Forged rods for 1.6L engines

[precisionboost]

http://www.importperformanceparts.net/

Go in under the Vauxhall or Opel applications, click on connecting rods and then K1Rods

The forged rods are $389 per set which is the first "reasonably priced" set for the 1.6L

I assume if you go in for the Wiesco forged pistons+ K1 Rods there will be a discount

I also noticed that if you go under "machining" they will charge $2229 for a complete "performance" rebuild with forged components installed.

That's a pretty decent deal considering the forged pistons/rods are nearly $1000 with the rings

This is a "short block" rebuild which means you need to strip down the engine and remove the heads/manifolds/electronics and everything else so that all that is left is the block/pistons/rods/crankshaft/oil pan/oil pump

If they are doing everything else for roughly $1200 that is a pretty good deal.

I have a feeling you would be able to get other parts included at a discounted price

goody, august here i come

So the pistons/rods for an x16xe are the same bore/stroke as the aveo, or does it take some modification to the block/head to work?

[Petrified.Rabbit]

i am sure precision did his homework, if he says they then they fit.

[precisionboost]

If I remember correctly the X16XEV had slightly higher compression at 10.5:1 but other than that I belive everything is a go.

The Wiseco pistons come in...

8.8:1 for turbo
10.5:1 for standard
11:1 for more power
12.5 for extreme all motor

Looks like the main difference between the Z16LET pistons and the X16 is the piston pin diameter ( 19mm vs 18mm ) but I have think they are identical other than that.

[Matt]

Awesome, I was hoping they were that close.

Is it possible to get a 8.8 compression ratio piston at 81.0mm? I bored the block and using 81mm wiseco now. Just need something even lower compression so that I can run high boost safely instead of low boost currently afraid that the engine might burst on higher boost than 0.7 bar. Any clutch available? Mine need to upgraded to take more abuse. It should be slipping soon due to the amount of torque generated from the boost.

Check with gse_turbo on Daewootech for a clutch kit, send him a pm.

Stock compression is 9.5 so thats pretty good for running a decent amount of boost if you tune the car correctly. I'm pretty sure this engine would take 15-18 psi, you say you already have forged pistons, i wouldnt try it with stock pistons tho. With the right tune i wouldnt see a problem, plus you would make more power at 15 psi with 9.5 compression then 15 psi at 8.8.

The 16 valve daewoo blocks are capable of around 300-320 WHP then you start bursting sleeves. The older 8 valve Opel blocks are much stronger (the old turbo Sunbird 8v blocks if i am not mistaken are part of this). A guy on daewootech has one of these 2.0L 8v Opel blocks with a stock 16v Daewoo 2.0L head, stock crank with forged rods/pistons. Hes putting out an incredible 500 HP and 452 TQ at the wheels on a stock F18 gearbox fitted with an LSD.

From what I remember Gary is running higher compression pistons though (around 11:1 I think)
I think I would be nervous to run any boost on 11:1

[Nemasys]

What you should be nervous about is not breaking any engine components, you can run boost with 11:1 compression but you need a good system and a very fine tuned car.

The problem that comes up is the much higher risk of fuel igniting before its suposed to, also known as detonation. If your fuel ignites before its suposed to, the explosion will force your cylinder back down as its still coming up, results can be disastrous. This is why people run low comp pistons with large amounts of boost, greatly lowers the chance of fuel detonation.

This is what happned to my friend's mx-3 klze turbo, the klze is a high compression engine and he was running 8 psi on it, one day at the track the fuel ignited before the piston passed top dead center and it shatted the rob, broke the piston in 3 and cracked the block the entire length of that cylinder.
