TD04 time.

[WJM]

Ok guys, lets get some info and pics up on everyone that has taken the plunge to do the TD04 conversion...

 

My plans are to rotate the housing so that the compressor outlet is like stock...vertical, and make a new mount for the wastegate actuator...that will make things less complicated....possiby get a 90 welded onto the compresor housing so taht I have less of a headache getting intake piping done...otherwise...i'll have to make a custom silicone pipe intake.

your old turbo is still working good isn't it. and do you need more than 15lbs of boost. i'm just trying to see the advantage. the advantages i knew of was it was easier and cheaper to find. and the abiltiy for more boost. i'm not trying to dog the swap just looking for info. and a givin a bump

The VF7 really starts to lose its efficiency above 12-13psi.. by 15, its a hairdryer..

 

The TD04 not only has a larger compressor, it has larger inlet and outlets, thus providing better flow.. equivalent amount of air at lower boost

[rallyruss]

also the TDO4 waste gate is much larger and can control boost on a car that flows better than stock.

 

I had pics but cant find em now. I will do some searching. I sent them to caleb a while back.

 

good luck with the rotating housing. your gona need to get real creative with your waste gate.

and on the intake side its real easy to use a 90deg. silicone hose.

 

edit: posted one pic below. a few more in my galery.

Exactly.

 

More CFM with less work=more power.

 

See, the TD04 should flow the same amount of air at stock boost, 7.5 psi, than the VF7 at about 10~11.

 

Russ....thats one strange looking setup...and I cant see anything of the turbo. :-p

I have more pix that show it a bit beter in the galery. some still here on my computer.

 

the IC is sideways because without chopping the intake hose and stretching it that was the simplest way to keep the hoses short. it also lines up with the existing scoop theat way. I was concerned about boost leakage with a choped plastic hose. I also was not cool with smashing down or removing the body below the IC in the rear tire area.

you cant really see the turbo because its mostly covered with the heat shield that keeps the heat away from the turbo at lower speeds.

I have noticed a bit more low end power with my set up but not alot of gain at top end because the old one was over boosting at full throttle (as high as 15lbs.) and the TDO4 wastegate holds at stock boost level no problem.

I feel that as soon as I get the bugs worked out of my boost control system then I will really feel the benifit of my new system.

 

the IC is mounted solidly to the body and the tie bar. and gets good air flow. there is a rubber skirt that goes around it thats not in the pic to help direct air flow.

 

truthfully if I did it over I would go front mount IC. thats where an XT turbo would be perfect.

Something to consider: In plumbing hydraulic and air lines, a 90 degree elbow is equivalent to adding 7 to 9 feet of tubing. Keeping the hoses short by making sharp bends may be doing more harm than good.
