My recent build. 93' SC300
 

After my bro crashed my SC400 (which was about to go turbo) I ended up parting the car and selling all the turbo stuff I amassed. A little after I ended up buying an SC300 this time. For about 2 months we worked on this thing and knocked out quite a bit of work... During winter, outside in the cold. My garage was full at the time. The car was on its deathbed and we decided to save it.

Mods:

t-61 turbo kit from XSPower
Godfather Dish III Wheels
Tanabe Springs
Custom leather interior

We're still working on a few more things and getting the car painted and all that good stuff. Im mainly waiting on my meth injection kit so we can turn the boost up to 15 PSI.

Looks good. Pre-OBDII is the way to go. Lets us know how the Chinese turbo kit works.


I wish my IS300 was that easy to tune :'( :(

Re: My recent build. 93' SC300
 

looks good

Re: My recent build. 93' SC300
 

WOW your car looks great after youve gotten done with it.

Re: My recent build. 93' SC300
 

Thanks guys,

Yea the OBD-II is no fun to tune unless you go with the AEM standalone. My buddy just finished his 96' SC300 so we're getting ready to tune that.

So far the turbo has been running great and the spool is insane. Full spool is at about 2,500 rpms. Been using the car as my daily so it gives me a chance to do a bit more fine tuning.

Re: My recent build. 93' SC300
 

buk <3's you nice car

Re: My recent build. 93' SC300
 

that turbo doestn suck ---- up :-X

Re: My recent build. 93' SC300
 

I don't think that even qualifies for hmt. That thing is fricken sweet though I love the pic from the front.

Re: My recent build. 93' SC300
 

HMT is anything you don't buy as a kit. Ideally you weld all your own parts, but not always.

I'd like to know what you've done as far as tuning goes. I'd assume you bought a chip, converted to the turbo wiring/ems, or have some sort of piggyback?

Re: My recent build. 93' SC300
 

Thanks!

Well my original projects when I first arrived here (94 camry and sc400) were going to be HMT's, they failed misserably since i sold the first car and my bro crashed the other one. After I got the 300 my original plan was again to do a custom HMT but I got a great deal on the kit and couldn't pass it up.

As far as tuning going. Fuel is completely stock and so is the ECU. Right now im using an safcII which does the job fine. I would like to delete the maf eventually and go with the emanage blue again.

I tried an emanage blue without success. For some reason the karman maf hates it.

I didn't do a headgasket but the 2j can handle about 7-11lbs without really breaking a sweat. I plan on adding a meth kit so I can run around 15 psi and eventually I'll upgrade the head gasket.

Re: My recent build. 93' SC300
 

FYI I recall an article about some Chicago SC300 turbo, silver too. The guy was at 450whp IIRC, and was rebuilding another stocker to take past 750whp. All he was altering was the HG thickness and shot-peening the stock rods. He said the current record for the non-turbo motor was about 700whp...

Still that motor at 7psi with a T67 is probably over 400whp, 500+ with perfect tuning. Nice work :6

Re: My recent build. 93' SC300
 

Awesome, love the restoration. That car was really beat when you got it. Under the hood looks amazing. Got any videos of it yet? I want to see it rip. :y

Re: My recent build. 93' SC300
 

I've got an IS300 that I'd loooove to boost. Maybe one day. Sweet project :6

Re: My recent build. 93' SC300
 

How much boost are you running? I have heard of guys running the SAFCII on the IS but supposedly you gota reset the ecu everytime so it wont "learn" and lean you out. Some dudes run a fuel only unit so the ecu won't trim fuel overtime. (haltech F10x, megasquirt, ect.) I am told that up to about 15 psi, the ecu timming map is sufficeint, although I would only run 7psi on stock timing for saftey. 7psi though will "turn ya out"


Those wheels are fucken wicked, love the deep dish look.

Re: My recent build. 93' SC300
 

Not bad, post up some vids of the bad boy.

Re: My recent build. 93' SC300
 

I'm running 7psi. For you IS300 guys interested in doing a setup check out clubna-t.com i know there are one or two guys on there who went turbo. They did talk about resetting the ECU since they are OBD-II but I think one of them went standalone.

going to have some vids soon. Still taking care of a few small details. We just finished replacing the tranny solenoids a few days ago. took my mufflers off the other day and it sounded great. Not overly loud but deep and mellow.

Here a vid of what it sounds like: Its basically the stock exhaust with 2 stock resonators and 1 cat. All i did was pull the mufflers.

Re: My recent build. 93' SC300
 

sounds pretty beastly. which is sad considering all you did was pull the mufflers. you gotta get it al finished and take it and run a quarter.

Re: My recent build. 93' SC300
 

Yea i'm itching to take it to the track especially since I kept the stock compression ratio. Just waiting on the meth kit before I do my final tune and head out to the track.

Re: My recent build. 93' SC300
 

Sweet

Re: My recent build. 93' SC300
 

looks great, very simple too.



sucks you had to hack the bumper that way, could be a total sleeper

Re: My recent build. 93' SC300
 

Next best thing to a supra.

I bet that thing hauls ass....

Soarer love.

Re: My recent build. 93' SC300
 

Props on the build! Id stay away from the emanage though. Ask Joseph Davis about the n/a-t mkIV supra he tuned with emanage. It was full of fail. :6

Re: My recent build. 93' SC300
 

Would MSNSV2 do anything for him?

Re: My recent build. 93' SC300
 

MSNV2? Is that megasquirt you speak of? I have toyed with the idea of doing the fuel only option for around 7psi. For the price of mega squirt, I can get an AEM f/ic to do the same and not ---- with the stock fuel drivability when in vac. I would like to do the megasquirt though so I could get a better understanding of how it all works.

Re: My recent build. 93' SC300
 

MAP ECU 2 is for the win. $700 bucks basically a standalone and easy as ---- to use. Google map ecu. Its Plug and play for the supra id imagine a soarer would be damn close if not the same harness.

If I didnt already have (read: borrowed) an AEM for my supra thats what I would have.

Re: My recent build. 93' SC300
 

I have heard some great things about Map ecu. Some dudes have run it with ODBII on the IS and had mixed results.

Re: My recent build. 93' SC300
 

The problems they have are the stock ecu fighting the map ecu for control over the VVTI, just lock the ------- cams in place and crank up the boost. Simple fix. :6

Re: My recent build. 93' SC300
 

XSPower turbo kit? Meh, you are brave.

You can get 1020 Honda boxes for sub-$500 if you put an ear to the ground... they have all the coil and injector outputs required to flash with the 1100 (2JZ-GTE) base calibration and work correctly, just requires an adapter harness.

All the Supra guys are rich dildoes with a lot of money and no clue, if you ever go COP/GTE setup with an AEM, which reverts you to wasted spark, you DO NOT HAVE TO BUY AND HKS DLI OR MSD COILS FOR A THOUSAND DOLLARS so don't listen to the forums. Get a hold of me and I'll walk you through.

Re: My recent build. 93' SC300
 

ching chang failure in future

Re: My recent build. 93' SC300
 

and i just put my sc up for sale since i had my del sol stolen :(

Re: My recent build. 93' SC300
 

NICE! how much did it cost to bring it back to life?

Re: My recent build. 93' SC300
 

I redid a few things over the weekend which changed the whole feel of the car. I've got the karman maf which doesnt like metering boosted air.

I changed it to a draw through setup. I also installed new copper plugs (properly gapped) along with a walbro 255 and the car pulls like a bat out of hell.

2psi on the new setup feels like the 6psi I used to feel when I had the maf in-line. I'm hoping to get to the dyno this week for final tuning and some hard numbers. Going to run it at 10PSI.

The car cost me around $2,500, but also came with a lot of replacement parts I needed + some extras.

On top of that I spent $1,000 on the turbo kit, $500 for gauges and $450 for leather. Figure another $500 for misc stuff like tune up supplies and what not.

So grand total figure: $4,500


That sucks, sorry to hear... Someone called me car a del sol once... Weird.


I get that A LOT. Honestly, I've seen the kits in action and thats the only reason I got it. I know quite a few folks running the kit and they've had no issues for months. A few supra guys even run the kit without issues. A local buddy was running the kit on his 1jz and eating everything in sight. Making just a little over 525wrhp @ 25psi with meth.


lol thanks


The emange is a pretty solid unit I think. I've had it on 2 other cars and I know a few guys that ran them. Either way I couldn't use it since my MAF didn't agree with it. I'm pretty happy with the AFC, for now.


Yea its a really solid car. It does haul ass... lol.

Re: My recent build. 93' SC300
 

Do you have a return fuel system? or returnless? So the SAFC working good? stock injectors? No fmu? Did you do any mods to the trans? (valve body mods or what not)

Keep us posted on this, it gives me hope and knowledge of what I and a few dudes with an IS can do. I love the SC300s but they are getting harder to find. Looking forward to your dyno results.

Sounds like I need to change my computer to an odb1 (for fuel only) and run that setup if its working good for you. I always knew that engine could be turbocharged cheaper than all the jdm nutswingers an the forums at My.is

Re: My recent build. 93' SC300
 

I respectfully disagree. The technology is dated and their are much better options for the money these days. MAF translator PRO is one such option, as is a honduh AEM or even map ecu1. None use the karmaan vortex maf sensor and all will have the capability to tune your car far more safely than the emanage or an afc. my $.02.

Re: My recent build. 93' SC300
 

Rob, it's a 2JZ. He can hammer it with detonation daily for the better part of a year before he needs to start thinking of doing something better before he hurts something. If you owned one you would know this. :P :P

I swear I could field a reliable 7 second 2JZ-GE drag car running an FMU.

Re: My recent build. 93' SC300
 

Go boil some water.

I dare you. Ill provide the car, you provide the FMU. :6

Re: My recent build. 93' SC300
 

I should have said for the price I got it, it was a pretty soild unit. lol. I do agree there are much better options that are cheaper now. For simplicity I went with the AFC. For an upgrade im looking at the AEM or the MAF-T Pro.


The fuel system is a return system. The SAFC is working great so far. Stock injectors. No FMU/FPR. No mods to trans since it can hold about 350. I plan on upgrading to the 1jz tranny which is a direct swap and holds much more power. I do have a walbro 255 in there along with the 12 volt mod aka fuel ECU bypass, this allows the fuel pump to see a constant 12 volts.

Re: My recent build. 93' SC300
 

Thanks for clarifying. I did'nt know the 1jz had a better tranny, I will keep that in mind. If I could get around the ODB2 for fuel I would be golden. Unfortuneatly I have the DBW (electronic throttle to a point) that the ecu presently has controll over. Do you have a tranny cooler on? I run one for preventative measures at the moment.

Is it possible to run a pre odb2 ecu (95-96 and older 2jz) in paralell that would control only fuel? I guess this is the wrong section to ask.. :1 If your SAFC is working good for 7 psi with that ecu, a used 93-96 ecu is probubly cheap at the bone yard to be used in conjuction with a cheap and simple engine mgt device. Most of you guys are not fans of this time of engine mgt but some of us are not graced with either a chippable ecu or a "reflashable" ecu. I am surprised that noone has marketed one for the IS as it seem like alot of people are interested in modifying it. Sometimes I feel like selling the IS and getting a honda.... :-[ :'(

Re: My recent build. 93' SC300
 

There is an OBD1 conversion which is pretty simple to do. The only problem is your car is VVTI. No clue how and if that conversion would work with that.

I'm running no trans cooler at the moment, but I have one that I will be installing once I get some time.

Right now the AFC is working great, easy to adjust and tune with.

There was someone on clubna-t.com that was working on getting a dual ECU setup going, so thats something you may want to look into. Check out the website, a few IS guys are on there and I know 2-3 have boosted VVTI motors. I believe one guy built a track IS so its pretty much gutted. It looks sick.

Re: My recent build. 93' SC300
 

Thanks, I will check out that website. I am assuming the stock ecu would still handle the VVTI, just hand the fuel injectors over to the other ecu (let the stock ecu control timing). I think once the price comes down a bit more in the IS and maybee some of the newer SCs and GSs, more fruits of experimentation will be had.
