Hi, I have looked up some turbos and I wonder if a T18 turbo will fit and work with the rest of the car.
Do you guys have other good turbos for a Volvo 240 to show me?

-Thanks

 

What year is the car?

Just slapping on a turbo is not as easy as you think. Turbo engines have a few different parts than non turbo engines. The parts are piston heads, injectors, the addition of oil and/or water cooling lines, an intercooler (if you want one), and head gasket to start off with a few parts.

What some of the 700s had before the 90's were Garrett T3 turbos. After 1990 they were equipped with Mitsubishi TD04s (which I have rebuilt). The difference between them is that the Garrett had better top end performance, but had a fair amount of lag. The Mitsubishi turbo has almost no lag, but does not have as well of top end performance.

Also, how mechanically inclined are you with engines? Putting on turbos with not a lot of experience will be difficult for beginners.

 

I see, I am fairly new to cars and turbos. The model I have is 1978 dl. I have friends that have innstalled turbos and I want to learn it my self

 

Ok, maybe the easiest thing for you to do is find a junkyard Volvo 200/700 series (maybe a 900 as well) with a turbo already equipped and take the whole engine, wiring harness, intercooler, computer, ect.
You could also ask your buddies for some help with installing a turbo on your car.
What make cars did they put turbos on?

 

I'd suggest finding a 1994/1995 940 turbo thats been tail ended, and swapping the engine, harness, ECUs, fuel pumps, intercooler, larger radiator, everything. probably should take the AW71 transmission too as its much heavier duty than the 1978 vintage trannies.

 

Will it work if I get a 940 turbo, then buy turbo piping/manifold/set/intercooler for 240?

theoretically, what will happen if you mounted a t4 turbo to the volvo 240?

 

your 240 is ancient, its an old B21 or something engine. with probably CIS injection

the 940's use an updated B230F engine, 2.3L, the turbo engines have lowered compression, special valves that handle higher temperatures, and the 94/95 turbo's have piston skirt lubrication squirters inside the block that keep the engine happier under high loads. These use LH 2.4 fuel injection rather than CIS (K-jetronics).

T4 is a nearly meaningless out of context brand name for '4 cylinder turbo'. mostly was used with the whiteblock 1.9L motors used on the V40/S40 series of FWD cars. those have NOTHING in common with the 'redblock' motor series used on RWD 240/740/940

 

oh., and 240's were never intercooled, they introduced that with the 740 turbo

 

Thanks for answers, I will figur out something

 

a t4 will never spool. you want a t3/t4 hybrid or t3.
something with a .53 or .63 exhaust housing.

 

I suggest this as well.
If you want to turbo charge the motor that you have currently, then you'll have to tear the engine down completely and spend a lot of money on it than what the car is worth. It's cheaper just doing an engine swap.

this page, looking at post #37 is something that is always open in one of my browser's tabs. Lots of information here, if you really want to turbocharge your 240. One of these days, I figure on doing something like what has been done. But, I haven't even had time to finish my fuse box projects, so this project is some time [think years] out for me. Keep in mind that this guy is really going for a good amount of power. Putting a Turbo on these engines with higher compression is cool, but has its drawbacks, too, but the poster goes into that.

As I see it, if you are new to cars and turbos, and have friends that are doing this, Help them do it a couple of times, then tackle your car.

Best of luck whatever you decide to do.
