Rob,There was a thread in February raised by Frank about engine integrity issues, but I think that thread was unfortunately deleted due the usual hostility. I stated that I had core shift problems with my block, and Peter stated they had similar issues trying to find a good block for a big engine build. From memory he said they tried about 6 blocks before finding a decent one .... I believe it.As for rods, I heard of a few cars recently that had lost rods when running around 340rwkws. Peter did state the following on Jun 22 2004, 09:56 AM: in thread http://www.fordxr6turbo.com/forum/index.ph...topic=11347&hl=Mate the T engine is currently in factory stock condition except for bigger valve springs, though we would not recommend any customer to run higher than 330 kW's at the treads unless the engine has upgraded connecting rods. I know that the C and V performance engine is running over 400 RWkW's on stock con rods though this is definitely running the engine in the RED zone and is a risky strategy and one I would strongly advise against.So I'd say run high power with stock internals at your own risk, and don't be surprised if you lose your motor.Brian Link to comment Share on other sites More sharing options...
Guest jteale Guests Posted 01/07/04 06:23 AM Share Posted 01/07/04 06:23 AM I'll let you know by the end of the year if things go to plan. Another machine I would like to see Link to comment Share on other sites More sharing options...

The inspection of my block revealed problems, and some modifications to my block were made. There were a number of people 6 months ago on this forum who told me that upgraded rods were not required, but in this fullness of time it would appear that the advice I was given by my engine builder (ie. Nizpro) was spot on.I have an actuarial and statistical background. My opinion is that there are still insufficient numbers of modified cars out there with 50-100k on the clock. My bet is a reasonable number will have block/internal problems in the future, maybe 2 or 3 years down the track. The point I make is that we may well get 2 or 3 years out of modified engines with stock internals, but there should not be an expectation of say, 5 trouble free years, but rather an expectation that at some time there may be a $5-7k engine rebuild cost, and be prepared for it.You may argue that another $5-7 is a cheap price to pay, and I’d agree, as long as you have the money.Sorry if I sound negative, but we shouldn’t expect that by spending relatively small amounts of money we’ll have comparative supercars with faultless engines for the next 5 years.The current focus is on auto/manual transmission strengthening for quite a few people, when only 9 months ago we were being told that the transmissions should be OK.Only in the future will we have a better idea.Also, we also know that Ford have modified rods and springs in the next model. So mods to the next model may be more reliable than mods to our current version. Hopefully, Ford will improve both product quality and consistency.That’s life.

I have not seen or heard of one XR6T engine with a broken con rod that could be attributed to the higher power level,the facts are it's been piston failure that has caused all of the damage not con rod failure. If the piston self destructs 1st what hope has the con rod got to survive...................think about it. RegardsPeter Link to comment Share on other sites More sharing options...

It has little to do with the power increase but everything to do with the intended engine operating RPM range.This quote is adequate reponse for now.As time goes by our knowledge and advice given to others may well change, as it has in this case.
