Use stock rods with arp bolts.

Abos moved onto the k20 thread nowadays

Hey guys.

I've built a b20
84mm rs machine pistons
P72 head
brian crower stage2 na cams
double valve springs
1mm os valves
With 421 headers 2.25" exhaust
and dual runner maifold 3" intake it made 165whp
I swapped to tri y headers 2.5" exhaust and skunk2 manifold whale penis intake and it made 171whp but made less hp up to about 7k an the extra 7hp abouve 7k to 8600 =(

I've just ported the p72 intake manifold for a 68mm tb and going to swap it.

Was wondering if there is a better cam to better suit my engine.

Whats compression?

[Miniman_Alis]

Should be 12:1. Actual compression was 195psi across all 4

[Super-DA9]

was that cold or hot compression? Also where did you have it tuned just out of curiosity?

[Miniman_Alis]

Umm I dont remember.. probably cold and dry.

P28 S300 v2 ecu tuned by Rob Novak at my old work, CPWS in jimboomba. He does tuning 999 and definition? Motorsport as well.

[Miniman_Alis]

So do you guys think all these numbers are half decent? Would a different set of cams give me some better gains?

[Super-DA9]

Hmm tbh I would have thought those cams would be sufficient. By P72 manifold you mean vtir dual runner yeah?

Maybe consider swapping it out for a single runner IM to reduce restriction. Ask your tuner to play around with the cam timing if it has adjustable gears. Getting the timing right can make a massive difference with some cam applications.

He said he got junk2 mani already

[Miniman_Alis]

Yea dual runner manifold.
I did get a skunk2 pro intake and like I said it loses heaps down low. 27237

I ran a few different cam profiles thru Engine Analyzer virtual dyno (awesome program) and skunk2 tuner2 had a better power curve then the brian crower cams.

[Miniman_Alis]

On that dyno chart the red is the dual runner intake and the blue is the skunk2 intake.

[Super-DA9]

Was there seperate tunes done for each of them? Or just bolt on skunk2 manifold and test?

[Miniman_Alis]

Na new tune for new intake and exhaust.

[jdmTYPE R]

my lsvtec engine running 12.8 comp is making 225hp on skunk2 pro manifold

[Miniman_Alis]

Whats done to the head and what cams you running tho?

[jdmTYPE R]

its got alot of work done to the head ,pnp to the full valve train with sk2 pro 2 cams...im just saying the skunk 2 manifold works great so u shouldnt have a problem...

[lil_foy]

- whoops

[jdmEG5]

Hey guys, Sorry to revive an old thread..

I have a DC2 and wanting to do a b20 swap..

I have;
- B20b motor
- p72 head
- aftermarket cams and valve train
- vtec conversion kit
- breather set up
- golden eagle VRS kit (seals & gasket)
- arp headstuds
- arp rod bolts
pretty much all the main parts that is required
.. I just want to know who I can go to nowadays just to assemble the parts (assemble the long motor & refreshen up bottom end -rings and bearings)

I wont be doing anything spectacular...

[Miniman_Alis]

Read the how to build a reliable b20 thread and build it yourself.

If I had the tools and time, honestly i would do it..

[Miniman_Alis]

Where abouts are you?

[jdmEG5]

Where abouts are you?

Sydney, Liverpool metro

I've got a few quotes but it seemed way toooo much just to assemble everything together.. Maybe the fact because its a "B20VTEC rah rah rah"

[Miniman_Alis]

Its usually about 1-2k to machine and assemble.

[cbauto]

doesn't look like he's doing anything to the block. What would need machining?

[Miniman_Alis]

I would be putting bearings and arp bolts in it. And probably rings if i wanted to just slap it together.

[cbauto]

I would be putting in 13:1 compression pistons new rods and what's mentioned above if I wanted to just slap it together.

[jdmEG5]

I'll be replacing rings, bearings, machine the block..





So anyone knows who i can contact in sydney? Preferably a workshop with a license, no bodgy backyard shit

edit first post; I do have arp studs and rod bolts to go with it

[carayan]

needs more high comp pistons

[YLD-H22]

I have a b18b stroked to around 2L with darton sleeves ... Looking to rebuild it was thinking of going down the b18c 87.4 mm crank shaft as opposed to the 89 mm ls crank .... What is your thought on this change people ... I know id loss low down torque... It will run e85 and m24xx cams on supatech valves and springs

[jdmTYPE R]

Give jdmyard a call we do a lot of our own engine builds including my engine

[Blaze]

A lot of good information in this thread. Shame to see that it was buried.

[RenzokukenJ]

Where's bot

He might want this for tank buster

[u mad?]

Love the tags for this thread

My B20VTEC is still going hard, chopping commodores for days.

[EGBOY]

tried searching but does anyone have the measurments for b20 locating dowels?

going to machine some up..

the parts catalogue say 14x20 but why wouldn't you use vernier calipers or a micrometer?

[cbauto]

because it's easier getting an old grumpy fart like urself to do the legwork

[EGBOY]

because i dont have a dowell to measure with my verniers

[mocchi]

13.99mm OD

same as d/b series as well

u owe me a snack pack m8
