3sgte 4th generation (caldina GT-T) Modifications to 300whp?

[st.celica]

I was wondering what are the ideal modifications for a 4th gen 3sgte to achieve 300whp?

here are some of my assumptions:

*will a 560cc denso fuel injector will help along with venom fuel rails?
( what is the stock configuration of fuel injector of 3sgte 4th gen?)

*Aluminum radiators (from celica st215)

*V type FMIC

*NGK iridiums

and anything else for those experienced 3sgte 4th gen users?

300whp on the stock turbo?
Not gonna happen.

Injectors are also too small. On the safe side you'll need a minimum of 600cc.
Possibly even 700cc. You can still use the stock fuel rail.

Standard radiator is pretty good, no need to upgrade it, unless you want the bling.

[st.celica]

aww. that's sad to hear. . hmm

600cc -> 700 fuel ratio will it only get more richer?

[privatealpha]

Richer fuel ratio is vague.
Like you want the car to run rich on cranking, and under boost.
Come to think of it, you can definitely get away with 560cc injectors.
But it depends on the tune.

Which reminds me dont forget to add an aftermarket ecu and tune, that alone is going to set you back close if not over $2000AUS

[st.celica]

regarding aftermarket ecu, piggyback/e-manage is one potential, if only there will be a hydra-nemesis ecu for 4th gen 3sgte.

Rods could be a problem too.
They are weaker than the gen2 & 3 rods.

Stock injectors are 540cc so upgrading to 560cc would be a complete waste of money you'd be wanting to go 800cc to make it a worth while upgrade.

300awhp is probably above the limit of the standard manifold and turbo. So factor in bigger turbo, manifold, dump pipe, exhuast etc. You may need more then just injectors, ie bigger fuel pump. Then you'll need either a piggy back or aftermarket ecu to tune the setup as well.

i think 540's will be fine for 300rwhp, as to wether you'll be able to get 300 with the stock turbo.....


how does the 4th gen turbo compare to the gen3 "ct20b" turbo? i've seen some push 300 on them but i wouldn't recommened it being pushed that hard on a regular basis.

did the 4th gen tuyrbo;s have ceramic wheels as well? or are they steel like the WRC st205's?

300 whp.

turbo wont push that much. So you really need a upgrade like a garrett disco potato, of course will need an aftermarket manifold too.

rods might last...or they might not

injectors will be big enough, fuel rail is fine. Pump might need upgrading though, and maybe regulator.

you will need a front mount intercooler, 3" exhaust, aftermarket ecu

[st.celica]

all noted..

255lph walbro pump will be enough?

[st.celica]

800cc with stock fuel rails?

[Mole]

No comment on the rest, but don't get any Venom products, heard nothing but bad about them.

If you don't want to spring for a new turbo, you could look into high-flowing your current one.

[st.celica]

like 4-1 headers? whats the ideal configuration(4-1;4-2-1) headers for stock turbo?

[Cuts]

4-1

255 walbro will be fine

[st.celica]

and regarding front mount intercoolers, will it be ideal to have a core size of 600*300*76MM &
3" inlet/outlet diameter?

or a water to air IC w/c has 260*115*110MM &
3" inlet/outlet diameter?

applications for a stock turbo.
