Anyone tried a tailpipe turbo?

[Silent Runner]

Ok, I hate to admit it, but once in awhile I watch a weekend/morning show called "Power Block". In the last year they did a show upgrading two old pick-up trucks: an F-150 Lightning (351ci), and a 454 SS Chev. Now on the old (pre-supercharged) Lightning they added a turbo charger, way back in the exhaust system, and while it was not a big boosting monster(5psi), it added a great deal of performance. This is not the best way to turbo anything, it makes for longer air ducting, and slower spooling times, but it does simplify installation, and make it less costly to produce some decent power. (The 351 Ford smoked the 454SS in the perfomance dept.)

Anyone tried this set-up? I have a nice big empty spot on my 3VZ-FE Gen3 Camry, where my converter used to be that has plenty of room for a turbocharger.

Tony?

I would, if I wanted someone to get under my car to steal my turbo...

That's the Squires Turbo System (STS). I was thinking about making my own version using a CT26. As for the turbo lag, it shouldn't be that bad if the pipe from the turbo to the intake plenum matched the turbo's outlet diameter. That might give maybe 1 or 2 seconds for lag, which wouldn't be unreasonable considering the distance between the turbo and the intake plenum. I'd place it right where the muffler is, and make a shield out of the old muffler to hide/protect the turbo.

Can you tell I've seriously considered this? I even have the key parts to do it...N/A Supra green top injectors, turbo MAP sensor, and of course a CT26. I might still try this one day. For now, my '65 Mustang satisfies my power hunger.

Sounds reasonable....hell, I thought it was only found on Porsche 911 GT2s, then again, there isn't that much of a distance in that car so there is little lag for it.

I like this idea, because it simplifies alot of the plumbing associated with turbocharging (no custom headers), and moves alot of the hot stuff out from under the hood. uibalnme: Nice info/tips, on the appropriate parts list, I've seen a couple of Supra Turbos in the local yards.

I think you should just buy another car with more power.

BTW, I saw your car at Superstore again.

If you were talking to a normal, reasonable, car enthusiast, person... you would be absolutely right. But then I'm one of those silly people that like the idea of an old Camry going much quicker than it has any right to and putting looks of confusion on the faces of others.

-Besides, its getting a bit embarassing when I have to struggle to keep up with moms in minivans and SUV's with cartoons playing in the back.

[xpeed]

New minivans these day are quick. No need to be embarrassed by it.

[fenixus]

Silent Runner, do all moms in Canada street race with their minivans/suvs? :P heeeheee

I guess all that smart electronics and VVTi give a nice HP boost to almost all newer cars ... just wondering how long those cars last in the long run ... almost all electronics components are made in china nowadays

anyways, good luck with the project if you decide to pursue it. interesting topic, had no idea that car could have a turbo mounted on the exhaust side...

Oddly enough,... It does seem to me like alot of moms, at least locally, have a leadfoot on the gas pedal. That is until they get in front of you and pull out their i-phones. - (this is a young town and we have a huge local baby boom)

Anyway, I love everything about this car as I have built it. It is in every possible way (except one), absolutely a superior car to my last ride (the old 626 turbo). I still, after 3 years now suffer from occassional power withdrawal. Looking back, turbo boost is a bit like crystal meth. I loved how effortlessly the car accelerated at its stock 7.8psi setting, never strained or reving hard to go like, great... Then when I learned to turn it up to 12psi, same thing but getting a bit crazy. (could break its tires loose between 30 & 50mph). Then electronics upgrades and 16 psi, and the clutch wouldn't hold the power and I got the Camry.. and i gave up on that silly stuff and chilled to much more sophisticated, grown-up approach to daily driving. But boost is so addicting in a car, it lets you turn out huge amounts of power, even before you rev an engine to 4k, that you never really feel like your driving your car hard to put 200ft between you and regular driving traffic. Want to dust off the odd trail bur that seems to be trying to stick you in traffic up to 50mph? No problem, just skweeze another 1/4 inche of throttle and put him 30ft behind you in 2 seconds. That almost always seemed to put an end to the guy or girl that wanted to hang out door to door with you for the next 14 traffic lights. I still miss it, I still have withdrawal pangs as I have to rev my bigger V-6 to 4000rpm+ to hold on to local traffic, when a good step on the throttle and a shift under 4K, in my old 2.2L F2-T, Mazda would have put me 50ft out ahead and seeing clear road.

This car may well outlive alot of more modern machinery with crappy Chinese electronics, and other parts, but along the way I'm going to try and make her shine under my care in every possible way I can. Including maybe a couple of extra power mods. My old 89 Mazda made it (with me) to 380K, km., under 12psi boost, this car is made much better. I just want to wake it up a bit under the go pedal, maybe 250 whp will get the old feeling back.

[fenixus]

I believe you about the boost thing hehe. have seen a few boosted cars, never had a chance to drive one though.
always wanted to have a SC or Turbo only problem is the money needed to do it right ... and even more if things go wrong ... that I unfortunately cannot afford.

I think your 3vz-fe has lots of potential and could be much easier to release that hidden power on it than let's say compared to 1mz-fe. Just look what Tony the Tiger did to his camry

check toysrme power mods threads for this engine, there was a few tricks to make it run faster (not sure if longer though).

[slpr1mz]

kinda stoked some one has thought of this besides me keep us posted! lol

[camrypimp13]

thinking of doing a dual stacked remote mount turbo system on my 92 3vz-fe motor and to do it im gonna hide the turbos in the spare tire compartment and there should be no lag from the turbo if done properly one the car is running the turbo will spool up and keep pressure within the tubing and u put the waste gate in the front of the car so you dont have to worry about building the pressure up from the back of the car forward and im looking to stack the turbos so that i have boost power on all rpms from low to high, also you can do a dual exhaust on the 3vz-fe because the 02sensors are on the manifolds and just get 2 cats and weld the pipes together to make it fit down the exhaust channel down the car the good thing about remote mount turbo is you dont need a inter cooler because the airflow under the car with all of the tubing cools it for you just as well as a normal turbo with inter cooler but add one for even better cooling plus 440cc injectors for a 2jz motor retard the timing and a piggyback system to tune the computer also need to weld the flap inside the intake manifold open a high flow fuel pump and make sure you lower and add bigger breaks im looking to hook a laptop up in the computer to change the programming and have my car aroun 500hp up to around 800hp for the track if i want to take it im looking to drive it at 200+ mph!!!!!!!!!!!

1. You need to mount them exposed somewhat exposed to air to cool the center turbo housing.
2. You HAVE to run an intercooler. Exposed tubes won't cool properly.
3. You won't get over 500hp on 440cc injectors
4. You need to do some major research.

There are some serious downsides to STS style turbos on cars like ours. 1. The chassis and underbody isnt really good in terms of clearance especially if you wanna lower the car so tubing has to be small, strong and able to take a hit if you ever run anything over. 2. Running cooler lines will be a PITA (which will be important because it will have to spin faster to create the same boost with all the extra tubing). 3. You still have to do the really expensive stuff like tuning and supporting mods. 4. Most guys running STS style systems get them as a kit so all hardware is made pretty vehicle specific. It would ALL be custom in your case.

My biggest concern with this would be the clearance and cost efectiveness; would it really save THAT much to do it?
