tuffers Posted October 12, 2005 Report Share Posted October 12, 2005 Any thoughts and ideas on how the sdi could be turbo'd? Ive been looking at the high flow intakes from allards but not gonna buy anything until ive researched it all properly.Whats the difference on the intake part of the engine between a SDI and a TDI? Ive looked at my sdi and it has a throttle plate and i presume a sensor just before the intake. What does the tdi have? Ive found a flange match with AHU and ALH tdi engines so im thinking i could go with a sump, intake and downpipe off these.allardsIve already got a new VNT15 turbo with exhaust manifold in one, and the flange matches perfectly. As far as controlling the vanes, ive discussed this with lots of people and i think theres a solution other than installing a new ecu and loom. It should be a good choice for low rpm spooling.

Ramirez Posted October 13, 2005 Report Share Posted October 13, 2005 Havent got a clue about anything diesel, but i'd said it'd be easier to just get a TDI or have I just missed the point? Quote Link to comment Share on other sites More sharing options...
M1 Lupo Posted October 13, 2005 Report Share Posted October 13, 2005 I had looked into this when I had my SDi. I then found out that it was going to be costly. It was cheaper to swap it for a TDi. But as you already have the turbo and manifold, why not go for it! The SDi has what looks like a throttle unit, its not. Its for air flow smoothing. The engine's speed is varied by fuelling pressure as far as I could see it. As for controlling a VNT turbo, you would need a good aftermarket ecu or possibly adapt a VAG one.

tuffers Posted October 14, 2005 Author Report Share Posted October 14, 2005 I then found out that it was going to be costly. It was cheaper to swap it for a TDi.I understand, but would a 1.9 tdi fit into a lupo? cause i dont want a 3cylinder tdi.Heres a link to the gtd forum where some guy tried to control the vnt15. Although he was kinda unsuccesful the thread has a few ideas. I like the boost elbow idea, that would be the cheapest.http://www.vwdiesel.net/phpBB/viewtopic.php?t=1306Ive also been looking at the greddy profec boost controller and i think it could control the amount of vacuum to the actuator.Ive been told if i fit a high flow intake i may not need the anti shudder valve (the bit i mistakenly called a throttle plate).

Blue Loop Posted October 14, 2005 Report Share Posted October 14, 2005 1.9 tdi fits but do you really want that much weight on the front?? i'd go for a 1.4 TDi if i were you tbh style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...

Also im pretty there on a list of parts required. Gonna give the greddy profec boost controller a go.Got the VNT15 turbo.High flow intake. 9possibly allards)Tdi sump or fit connector to existing sump for oil return line. (possibly allards)turbo oil hoses.FMIC and hoses. (anyone recommend a fmic size?) Tdi downpipe and custom exhaust. (would be nice to have a centre exit)induction kit.Any ideas welcome.

Blue Loop Posted October 17, 2005 Report Share Posted October 17, 2005 Theres a guy in germany who has (or at least had) a Turbo'd SDi, might want to send him an e-mail.

Tigz™ Posted October 18, 2005 Report Share Posted October 18, 2005 Seems like a lot of work for 95hp doesn't it?Or am I missing the point?The engine will still be excessivly heavy. Quote Link to comment Share on other sites More sharing options...

DJ Posted October 18, 2005 Report Share Posted October 18, 2005 Chip a TDi and if you do it right with a coupl eo fother engine mods you can get 115bhp and over 200lbs/ft of torque for less work than you are going to do on the SDi lump.Plus you get all the other TDi benefits on top.

tuffers Posted October 18, 2005 Author Report Share Posted October 18, 2005 Seems like a lot of work for 95hp doesn't it?Or am I missing the point?The engine will still be excessivly heavy.The turbo is the lump added. The fmic and pipework maybe wiegh just over the replaced airbox and piping. So i reckon about 10kg at the most added. Could this not be compensated elsewhere?

Wouldn't you agree the a 1.7 4cylinder would have more potential than a 1.4 3cylinder? Quote Link to comment Share on other sites More sharing options...

DJ Posted October 18, 2005 Report Share Posted October 18, 2005 1.4 Block is aluminium as well IIRCPeople have looked into fitting the 1.9 TDi Turbo and intercooler to the 1.4 TDi and this looked quite promising but very expensive.Why bother with the diesel when for the money you could go and get yourself a nice GTi or subtly mod a TDi.

I know the weight is different to a lupo but i imagine its the same driving on the motorway screaming at 5000 rpm, doing 75mph. And it certainly doesn't pull away quicker than my sdi.

nfbr Posted October 18, 2005 Report Share Posted October 18, 2005 For starters the 1.4 TDI is a PD engine...If you do manage to get the turbo onto your SDI, it probably wont be any quicker than the 1.4 tdi, as your not gona be able to match the performance of Presurised fueling.

nfbr Posted October 18, 2005 Report Share Posted October 18, 2005 PD technology isnt just more fuel though... some VW tech guy was explaining it all to me, but its a hell of a lot more technical than just throwing a crap load of fuel in each cylinder.and even if he feeds more fuel to the 1.7 (which he'll have to do to run a turbo anyway) its too easy to end up with nothing more than a lump of black smoke!! been their myself when tuning the 306, took us nearly 6 months to get the fueling right so it wasnt "too" bad for smoke... and in the end i sold it anyway cos the fuel costs were skinting me lol.£10 = 30 miles Quote Link to comment Share on other sites More sharing options...

Steffro Posted October 18, 2005 Report Share Posted October 18, 2005 The 3L lupo is a 1.2 Tdi isnt it? Quote Link to comment Share on other sites More sharing options...
tuffers Posted October 18, 2005 Author Report Share Posted October 18, 2005 (edited) yeah 1.2tdi is the euro 3l i believe.There are all lupo weights. And kerb side weights, whatever that means. Anyway it shows the sdi and 3cylinder 1.4 tdi weigh the same. Edited October 18, 2005 by tuffers Quote Link to comment Share on other sites More sharing options...

tuffers Posted October 19, 2005 Author Report Share Posted October 19, 2005 Thats cool tigz. Although overall id say the performance of a sdi is still better than a 1.0. Anyway found this site about vw weights:vw car weights Quote Link to comment Share on other sites More sharing options...
