ok... i need to get a new rubber elbow. 2.25" anyone know where to get one?
so for my new setup ( actually not really new, just got some new things added), greddy 3" evo2 cat back, new 2.5" down pipe, greddy profec b spec2 controller, and a NEW equal length manifold! i went from 5psi to 10psi, sometimes spikes to 11-12psi. and so far so good, havent had it on the dyno yet but i can only guesstimate maybe 250whp!
for those with bigger turbos, when do you guys see full boost? the problem i have is that its soo late when it spools up but when it does, its kinda violent! ill get my normal 5psi@ 4500-5000 and then just jumps to 10psi or so! i tried messing around with my profec. i have it set for 10 psi (7.5 on the profec) and my gains are 25%. any help would be apreciated. ill post pics soon, now that i have a new digi cam and not my cell phone!!!

You should be able to find a rubber elbow at a local performance shop. How is you A/F mixtures at 10psi? You still running on stock injectors? I was boosting at around 8psi before and would be rich anything after 8psi my car would go lean. But now I'm back to 5psi until I upgrade my injectors. On my T3/T04 I'm fully boosting 5psi @ 3500

sean. i have an oil pressure guage, a boost/vac gauge, and a digital egt. the last time i dynoed, my a/f looked like it was bang on. i only have a rising rate fmu and a hks super afr to control fuel if need be, but as of right now, theres really no need. plus i dont boost to 10psi on a regular basis, only on those hard runs!. i know it only takes a split second before i toast something, but thats the risk that im definitly willing to take!
im not really concerned about my a/f as much as i am concerned about my block. if i really need more fuel, i have a set of blue top injectors that im ready to drop in! there was some 2gnt guys a few years back saying the stock block handles 14-15psi before they started to bend rods! but i also remember them saying that they abused the **** outta those motors (for educations sake, obviosly!).

Dont forget guys, I'm running a 16 at up to 15psi on a non turbo motor, but my car was originally a turbo car, so I have all the turbo parts(ecu, injectors, ect.) I get no knock at 15psi. Just so u know. Been running 11 for 3 years, i hit 15psi(profec A) if I'm racing something realy fast. Have had no problems, and no rods bending.

Originally posted by Sean Raymer: Just curious, what is your compression on all 4 cylinders? what condition are your stock rods/pistons and crank/bearings in? From what i've read on 2gnt most guys are lucky if they can run 8-10psi on a stock block/internals, max i've seen is 12psi. Every engine is different, your internals could be near perfect where someone else may have below-average or visa-versa its impossible to tell... so to say I can do it because others have is far-fetched. Why risk ****ing up your stock rods/pistons/crank and possibly more by running too high boost, run a safe level of boost, save up for a proper rebuild then do it right the first time.
sidenote: What psi did you dyno/tune at? what were your numbers (a/f, hp, trq)? I'd definitely heed his advice. 420A are not designed for boost. The pin connecting one of my rods to the piston was in pretty bad shape. And I had it @ 6 psi. Like he said. If you want to go all out. Keep it at low boost and save $$$ for a rebuild. Otherwise you'll be stuck with a blown motor. The block of the engine is pretty damn solidly built. But the rest is not so great, especially the notorious headgasket . So watch out. And I'd also watch out for the clutch. Mine already had a crack in it. BTW my spool. Well, the turbo is a T3/T4 with E-compressor sized housing. And if it spooled any faster, I'd be going into boost at idle. )

Or better yet, pick up another 420A, and rebuild it. THEN, boost the crap out of the one in the car. When it blows, all you'll have to do is swap in the rebuild. That should keep the down-time to a minimum.
