hey... what do you have on the motor? builds...

 

awesome info guys... now lets say there's a bit of a budget... say.... $2500 ... what direction would most of you go with a budget like that... or is that enough to go ls/vtec, b18b, and b16 ... [Note] I'm not saying that budget is for the turbo as well, just the motor to get me up and going.... thanks

 

JHU EH2 - If you're building the motor. . . . disregard all that bs about the "weak rod bolts" and the long geared tranny, blah blah wah wah. The rod bolts are replaceable - a no brainer if you're building your motor, and the tranny is just fine.

It has to be a longer geared tranny -

The LS, even with a built valvetrain is going to be risky to run over 8,000 rpm. . . with that low of a rev-limit on an LS, with a gs-r tranny - you'd be shifting into 5th. . . . unless you want to run large rims at the track. Not to mention that the LS in turbo fashion puts out a buttload of torque, and the longer gears will ease a tiny bit of your traction woes.

There's nothing wrong with a well built LS motor.

With a ported LS head and valvetrain to support higher rpms. You can rev higher - and make power.

Don't believe me?! Here's a dyno chart for ya. . . the top one is in fact an LS despite what it may appear to be from the rpm's this motor was turning. Just look at that torque. . . b e a s t



Here's another one



Both charts are at 26 PSI.

Do your reading, take peoples opinions seriously, but not to heart - and above all, in the end you should make your own decisions.

With the GSR you will make more horsepower
With the LS you will make more torque.

The LS build will cost you significantly less.

Both motors are capable of doing what it looks like you want, so if this isn't going to be a ***** to the walls all out race car, then do whatever makes you happy.

B18a/b
B18c

 

thanks DragSource... this'll help tremendously on my decision... ... yeah i'll be doing more and more research and all the possible directions in boosting... i just wanted to start with H-T members' inputs first.. that way i can have more specific topics to search on besides "best motor to boost".... thanks all

 

with $2500... you can't even buy a b18c. ah... but you can get a complete b18b turbo on a budget. get a b18b. if you're unhappy, slap on a b16 head later on down the line.

 

I'd go with the b18a simply because with that budget you could probobly have 2 spare motors.

 

Is your budget $2500 for just the motor? You could probably find a GSR for that, if you can't find a GSR for that much, wait a few weeks until your next paycheck and buy one... it will be worth the wait. If you don't want to wait, get a B16 swap.

Why does everybody always talk about torque? Just because you make a shitload of torque doesn't mean your car will be fast. Hondas are little 4 cylinder FWD cars with dinky tires, their not RWD V8's with fatty tires... so traction is limited already. **** I only have like 180 ft/lbs and I can't get traction without my drag radials on and I also have an LSD. The turbo will give you plenty of torque, but if you need more you can always swap a 1.8L block in later. Too much torque too soon = wheel spin... so don't even worry about the torque of the LS. The powerband on those dyno charts "DragSource" posted look like ***... that torqe spikes and drops off like a rock. I prefer to carry power/torque as high as possible... I want lots of topend power. This is good thread that explains what I am talking about... http://www.importbuilders.com/turbosetup.html

Oh and long geared tranny's do suck ***, they make your car accelerate slower... this thread explains everything... http://www.evans-tuning.com/viewtopic.php?t=1496 If you have traction problems work on other things like LSD, tires, traction bars, staged boost controller, etc...

 

So in a non-vtec b series motor, you'd rather shift into 5th gear than run an LS tranny?

 

IMO b16 and b18c motors are the best for boost. Proven time after time.

I wouldn't run a non-vtec b-series motor in the first place.

 

Yeah, you just stick to your D16

 

I will...

 

I know I'm just jumping in but oh well,

I have been searching for awhile
I'm planning on getting an ls, Importing an ls or rebuilding the current motor,
I'm not planning for 500whp or anything,
But my queston is,
Can a B18B stand 200-250WHP on stock internals?

I'm a newb and thats why I'm asking questions

 

The LS might make more torque, but the torque falls of rather quickly on most LS setups. Once peak torque is made it starts to drop pretty drastically. The torque is usually never carried over to redline line a B-series VTEC motor.

Now a LS/VTEC, that's a different story.

 

I'd take a turbo b16 anyday over a turbo b18b. You don't build a honda for low end and mid range.

Heres a dyno of my old b16. I thought the tq curve was pretty decent. (car trapped 121mph in a del sol )

No problem. Tuning is key. You'll be very happy w/ it. I'm wondering if any of the LS haters in here have ever even owned one?

Wondering the same thing myself. . .

Lots of hateraid drinkers.

Pretty soon all of us will be hating TQ. and HP. and buying D16z6's to Turbocharge. : As Pig's fly overhead :
