Well guys,

I'm finally home after being sent to Texas for a 2 month assignment. And now I've got a bunch of new parts ready to be put on. But the most important of them was the turbo.

The only thing holding up the turbo project. Turbonetics T-76 Ball Bearing Q-trim with a .96 a/r. Its a very cool looking turbo. The ball bearing definatly nicer than the older style bearings. With the turbo sitting on the table I can blow into the exhaust turbine and the turbo will spin, that's a pretty low drag.

I'm going to be putting this on my spare engine. 350ci Iron head, with a 230/236 cam everything else stock. I think it has a leaky head gasket, but if I do blow it it will be a good excuse to put my low compression stroker motor in. But I'm guessing it will be ok long enough for me to work some of the kinks out of the turbo system and get a feel for how everything goes.

The only things that I have left to do is to move the power steering resevoir(anybody know the hose diameter?), mount the oil cooler somewhere(probably infront of the ps cooler), and maybe finish the exhaust from the rear axel out the back. I think I should be able to get most of this done this weekend but we'll see. Hopefully I'll have an update come Monday.

The only

 

get-er-done!!

lol.. good job man can't wait to hear about it getting finished. I just finished a big move and have to unpack my gfarage and unload the garage of furniture to make room to get the car back in and finish the tweaks that need to be done.. shouldn't be too long.. gimme a ring if ya have any questions with the power steering res.. it was a pain in the rump and I may be able to lend a hand with fitment stuff. the only thing is the resevoir I used had the feed on the bottom and the return on the top side above the fluis level.. but i think the stock unit has a channel inside that dumps the return fluid above the level line anyways.. may just be a pain in the *** getting the connection made. lemme know!

Well, I took yesterday off work so now I have two nights and one and a half days in to installing the kit. And if you looked at it you would say that I really didn't do much. But I have the PS resivoir relocated to the pass side, I modified all of the coolant hoses in the car excet for the one that goes from the resivoir to the heater core. There should be enough room for the turbo now. I moved the fuel lines, removed the blower box. And I spent this morning replacing the oil pan with one that has a welded in 1" oil return pipe. Its really not fun putting a deep well oil pan on a motor while its still in the car. I had to take out one of the motor mounts and hoist the engine up to get the clearance.

I'm hoping to have the exhaust pipes on tonight and maybe the IC and intake piping as well. Then come the little things like swapping injectors, rewireing the wideband stuff to the other side of the car, and a few other little things.

The only problem that I have run into so far is that I had to put a plate under my thermostat housing to turn it and that moved it farther up and I think I'm going to need a thinner TB adapter for the intake piping. Right now I'm using a 4" to 3" black sewer fitting. Does anybody know where I can get a silicon reducer that would fit??

I wish I had some pics to show you guys, but there's not a lot to show right now.

 

One 5" to 3" silicon reducer coming up. Blue or Black?

Now I need to find a 5" to 4" reducer. Can't seem to find that.

Bruce has one on his car. I believe he bought it from ATPturbo. It was A while back I could be wrong.

 

Awesome man.. I knew ya would get the bug after I got mine going..lol so any updates yet? lemme know man.. eagerly waiting!

Chris

 

Well, here's the weekend report. I have all the pre turbo exhaust piping installed, the turbo itself, and the intercooler. I'm having some issues with the intercooler piping hitting the hood.

But the coolant lines are finished, and half of the plug wires are done. There's just so much little crap that keeps getting in the way and I seem to be having issues with everything.

I did order the silicone reducer from that company, Thanks AKS. But they only had blue which is sad so I guess if it works I'll order a black one later.

Unfortunately I'm feeling the beginnings of burnout on the project. After three days of problems and frustrations I think I need to take a day off and relax for a bit.

 

MN vette,

do you have a camera you can snap some pics of the IC setup... I have hear a claw style intake which I can measure and send you the dimensions of the pipes they use.. there are 3 flat spots on the bottom which set tight against the radiator shroud.. I think this is about the only way to get anything to fit above the shroud and under the hood.. its tight in there.. which is why I went with the front mount location.. was too difficult to get it to go the other way.. I know your turbo is a little bit further forward then mine but if you can get a pipe turned down in front of the cross member you can pretty easity get the plumbing like I did mine to and from the IC to the TB. lemme know if I can help any!

Chris

 

Chris,

Thanks for the advice, But I think I fixed it during lunch today. A little clearing on the hood and a little vicing the pipe more oval and the hood closes just fine now. I'll have to put the radiator shroud back on and make sure that isn't in the way, and trim it if it does.

So hopefully I can get that done tonight and maybe the down pipe too. If there are no clearance issues I can start thinking of all the things I have left to do before startup.

 

sweet man.. sounds like your rocking and rollin.. don't get burned out so quickly.. the little things are things ya only have to do once.. after that removing and re-installing them isn't really that bad.. you have already done the majority work! keep your eyes focused on the goal!

just keep thinking pssssssssssshhhhhhhh..(add tire spin effect....here...)

Chris

 

Ok, so here's the update, down pipe is on and seems to clear everything nicely, IC and intake piping is all on except the last piece that goes to the TB, AND THE HOOD SHUTS!

So the only things I have left now are

1.) "Cat" back section of exhaust which I will finish after the car is running

2.) Relocating the O2 sensor to the down pipe

3.) New plug wires and hangers

4.) Install bigger injectors

5.) Make sure Thermostat housing isn't leaking

6.) Install new MAP sensor and set up tune to match

7.) Add more oil for bigger oil pan

I'm pretty sure thats all there is.

 

outstanding man.. I am glad to see its coming together.. I know you have a digital camera!!! snap some damned pics dude..lol now the nice thing is once your done.. all ya gotta do for big boost is swap in your new motor.. all the little things are done! should be no different then any other motor swap and maybe even easier!

keep us posted man!!

ps.. mine is going on the dyno Sunday.. waiting on My new T-bolt clamps.. I keep blowing apart intake tubes with the worm style cheap clamp you can get anywhere.. it makes me mad because I have a box slam full of T-bolt clamps that are just a hair too small.. guess I ordered wrong and forgot to add the thickness of the connecting silicone hoses.. ugh... at any rate I got a new video camera and will have some video of the car on the dyno and probably some of some small street testing, in car and from another car to give you FI guys some motivation!

Chris

 

I wish I had a digital camera. I may be able to swipe one next week. So after a little more work on it this week, not enough though, I've got a much smaller list.

1.) Finish post-tranny exhaust piping (will do after car is up and running)

2.) Relocate wideband box to new location

3.) Do initial tune for the car



Unfortunately I'm going back to my partents house for this weekend so I'll have to pick up on everything come Tuesday, but then comes volleyball and softball. I'm hoping everything will be ready to start the car up on Friday and that will give me the weekend to drive it around and debug all the problems, give the kit a few miles and see if I burn through any hoses or what not.

So tune in next week, same bat time, same bat channel

 

Brian,

I mounted my wideband module on the passenger side fender well facing the cockpit.. I was able to hook up the senseror in this location without using the extension as well.. then just ran my woring behind the dizzy to the junction point of the oem computer.. two bolts through the fender well.. fits perfectly and stays very dry and cool here! just a tip if your still hunting for a spot to put it.. lemme see if I have a picture, tucks out of the way and is inconspicuous there as well.. I have to point it out as being part of the DFI as most people just think its part of the stock wiring.

chris

 

You guys are killing me, lol.

[caveman]Neat want turbo C4. Neat mad. Neat jealous. Neat want turbo C4![/caveman]

Can't wait to see what your car makes on the dyno Chris!

Stay on it mn_vette, a bunch of us are pulling for you!

 

ITS ALIVE!!!!! well sort of.

I fired it up and managed to get most of the burn off gone from the headers and dp. You can actually hear the whistle pretty well, especially after a good blast and the rpm's die away, thanks BB.

So here's the bad news, my little addapter plate that turned the thermostat housing is leaking. I'm not exactly sure how I'm going to fix it other than welding it shut, but I don't know if the metals are compatable to weld. So until I get that hammered out the car just sits.

Other than that I forgot to put the plug in the boost reference hole at the end of the dicharge tube.

This thing is LOUD! even at idle its way to loud to drive on the street. I'm going to have to order some kind of muffler setup for the thingI guess the easiest way would be to hack up my stock setup, but I'm not sure I want to do that. Maybe I'll order a pair of flowmasters or something and see if I can get them here by this weekend.

 

Ok, this has been keeping me up all night. What do you guys think I should do.

1.) Cut up my old exhaust and use the stock mufflers to get the car on the road

2.) Rebuild the rear exhaust section with 3" pipe and a set of flowmaster delta 50 mufflers



I called summit and they can get me the mufflers by friday if I call them before 6pm today. Which should be enough time to figure out exactly which flowmasters to pick out. But I also don't want to spend the extra $3-400 on that and waste my weekend when I could be having the car running and debugging the system. I know using the stock setup will eat up horsepower, how much I'm not sure, but some. Perhaps I should keep the flowmaster for a winter project though. I'm not sure.

Lets hear some opinions....

 

Get a B&B system...it's 3" all the way back (except for a 2.5" reducer in the resonator)...

Should work really well with your setup....and you can probably get one for a good price used.

Try this link out... http://forums.corvetteforum.com/show...hlight=triflow

 

get some 3" pipe and some 3" bullet dynomax mufflers from your local parts store.. I am running them on mine and quieted it down considerably, no wait for friday, and I would not use a chambered style muffler on a turbo car... it doesn't need it.. a straight through design with perforation turned mine close back to stock with no cats on the car.

just a thought!

Chris

 

So...if your system works so well, why did you jump over to the linked thread and ask TJ Wong if his B&B system was still available???

Unless, of course, it is for another car....
