Engine/Transmission (1998.5 - 2002) Should I install these RV275's or not?

[Mick2500]

I bought a set of NEW Bosch RV275 injectors sometime in 2006 from Diesel Dynamics in Las Vegas(now defunct).
My 2001.5 HO 6-speed was running great with a TTPM at the time, so I put off installing them.
I sold the TTPM and bought a Smarty in 2008 and I kept putting off installing the RV275's. They have been
stored indoors in their original sealed plastic baggies, original Bosch foam lined boxes.
They have a very light oil coating on them and there is no discoloring or corrosion.
Is it safe to install them now? I have a set of new crossover o-rings coming next week just in case I
need them. I only have 38,000 miles on this truck as it shares duties with 4 motorcycles, 1 Vette
and my wife's BMW Z4 twin-turbo 6-speed.

Thanks,
Mick

I personally would have no issue putting them in whatsoever. You will like the 275's they are a nice little addition a bit more smoke probably good for 40 hp or so.

 

[klcammie]

Yes by all means install. I put in a set a year ago and wished I had done so sooner. You will love modest power boost. I have not had a smokey problem. Good thing to have the new o rings.

Mick, with an astounding 38,000 miles your truck is clearly worn out. Injectors won't make a lick of difference on that tired old rig.

Best to just sell it off to me, and go buy a new one


Of course I'm only kidding, that must be some truck! Good luck with the install, they will treat you well.

Thanks JR,
I'm sure I'm just overthinking this swap. I've built a couple of Chevy small blocks, two Kawasaki MCs and various
repairs over the years so this should be easy. The engine in my truck looks like new, it lives inside most of the time
and gets driven about 600 miles to Kalifornia when it gets out.
I used to pass through Andover on Rt7 just about every year with my folks when I was growing up down in Calcutta, OH.
I'm sure it's changed a LOT since I was there, used to spend two weeks in Ashtabula on lake Erie every summer.

Small world!

Not sure how long ago it's been, but in the 35 years I've been around Andover has gone largely unchanged. We still pride ourselves with having no traffic lights in town

Ashtabula on the other hand is another story. 90% of the industry that once made it a prominent town is long gone. Section 8 housing is rampant along with crimes and drugs. It's a mere shell of what it once was.

 

[Mick2500]

Sucks to hear that JR, I have not been back there since about 1998 and stayed close to the old homestead. It all
looked so run-down and empty, glad I'm far away.

I wouldnt hesitate installing those RV275's based on what you just described. They're fine and the HO motor wakes up nicely with injectors. And good thing you got some new crossover tube o-rings too because its best to replace them no matter what they look like. The installation job isnt difficult but if you find you need to ask some questions, I'd be more than happy to help.

But.....one thing you should know is that the 6-speed clutch is only good to about 60-70 HP over stock. So just understand that the likelihood is that you'll start to slip the clutch with those new injectors. Then be looking at another $1000 to replace it, yourself.

 

[Mick2500]

Another successful RV275 install! I installed 6 new crossover tube o-rings and lubed the injector o-rings with a little
vaseline and some engine oil over that, all 6 popped in easily and then I started the flare nut for the high pressure line and snugged it down a little, then I tightened the hold-down bolt to about 25inchlbs and loosened the flare nut till it was finger tight. tight. #5 and #6 ARE a b****
After I was all done, I put a new FS19856 fuel filter in, (the original was still in there and was not too dirty, must be good fuel around here). I primed the low pressure side about 15-20 times to fill the filter while watching my low pressure gauge attached to the VP44 inlet test port. Half the time I would see 6psi and then I would see 16.5psi. I removed the gauge
from the hose and bumped the starter, same thing, trickle and then a nice stream. I ran about 2 quarts into an old oil jug by repeated bumping and then re-attached the gauge, 16.5psi so I had my wife crank it while I watched #1, #3, #4 high pressure lines for spray. #4 sprayed first so I tightened it to 30ft.lbs., next was #3, then #1. It was attempting to run after about 4 attempts of 15-20 seconds so I let it start. It WAS a bit noisy for the first 10 seconds or so and then got quiet and
idled nice and smooth. Had a little blue smoke but that was gone in 20 seconds or so. I plan on taking it out for a test run a little later tonight, I want to let it set for a couple of hours to see how it starts cold.
So far, so good.

UPDATE: Started in about 2 seconds after sitting overnight, took it for a little test on flat ground, NICE! Can't wait for our
trip to Kalifornika in Nov-Dec pulling the hill on I-10 out of Indio will be fun. ) I don't tow anything but a
motorcycle trailer so it takes a big hill to build 30+ psi of boost.

Sounds like you got it all done nicely..... Good job.

But, DONT underestimate what I already warned about. The stock clutch can only hold back so much power and your Smarty combined with those new injectors will most likely crest its limit. So dont be too heavy on the skinny pedal until you're sure you want to replace that clutch. Especially while towing.

 

[klcammie]

Great to hear all went well. Not to hard of a job. Enjoy them 275's.

I've only slipped this clutch once about a 8 years ago and I caught it right away, If I stay in 3rd or 4th and keep the RPMs up, no slipping but I can't get on it much in the higher gears around 1800RPM. With my 315X75X17 BFGs, I'm right
around 2,000RPM at cruising speed our here in the west.

 

[KATOOM]

Just understand that the amount of pressure plate squeeze on the clutch disc is immense (approx 2800 lbs even for stock clutch) so when it barely slips or starts to slip under a heavy foot then the wear and heat build up means its all downhill from there as the clutches holding strength reduces significantly. Thats why I warned.

 

[Mick2500]

KA,
I fully understand the clamping force and I have not slipped my stock clutch since the one time in 2008 after I installed the
SMARTY and made the mistake of flooring it in 5th gear at about 1800RPM, never happened again.

Didnt mean to sound "preachy". Just informing in case you didnt already know.

Not a problem, thanks for watching out for the newbies.
