I have a rear half tub and fuel cell so that wouldn't necessarily be bad thing. The thing that would hold me back is the fabrication cost to make it fit.

I think he wants to run another set of pipe on the passenger side. The underbody isn't notched out like the driver side so he may have clearance issues.

It would probably be a better option in a coupe cuz they're quite a bit lighter in the rear than the fastbacks. I've never seen one of the t-56 transaxles so I don't really know how big they are. I've seen lots of the rear mounted vette automatics, but never a 6-speed.

the vette t-56 transaxle has the same trans housing as a regular t-56 transmission i believe. ive seen some pictures, and it just looks like it is the transmission bolted directly to a diff.

ok question, what kind of clutch's yall using, what are some good one's were could i get a lightweight flywheel, or does it even matter?

*edit*
got another question, the difference between the flywheel teeth, like 168teeth to 154 teeth or what ever, is that just due to having different years from the sbc 350 or the difference in like starters etc..

has any body used the mini clutches?

Which engine are you asking about?

I'm using an LS7 clutch and LS2 flywheel on my LS1. About the same weight as stock and the same pedal feel but with much much more clamping force.

There's TONS of race clutch options for chevy's. They look similar to a tilton triple carbon clutch, but not actually carbon and much less expensive. If you just do a quick search on google you should find plenty to choose from.

I'm using a Sachs OEM clutch for now. I didn't want anything more aggressive because I've already exceeded the GM factory torque rating for the T5.

Car goes on the dyno today. We'll see how much it's pulling out.

Neejay

Sweet! Be sure to post back here!

g6civcx

Jegs engine package 1 = $2200 shipped: http://www.jegs.com/p/GM+Performance...10002/-1/10763

Block hugger headers. 2-1 Y pipe. PDM Racing high flow S13 cat. Open side pipe no muffler.

Today on a Dynapack it made at the flywheel:

220 bhp @ 4500 RPM
295 ft-lb @ 2000 RPM

No, that's not a typo. Peak torque was two hundred ninety five ft-lb at two thousand RPMs.

Neejay

Is that below, at, or above your expectations?

g6civcx

For $2,200, granted it doesn't rev that high, the torque blows away anything I can buy new or used at that price.

holy cheeto's

Dyno plot of flywheel torque. This is before correcting for parasytic loss. So I'm guessing the motor is putting about 350 ft-lbs at the crank.

Baseline run with no mods on a $2,200 crate motor.

Blown240sx

My 408 motor was the same way

I made peak torque 430 ft/lb @ 3500 little higher but @ 2000 I was making 350 lb/ft. Peaked out at 430 hp @ 5600

I have to say its hard to go back to the import motor having so much off idle torque.

There is really no difference between low and high end torque. If paired with correct gearing, either motor will work well when in the power band.

The problem is that it takes longer to get into the power band and is easier to fall out of the band if you're not careful. So starting out and driving requires more planning with a peaky motor.

I've got a T-56 from the C5 Corvette. Will it work for the LS1 swap into my 1991 Nissan 240SX hatchback or must I have a T-56 transmission from a F-body?

blu808

No the c5 uses a transaxle in the rear of the car. The only similarities are the internals.

Sorry.

Technically I haven't taken delivery on the Corvette T-56 yet .. was due to pick it up in 2 hours, so I can back out of the deal (cash deal). Thanks for saving me man!

irax

I hate people like you sooooo much

I'm sorry if I ruined this thread with that comment


Thats soo freaking awesome it must just love roasting tires up to third gear.

yea tq is fun. my fd made

330 pnd ft tq at the wheels at 2000 rpm
and then shot up to 388 pnd ft tq and held all the way to 6500 rpm.

That's very nice. I can make pretty much the same torque, but this motor can't hold the revs for nothing. After 4,000 RPM I may as well shift cuz I can make more thrust at the wheels in the next gear than staying in the same gear

On2

Textralia, McLeod, SPEC, Exedy, Zoom, RAM make some pretty nice twin disc clutches. I want an Exedy but will likely go with a Textralia.

Sir

I want Exedy as well, but mine already came with SPEC setup and light flywheel, so I'm keeping that.

LS6 clutch is a popular option but the flywheel is like 50lbs.

I'm running an LS7 clutch on my LS1'ed S13. When I got the clutch it felt VERY heavy along with the flywheel. But I really don't notice the weight difference when driving it (compared to the 3 SRs and one KA-T's I've owned). The torque from the LS1 just out powers it. It's an amazing feeling. It's so linear, regardless of a couple extra lbs on the flywheel/pressure plate combo.

I've been researching this swap for the last 2-3 months... I bought my S14 last fall and was going to go SR but after researching that it seemed like a whole lot of money for not much benefit over stock... Researched VQ, KA-T, RB, an 2JZ, asked everyone I could find who already owned one of those cars what they thought about it... problems etc... After all that there was no doubt that LSx was the best swap option for the kind of car I wanted to build (300+whp daily drivable with same or better than stock weight and weight distribution and will cost me $7K or less to do). Lots of people have given me lots of reasons why they don't like LS1 swaps... I did my research and I'm satisfied with my conclusion...

My thread on LS1 tech: http://ls1tech.com/forums/showthread.php?p=9072887

One member even provided a spreadsheet with a bolt for bolt breakdown of his costs to do his swap completely custom (~$7K including the motor)... there's lot of other good info there too.

but enough about me...

Anyway I spoke with dozens of people on LS1 tech and they all really hated the Hinson kit... Personally I don't see anything wrong with their kit. IMO it's a bit pricey for what you get and I'm weary of anything that requires cutting away a major support member. But I'm not one to make a decision without looking for all the possible options available.

After reading through this entire thread I'm quite surprised that the ALTERNATIVE LSx swap kits weren't mentioned at all... I looked into the Hinson kit and I also looked into the alternatives on the market.

Some of the other LSx Kits:
Daft Innovations kit for the S13 (and soon for the S14):
http://www.daftinnovations.com/s13ls1/index.html

Skky kit for the S14 (and soon for the S13):
http://sikky.com/products/mount_kits

I didn't look into the daftinnovations kit much but the impression I got was that instead of modifying the cross member they modifed the GTO oil pan and some other modifications with the sway bar I think... but the SKKY kit looks like THE way to go for S14 owners... I spoke over email with their tech at lenght and I'll be using their kit for my swap... it's just barely been released and only to a small group of pre-order customers.

you can see a picture of the kit here:
http://www.d-rated.com/public/images...complete/5.jpg

basically the skky doesn't modify the front crossmember AT ALL nor is there any tranny tunnel or firewall modifications needed, or any spacers... or any of that junk. Instead they built a 100% custom oil pan that clears everything in an S14... it holds 7QTs of Oil AND has the benefit of traps and baffles so that the engine doesn't suffer oil starvation when it encounters long periods of lateral movement (eg: drifting/hard cornering) since the GTO pan wasn't designed very well for that application. They claim the engine sits lower and farther back than any other kit. I don't have any measurements but comparing pictures from their site to those of other kits it seems to have some merit... either way a reasonably priced kit that includes nearly everything you need and doesn't require modification to install, and adds some upgrades to the motor at the same time sold me...

What the kit ($1700) includes
-Custom Oil Pan
-Engine Mounts (with a eurothane cushion)
-Remote Oil Filter Relocation kit
-Transmission cross member and mount
-Steel Driveshaft to bolt a T56 up to the factory rear end (can be upgraded to Aluminum for an extra $200)

I'm not just here to parade their kit though... I just wanted to present it to the forum as an alternative... hopefully some of that info could get incorporated into the top post...

Some Questions I still have:
-Are there any Y-Pipes on the market that will bolt up to a set of S14 compatible headers and mate up to the factory S14 cat location? I've seen a few headders mentioned but everyone seems to say that Ypipes have to be custom made
-What is needed to get AC and heat working?
-What is needed to get power steering working?
-What is needed to get the factory gauges working?
-I've seen people talk about upgrading to a walboro fuel pump but wouldn't you also have to upgrade the fuel filter? What about on the engine end? does the LS1 have a FPR that can be used? Anything needed to adapt it to the LS1?
-What about other amenities such as Cruise Control, how do you get those working?

Some of these questions have been brought up before and lightly discussed but IMO the answers have been dodgey at best... mostly just people saying "you can make it work" with no real straight answer as to HOW...

Anyway this is a great thread and despite my prior research I did learn a few things reading through it
