The video's not really good enough to hear what's going on. Just sounds like assorted broom broom and boost noises to me.

But whenever this happens it's usually either a boost leak or an exhaust side leak. Gunna have to pressure test the inlet to prove/disprove that it's there before going on to look on the exhaust side. Unless perchance it's coming from the turbo....but we'll leave that for later, as it's a lot less likely.

i can only hear induction noise, but i'm using a laptop and sound quality's a bit :/

do you have FMIC with t clamps? if its making a loud whistle then it could just be boost leak- undo the clamps and reposition it properly. You can do this anyway for peace of mind

Ohk fair enough, its more of a whine and it comes on and off. Different from high pitch induction noise.

Have a stock FMIC, only mod in engine bay is a bov...

Might have to do a pressure test, Ive been told it could be an exhaust mani leak.

      "Cheap" bolt on turbo on RB25DET NEO

      By MBS206 · Posted

      It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!

      The maxpeedingrods turbo is cheap and bolts on to stock parts. I think you just need a bigger silicone coupler for the intake. Its a cheap china turbo, but it's been running on mine for almost 3 years at 16-19 psi.

      What do they look like right after you've tried to start it with everything connected? Also post photos of what they actually look like.

      Also wanted to say, my new spark plugs are blackened looks like it's very rich. I have splitfire coilpacks but stock coilpack loom and ignitor. I tried directly grounding the ignitor ground to body as well.
