ksbkrew Posted June 10, 2012 Share Posted June 10, 2012 Hello i'm in mind to rebuild my engine in a near future and i 'm running a single T67 with 850cc injectors. my hp is approx 550hp. i have bought a TT bottom end bored at 87mm from a forum member because i was thinking putting some CP Pistons on the engine. I think i m' gonna go higher in hp and try to go to 650hp. My question is : do i need forged conrods or can i put OEM new one? it's simply a cost question. What max hp does the oem con rods goes to? what safe hp does the oem con rods goes to? thanks to all! Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 10, 2012 Share Posted June 10, 2012 Healthy stock engine will take 650bhp. Set of good BC pro rods was £500 last time i bought a set, if its in bits anyhow id be putting a set in just so its future proofed and all new.

Kaan W Posted June 10, 2012 Share Posted June 10, 2012 I sold my BC pros for about £500. Not a bad rod apparently can take 300hp per rod but not sure if its proven... Some people have had 1000hp on stocks but for how long??? Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted June 10, 2012 Author Share Posted June 10, 2012 so you think it's not a good idea to put some new oem rods on it? i'd better put aftermarket ones? what brands of rods would you put in yours? (in a normal budget!!) thanks Quote Link to comment Share on other sites More sharing options...
Kaan W Posted June 10, 2012 Share Posted June 10, 2012 Personally I would replace the rods whatever the hp if I was doing a rebuild but its all personal prefrence, to upgrade your rods is always a good investment and piece of mind but can the money be better spent somewhere else if your not planning on mega numbers? Normal rods should be ok up to 700hp I would say... Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted June 11, 2012 Author Share Posted June 11, 2012 should be ok safely or near to broke? i don' t want to make mistakes because i don't want to reopen the block after 6months because of the rods i can spend a little more money but just want to be sure of what buying Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted June 11, 2012 Share Posted June 11, 2012 Get your stock rods shot peened, beam polished and balanced EOE and they should be good for 700 bhp. This is what I'm doing so you could always wait and see if my engine throws a leg out of bed Lyndon. Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted June 11, 2012 Author Share Posted June 11, 2012 lol! jamie were you talking about this BC rods? http://www.horsepowerfreaks.com/partdetails/Brian_Crower/Engine/Connecting_Rods/Sportsman/17631 Quote Link to comment Share on other sites More sharing options...
Wez Posted June 11, 2012 Share Posted June 11, 2012 Stock engines have run 1000hp in the US, but a single dyno pull vs daily driven abuse are very different. A healthy stock engine in the UK has been proven many times to be safe at around 650hp as Jamie already mentioned. I believe Jamie also had a very healthy stock engine running approx 700hp and when stripped down one of the legs was a little bent, im sure there is a pic somewhere, maybe Jamie could repost it Quote Link to comment Share on other sites More sharing options...
