My Setup:

Engine B16A2 (160HP stock)
KKK K26 turbo (sized as T3/T4)
Tial 38mm WG spring 5psi
GSR pistons
Commetic head gasket 0.30 thickness
Eagle con rods
custom made log stye manifold
big FMIC
greddy type S bow
walboro 255h fuel pump
precision 450 injectors
GSR Cams
race clutch
oil cooler
profec b spec II
all new bearings and rings
custom manderel bent piping 2 3/8
custom made exhaust 2,5
uberdata tuned
obd2>obd1 conversion


I'm new at this board.Everytime I read this huge forum I start do doubt in many things.Project with my car is going for months. I notice many GSRs with over 400BHP using stock internals. Should I believe this? Whats the limit you think I can reach with all my modds on my car? I wonder how "strong" are the GSR pistons since they are not forged like other turbo pistons. (CR will be approx 8.5:1 in the end) Let me remind you that the engine is in good contition, with all bearings changed. Whats the boost you recomend me to deal with? How much boost will make how much power according to this setup exactly? Dont forget that Im using stock transmision and axles.

Thank you in advance for your replies!

Here are some pics of my setup.All items are brand new

K26 turbo





front

 

I LEIK, looks like the stock airbox and windshield fluid resorvior will be moved/relocated...due to the i/c piping. Otherwise nice setup..post some #'s...

 

This is an old pics, don't concentrate on such details, the photo was taken while I was testing the FMIC and Oil cooler fitting.I will post some fresh pics asap.

The first thing you have to realize is that with a competent tuner your set-up will rock. My only question is... What HP/TQ are you shooting for? Because with those injectors you'll be limited to 300 to 350 max. GSR pistons are fine unless you run too rich/lean. If you want more HP/TQ than that i'd suggest some sleeves But your mantra should be "tuning tuning tuning", thats the right way (and only way) to great HP/TQ numbers

 

My question is, why did you stick with non forged pistons if you already decided to change the comp ratio by going internal? Sure cars can run big numbers with stock parts, but for how long. With strength comes reliability and repeatability. But judging by your parts, this setup will not come close to making 400hp, maybe in the 240-270 area. You are limited by your injector size and comp ratio. 8.5 to 1 comp in a B16 is not the best of choices. Its gonna be very lazy on the street. Your setup with 9.5 -10 to 1 comp would be better suited.

 

That turbine looks T4 based to me... not T3... that's quite large!

 

Becuse I'm from Europe and there are not's so many tuners who will make me resleve.This is my first project car and first custom made in our country, next year I'll replace my pistons with forged.
For how much are good these injectors?
Are we talking about WHP numbers?
And one mistake my CR will be 9:1, not 8:5

 

T4 is bigger, this turbo looks like T3/T4.Also K26 blitz uses in their kits for b16.

Some other pics..

 

METRIC! lol

 

We use metric system here in europe

Mikes: I saw many peope who made over 300whp with their 440' s.

hehe yea i was like HOLY 5inch exhaust side batman!! But then i was like..wait...metric at 5cm is almost 2inchs. thats better.

Hi guys!

Im also a freshman here, after years of reading, I had do register :-) since Im a friend of the owner of this project and we are building this "rocket" together. So Im gonna put some extra quesstions to squeeze as much infos I can before this devil will be put on the street.

1. For the pistons, they were bought cause it was a cheap oportunity, I bet on the CR that they will handle such power, my predict would it be approx 320HP on the cranck safe for a drag. what do you say on this?

2. Injectors, lets compare a bit, Greddy Si kit provides 320cc injectors and they can handle up to 300HP on the cranck. So I dont think that 450 ones will be the limiter of the upper power.

3. C/R: According to the size of the turbine I think that it will spin very quickly, 3000rpms+. Can you define the word "lazy"? Do you mean lazy in lowrange, midrange?

4. What about LSD? Should we take one? The car will stay on street tires, sized 205/45 R16.

Take care fellows, looking forward for your help!

 

Forgot something

What about MAP sensor? Does it handle over 0.6 bars? Or should we swich it with other one, which one do you reccomend? Lets say a map sensor found in other car so it will be easy to buy.

bye.

 

Yes thats true. Alot of people have done it. But the thing you gotta realize is the injector is maxed out. Its not good to have a injector running at 90-100% duty cycle. It taxing your injectors life big time. Get a set of 550cc injectors and have room to spare. That will also bring your duty cycle down to about 70% which is nowhere near maxed out.

 

Lets consider a CR of 9:1, and boost 1.0bar drag setup and 0.5 street setup. Would it hurt the injectors?

bigger injectors will be installed after a while. Now its the job to make the devil work :-)

PS: it will be a street car 95% of the time, only few drags will be driven anualy.

 

people make the 300hp with a rising rate pressure regulator (fmu). this is what allows them to get more out of their injectors. injectors are usually tested at around ~43psi in the fuel system. If you up the psi of fuel, you can get more out of ypour injectors. On a side note, this topic has been covered in many threads on H-T, Look around and Good luck

 

What do you think is the safety area with my setup?What's my max whp goal for this setup..I would really like to know, where is the risky level of my setup.I'll use high boost only for drag events..Thanx for answers..

LOL

jure, don't confuse these guys with our system

twin-cam: you as an expert should know that the stock map sensor reads up to 1 bar of pressure if not 1.2 bar. so no need for another sensor.
