Top Mount Turbo Install And Now Have No Boost

Hey guys,

I've recently installed a top mount turbo kit I purchased off eBay a while ago (2nd hand).

Since I've installed the kit I have no boost, it's an oil feed only turbo with a 46mm external wastegate, I've plugged the water lines up and doesn't leak.

I've put the manual boost controller between the turbo and side nipple on the wastegate.

I have the fitting on the top of the wastegate venting to atmosphere and just plugged up the vacuum port that goes to inlet manifold.

I've unplugged the boost solinoid and taken it out (plug just sitting there)

I was set to believe the setup was running 19 psi, I have the stock ecu in at the moment till I can get the apexi. Wastegate spring too high?

The boost gauge is not boosting past 0

Beside all that I have touched anything else :/

Any help would be good.

It's got nothing. I gave it a boot full and still no turbo, I checked the intercooler piping 2wice before starting up :/

Could it be the standard solenoid as I have just unplugged it?

Also because the wastegate is set to 19psi?

When I give it a good revving and back it off the wastegate isn't doing anything.

Well, it would have to be opened a fair way to not allow any boost so I don't think it's your problem. Is it vented to atmosphere? If it is it is (!) heaps obvious if it is open a little or a lot. (Most if it and is in sentence!)

In this order are my guesses.

Dead or dud turbo

Boost leak.

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
