Red, Random, UFB, Cheuk, or whoever,
Will the lower compression pistons with the HP Turbo kit fit in the 1.8L engine?

4DoorGL didn't think so, but on hmaservice, they have the bore for both engines listed as the same, only the stroke was different. So it looks like it'll fit, right?? Or will the shorter stroke really screw up the compression ratio? Haven't worked the numbers yet, so I'm not sure.

Also, other than less power, will there be any real differences I should worry about slapping this thing on a 1.8? I think the crank, rods, and head should be of similar quality (strength-wise).

Thanks in advance,

The pistons from the 2.0L and 1.8L share the same part number (I'm talking HMA stock equipment) so they *should* work. Since the cylinder head is the exact same between the two engines, the static compression would still be the same as UFB is quoting.

HOWEVER...

Because we have no conclusive testing done on the 1.8L engine, there's no telling about the crank. Gut instinct says it will not be a problem, but there's no guarantees.

That's what I figured.

Red, if I buy that 2.0L from you, we have a 1.8L Elantra here we're turboing. I can open up both engines and see what differences we have between them.

Thanks guys. I won't be ready to buy until late spring anyway, and will use the interim to get some tools together that I'll need. I already have a good set of wrenches, ratchets, pliers, and a big-ass rubber mallet.

Any idea what specialty tools I'll need, specifically for the head removal and piston removal? Also what about testing equipment? It sounds like there's a pretty comprehensive list with the instructions, any way to get that posted? I'll ask over on HP as well.

Thanks again,
AC

How badly would the tuning be affected? Would it run rough -- i.e. so I can get it to a tuning shop to fine tune the chip?

Or would it not work at all?

For reference purposes, I get a compression ratio of 7.9:1 for the 1.8L Beta running your low compression pistons.

This assumes that the head volume and bore are the same for both engines and that the stroke and stock CR are accurate.

Another option is getting a 2.0L crank and conrods, but that's probably expensive.

would the turbo work for 1.6 betas?

well then let me ask wht is the difference in the 1.8 beta to the 2.0 beta the bigger bore and wht gives the 10 extra hspwr from the 130 elantra engine to the 140 tiburon engine?
