Remote-mount Turbo?

[Gothmog3VZ]

posted this question originally in dcninja's thread, but didn't want to end up hijacking it :P

I asked about the merits of a STS turbo system (www.ststurbo.com) relative to other forced-induction systems, my concerns being space under the hood of a gen3 V6, and budget.


I was thinking of boosting around 8-10 psi (so, more like 6-8 with the ~2 psi power loss)
of course, that would require an investment in some new pistons, rods, valves & springs, and gaskets.
and I'm planning on getting a methanol-injection system set up once I find the spare time/funds (college starts monday, need to buy new science books -_-)
exhaust system is being fully replaced sometime in the next 2 months, hopefully sooner, due to rotted flanges, flex-pipe, and a hideous noise when I lean on the gas, which means that section should be able to handle it.

now, TN, explain to me why/whynot to get this system (pros, cons, issues, and other related info)

one of the biggest drawbacks is of course the loss in pressure and lag with this system. another is the distance youll have to run everything like oil lines and tubing from the turbo. i think the biggest roadblock is still the normal things that prevent most of us from FI, money, parts and prep. in the long run it may only be a little easier, cost wise it will likely be about the same when ya factor in the entra money for tubing, oil lines and an oil pump that can move it there. one advantage is that it will keep the engine bay cooler.

but both setups would work. toysrme had a remote mount like setup and it did ok. on the other hand more have done a traditional engine bay system and also been successfull. samarai912, tonythetiger, and others. once you remove the battery theres enough room to work with.

but i am by no means an expert, a little research should give ya all ya need to know about both.

[Gothmog3VZ]

hm, okay
did the math, with everything, it should come to ~$2500 (not counting the pistons and whatnot, but that cost would be added to any FI I might do)

How much did Tonythetiger and Samarai912 spend on their systems?

also, where did they relocate the battery? trunk? and how long/how much labour was involved in their projects?

keeping the engine bay cool was one of the things that drew me to it; apparently, it doesn't need a turbo-timer either...

Did Toysrme do any dyno testing with that setup? I'll send him a PM, but I'd be interested in seeing what figures a 3VZ could put down with it.

[Toysrme]

tony spent thousands.
if you have a welder friend you can get it done for under $1500, but you need to be dedicated and it needs to be YOUR CAR. NOT YOUR PARENTS CAR.


move the battery, move the cruise controll. there's plenty of room for an up pipe, and not alot for a down pipe. if you just can't get your down pipe to fit around your transmission case. If you move things around on your firewall and things like your EGR and speed sensative power steering vac lines you can put your down pipe like Tony has his.

OR you can cut out the battery tray, cut a hole in the fender & drop the downpipe out the fender well.

the remote mount turbo has always been something i was interested in... i'd love to try it on just any old piece of crap car... just to try it...

yeah youll have to run oil lines and a charge pipe back to the intake... but.. with the right sized exhaust system, designed with better flow in mind, i wouldnt think you'd get too much lag... just use a small to medium turbo...

the beauty of it though is your air cools under the car when you are driving...if you put some like heat sink type fins on the piping too that might help... but with this, you dont need an intercooler for most early project situations... lowish boost...

with a v6, you could run twins pretty easily.. the problem is space though...

[Toysrme]

without moving the firewall or subframe & radiator/fan you don't have room to mount a baby GT12 or ihi-rhb5 class turbo.

for a remote A/T you could get away with a t3 60/super 60 turbo. use a rare .36 turbine entry. that would probably go pretty good in the upper 200's.

sometime latr this year im planning on dropping a new engine+A/T in mine. front bank will run a t3 .48(twin entry) / t4 57 or 60. will likely be resonated and open dumped immediately under the turbo.

if it doesn't spool well ill fab up a quick spool valve out of an old wastegate actuater in one half of the inlet al-la chronic style










not sure yet. civic needs rings & a clutch, perfect time to turbo it, lexus needs a new A/T...

[Gothmog3VZ]

lol it is my car

yeh, that's the other thing I liked, that an intercooler is optional on it
and it seems like it would be a lot simpler to install, relative to moving/removing various bits of hardware under the hood (although I'm probably going to ditch the power-steering, it's too strong imo)

however, like mentioned earlier, there is more pressure-loss on a remote-mount than conventional. in any case, I have a bit of time to deliberate this (I'll probably start the work mid-october, finances providing)

interesting thing though, mounting a twin-turbo system would seem far simpler on a remote-mount...

Not only did TonyTheTiger spent thousands, he spent alot of time and energy into his Camry. He even rebuilt the freaking engine I think.

The STS TT system is pretty well known for Corvettes. Its main advantage is that it allows the use of bigger turbos than other kits since packaging under the hood of vettes is tight. It suffers from increased lag due to all that piping, but the lag is barely noticeable since the turbos are still relatively small for the large displacement engine.

I imagine the STS on a dinky little 4-cyl would be pretty laggy.

We all start with a couple of grand, but then it always ends up being 10x the amount, especially when the Camry is a 1994 and I had it since it was brand new. You lose track of what you spend in the course of 10+ years... lol But the Camry gets about $2500-3500 each year for mods.

Remote mounted turbos are a waste of time... The reason they work for Vettes/V8's is due to grossly undersizing the turbo and turbine housing to battle against the huge flow/heat/pressure loss with the turbo mounted 10-12 ft away. Imagine a T04E/T4 0.69 A/R turbo, this would be a turbo I'd slap in my 1.8L Honda, not a LS1 V8. No doubt the STS kits would spool decently on a V8, but you can never do the same on a modern import engine that is sized way different in terms of engine displacement vs turbo capacity.

STS tried to market their kits in the Honda crowd... Sadly, it was nothing but fail.

[Toysrme]

the major difference being that you can have atleast partial justification on ALL your work on ALL your cars and being good for your biz.

Have you a 10' sign saying 500whp parking ONLY and youd get some attention at the shop.

3VZ

still not massive though

So, my best bet pretty much would be to shift around/ditch some under-hood components to make room for a conventional setup?

And 567whp?!? you must have some insane 1/4-mile times, Tony
eh, I hope to eventually maybe cross the 400whp barrier, but that's going to be a few years down the line...
