sr20det reliability

[Logan76]

Not only would 20PSI through the SR T25 be about 5 PSI past its effeiciency range, but its not as much the fact that you ran 20psi on a T25, oh well you risk blowing some hot air or grenading your turbo, but you would've leaned out your mixture to an extreme point, especially if you didnt have any tuning, so thats how you smoke your motor.

well i didnt feel like reaeding EVERYONES comments so...

The KA is not as reliable simply cause its not a motor designed for boost. With upgraded internal parts it could be a good motor but stuck its not a smart move.

On a friends turbo KA he had basically melted the pistons rings so the compression went to hell and it was not doing so good. I threw a rod in one of my cars and it was NA. Another KA developed rod knock.

I havnt had the best of luck with KA's but if u treat them nice they will last. I dont treat motors right AT ALL!

I like the SR cause stock it can make ALOT of power with minor upgrades. I wouldnt go more than 12psi on the stock turbo cause thats what im running and you can feel that after about 10 psi it simply dies out.

Ive got friends running lower 300hp range on stock internals, stock manifold, a fmic, and a larger turbo. They run great and reliable and are driven dayly.... and abused dayly.

To get an idea how strong the SR is. Last summer i did 28 Drag Runs down Cecil County @ 16-20psi with ZERO engine problems. All using the 2871R .64 or .86 Turbo. I use the car to race on track and street. Gets abused every weekend from Drag Runs to Highspeed Sprints. Ive had few issues that was my doing such as running cheap IC piping and would blow couplers alot. Fouled plugs. Forgot to attach my wastegate line once. Which was insane. Hit 26psi on the 2871R and no knock occured. Just a loud pop from an IC Coupler. Still using stock headgasket, stock internals, stock valvetrain besides HKS 264 Step 1 Cams. Honestly there are more SR's everyday pushing 400whp on stock internals then KA's. I like the KA though. Its like a V8 with its torque and response.

Thanks for all the input, this thread rocks

anyways, I made a parallel thread on the KA-t thread about how many motors they have blown to help weigh my decision on both motors

zerothread/226700

It seems that KA's need a LOT more know how and work to get it reliable, but it can be done. the SR's are no different, its all about the tune.

I just want to see you SR guys input on the parallel thread

Seems like the #3 piston and rod have the most trouble.... hum

Anyways. I think the KA is pretty cool to boost cause the torque and power u can make. It is alittle bigger displacement too so you do get alittle more power it seems like.

I dont liek them cause im really hard on my cars and if you rev a KA high your more than likely to break something.

Just looking at the other page you started reminds me of why I got away from the KA. I was thinking of going KA-T in another car but on second thought ill pass. I dont want to have to deal with blowing another motor.

i am meeting both engines in the middle.

s14 sr20det sleeved and bored to 90mm for 2.2Llong runners, vtc, 9:1 CR, and a 4.36 gear ratio for torquestep 2 cams, RAS, valve springs and retainers, balanced crank, and short stroke for revs

top it off with a gt2876r .86 (for now, might sell it and go topmount)

best of both worlds

hey if u idiots dont belive me on 20 psi on stock t25 then just go pull off the vacume hose of the wastegate and let it hang, go for a test drive and have fun. if its cold weather it will go 20-23 psi. it the weather and humidity is warm then it will go 16-18psi. and no the turbo did not grenade right away, its all a myth. turbo lasted me 4 months before it totally blew the **** up and i got on the car everyday at least 4-6 times a day. and on 20psi it runs almost as fast as a gt28rs on 15psi.

[cheapscheisst]

good god so that's what you did? did it ever occur to you that there is a reason why everyone DOESN'T do that?

[Logan76]

Wow your stupider than you made yourself look, you didnt even use a boost controller? gah uncontrolled boost is gay. and your dumb.

Reason you blew your car was because your blowing insanely hot air into the motor. It causes detonation and everything goes to ****. You do realize the T25 wont hold 20psi past 6000rpm right. It cant even hold 14psi past 6000rpm. You may think its faster just because you get the initial feel of torque but in the end its not making more than 250hp. Your also doing this on stock injectors and MAF too i imagine. Maxing the MAF Voltage and Injector cycle will make the car run nice and lean blowing your **** to pieces. IGNORANCE at its finest.

[cheapscheisst]

and, let me guess... you also ran that jerry-rig on your stock ecu... and now you think the sr is an unreliable engine...

blah blah blah, i guess now i realize y i stopped coming to nico, nothing but a bunch of stupid idiotic ****ing morons on here. all in all sr20det's and ka24de's are junk . period , case ****ing closed. if u dont like it then **** you. have a nice day

well that was value added now wasn't it?

[ILikeMy240sx]

wow... sounds like someone woke up on the wrong side of the bed. Chill out dude.

T-25 and 25 psi is possible, yes. And I believe you when you say you ran 25 psi on your T-25.

Now, whether that is a good idea or not is another issue. Running that much boost on a small turbo that is struggling so much to push more air even at 14 psi is asking for trouble. At that point, not only are you compressing air to raise temperature, your turbo is working way beyond its limit and adding additional heat to it which equates into your turbo being a very inefficient heat pump. This will stress out your turbo and increase your intake temp to dangerous levels.

I really would not do this on my motor.

Anyways, it is a good news that you are leaving this forum tho... because that means NICO will have less of noobie posts like yours filled with idiotic statements.

Thank you and good bye.

That right there proves my point how ignorance destroys engines.

In all of that ownage I'm actually sad. Those 2 dead SR's could have gone to people who could appreciate them and bring out their potential.

[DrifterProdigy85]

I feel the same. I remember a guy on 240sxforums posting how he blew his SR up just because he was getting an RB20. Held it at rev limiter untill a rocker came off. Pure stupidity.

If anyone links me to a thread where you say anything like this again you're getting beat with the BAN stick. You got caught talking mad trash. Be a man an admit you have no idea about the SR or turbo's in general. Flooding the internet with idiocy should be a crime. We should all have to plug into the computer so we recieve an immediate and lethal shock upon posting suck complete and total BS.

With that out of the way

The SR is a well designed motor. The KA is also a well designed motor. Both have been proven to make very good amounts of power. Most people don't realize how much 300WHP actually is in a 2800lb car. Either engine can make 300 without a problem. Both require basically the same exact thing, add boost, tune fuel and ignition...done.

As with every other SR / KA comparison, things often come out very close to equal. It boils down to what the individual wants. Neither the KAT or SR is new anymore. I can't swing a dead cat without hitting a SR powered 240. The KAT is not to far behind.

This thread has alot of inaccuracies in it. If you're new, please don't use this thread as a baseline for your decisions. In the end, you need to be non partial to have a true opinion.
