I think stock 1.6 TD has like 72-75hp and 98-101tq. 80/144 will be a bit more of a challenge... Bigger cold air intake, big exhaust (2.25"-2.5") with no muffler, lotta fuel, and more boost. But... More heat will come from that... I think a 1.6IDI TD in a 2400+ (
) Car will be deathly slow. I just tore a td out of an mk2, and even in that shell it was a slug.
yeah what I dont want is to pitching the wrong odds on my engine, I have a 1.8 petrol which isnt mustang fast but its not bad, so to stick in a Diesel, it could do with a bit of poke.
Its a shame 1.9TD lumps seem to go for so much money.
I mean basically What I see is an engine that I dont really want to waste, I'd rather not sell it off cheap or throw it away if for minimal spend some improvements can be made to make something equal to my 1.8 petrol engine.
The current 1.8 petrol is 90bhp @5500rpm & 107lb.ft @2500rpm with a 12.1 0-62mph time. Unladen weight (5door) 2348lbs/1065kg
The 1.9 diesel came in diesel/TD/TDi with these specs:
1.9 - 64bhp/91lbs.ft 17.6 0-62mph
1.9TD - 75bhp/110lbs.ft 15.1 0-62mph
1.9TDi - 90bhp/149lbs.ft 12.8 0-62mph
so basically my mk3 golf has some figures which I would like to retain. The 1.4TDi in my dads Seat is 79bhp/144lbs.ft and that car weighs about the same as my golf, but the 1.4TDi is a really expensive engine for a 'project'!
Judging by the figures there is no way I can go diesel without losing performance, unless I can crack the power output of the 1.9TDi, in which case I may as well just put a TDi in!
The stock 1.6 NA is like 54bhp and around about 64lbs.ft of torque or something daft, its a really lazy engine!
Anyway enough of the stacking the odds against my idea, now its time to overcome the problems.
So we start with a 1.6NA, put a turbo on it but heat might be a problem. Will Piston oil squirters give me a good helping hand with this? Whats the best way to fit them? is it a total engine strip down or can it be done by means of just removing the sump? to much swarf I guess from the installation. I have also heard of people installing different types, there seems to be ones which have 2 holes to install, 1 for the squirter tube, the 2nd for a clamp, then there are also ones which just seem to screw in?(are they a banjo bolt type thing?)
Oil pump I will be fitting is one from a TD 1600 so oil pressure shouldnt be an issue (as currently it has a Vanagon Diesel oil pump)
Obviously a big intercooler to cool inlet charge air will also lower heat issues with the engine. Now as previously mentioned too big may create lag, but will it be a massive amount? the cooler I have is about 2ft square and 1" thick so can sit infront of the radiator easy enough.
I have a K&N panel filter which I hope will be enough for the Turbo to easily draw through.
I was thinking of mostly using the stock petrol exhaust syste, taking the CAT convertor out and replacing it with a bypass tube, but then there are 2 rear silencers, the end one is a 'sporty' unit slightly more free flowing than a stock one, then there is a stock mid one. Pipe work is 2" end to end pretty much.
I guess the final things really is the fuel pump thing, it was mentioned that the thingy turbo diesels normally have on top (a barnicle?) is for fuel system advance, so surely while I apparently can get away without having one, it would be better to run with one for acceleration reasons?
Its fairly tempting to just bung a VR6 in but this needs to be insurable for the G/F lol and as shes at university, I figured a decent diesel setup would work to her advantage not having to put fuel in so often!
They filter 'ok' but I definately dont think they are a lifetime product like they say they are, I think at the time 5 years ago however there wasnt much in the way of other stock replacement panel filters available at the price. The foam 'Ramair' panels are better, VW even use the foam ones in volkswagen motorsport!
