Here is a few pics of my rebuild. Pre and post ports etc. Thought some of you might be interested in them. To see the rest you can go to my rebuild folder.

Re: Pics of 1.8t rebuild on my APR Stage III Passat- (Boosted VW)

What? I have had the stage III kit on my car since Feb. of 2000. As far as the T3 goes I will just have to stomach getting my rear end kicked by the ATP and PES kit. Hmmm, something tells me I just might be able stay close....You guys just slay me thingking the APR kit is a slow overpriced piece of (fill in the blank)

You've been one of the most helpful S3 Passat owners here, if not the most helpful! You thought you had a bad bearing somewhere which consituted pulling the motor out/apart - was it what you thought it was? You had the S3, cams and I can't remember what else - did you mod anything while it was apart?

Any new improvements like lowered compression, cams, etc? Very nice. http://****************.com/smile/emthup.gif

rebuild facts-

By the way, I know everyone does not think that. Initial tip something was wrong was sound of rod knock. Did not find anything that stood out as what caused the damage. I did the entire rebuild myself except the machining. I have over 2,000 miles on it now and everything seems good and the car runs like a banshee. I do not believe I lost any low end with all of the poting and hogging out. I actually may have gained some and the equivalent boost is now being seem about 200 rpm sooner than before. Could just be a side effect of the motor being new again. Plan an putting the car back on the rollers and see what improvements were actually made soon.
Rebuild consisted of stock pistons machined to accept Total Seal ring set. Everything port matched; intake/head, exhaust/ex. manifold, throttle body/intake and cast intake elbow to the turbo. Opened up the ports both intake and exhaust. New rod bearings and reused main bearings. The mains were in absoulute perfect shape and all of the jounals measured as being brand new so no work was done to the crank. The block also had almost no measueable wear so it was the bores were just cleaned up and re-honed. The head also recieved a valvejob.
Changes from stock:
obviously stage III
Schrick camset
front mount intercooler
2.5 in techtonics/flowmaster muffler
APR light weight flywheel and clutch package

I've never seen a 1.8 crank, that's one hell of a piece

Re: rebuild facts- (MYAPRSTAGEIII)

Any Idea why the engine went? how many miles did you have with the big turbo? I believe Billy has had 300whp+ for over 10000mi, did you just get a bad engine? Any idea how many passats out there with the stage III kit?

Re: rebuild facts- (jim wilson)

Did not see anything that pointed directly at the culprit. Who knows? I can tell you that those con rod bearings are pricey SOB's. Big turbo had about 35,000 but the motor had been at least chipped since the very first week. As far as Billy goes I don't know what he shifts at but with the stock cams he may not have to rev his motor as high as I do. That may have contributed? I think I have a permanent DTC for bumping into the 7400 rpm rev limiter. As far as the number of Passat I really do not know. I am guessing there is around a dozen or so sneaking around. The motor really feels like it responded well to the head work. Mostly top end but that was to be expected. Hope to dyno soon!

That's for sure. You're one of the few that actually post your experiences with a big turbo kit on a Passat and you're not trying to sell anything. You should visit ClubB5 more often! Thanks for the info.

Re: rebuild facts- (91 16V Jetta)

91, where have you been. You need to put a T3/T4 on the passat

Re: rebuild facts- (jim wilson)

Great pics. I'm somewhat surprised you didn't change the pistons or other parts while you were at it, but it looks like a very thorough job. I'm glad the engine was in good shape.
Have you considered a full 3" Exhaust like the forced motion? I've been waiting for that, since according to the guides I've seen, 3" is an ideal size for the 300hp range for forced induction. My only concern is the cat issue of whether I should use the APR cat or the Forced Motion one, and how difficult it would be to get the APR one off the turbo. Was that difficult for you?
I'm looking forward to your dyno results.

BTW, I have a Stage III, and I'm happy to talk, but most people haven't seen that interested typically.

Nice Pics!! That APR exhuast maniffold is absolutely gorgeous. Glad the rebuild went well...hope you put down some good numbers on the dyno. BTW what did you put down before hand?

I agree I think I would have lowered the compression via the pistons and upped the boost a bit more if I already had the head apart. While I was at it I would upgrade the wrist pins. They are the weakest link I belive in the internals.

 

[MYAPRSTAGEIII]

I did consider the route of upgraded pistons but

after looking into it the cost was just alot more than I wanted to spend and probably would have added another month or two on the down time. I had the piston assembly cryo treated and with billyt putting down a good bit more than I was without trouble I decided it was not worth it. As far as the wrist pin being the weak link, at least in my case I disagree and would say the rod bearings are the weak link. Could come back to bite me but who knows. I was getting 260(regualr 91 program)at the wheels before at one mile above sea level. I would like to see 300+ this time on the 100 octane program. I am looking into a 3" exhaust. I am pretty close to ordering ATP's 3" down-pipe and changeing it around to work with APR's turbo. Have not heard of anyone actually making a 3" exhaust for the Passat though. Do you know something I don't? I wish they would.

Re: I did consider the route of upgraded pistons but (MYAPRSTAGEIII)

Doesn't Forced Motion have a 3" Passat exhaust or have one under development?

 

[jim wilson]

Re: I did consider the route of upgraded pistons but (MYAPRSTAGEIII)

Give me a couple weeks and I'll have a 3" dp that works with the passat and T3. It won't work with the APR manifold though(APR was first, I wish the other tuners would have stuck with one design on the as far as bolts in space).
GolfikT, the "headers"(I think everyone agrees they have the best manifold out there) are made by http://www.goapr.com and can only be purchased with their kit. If they would sell the hoses and manifold I for one would be happy to pay $2000(nothing like good fit with stock look).
MYAPRSTAGEIII, if you could take off the turbo/manifold(now would be the time) and make a jig of the 3 dp bolts and 13 manifold bolts($10 in threaded rod and angle) you could send it to Chris G or me and get a 3" DP made

intake ports on the head look nice

You guys should see the difference between the intake ports on the Passat head vs. the intake ports on the Golf/.Jetta/Beetle head. The Passat ports are way way way bigger. Hope to be putting a Passat head on soon, to see if it makes a difference. It looks like it should, no doubt, but I will need numbers to be sure.

Re: Pics of 1.8t rebuild on my APR Stage III Passat- (1.BillyT)

Believe me, I wish I had 3" all the way to the fricken tail pipe but that just does not seem possible right now as far a just purchasing an exhaust. I have my eye on the ATP 3" downpipe but it too will have to be modified to hook up to the Garrett. We all know(Passat owners)what that would mean as far as mmmhh....emissions. Looks like the cat will have to move to the bottom of the car. Hopefully to erase at least some of the question on how much altitude affects my turbo motor I am going to try and dyno it down in Phoeinx. Still about 1,000 feet but sure better than 1mile. When I had my K04 setup down there to visit it felt so much better than here in Colorado. Do have a big advantage on the NA cars though.
