Title: Renault 5 GT Turbo Rebuild


C5 SWH - November 19, 2008 07:46 PM (GMT)
As Most of you know i brought the Renault 5 in the summer and love it to bits. :P :D
Ive decided as a project over the winter months i will rebuild the engine. I didnt want to be car less so decided to keep a eye out on the forums for a engine to come up. Managed to source one last week, Engine, box and turbo all on 68k 150 delivered bargain :dj: B)

Yesterday it arrived so the fun now begins :D :D

I was thinking the same thing..... :rolleyes:

Bargain

C5 SWH - November 19, 2008 08:01 PM (GMT)
yeah 150, :dj:

The car was rear ended so he was breaking it, I missed out on few other goodies he had forsale :(

Chopper - November 19, 2008 08:03 PM (GMT)
Jesus mate thats a great deal - whats the turbo like for play and condition ?

DumpyDave - November 20, 2008 08:53 AM (GMT)
Nice find. It looks really small :haha:

Are you going for a standard rebuild or a high spec build?

What kind of goodies will you be getting for it?

It's a slippery slope though :unsure:

LEE69 - November 20, 2008 11:16 AM (GMT)
Nice, bloody bargain mate!

Pattycake - November 20, 2008 12:41 PM (GMT)
Wow get some pics up of the car itself!! These are a rare classic these days and its good to see one saved and given love and attention. :)

Looks pretty good, there is a little play in the shaft but no more than normal, When i brought the engine i was going to sell the turbo as im getting a new one when the engine is finished but i may keep it as a spare :ph43r:

QUOTE

Mixture of both to be honest, was origanlly going to upgrade the internals, but what ive read they seem to be pretty bullet proof.

On the shopping list along with the usual items will be a new t25 turbo, cam,lightened flywheel, piper valve springs and hopefully the head will have a little work done on it and few other bits.

Talking about headwork, can anyone recomend a place i can take it locally?

will keep you all posted on any progress

DumpyDave - November 21, 2008 09:13 PM (GMT)
Depends what you want done to the head. Bobby's engines in stoke gabriel is quite good. He'll re-lap the valves in for you and give it a clean up and polish. He can be grumpy though so you have to get him on a good day :rolleyes:

Sounds like you done some research which is important before wasting money on things you don't need. Good luck B)

Are you going for a multi-layered shim head gasket? One less thing to worry about if your going to crank the boost up a bit.

C5 SWH - November 23, 2008 07:24 PM (GMT)
Spent a little time on it today, B)

Started by taking to rocker cover off, now i get the first look of what its like in side :ph43r:

Next remover rocker shaft and push rods.

Now time to loosen headbolts, little tap eitehr side and off it comes.

Everything seems ok so far, like most R5 it looks as if its had a new head gasket in the past, all gaskets look in pretty good nick.

Next seperated the waterpump off the head.

Trying to keep things stored tidy and organised, i wonder how long that will last :rolleyes: :P :haha:

looking very good i like it this is the simple bit putting it back together will be the fun part haha

DumpyDave - December 4, 2008 09:13 AM (GMT)
Looking good mate. Is everything thats going back into the block going to be reconditioned/replaced? Glad you're keeping everything in order as it's important (if using the same parts) that everything goes back in how it came out ie the bearings, shells pistons and liners etc match up with the same con rod,piston and part of the crank. If it's all being replaced no problem.

Still keeping the mods quiet though :ph43r:

robinxr4i - December 4, 2008 11:12 AM (GMT)
Great work mate, gotta love how simple the old OVH engines are! Wish I had the time, money and space to build a low compression pinto for the sierra oh well pipe dreams :haha:

Stig of the Dump - December 7, 2008 01:27 AM (GMT)

Nice one mate. Standard bore? Are you sticking with standard rods?

Hope Santa has some treats on board :D

Yeah kept to standard bore size and compression ratio, from what ive read and been told it seems to be the best set up for the 5 and also gives good reliablity.

I think im going to keep the standard rods. Ive been adviced to get them balanced along with the push rods to make sure there all good :D B)

Infectus-Guy - December 19, 2008 07:59 PM (GMT)
Tasty writeup! I'm really liking the "idiot proof" bolt pattern on the crank. Not loving the non crossflow inlet/exhaust ports the same side thing, mind you i bet a lot of R5 owners feel the same. Would love to see a 1.7i turbo lump in there one day! B)

Same sort of issues with the A series engine. In one side out the other is a must for air/fuel and exhaust flow. I cant think of any car that uses this in and out same side method today. It must be said though that it does keep the whole engine inlet and exhaust as a small unit for confined spaces.

Due to christmas and new year ive not spent as much time on this as i wanted to but heres what i managed to fit in.

The engine block has been cleaned and painted red, decided to go for a red and black theme to match the cars bodywork.

I had some paint left over so decided to paint the brake calipers back and front, also repalced the front disks and pads.

Looking tidy mate - you are the attention to detail king :)

C5 SWH - March 3, 2009 03:56 PM (GMT)
Update 3.3.09

Finally got the ball rolling again, after a few weeks of doing nothing but DIY :rolleyes:

I decided to buy a engine stand as they are not to expensive and it will make my life alot easier during the build. When finished it can easily taken apart and doesnt take any room up B)

Now on to the crank and pistons, I got recomended a company Big Jim Racing by the owners club They have over 10 years experience in Renault 5 Tuning.
CLICK HERE FOR WEBSITE

They are very helpful and freindly and with the owners club discount very well priced. This company will also be doing my headwork at a later date.

The crank was cleaned and checked, it was then reground to 0.25mm u/s on the both the mains and ends. The crank was then balanced.

Whilst apart the pistons and rods were then also balanced and fitted together

Also waiting at the Royal mail office in town :angry: is my new bearings and assembly lube, will pick them up tomorrow and then the fun will begin :D :D :dj:

Infectus-Guy - March 4, 2009 12:35 AM (GMT)
Nothing better than a box full of brand new parts to fit! Good call on the engine stand, just picked one up for my V8. That little block looks lost on there!
Guy

DumpyDave - March 4, 2009 09:03 AM (GMT)
Nice to see some progress. Did the crank journels need grinding? I just had mine polished as there was only very light marks on it. Worth getting everything balanced whilst it's out B)

Also nice to see the pressure of lou's thumb has finally let up :haha:

C5 SWH - March 5, 2009 08:00 PM (GMT)
Picked up the bits from Royal mail today, hopefully can get building soon B)

Update 9/03/09

Had a spare half hour today so fitted the liners to the block.

First of all temporay fitted the liners and measured the protrusion of the liners to double check and make sure they were within the tolerances given in the manual. This was simply done be using metal ruler and a feeler guage.

Next fiited the O seals to the liners and also added a smear of sealant.

In they go

The liners were then held in place using the old headbolts, nuts and washers. This will prevent damage to the base seals when the engine is turned upside down on stand.

I just used high temperature engine enamel which was on ebay. Only cost 5 and i give the block 2 coats, painted all my brake calipers and still got half a tin left. B)
