Successful turbo 5sfe stories?
Posted 02 May 2010 - 10:25 PM
You wouldn't have to get an engineering certificate either (as the engine blocks still the same as what came out)
They may wonder why its idling like a bastard though haha

There seems to be some myths as to turbocharging the 5sfe... couple of key points, the standard ecu will run a boosted 5sfe, and it is great fun to drive, doesn't detonate, some people need to see the proof, its in my driveway.

yes pics are mandatory when i clain like that is made.

I don't have a pick of the engine here on my phone but I did upload a video of when she went up on the dyno, on Brisbane Celica club cruising page on fb

I agree with Rev_head, Consider getting an aftermarket ECU before applying extensive engine mods....Toyota ones aren't tunable by your average DIY tuner.
I noticed someone mentioned detonation....
If you have a 1993+ 5sfe engine it comes equip with a knock sensor, so detonation isn't going to be a huge deal.....however if you have an earlier model this may be an issue.
I have this in mind for when I build a 5s-ge on the side and eventually 5s-gte
Your idea of 'making the 5s-fe a naturally aspirated beast' using cams first and other things later is a good motion....however the 5s-fe head isn't the best to work with if you're after cam mods as there are no 'off the shelf' cam upgrades for this head...Otherwise you will be looking at an extremely costly upgrade with not that much benefit.
Consider doing a 93 or later 5s block with a 3s-ge head (5s-ge) as there are (I think) two heads that are bolt on, save modifying the coolant channels.
This way you can buy 'off the shelf' cam upgrades which will benefit you in money cost to power gain ratio.

yeah an aftermarket ecu may go in, at the moment obviously I cant take full advantage of this setup as the standard computer is the real choke point, however it's doing a good job just now though. I can boost to 10psi but I wouldn't go past this until I get the springs upgraded and the main bolts, maybe upgrade the rings as well and should then be able to go bit further, to keep things running OK i wouldn't go past 13 or 14 psi. I would have a haltech or similar at this point, my mixtures currently are quite rich but economy/general driving is quite good.

Nah, a good friend of mine did the work but honestly it cost him bout maybe $1000 in materials and he just put in the hard yards of a little custom fab work. I myself didn't have a hand in the build but I've assisted him with other projects and cut him stuff at work, only cause I laser cut steel. This setup now is nearly 2yrs old. Engine is making easily over 200hp, he's had nearly that at the wheels on 10psi.

this is 8.5psi, current boost. That will be changing in the next 2 weeks or so

? a aftermarket ecu will smooth those out some and save me some fuel and give more ponies... few of the guys up here said to put on a rising rate fuel pressure reg will also help a lot before changing the ecu.

wouldn't help having bigger injectors either, but I'm glad it's rich...... ouch to lean afr's
Posted 10 November 2014 - 09:03 PM
Some can see my afr's are a tad rich....mmmmm yeah you're right, more boost needed and as of tonight... more boost

Im not sure, haven't put on the dyno to find out. was running 12.5 psi and was great on a cool night but recently had to wind back the clock as we had a warm 35degree day and she pinged out on the highway and so the knock sensor obviously reached it's limit. sitting on 9psi at the moment, thought I'd play it safe.
Had a reality check about why I bought this car and its just to have that extra shove in the back when I need it.
I think that I won't push things too hard with this car, it fills my purpose....it goes hard without spending a fortune and still gives good fuel economy.

fark thats a clean sleeper. some stock wheels should do it
