I could not find this in search...which everyone here knows the search sucks anyway. Nevertheless, I was wandering if anyone knew if there was a transmission set up for a rear wheel drive vehicle that will bolt up to an Ecotec. I won't say why because I know I will automatically get flamed. But could someone help me here.

Well 1. the search is good if you are smarter than it
2. not that I know of, but it's been done using transverse mounting
3. I think it's obvious you want to make a rwd ecotec

If you are wanting to make a rwd j-body, I wouldn't worry about the transmission until you figured out a way to tunnel a driveshaft and find a rear axle that fits, let alone mounts (planning out brackets, suspension, etc) in between the wheel wells. After you get that far, let me know how you figured out the steering system...

Buy stuff from CarCustoms Ebay! Won't be disappointed!

If your going to make your car RWD I'd recommend a cage. Then you'll have mount points everything you have to alter. Also then you can cut out the center of the car out and not have to worry about the uni-body structure failing. For the trans try checking out "Transdapt" I forget the web site I know they're still in business they have ad's in super chevy, car craft and what not. They make adaptors for all kinds of engine and trany combos.




Driving a busted-up 03 cavy (damn black ice 3yrs ago!!)
Got a front bumper last year, just too lazy to paint it, and put it on

My (Original)90 Z24 is now being retired
Way too much rust Maybe it will become a V8 or something very wrong (4x4)

Picked up another 90 z24 from the west coast no rust!
But a rod bearing is spun. I got a motor, just need time!

Man do I ever miss my 3.1 V6

Solstice or Sky roadsters.

Aisin AR-5 (Solstice/Sky) will bolt up. If you plan on using it in a J-car...hope you've got a deep wallet and a welder.

well, actually, I'll be honest. I know where there is a totalled ecotec cavalier and i picked up an 87 2wd S10 Blazer with no motor transmission or fuel cell for $275 US. I saw an article where a guy on here had an ecotec in an s10 dirt track truck and i cant get him to answer that question. I figured that if I can get the car cheap (which considering where it is, I probably can.) I may as well try to stick it down in there. I mean, I will be cutting the truck up a lot anyway so, I may as well go for it. But thank you Quick and Zline for that answer...and thanks guys for not ragging me too hard...BTW, Pilz, I love those headlights. My neighbor has a similar set in his Fire.

Sounds like a fun project. With everything else GM has thrown into various trucks over the years, I'm surprized they never put a DOHC 4 banger in the S-10 pickup.

Not trying to discourage you, but simply advise you about a few things here.

The blazers from those years came with either the 2.8L V6 or the 4.3L V6. '87 was the first year of the 4.3L, so it probably came with one of those. Both those motors make all their torque at lower RPMs. Take the 2.8L V6, which made 148lbs/ft @ 2800 rpm(going by memory here, might be a tick off), where as the Eco make 146lbs/ft at 4400 rpm. Although the peek numbers are nearly the same, the rpm at which they occur are significantly different. This difference would make for drastic drivability issues.

The solution would be additional gearing, probably in the 4.10:1 + range (available from some 4cyl S-10s in salvage yards), which would mean some seriously high cruse rpms, depending upon the tire size and the gear ratio you use. Another option to look into would be building a turbo kit, you would still need more gearing, but not as much.

As for transmissions, a manual transmission, if it's an internal rail tranny, might be a problem. If its from a car such as a Solstice or Sky, the shifter location is further back on the casing, than a truck type tranny. Just look at the T-5 that came in the S-Series trucks and the F-Bodies, while most of the internals were interchangeable, you couldn't swap the cases. (I swaped the 0.84:1 5th gear/OD in my S-10 for the Camaro's 0.76:1 5th gear/OD, made for much better highway crusing.) As for an auto tranny, I don't know what bolt pattern the Eco's use, so I don't know what would match up.

Getting an Eco to work in those older truck would be a cool mod. Good luck!

dont forget, they also had the 2.5 in the blazers as well. LOL. but it really would be cool to have the driveability of a daily. But the truth is, I am gonna be doing most of the driving on and off a trailer or with the frame on the ground. It will primarily be a show truck...and I know popping the hood to display a fully functional Ecotec will drop a few jaws.

This Blazer means a lot due to the fact that it is a replacement of an 87 S10 that was more/less stolen from me. This is a truck that is probably gonna take about five years to complete. So, I've got a little time to figure this all out. But I was actually considering the torque factor anyway. I was thinking of checking out some of the old 1.8 S10's from the early 80's to see what gear ratio they had in the rear end.

I noticed you mentioned wheels and tires. I will be running a set of 16x8 (4 1/2 backspace) old school Boyd Whittiers with 225/40s in the back...in case you are really good with tire sizes and gear ratios...as u already seem to be.

Now here is a really good thing. I am going to be pulling the dash out of the Blazer and replacing it with one that is mostly just a shell shaped like the original. This will give me plenty of room to hide a majority of the electronics you see when you open the hood on a jbody. (Especially considering I am pulling out all of the duct work from the heat and air.) Therefore, with a one off dash, I can maintain all the electrical components that the Ecotec needs while integrating the Cavalier gauges into the truck....I can even build my own fuel cell that uses everything for the factory Cavalier gas tank.

And as far as the shifter, I am sure that's nothing that I can't cure by a custom bent rat rod style shifter.

ok not stealing your thread here, but just had some thoughts for ya. ok they are saying the 5 spd in a solstice will bolt to a 2.2 ecotec to right? ok well why not keep the fabrication to a minimum and take the powertrain and drvetrain and drop it into a a smaller RWD car like a chevette for instance? it is possible to buy the car, engine and tranny, misc. custom parts, and all fabbing, to drop a 500 big block from a 76 caddilac into a chevette for 2000 dollars that is being you do the fabbing yourself. so really all youd need is custom mounting points for engine and tranny, wiring to sort out and a custom drive shaft. that would be the basics really for a chevette drop in. of course there would be other things to work out but a little more basic to do then turning a FWD to a RWD.

just an idea for ya. its something ive thought about myself, would be a fun little car and a sleeper at that especially if it was boosted

Bigari...please dont think Im being an @$$clown with this response...the reason being, the 87 Blazer is something that will have to be pried out of my cold dead hands and is really something I have to build out of pride and nostalgia for my 87 S10 that got BASICALLY stolen from me. So, if I put an Ecotec in something, it will be the Blazer. However, that may be a good idea for someone else. I still haven't gotten to look around for a rear end for it though.

yhsy brings to mind another thing, the slipyoke for the driveshaft. Do the Solstice/Sky cars have a regular RWD type driveshaft, that you could get a driveshaft off of, cut the tranny end off, and weld to your Blaer shaft/new custom shaft? Stupid of me, but yea, anyways. Might have to gear up (numerically) the rear end too to make up for the lack of low rpm torque so you don't cook the clutch on/off the trailer.

i hear ya no offense taken it was just an idea and maybe an idea like you mentioned for others wanting to do a RWD ecotec powered car later.

Greg, from what I am told it is simply a RWD tranny. Now as far as hooking it to the Blazer, I would imagine I could use the forward section of the Sky shaft and graft into a custom length shaft for whatever rear end I find to swap to.

An Attempt to help:::I don't know crap about trucks so I'm going to go Nissan for a sec here: If your truck can handle the power (I'm sure it could). When swapping a Nissan 240sx to a Nissan Skyline motor, most people cut the yoke off the skyline and have the yoke welded to the 240sx driveshaft. That way they use the stock shaft and rear end. Here is an example copied and pasted from a web site of what i'm trying to say.

Driveshaft
The RB25's transmission is slightly longer, and the output shaft slightly larger than the 240SX, so a new driveshaft is needed. If the Skyline's driveshaft yoke was included in your clip, slide it into the transmission and shove it all the way forward. Then bolt the stock driveshaft to the differential and let it hang. Measure the distance from the center of the U-joint on the diff to the center of the U-joint on the back of the transmission and--this part is important--subtract 1 inch to allow for driveline movement. Take all the pieces to a driveline shop and tell them "I want this yoke (Skyline) and this rear U-joint (240SX) on a one-piece driveshaft this long (your measurement)." Then give them money (probably a few hundred bucks). If you don't have the Skyline yoke, you can use one from a twin-turbo Z.

Brandon, you are thinking exactly what I was thinking when I said that. Sometimes I'm just not as tecnical as I need to be...LOL But yes, that's the way I plan on doing it but. you certainly took the explanation to a whole new level. And thank you for doing so because some people may not have known what I was talking about otherwise. Now the issue is finding the right rear end with the right width and gears to match up to make the Blazer somewhat streetable if I do happen to want to cruise it.

I'd try to get a rear out of an S10 pickup that came with a 2.2, as it will have 4.11 gears in it.

Well, I dunno, it might just be certain years.. My 2.2 has a 3:73 from the factory. But I have heard different things. One thing definite, I would like to use something from an S Series so I dont have to worry about bolt patterns or backspace issues tucking the 16x8s...I'll have to look into that 4:11 deal. If some of them had those, I know a junkyard with massive amounts of S trucks that I can pull one from. JBO meets an officially antique Blazer LOL (God, it feels weird calling an 87 an antique but, it is 20 years old.)

5 more years on the antique thing.

For the 4.11 gears, I had a 98 with a 2.2 and it had the 4.11. Maybe start there.

I may be mistaken, but I think that the tranny in the Solstice/Sky is the same as in the new Colorado/Canyon trucks (obviously with a different bell housing).... I had a really good train of thought going there, and it completely left me. I need to go to bed.
BTW, what Eco are you planning on using? the solstice/sky come with 2.4 ecos or 2.0 turbo ecos, already set up for RWD use. using a 2.2 eco from a FWD car can be done, but it would prob. be a little more work. I suppose if there's a real big difference in price (favoring the transverse 2.2L) that is the only reason I can think of to use that one...



LD9 F23 FTW!!

HAHA! Knowing my luck, by the time I get it in paint, it will be an antique by both standards. Dang, maybe it was just pre 98s that had the 3:73's I got a 98 (almost a 99 from build date) but, that thing is my baby...LOL I'll have to check that out and grab one outta the junk yard if it is. Now as far as the trans being the same as a Canyon/Colorado except the bell housing, I dunno. But my buddy broke the tailshaft off his Colorado and it took him three months to find one and get his truck back on the road. As far as using the transverse ECO. YES, there is a big price factor. I own an 04 Cavy and a DIRT CHEAP local junk yard has an entire 03 Cavy with everything still in tact with the exception of the crushed body panels....I was thinking I can use the car as both a donor for spare interior or what not for my car and the motor and all that for my Blazer. I dunno. Sheww I got so many hands in the fire it's pitiful right now.
