Im planing on boosting on a stock block, but i will P&P the head but im not sure what size injector should i use. Since I'm learning as I go is kind of hard for me to figure out which size. And by the way I will use a GT35R.

I think you'd be ok with 450cc's or so.

what kind of power are you trying to make? The answer to this question will dictate the smallest sized injector that you would need . . . but personally, i would buy/run larger injectors to leave room for making more power later . . . i currently sport 1600's . . . but 750-880's should please you (and let you make up to 450-500 hp down the road)

Yup- how much power?

On a stock block with a GT35R, I would run 800-900cc injectors- but that's with the power that I know I could make with good tuning.

Well, im not sure how much ill be able to make with a stock block but I when I sleeve the block, I plan to shoot for the 600 HP range, so should I just buy one size and get it over with, and if so which one. And if it helps it will be going to evens-tuning,

How long will it be before you go for the higher power goal? If it's going to be a while, you don't want to get monster injectors up front. You'll lose a lot of tuning resolution when you're trying to trim things in.

Considering that resleeving a block with new internals is a pretty comprehensive rebuild, I think that it would be a while before you would need to get the huge injectors, right? I would get a properly sized set now, then get another set later. Yeah, you'll spend a bit more money doing it, but your engine will thank you for it.

most likely Ill have the car on the stock block for about a year, so how about some 450s or 550s with the worked head I'm hoping ill be making more than 300 hp, ill see how much HP this guy jeff can pull out of the motor, if he's a good as everynone says he is, then well see. But I havent even called that shop yet, this is speculation for now.

IM buying and earls inline fuel filter, should i get the one with the 6AN male or 8AN Male does it make a difference at all

cheapest way to be safe with boost would be some DSM injectors 440cc plug and play with OBD1 injector clips.

I'll see cuz i got a 97 rs

It's not plug-n-play for you at all...yes you need to swap in OBD1 clips, but DSM's are also low-impedance so you'd have to install a resistor box too. Personally I'd get some lightly used saturated RC's. Usually you can pick them up for like $200 or so, although I've seen them for less sometimes. You never know what you're getting with a 10+yr old set of DSM's, the flow rates might not match, or some other such thing.
