I have been typing to Revhard performance the last couple of weeks and they have a turbo fitted on a scion right now that produces 65-70hp! They have to do a little more testing but 65-70hp! ITS WORTH WHAT IT COSTS! You should be able to pass emissions though.

wow....got any pics of the turbo kit? dyno???
price???

come on, tell us more...

Warranty? What warranty??? We want details!

yah...you can't jus leave us hanging with no info...thats hella mean :?

Reality check time.

Enough boost to add 65HP to a 105HP normally asperated engine will likely result in detonation. The CR is already high (~10:1), and putting 7+ PSI of boost into the manifold will result in an effective CR of 15:1. You had better like running race gas or methanol for fuel, as these are the only ones that will resist detonation at this CR.

Passing emissions is easy to determine. If this system has CARB approval, you pass. If it doesn't, you don't. Care to wager if this outfit has spent the thousands of dollars needed to obtain CARB approval?

Skeptical? Yes. If it sounds too good to be true it probably isn't true.

10:1 isnt considered high comp. I know a lot of sr20 owners taht auto X and run high comp pistons and high boost for responsiveness...i must say its nice....but i do agree 65 to 105 hp is iffy. 65 hp is feasible but almost borderline

I would have to say that 140-150 boosted hp SHOULD be the max, to prevent detonation...

I think the engine itself can handle 150 hp with the stock internals..however, I would start worrying about the tranny...expecially the autos....they arent especially robust.

time will only tell what horsepower the engine is capable of. getting a carb number is hard to do and it will cost some money.

The only reason I say this....I have heard stories of bB owners popping the automatic transmission with the power enterprise supercharger pushing about 150 hp.

Agreed... BUT EIP tuning has their turbo echo project running.. I ____ you not. 15 PSI on stock internals. Now that obviously is related to the standalone and ____ load of tuning.. and not to mention they arent using the ____ water gasoline we get in CA, but yes it is possble to push more than 7+ psi on stock internals. I just don't think our pockets are deep enough for that. Any more info on the kit?? I haven't heard super great things about revhard...I just remember I spanked a GSR that had their kit and was pushing 8 psi, when I was still on my stock DSM turbo.

I also wanted to add that 65hp is flywheel HP. there is no way in hell they are going to get that much out..


Anyways just got off the phone with rev hard and here's the story...

They are going to be using a t-28 turbo. Which flows about as much as a small 16g, but spools just a tad faster. Right now they are working fuel managment. They are thinking of just adding an additional injector and some sort of AFC or some other kinda piggy back computer. There are no power estimates as of yet. The first dyno run was yesterday for a baseline. That means the scion was stock. They are still deciding on what they are going to include in the kit, but it seems like they are going to include everything.. FMIC, couplings, pipes, turbo w/ wastegate BOV, fuel management........ Here's the sad part.. estimated retail price.. $3500-$4000.. OUCH :shock:

Ouch why Ouch. TRD will most likely ask 3K for the SC. Only benefit there is that you keep the stock warranty which sucks but you have to drop the $$ for Toyota to install it. I personally am doing everything TRD and buying an extended warranty from Scion.

Why ouch?!?! $3500-$4000.. Do you know what you could buy with that?!?!?!? :shock:

A TRD supercharger haha. I'm not saying it's not a lot of cash for most just saying that as far as other mods for the same amount of power or even close to that it's not that bad. I was looking into a TRD SC and thats gonna run me 4K installed minimum.

I thought TRD totalled the SC and was going to go with a t25 turbo kit?

TRD is working on turbo...not supercharger....

isnt 3000-4000 is a fair price for turbo kit??? well...i kno it depends on what kind of power its making..

If you break down everything piece by piece you realistically could make a turbo kit for around 2k. ..... maybe 2500...

oh...thats different story..
i think they making direct bolt on kit...maybe thats why they asking for more...

p.s. dont quote me, i dont kno anything about turbo kit...

thas true around $2500 the only thing you have to get the right piping and manifold, pretty much everything is bolt on....

If you break down everything piece by piece you realistically could make a turbo kit for around 2k. ..... maybe 2500...

If you honestly believe this, than by all means, please piece a turbo together for me. I will give you 3k which leaves you 1k for your work.


But in all seriousness, a well designed turbo kit is more than just the summation of its parts. Especially when you are workin with a motor already putting down 10:1 compression. ECU tuning alone will run you upwards of 1500 bux just for a basic map.

That's true to a certain extent. It's the returnless fuel system that's got everyone trippen out.. that and the fact that we dont know what's going on with the ecu. But if your talking about 1500 for tuning :shock: Thats more than enough for a full stand alone setup w/ a wideband o2 sensor. :shock: Piecing together a kit is easy. How well it's designed, I believe is only directly related to the quality of parts you use. What's going to make a turbo kit an OK power adder to a OMG power adder is all in the tuning. As Van said in a previous post, that is what's going to determine the difference between TRD, GREDDY, REV HARD etc...

Sorry i was at school. But that's all the info i have right now. If you guys have questions i can type to them and maybe answer your question. I want this kit really bad!

The guy from Revhard said if there was anymore horsepower the motor wouldn't handle it. But it should be okay from the info i've recieved from them.

I thought some pictures and a link might help this thread since I didn't see anyone else post them. I hope the cost isn't what they estimate it will be. I can see spending like $2000 maybe $2500 if it comes with all the other needed upgrades for fuel control....and maybe $3000 with the intercooler and all that stuff. Hopefully a group buy will bring the price down. And hopefully this kit will actually be reasonably reliable.

Looks cool. Now.....I just wish some of this stuff would actually get done........and out in the market.............where people can use it and test it.

KiL

fuel and timing management before bolting on any FI!!!

It's cool to see fmic's and turbo's but they aren't gonna run the way they should without management.

damn, that looks like a nice setup. would like to see all the details first though.

So Fresh and So Clean! But I am not turboing an auto. Just crusin for mr.

The CR is already high (~10:1), and putting 7+ PSI of boost into the manifold will result in an effective CR of 15:1.

A good tune is worth more than this turbo kit.
NO AFC Hack or FMU or additional injectors please.

Beating a gsr at 8psi isn't saying much. 14b has gone 11's :)

ok, forget the internals...has anyone given any consideration to our measily little transmissions??? they are like the size of a football....shouldnt torque them too much.

now lets have a run for fun NOS vs TURBO ok

very true and especially with the really notchy 5-speeds that we have and that recent loss of 2/4/R incident. I think if anything the tranny would be suspect.

OH MAN! that looks siick..
how much does the kit cost? i hope they start
making it available for the public really soon

FWD there's your problem :shock: :D

FWD there's your problem :shock: :D

Eh. The GSX was available when I bought my FWD, it was a beauty too. 97 low miles..
too bad they were asking 19k :shock:

Anyways as far as the rev hard turbo comes along, I got to ride in the car @ exposed. Didnt get to boost much because they didn't finish tuning it, but i can tell you that it sounds nice. They havent given out specifics on the car but i overheard him say 158WHP @ 7psi. And that's what they have done SO FAR. so lets hope tuning will up that. That is also with RHs 2.5 exhaust. They are using 2 additional injectors, and i believe a pump/regulator i think. Anyways the kit looked good. and one more thing.. sched release date is a month and a half WITH A CARB #!! :D

That sounds like great news--I'm glad at least one company is actually stepping up to the plate and at least showing us as well as giving you a test drive! of their upcoming products. I also have to give them props for showing up to exposed--this shows their dedication and that they aren't after just a quick buck...more companies should learn from this instead of sitting on their asses and making empty promises.

wait, wait, wait...I think the more important thing is how the hell did I miss this test drive you got? I didn't even see the car at el toro. Where was it and did anyone take any other pics of the setup?

I totally forgot to take pics!!!!!!!!!! :cry:

I have no idea how i got setup with the test drive. I just saw the rev hard reps, and started talking to them. Asking them about this and that. Then i asked if they wanted to see my box. Then asked if i wanted to see their box. then the driver of the box wanted to see my box, so i got to ride from the socal side to the norcal side. Too bad the tuning wasnt done, othewise i could have gotten a good 2nd gear run somewhere.

actually, runnin 7 psi on a 10:1 compression engine wouldnt warrant an "effective" 15:1 compression ratio. an engine reaches is peak cylinder at TDC as you all know, and according to Corky Bell and many other combustion engine theorists, force inducting an engine actually doesnt raise the cylinder pressure dramatically...rather it maintains pressure in the cylinder for more of the crank's stroke (which is why FI is so much better for the engine and driveable than a similar output that is all motor.) its not inconceivable to think that 7psi would work fine...especially with the reputation toyota has for building motors.

the only time i've seen 7psi not work well is with the REALLY high compression honda engine (like 11.3 and 12.5:1). just my .02[/quote]

The TRD Turbo Concept xB is listed as using a Garret T25R and 7psi of boost. No word on if the engine or tranny is beefed up to support it though.

Well since all the stuff we get comes from toyota marketing, you should get the same thing. Instead of brochures for toyotas we get magazines for Scion. I think everybody has seen them at some point. 1/2 the magazine shows off the car, flip it upside down and the second 1/2 is all about art, music, & events. First issue of it I saw came with a sampler cd (dvd maybe?). The latest issue of it we've gotten shows off the tC mainly, but it also shows some more SEMA cars, and has a picture & blurb on the turbo concept xB. Rummage around, all dealerships are supposed to have these =P

I haven't seen it, but I did meet the xB owner, Tim, from Revhard in Phoenix for IDRC.

He has a white xB with gold GT-N's. His car was at El Toro

I think they are shooting for 3000-3500 with FMIC and fuel management.

Can't wait.!

Will this work for a Xa also? i

Engine Management is key.

Looking at your pictures one thing seems to jump out.
They are going to have to work on the hard pipe routing some more too.

If it won't fit with the "factory" accessory strut brace then it is not going to be successful.

Particularly when us RS1 owners all have the strut braces and a bundle of the regular xBs do to.
