best injectors for PMR's

sidwaz · Feb 22, 2012

What are the best injectors to use with PMR's. I have a gt38r and a dp tuner f6. Would like to make 400-450 rwhp. I only want to but injectors once. I was tinking about Swamps 200/30 or maybe Casserly 238's. Suggestions?

Why add power on top of a known problem?

With injectors I say go beyond your goals and tune to where you want it.

238/100s would be my vote.

Cass 238/100s and tune to the level u want!

I'm running 250/200's on PMR's right now. I would never go with a small 30% nozzle if you're trying to make over 400 rwhp... unless you like high EGT's.

Every time I see one of these threads about "what injectors are best" for whatever unstated purpose - I want to answer 400/400s.

What are your plans? Goals? Usage? Requirements? Give us something. If you want us to tell you what injectors will allow your PMR motor to live forever - the correct answer is NONE - not even stock. If you understand the risk of modifications, understand that you need to get some tuning for the new sticks that keeps cylinder pressures in check, etc.... then I STILL can't answer your question because I don't know what you want to do with the truck. Stage 1s might be perfect for you - 300/200 hybrids could be where its at. Everything has a level of risk and a level of performance - its a matter of knowing what level of risk is acceptable and what level of performance you wish to achieve.

Unlimited's 238/80's or 100's. That will get you right there at your power goal.

I was @ 430rwhp (92.2@8200lbs) for 2 yrs with those inj. Still running them today with zero complaints...

Making a peak power number tells me nothing about how he wants to run and drive his truck, or what level of risk is acceptable to him.

I'm not saying your answer is wrong - but 400 ponies can be made with the supporting mods on a set of single shot stage 1s. Why not recommend those sticks over the hybrids?

I use the truck as a daily driver and only tow under 10k occasionally. With the stock gearing on a 6spd with 37's could use so more power. Clutch is only rated to 450 and I realize the risks involved with PMR motors but I do see quite a few poeple as of late with more luck. Tuning has come a long ways in the past few years. I am leaning towards 238/100%, can I run anybody's tuning on the F6?

I'm happy with my combo, but I'm also somewhat prepared if it decides to blow. Depends if you want to always have that in the back of your head or not.

You beat me to it LOL

F6 is gonna be Jody's tunes only.

And, while there are a handful of injector combo's to make your peak power goal, what's been said prior about truck use is the real question.

Also, IMHO opinion it's much more about tuning than injector when you're tryin to keep an engine together.

PMRs and bad tuning = Chvys avatar

mattman347 · Feb 23, 2012

PMR's and anything extra could spell trouble. I am running 238/100's on a 2003 PMR truck that just has an intake and stock exhaust. It really is all in the tuning and little luck.

Stock! LOL

I'm running 250cc injectors on my 2002.

TyCorr · Feb 23, 2012

Id buy some rodswith the inj's or just be prepared for it to blow.

If you.drive aggressively this is just a bad idea. The small hybrids will run clean though, with good tunes.

Derek@Vision Diesel · Feb 23, 2012

There is not a best injector for a PMR engine. But a properly functioning one with great tuning will go a very long way to keeping your motor together.

The biggest term being TUNING. Dont risk it, get it live tuned
