Thanks for all the replys guys as for the head work on the valves what besides 3 angle valve job could I do?
Does anyone know how much boost the Garrett T25 turbo with a wastegate can get?

im looking at that very same turbo man >tongue.gif> i been reading and it said the turbos good all the way to 300hp. but at safe boost (6PSI) u should get a good 30%-50% increase in hp depending on the setup. so with an ST... prolly what.... 130-150hp? build ur internals a bit and u can go higher boost. also said the turbo can handle 15PSI no prob. im giving this turbo (turbo kit) a good thinking myself minus the internals work since im looooow milage. also... look at the garret T25BB turbo. same turbo but its dual ball bearing, suppose to reduce lag and add more power. i know some members here got the T25 so if u guys can.. enlighten us on how this turbo handles >biggrin.gif>

..(formerly daily driven) 3S-GTE powered celica currently set @ 12psi..
this is IMAO but i think just the T3 bottom trim is just fine for 7afte set not really any lag and can put out 250 horse (on the turbo)

but you guys need to look and the maps to see where your goals are and the efficency (sp) of the turbo in that range

a turbo 7afte is a fun car not the fastest and a quick car

yea your 3sgte is cool but ill stick to my 7agte
i suggest a t3/t04 its a great turbo IMO
gets minimal lag and a great topend pull
just an improved T3 lol

but t25?
comes in most "bolt on" kits

not my cup of tea for that turbo
t3 is best bet

i disagree i think the t3t4 would lag more and kick in later in the rpm band

yah i hear ya guys... the T3 is probably a better turbo. but i cant seem to find any turbo KITS with the T3 for the 7afe (i say 7afe cuz im looking/thinking into buying a corolla 7afe turbo kit... since theres prolly no turbo kits made for our cars anyway). the question is how good/reliable IS the T25? since there is a kit made already with this turbo for the 7afe. not to get off topic but where would the best place to buy a turbo kit be? im looking into the kit since i dont plan on running high boost anyway.. just reliably safe boost

..(formerly daily driven) 3S-GTE powered celica currently set @ 12psi..
anywhere with a corrolla kit i guess

nah the T3/T04 to my understanding was made to reduce lag with the ability to extend the top end as well?
but then again i could be wrong lol kwanza?

Zipstrips used a T3To4b and swaped to a T3 because the lag... I'm pretty sure that's how it was at least.. it was a while back.
How much boost is the T3 or T3/T04 capable of?
Yeah that is the hp but im talkin about how much psi of boost can you get out of it before the turbo will get damaged 15, 20???
the t3 and t3/t04 can both handle that HP
your engine will most likely blow b4 that turbo haha

but you can't hit that (300-350hp) mark with a 7afte
flat out just can't be done?
don't think the block itself can handle 300
if it can your pushing the limit of the block
at that point just better to go 3sgte

even though i'm pro 7afte and keeping "original motor" pride!

You're just guessing again... >rolleyes.gif>

Iron blocks are really the strongest they come... The only major issue I would see trying to push 300+ hp is the rods, pistons, and the fuel... but seriously now... what's the point of talking about it?

All talk about the hp but none about the psi capability?
the HP talk is related to PSI or vice versa

if you have stock hp its
how much boost does it take to get to the max hp level

when the rods, crank, pistons, and such crap out
so you find ruffly how much boost it takes to get to HP
Yeah I realize that but if you buy a turbo that can only create 15 psi then your not goin to be able to achieve as much power so I am just wondering if there is any boost limit to the turbos that have been discussed.
ok say i buy a 7afe fro ma junk yard, build up internals and all that turbo it when all said and done pushing 250hp and some og psi(not good with turbo lingo) anyways if i wanted to switch to a 7atge whould i have to buy all new internals and everyhting or just the head
hrrm a boost limit for the t3 or t3/t04
i don't think is an issue with our cars

both turbos should be able to boost 15-20 psi

go to www.turbocalculator.com and check that sitte out

you would need pistons 4ag to match the head
plus the head intake manifold new exhaust manifold
you will want to use the 4ag wiring harness or a stand alone
belt from 924
and a bunch of little things
