Hey another noob, like you havn't heard this one b-4 . . .

[SPOOL_GSX]

Hey, wutsup everyone? I just sold my 1991 240sx for a 91 gsx, i know absolutley nothing about these cars, i am so serious, i was feaking out last night because when i was mashing on the gas the car would jolt and i thought my turbo was broke or something, but after a lil research i think that it is fuel cut-of, now the question is:how exactly do i get rid of it? Well My car is bone stock, and i just ordered sprint springs for it last night, i am putting an air filter on it today and buying a type-s B.O.V for it which i am going to reruit.
I need all the help i can get, i know how to use forums because i was a member of many 240 forums. What i am looking to do a conversion for the front to get rid of the pop up lights like a 92-94 conversion, what do you guys think? and where do i get them? Well thanx in advance for the help, i know how it is to answer the same questions oveer and over again to newbies.

your stock BOV is plenty because you have a 1g

go read www.vfaq.com and RREs website for hints on what to do: www.roadraceengineering.com

Don't ever really trust anything any dsm member tells you unless they are a wiseman

that is all the advice you need for right now.

I am sure you will get the "SEARCH" answer, but it is simple. You need to find the front body parts and start from there.


As for your fuel cut. It is all in the fuel. Is your car auto or manual?

There is 2 different routes for the 2 different setups.


I see that you are going to buy an airfilter and a new BOV. Did your car come with a boost gauge? Does it have a boost controller?

If not these things should be bought first....

Gauge
Controller
Filter
your BOV is perfectly fine (1G BOV)

fuel pump and some 550 injectors

then work on the exhaust side
then intake side

Keep the boost down till you can get the fuel situation figured out. You don't want detonation killing your engine prematurely.

your "fuel cut" is probably just a boost leak..... fuel cut is alittle more violent........

So does that mean he shouldnt trust you madgrl your not a wiseman. First off, no I am not a wiseman but I think I am knowledgeable enough to respond to this If your car is bone stock then I dont know how you could be experiencing fuel cut. You have not entered more fuel or more air into the equation. However I could be wrong but I dont think I am. Also you are saying your getting a jolt and im not sure what you mean by that but it does not sound like fuel cut. Madgrl is right about the bov though. Dont waste your money. There is an order to doing things look at the tuning guide bov will do nothing for you except maybe make it louder and who cares about that. Spend money wisely and you might acually get some performance out of it. Oh any wiseman out there please chime in and correct me or agree with me

It is either a leak or cut...

Hard to tell with no listings in the profile of the vehicle. I have seen some JOLTS that were pretty violent. If it is a slight hesitation then I would put it on a leak.

In any case, try this out and see if you find anything....

given that some members actually do know what they are talking about, I've received a lot of bad advice since I got my stock 1g back in June. . .so I'm always wary of the source. . .


as far as a 92-93 body part conversion. I'm all about the flip up lights. . .

 

[psychlow]

Fuel cut would feel like you're accelerating pretty good, and then you just ran into a brick wall. If it's just a hesitation, it's not fuel cut.

If it IS fuel cut, you'll need to check for boost leaks per this FAQ.

If it is just hesitation, you'll want to check the above plus check/replace your spark plugs, plug wires, and possibly your coilpack.

If after that you still haven't fixed the problems, let us know and we can tell you what to do from there.

I completely disagree with this. There are many knowledgable members here that do not have the wiseman title.

if the car is bone stock it shouldnt be fuel cut at all, even with my boost at 15 psi and full 3" exhaust i havent hit fuel cut with the car working properly, having that being said ur car probably isnt working properly if it is fuel cut.

Just to tell u about fuel cut since for someone new to dsms it might be kinda hard to tell, normally it will only happen at wide open throttle and when u have full boost cause thats where the most air is entering ur engine. When it does hit fuel cut the engine will basically just STOP for a second and u wont hear anything like normal engine combustion. U wont accelerate at all so it will jerk u forward quickly.

 

[sytrus]

if your car is stock you wouldn't be hitting fuel cut anyway, i wouldnt think. My friend's didn't start hitting that until they turned up the boost.

 

[SPOOL_GSX]

Hey guys, i am sorry i never received an e-mail saying someone replied to my post.
But i do think i have fuel cut-off, my car is bone-stock but only at WOT at full boost, and only sometimes the car shakes violently very very hard...like back injury hard. . .

And i am looking for a 3" cat-back exhaust that is a resonable price but performs and sounds good, i was looking at the HKS Hi-power exhaust, what do you guys think?

Thanx,

Tom

i wouldn't buy anything from HKS but cams. any of the domestic vendors can do better for you on exhaust.
