Serpandrew Posted November 2, 2012 Share Posted November 2, 2012 Have a read of this: http://www.skylinesaustralia.com/forums/topic/368988-tomei-arms-m7655-on-rb26/ Long story short: More expensive than the tried and tried again garrett bolt ons (comparison to -5's seems like mostly) except laggier.

Serpandrew Posted November 2, 2012 Share Posted November 2, 2012 (edited) How much power do you want and is this just for a street car? -7's might be a bit too small, they are the standard bnr34 n1 turbo. -9's would be better for an all rounder and still a decent upgrade. -9's don't come with actuators standard though so you'd need to grab some with them, also a couple of the coolant fittings don't fit without modification so you can buy ones that fit for ~$70 extra.

OIR32 Posted November 2, 2012 Author Share Posted November 2, 2012 and while we are on turbos, how about TDO5-16G greddy ??? what size are they? and any good?

Serpandrew Posted November 2, 2012 Share Posted November 2, 2012 Why do you want to divert from turbos that have been tested and given good results multiple times to turbos you don't know anything about? If it's a street car just get -9s and be done with it, almost everyone else will say the same thing Link to comment https://www.sau.com.au/forums/topic/412918-tomei-arms-m7655/#findComment-6607071 Share on other sites More sharing options...

Serpandrew Posted November 2, 2012 Share Posted November 2, 2012 (edited) No worries, you should have a read of the following thread btw: http://www.skylinesa...rett-gt2860-9s/ Has heaps of examples, tells you everything you need to know about these turbos and other similar options and why you shouldn't go for other turbos. Yes it's a long thread, but you'll be fully educated and won't have second thoughts after buying them Edited November 2, 2012 by Serpandrew Link to comment https://www.sau.com.au/forums/topic/412918-tomei-arms-m7655/#findComment-6607083 Share on other sites More sharing options...

OIR32 Posted November 2, 2012 Author Share Posted November 2, 2012 so i seen alot of 5's 7's and 9's, what are stock gtr32 turbos? and are 5's heaps smaller than 9's? alot of people recommend the 9's which sounds good to me aslong as the lag isnt to much?

scotty nm35 Posted November 2, 2012 Share Posted November 2, 2012 The -9's are smaller and the most responsive of the lot. Better read the thread above and check the dyno results thread also.

Serpandrew Posted November 2, 2012 Share Posted November 2, 2012 (edited) -5's are a bigger turbo, -7's are the smallest (~270-300atw?), then -9s a bit bigger (~310-330atw?), then -5s (~350-400atw) which will be laggy on a 2.6 and no good for street driving. Don't quote me on the figures those are just estimates, for them you of course need all of the supporting mods. Have a read of that thread I linked you and it will answer all of your questions. Stock turbos on any gtr (except the n1's) have ceramic wheels which can't take much boost, and they are fairly small anyway. All of the above are steel wheel and bigger turbos, they can take a fair amount of boost. Just keep in mind that your engine is around or possibly even over 20 years old along with the turbos, those things have had a long life and you'd need to replace a lot to get a reliable and powerful result.
