That is me. I have read those articles and they are quite good. I was considering using a smaller turbo but I decided not to. Your right, the TO4 is big for this motor. My boost doesn't kickin until about 3700rpm.

More like a small trimTO4 will be boosting hard by 5000 rpm. With a 7000 rpm rev ceiling this is pretty pathetic, less than a 2000 rpm powerband. If 400 hp is your goal, why do it with an old big heavy wheeled and inefficient turbo when you could do it with a smaller faster spooling turbo, one that will really spool by 3500 rpm? Even a properly matched T3/T4 hybird would do much better here.
The TO4 is a very bad match for this engine. Do your homework.

I completely agree. If I were you id opt for a T3 family GT series turbo, IE gt30r. A t4 turbo would have way too much lag for the 1.6.
A T04, I presume is way too big for a GA16 unless you want boost at an RPM where you don't have much of a range before the fuel cut. I suggest you read the turbo sizing articles in NPM where you can determine what size turbo to use for your needs in the line of what wll really work.
You can get 400 whp using much smaller turbos than that. Or are you the guy whose Hp and Torque doesnt meet at 5250rpm?

Granted we have always said and known that T04 is not the proper turbo for a GA16, I guess to each his own.

damn, you guys are kinda relentless....i wouldnt wanna do anything to my car that you wouldnt agree with...

Well, I totaled my B14, so now I have a Eclipse GT. I'm just longing to get back to Nissan...
def man, the t-25 and the t-28 are perfect turbos for the GA, they spool quickly, and hold a decent amount of boost. a t-28 (not sure about disco potato) will hold roughly 340whp with the right fuel mods.

A lot of research,time,and testing was put into finding out these things. When others come in and make statements that are based on zero testing or have zero data to back up claims it tends to rub people that have put in the time the wrong way .. We simply don't want others to have to go down the wrong road with something that isn't going to be a very good setup for this platform.
I'm all for people being original... but without test data it's speculation.. I wouldnt think many would really want to spend the sort of money needed to create a decent turbo car on speculation advice.
Plenty of people from Garret, JWT, and automotive engineers have all agreed the T28 and T28 "Disco Potato" are the optimal turbos for the GA16. It amazes me that anyone would even question this at this point...
maybe i dont know the whole story...but, if thats the turbo he wants to use...thats the one he wants to use...
i wouldnt get it...but to each his own
There really isn't a story... the math and tests have shown the T28 as the best choice..When the makers of the turbos agree it's hard to argue the point.
I agree with you 100%, He could put a 747 engine on the roof for all I care..haha... Just as long as others know it's not the optimal setup for the GA..
He could put a 747 engine on the roof for all I care
HEHEHE LOL
but back to the evil twin, now wes, i understand that you use a progress lower control arm brace, you mentioned that it fits with the 3" dp, can i see pix, i just wanna see what the setup looks like from under.
oh also, when i search the progress website, theres nothing there about a brace, any part numbers or info?
much appreciated as always

No I have the Hot Shot 2.5" DP however I think a 3" would clear. If the brace is not on their site why not give them a call?
Hey Wes, long time no chat. I am getting the bottom end built as well as the head. Looking forward to getting the engine dynoed whenever I get some more money to finish all of this motor work.
As Myoung, morepower2, & nizzan4u2nv have stated this setup is not correct for best performance of the GA and I would tell anyone to go with what everyone else has researched and have done that testing on. For me, when I started this project to turbo my car in 1999, my goal was to have a turbo setup on my car running and pulling as close to 200hp if not more in a year. At that time I didn't know much about turbo's and there full function such as best setup combination, what size would work best, or anything like that but I do know alot more now due to the NPM articles and other readings I have done. I still tell everyone to go with the Hotshot JWT setup because they have done much more research and testing than I have. But like Wes said "to each his own."
Wish you guys all the best with your GA and looking forward to reading more articles about your car Wes.
