olds bravada

[bdydrpds10]

I've been looking at 1992-1994 Olds Bravadas. I thought the engines were the same as my 93 s-10 4.3 ....but the hp rating is 200 on the bravada. and I beleive they are mpi/cpi? instead of tbi. My question is where can I find performance parts for the bravada 4.3? Are they the same as chevy 4.3's? Why the hp difference. Even the 1994 vortec blazer motors are not rated at 200.

It's a Chevy 4.3L CPI

I have a cpi..

it sucks

no real performance parts for it..
one fuel injector, working 6 times as hard as any others.. dies every 30-60k miles.. $200-300 part..

other than that, its the most powerful NA 4.3

The rating for Bravada's is 200hp. It's also the same on the GMC Jimmy SLT and Blazer Tahoe. The method of injection is central port injection (CPI) and it is horrible!!! Although TBI is pretty much an electric carburetor. However they are semi reliable. Only had to fix it once although I still have gas in my oil. That works for me though because now I only have to change the oil every 10k miles!!!

Thanks for the info. I guess that motor doesn't have too many options for bolt-ons.

i have had great luck with the cpi in my 94 blazer. 235k on it and the inj. and line kit were replaced only one time under warrenty. it still has the orignal water pump and tranny only thing i have changed is the fuel pump and cooler lines. dosent smoke or leak a drop. but it also cant pull a greasy string out of a cats ass.

my daily driver is a 95 2dr 4x4 blazer with the CMPI 4.3
it has lasted me roughly 60k miles so far, I've replaced the injector once, replaced the ball joints twice and a few other things a couple of times..

overall its a great DD, but recently its starting to show its 124k miles.. the starter is pretty much covered in oil (not sure from where, probably the rear main) and the undercarriage is a mess..

the tranny feels like its starting to slip, and the exhaust is in dire need of being replaced..

other than that, it gets me to work everyday, and i don't mind driving it.

Eric, you know half the time the regulater is what goes bad.......Not the whole 'spider'

 

[ericguy320]

i see it half and half when they come through the shop, the regulator or the lines will melt or a hole will rub through them.

i have always had luck with all my cpi motors. my winter beater is a 93 cpi with almost 200,000 on it. and still runs stong. the only thing i hate is the 4l60e tranny. dont like the way it shifts

put a corvette servo in it. They make some other parts for it to a new seperator (spelling) plate.

 

[syclonekid43]

ill have to keep that in mind. anybody know the part number by chance?

two of my lines actually cracked in half..

it was a HUGE bitch to get the "injector" piece out of the hole in the bottom of the intake..

and no i had no idea it could have been the regulator.. the symptoms it was showing at the time, were purely gas in the upper intake manifold..

when i took it off, carbon everywhere on one side, and clean as a whistle on the other..

The FPR goes bad then it overfuels. or like you had a broken line.
