well guys I took it out for its maiden voyage. heres how she looks as of now.



Well after all the complications I get it started up my friend was with me and said that it still starts right up how it used to (pump the pedal once and it fires right up w/o the choke). sooo I back it up once again, no puddles this time and head into the parkign lot next to our garage, and do a circle around it, I got on it a little bit just to get a feeling for it and came back around and floored it! well about 3/4 the way through the parking lot I feel boost. but I had to let off.... I went down a street where theres more room that leads to another parking lot and get on it again... it almost seems as if Im driving around with a 100mm turbo on a stock civic.

nothing till about 30mph then BOOOST! and you hold on. unfortunately it was short lived when an intercooler coupler came off. I went back tightened it up and went again, same thing and I came home. I can honestly saw im pretty disappointed it takes so long to spool up. I dont know if its because of the size of the turbo or a leak or because of the motor takign its time because of it not being tuned. I never got it up to 5k because I want to keep the motor together for now. I watched the video from when I put the 8" rear in and remember the insta-spooling. I Cant even brake torque anymore! well I work basically all this week so not much new will happen however I will get enough of the exhaust done for the wideband and see about buying some jets.

I am guessing the fact that I am running taller tires, and a rear with 2.7 something gears its not helping the slow start off. anyone have any ideas?
 
get some better gears...


you know that little RBH5 was WAY too small for a 200 and that is why you had instant boost. how much boost are you running on it? see how it runs once you get it out to the track.
 
lol yea that instant boost was soooo nice. lol I have a wastegate with a 10 psi spring. I didnt have the boost gauge hooked up so I cant verify that it is actually 10psi though. I need an accurate one and figred I wouldnt rev it out to see if I could blow it, Ill get one ordered real quick and yea I will hopefully get it to the track next week Im guessing. I honestly dont think it will do that well because of the take off... itll be half track until it actually spools... ok so not that far but once it gets going... lol

I also edited the picture sorry bout that...
 
That hot side housing looks a little big. What's the A/R? .93? Larger?

Installation looks good though!

the hot side is an "O" trim 1.00 a/r t3, and the compressor is a t5/6, I dont have a compressor map however it is inbetween the S3 and the V1 compressors. I belive the compressor wheel is 52mm not sure on the a/r

Thinking about it I'm guessing the disappointment will be shortlived. I believe that once I get working on tuning it will help. I did the brake line mod with the carb to get some more air/fuel in there like does10s did. working with the stock gears and converter and going from a turbo bolted to the manifold with about a foot of piping from the turbo outlet to the carb with instant boost, and 3.50 gears in the rear it would seem a little faster on takeof... but once it goes, IT GOES. Im gonna work on getting gauges hooked up to make sure everything is working properly and see what kind of boost is being made. I cant wait to get it out to the track.

thanks for all the compliments... also thte turbo looks bigger than it really is because of it being closer int hte picture.

heres the maps and compressor wheels:

Tommy,

You sure have ramped up the WOW! factor. Get that puppy dialed in and you'll never say I wished I had my old setup...

Now I need to get off my butt and get it hooked up. Despite the comment posted previously about it being too small, I think it will be perfect for my weekend cruiser.

that hot side does look HUGE!
Run dual turbos, small for early boost, then the big one for the top end!

looks sweet though, nice install.

I can definately say it wont be too small for a weekend driver... as of now this thing isnt fun to drive aroud town... the old setup wasnt good either though because it would spool fast and I couuld never drive it easy. thanks for the compliments agian... I ordered some more chrome for another 15 hp! ,aybe that will get it off quicker. :wink:

are you running a pressure regulator?

lol I was wondering about that. and thanks! I figured it was just taking this long for you to get me back
 
Tommy,
I'll have to say your new set up looks great. Good job!

I'm not exactly familiar with your exhaust turbine side but if its like most old school wheels, that 1.00 A/R would be more suited for a 5 mile land speed record run. Is that turbine housing on center or tangential? The tang housing is a little more efficient. With a .96 it took me 3/4 track to get 15 lbs boost. With a .68 boost came very fast and overpowered my waste gate. But I was revving it to 6500. What I'm trying to say is exhaust housings are something you have to try. I think you'd be better off with a .68 on a street-strip car. Some people run smaller A/R on the street and change to a larger one for track use.

Mustang-Geezer has a line on a higher stall converter if I remember right, that would help. A 350 gear sounds about right.

Keep your exhaust as large as possible. It will also help your spool time.

Don't let your foot get ahead of your tune. You must know what your air fuel, timing and boost is.

If you don't have torque strap on the engine I would recommend one. The turbo is large enough to make some serious torque. I'm afraid the stock mounts will flex too much and rip apart. It may help with hoses pulling off.

Good luck!

woah... that last comment kind of cought me off guard... I never really thought about that. The turbine is a "O" - trim with 1.00 A/R tangential housing, T3 inlet flange, V-band outlet. I ordered that housing for the reason of it "having better flow than .68 for a little more top end power" lol I think I was upset with not being able to spin the old ihi to 6k rpms so I may have got more than what I wanted. I guess I'll see when I get it dialed in. Im not tooo worried abotu it being a street car, the only time it will be on the street is going to a show or something, its not goign to be my daily driver again.
 
Yep, I put some bids in on it but couldn't fit it in the budget. Now that I actually have a job, however...

Anyhow. I think a .68 or .72 housing (whichever you can find) would be a good match for a 200 that sees occasional track use.
 
Yeah Tommy, lookin' good buddy.

That 1.0 AR turbine does seem big, though and I know you don't want to hear that. Heck you are over twice the size of my .48 AR on the bronco and it spools fast, but not as fast as your smaller turbo you had. Since you are on a t3 flange, can you not downsize to a smaller turbine housing, maybe an .82 or something closer?
