Topic: 2.6 stroker

[4.3s10]

so what you guys think would be better the 7mge swap or 2.6 stroker. I'm not sure if the 7mge is  the type of motor that would be good for crawling it just seems more high end and i don't think the swap is worth it. I think it might just add up fast for parts and the stroker kit seems better for what we want and it is cheaper than the whole 7mge swap. Any info is great.

7mge. do you really think the 2.6 is a bottom end motor

[4.3s10 [OP]]

hmmm... it just seems like the 7mge would want to be at higher rpm more it just seems more of a racey motor than a crawling motor.... but i guess not

[brainlessfool]

I looked at doing the 2.6 strok when I rebuilt my motor, butt did not want to drop the 1.8K lc wanted for it.

for 1.8 K I could drop in a 4.3 chev.

yea 1800 is a lot for a rotating kit we payed 1100 for a rotating kit for the 383 stroker... the bottom end torque on that motor is great though. Are there any other companies that do the stroker that are maybe at bit cheaper

[brainlessfool]

   I did not find one.

[kyle_22r]

it'd be nice to see a cheaper alternative come out.  especially since it's only a 4 cylinder, $2k for a rotating assembly is obscene.  i'd look into it if you could get a modiifed crank for $300, hell even cast could probably work ok(as well as being cheaper/easier to produce).

probably never gonna happen though...

[4.3s10 [OP]]

what do you mean by a modified crank? and are there actually places that do that? I think a cast crank would be great i honestly don't think you need a forged unless you are making serious power or running at high rpms

[kyle_22r]

the stock 20R/22R cranks and rods are forged.  the strokers are made by welding up the journals and re-grinding them on a different center so the journal gets more of an offset, thus increasing the throw.

[79coyotefrg]

my crank was custom ground and the rods resized to give me 91mm stroke,      for $200 ,   honestly its not worth the 1800  in my opinion,for the stroker kit

  get the heavy flywheel  and run a stock crank

the 7mge  is like 180lbs of torque at like 1800 rpm,    but they are much heavier than a 22R

[4.3s10 [OP]]

hmm that intersresting ill have to check that out... do most machine shops do it for you

were your rod shortened or lengthend

what do you mean by heavy fly wheel and were can i get that

7mge. do you really think the 2.6 is a bottom end motor

i had an lc engineering stroker in my 85, all hand built, produced 195 hp with a 500 cfm carb, and 235 lbs of torque.
it was comperable to a v8, and in low range, i could pull the tires off the ground in second, it was a really mean motor, idled faily well, and made gobs of useable power at about 1800 rpm. it was well worth the arm and leg i paid for it in my opinion, just thought that i would chime in

[4.3s10 [OP]]

that sounds like a sweet motor what else did you do it

[crawlerdan]

it had a cutom high flow intake, a 5oo cfm holly carb high flow filter, ported and polished head with ti- retainers, double valve springs, REALLY big valves, i forgot how big, they where ridiculous, a custom ground cam, it redlined at 3200 rpm, made peak power at 1850.
a stainless steel header into 2.5 inch stainless pipe, no cat, no muffler. it was bored out to fit small block chev pistons, i think .45 over, maybe .40 had a over weight forged crank that increased size to 2.67 litres, forged h beam connecting rods, high flow oil and water pumps, high flow fuel pump.37lb. flywheel with custom made centerforce "clutch": tho it wasnt much of one..hehe...had underdrive pullys, adjustable timing gears, a pro billit distributer with mech. advance. 8mm wires with an msd 6a ignition and msd ignitor. no smog, no egr, remote oil filter, the damn thing idled at aroun 1100 rpm, i could drive it on the street if i could avoid using the clutch too often.
it was dynod at 187 hp at 1850 on 91 octane pump gas, and 235 lbs at 1600rpm

all at the lovely cost of 7200.00.....worth it? it wasnt until i pulled a 39 inch swamper a foot of the ground at a stopl;ight, then it was worth it!!! all that power was sent to a toy turbo trans an three cases going to a gm 12 bolt and d44, i miss it dearly!

[4.3s10 [OP]]

wow  that is one sick motor i like it a lot thats a pretty radical build... do happen do know the specs on the cam

now why did it redline so low was it just the stroke was long

when you say that it lifted a tire off does that mean it did a wheelie

i had it designed so that it made all its power down low where i needed it, it was a truggy
i dont recall the lift or duration on the cam, look at a stage three trd, and add a little to each, they where real close
and wheeli, yes, yes it did, but only in low range, in high range it would leave a couple feet of 14 inch wide rubber

[kyle_22r]

hmm, just noticed this:

http://www.toyotaperformance.com/crankshaft_kits.htm

$475 for a stroker crank...intriguing.  i'm seriously starting to consider selling my 20R/22R hybrid and building a late model 22R or 22RE stroker with a heavy flywheel...
