Which Pistons give a 2.0 lt displacement and what camshafts did u used for 8600 rpm? Is the block from a BP Z3 or BP4W ENGINE block and which cylinder head? I see that there is no crank sensor?
Thanks

Hi iliasfyntanidis,

of course there is a crank sensor. The engine is a BP4W engine, because there is no VVT. The pistons are 85,5mm JE pistons custom built for us.

I see the pictures are not working at the moment. Directupload has some problems at the moment. I hope they fix it soon.

These are the camshafts in this engine:

Sorry @Guido@SPS  I meant cam sensor.
I see from the camshaft specs that they don't have enough overlap,as we all know its necessary and essential for N/A applications.
Even CatCams gives them for turbo applications and they have Lobe Seperation Angle of 110 degrees which doesn't match the engine characteristics(N/A) and the lift at TDC is tiny.
Do you mind sharing the timing of these cams for your application?

Mine camshafts also from CatCams which are for N/A application follow the usual norm,tight LSA and more overlap,that's the reason i am asking?

Any reason why did you selected Supertech(single or dual?) springs over the PAC springs CatCams recommends?

I'm sorry, it was the wrong datasheet. The datasheet was for another car of the customer, which will be turbocharged.

This is the right sheet:

Thanks Guido!It makes sense now.Are you using the OEM oil pump and harmonic balancer with this engine?

Ilias, they probably use grouped injection and wasted spark.

Guido, what do you use for engine management? Why didn't you go sequential?

Engine-wise, do you have any pics of the engine block with pistons installed without head? I would like to see the distance between 2 cylinders on the block as 2.5 overbore seems a lot.. Interesting!

Also please upload smaller pics as the thread takes forever to load..

Thank you

Hey Nitroking,

the ECU is a MSLabs MS2. We saw no advance in going sequential so we didn't change it.

Here You have a picture of the block:

This is one of the toughest conversions we ever made. A 2.5L V6 KL swap with an ITB. We had many issues with the car until it was ready to go on the street. But at the end we solved every problem and now the car runs fine. The block is bored from 2.5L to 2.6L equipped with Wiseco pistons and K1 conrods, main and conrod bearings are Toga high performance bearings. The head got solid cam followers with different camshaft and an individual throttle body. The engine produces 250hp with an airbox on the ITB and 300hp without the airbox.

Specs:
- 2.6L KL
- Wiseco pistons
- K1 conrods
- Toga high performance main and conrod bearings
- Catcams camshafts
- solid cam followers
- custom ITB
- custom airbox
- mishimoto radiator
- BC Racing BR-series coilover
- DIY microsquirt ECU
- Rota RKR 8x15" 10mm offset rims

This 10th-anniversary NB got in our workshop because on our last trackday in Anneau Du Rhin the timing belt got destroyed by some dirt of the track.

We supposed the valves also got broken because of other camshafts and higher compression, but luckily nothing else got broken.

It is a 1.8L bored to 2.0L with an ITB and very aggressive camshafts. On the dyno it produces 230 natural aspirated horsepower at 7800rpm.
Because of that power and a shorter final drive in combination with a 6-speed gearbox and a shortshifter it is really much fun to drive. :D

Specs:
- 1.8L BP bored to 2.0L with 85.5mm pistons
- Jenvey ITB
- Mishimoto X-Line radiator for Honda Civic
- Reverie RH carbon airbox with custom ram-air hose
- König K 5000 seats
- OZ Ultraleggera 15 inch

This is a really nice sleeper setup. A 1.8L NA with a GT3071R turbocharger producing more than 350hp.
The owner doesn't want a rollover bar because he wants to keep the sleeper look.

Specs:
- 1.8L BP bored for 84.5mm Wiseco pistons
- K1 conrods
- ACL main- and rod bearings
- Boundary stage 2 oilpump
- ARP head stud kit
- Garret GT3071R turbocharger
- ATI Superdamper
- SPS oil cooling kit
- Mishimoto radiator
- Skid Nation reroute kit
- 6-speed gearbox
- MiataRoadster short shifter
- StopTech BBK 280mm
- Rota Strike 8x15 20mm offset with Nankang AR-1
- CanChecked Display universal 2.8"
