400 BHP 3S-GE project

[Salman_vista]

hello guys ... i am about to start a project for my car toyota vista(JDM) [camry]...it came with a 3S-FE engine but i recently changed it to 3SGE.

I do have a plan to make it 400+ bhp. So i need some help with this project.

I am posting some of picture of my car and a list of aftermarket parts i have decided to buy.

thanx

List of my aftermarket parts

1~86.5mm piston[cp piston]
2~GT3076 Turbo with T25 flenge[35 psi]
3~Intercooler
4~550 cc injector
5~Emanage ultimate.
6~T25 flenge manifold
7~constant fuel pressure
8~boost controller

So guys what you think ? is it enough for 400 bhp? plz suggest me.

thank

what compression are your pistons?

i think you will need more injector

a real stanalone ecu would probably be a better choice over a piggy back system

you also might want to get a 3sgte center feed intake manifold, i havent heard how the ge manifold flows with boost.
good luck

thank you for your reply. i m new at modification so please let me know the best idea to go through this project.

compression ratio would be 8:1

so you think i need more then 550 cc injector?

and do i need to change intake manifold as well?

[Ghostyman]

You're looking for 400 bhp... so about 350rwhp... the 3076 can get to over 500whp so that's not a problem. Good luck doing it with 550cc injectors though.

And constant fuel pressure? I hope you meant 1:1 rising fuel pressure (ie. +1 psi boost = +1 psi fuel pressure).

I don't know much about 3SGEs off the top of my head so I don't know what the compression ratio is. Just out of curiosity, why aren't you starting with a 3SGTE engine?

What other mods do you have planned? You might need to do a bit more planning on this one.

I seem to recall that the 3SGE side-feed is better than the 3SGTE. Also it makes it much easier if you end up doing a trunk-mounted intercooler.

What octane gas are you planning on running?

thank you ghost man for your reply.

i think constant fuel pressure is a device what makes a constant pressure in ur fuel rail..not sure though.

the engine is stock now planing to spand £2000 to build this about 500bhp car...as i said i am new so not sure what sould i do. i have give a list already.

you can suggest me to go for other stuff what i need dui to this project.

thank u

[Salman_vista]

i also thought about that ..getting a 3SGTE engine block but really could not get any...i think 3SG series use the same engine block...just some internal different...correct me if i am wrong.

i am running on 92 grade octane

i have already selected a front mounted intercooler for this turbo....

here is picture of that i have planed to buy..if i found nothing wrong...then i will get it.

[Ghostyman]

3SGE and 3SGTE are almost the same engine except for the turbo and some differences in the head. Like I said before, I'm not very familiar with the 3SGE in particular but most of the stuff I know for the 3SGTE should carry over.

For the fuel, you want it to be a rising fuel pressure regulator. You want an extra pound of fuel pressure for each pound of boost you're running.

You will probably need to get some more anti-detonation measures. I recommend either water or methanol injection. This should allow you to run the amount of boost required to make 350rwhp on pump gas.

550s can just get you to 350rwhp but you'll be running them at high duty cycle unless you have a supplementary fuel like methanol. You might want 800s to be on the safe side.

That intercooler should work fine as long as you do a good job of plumbing it in.

thank yout for your reply. Could your please explain a bit more about facts dat marks up in ur quote?

i am not really familliar with this terms as i am new at modification.

thank you

here is pic of turbo that i decided to buy.

[Salman_vista]

hello guys i am quite confused about ECU...if i get a Greedy emanage then will it able to control boost or giving 7500 rpm redline?...if not then where i can get a after market ECU what is capable with 3S-GE engine... i will be very happy and glad if u guys help me out!!

and about water injector. i dont have enough idea about it... what perticular settings i need for to get water or mithanol injector?

another question to you guys do i need to change my stock valve and spring if i want that much power from that engine?

please help me guys

Water injection is a whole nother system that has to be added in. reservoir, water lines, controller, pump, etc.

If you plan on using Cams bigger than 268 or reving past stock redline, it's a good idea to upgrade the valve springs.

That is a pretty small budget to reach 500bhp (which is a significant jump from the 400bhp you mentioned earlier). At that price, you will definitely have to do all the work yourself. And, no offense meant, I'm not sure you're ready for a complete engine build. Even if you do all the work yourself, it will be hard to achieve a reliable 500bhp from a stock 3SGE.

I suggest you reevaluate your goals and budget. Do you have a specific reason you are looking for 500bhp other than it's a nice number?

[MR2Jedi]

Good point(s) Ghosty.
Not sure what the conversion is from US dollars to pounds(and I know 1 pound is more than 1 US dollar), but i would think it would cost triple what you're wanting to spend to hit a 500hp. Let alone reliably.

[Ghostyman]

£2000 is a little less than $3000 USD. Not enough to do the build correctly. Heck, most good EMS systems will eat up half that before you even talk about tuning costs.

Let's pretend the EMS and tuning aren't factors. What would we have to do? I'm even going to ignore the fact that you have a 3SGE and we'll pretend we have a 3SGTE to work with. Here's the minimum you'll have to upgrade:

- Upgrade the fuel system: pump, fuel rail, injectors, adjustable pressure regulator, various lines and fittings

- Get a bigger turbo, exhaust manifold, downpipe and attach it to your exhaust system

- Intercooler and water or methanol injection

- Camshafts (264s probably) and adjustable cam gears

- You can skip most of the head work. If anything, get upgraded springs and 1mm oversize valves.

- Clutch needs to be replaced to handle higher power levels.

- Ignition system is fine and can be left untouched.

- Cooling system is also fine.

And once again, you aren't going to do it with a 3SGE. Get a GTE head somewhere at the very least.

The more I think about it, the less likely it appears. You should put those 2000 pounds into a 3SGTE and drive it around with basic bolt-on modifications for a while. If you're asking some of these questions, you shouldn't be trying to build a very high power engine. Start smaller and work your way up.
