Need some info on 2.3 stroker kits

[Race94]

Well my 95 GST 7-bolt either spun a rod bearing or is getting crankwalk, i don't want to put in a 6-bolt cause it'll be too much trouble and cost around the same as making the car a stroker.

I have a few questions tough:
1) Will i be prone to crankwalk with a 2.3 stroker??
2)What should a stroker kit consist of? where did you get it? pay for it?
3)What needs to be modified?
4)What should be upgraded too, so it's safe?
5)I have a GST, haven't heard of many FWD doing this.
6)How hard is it to install?
7)What compression is better on the pistons? What brand pistons/rods should i look out for?


Thanks!

1. If you use your 2g 7-bolt... yes.
2. Crank from a 2.4L 4g64 and custom pistons, you can use your old rods, but I'd suggest at least getting some eagle rods.
3. Just the aftermarket pistons need to be added, and a little clearancing on the deck and main girdle to clear the larger crank... It's easily done with a grinder or dremel.
4. Rods, ARP main and Head studs, metal head gasket, deck the block, bore/hone the block, all the other stuff you'd do when building an engine...
5. OK, be one of the few...
6. No harder than a 2.0 engine. The only thing you're really changing is the crank. (this depends on your mechanical skill level...)
7. 8.5-8.8:1 is pretty much standard for a built DSM. Mine is 8.5:1. I believe wiseco, JE, and one other company make the stroker pistons. As far as rods go, about any aftermarket set will do. Get some good bearings too... (clevite77)

This is a thread of stroker setups

 

[Race94]

did you buy it as a kit or separate??
is yours a 7-bolt?

 

[99EclipseX]

I also have had this same question over the past few months- Just felt it was too dumb to ask a shop- Now the most important question you had was WILL THE 7 BOLT WITH A STROKER KIT STILL BE PRONE TO CRANKWALK- I think it still will be but I'm not sure- What I also would like to know is what more would you need to rebuild a 6 bolt beside the stroker kit???? So the question is when my 7 bolt crankwalks because I know it will- If I buy a blown 6 bolt and a stroker kit what more would I need to make everything work

 

[trevor0587]

dont go bulding up a 7bolt. a 6bolt block is only around $100. if you do end up bulding the 7bolt i think you will end uo wishing u whent to a 6bolt. just my 2 cents.

 

[Race94]

but can you just swap in a 6-bolt block on a 2g??
Doesn't anything else need to be modified??

Why would a stroker walk? Isn't the crankwalk problem a problem of faulty crankshaft manufacturing??

 

[bigjangin]

stock parts you can use when swapping in a 6 bolt into a 2g:
clutch, tranny, power steering, ac, alternator, starter etc...

parts you must get:
6 bolt block(whatever internals), flywheel, ...well I'll just post the stuff I got from here: http://www.magnusmotorsports.com/1g2g.asp

# 1G CAS (91-92 Optical Effect, 93-94 Hall Effect)
# 1G Oil Cooler (90-92 MD 157670 6bolt water cooled oil cooler)
# 1G Water Pump
# 1G Oil Pump/Front Case
# 1G Timing Belt necessities
# 2G Engine mount (modified) use 2G engine mount trimmed, with 1G tensioner arm
# 1G Timing Belt Covers (modified)
# 1G 90-92 6-bolt block (with whatever internals)
# 1G 6-bolt Flywheel
# 2G Starter Mounting bracket
# 1G Water Pipe
# 1G lower radiator hose
# 1G Thermostat housing/ Water Neck
# 1G 6-bolt oil pan Balance shafts (remove them or keep em, its up to you, we take them out)

I'm with Trevor. Add to that the fact that the 2.3 stroker FEELS stronger because of the extra torque, but mod for mod it gets slower 1/4 times. I was interested in this until everyone I've read of actually doing it commented on that fact. Maybe straight-lline acceleration isn't your thing. That's my $.02

 

[gregmondro]

what are you comparing it to?
"stock" 2.0l vs "stock" 2.3l stroker?

also what turbos. i'd actually like to see some proof and not just a "it's slower" comment

I picked up 13 mph on 91 octane pump gas @ 4400'with my 2.4L. I did change a lot of other stuff at once, but nothing that would have given me that much power.

Yep, definately FEELS stronger.

 

[karbon]

I'm talking about with stock motor, same supporting mods.

 

[Spellmen]

I've also been contemplating a stroker since I'm rebuilding the engine soon. I have one major question that I haven't really seen answered. Is it foolish to think I can tune a stroker with a 60-1 with just SAFC/GM MAFT? My major concern is that I do not want to go with a standalone like the AEM or Haltech.

 

[ITSME4G63]

Wheres some places that you would be able to aquire stroker kits?

 

[Race94]

is the 7-bolt motor that bad??

i can get a whole 6-bolt motor for around $700, what would i need to do to put it in??

OK, Same mods, 7bolt race gas 26psi 12.4@110. Now put in a 6bolt 2.3 block, same mods as 7bolt, pump gas 93octane 22psi 12.01@114, it so much more torque and faster too.

Is this with using the 6-bolt block and 2g head??

 

[STECARS]

Its using a 1g head.

Please dont spread misinformation. With more torque and hp across the entire powerband, you would have to be retarded to turn slower 1/4 mile times.

[trevor0587]

what i was say was go for the stroker. but if it was me do the stroker to a 6 bolt block that way u dont have to worry about the walk. cause nothiung would suck more that to put all your time and money into stroker your 7 bolt to find out in 6 mouths that the crank is starting to walk. so what im saying is go for the stroker just use a 6 bolt block.
My 2 cents.
Trevor

 

[dsmayhem]

Peace of Mind is a beautiful thing...

That said you would be stupid not to use a 6bolt block being as they can be had for so cheap and it would lessen downtime.

 

[Jahjahpoet]

Ok... me no smart.. But.. If you put in a crank from a 2.4 4g64 engine and did a stroker upgrade to the 7bolt.. what is there left to fear? Are you guys sayin that it will have the same chances as the "stock" 7bolt crank walkin?

No one knows what causes crankwalk. There has been people that have thier 4g64s walk but come to find out it was someone not doing something correctly. I personally am tired of all this crank walk hype. how I see it a 7bolt 4g64 has the same chance of walking as every other car made that uses a crankshaft.

Then you're blind!

I have been a parts manager in central NJ for 12 years and have seen 1 instance of crankwalk! The 97 awd talon only had 45,000 miles on it and was totally stock! My personal beater has over 130,000 miles and still runs fine even with a ton of mods!
