Hy Guy's,

I live in Belgium and recently bought a usdm b18c1 balanced and blue printed
0 miles on motor
AEBS 85mm sleeves
OEM honda bearings (main and rod)
JE 85mm 13.5:1 custom pistons
micro polish crank
hot tanked and super clean
eagle rods

Now I will receive this block this week and want to start building it for the next race year. I now have a B18C6 (European B18C5) with the following mods : Cold air! intake , Edlebrock
ITM , Skunk2 stage II cams , SS full exhaust with SS header. Mugen ECU &
Apexi VAFC , I have 209 Flywheel HP on th eDYNO.

Now on the B18C1 Block I bought I want to build it for endurance racing , so I want it to last for a long time ! I am not looking for TOP performance 9 sec engine , but for a strong running 2.0 liter engine with arround 220 WHP.
Should I put my ITR head on this block with out any modifications ? I have a secund option , I have a stock B16A cylinder head , that I can start modifïng ? Please let me know your recomendations on valves ,rockers, headers , valve springs , retainers, porting (any detailed pics ? ) etc... I will swap mu Skunk cams in this head. I had new Skunk2 valve springs and Ti retainers in my car , but only after 15 hours one of the springs broke in two and messed up the whole engine , so I already had to replace a complete longblock ! Now I replaced the long block and swaped the Skunk2 cams , but put new stock valve sprinfs & stock retainers. I know nobody recomends it , but I was thinking : if Honda sells a new ITR and they are giving a 3 year warranty on this engine , then the stock parts will not brake after a few hours of track racing. Some people over here say I should use Honda B16A valves , because there thicker than the ITR ones .
Over here in Europe , there is little know how to tune the Honda's. Because most trackrace cars can be bought from the factory, Porsches , BMW's , Renault's etc.........

So shoot all the information to me, please

Kind Regards

Other then doing a little port work and valve job on the head sounds read to be bolted up.

However your theory about buying a new ITR motor lasting 3 years. Well yeah of corse when its stock. However I would never run Skunk2 Stage 2 cams with a stock ITR valvetrain. Atleast upgrade the valve springs especailly if this is going to be a high reving constant high rpm track motor. It's just added insurence and common sense.

For example....

<U>ITR Springs</U>
Installed spring pressure of 50lbs
Spring pressure @ 11mm of lift = 140lbs
Spring pressure @ 11.5mm of lift = 150lbs
Spring pressure @ 12mm of lift = 158lbs but you get coil bind

No need to go any further

Other valve springs such as TODA, Skunk2, Portflow etc.... are running around 175-180 lbs @ 11mm, 180-185ish @ 11.5mm and around the 185-195 range for 12.0mm with some such as the Portflow and TODA's ranging @ the 190-210 range @ 12.5mm of lift with still anywhere between 25-40K's left.

The ITR's only had about 20K left @ 11.5mm before bind. I believe the Skunk2 are rated @ 12.3mm lift and 11.8mm of lift on the intake and exhaust cam accordingly.

I'd step the valvetrain up if I were you. Heck if I was building a road car or endurence car I would do it on a stock B-Series just because.

 

What brand is the "SS full exhaust with SS header"? SuperSprint?

 

On the valve springs , sure all this figures look nice , but why do the Skunk2 springs brake after a short time ?
How aboutrh theTi retainers , theye wear out quickly.

I am going to put the Crower Eibach springs and Ti retainers and the Crower valves in the head I am building.

 

ditch the edelbrock IM, it's killing your TQ

So why would you want to use a fully built 13.5:1 race motor? Just use your stock motor and bolt-ons. Take the cash you save to pay for replacement parts and wear items such as pads, tires, rotors, etc.

My .02 cents.

 

Hi,

All that has been done , I've raced this year with a B18C6 engine , I only had 209 HP on the flywheel with the 1.8 setup with stoc pistons. So i want some moer and I could do a VERY good deal on a new build B18C1 85mm AEBS sleved engine complete shortblock ($2.500). and I have that B16A head and want to build a complete new engine and keem py B18C6 as a spare engine.

"I only had 209 HP on the flywheel with the 1.8 setup "
If that SS exhaust system is SuperSprint, then that is why you only made 209 flywheel hp.

 

SS= stainles steel , is a fushitubo japaneese exhaust line .

 

Oh, ok. A lot of aftermarket exhaust systems falls under that "SS" catagory, then.

Where did you get this info?

 

Lots of people make 200 whp with just some jun3's and tuning. pandp head and get it flowing good you should get there no problem
