New custom short ram, now problems!

[s13 drifta]

I just put on my short ram intake on my ka24de and relocated my battery to the left side and now my s14 is running like crap below 3k rmps. It bogs for a sec when I step on the gas then it starts to rev a little after and then rpms jump around a lot when idling and sputters as well. I tried to mess with the idle screw but it didnt work. I only have one small vacumm line hooked up but I think by adding the bigger one should help. Any info you guys have would really help.

NO WAY!!! I couldn't imaging why not hooking up all the factory vacum lines would affect the engine.

Yeah this one time I put a new engine in my car but left out the pistons and dog gonnit the darned thing just never would run.

WTF?

Holy **** that is hard to think that a engine wouldnt run without pistons. I fixed my problem by the way thanks for helping.

well obvioulsy!!..

it ws a rotory....

The bigger line is what you MUST have for idle and everything.The smaller line goes into the intake manifold, for what I don't know yet. It also works with other crap for emissions.This is how I did minehttp://img211.imageshack.us/im...6.jpg

Yeah I just plugged my small vacumm line and hooked up the larger one and it runs a lot better now. Is it a good idea to block off the small vacumm line or not?

use common sense, route the lines back to their origin and figure out if can/should be deleted or not. There should be NO open connections to the atmosphere, but at the same time if you plug up certain lines your car will not run correctly.

Listen, this is not something you should explore on your own, there is a write up on this topic if you search. Use the writeup as a learning tool for this and later try experimenting on your own with something else once you have gathered up some experiance.

You can't just be plugging up or 'customizing' random things without knowing what their respective purpose is exactly, it is very unscientific and generally makes no sense.

Every part on the car has a job, if you don't understand what it does and how it works then you shouldnt mess with it. Its just a rule of thimb i suppose. Anyway good luck with your car

I didnt really feel like bumping this thread up because I already fixed my problem, but the only way I learn how to work on cars is by doing everything hands on. Ive learnt everything myself and the best way I learn is experimenting and trying to fix things instead of taking my cars to the shop. I dont know a whole lot and Im still learning stuff everyday, thats why I asked the question, and yes I tried searching, but I couldnt find anything useful.

[SPIRONIUM]

I didnt say anything about taking the car to the shop, i said there is an entire writeup on this subject so you can DIY without concluding the day with a thread about how you effed up something.

Search harder next time please: THAT is the best way to figure out what you are doing as opposed to experimenting

[s13 drifta]

Dude I have put on and taken off more intake systems than I can count, I think I know what Im doing. I was only experimenting with puting on a custom short ram on the right side. Please dont even reply and drop this thread.

Sorry, the pic I posted before had wrong air routing in it. This is the diagram corrected by a pro.http://img170.imageshack.us/im...2.jpg

I would advise against putting the battery on the left. The S-13 chassis was made for RIGHT hand drive with steering and driver weight there to offset the exhaust weight on the left. the USA left hand drive is already out of balance with too much weight on the left. If you lift the rear of the car with bigger wheels (one inch is enough) you will see that the car is tilted to the left.

[s13 drifta]

Yeah I was thinking about getting a light weight battery so it would have a better weight ratio, I will probably relocate it to the back later on.

Here's how to ACTUALLY make more power in a KA24DE.

Put in a thermostat that opens at lower temp (OE is 170'F) and better radiator. FRsports.com has a NISMO thermostat with 134'F.KA24DE intake manifold has a stupid design that passes the hot engine coolent around the intake manifold which heats it up and makes the air hot (less condensed)

Do that and you'll see a difference. Another way is to vent out more hot air from the engine bay.

coolant goes through the throttle body only, theres one line under the manifold but it doesnt go through it. Most cars have coolant passing through the throttle body, it is to prevent it from sticking, a saftey measure and in no way will hurt performance in any significantly measureable amount.

Making the cooling system more efficient will IN NO WAY help the performance of the engine. Running an engine constantly while it is not properly heated up will reduce the life of the motor.

The colder thermostat is for KA's that see A LOT of track days and/or live in a crazy hot environment, it is probably detrimental to the life of the motor if these things do not apply to you.

An upgraded radiator is simply a waste of money for a semi-close to stock KA. I'd like to see proof that it frees up HP because that just sounds rediculous to me.

[s13 drifta]

Yeah I run a nismo thermostat and it runs alot cooler than it did before. I know about doing the coolant bypass, but I rather just keep my coolant lines hooked up to the throttle body.

[Soravia]

Well that maybe true when it comes to colder climates. But where I'm at right now, it's so damn hot after 9am in the summer heat that I can't touch the metal plate on the air intake filter, let alone the intake manifold. A cooler engine bay will help a lot to get cooler air.

Anyone got a link to that guy who made a ghetto cold air isolation in his engine bay using windshield reflectors?

Found it. zerothread?id=252070

Damn, my engine bay looks like **** in that pic, it still does.

[s13 drifta]

Yeah I made a heat shield out of aluminum and it didnt look so bad, but now my intake is away from the header heat so I dont use it anymore.

[Soravia]

Want to sell me your stock box?

[s13 drifta]

sure, how much do you want to spend?

[Soravia]

It's OK, I just got an S-13 box and S-14 bottom from junkyard. The S-14 has three inlets.
