cheapest bet is to buy a rebuilt pair of stock gtr turbos with steel exhaust turbines - can be done for around the $1350 mark from a bloke in Melbourne I know. PM me if you want more details

yeh a guy on ebay got n1 turbos with all gaskets for 1350 on ebay thinking that

thats a good deal... kits like that are pretty painless to fit (as far as turbo fitting goes that is), you might need to buy some new lines and studs maybe but once bolted up, all you should need to do is push more boost thru - do u have an EBC?

Edit - incidentally, the N1's will give you that extra power, as they can be boosted past 14psi, right up to 20-25psi (not sure when they run out of puff)... stock gtr turbos are limited to 14psi and only produce 180-220kw safely... you'll easily make 300 with N1's, maybe a bit more... if you wanted more power tho, you'd need to consider 2860-5 turbos or some GT-SS/GT-RS - theyre very similar, it all depends on what is more important, a high dyno number or drivability and response

Would have to disagree with the above, Before purchasing mine I weighed up all the options between the -7 and -5 set up's and eventually went for the -7(N1) turbo's and was extremely happy with the result. The car made 314rwkw and came on boost like they were still standard turbo's (absolutely no lag). -5's won't make alot more power maybe 30-40rwkw but they will definetly increase lag unless your planning on running aftermarket cams etc etc.

Haha Ryan logged in on the miss's account

The -5's come into there own on a forged rebuild people will easily get 400 out of them and if you talk stroker then what lag

[ISC-Performance]

^^^ yeah but going by his post he is looking at spending as little as possible.

If I understand it correctly the Garrett turbos relate to the following Nissan & HKS turbos:

2860-7 = Nissan R34 GTR N1 (although there are 3 different N1 models)

2860-9 = HKS GT-SS

2860-5 = HKS 2530

The HKS GT-RS are much bigger turbos and from what I have read on SAU you really need a stroker kit (JUN 2.7, HKS 2.8, OS Gikon 3.0) to avoid massive lag.

The following graph & chart may be a useful guide but are a few years old now.

+1 for -5's

b/c u'll have room to get bigger kw down the track with supporting mods

without the need to upgrade bigger turbos

from memory gt-ss = -7's
