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.

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.


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.

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)


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.

QUOTE
so just replace the stock fuel pump.... and i can run 8psi on the stock injectors...


8psi yes, any more and you'll need bigger injectors as well.
