wingsfan, u should be a teacher, thx for the help!! :P
u got all your stuff from hinson?

wingsfan

I am, sort of. I work for the University of Texas.

I got the mounting hardware, bump steer correction, torque arm and driveshaft from them. Everything else I did on my own.

Is there anywhere in particular everyone is buying their motors from?? I would like to make sure i am getting a setup from a dependable source....or is everyone getting them from EBay/Junkyards??

oh, i cant weld sh*t..
good for you

An FMIC would work with a centrifugal (Paxton & Vortech) or Lysholm (Whipple) supercharger, but an FMIC would be really lousy with a Roots (Eaton) blower. The Roots blower is better off with an ALIC, or you can just run it without an intercooler since Roots blowers are only intended for low boost, anyway.

The GM unit may not work well with forced induction. You may want to see if anybody else has had luck with this before starting your project.

It's kind of a moot point since thre's no roots style blower for the f-body. There's one for the vette that will fit the motor, but it's never clearing our hoods and IIRC it needs the FBW c5 throttle body to work, which would be a major headache to adapt.

Best bet with a blower is to run an ATI procharger, or a Vortech unit. Turbo is the better choice though for FI, but I'm more than a bit biased.

It will work just fine. You just need the right software to reburn the pcm.

Need is such a relative term there. The turbo buicks are V6s and they use singles.

Most people in the LS1 community run single turbos because of pacakgng limitations. They seem to work just fine, and to say they're only good for drag racing setups is just flat out wrong. There are plenty examples of single kits out there that are great for everyday use.

A 5.7L engine moves enough air to where lag isn't a real problem, so street use isn't a real problem either.

*edit* BTW, the fastest turbo LS1 these days is a twin setup (8.29s @ 170), so I'm not disagreeing that twins aren't preferrable, just that we (FDs) have major packaging constraints that make them a poor choice.

roots sux for the type of setup im expecting to run, i am already into vortech aftercooled supercharger which gives you around 150hp and tq boost, with a stock setup.

do u reccomend turbo instead of supercharger?

i was told for an ls1 fd turbo kits needed too much of custom fitment, but the supercharging was easier, just in need of customizing the piping.

i was told GM works good with LS1.

i have a friend who is selling me the aftercooled vortech SC made for a Z28 00+ for 2800.. figured it was a good price..

If your talking ls1 FD that supercharger kit is gonna be hella custom to get it to fit. their is one guy that got an ATI charger in the ls1FD but he cut the firewall and moved the engine back and maybe a little more modification. Either way you go with these cars its conna be custom

ebb

I noticed the guy who moved his firewall had the supercharger pulley facing the toward the rear of the car. That necessitated moving the firewall for space up front. Would it be possible to mount it the other way around where the a/c compressor is located? I don't know anything of the dimensions or what side the intake goes in so I am just questioning if it would make it possible without moving the firewall.

Skele4door

Does anyone have pics of the guy that crammed the ATI blower into his FD? I've never heard of this and would love to take a peek at what was involved.

try searching on torquecentral under the name cdk4219, he doesnt post much these days but checks often. the supercharger post was make when i first signed up @ TC around 06-2003 if that helps

hey
did a quick search and found the thread

hmm, looks squeeshy...
maybe making the motor mounts lower, lowering the engine and making all the piping on top?
the ls1 engine sits nicely above grounbd, maybe with a strut bar it wont be any problem pulling it down a lil bit.

wingsfan

Well, there's not much room in there, so regardless of what you do it will be a tight fit. A turbo will fit behind your radiator just fine though, provided you use pusher style fans. You're only a set of custom manifolds away.

Lowering the engine is going to be tough. You already have to drop the steering rack about 5/8", and then compensate for the increased bump steer with adjustable tie rod ends. There's only so much that those can do though, and with the Hinson setup it looks pretty close to taxed to me.

My advice would be to just get the motor in the car first, and then figure out where you want to go from there. IMHO making plans based on pictures you've seen on the internet is a bad idea. It's much better to get in there and actually measure the space, and get a feel for how much room you have.

owen is fat

screw that! my advice is to buy an FC!!!!! there's tons of room in the FC engine bay after an LS1 swap! slap on some widebody fenders and go racing.

RageRace

I thought that someone(or more than 1) was in the 7s with an LSx, full race of course, no???

Packaging? The twins will fit.......

wingsfan

Ronnie Duke is in the 7s with a supercharged C5R block, IIRC. Sort of a second cousin to the LS1.

I have yet to see a 7s true LSx motor, but that doesn't mean it hasn't happened, just that I haven't seen it. I might have missed it, or they may not post on the boards.

There will likely be a handful of LSx based cars in the 7s this year as the racing season gets started. It's still early in the year, and some people are still under snow.

A) You're not using an LSx motor
B) You kissed the stock hood goodbye awhile ago.
C) Anything is possible with enough money thrown at it.

I'm in a long haul for 20b swap in an FD. But seen many of Hinson's LS1 FDs and man.. Everytime I see one, i'm thinking about doing one.. Good gas miles and good torque.

Just to plug Hinson Super Cars, They do an awesome job. I've seen several cars they've built and they all look to be done right. I've also seen one Ls1 swap that someone did themselves and it was crap.. ended up going to Hinson's to be cleaned up... I believe that car was built in Miami, FL..

I'm more and more leaning toward LS1.. maybe once my daily goes dead (Acura) I'll consider LS1.

Hinson and his crew will be at the Deals gap event in April.. Come out and talk to them.. They will be bringing a surprise car.. most likely.

But didnt hinson JUST post pics of their twin setup???

wingsfan

Yup, and you can probably see that it's not the most street friendly, nor nondestructive build ever.

It's got a couple things going against it.

First, they cut the firewall, which is something I'm not willing to.

Second, they're running an Air-to-Water setup, which is great for a quick trip down the strip where you can just add some ice to the container, but pretty impractical for daily use.

Lastly, IIRC he's running a powerglide, and there's no way I want to jet around town with two gears.

I'm just saying it's impractical, not impossible. Different strokes for different folks. I'll stick with my single, intact firewall, and an air-to-air with methanol injection, thank you.

wingsfan

How's this?

7777 Nepok 7777 -rx-

the fmic isnt really necessary for an ls1, right?
how big is that?
looks sooo nice though

wingsfan

Correct. The intercooler doesn't care what engine or turbo it's associated with.

Thanks.
