I want more than 350hp on Stage3 please :)

[GreeceS13]

My setup...
GT28R 20psi, xs manifold + elbow and a 3" full exhaust, 444 inj, z32 maf, huge apex fmic, induction apexi!

350hp crank and 307whp! Torque not very good... 380NM!



I am looking for GT28RS .86 A/R and I need help...!!!!
First of all how much boost can I run in stock ca18det motor with gt28rs?
I need something like forged pistons or gasket to run a gt28rs at it boost limits?

444 injectors can feed quite rich the gt28rs at it boost limits?
If not how much boost levels can feed quitε rich the 444injectors?

Is it a good idea to put KA24DE throotle body or I will have problems?? Some people loose a little power with this mod

[spesh]

Skip the RS and get a 2871 imo (and i've got an RS)

You'd need to change the injectors also, they cannot supply enough fuel for an RS.. mine hit 12.8(ish) afr on full chat at 20psi which is a little on the lean side of life really

[GreeceS13]

I sure want to have 11.xx afr! Now I have with this setup 11.0!

20psi with jez stage 3 and stock fuel pressure?
Why you don't try to run a little more fuel pressure?

If I put 2871R I will sure need pistons.. maybe and rods..!
I want some more horses without many money!!



Also I run with BCPR7ES... is it ok or I need 8es? Also I use 0.8gap!

Firstly, there's no way in the world you have that power with that setup, especially in a hot climate. Either your dyno is very incorrect, or you dont have the turbo you think you do. I've not seen a genuine 300bhp on a gt28r yet.

Secondly, I would go for a 2871r

Thirdly, if you want more power, its not stage tuning anymore, get out of the stages mindset. Get yourself some 510cc or 560cc Mitsubishi EVO injectors and look at custom mapping

Agreed

I've not seen a genuine 300bhp on a gt28r yet.

I've done 320bhp at SRR
With octane booster and fast ramp rate on the rollers, pushing my luck

Secondly, I would go for a 2871r

Me too

Yarp.

One of madda's old cars made over 300 on a 28r

thats why i was careful to say i'd not seen it

[GreeceS13]

Guys this is the power of the motor...!
As you don't believe it I didn't believe it too!
I make more than 7 runs on the dyno!
You said here that gt28r cannot run more than 17psi!! Ok at 17psi I saw 320hp (crank)! There are many ca here with this boost and with this power!
I try moreeeee boost and I saw 350!!!

Ok the dyno had problem? Ok! The best dyno is the street!!
My car is faster than other cars with more power and lighter..!
My last was a corrola '02 with 3SGTE with 327 wheel hp and it is lighter ofcourse...! My car was faster!!!
All greek dynos sucks?? :P

Anyway I would be happy to see 380-390 in the same dyno that I saw 350 :P


======================================


You suggest me 2871R... Ok!
But you didn't say me what I will do with pistons... headgasket.. etc!

If I choose 2871R I will need at least big injectors and remap!
What else?

But tell me please what I will need to run at limits an RS!
Noway I can fead it with 444injectors?
Also I will need pistons or headhasket or something else?

I also like 2871 but I don't have enought money to complete the necessary setup and I don't know if it is worth...! Maybe then I will need more parts like clutch!! With 2871 we can go up to 450 but I cannot do it... maybe in some years lol!

please correct me but i believe that you increase the fuel pressure enough you will e able to supply the needed fuel, but increasing fuel pressure, may result in other problems. and you will also have to maintain that hi fuel pressure and a hi flow rate... (adjustable fpr + fuel pump may be needed and with the price of that maybe you could upgrade the injectors....)

[GreeceS13]

I have fuel pump walbro 255l/h!
If I put larger injectors I will need also remap :P This is the big problem!

What other problems I will have if I increase the fuel pressure with an adjustable fpr (i can find one for a friend)??

[Fake Ben Taylor]

sorry - i meant to reply to your pm but was busy

pretty much agree with whats already been said

[Vetal]

GreeceS13, no offence, but I'm sure stock S13 will put 200HP on those dyno I agree that it's not possible with that turbo and those injectors at those AFRs. What's your exit speed at 1/4?

[slider91]

I would go for a 2871r as I have and I am getting 304 bhp and 295 ftlbs of torque on stage 2 admittedly she dets like a mofo as I am using standard ints and injectors ect

[Madda]

and the thread is still kicking about. I miss that rad and ic Anyone know where the car is now?!

I don't think so.... with gt28r there isn't any car in Greece that make more than 320hp
All people in Greece they don't believe that the turbo is a GT28R!!
I have many fotos when I put the turbo and it is sure a GT28R!

Anyway my exit speed isn't good because my gearbox sucks and I couldn't put the 4th gear no way... I finished the races with neutral.. also I have slicks tires so slower exit speed... anyway 105 mph!

[Vetal]

Then couldn't really compare... Mine is ~108mph at ~300hp

[Dave]

Forgive my nubishness, but isn't the 52 trim 2871R the same turbo and/or power output as the HKS GT-RS?

Yep.

[Robdriftit]

350bhp on a standard engine? shorley that wont last very long? thought the rods were only good to 370 and the rest not as much?

over 400 has been seen on a completely standard engine, and it was the rods that failed then.
