I am at 190k on my engine in a 84 GSL-SE. I of course want to get a new engine but there are so many options out there. Just want to hear the communities take on this matter. I want to get about 250 RWHP. I plan on using the car as a weekend car but also a track/ autocross machine.

I was thinking about the turbo2 swap. Easy for smog and good gain in horse. But I like the idea of staying NA. Plus everyone does the turbo2 swap.

My friend gave me the idea of just rebuilding my 13b. He pointed out that it's the 4 port. So a good street port and some ITB's would be a pretty good setup. But what kind of gain would I be looking at?

What are your thoughts, guys and gals?

Ps. I am not interested in piston swaps.

 

How can you have a 4 port? The GSL-SE had a 6 port. Please post some pictures. Then we can more easily help you decide what to do.

 

Yes 6 port. And it's the stock setup.

 

No one has helped you yet. Must be a slow day on the forum.

I'd say look for an S4 or S5 complete turbo swap, with ECU. Complete so there's no messing around with stuff trying to get to running. It will pass emissions which is important to you.

Do a search for Steve84GSTII. He did a complete S5 swap and it makes 300 reliable daily driven HP. Also passes draconian CA noise and emissions laws.

 

you're never going to get to 250rwhp N/A and be Cali-legal.


your only option is turbo2 swap..... or move lol

 

Keep it stock and more reliable. And it would cost less in the long run. And maybe less headaches.

On the other hand a turbo2 swap may be more fun in the short term. I think about that from time to time. Too many other things to take care of with the car. I'm in the middle of trying to make my se be the best it can be. or that I can afford.

 

i'd keep it stock if it were me.. but, that's just how i roll. i have some fast cars at my disposal so i just keep my 7's stock. they are more reliable, get better mileage and the SE's EGI engine will last a looong time if properly maintained.

to get the power you want, you will have to either swap in a largely ported 4 port 13B or do the T2 swap. hands down the easiest options you have. you will never see 250hp out of a N/A 6 port EGI engine

 

I got 360 whp and 354 ftlbs with my SA/LS1/T56/8.8 setup and I still have my 50/50. just an idea for ya

 

If money isn't a factor, then the sky is the limit. Otherwise, I wouldn't waste my time with a TII swap. Look at my signature, as I have an SE as well. With low cost mods, my SE is as fast as a stock TII. The last time I ran it, I ran a 15.4 1/4 mile and that was with bogging off the start, as I didn't have my RPM's up enough and launch right. I know as it sits, I can easily run high 14's, and I haven't done anything internally to the engine. All the parts that I purchased for the S5 intake were dirt cheap. The biggest expense was the exhaust. The flywheel I bought used and cheap. I would suggest starting out with all the common mods that guys do on their SE's and then consider doing a nice street port while you have the engine apart. If you invest in a good stand-alone ECU, then you will be turbo-ready. Just my thoughts :-)

 

stuff a v-8 into it, then upgrade the drive train........get all the HP you could want

 

I am intrigued, you bolted up a S5 intake to the SE's 13B? Were there mods that needed to be done to do this? Please tell me more, if you do not mind.
