Steveman09 Posted April 8, 2007 Share Posted April 8, 2007 Well I dont know if anyone was following my serious LEAN/Hesitation Issue latly but after a high speed run to the beach I noticed a loss in power and boost wasnt holding. Also noticed Blue smoke out the back. Got it back and did a compression test : 150-146-142-65psi #4 65psi Tore the block out and inspected it to find this : Seems as #4 was running extremly LEAN and Detonating!!!!! chunk of piston missing I had the injectors flowed and it turns out #4 was screwed up so that was the problem the whole time but I didnt catch it in time. Well I just finished installing another new SOA shortblock around 7pm hopfing to get it running for Subiefest but I just couldnt make it. Sorry to everyone who wanted to see it. Anyways Just had to vent a llittle. Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted April 8, 2007 Share Posted April 8, 2007 Had that happen on my EJ22. $600 into rebuilding the engine, ran great, but appanently lean on #3 injector. Smoked the cyl and a valve, put a spare head on, smoked that valve too, then figured out it was running lean. one little injector can really ruin a well built motor. That sucks bad man.

Turbone Posted April 8, 2007 Share Posted April 8, 2007 Hmmm, sounds like I might do some injector cleaning:rolleyes: Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted April 8, 2007 Share Posted April 8, 2007 Why those Things Happens? ...one little injector can really ruin a well built motor. That sucks bad man. If that was Due to a Bad Injector, it Really Sucks! :-\ it Means that a Carburetor Never can do that Damage... isn´t it? Well... Good Luck with the New Asembly! ... Pics Please!

Essentially, you are right. That particular problem is something that only a TPI (tuned port injection) system can have. Steveman, you were the one with the BRAND NEW shortblock ea82T, right?? was that a turbo compression motor, or an NA block? that sucks, man.. to be done in by something STUPID like that....

joostvdw Posted April 9, 2007 Share Posted April 9, 2007 yeap brand new soa shortblock Ea82T I racked up 20,000miles of pure fun tho you can always put a new piston in and have a almost new SOA short block Quote Link to comment Share on other sites More sharing options...
Steveman09 Posted April 9, 2007 Author Share Posted April 9, 2007 you can always put a new piston in and have a almost new SOA short block I allready swapped the block for another brand new one Quote Link to comment Share on other sites More sharing options...
joostvdw Posted April 9, 2007 Share Posted April 9, 2007 I allready swapped the block for another brand new one oh yeah why not, just shovel some more cash towards it I think it is great you are willing to spend so much time and money on something you end op blowing up again j/k but now more serious, I really do think you are doing a good job, I might have done some things differently but it's the results that count Quote Link to comment Share on other sites More sharing options...
daeron Posted April 9, 2007 Share Posted April 9, 2007 Steve, what kind of injectors are you running again? I ask because I have a butt-load of 280ZX (mostly NA ZX) injectors that I need to sort through and clean and test, it is a project that has been on my to-do list for a long time... but I havent prioritized it. If you could use some new injectors (IE, double set) I could "get around" to doing this stuff very soon and send you a set out on the cheap.. these are parts I need to move anyhow. PM me if youre at all interested.. I realize that you are likely already running higher flow injectors than what Ive got, but I figured I would offer/mention it.

Had the injectors flowed, #4 flowed 53% less fuel than others. This new shortblock didnt cost me anything since I was able to warranty out another one since I know the parts manager. I have a brand new set of injectors for it from Venom that are 360cc that I will be installing, the injectors that failed were the 280ZX Turbo Injectors. Keep in mind I had 20,000miles of hard abusive driving on that block/build and the compression test showed near perfect compression on all other cylinders, so if it wasnt for the injectors the engine would still be running. BTW Total Project Price 3 motors later and price of buying car = $5000/give or take a few bucks. 5k for a 12-13second car isnt bad. Quote Link to comment Share on other sites More sharing options...

Amen to ALL of the above, and envy projected over your mad engine block hookups... Had to ask about the injectors, even though I think i recall reading something elsewhere about your future plans. Good to see that after 20K the block was still in good shape otherwise. More fuel should be good, i bet it evens things out even more than you anticipate. Hope everything goes back together well.

Don't want that happening on Elly. Quote Link to comment Share on other sites More sharing options...
