    MaXpeeding Forge Connecting Rods???

    I am in the market for rods and I have seen several options i.e. Eagle, Manley, Carillo, SCAT then I found this maXpeeding rods (eBay) for almost 80% less than the prior mentioned brands. It is definitely made in China but I am not sure with the other name brands where they were made. I understand the one can get what he paid for but if this rod is made with the same spec as the popular ones then it should be comparable right? It uses Forged SAE 4340 Chromoly Steel.

    Is this worth a try?

    I'm a little cautious about stuff like that, particularly internal components. I might try looking to see if anyone on MT.N has tried them, or elsewhere. I guess for the money you might save on them, what is it going to cost you to rebuild if they're subpar?

    What Steven said. I know of people using them with no issues, but does the price difference worth the effort/cost of going all over it again if something fails? Also, what type of build are you aiming for?

    The drastic price increase is a red flag for me. I also saw "MaXpeeding Rods" coilovers on a Youtube episode of The Hooonigans. One of the guys was able to compress the shocks by hand...

    Thank you guys so much.

    What is the best bang for the buck in terms of connecting rod upgrade for our little 1.8?

    My goal is to just make the bottom end a bit more stronger without breaking the bank. I will be adding an FFS in exchange of the JRSC. I blew the gasket on it but the bottom is intact. Since I am in it might as well freshen her up all the way.

    I would not touch the bottom end if not aiming for (relatively) high boost/torque. Check that everything is OK (surfaces flat etc.) throw a new quality head gasket in and maybe some ARP hardware and call it a day.

    Out of curiosity, what levels of boost do you plan on running? I/C or not?

    Just the regular FFS for a 1994.....not sure of the boost level. No IC on needed with the FFS.

    Did not know there was a need to upgrade the internals to run the standard FFS kit.

    If it is the need or the technically challenges that is the reason for the lack of IC with the FFS kit is a discussion on its own.

    There is no need to upgrade but since the short block has over 180k and it is so easy to just remove it and freshen it up with new rods as some claim the weakest of the internal parts....I figured to might as well up grade it.

    Altho’ the FFS may not be as powerful as the other turbo kits.....I have proven it to be very reliable in my 1999 10th AE.

    I share a similar sentiment as Harry. Build the engine for the power goals and purpose. I think a lot of people do things in engine rebuilds that aren’t really beneficial, but they like adding them because they offer protection or added performance.

    I'm definitely not a cheap-ass on some of these things, but look at your refresh realistically and honestly, assess the needs, prioritize them.
