Anybody ever thought about turbo-ing a R53? I have a T3 turbo and intercooler, but don't really think it's the best idea.
I'm pushing around 18.5psi with just a CAI, -19% pulley, 380 JCW injectors Stock intercooler, RMW cam, and RMW tune. I'm happy, but mine is an '03 so my gearing isn't all there. ehhh

there are many many more r53 turbos out there, both twin charged and turbo only.

 

Ya I know about the whole twin charging thing.... I just don't think it's efficient. Yes you do get the boost form low rpm from the blower, and then boost from the turbo at higher rpms. But i'm talking about using almost everything stock (block, head, pistons, rods, valves, retaining springs...) and turbo it? Is it worth it? Can there be more efficient power with the right turbo set-up?
No crazy HP numbers, just something for the track?

 

For the same amount of boost pressure a turbo will give you more power due to less parasitic "drag" on the engine. In other words you can leave everything the same, the only big adjustment you need to make (aside from all the stuff required on any turbo system) is an electric water pump. The stock water pump is driven off the supercharger so when you get rid of the SC you need the electric.

I dont know of anyone who makes a turbo manifold for these cars, so you either make your own yourself or contract that out. The rest is fairly straight forward fabrication.

 

But......but the whine! NOOOOOOOOOOOOOO!!!!!!!!!

 

Yeah... it's been done... pretty much since the car was new... IIRC, Fireball Tim's drag car was a turbo-only conversion... Is it worth it? Hard to say... How fast can you afford to go?

 

A R53 with no SC whine?! I think that is a felony in most states!

 

The 300whp+ makes up for it...

 

Good talk, but is it efficient? I track the car and drive it everyday.

 

dU=dQ-dW

The supercharger pressurizes the air with strictly W_out from the engine, whereas the turbo uses a lot of Q_out from the exhaust gas a and a little bit of W_out from the engine. Since the Q_out from the engine doesnt get used for anything anyway, the system gets you more gain with less loss.

In other words, if you werent tuning the engine for all out power, you would probably end up with better mileage from the turbo.

 

if you are going to track it , it's tough to beat a fully setup supercharged Mini
we have kits being made for the Rotrex now

 

so when is the tvs coming out for the 1.6 or is it just better to get the rotrex?

 

TVS is vaporware at the moment.

 

Hardly...

 

Eaton would actually have to make one small enough for our before a kit is developed. When will that be with the Auto industry hurting like it is .

As for me I could care less as I have and love the Rotrex SC .

Longboard

 

Rotrex FTW!

 

Look and this:

Turbo only

 

Sorry, im a noob, but is the links that glnr13 posted have a the supercharger and turbo?

 

the first link is turbo only and the second and third links are twincharged.

 

Turbos sound real good too

 

Building a car like the one you are talking about would be a good weekend car....but IMO not a good reliable daily driver. They usually require lots of tinkering to keep running just right.....

 

Couldnt agree more....I miss being able to just jump in and drive at any given time, but that's mostly due to other issues other than my turbo setup.

 

TrickleX are you still having clutch issues???

where is a good place to look for a turbo kit? mostly looking for the custom manifold i guess...alta used to make it, anyone making one now??

 

when will be these kits out and how much?
