Dom187 Posted July 6, 2017 Share Posted July 6, 2017 Hi gang, I was wondering people experiences with forged VQ'S. It would be great if anyone with a forged engine could say what went into their build and how many miles they had out of it? Also any detrimental effects they noticed over stock.

350Butcher Posted July 13, 2017 Share Posted July 13, 2017 My engine isn't forged in my Z but I have in the past built a few and run them for few years and over 20k miles in some cases with plenty of track work and hard use. What makes you think a forged engine would be less reliable? For most the whole reason for building the engine is to gain strength and reliability. I would say the biggest killer of engines forged or other wise is poor mapping and especially the case when its turbo'd/supercharged. What plans do you have for yours? 1 Quote Link to comment Share on other sites More sharing options...
nissanman312 Posted July 13, 2017 Share Posted July 13, 2017 I know a guy who's done 3 gtr engines In short he has no mechanical sympathy he will spank it cold and generally thrash the life out of it ..built right and treated right a forged engine should last well I would of thought Quote Link to comment Share on other sites More sharing options...

Exactly this... Providing the build is done right with no corner cutting etc, Mapping is key after! Coming from a few forged builds where either the build itself isn't spot on or the map has been poor Quote Link to comment Share on other sites More sharing options...

TT350 Posted January 13, 2019 Share Posted January 13, 2019 My engine is fully built for boost. I blew up the original standard motor. It's been completely fine. In no way harsher, the characteristics are no different and of course, it's much more reliable.

ZMANALEX Posted January 13, 2019 Share Posted January 13, 2019 Forged motors if built properly and mapped properly and well maintained and driven properly should be extremely reliable and provide loads of fun and longevity. However, the cost of maintenance will vary greatly depending on whether you are planning to be a regular track day warrior or just fast road use. Depending on what power and to what extent you track the car then you will have regular financial outlays. Remember that every time that you "tinker" with the motor then you will probably require a tune. It is very important that your tuner/mapper can provide fast, professional, remote mapping if you are not close to a suitable mapper. Your choice of mapper will depend on your location and what ECU you run with. My 720 bhp/710 lbs/ft track 350Z is running Syvecs S6+ remotely tuned/mapped by Abbey. My 840 bhp/700lbs/ft track R35 GT-R is running Ecutek remotely tuned/mapped by Litchfields. 3 Quote Link to comment Share on other sites More sharing options...
