Turbo and ems questions.

[aznguy1384]

Ok guys let see if i can get some much needed help from you guys.
ok current status.
i4 solara, unfortnately auto.
lower, rimms, the usual visual aesthetic features.
I was thinking about doing the intake, header, and exhaust thing. But it dont think it's worth the 1500 for a few hp.
so the next major thing of course is boosting.
planning:
Bascially pulling alot of parts from a mr2 turbo engine.
ct-26, oilpan, exhaust man., down pipe, a couple of other stuff.
I can get that stuff used for under a 1000, easily because there are alot of used parts.
but the one problem is the EMS. that's what i need help with.
I obviously dont want to spend alot of money, but do i really need a new ems, or can i some how mess with the fuel.
and i am in california, worse state to be in if you want to mod your car by the way, so i'm sure this isn't legal.

another option is of course the RIPP mods SC, but can some one tell me if it is legal in cali.

and in both cases the boost will be low, around 9. 5sfe cant handle more, or atleast i dont think. so the sc or the turbo, will the whp output be the same, which is more effiecient.

so guys any comments or helps would be much appreciated.
Thanks.

You can use a Apexi SAFC/SAFC II, Greddy E-Manage, etc..

For what your doing you don't need a full out standalone computer.

And your correct, your car is no longer going to pass smog. Theres ways around it though, but thats all I'm saying.

Contact them and ask.

Turbo is more efficient. If you compare compressor maps for both, you'll see that turbos are more efficient.

Superchargers cause parasitic drag. This is because their driven by the crank. In other words you lose power to make power. How much power you lose depends on the supercharger.

You lose some power with a turbo too, but its nowhere near as much as with a supercharger.

I'd take a turbo over a supercharger anyday.

once again, just buy my car.
or i can sell you my turbo kit, but it will require you lots of labors.

btw, solara has returnless fuel system that would require you modify it to return prior for turboing. I had 185 whp & 187lb torque on the wheel with 91 octane, but i am going to get a new dyno soon with improved exhaust and maybe better octane. At this moment i cannot compare the power figure with rip kit because i dont know what kind fuel did they used for dynoing and they never response to my question.

Also, turbo or supercharge your solara is illegal in CA. however, i can sell you the car with smog done.

Those are AMAZING numbers with the 5SFE... congrats!

[aznguy1384]

I actually saw your car on ebay, very nice by the way.
185whp huh, what psi are you running?
You also did a rear disk brake conversion too right.
What type of turbo is on your car?
did you do the Toyota Burien kit or the ct-26 swap from the mr2.
I would love to buy your car only, i'm actually trying to get more out power out it, but it seems like that would be unlikely. so far the 5sfe is puttin out about 180 to 190 whp give or take, with either the sc or turbo.
also i actually dont want to go through the hassel of gettin a new car.
not saying that anythinig is wrong with it, it looks really nice, i dont know y you're selling it.
thanks for the offer though.
If anyone is thinking about selling their mr2 or celica all trac turbo parts i might be interested.

[UltraslowSolara]

It was completely customized with T3 turbo with front mount intercooler. The Burien kit is very incomplete and come with a smallest turbo. 3sgte maniford was not considered because the shop promised me to bulid a complete kit (which is not, i have to complete it by myself).

the 185 whp was boost with either 7 or 9 psi. I spend 7G on the turbo kit alone. The reason behind that is that if you want it runs right, you cannot go cheap with it. If you dont plan to spend too much money on the car, then you might better give up the turbo idea. you may look at my mod list and start add up the price and see if that meet your budget range. howevre, here is two important concept about turboing the post-97 5sfe..

The 190 whp curse can be easily break. I obtain my number after 9th run with extremly hot motor after tunning. Also I still had one of my cat-convertor on my 2.5" exhaust (should have gone to 3" but no money right now). Also my old clutch with 69000 miles. If i have those stuffs replace, i should able to reach 200hp.
Also the post 97 5sfe is suprisely durable. I been boosting for 3 years and 39000 miles, my car still runs perfectly and no engine problem. I used to have oil leak problem on my oil pan but it was becasue the oil pan was facked.

here are two issues you should keep in mind..

1. running returnless system is not safe for turboing. i heared many turbo celica killed their motor becaus of this

2. The better air fuel management you get, the better it is. Beside that, you also need to spend quite huge amount of money to dyno tunning the car (300-700).

I am selling the car just because i need to be more focus at school. another reason is that I just get tire of it because i like to mess with different cars. The next car i get i want try VIP style. So i would either get some used lexus or infiniti.

I owned
95 dodge neon -> first car
90 Integra GS
92 Isuzu Amigo
95 Mercedes C220
00 Toyota solara -> current, chilled in garge
86 Toyota GTS
95 Nissan 240sx
90 Nissan 240sx -> current, no time to fix steering problem
92 Civic CX hatchback -> current -> daily beater, future project car for my bro

The reason i say just buy my car because after i read your cardomain site, i realized your ideal solara is very close to my project. However if you saw my ebay ad you should know i spend $14000 on modifications. So buy my car will be the fastest and the cheapest way. Also you can save the headache for auto to manual conversion.

[aznguy1384]

yeah i saw that you did do alot of mods to your car, even the custom manifold with even tubing. you dont know how much i wanna just drive my ass over to riverside and pick it up bro. But unfortunately i cant sale this car. the turbo post was just a thing i had in mind. and yeah i totally agree with you on the expensiveness of turboing a car and tunning it correctly.

I will definitely give you credit on the mods for this car, it's filty nice man.

[UltraslowSolara]

Thanks. I am not forcing you to buy my car or shits like that, i just want to give you a heads up. Because i seen many incomplete or failed project. many people like me has no clue what we are involving in before we start the project.

also nor cal and southern cal is not that far....

[aznguy1384]

Central Cali, Santa Babara, not that far away at all.

hahaha didn't say you were forcing me.. but i will say this, if i could buy i be down there 2morrow. And thank you for the heads up. but every turbo project that i've seen has turned up around 5 to 10k. so turthfully i'm not willing to spend that much right now. i'm pisssed trying to find blue blubs, but bright bulbs for the car. besides going hids any sugestions. Read some stuff at solara guy, all stated that piaa pretty much sucked. and that the best upgrades are silverstars, which i have already. but i'm actually gettin some led corners, coming soon, so i want the blue tint to match. but all of these damn shitty blue bulbs aren't bright enough. i would love to do the hid thing, only i'm sure it blinds everyone and cops are attracted to it.

Oh yeah, one more thing, i would totally spend the money on the turbo, or buy yours, but im planning to save up for a nice ass m3. dream car.

[aznguy1384]

Hey guys, i'm not sure if this was posted on the forum already, but how well would the 4 cyl auto tranny hold up with the new power of the turbo.

I actually found a turbo set for a really good price, most of it from a mr2, exactly what i wanted. But i'm wondering if the tranny will hold up. Basically do i need to do a tranny swap. i've heard alot of good things about toyota trannies, so i'm hopping that it will be fine.

how did you convert your returnless fuel system to return style? Did you take the fuel rail, fuel pressure regulator, fuel lines from the 3sgte? Does the 3sgte fuel rail bolt to the 5sfe head?

Is it a known fact that the returnless fuel system is no good for boost?

[88 LE]

^ You have to modify (drill and tap for fittings) your existing fuel rail, get a aftermarket fpr (fuel pressure regulator), and run lines to the fuel tank.

Returnless fuel systems suck.

[UltraslowSolara]

I paid $700 to let a professional guy done it for me with a 3SGTE FPR and E-manage installation. if you are inexperience with car, i would say dont mess around with the fuel system.
