Is it possible to get B16's to push 300hp with major mods like the DRAG Gen 3 Turbo kit?
What kind of engine mods you think you'd have to do to keep it from blowing at higher psi?

Thanks

 

yes 300hp is possible, if u wanted to run high boost than u would need a sleeved block and built bottom end. plus a stand alone engine management system like dfi, speedpro, halltech or something like them would be a big plus for tuning.

 

Would I be better off with a B18? I thought about it... but I dunno if its gonna be worth the other 2 grand... Unless it has a much larger hp potential

 

Well of course it has a higher horse powr potential. Because of the diplacement.

Anyhow you will hit your goal of 300 horse power with the correct mods on a 1.8(lets say B18c, with T3/T4 turbo), easier then you would with a B16a. The Drag kits are wonderful kits, and with the amount of people who use them on this board could all vouge for me.

Bigger disp. equals more horse easier.

 

if u want to run high boost levels i would say anything over 1 bar (14.7 psi i think) would be high. with either motor your going to have to build it to run at higher boost levels, tuning is also very very important for a turbo'd motor, u probably could run higher boost on stock internals as long as your tuning is good otherwise u will break something. well if u get a 1st gen b16a than u could use the xtra money to build it. what car is this setup for? a 4th gen or crx?

 

Well, a friend of mine is trying to sell me a '91 CRX Si for dirt cheap. But I'm new to the import scene... I spent the passed few years with domestics, and my 89' Stang.

So... Looks like the B18 is the way to go. I saw a B18C complete changeover kit at http://www.hondamotorsonline.com/ ...... I was wondering how hard it would be getting it into the CRX, and if it's worth the money.
Or would it be easier/cheaper to build up the B16? I wanna eventually get 300+hp

either swap should be no prob, if it were me i would build a b16 cuz u can get the 1st gen b16a swaps cheap and i would use the extra money to build it up but thats just me, u could always get a stroker kit for the b16 and up your displacement that way, plus u get the benefit of a built bottom.

 

Simple:

Buy the B16a if the price is right and you don't already have a Bseries motor in your car.

Reason: The b16a comes with a decent tranny, good vtec head, decent intake manifold, ECU, axles, etc. You can always get a GSR or LS block to put in place of the 1.6 if you want more displacement. As for 300 (crank hp), there are many ways to go about building a turbo system, many which include high boost and the obvious need to strenghten the bottom end. If you plan on making 300+ hp, it doesn't matter what engine you purchase, you are going to end up tearing it apart and re-building it anyway. So buy whatever is in your budget.

HTH

 

"u could always get a stroker kit for the b16 and up your displacement that way, plus u get the benefit of a built bottom."

P.S. 1.6-1.8 stroker kit is the biggest waste of money imaginable when you can purcahse LS blocks for $150-$350.

 

If I already had a turbo installed.... Would replacing the block with a larger one cause any major problems? And where can I get an LS block from? Maybe I should put one in before turbo-ing it


Btw, thanks guys for the advice

hows it a waste? the way i look at it is that u get a built bottom and bigger displacement u don't have to go with a jun stroker kit or something that expensive, the guys who did l'natural's motor r & d racing (i think) can do the same or better for much less money. yes the ls block is cheap but he will end up building it anyways, u can get a first gen b16a just as cheap as an ls if not cheaper. he has said before that he wants to run high boost levels eventually which means built bottom. and there will be no probs with a turbo on any b-series it will just swap over to any b-series.

 

stroker kits can cost you alot of money, and throw your r/s ratio off...if u can find a stroker kit that keeps stock ratio then thats the ideal kit...but i still think a b20vtec 8k redline is the best

 

Slight correction ShaggenWaggon. Bigger displacement does not always mean more horsepower. I brought this up just a little while ago, and I guess I'll have to go over it again.

Compare the Prelude and the Integra Type-R. Prelude has 2.2L engine, ITR has 1.8L. Both have 195hp. The difference is in the torque. The Prelude is pumping out 156lbs at a relatively low 5250 RPM, while the ITR can only get 130lbs way up at 7000+ RPM.

Greater displacement most often means greater torque.

 

Comparing an H22 and a B18C5 is like apples & oranges. Compare a B18c5 and a B18c5 sleeved to 84.5 and then look at the torque and horsepower differences.

As for the matter at hand... stroker kits are way too expensive, you could build a sleeved LS block @ 2.0 liters that could handle 40 lbs of boost w/ aftermarket rods & pistons for the price of a good 1.6 to 1.8 stroker kit.

1.6L Stroker kits were developed for racing classes that do not allow the replacement of the block.

 

Tell me....just HOW is it like comparing apples and oranges? I'm VERY interested in hearing your explanation...

 

I believe that Myles Bautista ran 9.90 in a b16a powered turbo CRX and was pushing 450+ HP....

 

it is like apples and oranges for the same reason that comparing a Ford 302 and a Chevy 350 is. They are different engines built for different purposes. To accurately understand that more displacement will increase power you need to look at the diference between engines of the same design with different displacements. Like the stock bore and sleeved b18c5s mentioned, or something like a 302 and a 351 stroker. There truly is no displacement for displacement.

And dont say FI is a replacement, because boost will have more of an impact on a larger motor of the same design than on the smaller motor.

 

With a larger LS or GSR Block... What other major mods would have to be done to the B16a so it can handle over 300hp?

 

Well for one thing horsepower is just a function of torque and RPM anyway... Don't remember the equation exactly, but it's something like horsepower = (Torque x RPM) / 5250 or something like that.

And WHERE did you even get this from??? What would even make you think I would bring up FI? You're the first one who's said anything about it in the whole thread! I would shoot myself before I would say that ANY form of FI is a true replacement for displacement, cubes are cubes.

I'm not a person who has driven nothing but small displacement four bangers. I learned to drive on a 5.7L suburban. My first car had the Chrysler 360 in it, a 5.9L V8 (and I've had to tear that engine down and rebuild it). I know what torque is and what makes it.
