finally got my Z back on the road after 3 months! all running sweet when the car is warm but when its cold there is a bit of a ticking noise which i believe to be the manifold.

 

the really nasty noise starts when i start driving. anything between 2k - 3.5k there is a really nasty screeching sound. dosnt sound like a belt slipping and only does it when its moving, in any gear. its quite a loud sound.

 

also the car feels down on power. im used to driving a fiat coupe turbo with 220bhp so i expected a modded 300zx to feel at least sliiightly faster but it just dosnt.

 

it has full decat, 360 degree turbos, jwt chip @ 14psi, blitz induction kit.

 

i havnt been able to get to a rolling road yet but it definatly dosnt feel like 300bhp..let alone anymore the mods would give it.

 

any help would be great,

hm.

 

sounds very expensive. i think the engine has been rebuilt recently...12k ago ish. and the turbos are relativly new.

 

which manifolds should i go for on replacing mine? also.. is there *any* way of replacing them with the engine in?

If you know for definate the engine is a recent rebuild then your a very lucky guy :D

 

Im afriad i dont know enough about uprated manifold, once again do a search and some research, this site makes research a piece of piss, so much to learn about these cars on here could take you 30 mins to learn everything you need to know about what manifold to use.

 

Well i know its an engine out job to replace turbos so im assuming to get to the manifolds behind the tubs its even further in :(

unless you can get a welder to the manifolds where the crack is....... i dont think so..... haha they are so hidden even from underneath :(
