Since my engine damage i have been doing a lot of research into ARP bolts, As my standard main bearing bolts stretch under the forces my engine was making i thought it would be a good idea to upgrade and here is what i found.
If you google ARP 1.8t 20v main stud & nut kit you will most likely end up with a link to a US site like IE that shows you a good price on the part but you will have to pay tax and duties, shipping and a 3 week wait.
IE don't give out the part numbers as they claim they have them made for them? Ok can you get them in the UK? Yes Bill is one of many. Anyway i was nearly sold some main stud ( not by Bill ) that i was told were for the 1.8t 20v. I was told they were for all water cooled VW's but i found out ( Google again ) that they are the wrong ones when in fact you need ARP 201-5001 these are for a BMW S14 4 cylinder and are a perfect fit with only a little grinding to the sump as seen on Staceys thread page 29.
Another one is ARP flywheel bolts for the 1.8t, Google that and it will come up with a US site selling them $120 inc shipping ( £80 ) + taxies to pay on top. Again some research on Google and i found the sizes of the bolts needed for for the 1.8t and also a part number of 254-2901 on a US site but with that part number you get to many bolts and with finding out the size i found that you can buy just to one bolt if needed http://www.part-box.com/product_info.php?products_id=37447 or ARP Ford 4.6L 5.4L Modular V8 Flexplate Bolt and for a gran total of £28 for 6 bolts delivered.. not a bad saving don't you think?
So my advise is to everyone is to do your research on the parts before you buy as you want to get the right part and at the best price also
