I'm sure it would work well but i figure if you're going to go 8 feet why not go all the way! I guess theoretically it would be best to keep the two exhaust flows from ever joining to reduce turbulence but for most applications it probably wouldn't make a big difference anyway. I think most ppl join the gate into the main exhaust stream about a foot back from the turbo. Think about those champ cars, they didnt join the wastegate outlets with the main exhaust streams! haha.

Thickness could get a little tricky with those extra donuts that peugeot puts in the manifold. Like Toni said, if it's too thin those may interfere with gasket sealing. Of course you don't want it super thick either. I suppose you could just try it the same thickness as oem and hope that they don't crush much more. Besides what is oem made out of? It seems to have multiple layers, some of which look like copper and maybe a stainless layer? Haven't paid much attention to them. I doubt it'll be a big issue as long as the thickness is reasonably close to oem. We could get a thickness measurement on a new oem gasket, and then get one on a 'used' gasket (i have a used one i can measure). Then we'll have a rough range of operation. Maybe the shop will have your answer? Oh man, o-rings on the intake manifold sounds like a pretty cool idea. Although i'm hoping i never have to take the thing off again... or maybe just until i make my own intake manifold? what? HAHA.

ahh, nice! I still would like to do one up for myself one of these days. So many projects with this car, it's hard to keep up with myself.

Sounds promising. I was even thinking about making the rod adjustable length much like a steering linkage rod so that you could adjust engagement... but maybe i just get too many ridiculous ideas that are unnecessary... probably the case. Anybody who keeps trying to use bearings when a simple bushing should suffice should get their head checked, right? I'd love to see the solution that you come up with! I'm probably going to be working on mine again soon.

By the way, the honda crx turbo guys used to do some nice work with the old civic HF manifolds adapting them to T3 flanges. They basically used a fairly thick steel adapter with counterbored holes that bolt to the original manifold. Then the adapter had a T3 flange pattern in it too. It's probably possible with the N9t setup although it would push the turbo down a little... hmm, maybe too much. My vote would still go to just fabricating a new manifold. it can't be THAT hard Talk about TRICK! V-M knows how it's done.

August: Remember the wrx STI video i had claiming 385 whp? That guy had his wastegate flow straight out and down and just dump to atmosphere. There are pics somewhere but we'd have to ask Kenny. He said it was LOUD when that thing opened up...like serious loudness. All this turbo+exhaust talk has me scheming about exhaust systems again.... hold me back plz i can't spend anymore money. I think the 3" system i put together is gonna turn out to be useless... but i still dont know yet. It was fun to make anyway. I'm too stubborn to reduce the pipe to 2.5 to get over the crossmember because it's just gonna be a big bottleneck anyway, and the downpipe transition has always been too ghetto for my taste. I keep thinking about a 2.5 turbo back, with a dedicated pipe (maybe 1.5" or so) for wastegate... oh dear would that be ridiculous. a little tiny striaght through muffler for the wastegate and a nice magnaflow for the 2.5". Of course that would require a new turbo and all... Well, let me know when you get your turbo august, we'll make the exhaust dreams a reality with your car... Honestly right now i'd be happy with a stock system that hadn't been muffler-shop hacked, with a magnaflow 2.5" on the back. thanks mufflers-R-us and previous owner... :-/

That sounds awesome! Take some pics if you can, i'd love to check them out. Sorry about the lost wheel but i'm glad it seems to be working out well anyway! Good stuff!!!!

I made a tracing of the intake manifold gasket as well... since these things are getting hard to find i wonder if we should scan them into the computer and save a to-scale copy as a big image or something, we could store it here on the site. Just in case....

Does it look like this: I've had the same problem with mine. First i had a friend weld some more material onto the rod and then shaved it back down to normal diameter. I still wasn't happy. I drilled out the pedal a little and put a captured ball bearing in there with the rod through it. It was an awesome solution, but the bearings were small and they couldn't hold the load for all that long.. a couple weeks and they were falling apart. here's the first fix: After the bearings went south, I ordered a roller bearing (needle bearing) from mcmaster that was a little beefier and tried that. I have yet to check how the roller bearing is holding up but hopefully i'll be able to check it out within the next week or so. Unforunately i had to grind the rod down to fit through the bearing, and it isn't totally round and true. I didn't have time to implement a totally high quality solution.. but it still works without any sign of failure. I'd like to settle this issue with a permanent fix as well, so please, anybody who's dealt with this speak up! I would assume that a bronze bushing with a little grease might work just as well as anything. The tiny bearings seem a little fragile for the loading

I can't seem to find the pictures on your site. Could you provide a link?

very nice!

oh man that is perfect.

AGGRESIVO

I see what you mean about the wastegate looking more 'fixed.' But take a look at the middle two pics and the wastegate mounting in relation to the compressor outlet. Doesn't it look like its in a different position in each of the pics?? Hmmm I like the exhaust outlet as well... looks like it would be compatible with some good custom stuff. Although i have heard of performance differences when the wastegate joins the exhaust stream at different locations. I wonder how it effects exhaust flow by just dumping right in immediately like our oem turbos.

I think you can usually rotate both halves, and you can switch the wastegate mounting bolts with one of the other clamp locations. There are little load distribution washers that clamp the housings together to seal, and the wastegate bracket serves as one of those.. At least that's the way the stock turbo works but i think it's pretty standard? Aren't the newer generation turbos supposed to have greater efficiency overall as well due to better impeller design? Maybe less turbulence / less heat?

BAHHAHAH! classic! a trunkless 505! Does it qualify as a hatchback?

Offset maybe?

It's not looking too roomie... I can't get my finger between the tire and the strut on my 88 and i have small fingers. I'd say you have between 8 and 10 MM there. Between the actual rim and the strut there's probably about 15 mm. my tires are standard 205/60/15. I can't wait to see how you do it! It's definitely a cool idea, looks like it may be difficult but i'm sure you'll manage!

A TRUE "PIMP MOBILE"

Viscosity indices according to http://www.micapeak.com/info/oiled.html Interesting stuff, 90 seems like it covers a large portion of the higher index, i wonder if something like 75-85 would be a good choice... if they even make that. :--)

yea. It'd be awesome to find something that mated to the manifold, but wth a better downpipe flange that could accomidate some fabricated downpipe of a larger diameter... and improve exhaust flow by losing the chicane style outlet. We gotta look into it, but i think that the bolt pattern to the manifold may be the same as a more conventional t3, but the inner diameter is circular? if that's the case we may just be able to portmatch the stock manifold to a different turbo and use the same bolt hole pattern. that would make things easy on the manifold side.. then the exhaust would be no prob as long as it's something like a simple flange-style mate.

!!! It's on. I'll help you fabricate some stuff. All we need is a mig attachment :--) I still want to get rid of that turbo and put something else on my rig. You thinking new manifold or what?

Damn that thing looks nice! I saw that auction and knew you'd be all over it... and then looked closer to see your name as high bidder. haha. Awesome find, not a bad price either for a brand new turbo. That for the 89?

http://www.craigslist.org/nby/car/96772491.html man i wish i could just buy up a bunch of 505 turbos to play with. no space, no money.. :-(

Yea the back looks nice, i'm not too crazy about the front tho... Gotta love the hoodpins! Why the small sidewalls!??
