Turbo psi/hp ratio, 5sfte questions Options

[urbandork]

First off let me say i have searched and gathered lots of info but i still have some questions as sometimes the truth was confusing.

First off what’s the highest psi I can run on a stock 5sfe. My engine has been rebuilt to an extent. Rings and a new crank as well as other tide bits. Would i need to build up my engine even for lower end psi numbers and if so what would i need to beef up?

What HP numbers would I be looking at if i run 5psi 8psi and so on?

The car would be a daily driver what would be a good boost and what would i get hp wise.

i have figured that with a N/A set up with CAI header and exhaust id be getting maybe 20 more hp so around 150. (CA stock is 130). I’ve been wondering if its worth the trouble to go turbo or if i should just stick with N/A.

thanks in advanced

I surely dont think just a cai header and exhaust will give u 20hp.

[urbandork]

lol well tahts beside the point perhaps its more like 15 ish.

My real questions are about the turbo and what hp ill be looking at when running certain psi and also what might need to be changed to beef up the engine if needed at higer psi.

lol well tahts beside the point perhaps its more like 15 ish.

dude..i don't think so. maybe like 5-7hp, 10 max.

Just get nitrous. I feel it's a better choice over boost. I'm actually buying another nitrous kit

[urbandork]

lol ok besides the point of the NA stuff im mainly intrested in the Turbo specx.

Please no more about the NA i get the point. Infact now i want to Turbo as i can see that going NA will not get me a good HP to cash ratio.

I have found what ive been looking for for the hp and psi stuff but now my question is about if i can run boost on a stock 5sfe and if so what are my limits.

yeah, and dude, honestly, that must have been one crappy search, if you can't find our speculative max boost limits for the 5sfte. Our guesses in the past have ranged from 8-11 psi. for daily driving

[urbandork]

no no i got that far but i would assume that there are internals that probably need to be changed. I didnt get any of that from the sticky.

Or is it that a stock 5sfe can take boost with little worry.

It seems like all you got to do is slap on the turbo stuff some stuff for fuel delever and start boosting.

Would THIS be a good turbo to get?

IMO any straight T3 with under a 60trim compressor wheel is gonna get choked at higher RPM by the 5s..
urban..its hard to give rock solid #s, cause everyones setups vary so much...i'd say most guys run somewhere between 7-12lbs...as far as HP #'s...there isnt may guys here with dyno time...so its hard to say...id guess the basic setup is good for around 160-200hp depending on boost level.

First off, you cant have 2 first offs, ones gotta be a second off.

Then - safe psi varies. Depends on supporting mods, cooling, exhaust, compression of each individual cylinder, wear and tear on the engine. Theres no standard for these things because so many diffferent things can cause problems. If I were to guess at a safe psi, I'd get <6psi. 20hp with cai head and exhaust is very liberal, your looking at 8 or so. Remember we dont drive highly restrictive hondas, parts like these dont do the same as they do to hondas.

A T3 has more than enough flow for a 2.2L - 3sgte people upgrade to T3 so its not going to get choked or anything, especially a 60 trim and the levels of boost your going to be running.

The biggest killer of engines is detonation, so get a good intercooler and sufficient fuel system. You'd look at a 50-70hp increase, depending on what else you have and what pressure you run.

[presure2]

super..ive never seen a 3s with a STRAIGHT t3 on it...have you ever ploted over a T3 compressor map? @ 8psi even with a 60trim...your off the map by 5000rpm..not where you wanna be...now a T3/4...thats alot more common..and a better choice for the 3s..or the 5s for that matter..

[Supersprynt]

Mroe common but he's gotta 5s, a bigger turbo means he needs bigger everything else. IDK if he's in for that.

[shid]

but super, what pressure and I are saying is that the T3 is a little small for a 3sgte, and more than a bit small for the 5sfe- unless you get a huge one (which they make... which I find weird)

[Supersprynt]

Yeh it'll be a lil small for the top end but buttom he'll have some nice torque figures.

Its not tooo small its just, a "meh" upgrade. (For the 3sgte) I forgot he had a 2.2L...I still think the T3 will be ok, I mean yeah its not big but ppl are putting on stock CT26's with decent figures so T3 isnt going to totally suck.

Yeah, I think after Itchy gets over the spool up time- compared to his old supra CT26 (jesus christo) he won't be happy with it as an upgrade. I think he might lose some top end too- I believe the CT26s on the supras were huge.

[Supersprynt]

I was under the impression the Supra CT26 is just the same except larger exhaust housing which isnt bolt on to the 3sgte.

[urbandork]

do you guys think i should go with a ct26 twin entry or a T3.

If i go with teh ct26 ill just get that shinny header for the 3sgte but if its the t3 then ill get that ebay manifold with the rebuilt Garrett T3.

Im looking for a good balance of spool time, topend and lowend hp as well torque. Itll be a daily driver (street LA freeway traffic) so i want to have some torque when the light turns green but dont want to miss out on the boost later on down the line.

[shid]

Super, I don't know the specifics, but they're PIGS; Itchy's doesn't spool til 4k
