That Mocal pump is what I had ordered from Racerpartswholesale, and had ready to go for my rear mount silverado project that never got off the ground before I sold the truck Looked like a very nice pump, and racerpartswholesale seemed like a very good vendor. I sold the turbo, the pump, aluminum lines, boost gauge and pillar pod to a guy who was going to do the same thing to a 97 K2500 silverado. That was almost two years ago and he still hasn't done anything with it either

You know, I’ll buy that this works when packaging is tight, that it’s better than no turbo in that kind of setup, but for the life of me I can’t figure out why someone would waste their time with this in something like a full size chevy truck, where you have enough spare room under the hood to mount like 16 turbos and still have room for plumbing no matter how retarded the routing you use is.

Roc87

Trying to help out here, was going to remote mount it just because it's not the normal thing to do, kind of like having a t/a with crossfire injection

New ideas are always good, but as 83 Crossfire TA said....it isn't worth doing a remote mount in a truck. The gains are better doing an engine mount. Of course, a remote mount done properly is better than no turbo. In the 80's truck I have there is enough room to mount two 1200+ HP turbos. Besides, a truck is usually a winter vehicle and the salt is major wear & tear on a turbo.

Roc87

Hmm, I guess you guys are right. I'll have to let STS know their kits for the Tahoe/Yukons/Escalades, are all wrong, and they better recall the ones they've sold, the rust might make them fall off.

This is a guy I met on TurboBuick.com, who is running an STS kit. This is a FULL SIZE 4x4 Chevy, with out posi. AND YES, that's a 12.95, with a 5.3!

Crossfire TA,

Wow! I'm glad that someone here has a balanced perspective on design principals!!!! This has been hashed out over, and over and over and over and over.........And it's still the same BS arguments. 'Mine runs fine', 'my 5000# truck runs in the 12's', 'STS's PR people say that heat doesn't really drive the turbo' BLAH, BLAH, BLAH. Let's face it kids, a turbine is driven by expanding exhaust gasses. Period! Go to an air force base if you don't believe me and ask one of the jet mech's. That expansion is because the gas is hotter than the outside world.

I'm not trying to bash any rear mount owners, IF they HAVE TO mount it there, but otherwise it has little merit. Why do you think that the kit makers have such a small turbine side on those designs?! Again, if the performance is adequate for you go for it. But don't bash 87 crossfire TA, his comments are valid.

Although....Well I hate to admit it, Roc87, but your shot about the crossfire injection was a nice shot, a real zinger!

sleepybu

other then the sts whats all done to that truck?

Roc87

In that video, I think it was stock aside from the pcm tune, STS kit, methanol injection and a 3k stall. Since then he's swapped out the turbo that came with the kit for a GT67, added a front mount intercooler, 226cam and 43lb injectors, and a 6.0 instead of the 5.3 which has netted him a 12.33 at 110mph, weighing in at 5250lbs. He said the GT67 has affected the drivability of the truck, as far as lag (that turbine side of the compressor deal). He's now tuned for 13psi of boost rather than 5, and says until the boost comes in above 5, it's like towing a 5th wheel.

Well, except that WBO2's specifically don't like pressure or excessive heat...

browncamaroz28

iTrader: (1)

i'm pretty sure thats not true, i have to agree with 83 Crossfire TA... wideband O2 sensors are not designed to be operated under that pressure (pre-turbo)... it needs to go after the turbo, right after the turbo would be best... units like the lc-1 have a good heating system so it doesn't matter that it wouldn't be right after the engine... the sensor will be accurate....

firstfirebird

iTrader: (3)

I've had nothing but problems with my LC-1, unsure if it is the sensor or controller. I have checked the wiring and all the connections are soldered and heat-shrinked. Haven't tested the sensor yet, but might just give up on it and try the PLX. For a temporary fix, I put a bung just after the collector for the stock NBo2 (befor the turbo). Wondering if it could be from a rich mixture?(The sensor is about 2' after the turbo in the down pipe).

junkcltr

iTrader: (1)

After building a DIY-WBO2 and looking at the design, I quickly saw that the packaging alone for the LC-1 controller is fragile both from an electrical and mechanical point of view.

I have heard that the LC-1 can't take over-voltage & under-voltage from starting a car or they break electrically sometimes (DIY PROM board and Innov. directions/FAQs). They sometimes have solder failures internally from vibration. Overall, I wouldn't buy one just for the simple fact that electrically they seem like junk. Although, their algorithm seems half decent......the electronics and mechanical design is not that good.

In terms of pre or post turbo installation, pressure affects a WBO2 reading. That is why the LC-1 should be calibrated at first according to the instructions for elevation (pressure) reasons. Now if the LC-1 folks do a real time (quite fast) update then the software could adjust for the increased turbo exh. pressure before the turbo. Highly unlikely that they do it that fast so a safe bet is always to put it after the turbo where the exh. backpressure is lower than before the turbo and where it remains more constant. The update is probably done more slowly because not may go from sea level to 5500' above in msecs. That is how fast the pressure before the turbo changes from no-boost to boost.

Yes, you can put it pre-turbo but you better know how the WBO2 controller algorithm works for the calibration.

shocker89bird

Just noticed this thread is several years old now. Thought that was cool. Nice seeing any type of custom fabrication on gm vehicles.

83 Crossfire TA

iTrader: (2)

the innovate documentation specifies that pressure will damage the O2 sensor, as well as excessive temperatures, both of which a standard O2 would work fine with.

as far a the previous truck arguments... just because you can make something work doesn't make it a good way to do it.

What is your engine's static compresion ration?


I have 2.0 16V (GM C20XE) 167HP/205Nm (remaped), with 86x86mm pistons, 10.5:1 static compresion ratio, fully open exhaust without cat, with Wizards of NOS (wet system, direct port, progresion controller, 70HP shoot).

Without NOS I have about low 15's on 1/4 mile. On NOS I have high 13's...

I'm tired of filling botles, so I would like to do a turbo. Remote turbo idea seems great to me. I was thinking the same 7psi boost with 14psi overboost on button.
What turbo should I use? What about remaping and firing times? How did you manage to avoid knocking?

What do you think about power steering oil pump for turbo? I was thinking about closed oil system just for turbo. With little oil sump, oil cooler and electrical power steering oil pump to circulate oil through it.

mr_g

You could use electrical power steering pump that opel zaphira and other cars has (on junkyard). I use one for my power steering instead of mechanical belt driven pump.

It has oil pan on it self. And all you need is litle oil cooler and you have divorced system for litle $...

I can't really remember what he ran in the camaro. actually his brother was running the camaro and he was in the cavalier that day. I think that I do remember the camaro being slightly slower though but then again this was his brother driving.

Been looking at doing this to my 95 saturn for a while now & just found this site. Imagine a 1200# car with 109 hp na then turbo it.

Your car isn't 1200lbs, try more like 2400lbs.

Not that a good turbo setup won't improve your power by leaps and bounds though. This thread prooves that theory welll enough.

My bad I misread the door sticker. Its actually 3245 lbs.
Thanks for making me take another look.

Thanks- Brandon

oakley88

i wanna do this on my 94 pathfinder with a vg30e engine. would it be possible to put the turbo after the y pipe and then run the charge pipe back to my intake. i am getting headers and a y pipe so i figured it i already was messing with the exhaust that i might try putting the turbo here. any ideas

wny82zproject

maybe a stupid question but i know very little about turbo systems. i was looking at the sts turbo systems, and they seem like they work pretty well (not much lag etc.) but i am building a mild 350 (aprox. 400 hp/tq, 9.5 comp.) and want to stay carburated. how difficult would it be to use a turbo system like this on a carberated engine. would i have to build a custom flange or something to direct the air from the turbo right into the carb?

ClgCustom

Its funny i found this page, alot of my questions where answered and alot of my theories were thought of here as well, I have a 97civic D-16y8, 1.6liter with v-tec, it makes 130hp factory, right now i have a 4-2-1 header with 2in collector into 2in cat and 2in all the way down the car to fart can. Denso Iridium plugs, high energy coil, Nology hotwire capacitor wires, P N P intake mani, AFPR set at 40 with vacume, very tight valve lash, slightly tighter than factory. For the turbo setup i have a perfect low milage SRT 4 turbo, exhaust snail cut from manifold and ported and polished in and outlets, same with compressor housing, oil filters sandwhich for oil supply with steel braid line to solid brake line back to steel braid to turbo, out of turbo to Tilton 40-524 oil pump, back to valve cover. 12/1 Fmu and check vavle for Map, but will prob discard those two for ecm and injectors and pull up to get tuned.

Wow. I visit this forum for the first time in like 2 years and this this thread is still at the top!

Just some quick updates on this car. I just finished running it on HOT ROD Drag Week 2008. It ran great but developed a some clutch slip issues. I lost the Quickest 6 Cylinder plaque by 0.018 seconds to a GN (thanks to the clutch- the car had a lot more in it I'm sure, hope to prove it soon). Oh well, it was a ton of fun. Fastest pass to date was on day 1 of drag week, a 12.41 at 112.8 (clutch slipping in 3rd and 4th), highest trap speed was a 12.51 at 116mph. This was at 13psi on a $500 junk yard mini van motor! Totally stock 3400 V6. Stock driveline too, except for an LSD insert in the transaxle.

It now has an intercooler, and is controlled with an MS2 and 42# injectors. The turbo hits hard enough to light off the street tires in 3rd gear at 50+mph. We got 27.5MPG at 75mph with the A/C cranked (it was near a 100 degrees most of drag week!).

Here is a video link to some passes I made at the Steele, AL race. The first run was good, but not my best. The second run you can easily hear that the clutch is slipping.

that looks excellent... thanks for puttin up the newer pics. mid 12's in a cavalier is definitely giving credibility to the rear turbo system.

i know this might be a dumb question, but when you get an inspection do they give u trouble for not having a true muffler?

84z28350

haha, that turbo cavy is wicked!!

Just wondering if anyone here has come across any SMALL 12v oil pumps. Im trying to find something different to use on my sled. I am currently running a tiny greylor pump, but the 12v ones will burn up fairly fast and the 24v (which im using now) runs pretty slow, just enough flow and pressure to get the job done...

Space is pretty limited so im not sure if i can get anything else to work...

mikabrandl

woaw, i cant believer i catually read through most of 9 page of this thread... good info tho i always thought rear mount could be cool but is there any way to get the oil to return without having to add a pump ?

j88l98irocz

iTrader: (4)

No, obviously It can't be gravity fed so the oil will just build up in the line. You have to use some sort of pump for a rear mount turbo. Installing an oil pump like the mocal 12v op is really not difficult at all

89JYturbo

This car is now going in the 11's. Best pass to date was 11.9 at 119mph. Its been in the 11's the last three times I had it to the track.

Using a two step set to 3100rpm I leave with about 4psi of boost. Low 1.8 60's.

Still running a $500 junkyard motor too.

That's great to hear kenton, I still have your old 2.8L turbo and plan on installing it after the paint is done on my car.

Hello John. Were you the one with the white IROC with ZR1 wheels? I don't remember where my car was at that point, but if it was painted orange when you seen it, it is in the exact same shape right now. Its really not that fast. I 've been far more impressed with the Z24, but thats because I have learned a lot since I built the IROC. I evaluate plans nearly every day for what I want to do to my TT IROC. I'm still not sure what I want to do with it, but I'm leaning towards selling my current engine and turbo system and starting over with a 6.0L truck engine. I want it to be much faster, but being I run my own auto repair shop with one employee and we just bought new shop (working on zoning to see if we can actually move in there!), I have very limited time for a big project like that. Not to mention limited funds!

I also don't have internet access at home, so after a long day of work I don't care to spend too much time on the office computer to chat on forums. That in no way means I'm not interested in the car scene anymore.

Where is Richland Town PA? My employee lives in the town of Richland in Lebanon county. Are we talking about the same place? if so, its only 15 minutes from my home and shop.

After reading this I am very impressed with what you have done with your car. So, props for that. I was wanting to mimic this setup on my 89 Trans Am. I have very little knowledge on turbos, but the work and fitting would be no problem. The biggest hurtle I have is the sizing of a turbo. Could I use a T35 off a Z, or would I need something different all together. I have a stock 350, I mostly want to improve the top end of the car, but a little down low never hurt. lol.

Wildwood carshow/ cruise kinda sux now with the cops hammering everyone with fines for burnouts.(kinda ruined the fun) You're car was painted orange that Iroc is beautiful. 6.0 swap would be great, idk if you read the thread on my tt Iroc build (check out my new power adder) but long story short I parted the car out and sold the roller. I now have a 02 Camaro ss with a custom pt88 turbo kit, forged 6.0 ect, through a th400 and a 9in it still put down 839rwhp and pulls on 1000 street bikes no problem.

Still running it. Its gone 11.87 at 121.5mph in the quarter and put 383hp and 433lb/ft of torque to the wheels at 19psi of boost (pump gas with water injection, stock everything in the engine!).

I'm only a 2nd gen. '02 S-10 Crewcab but, it's a 4.3 Vortec, 4L60E, 4x4. I'm in the process of sitting it down 4" front and rear with springs rear and coilovers front. I'll probably go with 8 x 15 alloy wheels 4 1/2" back spaced. Once the stance is right I will go to RMT but I'm thinking two stage dual turbos in the bed. Divorced oil system and water IC. Any thoughts ?

alex91z28

what happen with the cav and the tt camaro?,

89JYturbo

I still have them both. I drive the Z24 on weekends, it still puts a smile on my face every time I drive it. The power is so violent, its hard to believe the drivetrain has held up all this time!

I never got the TT IROC built to my liking. But I can't part with it, just need some time to re-do it right!

89JYturbo

The purpose of the remote mount is to simplify. You are overthinking it. You should ride in my Z24, you will see that the lag time is a non issue. My 3.4 V6 has a torque peak at only 4100RPM, which is where the boost peaks at 19psi. You'll probably want to change the fuel injection system on your Vortec 4.3. I don't think there are upgraded injectors available for the original intake.
