1.8 8v turbo technics HELLLLLLLP please

Ha all the way on to the back of an aa truck if your mix is lean ( which it is top end) or to the curb when ya boost pipe pops off! Sorry been in both situations a number of times and got fed up being cut to shreds on the injector lines!

Nice, like that a lot.  If i had a spare car, i would have something just like that !

But looks like a MK2 rocker cover, mk2 inlet manifold, mk2 overun valve, Mk2 Throttle body (you can see the top where the throttle cable goes is more like a audi / 16v housing. so is that a G60 lump with the TT Parts added ?

DMArk - might be a good option to you if you dont mind loosing the originality and as MK!Turbo says Old skool tuning, unfortunately mines too original to warrant going this route, but i'm sure i would do if i had the chance.

PS: Mine can be driven how it should be if i wanted to   - but i;m too old now to drive it like that - that's what my new cars for  

each to there own.

Exactly MK1Turbo.

My AA membership will get me home (although its hasnt gone bang for 100,000 miles on k-jet yet   )

no its still standard mk1 8v block with original pistons machined to lower comp, standard mk1 head just machined all manufacturing marks off and polished, g60 gasket, g60 manifold (no 5th injector needed), 16v throttle bod with homemade cable routing and tps mount, 98 passat metal fuel rail with 330cc injtrs and re routed fuel lines, half a distributor  to run the oil pump and a 106 coil pack in its place  also has cps on custom bracket and 3bar map sensor, intake temp sensor,lambda sensor and a few bits more.   i know its not original tuning but in a way it is just with a more upto date twist its still the orignal engine underneath but it does 30mpg instead of the tt's 17mpg. i have been doing a 100 mile round trip every day to work for 8 months so it does help.

100,00 your lucky i didnt have the right dizzy or metering head and as we know they are impossible to find, so after a couple of detonations and heart ache i had to find a different approach and didnt want a 20v so this is the path i took. if you are looking for imformation on the tt kits ask to speak to dave at interpro in thornbury he fitted alot of these kits in the 80s and still has alot of paperwork etc on what was what , he knows it like the back of his hand and is very helpful and friendly sorry for the aa comment !

Very nice shopping list. Think i would have had to sell my gran to afford it. (she's worth her weight in gold If she ever reads this lol)
Mind you if the tt metering head is worth that much i could always sell that lol.

In your position i can understand going down that route, but nowadays it would be heartbreaking to see someone dismantle a genuine tt kitted mk1 just to try and get more hp.

Get it running right and enjoy the fact that you have a very rare little beast.

Many 20vt etc not as many G60 turboed Mk1 but very very few Turbo Technics Mk1s.

I think Turbtechnicsmk1 is the only original one that has come out of this conversation. Mine is running a mk2 inlet so thats not original.

Mine would have lasted longer than 100,000 but i did what most people no doubt do and gave it to a specialist to look after. They were special all right - didnt have a clue!!! so ended up rebuilding it from scratch myself. Its been fine ever since. As they say you want a job doing properly do it yourself, although we are talking the 90's here so things no doubt have changed in the time. Lots of time with turbo technics getting info, them testing things for me, checking pistons when i had detonation issues, disi curves etc etc to make sure the kit was all good.

Can understand your route Alan if the kit is that hard to get, i'm fortunate to have owned it for a long time so know its all correct.

I (and i believe MK1turbo) know Interpro - we had a rolling road shoot out with them when GolfExtreme was around (there's that age thing again!!), but the guys that looked after us weren't too upto speed on the TT back then.

Another option for fueling has always been a Saab turbo metering head or the volvo ones, as they were CIS and could sense boost - finding one of those might be an idea for DMArk.

DMArk - looks like we've gone off topic and highjacked his thread - we should bear this in mind. Perhaps start a new thread to do the Old V's new methods ? Be a shame to not keep chatting this stuff thru  :wink:, but lets try and help DMark in his quest to get his car running, so sure he will appreciate any ideas, perhaps cheaper ones ? as the poor chap has alreasdy started sticking his hand in his pocket  :cry:

Very True.
So dmark where have you got to today?
Did start looking at G60 piston sizes. You might be just as well getting a G60 bottom end to lower the comp as they seem to be pretty cheap.

i'll let you all know todays progress in a bit been stupidly busy today fixing customers cars ( how selfish of them lol) good results so far tho  

Hi,

Slight deviation but if any one has the info for these engines can they put it on the other thread I started ?

It would be great to get an idea of Power, torque, boost, timing etc etc to use as a base line when setting up these rare beasts.
 :twisted:

so…… yesterdays progress:
had a buthchers at the pistons they appear to have been machined as they have no raised half moon shaped bit at the back of the crown
set ign timing to 28 deg btdc w/o vac, set fuelling to around 4% co at idle when warm
i replaced the boost t for a straight pipe from turbo to actuator and it wouldn't boost at all so swapped them back over and it now works perfect, presuming the springs in the new actuator are too weak, boost is at 13 psi with no det or pinking or any real noticeable problems to be fair    the only problem i now have is with it being a carb fuel tank, when you put the car under load or go round a bend sharply it coughs as if no fuel , but in a straight line it's just perfect well quite awesome really also swapped the metering head bellows for a standard one this also appears to have helped.
the only thing that worrys me is if it is detting at top end and i can't hear it, all original problems have gone tho!!
other things on my mind are the clutch, which best suits my application, and what grade oil ie something around 10w40 or thicker??
oooh forgot to mention new injectors are now in and i've re-connected the little valve in the vac advance line.
have also checked part numbers on the metering head and they cross refer to it being a 1600 metering head, the plunger in the bottom of the metering head is quite a bit larger in daimeter than a std 1800 gti one tho.
with regards to the metering head there is a porsche 924 turbo one on e bay would this be ok for my lump or would it over fuel as i think the 924 turbo is a 2.5 as opposed to a 1.8
p.s. loving the hijacked post tho    and the pics guys

todays progress being: cylinder head removed to do gasket and some general inspection work, found that the pistons aren't standard gti and appear to have been machined and shorter rods fitted?
cylinder head is cracked between vales :?  not sure if this is gonna be a problem tho coz i've seen this a lot on deisels and it's never been a problem. now the inlet valves appear to be bigger (40mm diameter)
bore size is 81mm, the dish in the top of the pisons are 4mm deep as is the drop from the piston crown to the top of the block

DMArk - good news there my friend.
quuick reply before i fly out the door.
Pictons - yep they look right. Bowls cenatrlised and lip removed.
Cracking between valves, common on GTI lumps - had this on a 1.6GTI head. reckon its because they leave so little space between valves. Never created any problems for me in the past on other engines. If its not causing any issues i wouldn;t worry about it.

I'm away to break a 924 Turbo, the engine is a 2.0, not sure if this helps as I have no idea if it's compatible with the 1.8 tt :dontknow:

slightly random question but i have a new fast road cam knocking around would this work on a turbo application????

another stupid question: can i replace the solid/shim lifters with hydraulic ones??

Hiya , I run a standard cam , I was told that lumpier cams can have a negative effect on turbo cars due to valve opening times being longer , I'm not saying you can't get uprated cams for tc cars but they are different to na car cams

cheers alanh, didn't think it would be any good just thought i'd get a second opinion   i'll be putting on here for sale today at some point, it's a piper 276 i think.
as for the solid/hydraulic lifter thing yesterday i think i was having a blonde moment  :redfaced: .
