i will be purchasing a 1992 300zx tt over the winter and im looking for cheap ways to up the pony's a little. i figure if i spend $50 on a water pump and run misting nozzles to the front of the intercoolers that i could get some gain. ive seen a 10 horse gain on a 500whp Z being dyno'd. im curious to see if it will make a noticable difference while driving or if it will be a waste of time.
Thanks!

 

Welcome to ZDriver!

Install an EBC... that will be a reliable hp increase.

 

That's alot of work and extra equipment for a measly 10whp, especially when there are so many easier and cheaper mods that yield such higher gains.

 

is there any relativly cheap, reliable boost controllers that you would recomend? and any mods for around $100?

 

Look into boost jets, do a tuneup and if you don't have a smog inspection, look into deletes.

 

Free mods, delete everything you can (assuming no smog) as hoov said.

Eliminate all the useless vacuum lines (twinturbo.info gives a good write up on them). EGR, AIV, PRVR (you will have to spend a small amount on the delete plugs). Ensuring you have no vacuum and boost leaks is the best thing you can do for a TT.

Then just start with the basics, intake, pulleys, exhaust.

The misting isn't really going to help much I wouldn't think until you start getting into dual pops and larger intake piping / TB's. That's when you really want to start doing intake air temps, but really you will be looking at larger turbos to handle the extra air etc and it will get expensive.

Your biggest gains will be seen from intake, pulleys, 3" exhaust (turbo back or if you can afford the Mike Smith manifolds), and ECU tuning. Once you start getting into ECU tuning, get a WIDEBAND AFR guage for your own peace of mind. Also remember, as you increase power, you will have to start looking at your clutch / flywheel setup to ensure it can handle the power (thus more money)

If your limited to $100, just get a JWT intake and the things to delete that bull crap.

I hate my Greddy Profec B Type II controller. It's a pain to set. There is one where you just set your desired boost and that's it, I can't remember which one though.

Also *EDIT* I would never run anything other than a Nissan water pump on my car... I've had too many issues being stranded on the highway because some *** hat put a doo doo water pump in my car before I bought it.

 

downpipes and pullies make a huge difference on a TT. if it's a stick a light weight flywheel and good unsprung clutch disc will make a world of difference in acceleration and clutch feel.

 

thanks fellas, i havent seen anything on the vacuum\EGR deletes on any other forums before, any idea of the gains? and by pulley's are you referring to an under drive pulley? or all the accessory pulley's too?
thanks for all the help!

 

LOVE the signature line!

 

Is the Mike Smith manifold the only worthwhile manifold upgrade? Pretty freaking expensive, it would be nice if that money could go into the rest of the exhaust/turbo set up. I'm leaning toward better spool up characteristics rather than extra high end power.

 

Ported stock manifolds are pretty good, not as good as say tubular or MSP manifolds though. Pulleys, bigger I/C piping, better flowing intercoolers, down pipes, Efan conversion, light flywheel and clutch, 60mm TB's, BB turbo's. These will all help with turbo spool up.

 

Thanks hoov.
