Rolls Posted February 10, 2011 Share Posted February 10, 2011 Dyno's don't read time, they read rpm vs power (or variants of that). You can see the power under the curve, but you can't really tell the actual response time of the setup. Good point if you are locked into rpm. Surely you could set up the bottom axis as time though? I guess some of the old software is probably limiting but it would be a very simple calculation for the people who make it.

Nee-san Posted April 23, 2011 Share Posted April 23, 2011 oh, yes those pics on RHD are the correct HKS front pipes. one thing to note, they are quoting ID as 70mmX2 and single 85mm. most other places seem to quote OD which makes these approx 75mm X2 and 90mm single when comparing to other exhausts. I'll still measure mine this weekend, but those are the ones. best front pipes I've ever seen. have flex joint, have very, very nice welding, flanges welded on the inside, good quality stainless, extra thick flanges to help stop distortion and etc etc. they are the goods. Baron, Just bought a set of front pipes (possibly Top secret drag) They are 75mm ID into over 100mm ID merge, Coupling this with a pair of Midori Dumps, would this not be a better front front half for a GT-R ?

N1GTR Posted April 23, 2011 Share Posted April 23, 2011 What an interesting time for this thread to get bumped to the top, only a couple of days before someone is doing -5's on a stroker motor.

That is all. haha paul - were u really that impressed with my rb2630 i now have an rb26 & i personally wouldn't do another rb2630, the car becomes a 'chop shop' & besides that, rb26 revs much nicer & howls when compared to the 3ltr i also think though, either stick with the rb26 OR if u want larger displacement go straight to a 3ltr or larger Link to comment https://www.sau.com.au/forums/topic/349467-5s-vs-rss-on-a-larger-then-stock-motor/page/10/#findComment-5780389 Share on other sites More sharing options...

After driving your car (and I have since driven Steveo's) you would be silly NOT to go that way. They rev, they do everything a 26 based block does... just better. You only have to butcher the car if you have a 32... the other two is no real issue. I will say this though... if you have the engine out and WANT to keep the original block you have rocks in your head by staying the standard stroke crank. 77.7 mm at the very minimum. It makes the car so much nicer to drive!

Nee-san Posted April 26, 2011 Share Posted April 26, 2011 Something I do notice is that not alot of people take advantage of the 26 bore stroke ratio, so realistically for alot of people going the 3.0 litre for lazier power is indeed a good option, particularly if you are beginning a rebuild. There are lots and lots of very fast 2.6 litre cars though, some of the fastest in the world even.
