Motor 810-20 /????/ -Info needed!

[reidalpine]

I've got hold of a 810 shortmotor 1289cc.made by Renault..
810 is the block-code ,but does anyone know the -20 bit?
-The one I've got in now is 810-G-726 (R1225 -1289cc)
from a R-5gtl-77.
I'm curious to know what the sub-codes Really means-Does it have to do with the top-end/cam/leadfree fuel or what??

This new one sitting in a wooden-crate
has ZERO km's on it-and has a note on it saying it's meant for leadfree petrol -More of interest is it says 62bHp
in conjunction with 2-port Weber :twisted:Yummmm..........................

ANY info greatly appreciated! -R.

According to the Haynes Renault 5 manual, the 810 was fitted into the R1224, 1225, 1226, 1228 and R1395. The engine produces 64BHP and the compression is 9.5:1.

It is possible that the engine code may refer to the fact it's lead free by having a lower compression ratio. You say it's a short engine so I take it that the cylinder head is not present.

It would be interesting to compare your pistons in the van with the pistons in the new engine, but that would mean you removing your head. You could then use a burette and measure the volume of the combustion chamber and work out what the compression would be if you used the new engine. All good fun for a Sunday afternoon.

To be quite honest, I would swap the bits over, fit the engine and run it in and then worry about the '20' afterwards

HI there Steve! -My fault-this is a complete motor w.top-end and also water-pump but no starter/alternator/petrol-pump or carb..
what we here in Norwayland refers to as a short-engine meaning without the "salad" or external bitz..
-I've a feeling Some already thinks my head already Has been removed!
Compr. isn't stated anywhere in the paperworks..
I'm thinking this 810-20 could have been meant for the R5 TX Auto and/or the Volvo 340(B-13) plus possibly the DAF66
Am I totally off ??
seems to remember Volvo wanted more BHP in this motor as the Volvo 340 had more Fat to move around ?? -R.

 

[Steve Hennessey]

Ah - well in Uk motortradespeak this is a full engine or in slightly modern terms - a full engine minus ancillaries!! This is good because if it is unleaded then it's a straight transplant. You may be right in that it was made for Daf or Volvo, but were engines of that period unleaded?? I doubt it because you're going back into the 1970's. Unleaded only means hardened exhaust valve seats anyway so try it in your van and see what happens. I converted my R4 to unleaded by having new valve seat inserts and the rest of the engine is standard. If your current engine is OK then is it worth changing it now? Maybe you can carry it around it the back as a spare

 

[reidalpine]

apparently this motor was purchased ,or rather-ordered by a garage for a customer years ago-never collected so have sat inide filled with "storing-oil" and all plastic-plugs intact and in place.Turns smootly..
Not sure how old it actually is-so might have been ordered in the 80's
-What made me intersted was the fact that if Volvo-spec'd it should have longer duration cam plus Maybe larger size valves So hopefully would be easier to "soup up"
Having an extra motor in the back-Would be kind-o' a Midland-ish way of making a 4X4 wouldn't it?? c",) -R.

You may be right in that it was made for Daf or Volvo, but were engines of that period unleaded?? I doubt it because you're going back into the 1970's.

The Renault 9 was developed in the '70's. It's engine was basically a next generation version of the 810 and 688 engines of the R4/5. This new engine was ready for unleaded fuels. Renault was doing some thinking ahead at this point in time by making engines ready for fuels which would come onto the market in the late '80's.

 

[reidalpine]

Blacksmith! Any info what this R9-engine was called? Was it still 810-XXX
-were they same engines as used in the DAF's and later Volvo's ?? -R.

 

[The_Blacksmith]

I shall have a look in the manual. It's commonly refered to as C1 or C2 depending on what carb is on it. Choises were Solex or Weber I think. I seem to remember it was numbered 847, but I'm not sure. My R9 GTL has a C1J-17 which makes it a very early 1398cc engine.

What does it say on the motor id plate of your little treasure?

I've had a quick look in the manual. The R9 engine is a step up from the 810 in horsepower, torque and size. The smaller C1E engine is a direct descendent of the 810. The C1J is a new developed engine based on the 810. This means it was built for the new cars and vans coming out in the late '70's and '80's and meant to be transverse mounted. If the drawing in the manual is correct one could possibly take the C1E out of a R9, tweak it a bit and stick it in a R4. Having never actually seen a C1E I wouldn't take the chance though.

 

[reidalpine]

interesting wikipedia! not sure How correct though..as my 810-G-726 is 1289cc.Info on wikipedia is Off here..
but I got straighten out on one point as I've thought the C-engines was transversal-ones ,now I've got That corrected anyway.
-Won't give up just yet,but must confess all these engine-types and numbers/letters/subcodes are getting to me...
This all started out as a search for an exhaust-header to fit my motor then maybe play around with a double Weber or something..
Driving Roffen on the Continent is no problem-here in N.we have lots of 80km.limits so shifting up from 3rd at about that speed is ok if on flat level ground .uphill it will decellerate so it's down in 3rd again
seems ratio is a tad Too high between 3rd and 4th.
so I feel Roffen needs a Bit more grunt to overcome -Or I might just stay out of Norway which right now (snow reaching the family-jewels)
sounds just the right remedy to me! -R.

Renault 9/11/Super 5 engines are transversely mounted, therefore have a lot of differences than "our" ones.
Daf / Volvo Renault engines were mounted longitudinally, too, but in the conventional manner-timing end forwards. So that also will not fit on a R4.
So if your engine looks like a R4/R5 (water pump on flywheel end), it must had been destined for a R5. What that "20" means is puzzling...could it be a special code for an exchange engine? I am sure that earlier exchange engines had different type numbers stamped.

 

[reidalpine]

will ask for crate to be fully opened then have a proper look at it...Suspect it to be a Renault-made engine for Volvo.will come back with all relevant data as I get them..Exchange-engine hmmm, You might be on to something Angelos.
What would be your pro tip as to Where best to look for some extra power/torque in the set-up I already have (810-G-726.1289cc Solex 32SEIA) Exhaust/Headers/carb(s)/or other???
I'm also once again thinking of 123ignition as I think ign.to be a weak point.Have more info on 123 now -No faults reported,used in a variety of cars (Ren+Citro)for years..so IS this the Holy Graal after all??

-No reply from Autobleu as of yet-They do have a header for the R4 in an "odd" 906cc engine(suspect this to be same block;810)
Did they use this 906cc in the R4 and/or R6 elsewhere than France- I've got no idea..
More important..Is it likely the top-end or rather the part where to attach exhaust, would be the same ??? -R.

Renault 9/11/Super 5 engines are transversely mounted, therefore have a lot of differences than "our" ones.

The only exception to that is the C1E engine which is found in the late model Renault 4 GTL ( Clan? ), Renault 9 C/TC and Renault Super Cinq.

If I guess correctly, they mean the 904cc 3 bearing engine...not officially produced, but achieved with 60mm pistons available from somewhere. It was said to produce 60 HP on Dauphine Gordini R1093 setup (cam, compression, carb). What they mean may be that it works best with that setup. It should fit on a 3-bearing head (but may well not, as there were some Dauphine heads with diagonally mounted manifold studs).


About your first question...I think your engine was the most poweful non-Alpine fitted to the R5 range, wasn't it? I'm no expert on R5 engines, and where they are restricted, so other people may be more helpful (mr-reno-139, for example?)

 

[reidalpine]

Hi guys! I need to start reading stuff more thorougly it seems-the part I Thought it said 906cc -Didn't...
- Autobleu has a header for the Under 900c engines and also have other header to fit Over 900cc. MY mistake-Sorry!

The 810-20 engine I'm on about Was produced by Renault for Volvo 340 auto and is labelled B-130 You might be right that the -20 code means leadfree .
Is said to be 62Bhp. 1mm larger intake valves and +5 degr.longer duration cam. (some say it's the same engine that was used in the R12 Auto and the R15 1,3L) I don't know if these had same specs though ..
Would this be the engine used in the R5 Auto which has 58,5 Bhp??

mr-reno-139 has gone into hibernation it seems c",) or if he's tried his Plein Air in the cold we will have 2 break his frozen fingers off the steeringwheel and thaw him up come spring -R.

 

[angel]

Useful Info, Reidar...But if it's made for the Volvo or R12, wouldn't it be installed timing end forwards? Does your engine look like this? (pulley through timing cover and water pump at timing end).

 

[reidalpine]

All info came from now owner-he opened the crate to get to the ID-plate
I'm hoping to see it myself this week-end to check if it's for Our use....
Why is it I am suddenly getting several offers for complete or partially complete engines when I'm actually looking for headers??? THEIR timing is Completely off front-end Or rear-end.
Got tipped off about a Renault-5 engine this time complete w.2-barrel Weber/starter/alt/w.pump/in/out-manifold (no gearbox) It's possibly for a R5 TS or TX (auto?) 1400cc.58,5Bhp must be the one I mentioned above I guess..this is engine
Type 847-M7-12 could that sound right? Would it go well with my 354-136 gearbox? -Hope you have a good time in Athens Angel spring on it's way yet? Me? -have to get up on the roof tomorrow to get some snow off it or it will collapse I think!! -R.

The "20" could stand for a factory remanufactured engine with 0.20mm oversized pistons.
Incidently, the 1400 engine installed into the Volvo 343 produced 70 horsepower
