S14 L33 build thread, because I snowed in and bored!

[Gjohnson7]

Alright well I've seen a lot of build threads here on Zilvia lately and I'm bored so I figured I would peice together a build thread. Just so you know up front, I'm on a budget with a wife and 3 kids so this isn't extravagant but I love it and its a total sleeper. The project started in June of 09.

June 29, 2009

Alright, here's the new ride. I picked it up a week ago for cheap from some small dealership that didn't know what they had. It had been sitting there for 4 years, needed a fuel pump and keys. Engine runs and has already been sold. (I just need to pull it)

I decided I didn't want to buy a kit, so I set off to start fabricating. All the work was done it my garage and I picked up a welder on craigslist and went to work.

I don't really have any other pics. Although this is the kit I used.

Also, installed Clutch pedal and master cylinder, swapped in Z06 Cam and Z06 Springs, replaced broken timing chain cover and installed new timing chain kit. Made engine mounts (Currently tacked up, needs to be welded completely)

Engine weighted in at roughly 530lbs, with T56, flywheel and clutch. No intake, vavle covers or accessories. Although the hoist balancer its self weight about another 20 - 30lbs.

Alright, finally got around to pulling the engine again and welding up the Crossmember. Also completed my Tranny mount.

Disclaimer: This is the 1st time I ever even attempted welding and I now have about couple hours of experience. (I have a lot of experience grinding out welds now!)

Tranny mount is not geometricaly correct, by any means. But it is functional and solid.

Just thought you guys might get a kick out of my big rig shifter.


Oh and how are you DBW guys mounting your gas pedal? I need some ideas or suggetions.

Still trying to figure out if I need to send my PCM off and convert to DBC. Apparently the Truck throttle unit is quite a bit taller than the car ones and I'm having issues with shutting my hood. I've already spaced the crossmember down some, may have to cut out some of the hood support. It actually will shut, but the hood is sitting on it and it doesn't allow for any movement from the engine at all.

Sept 9, 2009

Ok, well I know I've kind of left you guys hanging for awhile. So here's a quick update. I figured out my throttle issues and the car is running. I've been so busy lately with my anniversary and my kindergardner starting school and flag football, I haven't even had a chance yet the take the car it's first test drive. I'm still looking for a vacuum diagram for my L33 to make sure I'm setup properly, but everything else is hopefully in order.

I won't know fully if I have taken care of all the gremlins until I can get her down to the gas station and fill her up with 91 octane and then sea foam. My gas tank still has quite a bit of the 4 year old gas left in the bottom.

Oh, still need to modify the hood support to make sure I don't have any issues if the engine gets to tourqing. And I still need front 5 lug hubs so I can put my Z32's brakes on all four corners.

[Gjohnson7]

Jan 18, 2010

I spent hours of time trying to figure out why my DBW throttle was not functioning. Had to swap PCM 3 or 4 times and rewire the harness. Only to find out that the junkyard I that shipped me my tac module and gas pedal lied and didn't pull the parts from the same vehicle. The parts were incompatiable and I has spent litteraly 4 months scratching my head and spinng my wheels.

So, I ditched the DBW, picked up a DBC throttle body and rewired my entire engine harness. Also, had to switch PCM's.

Well, I finally finished making my throttle cable and working through my wiring issues.
http://i252.photobucket.com/albums/hh40/Gjohnson7771/DSC04174.jpg

http://i252.photobucket.com/albums/hh40/Gjohnson7771/DSC04175.jpg

Also, Finally got a chance to take the car for a drive and fill up the gas tank and the car drove like crap! I've got some weird noise coming from the either the driveshaft or the Differential. (I can't imagine it could be the Tranny) I have no idea what the noise is or even how to pin point it. All I know is it seems to make the most noise when the vehicle is under load. If I shift to a higher gear and just coast it seems to go away. It also, seems to make the car jump and hesitate some time under load. Of course it seems to have gotten worse when I pulled back into my neighborhood, and now seems to make this sort of grinding/whining noise all the time.
I guess I may have to see if my neighbor can take a look at it tomorrow with me! Any ideas on where to look first? Since I've never driven this car before, I really have no idea of the condition of the Q45 diff, or the 5 lug hubs. Driveshaft is custom made, but who knows.

Oh, and the exhaust is just modified stock C5 manifolds, 3 inch y pipe, 3 inches out the back with a loud cheap Thrust muffler. Will probably swap to a Magnaflow when I get some more funds.

April 19, 2010

Ok, I have a few more updates. So, I figured out the Diff problem. Yeah, it was a lack of fluid. I guess that's what happens when you work on these projects for months.
Currently, I've been driving the car daily for a couple of months. Right now I'm trying to figure out how to integrate my A/C system before it starts hitting the hight 90's, as well as work throught some new O2 sensor issues.
My O2's were working great, until last week when I pulled a U turn and somehow my driverside O2 wire caught on to the steeringshaft and wrapped itself around it until the wires pulled apart where I spliced them in.
I have since, spliced them back in, but the driverside O2 sensor keeps throwing p0135. When it does that, the passengerside will throw p0155.
Right now, I'm waiting on O2 sensor pigtails from Efi Connection, so I can wire them up properly and see if it fixes my problem.

On to the pics.

A little of the interior cleaned up and some work that started on the quarter panel.
Also, have a small vid but don't have anything rolling without a second hand.

http://i252.photobucket.com/albums/hh40/Gjohnson7771/DSC04318.jpg

Oh, and I just decided I would pull the panel I made for the gauges out and paint it black for a different look. So that's why it's black in the video.

Well after being on the street without any issues for many months. Tranny really started slipping so.....

October 7, 2010

Well, this is where I'm at now. Engine and tranny were pulled last week to replace the clutch, While the engine is out, I had plans to rewrap my engine harness and clean up the engine bay and fuse layout. Then my buddy came over and this happened...
http://i252.photobucket.com/albums/hh40/Gjohnson7771/DSC04845.jpg

I guess paint is coming sooner rather than later.

December 20, 2010

Well, here's a little update. I forgot to update this thread, so I'll copy and paste my updates from the other sites.

The Kouki has been at my buddies shop for a while now and we've been going at it when we have time, but I've spent 75% of all my time working on the rear quarter panel. The only way we could figure to get the fender back in shape was to either roll the fenders or go widebody. I decided to roll/pull the fenders.(figured I could go widebody later depending on how they turned out.) Also, beat on the quarter panels so long we had to torch them and rapidly cool them back down to shrink the metal. Had to cover it with a thin layer of bondo to, to smooth things out.

Well, color is going on but I still need work. I haven't cleared yet because of all the trash that was getting picked up while shooting, so it looks like I will have to sand my base with 800 grit first, before I can clear. That and I ran out of paint. Painted everything but the front bumper.

On with the pics. Sorry, there from my blackberry.

And I'm currently working on wet sanding and buffing. Below are some pics of the process, but you can also take note to my requarter panels which well both have to be resprayed when the temps warm up. Spraying in my buddies garage, when didn't adaquet light and you can tell really easy where the paint on the rear quarterpanels weren't covered properly resulting in light and dark spots. Still need to finish pulling off some of the tape and removing tint from my window. They will be retinted in the spring also.

The first few pics are when I was wetsanding, then a few after buffing with compound. I still have it anything with the swirl remover/glaze.

Thanks man. Car is a blast to drive.

So currently, I'm still cutting and buffing the car. I rewrapped my engine harness and reworked my fuse box/relay layout so I trying to figure out the cleanest install.

I redid my fuel setup, flipped the fuel rail and ran a 14 ft an line from the fuel rail to the fuel filter which was relocated right above the fuel pump.

I still have Z32 brakes, but waiting for cash and parts to sell so I can pick up conversion lines, pads and rotors. Picked up 20mm spacers to help out the stance after the fender roll. Will hopefully be picking up some bigger wheels down the road.

A/C setup should be finished by spring.

[blueshark123]

u should repaint the qp's and also gotten wheels before pulling or panting the car

[Gjohnson7]

u should repaint the qp's and also gotten wheels before pulling or panting the car

Yeah, idealy that would have been great, but I have other priorities. I already had the paint so I had to do what I could.

Like I posted above, the quarters will get repainted in spring.

[Edwin562]

looks great

Heyyy! I sold you the intake.. or some kinda part for that monster.

Looks fantastic man!

Thanks, I love the blue too. Just need to reshoot, cut and buff.

I have been waiting for the perfect blue to come along for me to paint my s13, I want to do the body dark blue, and the roof black. Do you know the name/color code for this blue?

[Tantwoforty]

oh shiz, i can get a l33 for free... i need to get on this.. lots of super useful info here..

[Gjohnson7]

A free L33? I would defintely jump on that. Heck you could pick it up and sell it at the least.

[koenig]

Interlargos Blue. It's a BMW metallic blue. [/IMG]

Thats actually kind of funny, I have been looking at "interlargos blue" for awhile now to paint my car, until I saw yours and I was like "damn, thats even better!!!" hahaha, now I know! It must be fate haha

[Tantwoforty]

well, my brother has one in his silverado, and wants the bigger one so he said if i do the swap for him i can have his current motor.. so freeish.. lol
i have a ka-t thats almost done, maybe i should sell the ka-t and fund the l33 swap lol

[Gjohnson7]

Alright, yall know I'm on a budget, but I picked up a set of used Megan Street coils that just arrived today. Coils are suppose to have about 10k miles on them. I looked over everything and they seem to be in good condition. Then I went ahead and slapped them on. I installed them with the ride height they apparently were already set at, but it looks like I'm going to have to do some tweaking. Right now the front is sitting about a half inch lower than what I would like. I seem to do a little rubbing at full lock and also had a fun time 3 wheeling it coming into the driveway from the test drive.

I was in a big hurry getting them installed, because my garage door came off the tracks and was about to fall on the car. Had to get everthing back on the ground and out of the garage so I can start fixing on it.

[doriNIGHTS]

wow car looks good, good job

[Gjohnson7]

Thanks man. Spent some time tonight trying to adjust the height but I'm having an issue with the driverside bottom mount being seized. Any ideas? I've tried tons of Wd40 and even some heat, but no dice.

[jesse_s13]

Great build. =0

[nate91242]

Looks great, good work sir.

[maxgohan]

gotta rehost the pics

[Gjohnson7]

Any suggeations? Never had to rehost them before.

[Kingbaby]

[shaggy sr]

damn i still cant see pics! u gotta rehost em pics again

[Gjohnson7]

Ok, well I don't have the time at the moment to rehost them all, but these are the most recent. I think the others should be up again when my photobucket account resets.

Actually had to raise the front about 1/4 of an inch.

[SimpleS14]

Congrats on the swap, must be fun to drive.

Plan to lower the rear?

[maxgohan]

what's the difference between an L33 and an LSx??

[StryfeS13]

An L33 is an aluminum block 5.3L instead of 5.7L if i'm not mistaken.

Either way, it is a member of the LSX family and you can bolt on LS1 parts to it.

And I have a question for the O.P, I might have missed it, but where did you find an L33 for so cheap? I've been thinking of LM7, but I'd rather be aluminum.

Here ya go, I found this on GM powertrain.com.

RPO L33 FOR CHEVROLET SILVERADO AND GMC SIERRA
The Gen III Vortec 5300 is available in a new lighter, higher output variant optional on some 2005 Silverados and Sierras. RPO L33 will be introduced in short bed, extended cab versions of these pickups. The L33 features an aluminum engine block, new cylinder heads and a high-lift cam. Torque will increase, and horsepower is expected to exceed 300 in final production trim.

One of the L33’s distinguishing features is its engine block. As with the 2004 LM4 Vortec 5300, the L33’s foundation is a cast-aluminum block with pressed-in iron cylinder liners, similar to the block used for GM Powertrain’s LS1 and LS6 car V-8s. The L33 block is exceptionally light; as a result, a fully dressed L33 is 100 pounds lighter than cast iron-block Vortec 5300s (RPOs LM7 and L59).

The L33 takes its cylinder heads from the LS6. Originally developed for the Z06 Corvette, these heads improve airflow in and out of the engine. With their pent-roof combustions chambers and new flat top pistons (the pistons in other Gen III Vortec 5300s have a slight sump in the piston deck), the L33’s compression ratio increases from 9.5:1 to 9.9:1. This increase improves the engine’s volumetric efficiency yet still allows it to achieve full power with regular grade gasoline.

Finally, the L33 is equipped with a higher-lift camshaft. Maximum valve lift increases from 11.6 mm on the LM7 and L59 to 12.5 mm. The new cam and compression ratio are the primary sources of the L33’s increased horsepower.

The L33 camshaft and cylinder heads were developed in conjunction with the new Gen IV Vortec 5300 (RPO LH6). The design objective was more horsepower for customers who need it, without requiring a step up to the Vortec 6000 (and an increase in operational costs). RPO L33 expands GM Powertrain’s lineup of Vortec V8s and gives GM’s truck customers even more flexibility and choice.

The L33 Vortec 5300 will be built at Powertrain’s Romulus, Mich., engine plant. With its introduction, Powertrain will cease production of Vortec 5300 RPO LM4. The Buick Rainier, Chevrolet Trailblazer EXT and GMC Envoy XL, previously equipped with the LM4, will now be powered by the Gen IV Vortec 5300 with Displacement on Demand. The 2005 Chevrolet SSR will be powered by the new LS2 truck V-8.


As far as locating the engine for cheap I just spent alot of time searching here ......

Nice work, now fix those pictures!!!

[mewantkouki]

Holy unnecessary pull... Please tell me you bought the car like that and didn't do it to "fit" g35 wheels.

[StryfeS13]

^ Maybe the G35 wheels are temporary, ya know, just to drive the car..

I'm sure that is not his desired ride height.

[Gjohnson7]

Yeah, my G35 wheels are temporary until I can save up the cash for something much wider. The roll/pull was necessary to get the curve of the fender similar on both sides after all of the hammering and metal work that went into that fender. The stock fender shape was far from perfect. This is what I started with.

Oh, and this was me an a buddy test fitting some Mustang wheels to get an idea what 18 x 10's would look like. In the pic I'm running a spacer's in the front and rear because of the stock suspension. Also, front tires are 285's rears are 315's. Rear spacers are about 1 inch, front spacers are about 1 1/4 inch. My buddy is the one in the pic.

[Darkvillin]

could you please elaborate on what your mounts look like on the driver's side? is the driver's side exhaust very close to the header on that side? what harness and ecu did u end up using? how hard was it to switch over to the dbc instead of the dbw?

[Gjohnson7]

I'll have to check and see if I have any pics of the mounts, but yes they do run close to the manifolds on the driverside. When I had the exhaust made the shop had to trim the driverside mount to clear the piping.

I ended up using a truck harness and F-body PCM. The harness had to be modifed anyway so I went ahead and used what I had. I swapped out the blue and green PCM connectors for the Blue and Red ones used in on the F-body PCM as well as wired in F-body injector plugs.

Switching to DBC wasn't hard, it just required a diffrent tune and a change of equipment. LS1tech has multiple threads covering the conversion on their forums.

[Fahren]

nice build. bumped and subscribed for updates.

[Memberofthe600hpkaclub]

Uhh you got to be kidding...lol car has switched hands prob 3 times since and look at the last post date lol

[gdoubleos13]

Any update on the a/c?

[2muchboost]

Thread is like 3 yrs old...??? AC has already been worked out by company's like Sikky and a few have done a DYI setup.

[gdoubleos13]

I know I saw that when I posted late was hopin one of y'all knew something to help, been looking all on the forums trying to find info on it. I saw that A/V harness on sikky jus plug n play huh? Thanks man!
