Ok, gurus, what do you recommend?
My 89 N.A is almost complete, however we have a ? with what is the best exhaust setup.
The engine is bored over 1.00 mm and has a Giles IP and injectors.
IIRC, an exhaust manifold from a 1.8 gasser with a 2.25" exhaust pipe was the recommended setup (corrections welcomed). If you have part numbers handy, very much appreciated......
1.8 headers were ruled out for not long lasting.
As usual, many thanks.
Stay safe, stay well. Jimmy.

get the dual downpipe setup off an 88-89 8v Jetta w/ a PF code engine.. it will have the dual downpipe..

I hope this is the part you are suggesting??
Thanks again.

I believe he's talking about picking one out of the junkyard. If you're going to buy it from TT you might as well spend a few extra dollars and get the 4 to 1 headers IMHO.

Thanks for the reply. Seems for the cost of the TT manifold and pipe I can get the headers. For the life of me I cannot recall who told me to avoid the headers ( I think I asked once before, I'll check my pm's as well) for they would not last as long.
While we all know a 52 hp 1.6 NA will not win any races, with the Giles IP and a better exhaust, obviously ANY improvement in hp is a plus. The head on my original engine may be warped from going up the hills on NY Rt-17 in 3rd or 4th gear, so this new power is a big plus. And will help with the morons in NYC traffic who will bit*h and whine about fuel costs, but still drive an SUV like Mario Andretti.
So no better place to come for an answer than this site.
Again, many thanks.
Stay safe, stay well. Jimmy.

I believe people say to avoid the headers on a diesel because with the extra vibration of the engine it will eventually break/crack the header. I picked up a 8v manifold and dual downpipe for $75. They are around often in the vortex classifieds.
My exhaust manifold isn't in yet, but I also have a 1.6 NA with a Giles pump. ;)

Thanks. My 89 is a good distance away, and the guy who intalled it said it runs great with the Giles IP. So ordering the parts is the easy part. Once the exhaust is in, I should be able to get it back on the road. While I love my 09 TDI, there is something about driving that Mk2 that can't be explained......
But I'm certain most everyone on here knows that... :)
Good luck with your Giles IP.
Of course, everyone's opinion is appreciated and respected. Thanks again.

its got the original 89 n/a dp on it? If you were to look in to its outlet, and measure how large it is in there.. You will find it is nearly 2.5". It was the 1 5/8" exhaust that was after it that was the stock restrictive abomination lol.
If you run 2" (2.5" maximum on an na) to a good muffler out back and make sure it exits from under the car/bumper/rear valence you shouldnt have any drone issues.. with it being as straight through as possible.
I currently have my 91 na motor running about a 2" straight pipe with a 32" cherry bomb in the tunnel and it exiting driver side before the rear tire. Not to bad a drone, the engine gives off more sound of clack-clack-clack than the exhaust does anyway.. lmao

is your car a mk2?
if so, I have a set of headers that I bought before I got out of vw's that I could let go for a reasonable price...
PM me if you are interested.

Going to check on all the suggestions. Keep them coming.
As posted a million times, it amazes me what you guys do with these little N/A and TD's. Especially with rising fuel costs, its nice to get power and great mileage.
Taking my wife's Suburban to Maryland this weekend. I'm dreading the mileage on that pig.....
Would have dropped a 4BTA in this if I had the talent to do so... :)
I'll drop you a pm, Owen. Thanks.

if you brace it to the block in a couple places, you MIGHT get away with a header.. i ran a header on my rabbit, it worked alright, but it would have cracked had i kept running it without the lower block braces i built..
at a certain RPM, the header would BUZZ.. it was annoying. and the header didnt quite fit right, so it hit the body when you used reverse..
if it were me, i would avoid a tube header. theres going to be no benefit over a manifold and dual downpipe.. the mk2 engine mounts MIGHT be solid enough to get away with it, but there again, thats a big might..
and really, i think that all VW manifolds flow pretty well, but its what comes after the manifold (toilet bowl, down pipe, exhaust system) that is the restrictive part..
the manifold is going to be the piece that can go the distance.. its a *** to put a header on a mk2, i think i would stick with the dual downpipe and manifold. then you dont have to ALMOST pull your engine to get it in there..
i removed the manifold, and downpipe from my GTI with the engine whole, still in the car, then put in the dual d/p and mani in also. didnt have to pull the head like most do..

Hitting a few boneyards, I found that some of the dual downpipe/manifold setups weren't as large (in total cross-sectional area) as some of the singles; I'm sure others are larger. In the end (1.6NA) I used a 1.8 gasser single-exit manifold & downpipe (roughly 2.25" ID), cleaned up the obvious casting flash & mismatches with a die grinder, and had a 2.25" DP-back system made for it, flowing through a short 2.25" "Turbo" muffler. It was an immediate improvement over the constipated, garden hose-sized OEM exhaust system: the engine is just much more responsive/spunky/free-revving.
I also liked that I could fit the EGT probe in the center of the manifold's single outflow. Not as purty as ceramic-coated headers and no bragging rights; it just works.

How true. I recall the size of my stock exhaust and shake my head..... lolol
A lot of knowledge on here, so I get a lot of ideas.....
Keep them coming,.

the single outlet mk2 1.8 IS indeed larger than the mk1 toilet bowl. my GTI had ~2" all the way back from the toilet bowl.. but i changed it out for the dual manifold and d/p.. the increase in power was kinda amazing. didnt change anything besides the manifold/DP..

coulda been your DP.

I can barely change my own oil, and you throw this at me........ LOLOLOL
Though it is a nice addition to my 2009, I'm hoping to be happy with the Giles IP on the 89.

1)well others have done this and they made build threads. covered in the FAQ section. so your not the 1st one to do it and you can look at what they did.
2) this forums is a great resource with plenty of people who know that they are taking about and can help guide you.
3) google.com
its just like bolting on headers/manifolds but now you have some oil lines (feed and drain) that you have to hook up and a charge pipes (no IC) or more depending if you go with an SMIC/FMIC/AWIC.
its a good learning experience so you will no longer say that you can barley change you own oil

Thanks for the pat on the back, but it ain't happening. I have tried many,many times but my mechanical skills are piss poor. While it does help to have the right tools, I have no place to work, and can't spend money on nice tools I will probably never use. I should have spent my summers as a kid in a garage trying to learn cars instead of playing baseball all day. I didn't make it to the Yankees, either.
Even borrowing tools, it just ain't my thing. I have loved cars since 1964 (ok,maybe 1970) but the mechanical talent just is not there. Hell, trying to get my 1964 Checker running I burned some wires. So I'll save my pennies for a restorer. And not many LI guys here for a build party. Today's paper had the cost of living in the NYC area up 14% from last year. So I don't think anyone would have time for a build party or 2 anyway.
Before I got a good deal on a rebuilt engine, Tyler (BYM) offered to rebuild mine. Jokingly said it's crazy I could build a model airplane, but can't fix a car. Tyler can work wonders with a car, but couldn't build a model airplane..... :) Go figure. (His words, not mine...lol )
While it has been done, is it not recommended to run a turbo without squirters under the turbo? IIRC, the psi setting makes the difference, but I can be wrong (and probably am). And the oil squirters under the pistons make a big difference as well. I do recall people doing it with an N/A, but with limitiations.
My days of speed are over, I am into mpg and not mph, like many here, obviously. I was pretty content with my 52 hp N/A, but need more pep for the upper hills of NY State and the a**holes who drive around LI and NYC. So I think a Giles IP and a good exhaust or headers should suffice.
Of course if I was good with a wrench, I would have already had your turbo on.. :)
Again, thanks for the boost (pun intended), but Mr. Badwrench is content reading what you VW diesel guru's post and pics showing the work, and staying amazed.
Stay safe, stay well. Jimmy.
