Turbo B16a VS Stroked B16a

wich would be faster you think

i think it could get close but end up on tranny gearing and tuning of the motor and of corse driver skill

I would go Na
just alot easyer to me to keep up espicaly if your driveing it every day

[SkyNex721]

When I think of NA I think of a B16a1, and when I think of FI I think of a B18b1. But that's just me.

Turbo would always be faster vs stroked motor, (same type motor). Turbo can be a daily driven car too, if built well and maintained properly. But I agree with you that NA motor would be easier to maintain.

Turbo, hands down. I dunno the best anyone has got out of an all motor B16A - I'd imagine that 220bhp might be cutting it close with a stroker kit, cams etc, but a turbo and intercooler and decompression means that a lot of boost can be dialled in.

[civickiller]

i heard that stroked motors arent that reliable. if you go NA the only thing you can do is up your comp ratio which means you gotta run higher octane gas, but with a turbo at 7psi you wont need to run as high of a octane gas

Ok about high octane gas. The highest compression that u can run 93-94 gas is 11:5 anything about 12 u'll need to run racing fuel. Oh setanta 220 is all u seen on an all motor? Well i've seen some that go 300 plus on fully built b16. Some guy around chicago is running 12's. He raced 4 turbocharged cars 3 which was civics and one dsm and he never lost a race. I'd say ppl that goes N/A gets more respect and in my opinion turbo is an easy way of goin fast and too many ppl have or getting turbo.




GOT BOOST?



HELL NO!!!

[Bleebdat]

The whole turbo NA is always laughable to me, properly tuned a turbo or supercharged car is just as reliable as any NA, the problem is people dont want to spend the time and the money to get their engine tuned correctly so they choose to go NA, but then the myth started that NA was somehow cooler. I dont get it, Ill take a turbo and more HP over respect from the rice kids in town anyday.

What??? Thats not true. What makes u say that? I'm goin N/A and i ALREADY PLANNED to get my car tuned. Any car thats not TUNED is gonna run like shit. I don't want my car running like shit. Oh theres a place that tunes cars for 200 bucks and it only takes him an hour to do it. Not to disrespect man but please don't go around and say "ppl wants to go N/A cause they don't want to spend time and money to get it tuned" cause that is not true. NOT all ppl with Forced Induction gets there car tuned or ppl with N/A. Even though i would recommend that they should.

Thats why I'm going NA all motor LSVTec! 300hp on an all motor and just doing 12's?...stock LS-turbo with upgraded injectors and clutch can do mid 11's and thats not even fully built. What Setana was probably saying is 220hp to the wheels add up to about 275-300hp...The motor I'm building has all type R internals (LS block, GSR head) 11.1 comp, I could go higher but want a daily driven, smog passing, pump gas running sleeper...Would probably beat some of the weak turbo and supercharged cars around...:flash:

And i do bow down to you!! Well i was told u can go 11:5:1 on pump gas? Thats what i'm gonna do. I was really thinkin of doin that b20 v-tec but i'm not sure though. Rite now i'm lookin for b20 bare block

[EF_LSVtec]

I was going to get a B20 too, but didnt want to gamble on aftermarket pistons and risk not passing emissions. I figure since Type R parts are all stock, then it should do ok on smog control...I didnt even go jdm pistons and went for us type R. Only worry is my cylinder head's ported and 70mm throttlebody...I dont remember my total comp., maybe just below 12 like you said, 11.5...I went to my speedshop last week and he's just waiting for the rod and main bearings. 3 more weeks he said and it'll be "judgement day"...not to count breaking it in for 1000 miles.:flash:

[Setanta]

Actually, I read the question as a modified B16A, not as LS-VTEC etc as they are no-longer a B16A, simply a head.

Reliably, all the B16A's with no stroker, original block etc seem to produce 220bhp tops in NA format (one of them ran a stroker crank). NA B18s seem to be the engine of choice for racing though.

The reason for that is that we seem to have a lot more turbocharging of NA cars to produce our power - it's cheap and efficient and everyone has the cars fully tuned and setup on dynos (which are plentiful and reasonably inexpensive). Aftermarket programmable ECUs are relatively inexpensive - some are even designed and built here.

Aussie philosophy of car tuning seems to be that NA is for track cars and in the majority, turbo 4s, 6s and 8s are the way to go for 1/4 mile racing to be competetive - probably asisted by the fact that imports from Japan are on the rise and a complete front cut from the seats forward makes for easy transplants/hybrids.

Other reason? Honda's are in a minority in Australia. We get a reasonable amount, but there are better cars to buy for the money Honda wants (ouch - that hurt to say ).

[emil13si]

Can I ask one question(for you it would look like stupid one) what does NA mean-stands for...I know what means supercaharged or turbocharged but I don't have a clue what does NA mean...

Is that when you replace all things in your engine(pistons,polish head and lowering it, itc) or is that something else

Thnx for all your answers :silly2:

Naturally Aspirated. means the car does not have any type of forced induction.

[civickiller]

hey ef_lsvtec, correct me if am wrong but a lsvtec with type r rods and pistons with a gsr head will yield a higher comp ratio than 11:1. more like 12:1 or higher, probably higher.
