• Hi All.
  i have been a member for sometime now and all i have done is read, read, read, all your very helpfull and infromative threads.
  now i feel it time to ask a few questions, just to make sure i have things correct.
  
  I have had this 1.6 gtd engine (code sb with a garret T2) for about 6 years, its in a mk1 shell, i have driven it hard, standard for about a year, im sure the pump has been very slightly adjusted already as it will keep up with a mk1 1800gti. i also fitted a sports pipe, larger than standard but has mufflers, new straight through in about 3 weeks time
  
  i have this weekend installed a boost gauge and sure enough it was running around 8-10 psi of boost..... i have read the 'more power for you 1.6/9' threads and have adusted the smoke screw a little, spun the acentric cone so as the dimple is opposite the original setting. also turned the star wheel almost one complete turn downwards and adjusted the wastegate so i now have about 18 psi. the max fuel is screwed in just so she idles about right, as backing off the idle screw does nothing to rpm.
  NO govnor mod!
  
  everything seems ok at the moment,
  but have no smoke or very very little under boost, she flys straight upto the 18 psi but feels like it should be giving me more 'go', think i need to encrease the fueling a little more???
  
  right for the questions.
  
  i dont have an egt gauge, im not trying to get her to go balls out, i need this as my daily driver, but where it is right now, power wise is fine, i just wish to fine tune what i have now........ egt gauge on its way as soon as my funds allow!!!(a week or two)
  
  am i likely to run high (read dangerous) egt's with my set up???
  
  Is a little greyish smoke puff on blipping the throttle at idle, good bad, ok???
  
  
  timing is at 0dgr's so is it safe for me to have that advanced to 1.00 will it help lower egts as the burn should be cleaner? or leave it alone for a daily driver???
  
  will running it like this and with 18psi(not hit constantly) available shorten its life considerably? i change oil and filters regularly semi syn 15w40.
  
  
  how would you guys tune it for a fast fun drive, with max psi but with long life in mind.
  
  things i have left to do/fit within the next month
  
  2.25-2.5 straight exhaust from DP back
  FM intercooler from a 1.8d ford focus crashed police car :twisted:
  EGT gauge
  
  
  basicly i dont wanna blow this engine up, but want more than standard power.i like what i have now and would really like to keep it that way.. but i am happy to take any advise any help or  advise on how you guys would tune this would be gratefully appreciated
  
  you have a rockin forum here!!!
  Thanks in advance guys

• Wait for your egt gauge and then you won't have to guess or 'tune' twice.
  I think a little black smoke it healthy  :twisted:

• theman--
  yes i will be buying an egt in the next week or so, this is all for me to sum up over the next few weeks.
  
  just i have read sooo much on here and saved soo many favourites from this site its hard to remeber if all i have read is needed at that stage or if even, things like advancing the timing will be benificial to my engine with my mods :roll:  so was hoping for some good advise-tips on what will make this a fast reliable engine.

• Oh man i hear you.
  My favorites tab is massive and  75% of them are threads from this forum.
  
  Watch your temp. Maybe put in your own coolant temp sender and gauge for more accurate readings. Put it as close to the head as you can. More fuel means more heat.
  But seriously, watch the temp... you may need to switch to two rad fans.
  Use 100% synthetic if you really care about it and want it to last. If 50$ oil is ok with you :roll:
  
  I don't remember if you said you changed the fuel filter or not but that's always a good routine.
  Timing belt too. don't forget the essentials. (which im sure you haven't but there is no harm in being safe)
  Sounds like you really know what you're doing, you should have posted sooner your opinions and work you jerk face!  :wink:
  You don't want to go too nuts with the power without changing to ARP or raceware (is it raceware?) head studs. The more power you make these engines seem to be fine but after a certain point you'll start semi-"blowing" head gaskets or fully lifting the head. 18 psi is pretty beefy IMO for an otherwise stock set up.
  Good luck! sounds good! keep us posted
  
  ps.
  I'm envious of your boost mods; they sound pretty well done. Mine consists of wine corks and what not.

• SMOKEY.
  thanks for the input!
  so you think 18 is pretty high? why? because ive not got the exhaust and other extras yet, or is it fairly high without the MHG and studs, which will happen next year.
  Im not driving the car at the moment, just getting it back on the road after sitting around for about 4 years :roll:  so wanna get it set up before its driven daily!
  so you like my boost pressure :twisted:  (well im no dummy around cars owend a large bodyshop for 15 years, where i created my golf) but all i have done is as i said in my last post, took me around 2 hours, boost gauge is t'd into the thin tube from the inletM to the LDA. thats all ive done and it was hitting 18 psi within seconds of putting my boot down :twisted: but like i say, its not quite got that punch it should have(i think)its fast on the speedo which is reading fine it just lacks that feel you get as a passanger/driver...... the car itself can handle it, coilovers, disks all round with new pipe work and goodridge hoses, 195-45-15F 205-65-15R.
  
  under putting my foot down there is a small puff of black smoke then it clears totaly.... just feels like its running only on the turbo, if that makes sence, nothing major, just 'feels' like it needs more fuel. but like you have said it is running hotter than usual....
  so i think im going to back everything off a bit, untill i get my EGTgauge, then i can safely tweak away.
  
  but please if you or anybody has any tips, does and donts, that you think could help me id really appreciate it.
  
  after cleaning 4 years of crap off, having a bit of paint done to the bumpers and a scratch on the roof i turned to the engine....
  
  New
  cambelt
  fan belt
  water pump
  oil filter
  fuel filter
  oil flush and 4.5ltrs 15w/40 semi syn, going fully next change
  timming set at 0dgrs
  HD flush and coolant change
  brake pads all round
  
  cleaned the brake disks up
  bled brakes
  general 'once over' :wink:
  
  so please anyone that can give me any help here, go right ahead.
  
  
  ill post some pics tomorrow
  
  
  
  P.S ive blocked my BOV with the rubber foot from some old crutches

  or is it fairly high without the MHG and studs

  
  
  I'd say so yeah.
  Other's will say "He's full of $***" but it's all a matter of opinion. There isn't a set number of boost pressure where you can say, well at 18psi yeah you're ok but at 19... oh boy!!! that head will fly through the hood without ARP's!
  HG's are annoying. I did 2 in 1 month... it's annoying.
  Intercooling the 18 pounds will help the "foot down" syndrome. So would sequencial turbos. ... add a k24 before the t3 and you'll know what im talking about.
  Or a properly controlled VNT...
  I'm a genuine assanine moron and i think turbo lag is kinda fun. Wooooooooooooooooooooowwwwiirrrrrrrrrrrrrrr!!!!!!!

  Nice!
  I have 195/65/15's all around hahahahah! on coilies. I can't turn full lock though so i just have the coilies on the back for now (which makes it look like a moonshine runner especially since its flat black... I'm surprised I haven't been pulled over and asked to open the trunk to search for bodies.

  45 series. thats a beautifully low prof tire.

• i have my work cut out with the work i have to do, exhaust, IC, etc etc. but i wanna do it while i have another car so im not driving this around when i could damage it.
  
  I read in another post about the turbo water pump, and mines all wired in, i just bridged the terminals in the turbos sender plug with my ignition off, and it works!!! so im happy the turbo will be cooled correctly

  yeah i hear that! and thats why ive driven it hard for a year, and its been great so far, i know that has no relavance to cranking up a turbo, but atleast i know its not a 'bad' HG

  i have the intercooler, just about to order the hoses, then its being installed! the turbo as it is will give me more than enough for a daily i think

  I don't understand this. I think the performance spec for TD's is 1.05mm. the range is 1.00 through 1.05mm. I don't understand 0??? Some people have gone more than this, but I think they had different break pressures on there injectors. Many guys on here have the performance on TD's down, maybe some of them will chime in. Also where are you located? I am guessing on the other side of the pond from the photos?

  Its just from what my mechanic/friend was saying hed set the timing at when he'd done the TB he said its set to 0 as in standard setting, with all the markers lined up.
  
  yes im from the UK.... and the car looks nice and shiny now  :oops:
