Hello all. I just picked up my third DSM and this one has some rod bearings gone bad going on! I already pulled the pan before buying it and the bearings are scored up pretty bad. Though, I got it for a really good price considering all, and now it is time to rebuild it!

The car has a recently rebuilt head on it, so I will essentially be sticking to the bottom end. My goal for the car is a 400hp street car that will occasionally be taken to the track. I know many will say to swap a six bolt, but I would rather just rebuild the seven bolt and rock with it. I have not ever done a full rebuild before, so I am still debating on having a shop just do it for me... The last TSI I had put on a new head gasket and all the accompanying parts, but never needed to rebuild it.

My main questions are whether or not I should go for stock rods/pistons or if forged are going to be necessary. I don't plan on every going much further than 400hp as that will already be pushing it on the FWD traction.. And should I also go with a high flow Meiling oil pump as opposed to OEM?
 
I assume you mean a 7 bolt 4g63 2g. You should PM me about my 7 bolt stroker setup I have that will drop in with a rebuild ;)

Im sure many people have reached 400hp with the stock rods but reassurance (forged) is always nice.

When it comes to rebuilding an engine, make sure you know what you are doing. Know your specs, know your tools, dont go cheap, and take your time. READ EVERYTHING. If you have any doubt about anything, search for it or ask.

Good luck!
