hi all

kindly how can i convert my 1993 850 volvo non turbo to turbo .
what do i need to change the engine?the ecu?the transmission?add turbo ?

could anyone help me plz

regards

 

UHHHH, THIS GOT MOVED WHILE I WAS TYPING.

Easiest way? Sell it and buy an 850 Turbo. You basically need to do an entire engine bay swap in order to turbo your 850. N/A motors aren't set up for turbos, so if you did do it, you would either need to do an engine swap or tap your motor for oil cooler lines to and from the turbo. If you did tap lines, you would still need a donor car for all of the other parts, hoses, ecu, etc. And then to top it off, NA motors are only recommended to run about 6 PSI, which is no fun.

Dont even try. Sell and buy a Turbo.

 

I once asked this question myself. It's no fun to hear but really the only way to do it on the cheap is to sell your NA and buy a turbo. Even though the motors look the same on the outside (the NAs and Turbos), it would require an engine rebuild if you wanted to try and run any amount of boost that would make a real difference (different pistons and rods). That's on top purchasing an ECU and tapping oil and coolant lines, reworking the vacuum system and changing injectors. After adding up all the parts and labor it decided I could keep my NA the way it was and buy a turbo (I'll drive the turbo and let my wife drive the NA).

 

dear all

my mechanic told me :

1- we have to remove my engine and he will replace it with B5234T .
2- turbo td04-16t with a new cooling system and radiator
3- remove my old ecu and replace it with an ecu related to the engine.
4- and all new pipes line for water cooling.

could that be done , or i will face problems .

It can be done, but for the price your paying to do that you can just buy an 850 Turbo. And if you're going to have a mechanic do it, it's going to cost even more. I'm not exactly sure, but the engine harness may be different for an N/A and T5 as well. Don't forget new exhaust, you'll need at least a new dp.

I just think it's a little more to it than that and you're going to run into a lot of minor details along the way that will make it more difficult.

 

dear gilber33

why do i need to change my exhaust?

i can tell that a used turbo and engine and ecu are cheaper in my country than to by a new volvo turbo and it's hard to find a t-5 in my country , but i could get the turbo and engine and ecu used by a low price guaranteed to work. for about 800$. with out the cooling system that i have to add. what do u think could it be done .

or u think i will face too much problem.and if what is it .thanks in advance

regards

 

You would at least need a new down pipe, and from what I saw on my car when I put in a new exhaust, is there was no way of just unbolting the downpipe from the exhaust because of the rust on it. Not saying the same is for you, but a different downpipe at least.

And if it's different where you live, I didn't know that because you didn't mention that.

Getting a motor/turbo/ecu for 800 is a fair price. It can be done, I think it's more work than people think. You would need to put in a cooling system, I'm not exactly sure the order of radiator/intercooler and what not on the front is, but the setup in front may be different for NAs since you don't have an intercooler. You'll need all the hoses, you'll need a different PCV system, you'll need a TCV and the harness (since an NA won't have the plug), you'll need the vacuum lines to the turbo to hook up the TCV (or bcv, don't remember which one it is, located by the air box). You'll need to get a boost gauge so you can read boost safely since your car doesn't have a boost gauge at all. You'll need to change the coolant around, since turbo cars are taped off of the reservoir to go to the turbo and back. You'll need a new airbox top, and of course hose to go from there to turbo.

I'm not trying to discourage you, I'm just saying, once you get started, you'll find that there may be a lot more things than you originally thought, and parts will add up quickly.

 

Yes all that your mechanic said is true. You will also need to find a turbo ecu and also change your injectors.... However you will face one serious problem..Be broke. I know you might want to make your N/A into a turbo, but by the time you are done doing all that work and paying your mechanic ... You could have bought a Turbo version and take the money you would have had your mechanic change out your N/A and buy some fun tuning toys like an upgrade ecu, exhaust and a few other things and have a car 3x faster than your converted \N/A.

Haha, extra dots = "post too short"

 

Ive actually been interested in swapping a t5 into my 95 glt 5 speed for a while now. Theres a small volvo shop up in albany, by my school that said theyd do it, but id be more interested in undertaking it this summer as a project (pretty big one at that).

How pheasible would it be to do said swap if i were to get a donor car? I know people swap tranny into auto t5s so it shouldnt be a problem vice versa, i have a pretty sound knowledge of mechanics, but im just curious how complex/difficult it would be to do, and if it would run reliably.

 

Just read this thread. You and him are asking the exact same question.

 

That may have come across wrong, what i was trying to ask was is it possible for a 19 year old in college to do said swap with a donor over the period of a summer, i just couldn't bear parting with my green 850

 

I don't know. That's up to you to decide. Can you afford it? Do you have the mechanical skills to do what they can't? Do you have a place that if it doesn't all work out by the end of summer you can work on it? Yes it's feasible to do in a summer. If you have ALL the parts, you could probably do it in a week. But what happens if your mid swap and you realize that it's going to cost more than originally planned? No one can make that decision up for you, just take into consideration money, time, skills, etc. I'm a 21 year old college student doing basically a complete rebuild, but I will be spanning this out over the next year and a half to insure I have enough time as well as money. School comes first.

 

This is EXACTLY what I did. I took the engine and transmission from a T-5R and put it in my wagon. The engine compartment harness was different so I kept my wagon harness. All connections were there in both harnesses but they were definately different. The most obvious was the grounding point. The wagon had a ground strip next to the battery, the T-5R did not. Also, the wagon had a junction mounted to the back of drivers headlight bucket, the T-5R did not. One thing to note here is that I was moving a Turbo engine to a Turbo car.

 

Yeah, he'll be doing a turbo engine bay to an NA. It's doable, just depends how much time and money you want to put into it.

 

I can see it working but the whole idea just makes me shake my head. Its so computer controlled that it seems like there will be way more headaches than successes.

 

That's exactly what I think. I thinks it's completely feasible, and the basic idea is pretty straightforward, but I just can't imagine all of the little things that would pop up along the way that would just make it a PITA.
