ok so i know that thier is million threads about boosting the ls engine. But i want to know what the engine can handle(and for how long) on bone stock internals. I want to get the ls swap and run it na for a month or two till i get the parts & money for a turbo,but i dont want to upgrade the internals. i have a poor mans gsr that is currently in my 98 civic coupe but it isnt running nd i need a dd right now. so i want to but the ls swap in nd have as much fun with it bone stock as possible.

also my hp goals im hoping for 250-275whp. nothing crazy just fun for the summer.

 

You already know there are a million threads about boosting the LS...then why aren't you able to find your answer out there amongst these other threads? I know this has been covered in detail 1000x before.

Your goals of 250-275whp are fine and as long as you build a quality setup, have reasonable goals, tune it professionally, and regularly service the engine, you shouldn't have any issues with longevity. Problems arise from over-stressing parts, but more often from laziness and bad maintenance

Poor mans gsr?
I know of a poor mans itr

 

yeah same meaning different names. its the first gen b16a head.
but i think that im just going to scrape up the money and get a gsr longblock from hmo..they are sold out of the ls engines anyways.

 

B16 head + gsr block = poor mans itr

Not sure what makes a poor mans gsr

Ls head + gsr block =.....nah that can't work

 

Depending on price, it might be cheaper to find a block locally and rebuild it for boost. You might be surprised how little it can cost if you're willing to put in the time and effort

 

Boost at 11psi

 

huh?

mod:
does anyone screen these post before theyre made from trial users?

 

The op asked what a stock ls can handle. I had a bone stock ls prior to my current car. I had the boost set and tuned at 11 psi with no problems. Im not entirely sure what was so mind boggling about my previous post but that is why I said boost at 11 psi.

 

No. They should.

 

 

your entire understanding with boost and whp.

 

11psi should bring him to his goal. I made 256 whp. What is off about my understanding with boost and whp? explain this to me so I can learn.

 

psi doesnt translate to whp

11psi doesnt = 150whp

a gt30 on 11psi is different on a gt28rs

real world example:
my setup on 10psi yeilds me 345whp

 

so u mean to tell me more boost dosent mean more power

 

No one of any experiences uses that direct correlation like that without knowing what turbocharger is used.

Here's an example.I could take a T25, be at 14psi, and make XXwhp. I turn it up to 17psi, and because of the fact that its efficiency range is maxed at 15psi anyway, increasing boost pressure would not yield more hp. It would just create more heat.

I do the same thing to a GT3076R, and I actually could make more power, but oops!!! I have a crappy intercooler.. More boost can't make more power because the intercooler can't exchange heat properly.

PSI means very little without knowing the turbocharger and efficiency range.

 

co-sign!

 

I already knew that different size turbos are going to have different air density due to having a cooler air charge if the size of the turbo is larger because it has less work to do. What I should have said is that 11 psi will bring him to his goal if hes running a gt3076 like I was running.

 

Yes. Being clearer would have made your point much more beneficial. Especially if the turbo you using as an example were stated.

I'm sure you'll do better with taking the additional time to type your point with a bit more resolve.



(Yes, I can be an ***, I get that already.. So save your time and keystrokes mentioning it, and Just move on, as now you know for next time.) Oh, and BTW, welcome to Honda-Tech.

 

Will do from now on and thanks

 

why not just get the poormans type whatever running and dont waste money on a different engine ?

Otherwise i can get you a really good deal on a gsr swap. motor has 6500 miles on it since rebuild with all OE parts.

 

Boosting a Stock Ls. I would built thebottom end before throwing boost at it.
Arp head studs, Upgraded crank, Pistons, Rods, and high performance head gasket.

 

What's wrong with the stock crank and head gasket?

 

He doesn't know. I can guarantee you he doesn't. Sounds like he's parroting something he's heard.
