Too good to be true? (cheap rods)

http://www.ebay.com/itm/Escort-GT-Ma...item27c09ffa90

I'm in the market for some stronger rods and the price is very tempting.

Yay or nay?

Look up a thread by Leatherface24 he got some of those ebay rods... I don't know what he did with them but there was a lot of data in the posts.

I read through leatherfaces thread and ended up buying the crankshaft depot rods instead. I believe these are the same ones he purchased, had the correct small end specs, and were only a dollar more delivered.

Hopefully they will work out for me.

As of right now, the stock 99 pistons. I don't plan on changing displacement but may go with some 94-97 slugs. I believe they will drop compression from 9.5:1 to 9:1? If I can find a cheap set I may go that route?

I believe the 94 motors have 8.8:1. The 95-97 have 9.0:1. Then the 99-00 have 9.5:1. I also recalled reading somewhere that the automatics have lower comp ratio than the manuals. I believe all the comps ratios are manual.

Comp ratio in all 1.8s is the same regardless of transmission. The 1.6 has a lower compression motor for the autos.

I was just reading that the autos had a lower compression ratio, might just be the 1.6 but the 1.8 has seen some compression changes..

1.6 Auto: 9.0:1
1.6 5spd: 9.4:1

1.8 99-00: 9.5:1
1.8 2001+: 10:1

Rods showed up today. They are CAT's, look very nice, and according to the spec sheet the 4 are all within a gram of each other.

Unfortunately I won't know if they're any good for a while....

I am making 297whp out of a 1.6L right now with ebay rods spinning to 8k RPM. I bought them from a different vendor, they were cheaper than what you have listed there but they were cat power too so my bet is they are the same. I abuse my car too, it's been taken to two hillclimbs now, about 5 track days and a few nights at the drag strip.

Glad to hear these are a fairly solid rod, I have a set in my build (297/278 FWHP) albeit bought from a European ebay vendor and for considerable more than you guys get them for ($280)
