do you feel your car is a lot faster than before you installed the SC? have you pulled your plugs and see if you are running lean?


are you using the inline fuel pump from stillen? was is wired correctly?

gauges: I would get the EGT and fuel pressure. Forget about the A/F unless you are willing to spend some $ on a good one.

I've got basically the same setup right now and cruised through the hills then flatlands in California between Sacramento and Bakersfield doing 120 almost the whole way with no misfires....

So how did your engine blow? Is the jury still out? Could you let us know once you find out?

Thanks!

And I've done 0-130 on the Dyno many many many times - which is even worse - not moving = no airflow = lots of heat.

I pulled the plugs out the front bank. . .. they look burnt. . is that normal? I am running the pr5gk or something. . one step colder NGKs. . . should I replace those as well when I rebuild my engine?

inline fuel pump? errr. . . keep in mind that I didn't start looking at performance mods for my car until very recently, so I don't know too much about all this. Also, the s/c was installed by my mechanic, soooo. .. I assume the pump was wired correctly? if the kit came with one, then I have it.

Thinking of also performing some weight reduction on my car when I get it back by replacing my 2 12" subs in the custom trunk with a single 10" in a bandpass and getting lighter rims instead of them chrome 18s".. . If you guys have never seen my car before. . . . here's a link.. .

Flew up the H3 (steep inclined Highway in Hawaii) at 115 mph (yah yah dangerous to drive fast on public roads but I made sure all conditions were safe before I did such a thing... irrelevant to post so please keep comments to self concerning this) heard the <A TITLE="Click for more information about car" STYLE="background-color: #f0f000; " HREF="http://search.targetwords.com/u.search?x=5977|1||||cars|AA1VDw">car</A> make some rattling at WOT.. . like a rapid ticking, and then poof.. a cloud of smoke came out of my exhaust. . . Then my speed rapidly dropped, so I think I must of lost a cylinder or two.... the high boost and the intense load on the car played a factor in this. ..

The wonderful Maxima guys on the cruise helped me diagnose the following:
ecu code - multiple cylinder misfire. .. i think it was 7-1. . .
got engine oil coming out the exhaust
engine oil all over the engine bay (due to it coming out of the breather valve)
HAd to get the car towed to my mechanic, but the car still starts and there is still pressure in the radiator. No oil in the radiator, no oil in the intake.. . initial diagnosis is that I busted a piston or a ring, or blew the head gasket. No time for a compression check either.

Have decided to go ahead and rebuild the engine...
Ordered 9:1 compression pistons and new rods, rings, wrist pins, blah blah gaskets.

I have read that aftermarket cams/valves/springs/retainers are unnecessary since I'm already boosted and the stock stuff holds up pretty well. Also read that since I'm not boosting very high, I will not need to Darton sleeve my cylinders.

Currently the set up is 3.125 pulley on a V2 s/c kit with 8:1 FMU disc. I have a tranny cooler and Don's VB mod. I don't plan on runnin any smaller pulley than the 3.125 and if I did want more hp, i would most likely go with a MEVI.

Now, I guess my question for you peeps is what else do I need to finish this up.

I have considered the following by using the infamous search function but I have no clue where to get these things or if I even need all of it. If I get one thing, will I have to get all the rest? shrugs.. .

255 lph walbro fuel pump - Allgo had offered to sell me his
fuel pressure regulator (wut brand, model, and where to buy from)
370 cc fuel injectors
JWT ECU - but I have a '99, will it work?
ARP stud set - where do I get this from?

In terms of gauges, I had originally only had a boost gauge, but now I plan on adding a/f, oil pressure, and oil temp. I have heard mixed comments about getting EGT some say yes, some say it's not that necessary.

Thanks for the help in advance, I have a hard time distinguishing who is bull****ting and who actually knows what they're talking about so please, if you really don't know, don't post.

p.s. and you know what the worst part of this is? The 5th gen was on my *** the whole time..... something must seriously be wrong... shouldn't I be pushing at least 250 hp vs his 227?

How many miles did you have on the motor anyways?

See my post above.

It obviously sounds like you were running lean : detonation + boost = BOOM.

Oil spitting out of the tail pipes, coolant levels fine, Have no clue at this point what blew it, happened at about 120mph, They all are 99 auto's. Think we have something here? I just got my full engine update and will post soon

but once it was fixed.....the AFR dropped to < 10:1.

again....if he had EGT and fuel pressure gauge, it will be easier to find out the cause of this problem.
