Advice?

[Stranglerwrangler88]

So I have a 1990 Plymouth laser N/T and I like driving it and wanna make it run a lot faster and I just wanna know would I be better off sellin the car and get the turbo version? I was thinkin about maybe stroking the motor and get the top end built and maybe just run some No2 at the strip or somethin but I just wanna know if that would be worth doin to a N/T car

Find out if you have the 1.8 4G37 or if you have the 2.0 4G63 engine.

If you have a 4G63 it is the same engine that comes on the turbo models (this is incorrect. The pistons in the 1G NT are weaker and there is a difference in compression ratio's.) and you can buy all the parts to turbo it and not have to worry about buying a whole new car.

I would only recommend this for someone with a decent amount of experience or if you have another car to drive while you learn about this one to work on it yourself.

Also, just as an FYI, it is much appreciated on this forum if you do a little searching before posting. When you do decide to post, use a more descriptive thread title and link to the posts that you have already read in the body of your post so we can see you have already searched a little. You won't get as much negative response if you do this. Trust me.

I was just wondering because from all the threads I've read it said that I would have to buy all the turbo parts , rebuild the motor, and get the computer, it just seemed cheaper to get another turboed car.

It is a 4g63..

It would definitely be easier to get a turbo'd car.

I don't know enough about the Laser's ECU/wiring harness to give you advice there but you would not have to rebuild the motor if its the 4G63 (this is also incorrect.) You could set up a 14b/t25 setup if you get all the parts together and bolt them on. (this is assuming you would not have to swap out the ECU)

Maybe someone with more knowledge about the Laser's ECU and harness can chime in. Hopefully it wouldn't be difficult to just throw an ECU from one of our other cars in there because you can find them relatively cheap in the classifieds. I'm pretty sure they made the Laser's turbocharged so if the other ECU's are not compatible than you could just get an ECU from one of those.

EDIT: I tend to edit my posts 4-5 times after first posting them so re read if necessary.

Yeah I don't know I read somethin about the compression being to much when turboing a N/T but I will definatly be collecting parts if I could do it without modding the motor right off hand

The compression in the NT is 9.0:1 as opposed to 7.8:1 in the Turbo model (1g), and you are correct in the NT pistons being weaker. If you planned to retain the stock pistons then the general accepted max boost pressure you can run is about 7psi. It is NOWHERE NEAR as easy as Angel makes it sound, but it can be done. Not without research on your part though.

I once had the same plans, but have since just upgraded cars. If you could afford it, I would just suggest getting a turbo car. And if this is your daily driver, NO.

Oh, and Nitrogen Dioxide will not make you faster.

Wow. I'm sorry. I completely forgot about the pistons being weaker in the non turbo. I completely change my opinion on this and say that you should buy a turbocharged model. I need to stop crossing over into posts about 1G's when I am much more familiar with 2G's.

I will go back and edit some parts in case someone searches this.

I'd have to disagree with this. Its all in how you plan on tuning it. I run 16 psi of boost on my 4g37...all original internals with over 200k on them, never been rebuilt, its a dd. I think everyone on this forum would agree that the 1.8 internals are weaker than the 2.0 even the non turbo ones.


I would recommend you getting a turbo ecu(you wont have to worry about tuning if you go this route), and then you will have to wire in a knock sensor into your engine harness. Grab some stock 450's and a turbo fuel pump and you should be good to go.

Please try again with a more descriptive thread title. A generic thread title like this does not help me when browsing new threads to see if I can offer help or when searching old threads for info to help myself or others.
