Before we even pulled the engine yesterday due to the oil / water mix in the radiator, the smoke from the exhaust and the general fit of engine we knew there was troubl e ahead, but add to the mix that this was once rebuilt by Ztech ( now a defunct outfit ) and was one of their famed "Forged variety" the reveal was well no surprise,

 

Standard pistons, rings rods, bearings, and nice standard head gaskets, trouble is the car had been set up on the understanding it was strong biggger injectors, bigger turbo`s and boosted etc. but the build was poor, the amount of excess silicon sealant was a joke, the mixed up bolts and missing brackets etc. was plain lazy, but to charge for one thing and delivery a hold lot less is unforgivable, this is one of many engines from the same bunch that were rebuilt with standard parts but charged out as Forged.

Why do this? if your getting work and been paid accordingly then why cheat? they were never in it for the long game, just a quick buck and off in to the sunset.....

 

So under pressure the standard parts had let go with broken piston rings and worse heavily marked bores, one bore has a sort of roll in the metal!

 

Be warned about any engines from this bunch.

I was another who was ripped of by this lot as was my friend karlos g ,

we were both ripped of at same time , I sadly sold my zed after 6k spent inc new engine fitted by a proper zed mechanic not a chef .

 

there might be my old thread somewhere ,i spent 3.900 pounds to have uprated turbos bottom end rebuilt inc bearings etc ,and few other bits which were never done ,

car never even made it home 80 miles away it locked up almost wiping me out on the m25 i was facing the wrong way going backwards with a hgv hurtling towards me ,

end cap wasnt torqued properly came loose as thread was stripped conrod threw side of block , , even after the car went back to him it wasnt untill i got it trailered that i noticed a lot of my mods and gearbox parts ecu etc were missing , no doubt stolen to fix other cars , , this expereince killed any future happiness for me in zeds ,

 

Thankfully when it came to sell my now running zed my"upgraded" turbos were smoking , oh and they were stock ones by the way resprayed ,

 

Then A very good zed place called z world , hope there still running , had very kindly offered to recon my turbos for free when i sold the car to a the new owner ,"now had new engine fitted and new gearbox "and all missing parts replaced ,

 

Mainly because they had heard of my plight , And offered to help me out ,

I am so glad that there are people out there willing to to help put a few wrongs by others right ,

 

hope my old zed is still going sold it to a really top bloke in portsmouth , reg h**3dmy in black auto tt

 

anyways i heard a ztech was taken over by his brother ?

Hi paul its been a long time fella, i still have some pics of your old z somewhere.

These last two pictures show what appears to be severe detonation damage around the lip of the bore, the final picture highlights this best, which would have resulted in the cracked ringlands and the subsequent vertical damage down the bore from the blow-by. Saw exactly the same damage on an RB26DETT block at the rear of cylinder 6, running 500+bhp with a faulty fuel pump causing it to run lean on boost. It's the most common failure on Skyline engines. Too much boost, too much heat, too much knock.

Hey guys yes i got a few pics too still somewhere ,

 

my son is hooked he wants a twin turbo 300zx ,

 

seen a nice 5k one on ebay not sure about the guys feedback though is he on here ?

 

how all you lot doing i bumped into Jason farrow at a meet in november froze my nuts off , ,

Hello Paul, long time eh? and yes we are still going and the good news is so is your zed! it returns here each year for service and MOT etc.

 

As far as Ztech is concerned they are well gone despite a few reincarnations their poor rep could not be shaken off.
