You running fans on the front then? Doesn't look like you'll be able to clear fans in the engine bay.

ill get slim frans for inside engine bay cuz the intercooler is going in front.

is that the legacy radiator? is it a single core or a dual core?

just curious cause eg33 are notorious for having cooling issues and the stock svx rad is a dual core.

nice to see somebody else making some progress with their h6 swap tho!

would it be hard to turbo the h6?

its the turbo legacy radiator. single core...

well its going to require lots of custom work to turbo but its nothing i cant handle.

New crank

Nice! hopefully those fans are enough though.

yeah if they arnt ill most likely will keep them on everytime the car is at a dead stop or at all times

may i ask whats so funny?!

He means it's so tiny...

Lego · Post by **Lego** » Wed Jan 13, 2010 6:59 am

lol yeah its not even that big

Yep you should give it to me and get a REAL turbo:

(couldn't find a pic of the MTU series 4000 turbo but this should do)

How many lb/min do you plan on running with that turbo? The reason I ask is that your intercooler looks rather small for your application, especially being of a tube and fin design.

May I suggest mounting your radiator fans with an offset? If you offset the fans, you'll hit more tubes of your radiator, and possibly avoiding issues in hot weather when in traffic. I learned the hard way...

i plan to run 20psi. i wanted a big turbo so that i could keep it 20psi even at high rpm and this turbo will easily do that. my intercooler is a little bigger than shown in pic because the bumper covers some of it up.

i thought about that too with the fans but ill take a look and figure something out

Right on. What is the size of that comrpessor wheel? 20 psi on a 3.3L will be A LOT of power if the compressor stays efficient. Almost 60 lb/min, meaning about 600hp.

my turbo has a 9cm compressor but thats equals .65 so easily hold booost at 7k rpm

93forestpearl · Post by **93forestpearl** » Wed Jan 20, 2010 9:27 pm

I was talking about the comrpessor wheel, not the A/R of the turbine housing. The inducer of the compressor wheel is what determines how much power you can make with a given turbo, as long as the exhaust side matches.

That's enough to make a guy consider an H6 swap. lol I think if I did another project that would have to be it. After getting a 6spd first.

Compressor inducer: 54mm
Compressor exducer: 78mm
Turbine wheel: 58/65mm

The compressor wheel sizes are similar to a GT3076r and the turbine similar to a GT3276. Compressor and turbine trim are 48/79 respectively.

93forestpearl · Post by **93forestpearl** » Thu Jan 21, 2010 2:28 am

That's an interesting turbo. The inducer is a hair smaller than the 3076 but the exducer is larger. The turbine is larger too. I doubt you'll be able to maintain 20 psi to redline, but you could definitely hit that somewhere. The larger exducer should help the efficiency in the higher pressure ratios, but you won't be going that high with it.

My expectation is that your setup is have some monster torque and decent top-end HP. My prediction is 400whp and 450 whl-tq on pump gas, with a really sweet powerband.

There's no replacement for displacement.

well that would be cool to have those numbers but i guess ill have to wait till im fully done and hit a dyno
