I got kinda bored at school today and started looking for 7a-fe turbo kits, the only ones I can see are the corollas. There should be no diff. between our engine and theirs right? So technically a corolla turbo would work on a celica st? Also, what do you guys think of turboing a car with almost 100k miles on it? I don't want anything insane, maybe 6-8 psi, just something to give the car the kick in the ass that it needs.

i went custom
just dont forget a fuel pump LEARN FROM MY MISTAKE!!!!!!! the ST-T is a very fun car to drive, i really miss it, and when your car was 100% stock on the outside except 17 inch wheels, it makes a great sleeper. -------------------- 1994 Celica GT4 WRC Edition

What kind of horsepower increase did you get from the turbo. I am going with that turbo kits kit and I was just wondering about how much will I gain do you think. I got a g-tech so Ill be able to tell once I put the turbo on I would just like to have a number to look forward to.

my guess is the 170's but you'll need an air\fuel computer to keep from getting detination.

i was a 8psi when the piston melted
but the problem was caused a few weeks earlier when i got the new turbo on there, the spring on the new actuator was of a different strength. i had everything set the same as with the old turbo, and expecting 5psi, the boost went up to 10psi in first and spiked to 12 in the 1-2 shift that was not a problem for the engine, but the stock fuel pump gave out(12:1 FMU times 12psi, makes for a 144psi increase in fuel pressure, too much for the pump to handle) car had a lot of detonation, a few weeks later i was making some runs in an industrial area of town and i cruised, made a u turn, came to a stop, and the car started shaking badly. i was making a lot more power than stock, from 15mph to 115mph the car would not stop accelerating. i used to go from 0-115-0 in around 45 seconds, rolling at 40, just under 4 seconds at WOT and i would be at 80. take an auto ST and see what speed you hit after 4 seconds of WOT from 40mph, i think i manage 50mph now, lol from a roll, lightly modded mustang GT's were no problem(even from a stop, i would pass them by the end of second gear), no NA honda(that i came across) stood a chance, celica gt-s owners learned to pay respect to older generation celicas, and one 6gc GT owner learned to not judge a car by its badging  i would say, that compaired to a stock ST, at 8psi, i had an approximate 100% gain in power(@crank) the best part was that i STILL GOT 23-25MPG in city driving, 30+ on the highways because i had a t3 turbo, it was easier to drive around with out making any boost at all. the small turbo's that come with those kits will spool faster and more easily. they also will run hotter, but on a mild setup, it wont make much of a difference just remember, if its for a corolla, then its not going to be 100% bolt it. charge piping/intercooler piping will most likely not work with out modding and im very sure that the downpipe wont bolt in place. -------------------- 1994 Celica GT4 WRC Edition

well sence this is alreadyt an open topic, why wouldnt you just want to do an engine swap, i mean 220hp stock.. and its made for the boost, wouldnt that make more sence?? an how much exactly are the cost for just turboing or re-build an turbo?? Thanks

if it cost the same, then yea, that would make more sense. but an engine swap? do u kno how much longer that takes? lol. ask anyone who has done it. its not a 1 day project. we're talking about car downtime enough to do alot of damage to ur schedule. especially if its your only means of transportation. after the whole swap with the 3sgte, ur looking at 4,000 bucks at the least. corolla turbo kits come to 1550 for the bare bones kits, probably bringing u to 140 or even 160 if you buy extra parts like the intercooler. plus these kits are bolt on, day jobs. 2 days at the most. but if ur willing to spend more than twice as much moolah and can drive a rental for awhile then cool. thats really neat  but i cant. my car is my baby (well 2nd to my gf) and we roll everyday. and play everyday. maybe later ill treat her to more

Have you done either? I think you're seriously underestimating the time it takes to turbo an ST. I've been working on it for over 6 months and I'm not there yet. I'm pretty close, and my setup will be top notch, but theres a LOT to it. The cheapest you can do it is still going to be over $2k (not $1500). I think its really a toss when it comes to the swap vs. the turbo. It really depends on what you want out of it in the end. The swap is more expensive, but can yield higher power numbers with less work (and less additional money past the initial work). The turbo is cheaper but a lot more complicated if you're not experienced in such things. Yes, the wiring in the swap can be tricky, but now you can just send the harnesses off to Mike and have him do it all. That makes it a LOT more simple. I wish I would have done the swap now, but I think I'll be really happy with the results I get with the turbo.
Did the pump actually stop working for good? Injectors are simply not made to withstand much over 100psi. 144psi would have stuck them open (if the stock pump could have produced it) and caused all kinds of bad things to happen. More likely the stock pump wasn't ever capable of 144psi (very, very few pumps will do this under ideal conditions). You probably ran out of fuel pump at just under 10psi, went lean, and burned the piston. You really really really needed bigger injectors (and therefore lower fuel pressure) with a higher volume pump to keep things from going bad. So you're partially right, the fuel pump would have been great insurance at 8psi, but without bigger injectors, you would've been screwed at 12psi anyway.
8psi yes, any more and you'll need bigger injectors as well. |

john,
the piston didnt melt till a few weeks after i changed the fuel pump. althought i am very sure it was severely weakened buy the failure of the pump. the pump didnt completly quit, but it would cut in and out when under load that pressure was only a guess, going by the ratio of the fmu and the psi that was made at the time most likely the pressure rose to a point where it overloaded the pump, made it shut down, then detonation. what it felt like was the car accelerated hard and fast, then felt like i had let off the gas, then came back on, and repeated the process in a matter of a few seconds. i pulleded over as soon as i realized what was happening and bypassed my MBC which made the car run at 4psi, but the damage was done the compression test was 209, 0, 180, 207 before toyota pulled the engine and put in a new shortblock under warranty i got to look at all the internals and everything was in good shape, even the rings on the #2 piston(the one with 0 compression) were intact. i think that 8psi is a good level to keep things at with the setup i had, as with other similar setups. honestly, i never wanted any more than that, it was fast enough for me. -------------------- 1994 Celica GT4 WRC Edition

Very interesting. Head gasket then? A melted piston or a screwed up ring would have been very obvious, as I'm sure you know. |

yea, the HG was ok too
i was very impressed considering i drove the car 20 miles after the pistons melted did you not see the pictures i posted? you could look thorugh the #2 piston and into the oil pan. it was bad, but i got a brand new short block for $0 This post has been edited by 97sccelica: Apr 6, 2004 - 9:53 AM -------------------- 1994 Celica GT4 WRC Edition

Ok heres my deal. I am getting the the "extreme kit" from turbo kits.com I am not trying to sound like a badass by getting it . I just as many of us think our cars look great run slow. If you could take a look at all the extreme kit comes with and tell me what else I need to buy. at the same time I am getting the kit I am also ordering an apexi SAFC just hit me back with what you think I might need. also what psi will I be able to run safely on the turbo kit once bolted on. Then hit me back with what else is needed and how many psi you guys think it will run. In my town there are some punk ass kids who think they are the **** and I have one of the nicest looking cars in town so everyone wants a race. I am not trying to say my car is the nicest by any means but in this town we have kids with like a stock 84 civic with absolutely nothing on it thinking they are the ****. I know I can beat them now I kjust want to be able to run circles around those bitches. Also I bought a g-tech so my horsepower on my st is 127 right now hit me back with what you think the turbo and intercooler with hit me with. Thanks

Also the turbo kit I am interested in comes with an injector control unit with two more injectors do you think that will help with the leaning out problem?????

there is only one fuel pump that i know of that is a good price and fits fairly well and thats the 255lph walbro pump for a mk4 supra TT, $90 on ebay will that kit be reliable, ask on some corolla forums for better answers, but i would hope it is, if its a complete kit sold by a company 7afe @ 8psi should have no problems, if the fuel system is modified to meet the higher demands(since the kit comes with injectors, then it should be good) but like evil said, the whole black box thing is a limiting factor, and since we dont know what it does exactly, who knows if its the best for your engine in your state, with its weather. -------------------- 1994 Celica GT4 WRC Edition

In preperation for the turbo, my pump has been on for several hundred miles. I'm really suprised how quiet it is! I really expected it to be louder. +1 more for toyota engineering. |

There's all kinds of other details other than a cost per cost comparison. Stuff like getting around emissions (if your state has them) and downtime. I know with a turbo, at least my car might be down for a weekend maybe rather than months. I don't know about everyone else, but my Celi is my only car, and if she's not running, I'm in a heap of trouble - so cost for a 3s swap for me would mean paying for all the swap stuff plus the cost of a second car... |

That is the link I found for the walbro fuel pump. It says its good up to 500hp. The question I want to know is. . . How much boost can a 7a-fe take before it blows. |

depends on how much money you want to spend
get the fuel system to support 15psi, and have a way to control ignition and fuel, and you should b able to drive the car, with a reduction in life expectancy, but not necesarily blowing the engine. anything that cools the intake charge more and lets you put in more fuel will allow for more boost. fmic, intercooler sprayer, water injection, menthol(sp?) injection, bigger injectors, better fuel pump, performance FPR, engine management. it all helps, that and dyno tuning. -------------------- 1994 Celica GT4 WRC Edition
