JWT TT Vs Greddy Seen Both Heres My Assessment
I saw my first greddy kit today, although not installed. After a little debating I will be WAITING for the JWT. for the following reasons.(ive seen both kits although the JWT was on a G35)
1. The oil return for the turbos returns the oil under the pan hence since gravity is the force returning the oil under the oil pan line turbos can easily be clogged and damaged. Where as the JWT uses a billet spacer between the block and pan with J style tubes that return the oil from the turbos above the oil line. I know it sounds petty but if you pay attention to little details your going to pay attention to big details- I.E the turbos.
2. The JWT uses Ball bearing turbos good for up to 530hp(internal
mods) whereas the greddy are not BB and good for up to 400.more over the quality is just better plain and simple.
3.The air intake on the greddy uses 2 filters one on the factory side and one on the passenger side(from what I seen in the pics I dont see a sufficient amount of airflow on the passenger side) someone correct me if im wrong?Whereas the JWT uses 1 popcharger in the stock location connection both turbo inlets together.( I thought it was well thought out)
4. I think the JWT is more of a system you would find If nissan would of made the car with a factory OEM quality system( that great) whereas the Greddy is pretty feasible but yet rushed( remember its my opion)
5. I do like the fact the greddy comes with more injectors
AS far as being 50 state legal I live in CA (very stict) JWT is wating for carb as far as I know. I am still contemplating the Vortech SC, but most likely WILL wait for the JWT unless the FI bug fever gets Worse. And while I have yet to see the other systems on the market I hope to soon. But it seems JWT doesnt put anything out there thats not 100% thought out. If im wrong about anything please correct me .. this is what the hobby is about helping each other make good choices when spending our hard earned cash -BigErn

Dude,
I hate to sound like a jerk, and I've got enough strikes to back it... by why are you so stuck up JWTs ***????
All you post is about JWT this, and JWT that...
We talk to Wolf on a weekly basis... his kit is NO WHERE'S NEAR being done. End of summer at EARLIEST. Even he comments some of the other kits are VERY nice. He will just be offering another one to the community.
Chill man.

btw... for s***s and giggles we called Wolf.
The plenum is a "just for fun gig" for turbo cars only. NOTHING he is planning on mass producing.
So until you come up with more "hard info", I will continue to enjoy your fountain of mis-information.

Honestly, i don't think this makes a bit of difference. That oil is sloshing around big-time inside that pan. The crank sits right above it, and I suspect it makes no difference if it whether it drives a few inches higher up.
2. The JWT uses Ball bearing turbos good for up to 530hp(internal
mods) whereas the greddy are not BB and good for up to 400.more over the quality is just better plain and simple.
This is an absolutely false statement. The Greddy turbos, although conventional, are highly reliable and have been testing over 100,000miles. They reach their peak efficiency in the 600whp range. Greddy designs their turbo's to be in the bottom end of the efficiency island, to allow for future mods. In fact, at 6psi, the turbo is really under-utilized.
3.The air intake on the greddy uses 2 filters one on the factory side and one on the passenger side(from what I seen in the pics I dont see a sufficient amount of airflow on the passenger side) someone correct me if im wrong?Whereas the JWT uses 1 popcharger in the stock location connection both turbo inlets together.( I thought it was well thought out)
You have a decent point here...and I tend to agree with it. However, with forced induction, since the air is being "sucked" into the compressor and then shoved into the engine, atmospheric airflow is not as critical as it would be with an N/A car. I am not too concerned with this.
4. I think the JWT is more of a system you would find If nissan would of made the car with a factory OEM quality system( that great) whereas the Greddy is pretty feasible but yet rushed( remember its my opion)
Greddy spent over a year designing the kit. In my opinion, none of the various TT kits are perfect...each has their pros and cons.

Me too!

Greddy will have CARB exemption by the summertime...they have already applied for it, and designed the kit to pass. Most of their other bolt on kits have CARB exemptions.

Oh my god...I cannot even believe that you'd post about someone being up someones A$$.
Pot..... meet kettle.
Every post I see from you has something to do with Crawford and their products. You even post in threads about other manufacturers products with your Crawford propoganda.
You should check your backyard before walking all up in someone elses.

Come on out, we can go enjoy a wine tasting event... and live jazz... You have got the WRONG idea. My mistake... Cali is the land of gods right?
Very ignorant of you let me point out.
Even then, who said you called anything a POS?
Recommendation... might want to check your oil.

Point 2......where did you get these numbers ?
The Greddy turbos are good for 400+ hp each....far more than the JWT turbos are capable of.
What are your statements based on that the JWT turbos are far superior ?

From what I'm understand the JWTs are going to have even LESS lag. Smaller turbines = WAY faster spool.
Nice advantage to the competition... mentioning 530 as its "Sweet spot" would lead me to believe their going to have to boost just shy of 1BAR.
The mitsu turbos sweet spot is nearing 20psi, far north of 1BAR.
So I'm open to comment bigern1970, why ARE the choice of turbo JWT is using "superior"?

I think that JWT meant that his are good for 530fwhp.....that is his standard practice for turbo upgrades, naming them after their rated fwhp.
The greddy turbos are definitely good for 400hp each....I know guys that are running the smaller version of this turbo the TD05-16g and hitting well over 650 rwhp. These turbos are definitely capable of well over 750rwhp
