Engine/Transmission (1998.5 - 2002) injector upgrade

[Floyd4runner]

My truck has intake and 4" strait pipe exh. I have an adrenaline that stays on 1 unloaded and L3 when loaded. This is my daily driver and not a hotrod. I drive like an old man. With that being said my truck is rolling over on 200k and I think I should change injectors this time when I run the valves. More maintenance than performance but might as well get something for your money. I was thinking of going with like a 50HP or 70HP set. Who makes a good reliable injector for a good price? Also what are the valve lash settings for a 99 24V auto? I fogot since the time. Thanks in advance. I love this forum.

Floyd the valves are . 010" intake and . 020" exhaust. If you drive like an old man and don't get the EGT up too high how about running them a bit tight at . 008" and . 017" (that's where I run mine). That'll sorta act like you have a bit larger cam.

For the injectors you could do the RV275s for $300 or so. Better than that would be Mach 1s. I have the Mach 1s and love them. I got 'em from Source Automotive.

I don't think you can beat the RV275's for the price and mild upgrade.

Thanks guy's. Where can I get the RV275's from, and also this is like a 75 HP injector right? What are the Mach1's?

275;s are more like 30 hp

I believe I bought my RV275's here:

Diesel performance parts, diesel truck parts, truck accesories, Arthurdale, WV

New and no core required if that matters but more costly $399.

Good for 40 Hp on the 235 Hp engine.

Good for 60 Hp on the 215 Hp engine.

Beware cheap injectors. I have a set of cheaper performance injectors from a smaller brand mentioned here. 35K and dribbling so much fuel you can't leave the truck idling. DDP only from here out. You get what you pay for.
