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

 

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?!?!?!?

 

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 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.
