How much boost are you running with factory headbolts/gasket
Hi folks,
just wanting to get some imput on what kind of boost levels you are running with stock headbolts. Is there anyone out there that has installed a set of ARP studs? I know this is a popular mod on the 1.6 vw diesels (which I have had) and they run pretty good boost 15+lbs with thet stock gasket. You can upgrade the head gasket to the metal TDI one for the 1.6, is there a better gasket than stock for the D24T? I'm thinking 15lbs with an intercooler and bigger exhaust... Too much? Thanks, Jason |

1. About the headbolt: I don't know if someby has update the stock headbolts.
2. Max boost with stock engine: I remember read about somebodoy runing 15PSI on with stock headgasket and Audi 5000 intercooler 3.The next step in headgaskets is the Volvo Stainless Steel headgasket 4. About intercoolers: I found the following options: A) Volvo D24TIC intercooler: Was sold only in Europe, is basically the intercooler from a B230FT engine and a special manifold. B)Saab 900 Intercooler: Small intercooler, ideal for be used with the stock (or NA D24) intake manifold. C) Audi 5000: Already done (I gonna post the link later) D) Cheap Ebay intercooler: Already done. (I gonna post the link later). |

Where do you go about getting the stainless version of the head gasket? I'm thinking ebay intercooler, though I have a intercooler from a Audi TDI in the garage that I scored of ebay for $30 that I may use if I can fit it somewhere.
I only know of stock replacement headbolts. If you want to upgrade, arp makes a head stud kit for the 1.6 vw diesels, you would just need 1 and a half sets... Jason |

Interesting, hopefully someone will post up a non ic manifold for sale! Suprising that the dealer can get a stainless head gasket for it.. I didn't think the dealer would have much of anything for the diesel engine.
I have modded a few vw diesels, and rebuilt my 85 jetta turbo diesel... I'm familiar with the pump mods and such for more fuel. Not so sure how the auto trans will handle the power though! Jason |

You don't need that N/A manifold. Just reclock the comp housing away from the motor and use two 90 degree angle silicone couplers, and then piping to the IC. Easy. I even used the 240/740 turbo intercooler flipped upside down and way up front behind the grille. perfect on the 240. however, I am using the EGR Non-IC manifold. I like how this manifold is small and compact plus has the over boost valve.
I am run 12psi and when revving out it will overboost and the valve drops the psi down to 8.. hmm.. I need a stiffer spring. Also not using the stock turbo compressor. I fount a HT182s. I think its .60 A/R... came from the RX-7 turbo II. slapped that on the stock centre and turbine which is .36 A/R. hmm... I have been thinking that I want to get the Turbine housing and wheel from a Mercedes 300TurboDiesel. I believe they have .48 A/R. My belief is that while cruising at 65 ~ 70mph boost will be lower like 1 - 2 psi rather than 4 - 6psi currently. i should note that I have stock downpipe that is coupled to a 3" side exit.
