're good for around town, but when it comes to the QR straight they will put smile on your dial They are pumping very hard where the ceramics simply run out of puff and rpms.

All day every day 290-320kw with them (on average)

[tommis85]

A lot of -7 peeps make around the 280-310kw while the -9 guys will make around 300-330kw or so....bit of an overlap with these two turbos. They're very alike...the -9 is just trimmed up for an extra 30-50hp or so a bit more top end.

[TezGT-R]

Looks like a set of -9s, may as well get them this time instead of wishing I got them later.

[TezGT-R]

Was looking at these http://www.kudosmotorsports.com/catalog/garrett-turbocharger-set-garrett-gt2859r9-hks-gtss-nissan-skyline-r32-gtr-r33-gtr-r34-gtr-rb26dett-p-835.html

[tommis85]

HKS is just a bit more expensive and comes with a higher rated actuator in most cases. The ones that come with the -9's will need at least 7mm of preload dialed on to them to make them work well - but I can give ya hand with that when the time comes. (Even with a EBC you will still need to wind on the preload or else the wastegates will open at like 6-8 pounds lol giving you a very lazy set of turbos!)

The -9's are definitely the new -7 if you know what I mean....most peeps I know regret having gone -7 after going in a car with -9's.

The -9's have the pull and lurch of a single turbo....whereas the -7's are often described as being very linear. Depends on what you like I guess.

[TezGT-R]

The -9s sound like more fun, I'll start harrassing you for help when the time comes, thanks.

[tommis85]

No worries man...you'll love them. I'd recommend them to everyone who wants the 300kw.....easy mid-12 second car or lower

[me_larr]

All modern turbs have an iconel EXH wheel :P Sorry Nick

Fixed

Comp wheels are mostly aluminium or steel.

Forgot to mention, my turbo has the optional Titanium alloy exhaust wheel

Wouldn't you guys rather a more responsive turbo? So in this case the -7s would be ideal?

I always thought people went for linear power/greatest area under the curve so correct me if I'm wrong.

Laggier turbos move the power band higher up the rev range and by then the RB26 would be filling the catch can pretty quick.

But will it beat a dirty pushrod V8?

I'll argue this all day, I've never been a fan of "response" if I had a turbo it'd be the biggest laggiest power delivering piece of gear.

This is why I have a cam that makes no power until 3800 lol

[tommis85]

Yeh you're right 180Nick, the more meat under the curve the better. Mine are -9's...you've been in it

Some peeps can make these come on almost as early as the stockers which I find quite amazing..

...but if I ever have a 3L it will be getting the big single treatment

[me_larr]

You only have 2?3? gears anyway lol

You stay in your powerband longer especially with that long arse auto diff pinion and crown ratio of yours.

Horses for courses

Response is where it's at for me - which also happens to be where I spend most of my driving 99.99% of the time.

Here's a link for Terry to make up his mind. Has both sides of the fence and no clear winner

I have 4 gears with 1-3 being identical to a th400 and also have 3.6 diff gears, hardly moonshot spec! Thank you very much lol

But I also have a 3k stall so it's straight into powah!

Couldn't really feel any lag simply because I wasn't driving it nor was I looking at the tacho.

I think my comment after being in the driver's seat would differ though.

Having said that, it's a bit too scary for me. The sudden surge is brutal!

[tommis85]

Oh that thread hehe...there're a couple of those in here. I think I have spammed all of them lolz

I spent a good 2-3 months just reading, reading and more reading - one of these threads is mine too. Worse still are the twin v single threads haha

But I also have a 3k stall so it's straight into powah!

...straight into wheel spin

[Captain Natro]

Oh...straight into wheel spin

Yeah, but.... Looks tough

[me_larr]

...straight into wheel spin

This +100!
