building a 2.0 or a 2.3 stroker?

[seyzar18]

So i just got back into the dsm word after being out of it for 7 years and im getting ready to send the block in to get some work done to it. Some things im trying to decide on is

Do i bored it 20 over and get new fordged pistons and new rods etc...
OR
Do i build it into a stroker 2.3?
I dont know much about stroking it so if i go that route what compression ratio would i go with and what would be the best set of pistons rods and crank to go with?

i want this motor to be around 450-500 whp in a awd so i know its going to take alot of work but i dont know if id rather do a stroker or just bore this block and make it 20 over what one would be more reliable? Ill still drive it on the street every now and again but not everday.

if i bore it 20 over and new rods pistons etc what kind of crank should i look at getting? The head has already been ported and polished with a 3 angle valve job and i might replace the valves but not sure if im going to do that yet im going to look at see whats in it for valves right now. If i stick to doing this what ratio should i go with again? i thought about bumping it up to 8 or 8:5 would that be better over stock or should i stick with stock ratios and just do a fordged piston. I know its alot of questions but like i said iv been out of this for 7 years so its going to take alot to get back into it and remember what im doing. and ideas or pointers on internals would be awesome, the block is going in this saturday so i need to decide what i want to do before then so whats the Advantages/disavantages over 2.0 to 2.3 stroker?

This is all a matter of opinion. IMO leave it a 2.0 and rev the piss out of it. A stock crank is good for well over 600hp, and as far as the pistons and rods go its a matter of opinion also. I would suggest eagle rods, and Wisco HD pistons .20 over (8.5:1). Throw some acl bearings in that bad boy and a Precision 6266 and feel nice and cozy to about 700hp. I assume this is a 6-bolt of course, don't forget to eliminate the balance shafts!!! A stroker is a faster spooling, lower revving engine typically, while a 2.0 is opposite, it's just a matter of opinion.

yeah thats correct its a 6 bolt and the balance shafts are already gone on this block.

depends on what you like. if you like street driving and autoX then i'd stroke it. if you like drag then the 2.0 build can rev higher. but IMO I built a 2.3 with eagle 100mm crank, h beam rods and 9:1 CP pistons and as a street driven car its amazing. the torque is fantastic with the AWD. I can def say if you build a 2.3 you won't regret it! good luck

I'm a little confused on the bore OR stroke part of the question. If there is damage to the cylinders, it will of course need to be bored. But boring won't gain you anything and it's best to stay as close to stock as possible. Stroke is where theses engines gain power and spool time. Higher compression means more power all around and faster spool as well. So if you have the ability to go with a higher compression 2.3 stroker then by all means do it.

What you will want for a stroker is a 100mm crankshaft rather than an 88mm like 2.0's use. Many reputable companies sell these including Eagle. You will also need pistons with a 6mm offset wrist pin since your using a 2.0 block. Wiseco offers these in a few different compression ratios as well. The rods can be the same length as 2.0 rods so any 4g63 rod of your choice will do. I would suggest Eagle H-Beams. This would give you a fully forged stroker bottom end for around $1500.

But there are other things to consider. If your raising compression higher than 9.0:1, you should start looking into alternative fuels such as E85. You also have to consider what turbo you will be using. Strokers spool turbo's faster, but also require more airflow due to the larger displacement. So just be aware that strokers do have some extra needs. And since you have a 6-bolt, you always have the option of just rebuilding it to stock. 450-500hp would be cake to a 6-bolt engine. So it's just a matter of what you want and how much your willing to spend.
