Well eah, but .82 turbo is what makes it a bit slower on the spool up, I think. the T70 I have now is .83 AR hot and .70 AR cold (with a T3 flange).

How's your sool up? do you find it responsive?

T70 is OK, but no way in hell it will give you full boost @ 4000 rpm, or 2-3 psi at 2K. I tried, and it isn't happening.

Also the "new" turbo is about 1/2 the weight of the T70.

 

More Development:

Cut the outlet off the T4 Compressor housing:






Prep the 90 degree extension elbow by cutting off one of the shoulders.


Attached to the housing using my favorite brazing torch and rods.






Now to the hot side...
Need to make it fit into the downpipe I have currently, which means
I need to weld a 3" v-band flange onto the turbo outlet (which is 2.5" currently.
but I already know what needs to be done to make that fit, so I'll do that tomorrow.

After that:
Remove the external waistgate, and block the holes in the manifold and dump pipe.
Take out the T70, bolt on the T3/T04B.
Move the oil lines from one to another and (10 min worth of work)
Hook up the turbo and the intake/charge pipes back into the turbocharger.

No biggie. Will be done over the weekend.

I've found downshifting to cure the problem.

Should be fun to hear your review of the new one though

 

Well, I am too lazy to downshift I want to step, and go from any RPM.
and because I need to rev like crazy to get thepower going, I noticed that my fuel consumption increased quite a bit compared to what it was before.

I used to get around 220 per tank, now it is more like 190. I do run it richer though, when in boost nowdays. So that can be attributed to the fact...

 

Yeah, I get about 180 per tank now, I used to get 240

Yeah I have found that the extra power has made me lazy also, usually I'm in 6th gear at 2-3K rpms and I step on the gas, and LAGGGGGG. All it takes is a quick downshift to 4th or 5th gear to get the juices flowing.

Yeah I made it rich everywhere also. I cruise at 14.7, I have made it fat daddy rich at port opening 6500, richened from 5inHg to 1psi range that was going lean to around 12-13 afr and <11 after 1psi . depending on how cold it is outside I am usually at 10.5 above 50 degrees ambient and normal water temps.

 

Yep, "LAGGGGG" is exactly why I am switching to the smaller turbo.

 

You guys cruise too much. You get better range on a tank of fuel with boost than I get N/A.

 

Lol, thats highway mileage.

I get about 90 miles to the tank when I'm playing around.

 

Yep, I'll burn 1/2 tank in an a half hour or less if I am tuning. and after that look at the milage, and it is like 20-30 miles...
Do a 10-12 psi pull at 10.5 AF, you can literally see the needle drop

 

Sounds Fun To Me

 

Done modifying the turbine.
Now it has a V-band 3" outlet, instead of 3bolt 2.5" outlet

 

This project is very interesting, especially the idea of a mid mount kit.

Keep up the good work RotoRocks!!!!

 

Thanks, Man. I appreciate the kind word

 

OK, about 12 hours of work later I took it for a ride.
13 PSI, and Int-X shuts off fuel at 4100 RPM in 2nd gear (not 4rth, or 5th when there is a lot of load)
That is what I am talking about when it comes to spooling.
I did screwed up though, and put the boost controller hose onto the wrong side of the waistgate actuator. It was at the end, of the day today. I was exhausted, and got confused.
...Going to have to jack the car up again tomorrow, and get to it.
Oh, and I did move the intake into the engine bay.

You should hear the noise this turbo makes
I will make a video, because it will be totally worth it.

 

Couldn't allow myself to drive to work with unmanageable boost, so I went ahead and jacked the car early in the morning, and moved actuator hose onto to the correct side.
Instantly fixed the boost spike issue. right now it runs at 8 PSI flawlessly.
And i will raze the boost to 11-12 within the next couple of days.
But let me tell ya... This thing is awesome! It pulls so strong from the very beginning, and no need to even give it a whole lot of throttle to get into boost. Blip that pedal a little and you instantly hear "fffssssssssssss" as the turbo spools up and the car takes off...
I must say that I am very, very impressed with my own car.

 

LOL....nice! First laugh of the morning. Can't wait to see the final kit you put into production.

 

Thats so awesome, I might have to get one of your beta kits

 

Ha ha, I am betaing it myself for now but if you want, I'll make you one also.

 

Damn this thing is fun at 14 PSI!

 

Stop teasing us....

 

Well ok, no more teasing...
Here is the truth: It is running actually at about 5 psi...













...@ 2500 rpm

 

Grrrr....
