I mit take you up on that offer I will let you know by wednesday I was going to buy a starter box off a nice guy I got parts from on ebay but then this happened so I need the block more.

The plus your talking about is it Blue or Gold I saw a new one with a Gold head on it. And yes next time I will check the Block when I blow plugs

The orangish goldish head is either the old Collari edition 35+21, the Cordoba or the new Collari 35+21. All are good motors but only the new Collari with the long crank or the standard blue or purple head 35+21 use the standard R7 rod. The other 2 have a smaller crank pin.

Roniel I have the $180.00 but the GRP company burned down, So how will I get parts for the engine you have to sell. That is my only problem out here in NY I do not have a place that I can get the parts for that engine.

All you really need is just a stock standard 35+21 unless you are running big races on big tracks and plan to make the A main. And if you run on short, slick tracks you don't even need that much. Go with a cheaper Nova WSC.

The new 35-plus-21 has a purple head and is still using a 5mm crankpin. The Collari versions (except the latest Lostallo edition) run a smaller crankpin which will give some issues.

Got mind problem here : simplicity vs. geeky desire
My mrx4r and os vz-r engine can surpass 5 minutes refueling time + 1 extra lap. I have no problem with run time.
Here is the problem : should I use the exhaust cooler ? ..... I try to keep my car simple, but sometimes my geeky desire is really overwhelming .....
Is exhaust cooler really increase run time ? Is it really necessary ?

No don't get it wrong I can handle the car very well What I don't understand is the HITECH italy engines. There powerful engines and to pick one I am not sure where to start and to tune one of these things is not easy for me. But the handling part I got.

I found a site that sells the piston/sleeve,con rod and bottonhead but they want $203.00 and that's not shipping and tax on that. What you think?
