volvo 340 1.7

Post by **schakal** » 22 Mar 2006 12:08 pm

i am after some technical info for this engine , anybody know what sort of power they produce ?? and how easy are they to tune ,turbo etc .

basicly i am after some hassle free extra torque for my renault 9 1.7 gtx ,which has exactly the same engine,the ignition coil etc as the volvo 340 1.7

any help would be much appreciated
cheers

It's possible, the turbo Volvo 480 uses the same block, Huskyracer on here has put one in a ex1.4, and is pushing over 200bhp, not sure if it would a case of new manifolds, changing the head and sticking injection wiring and fuel lines in, or if the block itself has to be changed though.

I've just started running the same block, and as I'm thinking of doing the turbo to my 1.4, am looking at sticking a set of bike carbs onto my 1.7, but don't yet know enough to understand if it'd do what I want.

200 bhp is a bit too much for my liking though ,i would be well happy with just over 110-115 ,hence i am after the less hassley mods for my car .
been told the 480 turbo camshaft (270 degrees compared to the standard 220 degrees one on r9) would give some torque and power , but as far as i know you need a ported head etc to gain real power from a wild camshaft ??????

on the other hand going into fuel injection is a lot of work tbh , the fuel pump on the r9 is a mechanical one ran in the head by the camshaft . which means i will have to find a suitable fuel tank with a built in pump to go on there ,also linking the wiring from the engine to the dash would be difficult i suppose ????

Not sure about cam stuff, I'm not far enough into this yet. One of european guys stuck a 400 carb on, and reckoned he saw some power.

The 480 turbo block is 125-135 as standard, just Husky is playing a lot

We run the same fuel pump by the sounds, I know husky did nick some bits from an Uno turbo, so that might explain the fuel pump, but he's just bolted that on after the pump iirc.

As for dash lights, nah, easy job (well for a 300

), I've been playing with 400 dash's to nick one of there trip computers, and they run very similar senders to 300's all the way through. Speedo on a 340 is mechanical, not sure what it is on yours, so thats untouched for us. I'd imagine your senders are the same as ours, so your dash lights must be pretty similar.

Hey, horses for courses, but I'll be intrigued to see what you come up with, sounds like we are after a similar thing, as I'm only after a tad more power from this one (well.. just not the 175ish I'm looking for from my current 1.4).

As Chris said turbo 480 engine only pushes out afaik around 120bhp but it'll be a lot of work for you to convert the fuel system for a turbo application. Best bet is either going to be a 400series carb or some twin carbs and a decent cam. Im not too sure that a turbo cam will help as from what i've read in the past they are fairly different, NA engines get their power by revving high whereas the turbo gets the power in other ways (from the turbo lol). It really depends what your capable of doing, twin carbs would set you back a fair bit for some twin 40s and give a decent power hike but then you'll need dyno time to set them up at £60/hr! As you wouln't need to modify the manifolds on the 480 engine like us its probably a very easy job, sort out a new fuel pump and fuel lines and a custom downpipe, then run it all off the normal 480 ecu, should just be plug and play with no dyno time required. Probably the cheaper option as long as you can sort the fuel lines and pump as the lump can be picked up for cheap. Also the potential for a lot more power in the future

what sort of power he saw , do you know ?

you mean you got the same mechanical pump on the head ???
i think that can be just blanked out and a electric pump can be located in the bulkhead ???

my speedo is mechanical too ,only injected renault engines had the magnetic speed sensors that would also affect the running of the engine.

Looking for the same for my 340 1.7

Some options that I'm thincking...

- Put the B18E from a 440 and run it with carburator. This motor have more compression ratio than the B172K (10.5 vs 9.5)

- Put the 2.0 from a Laguna, wich I thing is the same that can be found on 400's 2.0 (we don't have that engine in the 400's here in Portugal) and run it in carburator

You can always forget the carb and run them in electronic fuel injection

Without changing the engine... put the camshaft of a B18E, less restrictive exhaust manifold (again B18E is the best), Volvo 440 GL carb, or modified gigleurs on your carb.

would not the bore differences on 1.7 and 2 litre engines cause trouble ???

i also have 1.8 cylinder head from a renault 19 1.8 8v which looks pretty much the same as the 1.7 head from the outside apart from the threaded holes on it for the electrical sensors etc.

i am sure someone on here must have done some mods on these engines and would come out to share with us sooner or later

Just the head in this engines will not do anything. You can drop in all the 1.8 engine...

there is another thing that bothers me though ,whats the standard power output you get from your 1.7 volvo ???

the renault 9 1.7 carb engine on the r9 produces 92bhp but i believe thats because of having no power steering and no inj. hence no catalytic convertor (these two steal power from the engine on renault 19 s. ie : a renault 19 1.8 single point injection only pushes 95 bhp where as it could probably produce over 100-105 without the cat and the power steering )

also you say you are running your 1.7 engine with some volvo 440 carb , what sort of power do you get from that ???

My 340 don't have A/C or power steering...

He must have arround 90hp

it says 80 bhp for the volvo 1.7 340 on carstats.co.uk
on the same site it gives 2 different renault 9 s with same engien but different power output 82bhp and 92bhp
very strange

1,7l 340 is indeed 80hp.

Some cars have same engine but different carb/cam setup that makes sportier version of model. Don't know if this is situation with Renault?

Post by **schakal** » 23 Mar 2006 03:34 pm

not sure what they did there ?
but on my logbook it says the car is 92 bhp (which i never noticed in real life due to bad carburettor )

Well bu tI have the 440 gl carb, wich had bigger jets...

440GL have 92bhp
