i just read in the new hci that on a honda b-16 a that a stock rod and forge piston can hold 500 boosted hpi was wondering woould the focus be able to handle the same or any where near that with same set up of couse u would have to upgrade cams port and polish the head and other bolt ons would the focus be able to handle at least 300 whp of stock rods and forge pistons any
any insight would help thank u

the rods are the first thing to go in the standard zetec engine. good for about 250 wheel hp I believe. tom would know for sure

With a really good tune and high oct gas Tom was able to get over 300 on a stock motor

why rods i would think the piston first well maybe i m wrong

Zetec rods are powdered metal, SVT rods are forged.
10-26-2005, 10:23 PM
nobody is answering my question is it possible with just forge pistons to reach 300 whp safely zetec rods are cast
10-26-2005, 11:01 PM
zetec rods are not cast actually no engines really have cast rods any more powdered metal is cheaper and lighter, id spend teh $400 on eagle rods for insurance
10-26-2005, 11:07 PM
yea get some new rods to be safe

You dont need forged pistons to reach 300whp, you dont have to have forged rods either. Tom made 300whp on a regular Zetec.... as a matter of fact there is a post on here about it.... maybe in the focus power forums.

Tom has done it just to say he has done it. As I have made 300 myself with 116 gas and stock rods. But it's not something you want to rely on everyday IMO.

Here is the thread I was talking about earlier
PSI on stock rods thread (http://www.focusfanatics.com/forum/showthread.php?s=&threadid=62498)
Hope this answers your question[thumb]

Ok so if you change out to rods for stronger rods your car will be stronger at the basica PSI preasure like on my engine it's 8psi.

I went for Crower Rods and Diamond pistons (8.5:1 compression) which will easily cope with 300WHP. stock internals at 300WHP, you'll need to run high octane, or at least use a thicker head gasket (or decompression plate) to lower the compression. running well over 300BHP at the engine with standard compression isn't recommended at all. im suprised people do it to be honest, but then some people push it until it blows then rebuild the engine with uprated internals, but dont think stock internals will last for ever.

Tom has run his SVT at 17psi since he first put the turbo kit on it in 2002.
