bosch conversion
#1
I have just converted my 1.8 dturbo to a bosch pump and now it fires up but it dosent idle, sounds rough, no power when reving and theres alot of white smoke. i am pretty certain it is timmed up correctly. i have changed the studs around on the pump bracket (after already putting it together once lol) using bosch lines and injectors. i recently have just had it gov modded and lda grind.

any help would be apreciated as i have no clue what it could be whether its me done something wrong or if the pump is at fault.

Sorry I havent replied to your last text yet mate. From the sound of it the pump wants advancing, loosen the 3 bolts holding it to the bracket on the cambelt side and the fourth bolt on the right under/behind the injector lines and twist the pump so the top of the pump goes backwards a bit, you can adjust this while the engine is running just make sure you have a firm grip on the pump when the engine is started, then rotate it back a bit and keep going until it sounds sweet, usually just over halfway in the 'slots' on the pump (where the 3 stud come through)

Hope that helps man, lemme know if it fixes it or not

I have just tried to advance the timming (pushing the pump towards the engine) and it hasent realy made alot of difference. do you think it could be the injectors i havent repkaced the seals as i was trying to be a cheapskate and only use them when i do the 1.9 conversionBig Grin

Just wondering have you got fuel and return correct way round i know its obvious but i made the mistake years ago 1st time round, and also found the banjo bolt for fuel in was a return bolt so had the restrictor in hence y i couldnt get it to run for more than 30seconds

Hope i dont confuse the matter,

I would recheck your timing mate, sounds like the pump is a tooth or 2 out.

I do agree with londonlad from previous threads and similar problems because as dan said advancing pump is adjusting timing a fraction so may be a tooth out buddy worth checking over all timing holes again

right i have just re timmed the engine and now it dosent puff out white smoke running sweet. but when i rev it it feels restricted about the time it comes on boost. i have put the lda pipe to the inlet manifold so it should work from there surely or is it just because i havent turned the turbo up yet??

What do you mean restricted? Is it revving cleanly up the rev range? Does it make full boost and hold it?

Fuel filter maybe? Is it smoking at all when you drive it hard through the gears?

Was the Lucas tuned? You may just need to give it more fuel. Saying that you need to be able to at least get it in 3rd with foot flat down to see what's what

Is there any black smoke under acceleration? What is the boost gauge saying on full chat?
