i have a 1994 dc with a b18b.do you think i should convet it to vtec then boost or has anyone had success with a regular ls boosted minus vtec head...i heard non vtec ls on boost is slow but idk havent driven one yet...

there are ton of threads on peoples opinion on the matter......the search button will take you to them.

You dont need VTEC like that poster implies, but most do find it enjoyable.
good luck

 

no car that is properly boosted is slow by any means, some are faster some are slower, in teh case of LS or GSR there is not as big a difference once boost is applied

Lol yes there is. a vtec head and a non-vtec head at the same PSI. the vtec head will have more HP, as you add PSI the difference increases between the two. The difference stock is smaller than when boosted (140hp LS, 170hp GSR), only 30hp Difference. Add boost and it can go over 150hp difference.

 

yur not gonna see a 150hp difference at the same boost levels

i was talking about the difference in performance of NA C1's and B1's. which pale in comparison to either motor turboed

You were referring to them boosted.

B18C, 15psi pump - 445hp 310tq


LS - 15PSI pump gas - 350hp


100hp difference at only 15psi. If you keep going you can get 150hp+ difference.


Both cars were tuned by jeff evans. and I call atleast 100hp a BIG difference.

 

^ Unless the cars were tuned the same day, with identical turbos, and setups (minus the differences in head) the 2 dyno charts do little to nothing to convince me of the point you are trying to make.

It all comes down to the amount of air that you can move, I have seen a number of non-vtec motors that are very nice when boosted.

 

Highest HP LS on H-T - LS - 630whp/411ft lbs @ 28psi
Owned by 19sec Beast (he actually sold it, then whoever bought it put it on Ebay and it JUST sold again for 14,100)

Highest HP GSR(that I know of) on H-T - GSR - 792whp/610tq, 41psi c16
(Geoff Racier's civic .. hes the owner of Full-Race)
The engine was maxing out the c16 fuel and lifting the head from the block.

Of course it cant be exact.. Even if it was the same time in day, same setup. There would be something that could be said to discredit it. Anyway, it proves the point I was trying to make. I wasn't trying to write a textbook with the information, so there is no need to micro-analyze it.

The information he provided the OP was invalid and i was doing my best to show why in 10minutes. Lets not get into a debate about FI in the integra forum.. there will be too much invalid, inexpirienced information. We can in FI though

If we all desired to drive our cars on a dyno, that would be relevant. I firmly believe that a fun, fast, and reliable build can be had from boosting an LS. Mind you, that I own and drive a GS-R.

I absolutely respect your opinion, and honor that you are willing to actually discuss (rather than flame, or present false info). You provide proof of your beliefs, and stand by your opinion while honoring others. I am open for a discussion.

I agree with you 110%! I see no purpose in building a car than cannot keep traction where it is driven and for me that is the street.

I too own a gsr, mine was boosted making 300hp at 10psi. But i stretched 3 rods and bent a couple valves in less than a month it will be back on the street, fully built (everything but sleeves) going for 15psi. Should make around 400hp on pump and 450+ on race. can't wait.

On the other hand, my bro has a b18c 93 hatch, trying to push 700+hp. When it had 550hp it was undriveable on the street (on daily tires, got traction on slicks).

Imo, the most you can put down on a normal tire is 350hp. 400-500 needs a drag radial and on up needs a slick. (based on hondas only)

Yeah, the discussion of this dyno graph vs. this one is just impossible to prove and i understand that. but its a good representation. And for this discussion proves the purpose but if we were really getting down to it , you are right. There is no way to make my statement valid of 100hp more because of these two graphs.

 

i also respect your opinion on this, but as far as anyone would be able to say that GSR could be running a GT40 while the LS could have been running a small trim and a/r T3/T04E. switch the setups on the two motors and i would not be surprised to see the opposite occur +/- 20 or 30hp

also the peak hp numbers attained on either motor really means nothing because its all in the build, if enough money is spent the LS could reach the GSR's record

 

that massive power gain

True, its obvious the LS has a smaller turbo, as it is hitting full-spool faster. But a larger turbo would probably lose HP because of the lower redline on the LS and the flow of the head. The LS tiers off uptop more than the gsr
