Default 11@1 piston VS Turbo?

One of my frend did have destroy is 2000 RS with a full done engine, how is ok. With:

11@1 forged piston
Eagle rod
Spicy Cobb cams
Over size TB
Cobb Ported head
Link stand alone

And he want to sell it for the 1/4 of what it wort.

I allready have:
STOCK ENGINE
Lachute 3/2,5 Turbo/Back Exhaust
Borla Headers Gen4
Halley Fuel Pump (650 hp)
Cobb Tuning Cams
HKS Super Mega Flow Air Filter
HKS Intack
Go Fast Bits Blow Of Valves
ASR Up-Pipe 2.25''
Julien Performance Down-Pipe 3''
Costum water foger
Costum WRX Intercooler
Turbonetics MBC (set a 9psi)
Turbonetics (T3/T4 Garette) Turbo
B&N Oil Engine Cooler
Unorthodox Racing Full Pulley Kit
420cc WRX injector

VDO Oil Presure Gauge
VDO EGT Gauge
VDO Boost Gauge
Extreme VDO Tack
APEX'i S-AFC
Split Second TMC1 timing controler

I do asking my self if i can take is engine and install my turbo setup??? It will give me a tons of torck at low RPM and alot of snap right of the box . And becose it is forged I will be able to install some NOS (50 to 75hp)

Do you think i can run a 9 to 12 psi of boost on a 11@1forged pistons with NOS???

What do you think of my Idea???

Sure, at 9/12psi, with 11:1, I think it'll last...........about 4 to 5 runs.

that is such a good idea!

I think im gonna pull out my 8:1 pistons, throw in some 13:1 pistons and crank the boots up to about 25 psi.

And if the engine doesnt blow up in 4 seconds, I always got that engine self destruct button, that I call NOS.
[/scarcasm]

I dont know how people manage to turbocharge thier car, then come back w/ a question like this

Answer --> They take it to a shop like Lachute's (nothing wrong with them) and say "Make it go fast, here is my money".

If I threw all political correctness out the window, I'd say you'll blow that motor all the way back to the country you came from.


Being nice, I'd say don't do it. The motor was not built to see boost of any kind. Research forced induction in general and you'll find out why.

All that stuff would be great, but get a different compression piston, if you used the 11:1 the rusults will be.

turbo: 1
11:1 piston: 0

Turbo wins, and your motor is blown. if you're doing internals anyways, get a compression ratio suitable to turbo and sell the 11:1 to one of the N/A guys.

If it was tuned right, and if it had very good head gaskets, and if it had proper engine management, and if it had proper fueling, and if you ran proper octane fuel (read: above 100 octane, all the time), you could get it to run at 9-12psi.

You would have to run VERY low timing or VERY high octane fuel (or both), just in order to keep it from blowing up.

Then you have to worry about the cams... being spicy cams, they are no good for turbo use as they have a lot more overlap then is ideal for forced induction.

Basically, you'd have a car that ran like crap that you'd have to limp around or take out a loan just to buy fuel for.

Hmmm... This is all I read in between the lines...

IF THIS

IF you could really get everything to work PERFECTLY, IF may work.

However, we all know the odds of getting all of our wishes to IF WORK together.

Just like the same odds of getting CRAPPED Upon by an alien emptying the holding tanks from his UFO.

- IF its a BLUE color.... well... Its from a plane... call your local FAA office.

- Still wanting a reliable supercharger for the 2.5 N/A motor...

- And yes 8complex is right....

why you guys gotta be mean? you can run 11:1 and 9 psi, you need some crazy intercooling and some insane timing retard too. and 1bazillion octane. and like a 10 heat range plug. IC

I hope you are kidding....

that thing didn't survive very long at all. They are also able to get away with it because the cylinder/combustion chamber design is radically different from the EJ motors... hondas can get away with this too.... but for the love of god please don't subject an EJ motor of any kind to this abuse.
