2.5 Intake swap

[nd4more_spd]

Hey .
i m doing the 2.5 V6 intake swap from Ford Probe to MX-3 , i was wondering if anyone ever did this and if i will need any special modifications like ECU for it ......
-Thanks

I dunno if this really will do much but no you don't need another ecu. You could contact Mikeseli on probetalk and see if he can burn you a chip to open your vris at the correct points. Oh and get Pheno spacers!!! Reuseable gaskets and cooler air to boot.

hey whats vris and Pheno spacers ??? , i rebuilding the engine and changing the left cylinder head, and i asked my mechanic to put in the fuel injector from the probe GT since i had one laying around... he looked at it and said he will try to do this ..., i don't really know if that will help anyhow in HP gains... , what do you guys think ?

Don't use a KL injectors on a K8, they flow at 220 cc's compared to 170-180. You'll be running way too rich.

You'll smell raw fuel and bellow smoke from the exhaust. Your o2 sensors could suffer over time and possibly clog your cat.

I mean , what will actually happen ? , wil the car be driveable ? , will there be much more power ? will it suck much more gas , or the engine wont run smooth ........ ?

cool no

[nd4more_spd]

i mean , it shouldn be worse then probe on gas .... , i donno , is it possible to do something with intake so it would run good , and make more power out of this fuel injector .., or is there any parts on this injector that i could just put on K8 injector so it would be more powerfull.... ?

if you have 1.8 engine use 1.8 injectors. The Probe injectors will just be dumping more fuel than the engine can burn. Running rich robs power and leads to other problems

i am also installin performance intake right now , maybe it will help to run better with this injector?

[Spydie]

It's nice to think so but I doubt it. And I'm sure it's been tried before and failed. That's probably why it's not a popular endevour that everyone else is doing.
Someone else advised you to look into pheno spacers. The full term in intake manifold phenolic thermal spacers. do a search. There's loads of info on them.

So , you think it won't add any horses ? Can't i control the fuel any how ?
ok, what about the throttle body ? is it any bigger on the 2.5 injector ?
i just need help , if you guys think it is a very bad idea and i won't have any pluses from it , i ll just throw an old injector on ....
-Thanks for info...

I tested them on my K8 before going turbocharged, and noticed that I had to run a fuel pressure of 19 psi in order to make it go nearly the same as stock. You must have an adjustable FPR and FP gauge in order to tune it. Adding the intake won´t make any big difference for needing such fuel delivery.
