oh my bad, umm theres a funny rattle sound come from either the engine bay or around there when i turn the car on, but it goes away? and also im loosing boost?

[RBwhatever]

What mods are done to the car?

Has it been worked on recently?

How long have you owned the car for, or have you just bought it?

When your driving, when is it losing boost? What RPM?

Does it bog down?

Its hard to diagnose problems over the internet. Being specific to all the details is a must

How many kms has the car done? And whats the oil condition and level like?

Does it only rattle when cold? Is it a rattling sound, or a ticking sound?

Ticking most likely = noisy lifters.

Loud external rattle most likely = exhaust heat shield (if fitted).

First step with the boost problem is to check (and check again) all intake & intercooler piping, and check all vacuum hoses in the engine bay.

ive owned the car for over 4 years now, 94 r33 coupe, mods ive done to my car are, front mount,38mm wastegate, cold air box, HKS spark plugs, hks ssqv, thats pretty much it? it losses boost when over 4000rpm? reading my boost it hesitates and drops when full throttle?

the cars done 139k had oil done last month, its more rattle sound, but it looks like its coming from around from where the belts are?

I'd be checking the intercooler hoses first if your losing boost. May be a boost leak.

Has any work been done on the car recently?

Yup.. i'd say KeyMaker's right there...

Sounds like it could possibly be two unrelated problems. Check all piping from turbo to throttle body.

Another possibility could be exhaust manifold gasket. Check it for leaks.
