Alright, so I'm just about to purchase my s4 TII swap from Japan2la, and I came across the post from Chris Boots about some of the little things that you'll need to do.

He said I also needed these;

TID, BOOST SENSOR, BLOW OFF VALVE/ BAR, and the FUEL PUMP are the things that I still need to pick up to finish the swap.

My question is, would I be able to just temporarily block off the turbo and not install the intercooler yet, and run the car untill I can come up with the cash to buy those parts?

Or, Would I be able to throw in the old N/A intake and exhaust temporarily untill I can come up with that cash?

Any alternate ideas would be imensly helpfull, I just need a car to go to and from work and school.

 

Far too much work, and not even heard of to turn a turbo into an n/a because well its retarded... Get the parts if you buy all that used shouldn't cost anymore then $50-100. You don't need an aftermarket bov, get a stock one until you can afford an aftermarket.

 

Yup........Do not start the swap until you have everything, see if japan2la can source you those parts and sensors. Dont forget airflow meter and throttle cable too. Clutch slave cyl if you are installing t2 trans, and stronger NA clutch if you are using na trans.

Correct me if I'm wrong... But, the way you say that you make it sound like the BOV is included in the Japan2la engine swap deal? Or, does it come on the Turbo Inlet Duct?

And, I'm only looking into not installing the turbo and intercooler temporarily... I really need a car at the moment in order to get funds to finish this part of the project. My only concern is that by blocking of the turbo or running N/A intakes and exhaust manifolds may harm the engine...

In short my question is, would converting my TII exhaust into an N/A by removing the turbo and blocking it off damage the engine in any way?
Or, would I be able to bolt on my N/A intake and exhaust without harming the engine?

Please and Thank you SO much,
Scott

 

actually, you can keep the turbo attached. Just bypass the turbo inlet by plumbing your intake (after the MAF) into the intercooler. It shouldn't hurt anything. You will probably want to run the NA ECU, MAF, Boost sensor, and injectors.

THis shouldn't hurt anything, and you will probably get some cool turbo noises!

P.S. put a filter or some obstruction in front of the turbo so it doesn't injest anything.

 

your NA exhaust I think will bolt on if you want to go that way, but your NA intake manifolds will not bolt on without some modifications.


If you follow the suggestions of my earlier post, you will still need the TII throttle cable.

What transmission are you running?

 

Hey,
I have these parts and can add them to your package deal for a decent price..
S4 TII TID
S4 TII BOOST pressure SENSOR
BLOW OFF VALVE ( Use the OEm one that recirculates)
FUEL PUMP ( Buy a walbro, I have them new on the shelf... less than $100.00)

 

That will cause the turbo to overspeed and fry its bearing and chum its blades. Bad idea.

Good idea.

 

why would it cause it to overspeed?

I know of a few people that ran there car this way in order to break in the engine without using boost.

I am not trying to be argumentative, just wondering how that would overspeed the turbo?


Is it because the wastegate would not open?

Thanks in advance for the info.

 

it can be done 100%

slap on a non turbo exhaust manofld and your done with the exhaust part.

then ust run the standard turbo intake manifold, and somehow run the airflow meter on teh other side.

no big deal really. youll just need to change out the flywheel for the same series engine flywheel that is non turbo. got that? good.

thats pretty much all you have to do.

its been done many times before.

 

the turbo isn't building any boost, so the wastegate (which runs off boost pressure) will never open. and it'll just keep trying to build boost (spin faster) until it explodes...

 

+1

but it seems kind of dumb... basically your swapping in a working NA (I assume) for a much slower non-turbo turbo engine... why wouldn't you just wait till you have all the parts?

btw: you would also have to cap/block off all the oil and coolant lines for the turbo if you replace it with an NA manifold.

 

well, sir, you dont need a non turbo intake manifold. like i have stated before, just run the turbo manifold. the actual water lines are easy to block off and dont cost much if anything.

remember to plug the oil feed line.

its been done before, and the 4 port doesnt produce any less hp. people have dynoed 180+ rwhp on a turbo keg converted to na with no porting and just a tune.


JUST DO IT ALREADY!! its so simple to do, it hurts.

 

well sir , when I referred to the "manifold" I meant the exhaust manifold...

and it'll make less horsepower due to lower compression and an inferior intake manifold design...

 

So, for the Engine/Tranny combo with wireing harness and ECU ect. Plus the above parts what would the total come to?

Oh, and are your engines rebuilt and, do you recomend a break in period?

 

I'm not swapping from a working N/A, I had started to rebuild it, (rear rotor had 70 psi on all sides,) and then found out that the rotor housings were both shot and the rear rotor is no good, little sister dropped it and made me very angry that day... That being stated I decided that the price to fix my six port N/A was compareable to doing a TII swap. So, that's what I'm doing.
