well although made the decision that a turbo will be my next mod, i need your help in choosing which one. i am still in college and this car is my daily drive right now so my question is, which turbo system has good qualities in performance, drivability, and reliability?

i have the crawford headers and want to keep them, i know with the turbonetics kit you can keep your manifolds, but how reliable is that kit? i wont be boosting high- very conservative with nothing higher than 7psi and actually want to keep it between 5.5 -7psi.

money is somewhat a factor in what i decide to get. meaning i want a system that doesnt require a whole bunch more parts to buy to get it to work. so whatever system you think is best, what else will i need to get it running perfectly (bov, boost controller, oil catch pan, ect.)?

thanks guys! im sure ill have more questions but thats all my little, tiny, brain can conjure up at the moment.

Well you already mentioned it...Turbonetics. Good price, complete kit, no issues on my or their Z to date. Their Z has had that kit for about a year now.

 

yeh? very nice. yes, i think this is the kit but i still would like to hear more from others about other kits and their opinions. however, what may win me over to turbonetics is that i can keep my crawford headers. from what ive seen on a friend's s2000, he made good numbers by just fabricating his own equal length header.

turbonetics is around 4700-4800 i believe... and you lose your cats, and I believe that AAM is saying around 850 for install until they have installed a few and figure out how easy it is to install. I am pretty much the same boat as you being a college student. If there isnt engines blowing up left and rite with the turbonetics kit, I believe its going to end up being the way to go. Another thing.... you live in florida so being catless doesnt affect you. OH yes.... and they have a warranty. How nice is that?

 

WHOA!

warranty????? wtf???? can you elaborate on this? this might be the turning point where i actually make a decison to buy there kit before i have the money and before i hear any other opinions. btw: what type of numbers are being seen with this kit? psi? i would install this kit myself, its a peice of cake (i think, therefore i can)i only say that because i have done everything on my Z, s2000 and TT supra. my s2000 was very hard with the comptech SC only because i had to tip the motor to install the exedy clutch/fly. if i had done that at a different time than install it at the same time, id prob. find it was easier.

john

 

Turbonetics gives you a 12 month 12,000 mile warranty on the entire kit no fault no hassle. If any piece of the kit breaks regardless how Turbonetics replaces it no questions asked...

Power is 386 RWHP at 8 PSI 11:1 AFR

 

internals? how long have you been running with that kit? how do you drive?

aside from the turbo kit itself whats else did u add? (boost controller, gauges, ect.)

john

 

The longest running Turbonetics kit car is their Z. It has the stock bottom end and has been running for close to a year... And trust me when I tell you they have FLOGGED THE **** OUT OF IT!

 

True...just note...if it wasnt obvious already...that the warranty covers the kit only, and not any physical damage done to the engine. If you damage your engine, or throw a rod...you are on your own.

 

it was obvious btw love your car!

I would say u go with APS. its a little bit more expensive than any other kit but its the most complete one.

 

ok, see this is what i need to know also.

can you explain HOW complete the APS kit is? now, what is the difference in completeness between the turbonetics kit and the APS kit? reliability is a MUST, so how is the APS on reliability?

thanks,

john

 

ok another question-

this concerns MIAPLAYA and fernandito7:

i see both you sigs and MIAPLAYA i noticed that your whp, although higher, is lower in comparison to boost between you and fernandito7- why? Even tho your at 8psi and him 5 (or 5.5 is stock greddy boost), he is just about 30 -/+ whp less than you. on my supra adding three psi made a pretty significant increase in hp. MIAPLAYA: is your dyno numbers a result of you Z with ONLY the turbo on it or with exhuast also? frenandito7: was your dyno number a result of tuning as well? or just the turbo and other mods you have? MIAPLAYA: does the turbonetics kit come with a preprogramed piggyback or ECU? have you done tuning to yours? what is stock boost on the Turbonetics kit?

ok sorry for the million questions. just i need to know some more before i buy a kit.

thanks,

john

 

The Turbonetics is IMHO just as complete a kit. The Turbonetics kit uses a reflashed ECU to tune. My car made 386 RWHP at 8 PSI and 11:1 AFR with only engine mods being the turbo kit and exhaust.

 

okay im pretty sure this is the right answer -

the small difference in hp relative to the difference in boost is a result of the greddy kit being a twin turbo kit and the turbonetics being a single turbo kit. that means the air flow for both kits at a certain psi is not necessarily equal. and i suppose the same would be true of different tt kits or different s/t kits using different size turbos.

or it could be a result of the tuning for both kits.

either way, someone please correct me if i'm wrong.

 

how do you figure? ever tho the twin is moving more air, the twin can still only shove so much into the intake tube down into the engine. same is true for the single. what i am think now may be the case is efficentcy (i suck at spelling). the twin seems to be more efficent than the single. this would then lead me to beleive that with the turbonetics kit and simple swap to a big turbo or compressor houseing and wheel would lead to and increase in HP without touching the boost.

i could be wrong however.

is stock boost 8psi? do they reflash the oem ecu ?

thanks
john

 

Yes stock boost is 8 PSI and they do reflash the your stock ECU..

 

i just think that the aps is more complete because it comes with an upgraded fuel pump, new fuel system return line or something like that...and the fact that i have not heard anyone having problems with this kit. I strongly believe that the unichip is way more superior than the emanage. My installer told me that the unichip is way user friendly than the emanage. Also no cutting into the Z's ecu as with the emanage. The unichip just clips on to the ecu's harness. Also i just think that APS really had more time to R&D their kit and fixed some problems that both greddy and PE had when they released thier kits.

 

If your going F/I make sure you have extra cash to pay for any problems that arise. Including the worst possible senario blown motor. Your car is a daily driver I would bet that most of the cars that are F/I arent actually daily drivers like your will be. They have alternate cars they can drive.

Also do you plan on getting any other car? You instant lose any mod money you put into the car, also being the car is F/I it will be a lot harder to sell. Just some thoughts.
