Gtr Turbo With N1 Internals Or 2860-7 ?

[Mr Cali]

HI,

Just need some opinions and experiences of you guys.

I'm replacing my turbos due to my turbines ending up in the cat. I have two options and needing your help to choose.

1. R33 GTR turbos freshly rebuilt with N1 internals for $1450 comes with 12mth warranty.

Specs: 360 degree Thrust bearings

VSR / Hi Speed Balance

Nismo / N1 41.7 - 53.0 Spec Steel Turbine

Pros: Can be tuned upto 300KW ATW, $1000 cheaper, relatively low lag similar to stock ones

Cons: Don't know anyone thats had these and experiences, bush bearings, and pretty old tech turbo.

2. Garrett 2860-7 brand new $2400

Pros: New turbo, ball bearings, tried and tested and sworn by many modders, hardly any lag

Cons: $1k more expensive

Now I'm torn between these 2 as I'm aiming for around the 300kw and both are supposed to be able to do this. It will be a daily driver and will only see the occasional track maybe once or twice a year if that. I don't usually hoon around town with only the occasional spirited driving.

My main concern is responsiveness, and top end power will always come second to that as I will hardly be opening her up that much.

The delema is the $1k difference in price tag, and as you all know swapping turbos over can be an expensive job. Will the N1 spec one give me what I want or am I just wasting my time and money going down this route? Upside is if I do this, I can spend that money in tuning time with the Power FC (which has not been installed yet). Will I get a noticable difference in performance?

All thoughts welcomed

I'd take the -7s. they will make a little more power with a little less lag.

Unles the difference in price is a big deal of course. the 33 n1s are OK but older tech, bush bearing etc. $1k probably isn't a lot in the total cost of modding one of these. Another option might be 34 n1s they are ball bearing.

BTW I run the r32 n1s due to race rules and they are OK with a bit of work - but newer BB turbs are a better idea.
