what is M-TDI?

[R.O.R-2.0]

breaker points are not fun, but they dont ever leave you guessing either. points usually work, or dont work.. and if they dont work, you clean them and they work again. lol..

and yes, those vacuum controlled carbs of the late 80s, yea, f#!% that.. ive taken miles of vacuum lines off toyotas, hondas, mitsubishis, and the like..

they always run better with less vacuum lines..

anyone remember the 3 barrel carb that hondas used to use back in the day? and that big black box they had to control the carb? there musta been 60 vacuum lines coming out of that control box..

I'm shuddering at the thought..  I had one..  And they needed most of the lines to run half decent..   When working, though, they did work rather well..

As I build up cars in my head I think the MTDI would be great for a straight show car where people love less engine bay parts and wiring clutter. Having done a couple tdi swaps I don't think the wiring is too bad but it typically requires the swapper to learn to read wiring diagrams which seems to be above 90% of the VW world's abilities

well, the car is a 2001 MR2 Spyder, and I was thinking of how I could avoid all of the CEL mess, so I would need the tdi to send sensory information to the ECU or use an tdi ecu and wiring harness instead.  I originally loved the idea of a completely non electronic car save the rad fans and fuel pump.  but I'm thinking more and more just going tdi, or MTDI I love the mech bosch pumps, mainly because I want to use a fully mechanical vnt turbo.

thank you to the gods of the forums combing

what of the prospects of getting one that has the VNT turbo (2000-2003 i think) and has the computer to control it.. possibility eh!

thank you to the gods of the forums combing

it was on the 1st page of the FAQ...I don't look too hard

[NintendoKD]

It has been a long time since I checked that thing "the faq".  I have been on the forums too long I think, have become too lax and lazy.   well, M-TDI sounds like the ticket to make the most power since I can use a mech pump and send it off to Jedi Master Giles.  the only catch is........ now I have to buy a TDI engine "not easy to come by" "NOT CHEAP!"  god help me, i'm in too deep.  TDI would be better in some ways because computer controlling gives much more finite tuning, and I have a friend in Germany who may be able to get me a suitable engine that may or may not be legally installed and used with or without proper emissions equipment.   I'm horribly torn now, to M-TDI? or to IDI?  High power to weight ratio and the "nobody has done that" factor are my initial  reasons for looking into it.  I still think that there is some juice to be squeezed out of the old orange of the IDI but the ease and uncomplication of the TDI sound so darn alluring.  It also doesn't help my descicion that I just made some deployment money from being here in Afghan.  All in all, this forum is bad for me, like vegas to a chronic gambler.  I think I'll just cut my losses and make 2 MR2's with both engines built to the teeth. HA! TAKE THAT!........    thanks again guys

I vote you to show me what an IDI is capable of. TDI can be your next one...they will be around longer anyhow, so build the IDI now while you still can. <begging and pleading voice if you can imagine, they need a text for that.

[R.O.R-2.0]

IDI - capable of 200-250 hp

TDI - capable of 300+hp..

[blackdogvan]

I think numbers based on what you can get out of stock internals & still be daily drivable would be a better more real world discussion.  (not including clutch)

TDI e or m - larger turbo, IC & tune - 200hp & 300ftlb ??

AAZ IDI -  larger turbo, IC & tune - 150 & 220ftlb  ??

1.6 IDI - similar to AAZ potential ??

Those are numbers off the top of my head, what does the collective think?

[8v-of-fury]

Stock TDI should handle just a tune with no issues. Few guys over on the TDIclub running at least 200ft.lbs on stock internals.


The main limiting factor with the TDI's is the injectors. The only difference between the 90hp 1Z/AHU and the higher hp motors is the injectors. A set of .205 injectors in the same motor will increase power to like 120hp/185tq. A set of .216's will bump that again 135hp/210tq. All with stock tune, stock boost, stock everything. To be able to gain %50 hp and %35 tq with one single modification... incredible. Add a tune to that to make it boost sooner, allow more boost to be made for the extra fuel, and adjust timing! your making some power now.
