injector and fuel pump question

[92Inspire]

im planning on doing a dsm turbo setup in the futur wanted to know with the 450 injectors, do i need a higher lph fuel pump and fuel pressure regulator or will the stock ones work and does the ecu or map need any mod on top of that. thanks

You should get an upgraded fuel pump, yes. Regulator, no.

As for the ECU, that is quite possibly the most important thing. You MUST have the ECU properly tuned, or you risk blowing your motor up. (the next most important thing is to use a properly sized turbo... a t25 or 14b is too small)

how do you mean too small. i have 275k on this motor 14b is plenty big at 8-10 psi, i think thats plenty. where can i get my ecu tuned for a decent price, no 350 for hondata, this is a basic setup and shouldnt be that colplicated.

14b is small for the mitsu 2.0's that they power.

look into chipped ecu's via crome

Pressure is not totally relevant to power.
X psi will result differently on all turbos.
A 14B is actually fairly inefficient for the F22, not to mention the instant boost making town driving annoying.

Eg, 10 psi on a 14B = hot air, low flow.
10psi on Big 16G = Cooler air, higher flow.

Cooler air = More dense air = more power.
Higher flow = more air volume = more power.

Small turbo = increased heat. Increased heat leads to engine damage.
The amount of boost you want to run is meaningless. That little snail is small for a 2.0L, and you're putting it on a 2.2L. Run that for any amount of time, and you're blowtorching your internals. I'm not even taking your power production into account... I couldn't care less. I'd rather not see you blow up your motor, though.


It is a basic (as in slapped together) setup, so to be quite honest, it's MORE complicated. You have to know what you're doing to make it work successfully.

Look around locally for a good dyno tuner. You're not going to get your ECU tuned on the internet.

i understand what u guys are saying. but any turbo on a factory non boosted car should be good. unless im using a td04, which is only good for my lawnmower or a weed eater. ive seen many people boost without an ecu tune. check valves and missing links are used for this purpose. i know its not the best way to go but it will work. and boost pressure does matter when ur trying not to blow ur motor. 8 psi on a stock bottom end from a t25 should be just fine.

This statement says it all. It's fairly obvious that you don't understand.

Whats the point in going such a cheap route, which is more likely to result in a blown engine?
You could put smaller injectors in and it would still work, but that would just be stupid wouldn't it?
Boost psi is still irelevant, you need to look at compressor maps and you'll realize why.
A t25 is too small for the F22. As Deev said - small turbos make heat and heat kills engines.

Btw how are you planning on adjusting the timing, and setting your afr's.
