max'd out potential?

cheers mate.

bit more on topic i would say on a completely stock engine i would say 275bhp is certainly achievable if you have the set up right.

stand alone ecu
fueling
ignition
good manifolds
good boost control
etc the list goes on.


stock injectors are good to 200bhp
and stock ct9 good for between 170-180bhp

What kind of ignition modifications are you making ?

Oh yes, I forgot to mention.. that graph above is running stock ignition. TRD leads, stock (original) coil, ignitor and dizzy.

depends on the set up.
normally consists of..
decent set of ngk plugs, normally run 8 heat range and gap accordingly.
set of external coils with built in ignitors and some 8-10mm leads.

what make of external coils do you find works best, and is the easiest to setup ?

all i would say is pictures would end this debate ,you do sound fairly confident that it can be achieved so if it was me i would be putting up loads of pictures and rubbing it in to all the non -believer's which i think i am also lol

I'm afraid the best I can do is the dyno sheet of its previous tune, assuming 17% drivetrain loss (conservative compared to some figures i've read here) this is 350bhp

IMG_1939.jpg


It went on to make 240wkw or ~380bhp with some changes to ECU and boltons. Both finx and myself have been in and driven this car. I believe the car has since been rebuilt with forged internals and they're talking about 300+wkw or 470+bhp from a 4e.

hey all. im the owner of this car their talking about and i can tell you now that it is all correct information if you want pictures ill be happy to show you all...im not to good on a computer so if you send me your email addys ill post them all to you...

so weres the 380 bhp talk gone now its 275 full of crap talk

ya but THE GRAPH PROVES F**k ALL no why standerd gets 350bhp is there any lads here that build engines to shut these lads up never seen so much dreamers

You're awfully confrontational. I don't particularly care if you believe me, finx or ryan, fact remains his car has a stock bottom end and laid down 380bhp. Ryans setup is pretty extreme and the lag isn't for everybody. Go read the 300whp Jamaican style thread if you still have any doubts about what's possible. It's cool to see a reputable member documenting precisely what's neccessary

i would'nt say it's not possible of making that power on stock internal's, but i would say that i cant see it lasting to long on a track for a 20 mins of boosting, and that the glanza rods are alot thinner than a gt rod,
when i took my first engine apart couple years back all th rods where bent and that was only td04 at 1.6bar (stock bottom end)

from what your saying theres no way it can hanlde 350 plus its been tryed here by a few lads and the engines go bang after a week or so running tops 250/260bhp:homer:

Say what you like, I drove the car a number of times when it was on the tune above. It ran daily like that for months, wasn't exactly going easy on it either. The engine eventually did crack a piston due to inadequate octane fuel after some hard runs at almost 400bhp. Obviously a motor like this isn't going to run forever but save for the fuel issue there's no reason it couldn't have continued for quite some time.
I'm currently uploading quite a few photos of the rest of the car.

Joking aside though, all this makes for interesting reading, would be nice to at least see all the evidence before anyone makes their mind up. Such a question is always going to stir up some controversy so I'm going to sit back, shut up and hopefully learn something.

Oh Ryan, fire whatever you need posted to jaysgarage@hotmail.co.uk and I'll make it happen.

im very proud of ya weres the videos 400bhp now on standerds your away with the fairys:beer:

ok lads not Doubting ur Figures but

1. What Turbo / manifold / wategate setup
2.What Pressures u running?? fuel / boost??
3.What ECU
4. What Fuel rating

if a 4E motor could push 300bhp on low boost then it could be done
but that would mean u would have to Run the correct Turbo to

A. reach ur goal of 300-350bhp
B . Not be way laggy that the E-series engine cant run it.

My question to you is lads :

What Turbo have you been running that can run a Toyota 4E engine over the 300 mark on LOW BOOST???????

Now if i was Running a 4E motor stock i would throw a Triple layer Metal gasket on her and run her with 1.2 bar on a GT2860 and im sure i still wouldnt get 350bhp mark.
Headbolts are not a problem running boost up to 1.8 bar as ive built both stock and Forged engines running serious boost and never had a problem with stock bolts!!
on the other hand STOCK TOYOTA HEAD GASKETS are gone after 1 BAR of boost. not realible and thats proven from experince.
so if u were To stay Stock EVERYTHING ALL PARTS INCLUDING HEADGASKET ANd BOLTS ud be BOOSTINg lets say 1 BAR.
WHAT Turbo is gonna reach 350bhp on a 4E series TOYOTA engine @ 1 bar boost lets say before u hit ur limiter oh at lets say 7500RPM
please let us know ;)

1. What Turbo / manifold / wategate setup

3.What ECU
4. What Fuel rating

1. The dyno graph posted earlier was running a ported STOCK manifold modified with a Subaru flange to suit a VF28 from an STI
2. 21 psi/1.5Bar boost pressure. Stock fuel pressure regulator at stock rail pressure.
3. Stock ecu with an eManage ultimate set up as a piggyback
4. 98 Octane pump fuel

My question to you is lads :

What Turbo have you been running that can run a Toyota 4E engine over the 300 mark on LOW BOOST???????

That really depends on what you define as 'low' boost. There are basic physical constraints, you cannot make huge power with a small turbo on a small motor. Everything is a compromise, however you can optimise each piece of the puzzle.



Headbolts are not a problem running boost up to 1.8 bar as ive built both stock and Forged engines running serious boost and never had a problem with stock bolts!!
on the other hand STOCK TOYOTA HEAD GASKETS are gone after 1 BAR of boost. not realible and thats proven from experince.
so if u were To stay Stock EVERYTHING ALL PARTS INCLUDING HEADGASKET ANd BOLTS ud be BOOSTINg lets say 1 BAR.

Not quite true mate, plenty of people in NZ running stock head gasket at pretty serious power levels. It can cause issues, as can just about everything at these sorts of power levels, but it's by no means the weakest link. They do not consistantly fail above 'x' boost level.


WHAT Turbo is gonna reach 350bhp on a 4E series TOYOTA engine @ 1 bar boost lets say before u hit ur limiter oh at lets say 7500RPM
please let us know ;)

None :) Never said you could do 350bhp on 1bar.
