lmao fast and the furious spec yo havent you seen f&f??? they got a 10 second supra by just painting it orange, applying some stockers and putting some fully sick gauges in the car. lol but as simon has already stated
Only 3 gauges? You need vacume, boost (I know its an NA), fuel pressure, a MONSTER taco, fuel gage (more can't hurt), hell, put some guages in the rear of your head rests so your passangers can keep an eye on all your vitals too
Na man fast and the furious spec is now all digital with out of this world GPS's that have the track for street racing in them
I'm sorry but why would you put forgies in a N/A.. and another thing, its going to cost you heaps just to put them in , and you would get no benefits from it . let your builder sort it out for you . you bottom end may just need a freshening up .... spend that money on your heads ... if your going to pull it down anyway .. question , have you ever seen an N/A piston let go .. if so under what conditions ?????
was this directed at me? agree with it being pointless putting forgies in a na, kind of the point i was trying to make, agree with the headwork thing, worth doing on any motor you will see some gains regardless of motor type size etc..... are we talking z's only or in general..... na z pistons are known to fail in high boost tt aplications (obvious though) ive seen v8's and others lose compression etc through running excessively lean they are na's but different kettle of fish so to speak....
So what you guys are saying is if you were spending $10,000 plus on a performance NA rebuild you wouldn't spend $100US to $150US on upping your compression slightly with less reciprocating weight on a stronger piston that is NOS rated by the manufacturer ? The reason I would use this in an NA build is different to the reason why i would use it in a TT build, in a TT its primarily about detonation damage resistance under boost, just because we are talking about an NA it doesnt mean the positive attributes of the product disappear.
if i was building a performance na engine i would definately not use a standard na piston, i would oversize it as much as possible bore wise so as to increase overall engine capacity (even if its only a few mil) and thereby increasing power and torque exponentially..... in the same line of thinking, if i was to use a forged piston i would make sure it INCREASED my compression , not reduce compression that will cost you power and lots of it........ remeber forced induction motors need lower compression than a normally aspirated engine so they can handle increased load on the engine through big turbos/superchargers running lots of boost so to summarise, na engines high compression components and design, tt lower comp components
What I've spent on my NA would just about have bought me a TT engine to put in it! But I don't like the power delivery of the TT... nothing to start with then all Hell breaks loose some time later! Just get the NA to breath easier, (pod, headers, exhaust) and spin up quicker (UDP). If you have the spare bucks think about an ECU chip, but mostly concentrate on the brakes and suspension. A better clutch is a good mod for a manual NA. You are never going to get much more than 150rwKw from an NA unless you have MEGAbuck$ to spend ($15-20,000). And that's just getting to sad TT-type numbers.
I think there is a miss understanding here, when did anyone suggest a low compression NA ? Maybe have a read of posts again.
ok ive reread all posts dont get my wrong im not angry or trying to argue or be nasty, but my point is this......... if you build a engine to be a high performance na, then you will not be able to use forged pistons designed for a tt, as the piston is a component that is different in the na/tt, and one of the things that is different about it is the fact that the tt pistons lower the compression ratios to accept boost....... therefore, you would need to use a piston designed for the na, and ive never seen a vg30 forged piston set designed for use on a na engine.... thats my point, hope it makes sense..... please correct me in any way if i am incorrect
there is no reason for you to go with forgies .. you are so far away from needing them , is not funny .. do your heads up and a good set off headers and tune the thing.. im assuming you have pod, cat back, and a good clean engine to start with here is something to start with .... http://www.aus300zx.com/forum/showthread.php?t=288111 these will help out as well ......etc etc ......
It was previously covered in my 7:12am post. It details the availability of suitable NA forged pistons with compression ratios of 10.5:1 and 11:1 readily available and probably custom ratios from Z1.
righto then, i didnt check your links, my apologies...... so if he was doing a full on rebuild, yeah those na high comp pistons would /should go on the list......but the op is so far of that stage of performance at this stage its still f'n miles away from being necesarry for him lol!
Not sure on what TTs you've driven, but I'd say power delivery of a TT is pretty decent for a turbocharged car. Very quick turbo spoolup, more so if you have a complete exhaust system (turbo-back). Something like 6psi or so at 2500 rpm, definitely far from a laggy drive. Try a gtst Skyline for comparison, almost no boost until 3500-4000 rpm. -Kirill
In his 2:18am post he asked how much were "forgies" and i replied about $10,000 as part of rebuild. This was not suggesting he do a rebuild but explaining that with a $2000 budget, it was of the menu.
He does have it for sale, and has some spare cash to spend that's why I suggested to get a TT instead.
I agree with sandeep, however because we drive NA's we'll never get huge power. Your better off upgrading your handling characteristics first. coilover's, adjustable control arms, strut bars.
my advice is dont even bother. keep your 2k in savings for when something inevitably shits itself......its gonna happen
