2G Engine swap 2.0 to 2.3

[Drewzdude]

So I know this gonna sound dumb but if I go from a 2.0 stock motor to a 2.3 stroker guessing ECU need to be reprogram

Yes. At least you should have a SAFC or some method to adjust fuel. And if you have the stock 450cc injectors, you should have larger injector if you want to boost higher than the stock level. The stock injector would be maxed out soon.

Ok thank u. Ya we're already maxed them out need to tune for the amount of boost were running it burns all the fuel and ECU cuts out cuz past what it can do. But motor took a shit so now gonna do engine swap then back to messing with ECU again.

Now I see you have a 16g, so anyways even with a 2.0, you have to have some method to adjust the fuel at least. If the car is for daily and you are not planning to modify the car more in the future, a SAFC with a wideband O2 sensor and gauge would probably be fine. If you are planning to modify more in the future, I recommend to have a ECMLink or some standalone ECU.

I have a standalone I'm going to go with. I have a fuel to air gauge already and I've tried the maf translator that just caused more problems. . But ya it's not a daily I've done to many mods and for what I want it's a race car. Done bigger fuel pump and everything basically but the motor and the ECU everything else done was. If could do the ECU would already have the bigger injectors in. Also thought maybe a way around messing with fuel but still think the ECU would make it cut is turn up fuel pressure. Idk thou.

Basically I bought all the goodies I just haven't been able to do any tuning and it's budget built so me and buddy trying to learn to do are self. With everything we did got lil shy 100 more hp out of it with out tune I cant imagine how much will get once we have it tuned plus I have a built motor I think it's going to jump up drastically from what we were seeing before from 307 car comes stock 210

That's 210hp measured at the crank. I'm assuming you measured at the wheels. So you're actually doing better than you thought

 

[Drewzdude]

I ussume it's at the crank cuz I'm using VP16 for readings

Ah. I wonder how accurate that is.

If you are planning to make higher number and using the car for racing, I recommend to search first what's the pros and cons of a 2.3L 4g63 stroker, and then plan what parts you would exactly need.

 

[Drewzdude]

I've done some research already. But more wouldn't hurt. I know there not as hi rev but more lower end torque and they say fast spool up. But that's not a problem for me already so not worryed. I here good things about them.
