built and semi built?? and some help please

[Punisha00]

Hi guys, i have seen the terms built and semi built engines could anyone give me a quick def on them?
Also as per my old thread i have bought myself a b16a (EG6) engine and going on worst case want to run 20psi on this engine with no problems, can anyone throw there 2 cents in on what has to be done to the engine? And will the gearbox and lsd handle it?
Recommendation on stand alone ECU? haltech E8??
any help please. thanks guys

All you need is rods and pistons to handle 20psi.

Stock gearbox and lsd will handle it fine.

Find your tuner before ECU.

20psi on a TO4Z or a GT28RS?

OH wait never mind, it's all the same right? :zip:

[Lukezen27]

Why so much boost?

These motors can make big power with only 15psi once built and then there's the problem of getting the power down to the ground.

If you really want big power maybe you should look at getting a B18 or B20 bottom end for displacement from more toque

Just buy this one pre-built

NOPE

[trism]

i dont like how the term "built" and all its derivations "fully built, semi built" get thrown around

but generally, when someone is talking about a "fully built" motor it means rods, pistons and generally the cams/valves/valve springs etc have all been changed

if its only "semi built" it might mean only the head has aftermarket parts or all it has is rods and pistons

all good and well getting rods and pistons,
how long will your stock honda sleeves last on 20psi though?

NOPE

well i want 350whp and i m guessing i can make that with no more then 20psi and if it is less then that just means my engine will be able to handle it for alot longer. upgrading to a b18 or b20 is not an option. i was lookin at running a SPA cast iron manifold with a Garrett T3/T4E 57 trim compressor and they gave me an option of .48, .63 and .82 turbine A/R, and thoughts?

i found a place that tunes haltech ecus but dont specialist in hondas does this matter?

Big turbo but I guess your after big numbers..

I'd say a Garrett GT30 or GT32 with ether a .82 or .86 rear

Not sure the cast iron manifold is going to cut it... it may be able to handle 20psi but the added heat your adding to push that amount of boost through a badly flowing cast iron manifold is a motor killer right there..

So upgrade with forged components and it!

Hondata S300 or higher
Con Rods
Pistons
Race Bearing
Sleeve the block (might as well whole the motors apart) bullet proof that sucker..
Hight flow oil pump
Oil pan baffle
Oil Cooler
Bigger Better radiator

The list goes on lol

Yes that matters big time mate

Turbo Honda's are very sensitive to tuning!
You don't want any non Honda guys touching your motor..

Theses motors are not big low com engine that are forgiving to tune and can handle a bad tune here and there!!

[Limbo]

for that type of power speak to someone who knows honda motors.
350hpatw is alot for a b16

F22B1 engine swap from accord :p lol

I'm going to do a rebuild soon and parts i'm going to replace (and hopefully hit 300whp) are:

Cylinder - stock sleeve
Piston - Arias 8.2:1CR forged
Conrod - H beam Bisimoto, ARP bolts
Bearing - ACL race full engine bearing kit
Port and Polish
Dual Valve spring and titanium retainers
6 puck act clutch
12lbs 'LSD brand' flywheel
Cams - may be turbo regrind
Cam gear - Bisimoto adjustible cam gear (if i do work on the cams)
Greddy or honda OEM timing belt
OBX LSD

I don't know yet but I'm planning to run AEM F/IC piggyback on my accord coz it's an OBD2 and i want to retain most of the vehicles features. (anyone heard or had any experience with aem fic i.e. their tuning capability etc please PM :D:D:D:D)

[Bludger]

depends what you wanna achieve mate.

can't just say i wanna run 20 pound boost.

thats just stupid.

Set a goal and then work out whats the best way to achieve that goal.

Why send all the cash and get a crappy OBX LSD?

[Slaz]

Why send all the cash and get a crappy OBX LSD?

cause they aint so crap, if you get a good one, they have been known to have a few that arnt the best, best measure bearing areas and runout on it prior to install so you know.

Na mate there crap

Get something better

I've seem 3 times the charm before getting a good one or more

I've got an MFactory one just installed...

I'll let you know how she goes

[Benson]

A long time.

Good one!

But yeh Honda sleeves are pretty strong if you tuner knows how to tune them properly. Didnt 90POV make close to 300kw with stock sleeves? :thumbsup:

I dont have a problem with my OBX LSD, if you are not talking from first hand experience I think you should stfu :thumbsup:

No not me personally but a mate had to have his replaced 3 times on his turbo D so why don't you STFU yourself mate!

MFactory LSD are only slightly more and much better quality from what I've heard and read and seen in person!

I’m yet to test this as my first drive is tomorrow and I can’t go hard while I’m running in my new HD clutch.

i've seen both OBX and MFactory and MFactory quality looks so much better-- here's mine below

i heard that Mfactory and OBX LSDs are pretty much identical. Just different branding

I didnt want to be the one to say it, but thats what it looks like to me :zip:

Nope made with different quality steel and Mfactory are there own design but OBX are copys for quadfire and what the name is

[Limbo]

that's not wat a mutual friend told me

hmm I think we are talking about the same friend and that's what he told me :p

Might call him and ask lol

[Limbo]

ask him if 440cc injectors r still ok or not

[Lukezen27]

lol don't you have 440CC already?

Small Clarification on the MFactory LSD

The MFactory unit is NOT a reverse engineer of Quaife or OBX, neither are these made by the same manufacturer.

We have our gears manufactured to our specifications and we apply our own high standards to its manufacture as a result, our finishing and tolerances are much better than OBX and competitors albeit still managing to offer at a competitive price.

MFactory LSD are fast gaining popularity in the US because of Competitive pricing and High Quality.

"Gain a prominent advantage over the competition with the MFactory Helical LSD.

Through the smooth and constant distribution of power to the wheels, the MFactory Helical LSD puts the power-to-the-ground and maximises your vehicle's traction. A must for any FWD race car, be it Street, Strip or Track!


- Made from 100% Pure Australian Steel, NOT cheap Chinese Steel
- Precision-machined from High-Tensile Forged Chromoly Steel for increased strength and durability
- Only the highest quality Brighton-Best Hardware is used
- Maintenance-free Gears eliminates the need for special fluids & rebuilds associated with plate-type LSDs
- Lock-free operation ensures no adverse affect to steering response"

My Personal experience with OBX (Something I never told anyone)
1. Had to machine the LSD to fit properly (Both Inside and outside)
2. Changed the Main bolts to proper high tensile ones cause the original ones were crap
3. Drive shafts kept getting stuck to had to machine the inside splines on the LSD

yeah rem you saying that was a prob with ur obx.

Allright! Allright! dude I'm hands down. The reason to why I choose OBX is because it would save me $600 USD (ebay) over Quaife or $250 USD (ebay) over MFactory. Secondly, I do realise and very aware of the problems that customer had with an OBX LSD.

Since I have an access to a work shop, assuming if I did purchase the OBX, I would strip down the LSD, Deburr or break all sharp corners, Check the spring washer (whatever they call it) if they are in the correct pattern, lubricate, change the bolts to High tensile and retorque them.

The high tensile bolts going to be in $$ region so max that I would be spending is about $400 USD for the obx and about another $60 AUD for the bolts. Labour is done by me. It depends how confident you are with the LSD. However, If anybody has a story regarding that the OBX would break down after hard launches or after few thousand kms then it would be very different story and I would purchase an MFactory for $650USD :)
