"The b18b's power drops off at 6800"
 

Mine wont...
The beginnings of 8000rpm LS head

I paid $310 shipped for the set. I could only get them at this price by showing the dealer GE's cost of $315 shipped...He wouldnt do 300 :o






And here's where theyre going


Cams will be Crowers 403 N/A cams. Ive seen dyno plots of people using the 404 strip cams, but I dont want a lumpy idle. The 403 cams will have a bit of lope to them, but I'll just turn the idle screw open so it sits around 1000. She will then spin happily to 8000 :)
I could take it further, if the rods werent rated for only 8500...
Before they go in, Im taking the head to a local shop and having a mild port/polish done just to smooth it out and take advantage of the valvetrain.

The block is in the shop right now, getting the cylinders honed and bored, .003, for the wiseco flat tops, helicoil'd for 2 damn stripped mount holes, and the blockguard installed (yes, pressed and welded in 1/4" down).

wow..i have no idea what this entire thread meant lmao

nice, i want to see pics of install and dyno numbers.

wow badass motor man.

thats awsome, I want to start a project like that too

those look good as hell. what are the specs on the cams that you intend to buy ?

*Deliverance Voice* You sure do got a perdy cover boy.:D

Specs on the cams are
"Advertised Duration":
264/264
Duration @ .050":
221/220
Gross lift @ .075":
422/411

Stock is (234/236) (194/196) (395/380), respectively.

Seems like a lot for turbo, but Ive seen this is the way to go :yes:



I love gooooooold :D

Sounds like it'll be a beast once its done.

Well, Im only hoping for around 140whp before turbo.
I really doubt I'll dyno it before I tune for boost...just seems like a waste of time and money to me. I dont know though...we'll see. Maybe some special dyno day will happen and I can get a deal

sweeeet!!!!!! sounds like an awesome project!

yeah, once i finish the body work on my car i will go with a pyr chip, delta cams regrounds and crower dual springs. should boost the power up a bit. ohh and next year a l10 torque converter.

good price. You got valves yet?

Im really happy that this project is moving along at a steady pace...not exactly speedy, but steady:rolleyes:

I wont be using SS valves, because I dont want to change out the guides for bronze. Plus, the head only had around 60k miles on it and theyre in good shape. Down the road I might, but I dont think anytime soon.

As soon as I shell out the fat wad for the gsr tranny, it will be ready to go in. I might just wait until next spring to do that - Im not swapping over the winter

why going with a GSR tranny?

ls gearing is waaay too long for what Im building
b16 is too short for highway driving
gsr is just right w/ 2 long and 3 medium

are the stock valves light enough to hit 8K?

I dont see why not

:banana:

Found a hydro LS 5th set!

Now I could get that b16 tranny and do highway without going nuts! YAY

what RPM do you think a stock b16 tranny would turn on the highway anway? any ideas what you'll turn now?

4000+ at 80
Should be just over 3000, at the same speeds, but Ive never been in an ls on the highway to know for sure.

mine is at 3500 @70mph but it is an auto. i would imagine the manuals would be a bit lower.

see i would think it would be the other way around becuause usually they put taller ratios in to compensate for that.

So if the Si trans turns about 4k @80, i'm assuming it does the same on a stock Si? Shit is short. thought mine was bad

yeah, the b16 is nuts for ratios
Ive always heard the manual ls is really tall (taller than auto)

thats what Ive heard too.

you can use this to find out exactly what RPM's you'll be at:
http://nonsense.netfirms.com/speed.html

the prelude is at just under 4k rpms @ 80mph, i need a Prelude S 5th gear so I can cruise at around 3350rpms.

yeah i wish the preludes would be a little lower... when i wana cruse at 85 or 90(florida highways people haul ass) im getting close to 5200.. and that cant be saving fuel

what i'd really like is an AccordR 1-4th and a prelude S 5th, that with a quaife would be sick.

80mph @ 3500RPM.

THat's gonna be a bad ass set-up man. I'm glad to see you are doing it right the first time Pat. Cam profile has always been a mystery to me cuz I see so many people making more power on N/A cams applied on turbo set-up. I'm using JDM ITR cams for mine. I've seen people make more power on CTR cams that actual aftermarket turbo cams.....
