The last time I took my car to install my BNR turbos, they did it for $800.00 just to take off my stock twins and put the BNR onto it...
Theres a stock set of twins on one of my friend car that I'm going to buy. I don't want to take it to the shop just to take it off... I want to do it myself.. So the question is:

How long will it take to do remove the turbos and put it back onto my car??

What well be some trouble I might run into??

and is it a Big JOB??

 

Get a FSM, study it, and then ask specific questions here. You will need new bolts and gaskets. It's all in the FSM.

 

Just start unbolting things, you will figure it out.

 

do a writeup when you figure it out, thanks.

Why are you switching back to stock twins after installing BNRs?

 

Step 2





Someone with all the right tools, talent and good lighting its probably a full 8-10 hours

Someone who has done it before and knows what hes doing? Maybe 6ish?

Me? 12+ but over a bunch of nights and a lot of double checking

 

Well I blew my motor, so I sold all of my aftermarket parts. I have a new motor now, just need a stock set up so I can run the car.

 

Get a workshop manual
and that is the only tool you need

 

I agree 100%. Took me around 12 hours as well my first time.

My main troubles were studs, oil lines, oil line gaskets, and did I forget to mention studs?

Here is my dirty engine bay when I was replacing turbos and installing RE v-mount.

 

OMG. 12 hours?! Holy... Wow I have so much more respect for you guys who have pulled off and put back on their turbos! I figured it was somethin around the 3 - 4 hr range!

 

You might as well take out the whole engine while you're at it and then do all of reliability mods.

 

Taking out the whole engine sounds a little drastic and very overwhelming for reliability mods.. Especially for novice garage mechanics.

 

Now Now - a new motor is one of, if not THE best, reliability mods =D

Be careful with studs!!!!

 

i think someone named arexseven or something like that already did a writeup with pics. search.

 

Removing/installing the turbos isn't hard, there's just a lot of nuts, bolts and parts to remove so it take a lot of time; especially if it's your first. The place where there will be problems is if the studs on the turbos break off in the exhaust manifold. If they do don't sweat it. Once the turbos are off four nuts will remove the exhaust manifold and you can drill out all the broken studs before putting everything back together. I have repaired 3 studs in my manifold, two of them I had to drill out completely and repair with Helicoils.

 

Best advice.. is to have patience... And PB Blaster.. 2 bottles..

 

My first time doing the swap took me around 5 hours.....but my studs didn't break and two stayed in so all I had to do was slide them right on..

 

Can easily be done in a weekend. You'll have drain the coolant as well.

 

The difficulty of the job depends on a few things:
- if the downpipe was removed recently and the hardware wants to come loose without breaking
- if the turbos were removed recently and the hardware wants to come loose without breaking
- if you have overnight to soak the studs in PB blaster and work on unsticking them (trying to do the whole job in one day is a lot tougher than dividing it into two days, IMO)
- if the car has all of the emissions equipment (EGR, air pump, stock intake) - that stuff is in the way and needs removed
- if you're working alone. The actual pull of the turbos is a little annoying to do with one hand lifting them while the other hand removes the last stud. Also, the heater core coolant lines make removing the turbos quite tight, and if you lack the extra hands to guide it out, I recommend removing these two hoses and hard pipe to give yourself some margin for lifting it out.
- don't forget the time required to refill the coolant and burp it.

It isn't fun when you break a stud flush in the block.
