I've been told otherwise here...

If you run an apex seal threw the exaust housing and kill the wheel you'll need to order a P trim standard shaft for about $120-180 depending on where you get it from + the overhaul kit.. If you kill the compressor side your fucked, but you could easily just buy a 62-1 or other standard shaft compressor assembly to replace it for around $500 or so. However you usually won't hurt the compressor side unless you put it together wrong and back spin the nut off, suck somthing in to it or have totally fucked bearings.. you should check shaft play and thrust play on a turbo at least once a month to catch this and you'll be able to catch when they are going bad before there is any damage to the compressor housing components.. I own 2 TO4R's and I've rebuilt mine 3 times in the last 3 years... 18-20 psi will wear out bearings about once a year or so do to thrust pressure and high shaft rpm's on the bearings, due to the fairly heavy and big comressor wheel...

They have been enlightened... https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

how do you think a t04r will do with the massive exhaust flow of a 20b?

Sounds too small to me, but I don't have a 20b.

When i was researching it before I bought this T2 setup I found that you need a HUGE turbo to make a good power level on it because the added displacement makes for alot more breathing.I sill might pick up a T04R for this engine tho. https://www.nopistons.com/forums/pub...#>/biggrin.png I just need to find a car now to drop it in.

for a 20B you'll want a T76 or so turbo with a Q-trim exaust and A/R .96 or bigger ex housing.. I'd go with a 1.30 ex housing if it was me...

how does a t04r 63t .96 sound on a s5 t2? dragon would you recommend a t04r or a gt35/40 for minimal street use and more drag use applications?



luigi

to4R would be better for dragging

Definitly the T04R or you could go bigger.. https://www.nopistons.com/forums/pub...IR#>/smile.png

can you go bigger than this and still feel comfortable on the street. what would you recommend sense you had/have this turbo? and the t04r will produce more hp power than the gt35/40, right?



luigi

Vosko says his t78 is fine on the street, I would say T88/tr1 would be max, but this is mainly a drag application right? Yes, to4R will produce more hp than the gt 35/40.

is the t78 bigger than the t04r? (its ok if you talk to me like i'm stupid). is the manifold for the the t78 also based on a t04 platform (not sure if this is the correct terminology)?



luigi

Isn't a T04R big enough?For street use anyway. https://www.nopistons.com/forums/pub...R#>/unsure.png

The To4R and T78 are very simular in what they can do.. the TD07 and To4 also use the same exact manifold flange and they are both great for street use.. I should have my T70 on the car and running here in the next week or so. I can let you know what it's like driving that monster around on the street after I get it all pieced together... https://www.nopistons.com/forums/pub...IR#>/smile.png

Hell yeah. https://www.nopistons.com/forums/pub...#>/biggrin.png

This'll give you 500 flywheel hp @ 15 psi with a half decent port job.

That wheel looks too tiny to produce that kinda power.

Are you sure?? https://www.nopistons.com/forums/pub...#>/biggrin.png

wow NICE!

ok, what the hell turbo is that, it says A/R 66 on it, but it looks like a a/r .84 housing... it also looks like its got a fucken huge ex housing.. 1.15 or 1.3 or so...



It's also nice to see people sticking their aeromotive fuel pressure regulators where I put mine.. Whooo hoooo, I'm a trend setter.. https://www.nopistons.com/forums/pub...#>/biggrin.png

is that a t04r? and are you saying, dragon, that the td07 25g have similar power output to the t04r? and is this ac orrect order: bigger to smaller



t51r spl

t51r kai

t88

t04r

t78

td07 25g



sorry for all the q's, very interested to know as i am exploring the opportunity to sell my fd for a fc (i've made up my mind and there is no changing it).

Actually, it's the smaller of two choices. This one is bigger. It's a Magnus GT42.

whoa custom thermostat housing to fit that bad boy eh ?

not the TD07 25G.. the T78 and TO4R are very simular, the TDo7, T78 use the same type of flange as the garret T04 series turbos'



The T70 going on my car now is pretty much the same a the T51R Kai (actually a little bit bigger than the Kai) and it's getting stuck on a T51R Kai manifold with a 60 mm V band GT wastgate using a to4 to T51 V-band adapter flange.. for future referance the T76 is pretty much the same size as a T51Rspl...

So Tyson what exactly is that on your car? I thought you got the GT42 from Magnus. They have some pretty sick **** up there. I just wish I had the $$$ to get one of his kits.



Do you have any dyno sheets for his turbos?

The turbos are the same, I was refering to Dragons comment on the exhaust housing size. Mine is the smaller one, while Paul's is the larger.



Paul made 425 hp @ 1 bar with a very mild street port. If you can get your hands on the first issue of MODIFIED mag, you will see a dyno sheet from Jeffrelito. That car had a small half bridge and the smaller exhaust housing like mine. It made 463 hp @ 15 psi, 505 @ 20 psi and has since made about 590 hp @ I think 26 psi.



Check out Magnus Motorsports

Yeah I've seen the site. Do you have a half bridge too, or just a big SP?



So basically the GT42 is a little smaller then a t51r, with a little less power output? Is it ballbearing like the other GT series turbos?

cool, from that angle it looked like a to4e wheel w/ some huge housing.

This here will getcha about 1700 rwhp ... of course you would also need that viper v10 to go along with it. https://www.nopistons.com/forums/pub...#>/biggrin.png

I wouldn't know how to compare it to a T51, I would say they are the same size. No one here has really maxed out the potential of a 850 - 900 hp turbo anyway.

It is a full ball bearing turbo. I think Marco mentioned he'd seen one run for 2 minutes after turning off the car.

At 15 psi there are a dozen popular turbos that can make similar numbers. Big turbos begin to come on above 20 psi or with crazy porting. No sense flowing more air than your engine can use.

I have stock ports. My engine has never been rebuilt as far as I know. The reason I chose to such a large turbo was so when I finally do need to rebuild the motor, I can do whatever I want without having to worry that my turbo is too small.

Yes yes Tyson, nice big turbo, must go for ride in such turbo car, must feel da booost mon, of the

Marco Magnus spec gt 42, hey lemme know when its good to go, I wanna go for a spin



you gonna set it up for 1 bar? or 1bar+



oh ya and congrats man, I know it's been a crazy long wait for you car

I was basing that comment off of other dyno #'s I've seen on lagre turbos. I know Ray Wilson from PFS made 650+ to the wheels at around 30psi on a street ported motor running a t51r. I was just assuming https://www.nopistons.com/forums/pub...IR#>/wacko.png

I don't know if Jeffrilito ever ran @ 30 psi on the dyno or how close to the edge the tuning was. We'll see how hungry Paul is for power this season, but I don't think he will need to go that high. I definitely won't this year, as I will not be on the strip. I would get booted anyway, I don't have a cage. https://www.nopistons.com/forums/pub...#>/biggrin.png As it is, it looks like I might not be able to compete in SOLO I either without the cage, because of my engine mods. https://www.nopistons.com/forums/pub...IR#>/blush.png
