AdR: sorry Im an engineer by profession an been real busy the past few days so havent had time to check on the things you have mentioned, but Thanks for your help, ive searched many places to find the link between the maf and factory boost gauge and never seen anything on the matter matter. I...

ONEFAST2GDSM: you DUMBFU*K guess you cannot read the dsmtuners message directly below the reply box????? Nvm dont answer i dont care to here your response leave my post your a worthless pos net troll...btw you lean it at wot cause a 2g dsm typically runs 10:2 afr at wot.maybe you should learn a...

Oneslowdsm: you did mention something that caught my attention though.... You say a 255 will overun the stock fpr (how is that?) i was thinking about putting a afpr on my shelf on it but kept saying, im getting a lean cond not a rich one.

Slowwhite: thanks for your help post being you are the only one who did post something possibly helpfulThe rest of you: thanks i suppose for your suggestion to tune ecu but considering i alrdy knew that you done me no good...i stated ive been lookn into this for a while now, car run the same...

Stated that car is all stock except what i oosted isnt stock. Up and down meaning values in the safc2. Ive owned many turbo cars along with made many cars turbo using apexi products so id like to think i know them but maybe you know more!? That sentence should have read "car pulls hard WITHOUT...

Hello all, been a while as i dont frequent forums often but im somewhat stumped. No better place to seek advice than here. Ok so I have searched to no end without any bit of a logical answer. 98 gst 5spd- 99gsx blackbox,walbro 255, fmic, hard intake pipe, bov dumped,safc2, 14psi stock turbo. Car...

Plug wires are 10.2mm.none bad. Regular timing lite and it wasnt doing it on the chevy truck i was working on for someone earlier in the day, nor has it ever that ive seen. Added a 8g ground from firewall to tb. Seemed to help although coulda just been the cool air at night. Cel has popped on...

[/QUOTE=]haha yeah I no lol u gotta crawl b4 u walk kind ordealThanksHaha...no doubt By the way, $400 is only going to get your car running. Surely not in the ballpark of modding it.

Thx fellows. Also DREAM: why does your av show 15 sec pass @100. Mph an time dont match...

Nevermind since my grammer isnt my issue.the car is! And the paragraph has enough periods and a question mark that it can be understood. Thx though

Ok thx. So evoscan isnt used for flashing. Ecuflash is. So ecuflash, op 2.0 cable an mitsu reflash is all needed correct

So my car was tuned by a neo. In a 240sx now cause im wanting evoscan. Can evoscan control boost relevant to gearing(1st@10,2nd@15,3rd@20) an so on? Also its a 98gst with a 99gsx ecu, so all i need is the cable my laptop an download evoscan software an tune to my liking correct? An is there...

So car seems to be surging below 3k an sometimes above 5500 kinda like timing to low or detonation. Timing lite shows it bouncing between 5_10 btdc at idle but thats not a true base reading i know but problem is my timing lite is showing an irratic flashing during its normal pattern. Whats...

HELL YEAH its a problem..... People throw them away and there not common aftermarket cause they come factory.. I used a license plate to cut mine from..lol liteweight!

I posted some months back about modding the 2g bov using a shotgun magtube spring,it will hold upwards of 20 or more depending how long you cut the spring

Oh yeah,the rs was a turbo factory(tried to buy on from an old lady bout 5yrs ago) The way he posted it i thought he meant n/a turbo.So no, a 14b cant create the cylinder pressures need to make 300hp from a low comp 2liter engine

Sorry, edited that to make sense.. This is a high comp engine correct n/a stock?

Alot of ppl are think this is a low comp gst but its not. It had what 140hp stock plus 13pis is prob bout 150hp with the i/c so its not so hard to believe he could be at 300 pending weather conditions.This was a n/a 4g63 correct?

Resolved... 99 gsx ecu 359403 is plug an go without needing to be reprogrammed.

RESOLVED... installed 99 gsx ecu 359403, plug and go. Passed after 8 mile drive. I had looked many places to see if it would need programming to my 98gst but never an answer. IT WILL PLUG AN DRIVE, NO PROGRAM NEEDED.

Its not goin to hurt anything immediately, but will probly break the turbo in a few thousand miles. Explain again how its running 14psi on the stock solenoid?

Exactlly this^^^An it will never change Cooler air =more power Test the theory of air being split by an object(in this case,two ways.through the ic an across it.) and see doesnt it cool faster because of the spliting effect. Molecules are molecules and we cant change science.

The bov leaks at 13psi not before, if you are mbc to above 14psi then the turbo is running nearly wide open because there is a leak(bov). Did u pinch the fuel return line cause more fuel pressure? When installing the starter.

No. Not if you mean push the fork in by your finger. Hint as to why they use hydraulic pressure to do it.

No reason to name call about one problem,to many other things you would agree on. Anyway as to the op and pte- if you ran a stock gst turbo at 21psi (which it will do) very long, the shaft WILL break guaranteed! Done it a few times... Do you think mitsu is going to make that mistake right...

You simply cant rate a part by hp ability, to many things come into account that will due damage to many mechanical parts of an engine/turbo an so on. Granted at 40+psi the turbo is catching hell an if cooled it would significantly reduced that "hell". Point being is its just as much pte as the...

B-n-l had this with a 96 420a car. Similar symptoms but it would blow a fuse. Cause was a wiring harness rubbing an shorted. It was intermittent though so was a bi*** to find. If memory serves, it was the bulk part over the trans close to the battery tray. Dont hold me to that though

Op your close by your guess, from my experience. The na side of your engine is prob adding 35-40hp at that drop,on the boost side a little more. Someone mentioned altitudes,from sea level to say 6000ft a retune would yield significant gains because air thins and moisture increases most of the...

ONLY WAY TO BECOME A GREAT MECHANIC, IS TO BE A MECHANIC!show daddy this and see what he replies. At age 15 my dad already knew he had nothing to worry about cause of what he had seen me do when he wasnt around ;)

Looks like an adjustable nissan fpr to me. Some had them or could be bought for them. Zxtts an things

Been in the clump of asphalt in the road shyt before to... Dam d.o.t!

Hi, you said a street car running maybe 9s? Being single digits. To start purpose built drag cars arent fun on the streets in my op, because a purpose built drag should be auto for many reasons and we all know autos are boring on the street. Theres a big reason not to spend time shifting in a...

Yep had the same problem, it splits an slings the grease out..have fun cleaning it of everything under there...

Not possible for a fuel pump to quit an build fuel pressure at the same time. Now the pump motor could run but not pump fuel but it will jus whine with no fuel pumping.Pull the fuel line to the afpr an see whats coming out. The fp can pump air if its suckin air on the in side of the pump but...

Got so busy i missed a few post, i was just about to ask how rich do they run stock at wot on a wideband, you just answered that.... SO UPDATE IS.. got it at 10:1 so guess its right now. Had to run cross state for them dam injector insulators got them on lastnight. well 10.1 is way to...

Sorry bro, got tied up building a ka-t and slipped my mind. I have that bulletin and it means nothing to big boys at NCDMV. even ask them to shutdown i-40 so i could try mitsu's BS way to set them...since he said twice that "you have to show spending $200 on repairs,and it still failed for a...

Seriously dude? Thats your idea of helping. Not to be the ass of dsm but if he had/could afford dsmlink, his thread would say "dsmlink problems" and besides if he doesn't have something wired right dsmlink won't work either.OP karman setups on most afc's use a diiferent set of air flow...

Should b fine. I assume thats with tp closed? Either way it should be fine

The tire pressure gauges that are round like a gauge and some have a tire around them are jus gauges with 1/8" npt threads,the valve part unscrews an there like $6. U could use that. Most read 1psi increments. Advance,az, even walmart sells them around the airtools section. mayb this helps...

Mls gaskets are terrible about sealing unless a machinist sends alot of time with the deck and head, I've about got to where I'll use a stock gasket below 500whp cause of this.just not worth the time to pull the head 2-3 times. And rings often seat after a good bit of miles and heat since i...

Cool, all my years in cars I've never noticed gains from them, although its not always silicon sometimes it's resistance that is changed but like i said being it's a stock ignition system i didnt know if they had purpose in helping it.thx fellas

Slept allday so didnt get a chance, gona chk an see if my wife still has the pic on her phone an if so ill post it.. Most that have seen that pic or my car described it as Sexy... Maybe that helps. Also my car is blk, kinda makes a difference i think.That silver bottom looks ok not really...

My car has 10.2 vms wires on it from back when i bought the car, has anyone seen a proven gain from bigarse plug wires or can i just get this over lentgh bulky cluster ph%$k of wires off my car... Stock ign system btw.

Exactly, not 3grand where that come from..

Jus remember when gaping plugs if you get to small it will idle like shyt dont think its a problem with something else. Also you said bad gas..... Fill that b***h with 93 an maybe a lil av fuel if you got an airport nearby.. Do you have a wideband? Is it tuned with anything?

Forgot to add lasnight that the adjustment screw in the tb is leakin boost like hell to... No leaks goin to the intake just all over the intake lol.

Stock bovs do lift at 13-14 psi,all of them.., My fix for that- a shotgun magazine tube spring about 2.5" long spun around the shaft in the bov....good for up of 20psi ;)

Ill see if i can get some today, burnt my phone 2wks ago an lost everything i had on sd card....cry'd like a baby when that happened...

Start here because you know nothing about this car yet--> Erase all codes with a scan tool not by removing the neg cable. Unplug the boost controller(no need to get unhappy ;)- Plug back to the stock solenoid. U should be around 10psi.. If not mbc an set it there Change the spark plugs...
