Hi, I have a 1996 Acura Integra GSR turbocharged. The performance shop that I took it to said that I couldn't boost past 10 PSI with the stock MAP sensor. I've searched the forums and browsed through sites and haven't been able to find anyone who's selling aftermarket MAP sensors. Can someone help me find a site where I can purchase a MAP sensor that is better than the stock one? Any help will be appreciated.

 

ive boosted 14psi with stock map ,only if you boost over 15psi you need diff map

a stock honda map sensor is limited to reading up to 11.2psi. dont bother with that hunk of junk missing link and stop recommending it.

 

if its limited to 11.2 psi then why did my boost gauge show 14psi and my map was stock even my bros si boosted 13psi stock my friends teg he boosted 12psi and has stock map so im curious why others say you cant boost over 10 on stock map when i did and others have. weird?

 

i wasnt recommending it, i just typed map sensor on ebay and saw it and thought it might work

 

3 bar map sensor

this is correct, you'll need to buy a 3 bar map sensor to boost any more than 11 lbs.

as for DOCHgarage, just because your gauge says 15 lbs doesn't exactly mean you're boostin 15 lbs, it is possible to boost more than 11 lbs on a stock map but it shoudln't read on the boost gauge if you were boosting that much. from my experience.

just check the FI (forced induction) classified here on honda-tech or google its not too hard to find.

good luck

 

first of all, the only stock parts in my engine bay are my map sensor, motor mounts, valve cover, and O2 sensors. Everything else is all aftermarket. Also, I'm running a full Dart engine(shortblock and head) and it's also Crome tuned.

I hate it how everyone thinks all engines are the same. Just because you boosted your's to 14 psi's stock doesn't mean i'll do what you did. 14 psi is not a safe way to run on a stock motor. Have you even gone to dyno your car? How do you know you're running 14 psi's? Boost gauges aren't accurate. Also, the highest boost I've seen on a stock GSR motor that is was considered safe is 12 psi. No performance shop will let your car run 14 psi's on a stock motor unless you tell them otherwise.

I trust the performance shops more than I trust people posting on the internet. I asked the performance shop for help, but they're busy and they haven't been able called me back so I'm resorting to the internet to get some guidance on purchasing an upgraded map sensor for my GSR.

Thanks for the help for the help everyone.

 

I also forgot to mention that i'm running a Full Race Stage 3 AC turbokit(w/Garrett GT40R instead of the GT35R). I would NEVER run this turbo on a stock motor. I had a RevHard turbo kit when I was running my stock motor and I fried my piston rings so I already learned my lesson. Don't make the same mistake that I made.

DOHC, I'd like to see you run 14 psi's on a Garrett GT40R with your stock motor. You make it seem that anyone can boost 14 psi's off of any turbocharger.

Good luck with that....The stock map reads 1.8bar or ~11.2psi (after removing the original 1atm)

I would check with Phearable and Xenocron. One of them should be able to get you one or at least hook you up with someone else who can...

 

BTW, just for the original posters info.....people use one of the following on almost every big turbo build

GM 3bar
Motorola 2.5bar
AEM 5bar.

 

i ment 14psi on stock MAP SENSOR my motor wasnt stock and was tuned on crome...etc

I'm well aware of that...and i will stick to what i said earlier. That's a stupid idea. I could care less if the engine is stock or not...boost pressure doesn't mean a thing...power kills engines; HOWEVER, since the stock MAP sensor only reads to 11.2psi, it stops compensating for boost beyond that point. Meaning it is going to run the same fuel and ignition maps for 11.2psi and EVERYTHING beyond that. Its going to run VERY lean at anything beyond 11.2psi. If you made it out with your engine still in one, healthy piece, then good for you. Its a stupid idea though

 

been running strong 3 years!!! but i dont boost 14 all da time
