Self Building Engine

[Batman]

has anyone on here done this?

i really fancy doing this, obviously turbo it while im on so i'll put in forged crank,conrods and pistons.

thinking on getting a second engine i can strip down and build up in the garage i have quite alot of tools but i know theirs alot of special tools i need but unsure what they are, i've done quite alot of work myself before i dropped the 2.0 myself but that was pretty easy having the same mounting points!

building an engine is certainly different, even if i build up so much then have a garage do something that may require to much knowledge and then carry on building it up, i'd get much more glory from it even if it does go wrong!

im picking up my paddle clutch next week anyways

any help would be great

thank you

 

[Fred@BTM]

forged crank? why?

not that hard mate, just some fiddly bits

 

[MarkM]

I would say get a book and have a read first.

I thought about doing this but dont have the spare time. Would be interesting to do though.

i was ready up appaerently forged crank have more give which is great taking more strain due to boost pressure?

i mean if the crank didnt need replacing i wouldnt have to rebuild the bottom end would i? e.g all the bearing and clearences and stuff that the crank lies on?

It depends how far you want to go on the rebuild. I doubt that KTEC strip the bottom end down when they do there turbo conversion.

lol ive just been reading through that! ive saved it all for reference help me make a list of things to do, quite a few specific tools i need!!!
still doesnt look over complicated just alot of attention to detail to make sure everything is correct, definitely hasnt put me off doing it

Its a shame they dont do a haynes manual for this engine.

You could try and get hold of the workshop manuals that Renault use. I am sure someone like edde would have access to them. This would give you part numbers for the tools you need for the jobs I would have thought.

No point at the end of the day the engine is similar to other Renault etc its stuck in so can get one of those manual if need be.

He has the 172 manaul I can send out I belive anyway.

 

[Batman]

dint you email me it a while ago? i dont know if ive saved it or deleted it i'll have to have a look, doesnt the laguna use an f4r? atleast a haynes would give me a step by step well i think if not i'll have to ask edde kindly

 

[Dan@SJM]

its easy top build an engine but its also easier to f**k up if youve not done one before.

they'd have to strip it down cause they use low comp pistons

Do you have to take the rods off to fit the pistons?

How else would you fit new pistons?

As for building an engine, go for it, just dont make the same mistake i did and soon take over your garage with bits laying around (obviously all in an organised but well covered fashion).

Sounds like you need to research the engine before you play about with it too. No point rebuilding an engine with a bad choice of mods. Id also recommend reading performance four stroke tuning, its the automotive bible.

lol was that a stupid question?

How does the piston attach to the rod? You have crank to con rod and con rod to piston connection dont you?

Cant you use a low comp piston on a standard rod?

 

[MarkM]

On this picture you have crank, con rods and pistons.

Cant you leave the con rods attached to the crank and just fit low comp pistons?

Amen to that

No, because you wouldnt beable to get to the gudgeon pin holding the piston onto the rod.

Taking the rods off the crank isnt too bad anyway

I suppose if you had stripped it down that far you would put some new bearings and rod bolts on?

Also what would fail first out of crank, con rod and rod bolts if you pushed the rpm to far?

 

[Fred@BTM]

rod bolts are the weak point

 

[edde]

Rod bolts I'd guess most the time.

 

[Batman]

k-tec run forged conrods so im assuming they've swapped them over the original ones, im gonna replace the bolts for upgrades to as they arent that expensive and still play a key roll

 

[mini-valver]

ARP rod bolts are £80 odd! Head studs etc etc, it'll add up to a fair chunk bud!

I've built a couple of Vauxhall engines, peice of piss to actually build them. However I'd recomend getting the crank and rods fitted wherever you take the bottom end to be decked and honed.

 

[Fred@BTM]

£50 + delivery for rod bolts boyo

 

[mini-valver]

Whats £30 between friends

 

[LegoHead]

If I had the space to rebuild my engine I would have done, but getting K-tec to do it instead.

It's not worth fooking up if you consider that £1500 worth of parts on top of the engine could get knackered if you mess something up.

 

[BenR]

i'd worry far more about stock pistons than i would about stock rod bolts.

 

[Diesel_Power]

A friend of a friend rebuilt some sort of throttle bodied lump for his Ka, all mighty impressive with £5k going into the engine. He didnt time it, turned it over and bang, £5k down the drain.

Four stroke tuning is all very nice if you want to tune a 1960's V8, but even the latest issue is 10 years out of date. When you actually want to do something you find it is very lacking in detail, and full of 'rules' that don't fit. Like most tuners he spends most of the book slating everyone else.

 

[BenR]

Quite correct.

Books are next to useless, they are nothing more than a conglomeration of the trends of the time and the opinions of the author which he has built up over his years.

The real info you simply cannot afford, and it certainly isnt going to come in an off the shelf book.

Move onto the physics and chemistry papers and micro science studys.
