MK2 VW Jetta Diesel: Giles Injection Pump Upgrade
Vložit
- čas přidán 3. 12. 2020
- This 1989 VW Jetta has a 1.6L non-turbo diesel engine. It is SLOW. Browsing the VW nerd forums, I found references to a guy named Giles who builds a more aggressive injection pump for these old diesels. My original pump was leaking so I decided to replace it with one of these performance builds. Here is the story of making a really slow car, just faster enough to be more fun.
It is still really slow.
Here is a link to Giles's shop: www.performancediesel.ca/
Before taking it out for acceleration tests, we replace the axles because they were making clunking noise indicating failed CV joints. - Auta a dopravní prostředky
I picked up one of these up in January and have been slowly fixing it up! Thanks for the extra motivation man!
Right on! The difference is remarkable. I just picked up a 1986 turbo diesel. I'm very interested to compare these two after the TD is sorted. Thanks for watching.
@@tr3wrench I hope you post some content of that one as well! Thanks for making the videos! Cheers man!
Hoping to get a giles pump for my 87 jetta coupe na automatic. Yup, a diesel with an 010 "TL" code automatic. Currently bone stock engine with the fuel screw turned in 1/8th turn and the cam advanced 2°. Actually fairly peppy for what it is. Going to attempt the governor mod first but pretty set on the giles pump. I've read the giles pump can add up to 20hp. Also the gti dual outlet downpipe makes a difference too. Going to port the exhaust side of the head, make a custom intake with velocity stacks. I currently get 1000kms per tank (55L). I'll be happy if I can see the 52hp bumped up to 75hp. Tq to maybe 100ft/lb? (Never see people talk about the tq number.) And 820-850kms per tank. Because it's a 3spd auto with final drive 1:1, it sits higher up in the rpms cruising on the highway at 100km/hr.(no tach so unsure of exact rpms) and I'm able to accelerate and pass people with ease at highway speeds.
I think the Giles pump is the best upgrade you can do to these. That said, the MF code turbo diesel is light years better. It AlMOST feels as quick as the 1.8 gassers of the day. Thanks for watching
Hello there the modified pump is very interesting, what would say, how much more PS or HP does she have and and do you think it's still as reliable as the old one (apart from the leaks)? Am I the only one where the internet site from Giles's shop is down?
Just checked the site performancediesel.ca/ works for me...
So far I am very impressed with the upgrade. The pump is a Bosch VE unit with modifications to the rate of fuel delivery. It is basically a rebuilt pump, with a bit of a performance add. I don't have hard numbers but I can say the car is much closer to it's gas counterpart than before. I took about a 5 MPG hit on the fuel burn, but SOOO worth it.
@@tr3wrench Thank's for the reply.
Sweet deal. Keeping it alive
Stay tuned. Plans for this one. Thanks for watching.
I have a 1981 Rabbit Diesel that has been in my family since new. I drove it in college, and my biggest complaint with it was the lack of power. It's interesting to see that the new pump basically shaves 4 seconds off the 0-60 times. Very impressive! How much did the pump cost?
I paid $1435 for the pump but that included a $350 core charge. I kept the original. I would say this is the best "speed" mod you can do to the VW NA Diesel. You do need to watch your temps. You are outside the design limits of the cooling system so you CAN overheat the car if you are running up hill on a hot day with the A/C going.
@@tr3wrench hello i have the same engine and i have a question about cold start mechanism of the pump, when you have it on can you hear the diference in the engine running? becouse i cant understund if it works or not, thanks
@@sk8foreal yes, it increases engine RPM by about 200-300. It is a cable attached to the pump at the bottom, left if facing the car from the front. The cable slides into a small hole and held in place with a set screw. The cable could just be sliding without pulling on the actual advance.

@@tr3wrench no the screw is ok, the wire its moving the lever fine, but i cant hear eny difference on the engine sound... it increases RPM in a warm engine to or only when its cold?
that money buys you 2 complete TDI engines with ECU and all the accessories 😎💪. Well the engine mounts will add another 4-500 USD/EUR and I understand that the tinkering involved is another league compared to a pump swap. not to mention keeping these cars original adds to their value and charm. 👌//I also keep my mk1 NA diesel engine original and detailed to crazy levels.
Truth! I was just trying to solve a leaky iP and I didn’t want to be down for an extended time.
Do you think you could have fixed your old pump leak without buying a new one? I have the same leak issue with my mk2 and am debating tying to fix the old one vs buying a new one.
....or just hitting up a junkyard
Yes Definitely! The previous owner had replaced all the seals in the pump to run a biodiesel mixture. He left detailed instructions and notes. I doubt I could have made the performance upgrade to the internals to match the Giles pump I purchased. IMHO the performance upgrade is worth the $$$.
better late than never. when filling the pump with diesel. Use one of those vacuum brake bleeders on the retur side of the pump saves a lot of cranking :)
Pro tip! Thanks!
Hello i have vw mk1 1.6 diesel and how it is possible to get that good results 0-60 is this same pump rebuild or somethink is diffrent as a upgrade inside...
Yes it is a performance shop that rebuilds them. I'm not sure of the exact upgrade but I've heard it described as "more aggressive timing." Probably a different cam or something in there. Thanks for watching.
Hello! I have a 1985 audi 80 b2 and its a 1.6 diesel no turbo and its really slow so i was thinking if new fuel injectors and a kind os your fuel pump would effect my 0-60
It absolutely would. Do be careful as it will produce more power than it was designed for. You can overcome the cooling system on really hot days, running the A/C, and pulling a hill at WOT. I have a coolant sensor and second gauge for the radiator inlet side.
@@tr3wrench what about only fuel injectors would that help it pull better w no problems
I don’t think so. Unless your injections are faulty, new ones shouldn’t make a performance difference.
nice video but I wish you would have talked more about timing the pump. That's where I have the problems.
Hey thanks for watching. I have an earlier video where I talk a bit more about the procedure.

Also here is a video that really helped me out when I did it for the first time.

Thinking about trying to find a 1.6 diesel to swap in my 1990 jetta gl with a blown 1.8 8v... just putt around and get like 40mpg sounds like a decent idea at this point in life haha
If you can find a turbo donor car (MF code)... DO THAT. The ME code is S L O W
@@tr3wrench Ya awhile back I had thought about going with a mk3 1.9 diesel maybe still the best option so it's not a complete turtle
@@tr3wrench I have a 2005 AWP 1.8t mounted in it now on g60 corrado mounts, but I'm in the beautiful state of California where it's basically impossible to register it with how the emissions evap system works on the mk4. But if I do a pre 1998 diesel swap the state basically doesn't care about the emissions
This is the swap! AHU/1Z would be brilliant
The original Bosch pump in the one pick looks like it has an air fuel aneroid for the turbo model.....it sits on the very top of the injection pump.......?
The after market hikes pump does look like the right one for the naturally aspirated model though
I actually contacted Giles when I got into this project because I had the same concern. That "contraption" on the top is an altitude compensation device. His build deletes that. I just put a plug on the Vac generator port for that application and good to go. The performance difference with this pump is remarkable.
@@tr3wrench interesting 🤔
How much?
I think 800 without a core. Less if you have a core to send him
@@tr3wrench Is the pump you took off a 1.6TD pump?
@@1975Kombi1 negative. It was the OG ME code pump. Still have it.
@@tr3wrench oddly I have never seen that style pump on any normally aspirated vw in my entire life and I have own dozens of mk1 and mk2 NA and turbo versions.
@@1975Kombi1 I personly think that it is just vw had some turbo pumps over and instead of buying na ones, they just bolted those on instead.
Great content but I find the music absolutely terrible.
Yeah that was a live track from a gig in the late 90's early 2000's. I try to use all my own content to avoid CZcams Jail. Some are much better than others....
