Issue fitting my single turbo

hey, well i managed today to get down and remove the stock twins, and the manifold.

problem is that when i put the manifold in all is good till, i add the snail on.
it wont fit due to the side near the passenger wheel is theres these metal lumps that are just not letting my turbo fit right, is there anyway to cut them down? to fit the turbo in . i have a knock off gt45. really good for the price ( please dont rage at me ) im not as funded to be buying those 3k turbo kits like everyone else

well heres the picture of what im asking

thanks in advance guys!

Hammer it in, Also might want to move that ABS line or else the **** is going to melt ( I had to move mine.) My turbo sits on that as well, Its literally touching, Just havent had time to take it off and hammer it in.

I personally would just hammer it, wont take to much, if you did cut it you will have to deal with covering it up and getting a heat resistant material. Hammering it out should work.

Thanks you to! Also do you have a turbo blanket for the exhaust housing for the turbo? If you do I would reccomend putting it on BEFORE you install the turbo.

Don't do it. Knock-off turbos are never a good idea. GT45? as in, bigger than a GT42? Sorry bud, but I see many many problems in your future.

I would suggest you stick with the twins for now, and save up until you have enough funding to PROPERLY go single!

Buying knock-off parts that don't even fit, without really knowing whats going on, is just asking for more (very expensive) trouble in the near future...

Hey, at least you didn't remove the engine and install everything outside of the car. That would have been a heart-breaker to get it all assembled, then surprise!

Hmm GT45...that's a big turbo. Eyeballing the compressor map for that, even at 15psi boost looks like it'd be surging. I may be wrong without properly mapping it, but...I'd probably go with a GT35R, T04R, etc...

Assuming your A/R...

Also, if it comes down to having to sacrifice your Power FC, then you won't be able to generate much more power than you would with the twins at stock levels anyways, due to increased fuel demands. You might not be able to afford a 3k kit NOW (and realistically it'll end up being more than that, from how my own project is coming), but it may be wise to hold off and save up a little until you can afford it. Otherwise, you may be looking at spending that much anyways on a rebuilt engine.

What other mods have you done to the car so far, in terms of exhaust, fuel system, etc.

it has a catback exhaust, fuel system well i have the 1680cc sitting but i been reading they wont fit in the stock secondary fuel rail ? theres not much about that topic on the forum. (or i haven't be able to come up with the right phrase), its a stock port, right now im in the process of remove all emission control. thats about it.
and the power fc thats on it way.

Honestly to go from bone stock (which it sounds like you're basically at) to a reliable single setup you can easily expect to spend upwards of $10k.

I know that sounds like a lot, but there are a lot of ancillary parts you're going to need in order to support a single. I would REALLY encourage you to keep your twins, map out your path of needed mods, and slowly build up to a single. Do the mods slowly so its easier to afford, and so that if something goes wrong you can identify the culprit more easily.

Remember, there is more to a single setup than just a turbo... Fuel, drivetrain, boost control, cooling (air and water/oil), EMS (the pfc is getting out-dated, and there are MUCH better ECUs for a single), ignition, etc well need to be upgraded, nitty to mention that you'll also want to improve your breaking and overall handling to. And that's not even getting into added water injection..

with mods on stock FDs you should really crawl first, then walk, then run. Don't try to sprint with your first step unless you really know what you're doing, and you can afford it.

He probably got that ebay GT45 which costs like $200 on ebay. Its not as big as a real GT45R. 68mm if i remember right. I hear those turbos blow up easy and can cause engine damage when they sent parts down the intake.

T04Z, good street turbo. Should fit but depends on the manifold.

I've been running the Apexi PFC myself for about 5-6 years now. Don't get me wrong, the PFC is GREAT for entry level applications (twins running under 400whp) and can definitely support what the majority of FD owners are looking for.

However, once you jump into the realm of singles and higher horsepower there are much better options. Myself, personally, I'll be switching to a Motec (M84 or M800) this fall.

People will say that you can totally tune a PFC at well over 500whp, but the difference between the ECU's boils down to how smooth and in-depth everything is. There are many subtle inputs that the PFC just doesn't recognize, where the Motec can.

If you're on a budget the PFC is probably better suited, if you're willing to put in the cash for "quality over quantity" than I'd get a Motec (M84, M400 or M800 series) or Haltech (Platinum Sport series).

Don't run anything other then a PowerFC in an FD unless your tuner specifically tells you he wants another ECU. There is nothing budget about a PowerFC other then the fact that it works without spending a ton of money installing it and getting it to work. Trying to reinvent the wheel is where the headaches begin.

Need help with a PowerFC? Everyone on this board can help you. Not so much for other ecu's. Anyone that suggests to a newcomer to the forum not to install a PowerFC on his FD that isn't involved in the tuning of their car, is simply giving bad advice.
