In kit form its expensive but realistically a welder is £150 , a turbo is £50 , an oil drain and feed tapped in to the block and sump is free, or go from a pressure switch and some hard piping + intercooler will cost you about £150. Just depends how good you are at welding Smile

Since when did you need to TIG weld stainless steel ? Granted its neater but MIG is fine for a DIY job on a budget with a good shielding technque.

What about a manifold?


Use the stock one for the branches, cut it down / bend it and weld a flange on for the turbo. Its not a 5 minute job , but i rekon it could all be done for around £500 if your handy with a welder or ya mate is.

I would do it this way.

Not completely clued up on all of this, but I'm pretty sure its high priced for a reason. Mission to weld something like that, and I bet DP spent a fair bit of time designing that, correct header lenghts etc Yes

Have a look in the projects section for an example of modifying a standard mani. Not how I would do it but it works if you're on a budget.

it's not just neater, more important it's the penetration.

weld quality rated by the ratio of width to depth of the weld ,
TIG is superior then MIG by this rating and only inferior to the exotic plasma, laser and electron ray welding .

Agreed, and none of which is needed for a 15 year old peugeots manifold diy turbo project. This isnt the space ship enterprise. Mig welding penetrates just fine on stainless tubing this thick. I can only think of one exhaust place that makes exhaust with a TIG welder, 99% are MIG.

that turbo kits is expensive, but its comes with nothing. you need bost pipes a forged engine. then if your doing it properly. head work and cams then an ecu its gets very costly. even more than a charger.

Could be argued that you need all that for the SC route too , or infact dont need it all for a turbo.

Both forced induction , both will be better all rounders with cams , aftermarket management and some flowing. A good reliable 215bhp has to go be achievable on a low blow though ?

Easily. Mine is making 230bhp on 7psi. I'm expecting more (closer to 250-260) once I have the funds to have the timing adjusted on a rolling road and maybe a free-er flowing exhaust.

Yes
I agree you need the same for sc but if it is goin
to be done properly you will spend silly money you
save money on the sc without havin to get a stand alone managemen
.fooling the stock ecu with non accurate figures like u boys with
chargers are doing you wouldn't be able to do with a turbo

Eh? The standard ECU is being remapped for the low boost s/c conversion from Lynx so there is no difference in that respect to having aftermarket management. The only thing you couldn't do with the turbo is control the boost with it (the s/c uses a restrictor ring), but thats not hard to overcome.

if you brought it up ,then you might be surprise to find out that some after market companies ( HKS & others ) uses laser welder in mufflers and other exhaust components, the enterprise is vintage space ship joints by brazing .

if 5 people would want a manifold and down pipe i could get them made in stainless steel by a decent exhaust place for around the 800 mark, equal length so no high temp and no funny exhaust pulse due to un equal lengths.
