32 GTR turbo selection

[Boosting]

Hey im bored and got money so i have decided to sell my 32 n1's turbos for a nre b/b set of either 34 n1's or something else prob is what is something else im looking for something that will bolt on the factory ppostion but if i dont go for the 34 n1's something that will make more power, not to worried about lag so i was considering maybe 2540,s with a set of cams would this be wise...

and question how much are 32 n1's worth these days..

A/r 60 steel wheels

you will get about $1000 -1500 for your N1s and I would go for the GT-SS.... that is what I have, and make 1 bar at 2900 rpm and they haaaaaaaul!!!

[Boosting]

I know the 34n1's are rated at 320hp each what are the gt ss rated at, or are they just a response turbo, i reaqlly want something that pulls all the way throught he rev range at least as much as possible anyway.

2530's.. if your considering twin 2540's.. go a set of GTRS's maybe? either that just some 350 garrets

im possibly goin twin 350hp's on my car

I'm doing something different......mainly due to a few people getting pinged for import duty on Turbos thru Nengun and the like atm.

Anywho I'm getting my standard turbos rebuilt using Steel T28 Wheels, and having the Housing Machined, costs just over $1000ea to perform....should see 600fwHP which is probably 100hp more than i'll ever use

Did the same thing to my old 'VLT T3' was good for almost 400rwHP, and is still going strong after 2+years.

I will post results when complete

I got my GTSS through nengun! and a whole stack of parts... no duty or GST!

and your T28 will still be plain bearing.... go the HKS, far better, and longer lasting

I wouldn't go running around advertising that fact. Regardless, you have to at least budget for the possibility when buying from Japan (US is a different story post free trade agreement).

I wouldn't choose the GT-SS's if your after more power than the N1s. I would choose at least the 2530s. 2540s = a mismatched turbo, so avoid (do a search for more info).

Attached is an old dyno chart published in HPI comparing a HKS 24030 with a 25-40. Not sure what you are after, but the 25-30 wins my vote. The turbos were fitted to an R33 Gt-R

Is it possible to see a modified version of that graph with rpm instead of speed ? I'm interested in the response of the 2530's but I'm not sure about the GTR gearing.

Dyno's charts are done in either 3rd or4th gear which is 21.9km/h per 1000rpm & 28.5 km/h per 1000rpm respectively.

The larger 0.6 AR front N1's are good for more top end power. I have the plain bearing group A's and at only 13.8 psi they can make around 400hp at the treads easy with cams (I have detuned my engine for a safe 370rwhp). If you wack the boost up to 20 psi with a better intercooler you could see as much as 500+rwhp. At those levels your engine needs to be made stronger and even before that an oil cooler is nice to have.

might just need a set of cam gears injectors with airflow meters and get a tune i think.

cause mine has made 400hp at 1.1bar injectors maxing out

would i see much of a gain if i did these mods with a tune on my fc

[rev210]

I'm running 700cc sard injectors, cams are tomei 260's and standard airflow meters. The Standard airflow meters run out of resolution over 400rwhp and it's easier to tune with something bigger like the Rb20/25's and they are a straight plug in. If you are shooting for more than 500 then Z32's are the shot. If you have the 0.6AR front N1's you should be able to get more out of it with bigger cams.

whats the web site for nengun performance

[Boosting]

yeah i do have the a/r 60 n1's something i have to look into thanks

i'm running the gt2560r garret 320hp (r34n1) they have 0.60ar compressor and 0.64ar turbine housing and with pfc ,z32afm ,700cc sard injectors and poncams i make 529.4rwhp at 20psi .The gt2560r are very similar to 2530hks with the same turbine but has a differnet compressor ( i my opinion an awesome turbo combo for the gtr).

The 2530 hks is also an excellent unit also.
