Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

I loved looking through this thread. It's basically everything I'm planning on doing. I also LOVED finally seeing some Trac Pac torque arm pics because I plan on doing the same!

S&W also offers the same style torque arm that attaches to a crossmember between subframe connectors.

http://www.swracecars.com/store/Adju...75=40-601.aspx

http://www.swracecars.com/store/82-9...74=40-604.aspx

$333 total for the torque arm and crossmember. Of course you'll need SFC's to weld it to.

Tell me about your ground clearance. Any bottoming out? Is the car lowered at all?!

Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

Ground clearance isn't too bad. So far Ive only bottomed out once, and that was when I first drove it. There was a dip in the road favoring the passenger side, and didn't think anything of it. Barely scraped the bottom of the xpipe. Put new stock springs in the rear and haven't had a problem since. Sportlines in the rear where to low for my taste anyway. Still running Sportlines in the front though. If I had to redo anything, I'd tuck up the exhaust better.

Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

i believe you are getting high iat's because the pipe is aluminum and the iat sensor and maf soak the heat also.... i fixed this with a plastic intake setup and relocated my iat sensor... no more problem, whatever the outside temp is is what the computer sees. i also haver a heat shield too but it doesnt look pimp like urs

I have a 3" Strange steel drive shaft. What do you think the torque arm clearance would be like?

Went to replace the pipe with a silicone piece, but the od is to big to fit through the shield. For now I'll leave it, maybe wrap it with some heat sleeving or something.

Couldnt really say, but maybe these pics can help. It would also depend how far up you tuck the bmr crossmember.

Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

Im stoked, Kyle and TMS have been great so far.

Im stuck on what cam to run. Was impressed with the previous AI cam, but felt it was a tad to small. Looking at:
BTR's stg III: 231/242 .617"/.588" 112+2
Tick Custom: 227/237 .614"/.610" 111+3

or suggestions?

Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

I dont know how...but Ive missed this entire build.

Im really impressed! You do some great work! Im digging your exhaust. True duals is something Ide like to switch to at some point. There was a fella over on tech that did a really nice true dual set up, complete with cut outs...and I was going to try to model my set up after his. But it looks like a lot of work haha.

Stinks about the motor. What happened..any idea?

Oh man so many things I wanted to comment on haha. Too bad I missed em all. Good luck with the new motor! Looking forward to hearing how you like that TMS build. Tick's cam's seem to do well. But, Im a BTR fan. His spring kit and PR's are awesome, his prices are good, and he's a darn nice guy to talk to. Can say the same thing for Tick though...so thats a tough choice

Thanks man that means allot. I saw that exhaust build aswell. Def allot of time invested in that master piece.

Was making a wot pull and lost oil pressure. Come to find out it was drinking oil. When i pulled the intake there were puddles of oil on top of the intake valves. Had been running it hard all day and prolly just burnt up too much oil. My fault, but that wont be happening again.

Tick seems to be the hot sellers at the moment but I went with the BTR stg III.

Re: 1986 IrocZ LS1/T56 Swap. Start Up Vid Added

I dont think you'll be disappointed with the BTR. That guy seems to have his stuff together and makes quality parts. I kind of wish I went to him for more of my parts now. Cant wait to see how the new set up runs for ya!

I had lots of blowby on my LS1. Puddles of oil in the intake, etc. I had a catch can installed, and it didnt seem to catch much. So I dont think I was using THAT much. But I havent pulled my intake tubing off to check on the new motor haha. Im kind of scared. If I see oil, that means my ring job isnt sealing any better than the last motor. We'll see.

Bummer she popped but on to bigger things for ya!

Well its here.

Need to decide on a timing gear set and which lifters to run. Plus a bunch of other parts still need to be ordered. Hopefully I'll have everything by the weekend.

questions for you, im swapping a 98 metal tank with the separate evap stuff, do you know how i would plumb my car to the 98 tank??
the 98 pump has 4 lines coming out. im guessing 1 feed, 2 vent, 3 return and 4 purge? can i vent the purge line and do the 't' setup like yours as the return??
