MK1 Cabby 1.8 G60TSI Buildup Phase 1 (R&D)

Termite's MK1 Cabby 1.8 G60TSI Buildup
FYI: I have started building This site as a diary to all my projects.
PHASE 1 (Research and Development)
So, it starts... I've told a few people about my plans. I was originally going to keep it a secret, but as I dug into the scenarios I came to realize I'm going to need some advice. I’ve started picking apart some brains and websites; even started hording random parts. I'm in the R&D stage for my 1.8 TG60 cabby build.
The Basics: Background of the VW 1.4 TSI
In series is the way the 1.4 TSI Golf was designed, but that could present an issue with hot compressed air going in to the turbo. I'd need not only an IC after the turbo, before the intake, but I'd like to put an IC between the charger and turbo if I am going to do this.

Parallel was my first thought, since I wouldn't be running hot air in to the turbo, and wouldn't require two IC's. So it's either two smaller IC's or one large one. I'll play this by ear as I go. Space and placement may dictate this design.
Of course, this concept isn’t new or different by any means at all. Lancia had a similar setup in their AWD Mid Engine Deltas and were banned from the races for having too much power. I believe a few other manufacturers dabbled with this concept as well, but I haven’t dug that deep in to them. Honestly, the Lancia engine is what originally spawned this idea in my head. That and I saw some Skyline with it YEARS ago. I was fascinated from that point on. That and muh boy DuncMan brought it up in conversation again one day. It almost seemed fait for me to try this…
“Why use an 1.8 8v G60 as your baseline.”
Simple, the engine was free, and readily available. That and I figured a VR6 is much heavier, less ground clearance, and I didn’t get one for free. Don’t get me wrong, the VR6 is hella sexy sounding, and backs a huge punch in the pants, but I’m going to stick with the smaller engine to start. It was suggested to me by CanaryRadoG60 (not sure his vortex name), on the Strictly European Autosport forums to go with a 16v conversion for extra flow. Thanks for the advice mate, I’m going to look in to acquiring the parts.
Asking for a handout:
Now, I'd like to pick the brains of anyone who wishes to support my cause. If you have ANY input good or bad, please send it my way. Criticism, constructive or not, will give me something to work with. The whole point of this project is to attempt to do something "different", something hard to do. Hell, I may even attempt to find seal and hose kits for this to take E85. The thought of a green performance car had crossed my mind.
The Scientific Method Who remembers this from school?
================================================
Problem
What turbo to use? I’m a bit new to the forced induction world, and don’t know the reviews and names of all the good turbo systems out there. I learn fast thought.

Hypothesis:
Test & Analysis:
Conclusion:

================================================
Problem
Stock G60 ECU re-chipping/reprogramming, MegaSquirt, other piggyback system, or standalone?
Hypothesis:
The ECU that came with this engine is from an automatic setup. I’m assuming this will work fine, but I wonder what using an auto ECU will do when running a manual. I assume the only difference is the auto ECU has kick-down control. Speaking of which, I need to sell that tranny soonish.
Advice from others
From CanaryRadoG60 on the Strictly European Autosport forums
snstuning.com <---sam knows his **** when it comes to all digi set-ups sam might have some info on the set-up you are looking to tackle. he might have tried and or thought of this one as well. sam might be difficult to get ahold of, but he responds well to IM on the vortex. look up his screen name.
Test & Analysis:
Conclusion:

================================================
Problem
Speaking of trannies... I also don't plan on converting the car to run the hydraulic tranny that mates with the G60, I planned on rebuilding and using my solid shift bunny tranny.
Hypothesis:
Of course I'll look in to changing the internals if I plan on producing an extreme amount of power. The bolt up should be direct as far as I have found otherwise... (Anyone?) I think the last owner of the cabby put a diesel tranny in it by mistake anyway. They said the old one went out on them and they had one put in from another car. Thing is, at around 65mph on the (120mph max) cluster, I'm actually rolling along around 40 something. That coincidently enough is about the same spot as about 45 or near there is on a diesel (85mph max) cluster. Either they put the wrong speedo in, or I have a diesel gearing. I am going to have to crawl under there or wait til I pull the stock motor out to check the stamping. If it is a diesel tranny, I might be able to get away without changing out the gears huh? Thoughts?
Test & Analysis:
Conclusion:

================================================
Problem
What about the Control Bypass Valve? [see diagram above] What do I use for that?
Hypothesis:
(order the one from the 1.4 TSI and modify it to work here?) Fabricate my own? How do I control it?
Test & Analysis:
Conclusion:

================================================
Problem
What is my boost mapping going to look like for a setup like this?
Is that going to be complicated or just based on overall boost?
Hypothesis:
Test & Analysis:
Conclusion:

================================================
Problem
E85
Hypothesis:
Might not work too well… It has been suggested to me that 18psi is the “safest” to run on pump gas, without detonation. E85 might not be able to meet that requirement.
Test & Analysis:
Conclusion:

- Green Earth Technologies for green motor lubricant and cleaners
- Green Filter USA Lifetime warranty vs. K&N's million mile warranty. Well I know that's a stretch, but meh... K&N also over dips their rubber edge seal, blocking more of the breather area. While most of the Green's I have seen are nicely clean and not spilling over in to the breather area. Just a small OCD thing I noticed.
- What ever happened with these "Green Tires" I wonder?
- Squire's Rear Mount Turbo Systems The external mounting of this system helps to cool the turbo and keep the hot air out of the engine bay. Plus the metal hosing acts as an IC, cooling the air as it passes through the externally cooled piping. This system also reduces turbo lag, almost making my charger setup null.

Stuff already acquired...
The Basics:
- The car: 1984 Cabby

- The engine: Stock 1.8 G60 well technically it doesn’t have the charger on it atm, so I guess we will call it a forged 1.8 (to be rebuilt fully and turbo added)
- The wheels: 13" 2-piece Ronal basket weave (don't remember the exact model) Boy, do I need to clean those!

- G60 stock IC
- Working stock A/C (yup I'm going performance and cool - suck it)
Extras acquired:
- GT Grant Mahogany
- New Duckbill (old one has cornering rash)
- Some seemingly custom One-of-a-kind tubular steel bumpers I pulled off this other rabbit I bought cheap in Baltimore

- PIAA HID ballast kit (not sure what I'm going to do with this, since I don't have a housing to use it with properly)
- HELLA OE flat lens headlight housing
- Kamei Factory OE Hood Scoupe (ahhhh fresh cabin air!!!) Used to belong to aKaBigMike, then acquired at Benbuilt4u’s shop. No Burkee, you still can’t have it back!

Planned to acquire:
- Turbo of course (but what kind, what size, blah)
- Roots Charger (the engine I got was just a 60 basically, it didn't have the G-ladder charger with it, just the brackets and everything else.)
- Hosing will more than likely be supplied by Henry's Engineering in Maryland. They are one of the East Coast's Leading manufacturers and resellers of Aeroquip high pressure hosing and fittings. A long time family friend owns the place, another long time family friend works there, as well as my Dad works there... can you say HOOK-UPS!?
- Flowmaster 44 Series Muffler 2.5" for that DEEP tone and high flow. (3" won't fit up and over the rear u-arm, unless I get REALLY creative with the body and cutting some channels.)
- Flowmaster Hushpower II Resonator 2.5" to reduce that rasp and enhanced the 44 Series deep rich sound. (3" won't fit up and over the rear u-arm, unless I get REALLY creative with the body and cutting some channels.)
- Where the hell can I score a syncro/4motion/quattro drive train for this damn thing? Yea, I kind of have dreams to add this to the list as well, but that's a BIG dream. AWD cabby!?- I'll add more as I think of it...
- Thinking about getting air temp sensors/gauges for each section of induction hosing, as well as just inside the intake opening; to monitor air temp as it travels the hosing. This might help me improve the heating issues stated above.

- If I go with opting to not use the Stock ECU, and use a stand-alone instead, then the carputer will monitor that systems software, and Vag-Com is a moot point.

Good Luck on your project, using the VW TSI as the basis for the hardwear will be the way to go. The most diffucult part will be the tuning of course. Keep us posted on your progress!

E85 is a scam, thinking it is "Green" is not a good reason to use it...

E85 has an octane of ~ 105 which means it would resist detonation better than pump gas which has an octane rating of ~ 87-93... Not to mention there are other ways of reducing detonation like alcohol injection, and lowering the C.R. more

That would certainly require me running a standalone on this setup then, yes? Man, that's a thought though... Not sure that would mate with this block though. I guess I need to also look up the bolt pattern and oil/water channel locations to see if they match. Man, I think you just cost me another million dollars and year of work.

Agreed, but it looks good at tax time. http://****************.com/smile/emthup.gif I doubt I'm going to go that route anyway. Was more of just an added thought really.

I didn't have a chance to read your entire thread yet, but have you seen Rokka's 1.8TG60?
I saw you are going to use the 020 trans. I have to say, that is suicidal...

Oh, he's already done it! Nice! I'm going to hit him up for some advice. Thing I saw though was, he apparently has his charger running always and dragging the engine down. I plan on using the electro-magnetic clutch method to disengage the charger. I don't want to have to rebuild every 3K like he is either.
Yea, I'm still not sure what I'm going to do about the tranny, maybe I'll talk to Rokka. His setup looks nice though. Good lookin' out! http://****************.com/smile/emthup.gif

Re: MK1 Cabby 1.8 TG60 (termitesgraffix)

I am not sure where his orig build thread was, but I thought he was using some sort of a viscous coupling for the charger. ...unless that was one of my bad dreams of me thinking how I will be able to rev my 2L20v G60 to 8500 RPM

Re: MK1 Cabby 1.8 TG60 (termitesgraffix)

dale don't run a 20v head. 16v is fine and much cheaper and you'll make great ph.
I've got a few cents to throw into the cookie jar.
Second problem. The TSI uses a magnetic clutch on the supercharger to disengage it for when the turbo is spooled. Finding a pulley that can adequately handle the torque/power required by the supercharger will be a problem. Mercedes might have something that would work but you'll run into belt compatibility and diameter problems.
Realistically the TSI setup is used for a blower to spool up a turbo that would otherwise have significant lag on the setup. The 1.4TSI without a blower would have poor turbo response, but you're building a 1.8 so the turbo you can use is going to be much bigger. I would say at the least something like a GT28R. You could save some money and get a T3 super 60 or something, they'll have worse boost response but that wont matter much with a blower to spool it up. Something in the 250hp range would suit you nicely I think. Still, probably past upper limit for an 020 transmission with any chance of reliability.
I would also advise against E85 because it throws lots of problems into the equation that will make life really difficult. Also as a personal opinion from what I have researched about it, it's not as green as you'd like to think it is.
You're going to need something with significantly more sophistication than a G60 ECU. It simply doesn't have enough programmable outputs to control everything that needs controlling.
Boost mapping: Basically you'll have the blower run up to a set RPM and disengage. The manifold pressure there will be dictated by blower drive speed. After that, the ECU/wastegate will control manifold pressure for the turbo.

Re: MK1 Cabby 1.8 TG60 (RipCity Euros)

yeah he stated a roots type at the top. Im planning on doing the same thing with my vr. im looking at the eatons and Im getting mixed reviews as to which supercharger I must use. I have a GT40R that I hope I can use without possibly overpowering the supercharger. I would also recommend water/meth injection when running this.

Re: MK1 Cabby 1.8 TG60 (rosecityromper)

and about the clutch if you see the diagrams on the TSI, you can see that it uses a centrifugal charger, which spins much faster than a roots type. do you think the clutch could manage an eaton as he stated he would use?
All good points. I was thinking of using the clutch from the 1.4 TSI, if it was able to handle the same RPM and torque for the charger I would use. Another thought that came to mind was altering an A/C clutch pulley. Pulley ratios could easily be offset by the mated block-side pulley. The clutch pulley will be mounted at the block, and the charger will have a standard pulley. I will offset the clutch pulleys size with a larger or smaller charger pulley. Blah, I think I got a bit redundant there... Anyway, thanks for the advice. Well taken.
Everyone has been downing the 020, and I don't blame them. Question is, what should I use then? Or should I just keep the 020 but find some place that will just replace the gears with heavier sets? I haven't even started to think about gear ratios to power band yet at ALL!

Re: (termitesgraffix)

I think if your gonna drop the money into this project anyway, expect to spend a little more on a cable shift conversion. O2J.

The charger doesnt spool the turbo on a twin charged motor.
