A lot of people have them, no doubt. It's all in the setup though.

not forgetting when Justin's results and opinions were made... majority of higher powered -5 turboed GT-R's are only coming around in the last couple of years. and even still now, most only get mid to high 300's...

Big dollar and R&D projects always get better results.

No doubt. A mate in 05 had a -5, standard engines GTR making 300. That was considered a half decent result. Now it would be considered a joke. Setups, fuel, ECU's, exhaust sizes (a 3 inch IS NOT BIG ENOUGH) and possibly tuning methods have come along way!

I had trust T517z 10cms on my old engine/setup, completely stock engine made 370kw at 24psi, then popped a head gasket lol

Was laggy but when they came on Hang on !!

That setup has been sold, engines been forged and running a 6266 getting tuned on Friday, keen for results !

The whole 'lethargic, but when it comes on.... HOLD ON' thing... Isn't that just turbos making the power they should, but being a nugget through the mid range?

Cars, power, times and not least, everyday performance all depend almost entirely on the seven P's. perfect prior planning prevents piss poor performance. I have used 5's on a dead stock 26. Wasn't particularly blown away. Buuuuut, when I started building and improving, they really started to shine. Would I have 5's again? You bet. Would I build a different way? You bet. For today's fuel quality and cost of performance parts for 26's, you'd be mad to not build a tough 26 and run it on Jew brew AND still look like a stock engine bay that can peel your eyelids off when you give it the nuts, because let's face it, the police these days are getting smarter, and the bullshart fines are also getting worse.

I've personally built big power 8's and after looking at graphs and seat of the pants, for a stock as ya nannas undies look with big block torque, can't really go past a 2.8 with a well sorted set of 5's and Jew brew.

he he he...

The garretts are a pretty good choice....

I ran my T517Z's 7 years ago- they were the best option for me at the time. No graph.

They may out perform on a dyno... but it's hard to argue with 138mph in a full weight r32. havn't seen many -5 cars run those sort of numbers on a stock motor in full trim?

I don't like -5's the same as I don't like 'itard- Apple' products....

Wasnt nitrous used when you ran 138mph?

Not really... the torque delivery, it's the way torque not the power multiplies and gives you that rush.

Wasnt nitrous used when you ran 138mph?

Yeah, I was shooting a very fatt 50hp (read, probably 25hp gain) shot to get me off the line. As much as anything it provided a consistent intake temp thus more consistent times between day and night. Call it 2mph at best.

Ok cool. No lag + nitrous = crazy

There is still lagg.... but your launching well within the torque curve.

There is no massive push from that sort of nitrous. It's more like driving on a cold day v's a hot day.

Nitrous is one of the most over rated yet least understood power 'adder'.

Funny how the same setup work for some and not for others

I had everything like you minus cams (but with cam gears ) and could only manage 370kw

That's with HPI 3" dumps, custom twin 3" into 3.5" front pipe, custom 3.5" cat back, arc front mount, etc etc !

stock head... drop in 260deg cams.

bone stock 15yo engine

bolt on turbo's, dumps, cooler/pipe work, rb20 afm's, PFC, fuel system on 98.

Wow minimal mods nice work. What was you mph off nitrous?

Edited by Ryan1200

NOS was the number one mod in the fast and furious movie, yet 12 years later and its the least used mod, it's pretty amazing that hardly anyone uses it. I think E85 and billet turbos outperforms it by far interms of reliability and price.

^This 34 made 842rwkw with Nos and 963rwkw without ..lol

I just bought a car yesterday with 10cm units fitted, will be interesting to see how I like them as my last Gtr had -5's. Justin you would know the car, silver, jun engine bits, built in Hobart......

Is that a stroker ? I would imagine these turbos to be perfectly suited to a 2.7/2.7L etc

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
