[turbo 280]

I was recently was spanked by a civic si. I am not a racer but to get spanked by
a high schooler....... hurt my pride. I am know on a mission for speed.

What kind of 0-60 times - if I do these mods on my 83zxt t-tops loaded.

1. intercooler hks, starion, npr any suggestions?
2. increase boost to approx 12 psi, protech-b electronic boost controller
3. blow off valve..any suggesstions?
4. clutch mods... any suggestions?
5. any other recommendations?

If I made these mods could I beat the civic, stock mustangs, eclipse..

Thanks,
Joel

taller gear like 3.90 or 4.11. honda's are 4.11 I think

the best thing you can do is get rid of your stock header and exhaust and get a MSA header, remove your catalytic converter (i didn't say that) and get a free flowing muffler with a 2 1/2 inch exhaust then add cold air induction and a rising rate fuel pressure regulator. And when are you gonna get that saggy rear end done? Replace those old struts and springs and stand proud!

Wow an SI took you out?

I'm surprised as to this day I haven't found an SI that I could not beat. Your on the right track as far as intercooler goes. If you want to do it cheap...I would look into a manual boost controller from Dawes Devices...www.dawesdevices.com for $50.00. Get a boost gauge from ebay $50.00. Do the pop-off valve mod http://home.flash.net/~joeao/greg/adjpopoff.html (some change), get a rising rate fuel pressure regulator and a air flow meter to monitor your fuel (35-50 bones for the gauge). You could safely turn up the boost to 10psi without an intercooler...just watch out for pinging. Once you get your intercooler hooked up, you could turn it up to 12 then you need to look into a programable fuel management system like SDS to go any higher (could be wrong though). You could also look into a blow off valve from a 1st gen talon or DSM...works great! At 10 psi, you won't have any problems taking a Honda out....I do it at 7psi all the time. Happy safe boosting

if you really want to beat an si . and your car is turbo turn up the boost. if no intercooler add water injection.my personal favorite is nitrous . go to http://photos.yahoo.com/sss510six for pics of port nitrous on my manifold.you do realise that there are several upgrades to the si and that the car could have been far from stock ie supercharger, nitrous, turbo ect.

Re: Wow an SI took you out?

So I'm assuming you have a Turbo 83.
Well FIRST make sure your car is tuned.
A bone stock Z that's near factory condition (atleast mechanically) should be able to beat a bonestock Civic (even Si).

Do you have a five speed?

In anycase... dont worry too much, you dont know what he was running.
He was probably spraying.. almost all the kids are now (**** Fast and the Furious)

but first step in mods is usually intake and exaust so start with that.
Then ignition.
then fuel delivery.
and your prolly gonna wanna dbl chk your gaskets before you start boosting.

I dont know too much, but I know you cant start boosting with out making sure you getting enough fuel and air.

And hey.
if you want to just do it the quick and easy way just start spraying NOS.
I wouldn't...
but hey screw it.

I have a truly insane friend that I have lost touch with but see him once a year at the Miami Ham Show. He happens to be the finest electrical engineer I have seen in my life.
I’m an engineer as well and when we get together ideas start flowing. He has me by at least 25 points of IQ so I really enjoy our interactions. Well back on subject, since he is an accomplished RF engineer as well as a person that loves beating the system he has made 100s of fringe devices one device that with a flick of a switch would transmit analog as well as pulsed digital noise with a moderate amount of power on the same frequency as the old 5.0s computers microprocessor. All he did was sit in his RX-7 flip a switch and stall out any mustang. I look forward to see him again, but like always he has some crazy project he is involved in and after we talk craziness we go on with our life till the next year. If you had some bucks maybe you could have him sit still for a week and make from scratch a multi band disrupter. His code name in the underground electronic world is Mike Maniac. Nice guy and tons of fun.

[280 ZX]

???

this must have been a hot rod Civic. My '82 280 ZX non-turbo 5 speed put a whoopin' on a stock Hon-dog. Also, no need to deal with the rear end, if it sags when you dump the clutch off the line or while your're going, it puts all the power straight to the ground for more traction, and it looks cool!!

More tips

Actually you should get the soggy rear fixed because the torque that could be going to your wheels is now being absorbed by the spring/struts as they compress. Stiffen it up and you'll get some perk back. There is just so much you can do with a turbo. Exhaust is very important. Go no less then full 2.5" and don't use a big chambered muffler as they add backpressure (bad on turbo). K&N cone filter in place of the big blue box will help. Intercooler will let you run 12-14psi. Any more then 14 is useless without upgrades to the turbo. If you don't want the IC route then don't go past 10psi on high grade gas. It will also help to get a grade cooler spark plug when raising boost significantly. Get a boost referenced FPR if you're shooting for 10+ psi. A BOV (1g DSM vehicle works nice I hear) will help between shifts and extend the life of the turbo. After all that, you may then consider ignition upgrade to a multispark like the MSD 6al or Jacobs or whatever you choose. I'll let you in on a small hint for a $3 boost controller. Get a 3 way 1/4" vac hose T fitting and put it between the wastegate actuator hose. With the 1/4" open T this will let you run about 10-11 psi. If you put ~3" long hose on the open end of the T and by using a small hose clamp on the end, you can control the boost pressure by compressing or decompressing the hose. Simple yet effective.

3000 lbs, only 185 HP. You NEED to +boost

You will WIPE up Hondas and most others out there by very simply intercooling your ZXT with one of many capabel intercoolers out there. You can easily turn up your boost to 12 pounds although I run up to 14 with no problems. I also run a 3" exhaust straight back to a Dynomax super turbo muffler. You probably can't eliminate the cat on your car if you are concerned about passing inspection. Also, the rising rate fuel pressure regulator is an easy add on that will help as well.

Now, my 240 with ZXT engine in it is much lighter than your car so I am beating EVERYTHING out there except the occasional Viper. But you should definitely piss on Ricers and Mustangs just by intercooling your engine and getting that boost up there. Try to free flow your exhaust as much as you legally can.

AND remember, you have a Luxury car there. It is a quiet, comfortable, air conditioned, heavy riding car. If that's the kind of car you want, you have to expect crude lightweights like the Mustang and Civics to give you a run for your money. If you want to kick some serious ass, you have to stick that ZXT motor in a light 240Z. But be aware, you will scare yourself, and goodbye ZXT comfort; Hello loud, snarling,feel-every-ripple, no-air, cabin-fumes, vicous beast!

Re: 3000 lbs, only 185 HP. You NEED to +boost

HEY!!! I have a 1971 240Z....I am restoring it. I am wanting to put in a 280Z Turbo engine in it. That or a ford 302 with a 5 speed trans. I have both the Turbo engine and the 302 and 5 speed. I was leaning toward the V8 thing....but I could use it in another car. So this takes mebake to putting in the Turbo engine. Can anyone give me some hints and tips on how to start this, the best way to do it....and on the cheap side. I do not have tons of money right now. I have gathered MANY Z car parts. I have several engines and trans. I have a 3.9 R200 rear end. A 81 or 82 non turbo 5 speed trans. and a 82 or 83 turbo engine...not for sure on the year. I need to get the wiring and computer out of a turbo car. I heard that 83 is the best year. Will it hook up to an 82 engine? Also, cn anyone give me some websites to look up? I found one a long time ago that had tons of tricks on upping the HP on these engines without spending alot of $$$. Any help at all would be a big help.....thanks!!! Also.....If anyone is in need of Z car parts ask. I have a MANY extra ones laying around and in good shape. 70 - 83. Thanks again.

Re: More tips

Read your tips with interest...what is wrong with the stock muffler/tail pipes on 82 Turbo? What do you recommend? As far as stiffening the rear end, what do you suggest? I, too, like the way that sucker "hunkers down", but if it causes a loss in performance, I want it fixed. Not much into modifications, but would like to improve my performance...
