my mate wants to know if he can run a turbo setup on his motor which has a chemi welded head? anyone done it, will it hold up with the extra strain?

if he is thinkin of a turbo, and can afford a turbo setup, why not fix the head first? If your going to do it, do it properly.

thanks that doesnt answer the question i asked at all.
i have mates that have turbod there patrols for well under 2 grand and a new head is a tad over 2 gs as i have priced them in the past. i also think there is alot of tb42s driving around with chemi welded heads un known to there owners. i have already replaced my head with a freshly reco head and if it happens to crack again there is no way il be replacing it again, apprentice wages, buying a house, and trying to build a turbo diesel aswell there is no way id fork out 2 grand for another one.
all i asked is if it has been done or not

chemi weld IS NOT a permanent repair. it will fail regardless of it being turbo'd. The extra pressure will make it fail faster.

Chemi weld is also hugely abrasive, if it leak into a cylinder it will work it's way onto the rings and ring lands and will damage the engine.


that is all the answering you need

Totally agree with Brad-chevlux,
Mrs had a Mitsubishi Scorpion with the 2.6 ,The head cracked an we tried chemiweld ,A couple of days later the motor seized .
When we pulled the motor down you could see where the chemiweld had gone through the entire oil system, due to a crack in the head that ran from one of the water jackets through to an oil gallery.

Best to get the head fixed properly first instead of trying to band aid repair

Its just not worth the extra pain an expense

thanks guys
thats the type of answers i was after.

depends HUGELY where the head is cracked or corroded.
if it see's comression, highly unlikely it will last.
If it does not see compression, it will probably outlast the rest of the head.

I've chemiwelded a turbo rb30 that had blown the gasket and not cracked the head, the car did just over 2000 kays and blew the chemi out again, so we re did it and went about the same kays again before we pulled the head, its great if you want to buy time but won't last forever.
