This book is now out-of-print.... rare book

21st CENTURY PERFORMANCE is the first high-performance book that covers current automotive technology - and how to modify it for best results.

There's a chapter on how the factory electronic engine-management and EFI systems work, and another on how to make changes to them. Did you know that some brilliant engine-management modifications can be done for almost zero cost? There's the latest in programmable management systems, including hard-to-find fitting and tuning information.

21st Century Performance sorts the fact from fiction on mufflers, catalytic converters and even complete exhausts. The difference in flow of press and mandrel bends, what back-pressure does for performance, which mufflers are noisy and which are restrictive - the best advice is here, supported by detailed test results.

There's a chapter on getting the most from the intake system, from simple but effective air box modifications, right through to designing a new tong-runner dual-length intake manifold. The performance of different air filters, the power gains from modifying intake ducts - it's all included.

How to modify the latest engines - including multi-valve and multi-cam designs - is discussed. Forced induction is covered in detail, with both turbos and superchargers extensively featured. There are also major chapters on intercooling and water injection systems. Boosting the power of a factory turbo car is discussed in step-by-step detail - even how to build two different turbo boost control systems!

And the best thing is that many of the modifications are of the practical, do-it-yourself type, giving proven power gains without breaking the bank. There are numerous results of tests carried out on modified cars - dyno graphs, flow bench tests ~1id on-road performance figures. In fact, there's also a whole chapter on how to test your own car so you can be sure you're always heading in the right performance direction.

If you want to go around corners as well as in a straight line, the upgrading of brakes, suspension, wheels and tires is covered in detail. And because 21st Century PERFORMANCE covers the latest technology, high-power turbo four- wheel-drive cars and active torque split control systems aren't left out. Uniquely, there's also a major chapter on making effective aerodynamic modifications.

And if you simply want to know how the latest in car technology works - from variable flow exhausts to computerised dyno testing, from all-alloy 32-valve V8s to twin sequential turbo engines - 21st Century PERFORMANCE will bring you right up to speed.

i think you gotta lower the price or something if your really keen on selling,

Its an outta print book... but more interested to selling to people who have been looking for it, than people who want it for cheap...

I can vouch for this book, its a very interesting read and is very hard to find, especially in Australia.

Good luck with the sale :(

Thanks mate... wouldn't happen to want another one by any chance? :thumbsup:

    • Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters. 
    • I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix. 
    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
