Im in the process of putting together a turbo setup for my B18B1 and im wondering what would be the best way to hold the power steady to go above 6200-6500rpm up to like 7500. What would help me out without hurting the tq that most stock B18B1's make when turbo'd. I was thinking of upgrading the valvetrain, maybe some cams and port and polish the head. Also thinking that balancing the crank would be a good idea and maybe some forged pistons?

I am looking for around 300whp on the stock block but if i build it slightly ill be aiming for more.

 

I have b18b turbo currently boosting 9 pounds of boost dynoed at 242 at the wheels u should be ok how much milleage that the motor has? U could take it up only to 7000k safety

 

i think 7200 is the max for the LS without upgrades... i shift at 7 myself.. no point in going higher with LS cams since there is no power up there.. i've gone to 7500 on mine cause of a 2-3 miss.. but wouldn't reccomend it..

 

U probably need a block guard and a 370 cc injectors and a safc or even better a hondata s200b

 

the setup will be a super 60 Tc, tubular EL manifold, 3" downpipe, 2.5" IC piping, 550 or bigger injectors.

Basically i see that most ls-t's drop the power band at like 6K-6.5K and im wondering what the best way to hold the power up to 7.5K. Also build the engine so it will handle 7.5K. I know the cams arent the best and it would be smart to balance the crank. Im just wondering if new better springs, retainers, valves etc would be wise.

 

if your looking for more power higher.. your going to need better cams/more flow.. unless you want to go LS/Vtec

 

i just want the engine to be able to rev to 7500 reliably. Dont wanna go the ls/vtec route and i dont wanna lose any low-end.

upgrading the vavle train and maybe some crower turbo cams would be a good start right?

 

I'd invest in some ARP rod bolts and head studs before I went throwing on new springs and retainers and all that crap. You don't NEED to rev to 7500 to make power on an LS-T, so why try to? ARP's + good tune = have fun.

Yep, you should be good to go after that.

 

im just thinking there is more potential in an LS block but maybe im completely wrong.

I was thinking
-crower valvetrain
-crower cams
-ARP rod bolts

The car is pretty much a street/freeway car so im just looking for ways to maybe extend the power band or even if i could just reinforce the low to mid range tq that would be awesome.

 

If you want to build an LS but dont want to convert to LS-Vtec then revving high is not an option, yes some people built their head so it capable of handling high rpm but no matter what an LS head will never flow like a Vtec head in the high rpm. 300whp is easily achievable on stock ls head and bottom end with piston+rod for peace of mind, you dont need to be revving to 8k to make power.

If you shift the power higher into the RPM band you sacrifice mid/low end torque. If you shift the power band to make more low/mid range torque, you lose top end power. Make up your mind.

Gear ShiftRPM Speed @ 7000 RPM
1st N/A 34.9
2nd 4118 59.3
3rd 4675 88.9
4th 5329 116.7
5th 5174 157.9

7000 redline, 23.1" tire, LS trans. If you think you need more than 160 MPH of potential, what the hell is wrong with you.

 

anything i can do to improve the powerband? What do you think about this setup http://www.kteller.com/store/p...d/646 seems pretty inexpensive and seems like it could only help.

What piston/rod combo's are good for turbo ls's?

 

im just greedy and wanna go as fast as possible, btw i have a GSR tranny so its slightly different.

 

i have a modified ITR intake manifold that will fit the LS/non-VTEC head. it deffinatly helps the powerband up in the upper RPM range and would deffinatly shift your peak power closer to or over 7000rpm even with the stock cams.

its currently for sale allong with a set of crower 403 cams (which have been proven to work well with boost also) if you are interested. PM me for more info.

 

im guessing this will shift the powerband up and hurt my low and mid-range power/tq?

Any opinions on the RM cams, retainers and springs?

 

dc2 boost what set up are u running? what turbo mainly

accually it wont hurt your low-midrange power much at all. its a pretty nice upgrade for the LS engine.

very solid right here. to help out a little more you might want to look into a different intake manifold, such as blox or perhaps even just a b16 mani (ive heard some things from a few people about the skunk unit fitting poorly). that right there should be solid to 7500 rpms. what turbine a/r are you running? a .48 might choke out up there.

oh, nice choice on the gsr trans and b18b motor, ive got the same setup which will be boosted in the next few months

 

yeah i was thinking IM down the road and maybe a slightly larger throttle body. I dont wanna get too deep into the engine because if im gonna build it partly ill wanna do everything and run HIGH hp. How many companies make IM's for B18B's?

As for the turbo im gonna run a .63ar, i havent found alot of info on the super 60 T3 but i believe i can get it in a .63ar or atleast i hope. Only thing concerning me is i would like to have an external WG so im not sure what to do. Any advice on that or maybe there is a turbo very similar thats not internally gated?

I am very happy right now with the B18B1 and gsr trans combo. its in my 92 cx hatch right now which is a pretty light car and it pulls hard, especiall with my stage 3 clutchmasters clutch and 11lb flywheel. The motor will be going in a 98 EK which is considerably heavier and also will have a full system and alot of other stuff so i wont be as fast as i could be in my hatch but i wanna build the coupe completely.

Whats ur setup for ur B18b consist of?

you can find that turbo, my friend has it on his g60 turbo jetta, internal gate and .63 turbine.

my setup right now is a b18b, i/e with gsr trans, act hd pp and 6 puck race disc with hasport mounts in a 97 hx coupe. as far as turbo goes...well i bought an intercooler the other day which is a start . not sure what manifold im going to run but i will be using a t3/t4 57 trim with .63 a/r on the turbine self tuned on uberdata, i just have to find the parts i need when i have money in hand.

 

Cams are the weak link.

Rod bolts, pointless as the Honda rod doesn't break at the bolts.

Spin balancing the crank, pointless as the LS already has a pretty good balance on it - unlike all F/H series except H22 and F20B/C, for example.

 

so u think cams, retainers and springs would be a good upgrade?

 

yes new valve springs would be a wise investment.
