My Engine Build

[Mitchy]

The only 3 LCR's i know of at or around this 350bhp figure are.....

Songmans 370bhp (uprated internals)
Aidy's 350-360bhp, he's now sold it to another chap on here (standard internals)
Mine with nos 360bhp and a whopping 400lbft+ (standard internals)

Not to say there aren't anymore running around with this 350 figure, these are just the cars that i know of. Mine and aidy's still running fine on standards (Mine 2+yrs)

I do believe 1 guy, cant remember his name went through 2 engines. However this was not down to excessive power as it was only running stage 1 map. Down to poor mapping and detonation more likely or changing from 6th to 2nd and sending a rod through the floor.

In the press release for the LCR, it did say the engine was strengthend over its former 1.8t engine. Now im not sure what this meant entirely but if the previous 1.8T engine was capable of 350bhp and the LCR engine was strengthened over this then it doesn't take the brains of einstein.

The top tuners all say 350bhp limit, but im not so sure if they have the evidence to back this up seeing as all the failures are from the earlier engines.

I could be talking a lot of bollocks, i often do But my own evidence supports the fact its not going to let go at 350/350+ levels. Ive been abusing mine over 2 yrs now at very high torque levels and yet still going as strong as the day i 1st bought it!

It will be interesting to see how Aidy's IHI gets on with standards.

Oh and what aspect of the uprated rod is actually uprated? Is it tensile strength? As far as im aware, they're replaced with same 20mm pinned rods, just ''stronger'' whatever that means.

A lot of gthe yanks on vortex say internals are safe up to the 350whp range, and thats not mentioning which wrist pin size engine. Personally i think the upper safe range on standard internals are 350, it might actually be more, but at least your giving yourself some space for error.

And my scat rods look completely diferent to standards, cross section is different, not sure on the material/finish/manufacture but they look a lot stronger on the entire length of the rod.

I think you'll probably find the LCR/S3 comes with forged Mahle pistons as well which seem to be good for silly power.

Down to poor mapping and detonation

it wasn't that

material.
forged not cast

 

[ibizacupra]

well thats not the rods fault... lol
forget the name tho off hand... did'nt he get banned off here?

as an aside... I got told a funny the other week.. A fellow combe racer in a civic type r blew his motor a few week back, miss shift of gears got 1st from 2nd when aiming for 3rd - 14k rpm and big big bang. Spoon engine dead. ker-ching.

he's been b0ll0cked by his team for buzzing it previously too from the gear change miss's. they'be now programmed his motec dash to say W A N K E R when he over revs it, which made me LOL

i think most tuners want to err on the side of caution when advising, not good advertising for them telling you its good for 400bhp then they start letting go!

 

[Mitchy]

In the press release im almost sure the new engines came with uprated forged components. I'll try and dig it out.

 

[Ruddmeister]

LOL, no just pointing out the 'real' reason some failed

Yes he did get baned

 

[Yumann]

material.
forged not cast

std rod are partially forged.

 

[DPJ]

std rod are partially forged.

You mean forged after they were cast, rather than machined from a forged billet?

 

[Yumann]

A billet is just a cast product, which can then be secondary processed by forging depending on the complexity.

What you say doesnt make sense as there both the same thing.

 

[DPJ]

I'm sorry, I assumed that compex forged items were manufactured by being machined from a billet of metal that had been forged first.

 

[ibizacupra]

some modern rods are made from sintered material... called snap rods... wonder why?!?!

Fords btw...

 

[Niall]

Sintering is used a lot in modern automotive production, like components for door locking window mechanisms etc. Cause of this is due to more and more complex shapes and price

 

[Feel]

Lets not forget that some standard (i.e. not remapped) LCRs chucked rods too, ISTR. From the pictures I saw, the rod bent and punched a hole in the block rather than breaking off at the gudgeon.

Also, let's not forget there's quite a few more APY, AMK and BAM engines out there that aren't in LCR's.

Billet is a confusingly overused engineering term, IMHO. Like Widget or Spigot . It's often used to describe the "thing" that you start a process with. When it's used in American English and Custom cars/bikes it actually contradicts what I was always taught it meant - a billet (like Yumann said) is actually a lump of cast metal, as produced in the foundry. I think it comes from some old english word to do with sleeping soldiers - if you've seen the billets lined up, it makes sense.

Anyway, I'm rambling - 'billet' is often used to describe the "thing" that use start a process with, the correct term is actually a blank.

I have no idea why I decided to type all that

definately price... ford ones are scarily feable...
makes you appreciate the vag 1.8t motor and what it puts ups with on std components

 

[Yumann]

Update:

I am really pissed off with this guy that has done my head cause one of the the valves seem to be leaking. What a f***ing total monkey.

I'll be naming and shaming very soon, and the tuner he does work for really annoyed.

How the hell can people call themself a business operating like that!

This will be the thrid time the head has been stripped total bolloxs!

 

[The MoffMeister]

o dear sorry to hear that it does annoy me when you pay good money to get something done and you expect it done right first time just a ruddy pain when you have to keep going back

 

[Yumann]

**** it i just partially rebuilt it myself, at least i know its build properly now

As for when stripping it back down:

All the cam shaft caps were the wrong way round

Swarf in one of the caps/bolt holes

Cleaning solvent in most cap holes


I'll be kicking up a fuss tomrrow, and I expect some money back!

 

[Feel]

Well, when you said one of the valves was leaking, I thought you weere going to say he'd taken too much out/caught one of the valve seats...

'tis a bit shocking though.
