how can i make a turbo engine out of an b200 engine on a 360

[krazvy]

hello.
i was wandering if i can make a turbo engine out of a b200 or i have to buy a engine with turbo ?
can anyone help me with this ?
the engine is from the year 1983

1983 b200??

are you sure; b200 was introduced in 1985 for the 300 series.

turboing a stock b200 is achievable (there is a 360 turbo currently owned by sliderman wich has it) but you'll have to run it at a low boost because the internals aren't made for high load pressure; imo you're better off to start with a turbo redblock; B230FT for example.

Actually B200 internals are same as the "middle model" turbos apart from the pistons. From -85 to ~89 all redblocks, including turbos had weaker 9mm rods. Safe limit is ~250hp in street use but maximum output I've witnessed is around 400hp, that's not anywhere near on the safe side though because one bad spot in the fuel/ignition maps or too much revs and you'll bend the weaker rods with those power levels..

B230FT can have weaker rods too if it's not one of the newe ones. Stronger 13mm rods came around ~90. I've seen stronger rods on -89 models and weaker rods on -90 models but anything +91 will have the stronger con rods. Those handle same as the older "M"-rods on the B19/B21/B23 engines which is around 400-500hp.

But if the car is really -83 and with original engine it should have B19 which has the strong "M"-rods described above, also if it's the carbed model it has the low 8.5 compression also which is excellent for turbo.

There are many topics about the conversion on the forum.

It will also be a lot harder if you have a high compression version, turbos really want much lower than standard compression (eg 8.5:1).

Earlier cars (UK) used 10:1 compression ratio (CR), later unleaded versions reduced this to 9.2:1.

Really you can't increase the compression above 10:1 so the turbo can't just do anything that isn't gong to melt the engine or blow it up. But Turbos and compression are a bit complicated I can't say I really know.

Definitely recommend 940 B230FT. I know the 1995+ ones are strong.

it will be better to a modification like this : megasquirt unit, the exhaust changed and bigger and a sport carbon air filter ? i want to reach at least 150hp, can i do it with this(for start, beacuse i want to make a good turbo engine, don't want to blow it) ? and for latter a turbo engin 2.3 from volvo ...after 1 or 2 years........ and the engine was taken from a volvo 360 GLE made in 1983(if it helps it's the one with aluminium engine cap(not colored with black, just silver) and bosch ignition sistem

Yeah that will work, you'll get 150hp out easily. Like I said above, max safe limit for the weaker 9mm rods used in B200 engines is 250hp so 150hp no problem!

But is your car year model -83? if that is so it should have the B19 engine. Is the valve cover silver coloured or black? If it's silver the engine is B19 and has the strong internals which are good above +400hp when in good order. If it's black it's the later B200 engine which would be weird for -83 model if it hasn't been changed some time.

Is the engine injection or carbed model because some models have the higher 10:1 compression mentioned above. You CAN turbo with that compression if you use megasquirt but you'll need to be carefull with the pinging. But it's no problem when you take some time to do the fueling and ignition properly.

SJS who also has written on this forum some times took his 340DL with the 16V 2.5l turbo to dyno couple of weeks ago and dynoed 408hp/664Nm (turbo ran out of map, he would've got more with bigger turbo ) and the engine has compression around 10 so high compression will not be a problem if you just pay attention to fueling and ignition.

Out of interest how sure are you of compression ratio's of the B19 carbed engine. I also remember a while back these having low compression but in my 1984 owners manual of the GLS I'm sure it's around 10 something

Well if it's the same B19A as in 240 it has the 8.5:1. Of course they could've changed it for 300-series! If they have used the pistons with the "hump" on the top it is higher compression. With flat pistons compression for B19 would be around 9 and with the ones which have the dish it's the 8.5.

Of course there's also the more rare version of the carbed B19 which is B19K. Those have the 10:1 compression for sure.

the body of the car is from 89 but i had to put a new engine on the car because the original one what drinking gas like crazy...... like 15l/100km....witch is crazy ...so o friend of mine had a engine from his 1983 volvo 360 GLE saloon and i took it and replaced mine with it .... it has the silver motor cap ....
and about the megasquirt .... were can i buy one from ....i am from romania and in my country there are no places available to buy from .... can anyone help me with a online shop and some prices ? tomorow i will make some pictures of the care and the engine to upload here

[krazvy]

can anyone help me find an turbo exhaust manifold for the engine ? i can't find any in my country .....

[krazvy]

here are some photos of the engine

[volvodspec]

just checked some documents;
MY1981-1982 the B19a had 9,2:1 compression ratio
MY1983> the B19a had 10:1 compression ratio
B19e had 10:1 compression ratio
the B200e engine had 10:1 compression ratio

[Fuse]

Ok so it's different than the B19A in 240. Good to know.

B200E is 9.2 up till -87. After that it's 10:1.

[volvodspec]

B200E is 9.2 up till -87. After that it's 10:1.

yeah i know, i checked it for his old b200e, still good input though.

but back to that actually; why is the compression ratio different for the ones from 85>87 and 87> ? is the compression ratio the only difference between those engines; is this the reason there are 2 types of renix for the b200e engine? (411a and 408)

I was going to say removal of leaded fuel over here (reduction in octane at the same time) but the CR goes the wrong way for that...

Did the cam get less lairy and they upped the CR to compensate and try and give the same power figures. Thats what happened with the 480T's, only with boost pressure and cams.
