hi guys a little help pleeeaaase!!!
i have a very nice mk4 golf gt tdi. but the engine is total wank!! and im having endless problems with turbo related issues
i want to know is it possible to put a 1.8 gti turbo (petrol) engine in my mk4 gt tdi (diesel) car??? without much hassle how much of a problem would this be? then my plan is to put a audi tt turbo on the 1.8 gti engine. good idea or do you see many problems?
im not to bad with fixing cars but im a lil new to enhancing performance ect!
#any help and advice would be most welcome :)

Cheaper to fix your current engine as you'd need all new fuel lines, wiring loom, ECU etc etc
What engine do you currently have and what's wrong with it?

hi
its the 115bhp 1.9 gt tdi ahf engine.. the engine its self is ok'ish im just fed up of the constant turbo problems! and even with the turbo working fully its just lacking the power i desire.
but im inlove with the car! so im wondering if the 1.8 gti turbo engine with audi tt turbo be worth it and how possible is it? i know the gti turbo engine puts out about 150bhp but im wantin a 200 to 300bhp car so with the tt turbo and ecu re programmed im guessin i can achive this??

To convert back to petrol will be a ballache, might be better to find a donor car.
-
Why swap out an engine for an engine that is already existing in the same model?
If you want one then just sell the tdi and get the 1.8T it won't cost as much to do either.
If you want more power, remap it.

im sorry i dont think i put across how much i want to keep this car!! as its got a beautiful interior plus spray job suspention and r32 body kit nicely finished! im wondering if its easier to put a petrol engine in which wil allow for a better performance range?

It will but you looking at changing a lot of parts

Diesels have one of THE most usable power ranges in a modern car.....
Have you looked at remapping it? Get in contact with either CCT or R-Tech.

In answer to your question, you will need the fuel tank, pump and fuel lines, engine, engine loom, ecu, clocks and gearbox. A lot of time and a large pocket because you will undoubtedly need new gaskets, washers, seals, oil, coolant, spark plugs, filters etc etc etc
Good luck :grin:

im guessin you are a fan of the vw tdi engine, agreeable slick? but if you were me at this moment in time and have had the issues i have had with this engine/turbo/vacume/constant lack of turbo.. there for driving around in a 40mph car is quite annoying! i do like a turbo diesel when going rite! but at heart i love my petrol engines :)
any1 know if the engine and gear box mounts are different from the petrol and diesel??

thanks for being direct :) its going to be more of a long term project so im okay with the spending money and i.m thinking (i hope im rite) it will be wel worth it if its possible

115bhp versions are bab, dont blame you,
easier option would be finding a PD150 TDI lump and mapping it, had one and that was pretty rapid, that way you wouldnt need to arse about changine fuel pump, lines etc

yes very good point :) cheers! i wil keep it in mind and if the gti turbo route fails i shal be goin with that option

I'm a fan of most diesel engines. That's beside the point though.
What I'm getting at is, like the others have said, you will need to replace pretty much everything underneath the bonnet, including fuel lines, tank, pump, filters etc.
If I was in your shoes and the problem is as big as you say it is, then I'd be more inclined to try and pick up a 1.8T (full car) and then swap the bodykit and all the other gubbins over as it will be the easier way to do things.
You'll need to swap clocks, looms, and all that stuff as well.

I think this is a more realistic route, diesel/petrol swaps are always a pain because it's a very different setup, get a tried and tested pd lump and then spend your money on that.

What he said.
There are some really decent diesel engines, even a TDI 130 can be remapped to 170.
If you went for a more powerful diesel engine, you'd probably still have to swap the gearbox and possibly the fuel pump (to keep up with demand) but still much less work than a TDI > Petrol swap.

I'm not being funny with you, but if this is the case why did you buy a 115hp diesel?
It's like saying you bought a kiddies paddling pool but you are really dissapointed becuase actually you wanted an olympic sized pool.
As almost everyone has said before, buy a faster car to start with. It's not just a case of sticking MOAR power in, you'll have to upgrade almost everything anyway.
