injectors.will they work?

[dodgetech81]

i have injectors from a 05 srt4 neon stock and also 750's does anyone know if they will fit the msp and run correctly?

 

[JCell]

the biggest ones that fit are the wrx 440s

 

[MSP2024]

yeah the wrx 440's are the only ones that drop in

 

[dodgetech81]

the wrx 440's are they safe to run with the following.. turbolife fmic/GHL tbe/steedspeed mani/aem wideband/piggy back ecu?or for that matter to run on a stock msp

 

[JCell]

they need to be tuned... which if u have a piggy back u should be able to

i dont have the piggy back yet,ill be purchasing it after i buy the GHL exhaust so prob in a week or 2 .just curious because i think i may have 440's laying around at the shop.i figured you would need a tune but im new to msp so it doesnt hurt to ask people who have some experiance with them.i plan on installing the fmic,mani,wideband,tbe,piggy back all in one shot.so i guess ill install the 440's at the same time.that way i dont have to keep tuning.i wouldnt mind getting the 505 intake mani and installing at the same time but i havent got a pm back letting me know if there is actually one available still..i pmed him like a week ago no response......

You better forge your engine while you're at it. If you need 440s I don't think you're gonna be at stock boost. You're putting a lot of money in your car at once, but don't let it all be a worthless effort if you have a stock engine.

i will be fully building my block/head but im waitting till october when i take the car of the road for the winter.i understand that running a higher boost is risky but i believe i could run 11 psi with stock internals pretty safely.and if i do cause internal engine damage im not all that worried about it because it will just move the engine build up in the calander,but id like to be able to get through the summer season without downing my car for any long period of time..and doing a engine build with my work schedual would be difficult to complete in a timely fashion.but thanks for the advice its very important to forge your engine and i know this.

also wrx factory 440 injectors can be slightly modified and majicly turn into 800's. check on the wrx forums under free mods and they tell you how step by step. that is what i am doing do to my higher boost levels planed for 20+ psi. if you do that high of boost though ake sure your rings are gapped acordingly.

Good luck with the 11 psi. At that point, its a crapshoot. Your engine will either be ok with it or go kaboom.

..i understand that running a higher boost is risky but i believe i could run 11 psi with stock internals pretty safely...

You may be right, but you gotta realize that it's pretty risky to go above 10 psi on stock internals. Especially with just a piggyback for a tune. Some pull it off for years, others blow their engine in the first month.

...and if i do cause internal engine damage im not all that worried about it because it will just move the engine build up in the calander...

Again.. not exactly something I would recommend. 8/10 engine failures due to high boost result in a huge gaping hole on the side of the block, so your engine build at that point would not only include forged internals.. but also a new block.

Don't screw around man, if you're planning to run high boost.. get the supporting mods first, get a perfect tune at low boost second, THEN turn up the boost and adjust your tune accordingly.

SRT4 injectors will not plug and play. That injector uses a domestic style large upper Oring, while the MSP uses a smaller upper oring.
Not to say it cant be done, but you would have to modify the body of the injector to fit.

 

[Perf addict]

Do the stock wrx injectors are 440's? and in wich years they are drop in for the protege?

The DIY injector Mod for Subarus is pretty risky. I have serviced at least 30 sets of DIY injectors for customers after the modification who want them flowed. I would say maybe 5 sets have been within a 2% balance. Anything over 3% you is not good for a forced induction application.

For example, using just 4 modded injectors, your flowrates might vary from 830 to 880cc.

I have had customers send me 12 modded injectors and not get a set of 4 balanced within 3%.
