    99' SC1 to SC Turbo

    Well, its up and running... IMG_20180912_203446.jpg

    8.5:1 Carillo pistons
    Scat rods
    T3/T4
    Electromotive Tec GT

    The biggest part of this build id like to point out is that i used the 3rd gen crank WITHOUT the 3rd gen main bearing bolts...instead i used ARP main studs and the engine just hit 1000 miles on the rebuild without any problems....

    I've been thinking about using the arp main studs with the tie plate, but from my mockup the inserts, like you said will have to be removed or drilled, and at that point what are you gaining by removing them? I can see drilling them but removing them is self defeating. You aren't triangulating the bottom end because of the slop between the studs and the tie plate, you also don't have the inserts touching the nut to "marry" the tie plate to the main cap.

    The ONLY REASON i did this was because i could not source OEM replacement studs for a 3rd gen bottom end....what solidified my choice was learning that those "tie plate"were only introduced to dampen NOISE ....they were in no way shape or form intended to enhance the main bolt's strength....those plates are to reduce noise...this came DIRECTLY from an official saturn training video....i did not have to drill anything...again, i used the ARP bolts because autozone, napa,oreilys, gm parts direct and many other places could not help me...so rolled the dice and sofar so good....ive ran Brett's modified tune upwards 20psi and after the 1000 mile break in period i tore the engine down and nothing indicated bearing damage...

    And to answer your question about the inserts, i just didnt seem the need for pieces that arent secure

    I really thought it through...my first boosted saturn was Mike's "Titan" from TSN and it had a 2nd gen botton end and i daily drove it for years at high boost....
