I've created this thread to see if any of you have any ideas on what I can do and what's available out there to go from my TRD supercharged setup to a turbo setup.

Is there any way of losing the TRD reflash besides buying another ECM?

As of now it's an 09 Scion tC with 30k miles:
-05/06 rebuilt TRD supercharger (stock pulleys)
-Aftermarket a/n oil return line
-TRD fuel injectors (410 cc/min)
-TRD stock-like box intake
-TRD ECU reflash
-TRD axle-back exhaust
-AEM wideband O2 sensor/gauge
-(NGK?) Heat range 7 spark plugs
-TRD 160 degree thermostat (for radiator)


As for turbo parts I have:
-Precision SC61 turbo t3 flange (journal bearing)
-May stick with the TRD injectors if duty cycle is no more than 85%

For the turbo manifold I'd like to go with an equal length, but nothing crazy, and I prefer to have leave the stock exhaust (might remove the TRD muffler)

I plan on getting a bov like the HKS SSQ and make it recirculate to keep the car running smoothly

The amount of power I'm looking for is any where within the 200-300 hp range, just want a little more power and fun. There is as far as I know, nothing wrong with the TRD supercharger I have now.

I've run Royal Purple 5W-20 since the 3k mile mark and strictly change oil every 3k miles along with TRD oil filters.

Thanks ahead for the input

The injectors may be a bit small, but should be good for the low to mid 200's horsepower wise. The oil pan should be good, just get a return hose with the proper -AN fittings. I think your best bet would be talking to the guys at Descendant and going for their tuner friendly kit:

I know of their kit and ptuning's, also Sikky for them having built some nice drift cars, and my cousin who bought some parts from them to build an LS1 240sx (s14 style) which are some of my top picks since I've seen what they've done through competitive sport and filtering that through to the customer.

I would go for a kit, but I have the turbo already. I'm really just in need of intake piping setup, maybe some info on what size i should go for, do i need at least an aftermarket s-pipe, which would be an easy and reliable piggyback (standalone no, because it'll be driven everyday and not tracked much at all). I want two-step (do i really need it for a good take off?), adjusting rev limiter, good boost controller, filter off turbo or extend it and go cold.

Most importantly, who should i go for a good street tune.

Looking for ideas/brainstorming, but thanks for the input emrules2001

If you want that power get methanol get the smallest pulley you can get from nst and engine management and you will be in the high 200. When I was s/c I made I think around 275-290 Dont remember. Exactly but made it there with I just stated. Gl

Cant really comment on the rest, other than IMHO that turbo is a bit large for 200-300 whp goals As for a piggyback, Id go with the Eman Ultimate - it does everything youre looking for (2 step, increased rev limit) and is a GREAT unit. It took me awhile to get used to mine and work some kinks out, but after that, this thing is amazing - Im still discovering new things it can do However, if you plan on sticking with stock motor, I wouldnt plain on raising the rev limit over 6800 ish if you want it to be reliable.

ScitC

Thanks for the info

I don't think I'll be raising the rev limiter, but a piggyback that can do more is usually better from what i understand, and has an expansive mapping ability. Yes I know the turbo is like a garret gt35 or so. At least it'll spin slower for what it's made for, so it'll work lol.

The emanage blue and the aem fi/c are the two i am looking at so far.....
What do you know about the AEM fic? Does the extension harness 30-2998 work with my 09 or just 07-08 as it states? Do I need that harness?


Thanks

paul_dezod

I have helped numerous customers do the same thing. Give me a shout when you get a moment.

rhythmnsmoke

Emanage Blue nor the AEM FI/C do what you are asking.

SC06TC

what was the verdict about the TRD ECU reflash, removing it that is?

ScitC

Sorry I've been off for some days.

What do you mean? The AEM can't perform the 2 step/launch control, even as an add-on? I called them over the phone and they told me it could?:?

SC06TC I'm trying to figure that out still. Might have to find a totaled tC and swap out the ecm. (Junk yard) Calling TRD is useless, they'll just say it can't be undone. Guess this is prolly the biggest issue...

Does anyone know what the TRD clutch is good for TQ or HP wise?

Paul, you should put information in this thread if it's technical, it may help a lot of us out here, even those going from n/a to turbo.

rhythmnsmoke

The AEM EMS (standalone) has two step launch control. The FI/C does not. Nor does it have rev-limiter increase and speed cut removal. The Emanage Ultimate does.

ScitC

Calling those guys over the phone sucks...Asked AEM about their FIC, guy told me yes to all I asked above....And I Called TRD yesterday to ask them how much power can a TRD clutch hold, waited 15 minutes to hear him say "ask a toyota dealership", and i was like that's me!!

ScitC

Small update....

I went ahead and ordered a new ECM which came in yesterday. It was installed earlier today. Supercharger is on the car still but not spinning as of last night. All I'm going to do is cap the oil pan and take the rest of the kit off to be sold. Already have a buyer, just hope he buys like he said.

For the tC I have:
Agency Power light weight oem size crank pulley
Aem Uego
TRD thermostat
TRD high strength crank bolt
12 an weld in steel bung in oil pan(will be capped for now)
AEM F/IC 30-1910 not yet on car (need harness)
GGP Engineering front engine mount (not on car yet either)
Autometer mechanical boost/vac gauge
Autometer (short sweep?) oil pressure gauge (not on car)

I've looked through SL and other forums and so far I'm thinking of getting:
Descendant Tuner Kit
HKS ssqv with recirculation fitting

Change spring to 10 psi

BlackKnight

Really? There is no additional stress on the crank bolt as it just holds the pulley on for the most part and from what I remember when putting an ATI damper on mine, the bolt is already at lease a grade 8 bolt.

ScitC

Well it was already on there because my car was supercharged. I rather leave it because it's TRD lol and makes me feel more comfortable knowing it's stronger. And I'm pretty sure that when you increase power it will cause more stress on the crank.

ScitC

I forgot to mention that everything is working great and back stock with the new ECM.

On the tC I have:
Agency Power light weight oem size crank pulley
Aem Uego
TRD thermostat
TRD high strength crank bolt
TRD axle back
Goodridge 12 an weld in steel bung in oil pan(will be capped for now)
Autometer mechanical boost/vac gauge
Megan Racing 4 to 1 header with Design Engineering Speed Sleeves

To be put on the tC/Already have:
AEM F/IC 30-1910 not yet on car (need harness)
GGP Engineering front engine mount
Autometer (short sweep?) oil pressure gauge
Precision SC61 T3 flanged turbo

I've looked through SL and other forums and so far I'm thinking of getting:
Descendant Tuner Kit that'll have the HKS bov flange and will work with the T3 SC61
HKS ssqv with recirculation fitting (for looks and quality)

Change wastegate spring to 10 psi when I get tuned

I recommend starting at a lower boost level like 7-8 and then work your way up.
I don't think you be able to command enough fuel with 410cc at 10 psi.
SC61 will have moderate boost lag but nothing crazy but doesn't the tuner kit come with a turbo. A spare turbo is never bad.
You should be on your way to being happily boosted keep us updated.
Good Luck.

ScitC

I plan on getting tuned at 7-8 psi then up to 10 psi or however the tuning shop I go to wants to do it. Not to picky on if I make 250, 270, 300 in the end, just want the tune to be refined and oem-like.

I'm selling the 410 cc's with my supercharger kit, so I'll def be going bigger like 550 cc's or higher to be safe.

For the Tuner kit, I'll probably have to call Descendant and ask them to leave the turbo out and AEM FI/C but send me the base tune. I'm sure they and I can work something out. The SC61 I have looks really cool though I know it's too big for my goals lol.

Thanks GUNNIST14

What do you guys think of getting some kind of JETHOT coating for the manifold? And wrapping the hot side in a fiberglass blanket? Worth the cost or worth my amount of boost (10 psi)?

GUNNIST14

iTrader: (1)

Anything that reduces the temp in your engine bay is worth it no matter what.
Coating the manifold is a good idea.
Turbo blankets or heat shield improve turbo performance like adding 3+ tq and 1hp gain so they don't hurt and give the setup a clean look.

This is my setup before I KO'd

ScitC

Ok sounds good GUNNIST14 and nice engine bay, that heat shield makes your setup look clean. It sucks that your engine blew (assume that's what ko'd means?) But I hope you hop right back on and get it running again

Only downside I think for heat reduction will be cost and an even more elongated not being turbo'd time lol.

I have another question. I was looking at RC Injectors and couldn't figure out which 550 cc injector part will work with the tC? There's a SL4-0550 part number and an SL9-0550 part number, which will work? Should I just get the SH4-0750D (Denso style top) because it says Denso style top and the tC is mostly Denso?

Thanks in advance
