well i was gonna buy the rings them selves and then have my machinist here in ny do the machining. I was not going to ship my block or head to them..for a idi i would do a block groove fro the tdi i would try to do a block and head groove. i would not use acopper headgasket on teh street i would fro a race car but teh water leaks would driv me nots on teh street ..if it did leak..
thanks

For the fire ring, i was talking about my 1.6TD, not my TDI. The new project is an 1.6TD engine.. so i want to get it fire ring. But do you think that only groove the block will ne enough, and will it seal correctly and the ring will sit on the prechamber ?

The next problem will be, how much deep and what`s the size of the groove we need ? It should have some tight measures to get.. Perhaps Haisley can provide with the ring, the spec of the groove we need ? I don't want to experiment much on this way, i don't have many engine block to test..

I would say try to blow a 1.9headgasket with studs first. I've had no luck. Its far cheaper than fire ringing or o ringing. Also deo where are you getting 12mm pump heads for these pumps and where/what di cam plate are you running?

RedRotors · « **Reply #18 on:** November 01, 2005, 10:58:00 am »

Im gonna try this first ( 1.9 gasket ) i was just worry about the dead space due to the over boring. Im gonna run a 12mm pump with a lot of boost. And once the 12mm will be test, i`ll switch to bigger custom head :twisted:

Deo, have you tried the DI camplate on the IDI engine ? If yes, how the engine react ? The ramp is a lot more aggressive on a DI plate than a IDI, so im a little worry about the combustion issue..

Don't worry about the dead space, allt he headgaskets I do now no matter what on idi's are 1.9 gaskets. 2 of the most recent ones I have done are running 35psi, the other one 20 psi, nothing has blown yet. If you want a head put a 1.9 head on there, you won't regret it. Also if you need some portmatching/polishing or some radical headwork with deck mod like malones let me know.

i did and will be again using a di cam plate in the 1.6L it worked great only problem was the regular dial indicator did not extend llong enough to use it to time the pump last time. so i had to guess time it then..as you said the ramp is much bigger and has a deeper "pit" to bottom the dial indicator on...i think i will have that solved this time a s friend here diesel tech ..he is letting me use a differnt dial indicator with LONG throw so i should be able to time it liek a normal vw diesel.....as for the source of my 12mm plungers i had bought two complet 4bt cummins ve pumps years ago and i used on head on a 1.6Ltd pump ..actually i sent both teh 1.6TD pump and 1 of the 4 bts to piers in bc told him to make the most extreme pump with the combo of both pumps..so it has the 12mm plunger and di cam plate etc....so now i have aconverted 1.6td pumpand 1 complete 4bt 12mm pump..so i plan on using to other complete large shaft 4bt pump on my mech tdi..i will just need to mod the govenor spring...anyhow i hope your right about the 1.9L headgasket....i hope it doesn't blow i always blow em under the water outlet on the side of the head. literally blows em straight out.

I'm actually doing something similar. I have a new cummins 4B pump so I'd like to use the whole thing as it has the new vane pump and everything. It also has a big input shaft. The cam plate is pretty aggressive as it is for DI. Here is a comparison picture:

I ripped it apart because I didn't want to use the Cummins timing advance piston as there is no cold start provision. It also has no LDA, so I was going to add one off of a Peugeot pump I have sitting around. I also have a MK2 NA pump that I'm going to take the linkage peices, as well as the 2 detent timing advance/idle adjustment linkage off of. I wouldn't mind finding a 1.9TD cam plate but I guess I'll work with what I've got so far. Oh, I also couldn't use the internal linkage with the peugeot pump top so I swapped in the Peugeot linkage. I'm thinking about going to a 1.9 though so I haven't decided when I might put this pump on the car.

This will dimensionally fit in the 1.6 bracket (I think - haven't tried) but the concern I have is with the offset of the 1.9 pump. Can I use the 1.6 bracket on the 1.9 engine and keep the 1.6 pump offset?

As i can see, the cummins camplate seems to have a less agressive ramp than a VW TDI.. The VWtdi raach the top faster than the Cummins one. I should think that the cummins can works better than the VW tdi one..

Dave, you've mentioned a couple of times that you don't have any probs when using the 1.9 head gasket on a 1.6 mechanical head. How are you blocking the extra hole in the gasket?

935racer · « **Reply #24 on:** January 23, 2006, 06:31:23 pm »

No I've only done it on the hydro heads, I am gonna figure something out whenever my friends solid lifter HG starts to leak though. Its funny i have changed about 20 HG's (no joke) in the last few months that I started using the 1.9 headgaskets and none that have come in have been solid lifter. Malone just told me he is bringing in a solid lifter engine soon though so looks like I will have some news in the next couple weeks. I'll let everyone know as soon as it shows up.

vph · « **Reply #25 on:** January 23, 2006, 07:39:41 pm »

Ahhh, I made an assumption there on the mechanical head part. What do you all think about getting a spare gasket and cutting a piece out? That would be expensive but just thinking about expansion rates and the like.

Re:4BT Pump/Mechanical injected TDI
there is a guy who recently joined the yahoo samurai diesel list who mods the governor of the 4BT to run the 1.9TDI - it requires a custom drive pulley from what I understand, and you're good to go. Big 12mm piston, I gather. He says you can get a modded brand new 4Bt pump from him for $1500 U.S - He also offers a hybrid but says it's only safe with stock hp, so I would guess he uses a 1.9TD and just mods it for more pressure? And it's only $600 US from him.

I have come across www.ultim8vw.com - which is a guy looking to import European TDI motors for extremely good prices (at least compared to what else I have seen) This makes me think ahead to if/when I kill my 1.9td (I drive under water sometimes) that I'd like the next engine to be a built 1.9TDI. The European end is in Czhechoslovakia - where it seems they like racing diesels. They have electronic pumps, with a harness, or they offer a mechanical hybrid of some sort, from what I gather they need a 1.9TD pump and put the lower end of a 1.9TDI in it/under it somehow. If it has the big shaft and cam of the TDI, with the controls of the 1.9td on it (maybe the 1.9td Euro aneroid is more like the 1.6td version here ). I think. Anyway, they say they can do a Mechanical TDI pump for about $500 if you buy a TDI for like $2300 (I should go back an check all these numbers ) - but I am more interested in opinions on running TDI engines with mechanical pumps. - does this seem like there might be one that would hold up? I'd like to see a peak hp in the low 200's - or maybe more ........

:twisted:

thanks for the link there is another czech dismantler that does business on the vortex... we need to find a mexican dismantler as they get some cool tdis too.. I'm trying to source a 2.5 5cyl TDI and 6speed manual eurovan conversion..trying to get the 4wd / syncro stuff for it too..as supposedly the fwd eurovans undercarriage is already 4wd ready just bolt up the 4wd stuff and go .. my eurovan is 2003 with 24v vr6 and auto..it drinks gas..argh...ha go from passat tdi to vr6 auto eurovan haha..huge huge diffenrance in mpg..but if i can convert i have heard the 2.5tdi eurovans pull down 35 mpg or so......any how i want to know more about your sammy!....what mph can you run on teh highway?..and what mpg do you get?..my brother had a few and i had soem i was keeping for a diesel swap but i junked it still looking for a clean one to do though...my brotehrs would onely do about 65mph reved out with the gasser and 31" tires..
later

Give ultim8vw an email - he's got some cut-throat prices. He sasy he can source all that stuff -Syncro parts, the tunnel, custom transmissions, all of it.

I have even be working for him as an on-line tech assist - just started yesterday, actually - I'm not a VW tech, but I have an AA degree in Automotive and 5 years in a dealership before I got sick of flat rate

plus I have been messing with my 1.9td Zuk for about ....7 years - geeze I am getting old. I was thinking 5.

Performance - stock gears, 31's, a little too deep gearing for the 1.9td, with the little k14 turbo. I ran it with no pump mods, and while it was a little warm-running (still had a Suzuki Radiator) it hauled butt, 80 was pretty easy.

Upped the tires to 35" Baja Claws - I chickened out at 90mph, but that was fear of cops on the busy highway. I dd'd it, and at 65-70 mph I was getting 27-28 mpg on the highway - 45 miles highway, 12 miles city, in that commute.
