Here is the story with this head.

I bought it from Stephanie Eggum (drag racing chic running T4 now, or at least i think she is) about two years ago. Some shop in New Jersey did the porting job on it. I didn't know who did it and I wanted to get some flow numbers on it before i put it on the block.







Here is what it flowed before Brad did any of the work..it is compared to a typical head that brad puts out, and a stock B16 head. There are no numbers posted but i printed the graph and counted it up, looks like the stock one flows about ~250ish, the one i have flowed ~270ish and an RLZ head flowed about ~290ish.



Brad decided that the exhaust valves were too big, they were 1mm over for the turbo car, so he said we should get some ferrea valves at .5mm over for intake and exhaust.

He said it needed a valve job since the previous one looked like it had been done with a stone (very old fashioned)

he replaces valve guides, reworked the combustion chambers a little and reworked the intake runners,

He said the exhaust runners looked fine to him

After all the work, here is the final flow. As you can see, old port job 271, new port job 295...im stoked



note the RLZ engraving









For now it is keeping the Crower springs and retainers that it came with, but I don't know the spring rates, if anyone knows, please help me out


I am going to be putting it in this car



which has this in it


^^ Brand new from Acura a B18c5 short block

which makes this much power currently



the current setup includes from top to bottom

Hondata s200
MSD 6al with cap and coil
ITR intake manifold
Si stock bore TB
Hondata IM gasket
Stock Si head
Brand New B18c5 short block from Acura
DTR 2.0 ltr GIFUCKINGNORMOUS header
crush bent 2.5" exhaust straigt thru with not resonator or cat to a 2.5" Mugen Twin loop
98 ITR 4.785 FD Quaife equipped tranny
ACT XT SS clutch
Comptech Cromoly 8 lb flywheel
Lenso VPD 13" and M&H 22X10 slicks

with that setup and a full interior and a half tank of gas it runs 14.1x @ 95x and 19.x 60'
it will do those numbers consistantly. im an ok driver and that's what it hits every time at the track

Stay tuned for the addition of cams, tuning, quarter mile times and Dyno sheets

Dave

Very nice . Who else can you go to to get 24cfm from reworking an already ported head

Brad and RLZ

 

RLZ

 

what cams are you going for?

ask brad about the RLZ 3's....worked great in my engine and a few other friends that i made buy them..haha

 

didn't even know he made a stage three

ill get ahold of him and see what he thinks

i was thinking rockets

or S2 Pro1

or BC3+

any more suggestions?

Dave

 

the 3's are big.

i ran them in my 2.1L and LOVED THEM. I ran the 2's in my stock ITR and they did DAMN good there as well....

i guess if you're staying with a stock C5 shortblock...the 2's would work pretty damn good.

 

can he run any of these big cams safely with .5 mm os valves. I am told in all my posts about this no. Am i missing something

 

those are some nice #'s....

 

That's some Master Jedi work there.

 

i will mic the piston to valve clearance before hand


Dave

 

Keep in mind Brad's flowbench reads a little lower than most. So the head probably flows even better than you think.

 

very nice and thanks for sharing

how do you test the pressures?

is it a tool or what?

i might see what someone around here can do as far as checking them


Dave

 

your Spring rates were 65lbs On the seat ..

215 lbs open @ 500 lift

and coil bind was like .510 lift

I wouldn't run a cam much bigger than 480 lift ..

on the intake ..

every head assembled gets checked

 

ok so that's a definate on the get new springs thing, thanks


Dave

 

I use a machine like this ..

I think they will be fine .. I wont run a cam bigger than 480 lift a on a street car anyways

rocker arms wear out to fast .. LMA binds ..

some skunk stage 2's or BC-4s would be good from what i have seen

 

ah ok...i was just checking specs for different cams


thanks

No problem man ..

I wish all my customers were like you ....

Waited Patiently for his head and didnt call me every 2 days asking if it was done

Nice flow numbers
I almost had an RLZ head once

 

What dragstrip were you at in the pics?

An engine builders Holy Grail!

Good work, Brad.

 

Good stuff, keep us updated.

 

I will do

Right now im looking for cams to put in it

Looking currently at

M22xx (or single x)

Skunk Pro 1

Jun II

Toda B

or BC3+


any opinions?

as soon as I get the cams ordered and in my posession I am taking it to Norris at Ultimate Performance in VA to tune it and then I'm going to find as many dyno's as possible to compare it to (so people can see how much dynos vary)

Dave

 

You know what I would recommend
