just a quick question about forged engine. Anyone know how you'd confirm if the engine is "actually" forged internals without having to strip it down somewhat.
I mean we've got receipts for an engine in the Rb25 to be forged & it defo does sound that way but would a forged engine have - higher/lower compression figuers higher redline etc oh... on that note can someone shine some light on why random fuses would blow in the fusebox?? i've checked for short circuits from the board & water ingress all seems ok.
thanks
Forged Engine! TELL TALE SIGNS!!
Re: Forged Engine! TELL TALE SIGNS!!
mac here ,both tough questions , especially whether an engines "internals" are in fact forged parts ,and I'm assuming typically is crankshaft , rods ,pistons . The oil pan ,if easy at all to "drop" is one way -but that's as youasked ,kind of stripping down . Do the rcts. name the component's supposedly "Forged" ? 
Random fuses is more my expertise , and a very high "over-volt" situation , if 'n you're alternator goes high , maybe way high , but that usually fries basic components in addition to "random fuse blowing". Contrary to belief that ECM will fry on over-volt is (for late model cars) a misconception ,because your "Modern" control boxes ,ie. ECM , trans ctrl,ABS ctrl etc. have whats called Transient Voltage Surge protections within / throughout so if the voltage does go way up - and especially huge spikes that are so fast ,they'll tend to blow a fuse ,yet NOT do what one would think of obvious damage to those TVS protected "Systems".
In fact you hear of the dreaded EMP from nukes ?
That are supposed to fry electronics , well electrical engineers have for decades better & better protected circuitry in most all equipment -obviously our missiles must be able to deploy!when fairly close to an EMP 
Back on topic- more likely very very bad "Custom wiring" is a huge factor , if was done extensively and maybe these "new" circuits are not fused right , or faulty/erroneusly designed ?? 
Somebody with an Oscilloscope ,especially a "Digital - Sampling Memory " type - it captures the problem on the screen and "holds" an image / reading ; whereas high volt gets "shorted to ground" through these TVS protected components and the O-scope can show that spike voltage captured or if the tech wants to "See" the actual over-current that's causing the blown fuses by connecting across a series connected "current drop resistor".Serious auto tech's know this stuff !Hopefully near you, good luck

hi mac massive thankyou mate 
you certainly got it locked. yea ive studied vehicle electrics a bit & will fly over what you've said been real manic round here with the weather an all that but right back to biz now. i've decided to drop the engine one day to get to the bottom of this & follow your suggestion on the electrics.
