I have a question DSM related.
Posted 12/3/08 , edited 12/3/08
I have a 1990 plymouth laser 2.0l RS Turbo, basically the same thing as eagle talon or mitsubishi eclipse. I pull about 9-10 PSI on stock, but I have been searching and everyone says that stock build-up with a laser can easily go up to 13-14psi safely. Also it shouldnt be a problem since my motor and turbo just got a rebuild recently.

So the question is. Is there anyone here thats knowlegable about the car and have any suggestions?, I know i half to tinker on the Mass air flow sensor, and i know how to get the sensor out, but I do not know how to set it so i am getting 14 PSI. I dont want to even think about touching the inside of my car until i am sure i have some good instructions on how to do this, I am very careful when it comes to this car. So do any of you know how or have any links to detailed instructions on this matter? Thanks

First you have to do a few of the free mods. Take out the air silencer in the in intake. In the mas there is a screw in on the bottom that blocks airflow. You will need to back that screw out( its covered with silicone.) Next is to remove the lower honeycomb of the mas, that helps with a little flow restriction. Remove the bcs(boost control solenoid) that should allow you to see an extra 1lb boost. Change your spark plugs and get new NGK BPR6ES gaped to .28 and make sure your wires are good at that. After this is all accomplished then comes the aftermarket boost gauge and boost controller to up the boost. The stock boost gauge does not read actual boost and is inaccurate. A safe boost level for a stock 1g dsm is 16psi on stock injectors and pump but nothing over that.

The most important rule in modifying a DSM is maintenance. Make sure your on top of it(Timing belt, Timing tensioner, Water pump.)


Have fun with the laser. My first dsm was a 90 RS-T and now im on my 4th. I'll tell you one thing, you are going to have so many spare parts when you start modding your 1g. Ive got a garage and a half full of parts. If you have anymore questions feel free to ask.

Here are a few big DSM boards around. Just watch yourself though, they dont really like noobs that dont use the search button and you will have to write in perfect english and Cap your "I's" and use those periods. They are pretty anal at times but they are a good bunch.

For less than $300 I can get you running low to mid 13s easily. Hahaha.. I wanna see you guys do that with a honda or any other car.

Thanks a ton for the advice, and yeah, I usually forget some of my grammar on CR but im pretty good about it on the more serious sites. Also I did tried google, and just about all the searches to find anything on this but had some trouble, and since I remembered there where a few DSM pros around here, I thought id give it a try, glad I did too. If I have any other questions, ill make sure to ask.

Sorry but no personal threads allowed. I hope your question has been answered above though.
