Im not really firmiliar with the b series ive oosted a d series and it was pretty reliable how much hp can you make with the motor and can it still retain reliablity?

its a b18b1 out of a 96 integra

 

anyone?

 

every1 will give you diferent opinions. id say an LS can take about 220 - 240hp on stock internals. ask in the forced induction forum, they probably know more details.

 

i dont know about that......... ive seen an ls on a honda tuning mag...... and it had more than 500 hp to the wheels!!!!!! but for power like that your goin to need alot of supporting mods.

 

That's the same question my buddy asking me...

 

well im gonna build the motor completely so im just wonder what these motors can do. im gonna be putting a gt35r turbo on it.

 

good idea.....^^^^

 

There is no possible way a stock LS will make 500hp and last for more than a few days. That motor must have been completely rebuilt from oil pan to valve cover.

A GT35 will give you nice peak numbers, but the lag will suck for a daily driven car.

x2

 

if you have the right tune it should be just fine.

 

im sorry but no tune will help you if you try to get 500hp out of a stock LS. yes they can get those numbers but it would have to be a complete rebuild of the block, head, and tranny. and youd be looking at a few thousand in parts and machine work alone.

 

we tuned a bone stock ls (aside from custom grind cams) that made 407whp at 26 psi from a sc61. the motor ran on that setup for about 6 months and the motor is still running in a guys car to this day... my ls makes over 600whp at stock sleeve stock stroke. made 500.76 on just 27 psi. we have since put a 75 shot on it and turned the boost up.

a stock b series transmission is good til around 700whp.

a tune is the most important part of any build. with a good tune and a person driving with a freakin head on their shoulders(very hard to find these days) motors WILL last.

 

^^^ as a DD car?

 

I'm not trying to call you out, but I don't believe that motor survived like that...not without seeing it with my own eyes. Headbolts? Sleeves?

I totally believe that a bone stock 407whp 4-cylinder will last if you aren't shifting above 4000rpm, but then what's the point of having the power in the first place? You make it sound like the motor has to be babied to last longer than a few days, and when you are spending a ton of money on turbo parts, why not build the thing properly to ensure reliability? Talk to guys in the FI forum, and I bet none will recommend running that kind of power on stock internals.

 

i'll have to reload the video we made for it to streetfire and send you a link. it was taken off of youtube because we used slipknot music in it and some copyright bs they made us take it off. the car was taken to the 1/8th mile numerous times and street raced numerous times. ran 7.20's in the 1/8 with 22in slicks.

and im sure they wouldn't reccommend that... but it wasnt any loss to anyone of anything went wrong. just a idea and it worked.... people need to learn to think outside the box and outside the realm of what others say you can't do... everyone told me all my work was going to go to hell cause i had stock sleeves... motor made over 600 and is still in perfect condition. perfect compression readings, leakdown tested all good... motor is coming out of my car and going into a friends to be detuned to about 400 and daily driven.

look in my garage for the specs on my personal track car. stock bore, stock sleeve ls motor everything else is completely built though.

the motor was used as a dd car after all the turbo stuff and cams came out. but while it was making 407 it was a weekend warrior kind of thing. but we romped the **** out of it.

 

it was a straight ls motor no gsr head on it?

Also what type of pistons do you guys run in these Je pistons and crower rods? What would be a nice set of cams and cam gears?

Sorry dont know much about b series just getting into it since i just sold my built sohc.

 

both my 600+ and the stock 407hp one were straight ls motors... go to my garage for specs on my ls. the 407 was bone stock aside from custom grind cams (same ones as in my civic).

crower or manley rods. wiseco or je for pistons.

crower makes the only decent production cams i know of for ls.

 

1. The stock LS will handle 300whp safely with a good tune and quality parts.
2. 600whp on a stock block is possible, but not necessarily the smartest idea for reliability's sake
3. Don't just jump into thinking the GT35r is the turbo for you. It's kind of the "trendy" turbo to have, but not necessarily the best for everyone's goals. People misunderstand the function of ball bearing CHRA turbos...that's a story for another day.
4. If you want more info, go to the Forced Induction forum. You'll get better and more consistant answers
