7afe turbo numbers Options

[SilvertopST]

Im toying around with the idea of boosting the 7afe instead of swapping it since the motor only has 60k miles on it and was wondering how many psi those who are running the 7afte are running and the horsepower/torque numbers they are running.

From what I've seen on the boards and heard from looking into this a bit myself, 8psi is an optimal range for the 7A. Much higher and I think things start to, uh, "spring".

it all depends on what your setup is

[SilvertopST]

if i do this id run the following:

t3/t4 or t25 turbo
2.5-3" downpipe with matching cat back exhaust
FMIC
Blow off valve
315cc or 350cc injectors
Air/Fuel management system (greddy emanage or SAFC)
3sgte map sensor
and whatever else i may be missing

never really understood the reason people change map sensors?


it will hold at 8psi

just in case u go over that psi is y u need the map,ur missing ir intercooler system,fuel pump,exhaust manifold.most 7aftes will hit 170-210hp

thanks for the info, i had a list of all the nescescary parts but was too lazy to pull it up when i was writing it.

since my motor only has 60k miles i have been debating on turboing it or swapping in the 4A-GE silvertop. but it looks like for about the same price as the swap i can get more power and not go through the hassle of swapping the motor.

Very good decision. No sense letting a good, low mileage engine go to waste.

^^

I figure, i can run this motor for a while then when it gets up there in miles do the swap and use the parts i have to boost the silvertop

Just to let you know. Just because you have 60k miles doesnt mean your motor is in tip top shape. A motor with 60k miles driven by a younger male, hitting the rev limiter all the time is different frim a motor with 60k miles driven by an old woman. Make sure you do a compresssion test.

[SilvertopST]

itwas actually driven by my grandma only like 2 days a week, but i will still be doing a compression test.

lol bccentaur3 u got served lol,ya then u gotta think about gas prices for a turbo,and wat you would do if u blow ur engine,u should upgrade ur clutch also if ur planning on this..The search key is a messiah for u right now,there are i think 4 detailed build thread for 7aftes..ill pm u the links if ya want.

wrong the new map sensor lets you engine read boost if you dont change this you will at least have to use check valves

[southwest2118]

and if you don't do neither?

boom boom

[southwest2118]

i've been running boost with no problems?

[CelicaST_CALI]

the engine would run much better with it,right now the engine doesnt know it has a turbo

[jesterwr217]

ask nuke manny or nik they will all tell you the same thing

[southwest2118]

observing my wide band its exactly where i want it.... which is 10-11 at boost and 14 else where...what difference would the 2bar make? would it be a more precise incline to 11 from 14? and what are all the engines i can take this from?

[CelicaST_CALI]

ur running 11 psi ??
