I'm going to be ordering a turbo blanket for the car in the next couple weeks here. Every other exhaust piece is going to be wrapped as well. As long as the coolant temps stay down, and nothing melts then I'll just roll with what I've got. I am also going to be moving the fan to the front side of the radiator and use it as a pusher. (JUST looked up the fan part number and found out I've been using a pusher fan as a puller.
) If heat is still an issue then I'll be looking into a new radiator or something to keep things under control. There are only 2, E85 stations here in San Diego, and both are 20+ mile drives from my house. My intentions with the car is to make it a pump gas car, so I'll be sticking with the 91* Eventually I'm going to swap the Heads out for the 317 heads to lower the compression like Cobrakilla suggested. -
Well, last night I got my pan pulled off. Brought it into work today and drilled me a nice big hole. Brought it over to a friends house who could weld me a bung on it after work, came home and installed the damn thing! pics!
And for the pics you've all been waiting for! Its not bolted down or anything, nor is the manifold done, but this is where the turbo will be sitting for the most part.
Enjoy!

Thanks guys, The cross over pipes are 2.5" 304 stainless. Tonight after work I pulled the pan and will be getting the oil return bung welded on tomorrow. Hopefully getting the pan installed back on the car tomorrow as well.

Most of my buddies said the same stuff. "That turbo is going to fall apart!" ect ect ect... I've heard it all. "Those compressor blades are glued on." Hah. Anyways... So heres some pics of what all I did. For starters, Heres a bunch of intercooler pics. Had to of been the easiest, fastest, and smoothest intercooler install I have ever done in my life.
Heres the "modified" manifolds installed. Compared to the original ones I had, there is a bit more room between runners to get some spark plug wires on there.
I spent the rest of the weekend working on the support bracket(hideous, I know) , collector, and middle section of the manifold.
Oh yaaa, I forgot to mention. All the welding, and fab work is done by yours truly. And the welder I am currently using is a 200$ Harbor Freight, scratch-to-start tig. Works bitchin!
-
Does that turbo use a T6 flange? Also, does it have a 5" v-band output? I can see it is v-band, but just wondering the size. My turbo went to crap on me and to swap a new one easily it needs a T6 flange and 5" v-band.
BTW, those homemade turbo manifolds look really good. Like Scottie said, spark plug wire clearance may be the only issue.
The turbine is a T4 twin scroll flange. The outlet ID is 3.5" and O.D. (from outside of the Vband thing) is 4". I haven't really seen any china turbo's much bigger then this one. What are you running a T6 turbine flanged, turbo on? Pics!!!
Thanks for the compliment on the manifolds! I actually spent a bit of time on them yesterday cutting the flanges off and welding in 3/4" tubing to space it out. Gave me a lot more clearance and should work out after all. I dare you to go to Freshalloy and post your first post over there
What is freshalloy? Which 60mm wastegate are you running? I've never actually heard of anyone having problems with them, yet. Except for the plunger not sealing 100% They are a little bit more cheesy then a real tial, but for the price you cannot beat it. I've watched the video in your sig. many times already. I freakin love it! Car looks good man!
So I got a bit more work done to the car this weekend. I got my brace all finished. Its pretty beefy, but very ugly. As long as it works, right? Got the intercooler all mounted up. Also got the manifolds bolted into the motor. I finished up my collector, and got it connected to the driver side manifold. I'll post pics later. I am POOPED! Time for some Taco Bell.
-
Oh ya! I'm getting the rod bolts too while I've got the pan off for "bung welding" Good call. Thats pretty bad ass about those heads. but after all, this is all going in a Z. And anything upward of 450 at the wheels should be enough to satisfy anyones needs. I sure hope I'm satisfied after the turbo swap, cars are an expensive hobby.
-
The lines in the turbine housing just look like casting marks, not a big deal.
Cobrakilla, Those are some excellent suggestions!!! Thanks! I've already looked into getting some 317's from LS1 tech. They seem to go pretty cheap on there and are abundant. And thanks for the info on the stock plug wires.
You're suggestions and help are much appreciated, so feel free to add anything, anytime. -
Nice work!
If you are using a high-mounted alternator and no a/c, flipped truck manifolds would have worked. However, I understand having the skill to roll your own and do it at a reasonable price. Only concern, a minor one, is if you have enough room in those manifolds for the plug wires.
I am wrapping up a turbo LM4 (alum 5.3L) for a buddy and the engine has F-body accessories and the owner wanted the a/c. I ended up using a modded pass-side 6.0L manifold on the drivers-side and had a simple log manifold made for the pass-side to clear the a/c compressor. Would love to have put the turbo on the pass-side, but with the a/c compressor, water pump inlet, heater outlets, turbo, air filter and WG all crammed in that corner, I did it the way you see it. Using the same I/C.
This is for an FC RX7 vert with a T56. The engine has 317 heads, Z06 cam and "yellow" springs and ARP rod bolts, MPT T70/p-trim/.96 and Speeder will be doing a megasquirt to use the coil-near-plugs. Will be a mild street car, no drag racing.
Ya, those truck manifolds do look pretty nice! And the spark plug wire fitment did cross my mind, I was considering getting something like this:
Would possibly be small enough on the spark plug end to make it doable. And plan B was going to be getting "make your own" wire kit and run it all behind the manifolds and plug 'em in from under. Everything will be heat wrapped including the plug wires them selves. I guess I'll just have to cross that bridge when I get there. So how much longer till you get the car running? As for the exact pieces I used... the 90* peice 45735K215 The T's 45735K255 and then the reducers on the ends of the manifolds I'm pretty sure I used these 45735K425 Once again these are all off of the site I provided earlier, "McMasterCar.com"
Rustorbust, As long as its dry out then I'll be working on it Sunday - Monday. This is also considering that my 2.5" 304 stainless U-bends / 45* bends come in on Friday.

Loving what your doing so far, that motor is going to be a monster. Where did you get the pipe sections for your manifold? That is a trick way of doing it for cheap, and should work as well as any factory manifolds out there.
Im curious to see how the car preforms and especially the turbo, might have one in my future if it works well. I didnt have a good experience with my name brand turbo on my L28, might as well have been "china junk"
Keep the pictures coming!
Thanks dude! I picked up the pieces from McMaster.com Its such a great site. Once you're in the site, in the search window on the left punch in, "stainless steel butt-weld pipe fittings" and it lets you choose from Elbows, Caps, T's, Couplings and Stub ends. You can get pieces in different sizes, different metals, different wall thickness, ect... I've built an equal length manifold for my old turbo Colt using pieces from that site in the past and its still holding up over a year later. More pics to come this weekend!
-
That setup should work very nicely...
what are you going to use for engine management, injectors, fuel pressure regulator, etc?
I'm getting some 60# injectors and am going to be running some duel Walbro 255's. For the time being, I'm gonna run the stock Vette regulator / filter. Eventually I'm going to swap to custom fuel rails with a boost (whatever you call it) regulator. For management I'm using HP tuners, Starting off with blow through MAF, and will eventually swap to 2 bar Speed Density.
-
What heads are you using with your set up?
I've got some 243's off of an 02 ZO6. Suppose to bump compression to 10.4:1. With that said, I'm going to be running pretty low boost.
Hey I read your thread the other day about running 7.1 down at the stadium congrats, that is moving for that setup. Kinda funny though cause when I read aboutyour last runs at the stadium I was going to comment saying how badass your car would be with a single turbo setup. I actually got my z all tore apart in my garage right now doing a single blowthrough setup with an older airesearch t4. Where exactly do you live at in san diego, I'd like to meet up with you sometime and check out your stuff in person. And oh yea, your looking to gain a 100 hp hahaha man I think you should be able to tack on at least another 200 to 250 with low boost and a.safe tune.James
Woah!! I had no idea that there was / would be another turbo V8 Z in San Diego, thats awesome! I'm right off Mira Mar rd. in Scripps Ranch. Got some link or pics to your project? This rain is killin me! I'm hoping it will let up before this weekend so I can knock out a bunch of work. I figure if I run the boost low enough that I can keep the power maintainable. Or at least I hope so! (crosses fingers)

Joker, Thanks bro! I Just decided to build my own so I know it's going to fit how I want it to. It also makes me feel pretty good about myself when someone asks. Where did you buy the manifolds from? and I can say.. "Ya, I built those myself."
Reef, China / EBay turbos are just non name brand stuff that basically came from China mass produced and is sold for dirty cheap. This turbo IS huge, pictures don't do justice. I'll probably make more then 100 hp for sure, But my goal is to get in the 500's, and keep it in there. I don't want the car to get out of control. Well, not too out of control

Hey guys, So I recently decided to go with a turbo instead of going with the Heads / Cam / Intake / TB package, or NOS route. I'm going to be building my own manifolds, and piping, and everything else. I've pretty much got everything I need, just need to get crackin on it when time lets me. I'll be updating with pics of everything along the way, thought I would share. My goal is to gain at least another 100hp, and spend as little money as possible. Here's what I've got so far.
For manifolds I've decided to build some Log manifolds. Due to basic design, cost of materials, and simplicity I was able to finish both manifolds for roughly 200$ They should do the trick. Took a couple hours to build both.
I've already picked up a wastegate, ( same wastegate that dustin280zx is using in the Gen 1 / 2 V8 threads. ) And for Blow off valves I'm going to be using 2 factory blow off valves from an early 90's Mitsubishi Eclipse.
I ordered all my Oil line fittings from Summit and picked up a few from Home Depot, Never knew how cheap buying AN fittings could be. I was able to find a few of these fittings for less then 5$ pretty sweet. I also got an Ebay intercooler. Which should fit, and perform well.
And for the best part of it all, the turbo... I ordered a GT45 Ebay turbo. Knock it all you want, but the price was soo cheap that I figured it was worth a shot! After all, its got a divided T4 flange so if it ends up breaking, I have plenty of options for a replacement. price was 330$ shipped. The shaft spins perfectly fine, and continues to spin when you let go. Zero in / out shaft play. Normal, minimal side / side play. I can't wait to run this thing!
So thats all I've got for now as far as pics go. My Z is up on jack stands, all the N/A stuff removed just waiting for this weekend. Like I said, I'll be updating with pics and info along the way. Enjoy!

i was just wondering if the ls1 and the ls3 are the same, like do the headers from a ls1 fit a ls3? also has anyone used the JCI kit on a Z with a LS3? does anyone know if this kit will work in a z with a LS3? anyinfo will help. thanks
Well, anyone here can correct me if I am wrong... but the LS1 is a Gen3 engine, and the LS3 is a Gen4, But the the LS2 is also a Gen4 and since the JCI mount kit works for the LS2, then it should work for the LS3. Also, the header flanges are the same between the LS1,6,2,3,7. LQ9, and 4. GM was cool like that.

Can I ask what RPM you are launching at? Dump or feathering it out of the hole?
For Daily driving how is the cam?
I was around 3500 - 3800 rpm, basically just dumped the clutch and held on with my foot to the floor. Seemed to do the trick.
My Cam is pretty sweet on the street, I have no complaints at all. It makes 300ft. lbs at the wheels at 2500 rpm. So unless you try and pass something while you're idling, its pretty good.
-
Holy cow! Thats one insane deal!! You're gonna one hell of a beast on your hands.
-
yes, drivers side mount. You're not alone my friend. luckily when you mash on the gas, the motor torque's in the rotation that pulls the alternator up and away from the mount
-
My Alternator was damn close when I first got everything installed into the car. Thanks for the reminder to go make sure its not going to make contact! I think I slipped some rubber in there between the Hot post on the side of the alternator just in case it decided to short out on me. I've been alright so far.
-
By all means look through whatever I've got, no biggie.
That mount is basically my finished product, minus two holes. It turned out pretty good and seems to be doing the trick just fine. I inspected it after the night of beating the ♥♥♥♥ out of it, and it seems to be holding up quite well. Not bending at all. Bigdeez... Get some ET drag slicks and get your car back on the track!! With your power, you should be trapping 100mph in the 1/8th, and pulling some 10 sec. E/T's.
-
Very nice times. I really like the pictures too, great vivid colours.
stock 243's and a decent cam have done you well. Are you running the LS6 intake or a FAST one? Stock TB? Lastly any idea on what the weight of the car is?
Hey thanks! I'm running the LS6 intake manifold, Fasts are freaking expensive!! The throttle body is stock as well. I'm really not sure what the car weighs, if I had to guess I would say just under 2500lbs.
-
Thanks for the compliments guys! I'm running a T56 in the car, and the slicks are 26 x 8.5 x 15, mounted on stock Z wheels obviously. The car has a VLSD Q45 R200. Never had any problems with it at all. The heads are stock un ported C5 Zo6 heads. The "243 castings" I'll tell my bud you guys like his pics, that'll make him happy.
-
I've got no experience with EFIlive either, but I have been using HPtuners for a while now. Its very hard to get use to, but once you've got the hang of it its pretty user friendly and gives you a ton of adjustability. Good luck with the EFI live!

So this past weekend I got my car out there on the track. Ended up doing much better then I was expecting. Last outing I made to the track I did 8.0@94 with a 2.0 60 ft. Well... new heads, tires and tuning got me a 7.1@98.4 with a 1.5 60 ft. best mph of the night was 99.7. Unfortunately their's no 1/4 mile tracks within 100miles. So I have to stick with the 1/8th mile. I got 9 passes in, did not break anything the entire night. Drove it to and from. Not to mention had a great time!
heres a vid of my last few runs:
And a few pics that my buddy took.

well since i could have all the tt swap parts for under 5k from z1 id say deff under that. hell i was hoping to spend under 1k for the tranny and close to no labor until the wiring... but idk if thats gonna happen. the main reason i wanted this was to save money. but after looking arund im not sure if ill be able to keep my interior shape after grinding for the tranny... unless i can make a z tranny possible.. i would spend money to get a built one from z1 if i could connect the two..
i heard somewhere that its impossible... what all does it take to match a tranny to a motor?
Save yourself the trouble and just buy a T56, and make it fit. T56's are awesome, insanely strong, shift when you want 'em to, transmissions. I have seen them for sale on LS1 tech for average price of 1,000$ - 1,200$ for a good used one.
) If heat is still an issue then I'll be looking into a new radiator or something to keep things under control. There are only 2, E85 stations here in San Diego, and both are 20+ mile drives from my house. My intentions with the car is to make it a pump gas car, so I'll be sticking with the 91* Eventually I'm going to swap the Heads out for the 317 heads to lower the compression like Cobrakilla suggested.

Thanks! and thanks for the advice, I've had many a modified turbo car on the past. So I know what all the advantages / disadvantages are. As said earlier, I'm going to be running HP tuners to tune everything. I've seen a lot of turbo LS that do VERY well and make big power numbers. And I've seen others that just suck and make less power then I made NA. We'll see!
