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.

      I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?

      Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?

      So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
