Hi Guys,

Like most of you I have read through the abundance of Greddy threads on here. I've read a lot that the Greddy kit is not good to deal with track temps. Kinda curious on some insight why? Is this simply an issue that could be solved with a good oil cooler, upgraded radiator, fan switch and thermostat, or is it far more complex beyond that?

Reason I ask, I intend on getting fairly religious with auto-x and tracking my S. I currently have 63k miles on the car, and plan on going Greddy around 70k.

I am interested in installing it myself, , and will go the full mile to have it professionally tuned properly and also plan on either getting the t1r 70mm (same as the greddy dp) or the Greddy Power Xtreme 80mm single exhaust along with wide band and the various guages I would need to monitor everything right, (egt's, Oil temps/ pressure, boost, etc.) In addition, I was planning on a koyo radiator, with j's Higher pressure cap, j's fan switch, j's lower temp thermostat and the Greddy oil cooler.

My goal is to get 301rwhp with as little boost and as safely as possible.

What issues have you guys with the kit encountered? Do I need a better intercooler/ piping? I planned on running the hks ssq bov, even though a bov is not said to be needed, however I feel to let the excess pressure out is always a plus on turbo wear.

LMK and thanks in advance.

That sums up what you need to get to track the car. You can't stick a turbo on a non-turbo car and expect the cooling system to be optimized for the increase in heat.

Consider venting your hood as well


Otherwise, the kit should be mean on the track. For autox, you probably don't have to worry about cooling so much.

 

Thanks spec, I planned on all those upgrades regardless, I kinda consider it part of the "turbo kit."

 

oh kinda off my own topic, if anyone would like to chime in on what clutch package they're running, and also if you've modded your diff at all that would be greatly appreciative!

 

Thats a good way to think about it

 

yo wut up J's im going for a ridiculous setup with built engine gt35r etc.

you learn alot in the FI section especially from spec ops.

If you want your diff to be able to take a beating you should either go with inline pro kit which is amazing or do what im doing which is the puddy diff from HTG which is cheaper and said to be able to take launches at 600 whp.

also i dont know the reliability out of the turbo manifold greddy gives you. im going with the inline pro mani b.c i know no one has ever cracked it.

 

I was thinking of a puddymod diff also, and as far as the header, greddy supplies it and warranties it so if it cracks they can send me a new one!!

 

yeah i've read it many times here--that people think the greddy kit cannot handle the track, but i've never seen anyone actually post this. What i have seen is that most people (mainly in the competition forum), don't like to take a turbo s2k (any turbo brand) to the track due to the increased issues with heat and extra strain on the motor & components. There's nothing about it that makes it worse for track duty than any other kit. Only thing i can think of is that it's oil cooled, so an oil cooler would most probably have to be on the list of parts to get. If anything, it as more 'heat-blocking' parts than some other kits i've seen:
*air diversion plate to block hot radiator air from the intake
*long intake arm, relocates the filter away from the turbo
*retains some of the stock exhaust manifold heat shield (as opposed to none)

 

Thanks Chris, I kind of was not getting at just the Greddy kit persay, however turbo s' in general. My whole point of turbo'ing my car is of course the fun factor, but also to be faster in competition. Now I know i just opened up to beeing reemed by the "you don't need to mod your car you need to learn to be a better driver" growd, and I am a whole hearted believer of that. As as such I revert to my MAIN reason for turbo'ing; the extra fun, push you into the seat factor. I'm just looking for a little more hp than a tuned n/a is capable of (without going 2.7 stroker of course): my goal being 301hp as safely as possible. I truthfully see myself auto-x'ing a lot more than track time in the near future, however I just want to be sure that when I do venture towards track time, allbeit only probably a few times a year (3-4), that something is not going to blow up due to something that I could do some preventative changes before hand i.e better cooling mods, gauges to monitor stuff before it blows so I know to STOP etc..... hope that makes sense

 

I think an oil cooler POST turbo wouldn't be a bad idea if theres a nice way to set that up.


However I strongly disagree with everyone being against turbo cars on the track. I fully intend to make a track car out of mine. I've had turbo cars prelude,ZX TT in the past and never had issues with either on the track. I think the koyo radiator upgrade on it's own would be the end to any problems you MIGHT have had. The other good mod is a baffle for the oil. That's a concern more on track then AutoX though since AutoX doesn't have extended periods of high G corners in one direction. I in general am against turbo for AutoX since it is constant on off power applied, it exaggerates what a turbo car does worst. Not to say it can't be used correctly but it makes it MUCH more demanding to get the most out of the c ar. I wouldn't be surprised to see most drivers do better in auto-X by short shifting quite a bit in a turbo car.
