96 Beretta Project

I don't know nitrous systems well, but why can't you just run 43 psi like your injectors, with a tighter orifice in the nozzles?

Now for Direct Port I need to drop my fuel pressure at the solenoid to the 8-12 range to allow for a larger fuel jet to prevent any possible clogs. If I kept the pressure at 55PSI then I would need a VERY small jet and the nitrous guys say that's just asking for a disaster.

I'm kind of curious why a tiny jet at higher pressure will be an issue with good filtering.

Well I could and that was what I was originally going to do, but having 6 jets and only a 100 shot the orfice is very small and many told me that is a bad idea and could clog very easily. Granted fuel injectors probably have very similar small exit holes but it's hard to even find the jet I need because it's so small.

well, there's an easy solution to that as well, run a 200 shot!... lol. on a serious note though, is your "100 shot" corrected for 6 cylinders? a direct port 100 shot setup for a v8 is only going to net 75 on a V6.

Jet size was determined by amount of nozzles and fuel/bottle pressure.

[ericjon262]

to me, your best option sounds like upgrading your fuel filter, maybe even a dual filter setup, instead of a dual regulator setup.

I'm leaning towards the same... Only NX has a jet small enough tho... I'm looking at a 0.020 nitrous jet and roughly a 0.010 - 0.012 fuel jet.

Some charts only list a 75 shot and a 150 for direct port so I need to shoot in the middle kind of.

Ok, new cam should be getting ordered today when I know if I need new pushrods.

I went all out and need to also swap valve springs.

Oh and due to this change I think that I'm going to Time-Sert my heads for the rocker threads... last thing I need is a rocker ripping out because of the increased spring load, and these rockers have been on and off their fair share of times so I'm sure the threads are beginning to wear just as my exhaust manifold ones did.

Not a bad idea. Hell, I blew the #2 exhaust rocker out of a stock '03 3400...

Got the kit... looks nice. Inserts will be going in with a dab of red loctite on them just for insurance.

Well, everything is at the machine shop... Heads block and bottom end... He's going to start on the balancing and head work and then when I get the ARP main studs he'll do the line bore check block decking and cylinder hone/cleaning. I hate waiting for machine work... LOL

Now it's onto the little nickle and dime items... Started to tear apart the AC compressor to see if I can replace the o-rings on the body and seal it back up if all is well inside... I will also be attempting to replace the Expansion valve since I believe that's the cause to my AC never really being cold as it should have. I will also throw a new dryer at it.

I also pulled apart my old fuel pump assembly and harvested the stock bucket and parts from my 95... I swapped all of that in with my old Walbro F20000169 pump that I had lying around... My existing setup was a GSS340 Walbro with a cut up bucket... This new configuration uses all stock components in the pickup... I'm hoping that will work and not give me issues with sucking the bucket dry... if it does its back to the GSS340 setup since that worked OK, I just need to refine how it reaches the bottom of the tank.

I'm debating starting in on the trans but I don't want to be in the middle of that all torn apart and have my engine stuff be ready... One project at a time but I feel that I can finish the trans rather quick as long as the TCC lockup failure did not damage anything else in there.

Any opinions on swapping in the 2244152V oil pump?

Sealed power lists that as an option for the 96 Beretta and it's non high volume counterpart 2244152 is listed to fit both the 96 Beretta and 04 3500 Malibu... So even though RA doesn't list the V style pump for the 3500 It's safe to say it will most likely fit.

Is it weird when you spend all night working on your 12sec car but you were working on fixing/rebuilding the A/C? lol

Compressor rebuild in process and expansion valve removed... Man I hate doing a heater core on these cars.

All the presents show up on the same day but now the machine shop is the delay.... Wahoo a rhyme!
