hey im new to this forum. Im andrew and 19 years ago my dad decided to make a gud choice and buy himself a VW. (thank god) he bought a 1988 jetta TD. really really really reliable cant complain. 420 000kms and running great! just replaced the head gasket 2 times but thats wear n tear. belive it or not never changed the clutch with 3 drivers. me my dad n my brother. not 2 mention my brother and i lernt manual on that car.
Any ways my dad gave me the car cause i just love that car so damm much sorta like a brother to me. Anyway i love driving it i love the way it drives n i love shooting black smoke out in peoples faces. But its just not enough go!! I really love my TD but i need more power. can anyone help? i want to run my stock turbo and also dont want to spend to much money. VR6T project in mind for the futer. I no how to get alot of power of a gasoline engine but deisels not 2 sure. Please if u can give me sum advice id really apricate it.
By the way i decided to paint my car ill try posting up some pics. adding some smoked aero lights with the kamie spoiler. big bumper and m3 styled smoked tail lights. with afew of personal touches. BBs rms with 2 inch lips the list just goes on and on.

How much power do you want? If you are losing power that's one issue but if you want increase power that's another. Has a rebuild ever been done to it? This car has over 260k miles so it might be a little tired. Might be time to get some new parts. It's amazing how long these diesels last!! :D

i wouldn't go with a vr6 personally. fuel prices just dont justify it. plus the amount of cash you'd dump on a vr6 + turbo kit is just insane.
why not go with some diesel technology such as a PD150 engine? a lot of people are having good results with them, and i believe 300 hp is not unattainable. (with crazy amounts of low end tire screeching torque :twisted:)
now back to your power needs. check out the FAQ on how to make your diesel a faster car by SMOG. it is really quite simple... just takes time/money. intercooling IMO is essential. i bought a water spray kit, but haven't used it yet due to the fact that my car burns too much oil when i hit 20 psi on the turbo. yes... just increasing boost pressure + more fuel will definitely help you out, but the difference an intercooler makes is remarkable.
have you done all the regular maintenance on the vehicle such as flush coolant system every few years, bleed brakes, change fuel return lines? how's the pump running? did it ever leak on you? if it hasn't, be ready for a leaky surprise :shock:
good luck

First thing you can do is to open up the spaceship on top of the pump and rotate diapragm to maximise extra fuelling as turbo comes in. Sleeve on power screw can come off later... :wink:
-
the 17" rollers and things like spoilers and heavier bumpers will more than likely contribute to worse performance. i'd start by keeping the lighter parts if you're performance-oriented. beyond that, read up on DIY pump mods. or if you've got the green, the big one for these engines is a modified injection pump. the general opinion is that giles does good work. you'll drop around $1k, but those BBS with lips were likely no less than that! have fun :)
ps - read the posts on this forum, do a search. larger exhaust (at least 2.5" mandrel free-flow including downpipe), increase boost, etc

Howdy
I run a pretty highly tuned N/A VR in my B3 Passat--I enjoy it, but servicing the engine (early VRs demand loads of attention) and the crappy MPGs aren't fun (CR is bumped and reqires high octane fuel, Avg per tank of 24 mpgs--running hard, below 20 mpgs). This is not my daily driver, just too much of a PITA.
Fast yes. Sounds from the tail pipe--nothing beats a tuned 12V VR6!
But there are many Diesel VWs that dust my VR, and a few even run home brewed biodiesel (they claim price per gallons below 2 dollars US). VR swaps are old news, almost dime a dozen (seen some pretty crappy work out there too--its easy to muck them up).
If you have the money it would take to make a reliable VRT (the 02A trannies don't last too long, and without some sort of limited slip diff, first and second gear will spin your tires very easily. A kid on his Segway will beat you to the other side of the intersection.) keep the diesel a diesel, and get a VW with the VR installed from the factory to add the turbo to.
One less headache, and you'll have the diesel to get you around while you wait for VRT parts.

yeah ive had the engine rebuilt at 320 000 kms. and surpisingly no leaks ever. no joke this car runs beter than my dads new car witch i strongy hate. toyota camry god that car is ***. wtv told him 2 sell it and buy a mk4 jetta. And as for keeping things light im all with that. but no way im i ever rolling on 17" im no gangsta im a dubber 15"s lol.
As for the vr going in that car im not sure. i sorta feel bad taking the "heart" from that car n chaging it. And i sorta wanna have a daily driver thats reliable like my deisel. But the vr is defantly going in a mark 2. the way that thing goes and the sound is unbeatable. thats gonna be a life project lol. but i really wanna get my deisel to at least smoke an 16v at least. if im aiming for vr6 then might not do it at all lol. thanks for the help guys really gets me thinking if i wanna keep a deisel n boost it up
-
as for the spoiler thing hell no! only a gli one is on n staying on i dont wanna fly 2 space with the hondas

hehe everyone help me convince this guy to ditch the VR6 and embrace diesel!
unless you have a stage 5 turbo kit, the vr6 won't do squat vs some of the diesels out there. just remember that on a gasser your torque doesn't come on until way up in the rpm range. yea those commercials for listening to a honda redline at 8k rpm really makes me cream myself :roll: its more like quadrupling the fuel consumption and that really makes their cars look 'green'. then you have the diesels. they talk to you. you can hear them growl... and sometime whisper things like "feed me rice" or maybe that was a dream i had... but anyways, low end torque FTW!!!!!!!!
if your car is pushing 400 ft/lbs @ 2k rpm, and some dinky ricer is pushing 300 ft/lbs @ 6600 rpm but has more HP, who do you think will win off the line? sure if you want to win an all out top speed race with someone then go with the gasser and the high hp, but be prepared to get in big *** if you ever get caught racing. and if by chance you live in Ontario, you've heard of the new law where if you're caught doing 50 over the limit, they seize your car... :shock:

"hehe everyone help me convince this guy to ditch the VR6 and embrace diesel!"
All in good fun of course!
I have two VW buddies running MK2 VR conversions--one has a turbo w/IC. I love the speed--and the noise. Oh, sweet narrow angle vee--though the turbo really mutes the noise out the tailpipe. They spend a good deal of time wrenching (wiring seems to be a recurring issue) to keep these hybrids going (have other cars for daily drivers). There is a MK4 TDI around here that they have been spanked by, over and over. That Golf is SICK!
Both cars are not as much fun as their stock versions around the twisties--the VR is a HUGE, heavy lump of metal. Though the tuned MK2 TDs don't wind out to 7200-7600 RPM (like the VRs), they make some serious twist early, and once one is accostomed to the early upshifting routine, they kick arse! Less mass over the front wheels too, means better platform dynamics.
Hey, though, you sound young and its your oats you need to sew--I did mine. Just wish someone was around to show me the advantages of the diesel way, back then--though when I was getting into diesels in 83-84 there wasn't as much go fast stuff available--or the InterWeb. So gassers had me for a spell.
Check out what you can do to the TD--very cool options! And though I mostly lurk and learn here myself, I've been very impressed with the people who are willing to share their TD knowledge. Quite a good diesel community here.
Thing is, do something, which ever way you want to go--dreaming about it doesn't get you hands on training. And nothing beats hands on experience. You may have the talents to take a VR6 gasser and make it a TDI VR6!
Good Luck!

haha ye u deisel people are really cool. helped me out alot no joke. reading all ur comments really got me thinking bout making my deisel one of a kind.
And yeah i had a hard laugh at that honda add to. haha sorta though the same thing feed me rice lol.
and yes i am young. im only 17 have been working on mk2 jettas for most of my life lol. got 4 at my house now. my dads old deisel that he gave to me witch i love so much. my jetta flair 2 witch is a dialy driver intill my car is finish being painted in my garage. a project car me and my dad took on awhile back 91 jetta 8v witch was scraped in the front end and my bros golf.
im just confused on where i could pick up sum deisel parts. never really got into deisel tuning. never really though it could smoke a vr either. :D never though there was a tunring forum for it. wow deisels are really underrated to me. any one got sum vids to convice me 2 make my deisel fast and leave the vr alone?
oh as for the wireing on vrs on mk2s i no its hell! :evil:
-
NO i dont live in Ontario i live in the freanch part of canada lol. Quebec n yeah we got that law here 2 now :evil: Wont stop me from ripping it lol
-
check this. i have a PD130 with a nice VNT-25 i will be tuning into an mk2.
check out that golf rip! :twisted:
-
but what are the main thingsi can do 2 make it go faster? ive heard about the governor mod but lost the link to it. does that help? it said it makes it smoke less and makes it go faster. but what else ccan i do. boost controler,intercooler? is there more than that. i wanna at least have 150 whp. if possible.
-
There's no one, two, or three things you can do to a 1.6l diesel engine that was designed for 68 hp to get it to make a reliable 150 hp... so you're likely not going to get much response to your question.
Having said that, there are many many ideas on this forum that will get you closer and closer each time.... read read read here and www.vwdieselparts.com.
-
yeah but these people here are saying a 1.6TD can rip apart sum vr6s. wouldnt a td at least be able 2 make 150whp 2 catch up 2 a vr?
-
yes but not with a few quick changes. research and plan your attack, or pay someone to do that for you. all the info you need is searchable.
-
allright thanks dude i think ill do that. id really would like to keep that TD in there i just need it 2 have more zoom

As far as TD power (indirect injection, no computer, like your Jetta) is concerned--there is a MK2 Golf I see around here. The owner (Bill) claims 160hp at the wheels, with propane. So many folks boast about their numbers, so I don't know how accurate this is. This car beats my VR, every time, up to 65/70 mph.
Rennen Performance in Brunswick, Maine did the work on a local MK 4 TDI (direct injection with computer controls), and they claim a corrected chassis dyno figure of 200 hp and over 400 lbs tq--at the wheels. Daily driver. Power all the time, anytime (in the rev range). Monster twist!
My VR makes its power, starting at 3200 rpm--the TDs and TDIs I've driven are ready to shift up around there.
The VR has 20 headbolts (PITA) and requires 6 qts oil per change. The timing chains fail--even the updated single row design with the new style tensioner don't last too long if you hammer on it often (gotta pull the tranny to replace the chains). There are two coolant pumps--one is electric, and is pretty failure prone. Heads suffer from errosion/corrosion issues. The cooling system has quite a bit of plastic that cracks and fails (the VR runs VERY hot--my oil temps range from 220 to 260 with full synthetic oil) due to the high underhood temps. Coil packs (only early, and rare, 92/93 engines have a dizzy and a conventional VW coil) fail often on high rev-ers. Bolted to the side of the head, the heat makes them crack and fail. Etc.
I'm not saying the VR is crap, but from a service viewpoint, the inline 4 VW diesels are a JOY in comparison. And still, can kick arse!
Big fan of Quebec--and Montreal. I spend a few weeks each summer in Montreal/Mont Tremblanc.

You will never get up to 150whp without a hell of a lot of money. That doesn't mean you can't make a 1.6TD "feel" as fast as a VR6. A VNT15 adapted to run in that engine (you need to rig up a vnt actuator using a regular wastegate actuator or something along those lines as well as modify the downpipe to flange up to the VNT turbo), a simple, small intercooler, and a tweaked injection pump (Giles pump ideally) will make it "feel" as fast as a VR6 and you could probably smoke one (figuratively and literally) off the line in a short drag.

well i would have to say that 150 whp is definitely possible on a low budget.. the only real issue is reliability and longetivity. putting a huge intercooler, opening the exhaust, running 25 psi boost with tons of fuel, gov mod on pump, timing advance mod... that should run pretty close, but fuel mileage will suck, and you will likely be targeted by enforcement (because of the big soot cloud) and the engine won't last too long running it like that.
-
i still cant get it tthrew my head. lmao i really underestemated these diesels. beating a vr never though in my life a TD can smoke a vr in a short drag. 4 banger vs a 6. right now im thinking about FMIC nothing big. just so i get my exast temp. more cool. uhm also thinking bout a bigger exaust front to back and an electronic boost controler. What PSI u think i can be running wit out screwing up my connecting rods ect. dont diesles run at a higher temp then a gasser so cant mount the boost thaat that high. any way i just want sumthing reiable cause thats one reason why i love my vw i want it 2 have sum go and i dont wanna be pulled over by the cops cause of exesive soot. lol even tho i find it so funny shooting black smoke into peoples faces and cars. Espiecally honda civics :twisted: stupid ricers :twisted: can some one tell me more about the gov mod? ive heard people talk about it but not to sure what it does and why to do it. any ways u guys are really chill didnt expect this many people 2 write. thanks alot
-
and yeah mtl is pretty chill place 8) lol not bad here just hate winter :x yeah ive heard of all those problems about the vr espeacailly the timing chain. one of my buddies gots a 2.8L vr6 12v running a T3/T4 turbo on it and his timing chian keeps on screwing up. but it still not gonna change my mind. lol its not gonna be a everyday car anyway just a toy car.

FAQ has some topics on how to squeeze more power.
