Mating with Renault 172

Post by RickS » Wed Oct 01, 2014 2:52 pm

Hi guys 'n gals.... New kid on the block, so please be kind...!

The title says is all really. I've had a run through the topics here but I apologise if this has already been discussed. Is it possible to mate a Renault 172/182 type block to a B18 block..?

Thanks in advance for any input and opinions if this has been done before

I think Slash knows best about this sort of stuff. Are you thinking about grafting the modern Renault head onto the block? I havent got a clue by the way but I am interested!

I was more thinking of putting a complete N/A engine (Sump to rocker cover(s)) onto an existing 5 speed manual transmission.

To be perfectly honest, I'm not sure exactly what I DO want. I was clearing out my spares shelf in the garage last weekend (I'm finishing building a Lancia 037 Group 'B' car) and came across a brand new Garrett T3 the ended up not being used, so there might be some mileage in Turbo-ing the B18. I just don't like bolting performance bits onto a motor that was not designed to take the stresses. In my minds-eye I see a fully sequential, normally aspirated 16v 2lt jobbie, giving me 225-250 HP.

I would like to de-clutter the car and end up with a 'Street Sleeper'/Track Day car. The body and underside are now fine (since I've had the sill 'shuts' welded up) and the rear arches are repairable.

Just digging and turning rocks over to see what's possible.....

Thanks for the nod Tim. I've checked Slash's posts regarding the Rally 480 and he sure has done some research..!

Now that I'm starting to get a little comfy with the Volvo/Renault naming standards, it is becoming a little clearer (pride goeth before a fall!). F7R looks like what I'm after if I choose the N/A route and I'm comforable with that. As the 5 speed manual gearbox 'appears' to be standard across the board (?), I'm just looking for confirmation that the faces will align/mate properly.

Back to the Interweb I guess..!

This looks really interesting Rick, I'm keeping an eye on this as I always prefer to upgrade parts rather than replace them like for like, I wuld just bee looikg at going for a more efficent 16v engine I think, so I might just keep an eye on ebay for bargains for the next 5 years, which modles did your engine exisit in?

Don't quote me on this but I think the Renault JB series of gearbox's are what the Volvo M series box's are based on. I believe to put a Volvo box onto a Renault engine or Renault box on the Volvo engine you need to move a locating dowel from one position to another.

The clio II 2.0's are I believe the F4 designation engine's. These are completely different from the F2 or F3 engine's.

Converting a Volvo B18 or B20 to 16V is impossible. Easier to put a F7R from a Clio Williams or Megane into the 480. This has been done before I think and whether the Renault gearbox was used I don't know. The Driveshafts fit the same way in the Volvo's as the Renault's. i.e Nearside is slotted in and the gaiter bolted to the box, the offside is connected to the intermediate shaft with two roll pins. So it may be possible to put a whole engine/gearbox into the 480 keeping the 480 driveshafts. as long as you get the alignment of the engine right in the bay.
There are always ample warnings and there are always subtle signs,
And you would have seen them coming but we gave you too much time.

Cracking stuff and just the info I was looking for. Regarding the models Tim, just the 480'S' I believe but I could be mistaken.

I will soon have the room in the workshop to get an F7R up on the engine stand and check out the 'mating ritual'. If it's just relocating a dowel I should be able to accomplish that (or get somebody in who can!)

Many thanks for the update and advice Slash..

What about a Volvo T4 engine...I think this is similar to the Laguna N7Q (plus a turbo)

A worthy entrant to the list of possibilities..... and something else has just reared it's head that may warrant discussion.....

I have been going through a list of vehicles that will/will not be compatible with E10 when it becomes the norm and the F5R does not come out too favourably. Volvo, funnily enough, do.... So whether the tank and plumbing in the 480 are OK, but fuel rails, injector seals, regulator on the motor aren't, I think is worthy of some further investigation.

IS E10 ethnol / petrol mix fuel? Isnt fracking etc going to push back the demand for that sort of biofuel? (not trying to be polical here just asking the q)

Yessir... E10 is 10% Ethanol 90% Unleaded, rather than the E5 which is 5%/95% (I'm sure that you get the idea) that's currently being sold.....
Maybe this should go to a different thread......

Anyhoo, thanks all for the Renault/Volvo mating info. It's given me food for thought. I'll update here when I get the project started...
Best regards, Rick
