can you guys set us novices up with info on the different turbos and there characteristics??

To go with that, what down pipe works the best with each? Where do we get a bigger one??

ive got a stock system with a garrett turbo. i would like faster spool up. Would a smaller turbo be better? I know bigger exhaust would help. I put a small "boost leak" in the line from turbo to wastegate. Ive gotten my boost up to 12-13 vs stock 9psi that its been. Is this a bad idea? i think i will make one of those MBC's in the future.

thanks and keep up the great info. When i get brave enuf i want to attempt the govenor mod. Im trying to get a little more low end snap. Im not trying to kill my milage so my mods are small. Economy is still a big factor.

Garrett GT-15 turbo (or KKK K03) gives really quick spool and has flow headroom to support 20 PSI of boost all the way to redline (don't ask how I know

). The K03 was installed in the very latest AAZ turbo-Diesels, and can be adapted into earlier models.

An intercooler would be considered an indispensable complement to a turbo swap.

would a Ko3S from a gasser 1.8t work on a diesel?

In a word, no. Both the compressor and turbine A/R would be completely out to lunch for a diesel. The only thing they have in common is the bearing cartridge.

what would be a cheap intercooler to use for a turbo on a A2 Jetta???

Anyone know what the stock garrett was on an A2?

i only need up to 14psi of boost.
i wouldnt feel comfortable going more than that (14psi) so a smaller turbo would work good for me (maybe 12psi tops)

Then get a Garrett GT-15, and an intercooler you can find from almost any yard for an Audi 5000, Saab 900(0), Ford Thunderbird SVO, etc., etc.

even a stock 1.8t IC would be OK I would think, I think it's 6X6X4, so it's kinda small but it's really THICK as far as IC's go and it does a over all good job. Worked great for me with 23PSI all day long, except on 80F+ days when I was on the pedal hard. I'm sure you could find one pretty cheap if you look around on the VW gasser forums like 20vturbo.com or vwvortex.com (personally not a big fan of) and find some one that has an upgraded IC and go from there.

Mits. Starions had a nice stock IC also if you could find one of those.

Does anyone make a high flow downpipe/exhaust for 1.6TDs? I haven't seen any around...

ejust · « **Reply #8 on:** May 11, 2005, 10:09:26 pm »

everyone talks about them yet no one ever produces one....hmmm...

i can see why a bigger downpipe would be needed as the stock 1.6L narrows down from turbo to front pipe which makes no sence.

I take it theres no chance for the average guy to get one? bunch of us would like to know if anyone has ideas. thanks

I would THINK that if you contacted someone like Techtonics Tuning and had a group buy of about 20 people I'm sure that they would fab one up. But you gotta make it worth their while.

I know this has worked before for SEVERAL forums VW and Non-VW, it doesn't hurt to try right?

Anyone else interested? What kind of termination would you guys like to see? Junk the toilet bowl and maybe put a flex joint and flange on it, terminating under the car once hit hits horizontal? Maybe a slip joint in the middle to make it easier to add/remove?

I am hoping to have the design for Downpipes finalized by end of May early June. I am still away with a busted transimission, and have a big contract coming in, all of which are slowing this down. Pricing as of right now is looking to be $150.00 Cdn + shipping. This may change b4 finanlizing. They will be 2.5" mandrel bent, mild steel. If there is enough of a demand I will look at doing a SS version though expect it to be much more expensive. Once we have the initial design I will take custom orders (TD's in other vehicals, different turbo's ect...) I am not looking to make much for a profit on these, I just want to help out the comunity. That being said there may be some waits for Downpipes at certian times of the year, when we are busy with the contracts that keep us in business. As for pics, there are some pics of Mark's "Malone" downpipe which is a beta version of what will be released. Stay tuned

Sweet! Keep us posted!

I have the puny NA exhaust from my originally NA diesel Jetta with my 1.6TD engine in there, so I'm *really* plugged up...er...I mean my car is... :-)

So DVST8R, any word on those downpipes?

DVST8R · « **Reply #14 on:** June 06, 2005, 07:29:49 pm »

I just recently got home from a LONG trip, way longer then expected, like 3 weeks longer. Anyway I had to leave my car in alberta, due to unforseen circumstances. As a resualt of being away for so long, I have a mountian of work to catch up on. So the downpipes have been put on hold for a month or so. I have the beta design down, and a bunch of flanges cut, I just need to make a few minor adjustments and setup a jig. If anybody wants to try building there own I will sell the flange seprately PM me for info.
