Lots of random questions

What is a velocity stack?

Would the gains be worth the cost of hard pipes for the intake as opposed to the factory plastic ones?

What Is the difference between a manual boost controller and an electronic boost controller

If I bought downpipes, cats, and a cat back exhaust would that be all of the parts I would need for a complete exhaust system? What about the additional pipes associated with the turbos?

I looked on z1 for zemmulater. I couldn't find it. Am I just blind or is there somewhere else u can purchase it? For somewhat of a beginner, would zemmulatr be worth the cost of being able to do the tuning yourself? Or should I just leave it alone so I don't mess anything up? I want th best power and economic gains possible from a chip. What is best?

I would like some Tein coilovers. The need to be able to lower the car a lot, and I would like them to have camber that I can adjust from a controller in the cab. Any ideas? The tein web site isn't very helpful.

I have found some rims that I absolutely love. I want to put 19 x 7.5 on the front, 20 x 9.5 on the rear with a tire sidewall of 25 or 30. When my project is done I want to be making 550 rwhp. Will wider or narrower tires be beneficial ? Would 19's on the front affect handling at all? Any other helpful comments about this subject?

wow, lets see
a velocity stack is a sort of air horn that allows velocity to draw in more air than it would otherwise, but has no practical or useful application in the z32

hardpipes, just depends, I opted for the silicoln hoses as they are a lto easier to get on an off

a manual boost controller is a bleed off valve you adjust it by trial and error, an electronic boost controoler is electronic and precise but a lot more money

depends on what you want, most people just get the cat back exhaust, the other exhaust mods offer little for the money, on the case fo a turbo car the downpipes can sive some weight as well as pita factor
, but if you have emissions testing you need to keep all the cats

not sure what tuning z1 se;lls but zeumlator, romulator, nistune etc will get you results on google, but for a beginner I'd skip it, the romulators are for tuning every possible bit in conjunction with a dyno wideband and knock detection, not for beginners

no, remote adjustable coil overs only adjust shock valving, not ride height not camber just dampening, not worth the money imho, and won't do what you think it does

bigger wheels are not uncommon, they gernally add weight and have no real benefit, the wider rears might help a bit with straight line traction, and the sidewall si an aspect ratio, that number means nothing without the width, and having 19's ont he frotn will make it feel harder and you are more likley to bend a wheel on a pot hole or get tht twitchy feel in a rut in the road

Why wouldn't jwt or pop charger intakes make a difference on a z32?

Would it make a differenc in performance depending on what material u use or intake pipes.

What things could I do to the car or weight reduction? I don want to buy any parts, just take out what's not needed. Any ideas an projected weight savings would be useful.

Also, when just looking through the car (it is the 2 seater model) under neath the panel just behind the driver seat (left hand drive) the one that covers the rear strut was a little plastic molding holding 4 ppastic parts. Any clues as to what the heck these are?

It does make a difference, not a HUGE difference but it's better than the stock filters.

No, who cares. As long as theres no leaks and the air gets to the throttle bodies, ur good.

Not much to do weight wise. If you're on a tight budget you could... Paint your rims instead of buying new ones, EGR delete (30 bucks), Adjust the timing (wouldn't recomend), fuel additives, pop charge, new spark plugs, new filters (oil and fuel). If you really want to save weight you could take out the back seats (if you have them), take out cruise control (whole system), take out AC (whole system), strip the rest of the car, and/or run it open cats to save weight on the back end.

Head light alignment tools. Useless. Most dealerships don't know how to use them. I have them too, but i took them out of the car and they're sitting in my basement. I don't really understand them but what ever.

I never addressed the cone filters, yes they will make a few hp, just a few

pipe material, well metal heatsoaks so in theory the stock or silicoln hoses will keep the intake charge cooler, on a boosted application the hardpipes allow for less flex and pressure drop, so yes material matters just not much

weight reduction, search for honads thread, he wrote the book on weightloss in a z32

for someone not wanting to add any parts you sure ask about a lot of them? and you aren't gonna make 550 whp without adding lots of parts

remember askign about 19 and 20 wheels? they are heavy and will make your car slower, there si a reason you don't see top fuel dragsters on dubs
