For stock the turbo would be a GT 25. On the bigger kits with pistons and stroker or just pistons, the kit would include an ecu so that the timing issues would not be a factor. Once we get a kit together we can esentially copy the ecu settings that worked and ship the ecu as plug and play, something along the lines of the Fcon V from HKS, if we can get the software. On the smaller kit for the stock internals, I think that we will not run into many issues with the boost, as we will be running simmilar to Comptech levels of boost, the only thing would be to develop an electrical shunt so that the MAP sensor does not see the positive manifold pressure. I want the turbo to spool that low so that I have something down there, where the car is lacking now. The theory is that If I do a bored and stroked motor the added displacement will help the car off of the line to about 3k, where the turbo takes over and brings the car all the way through red line, with an additional kick at v tech. Needless to say, that with the v tech point lower, and the turbo and the added displacement, you have one hell of a fast car, given the weight. The kit would be available as soon as I can justify the cost of having it built, IE as soon as I can get more people interested. This would not be for my financial benefit, I would not be selling the kit, but my fabricator needs to know the intrest level before starting such an endevor. BTW the bored, stroked, turboed motor will push upwards of 425 to the pavement.

 

Rob, the kit would be bored and stroked to keep the stroke to bore relationship similar, If you want I can just do a bored kit. In either case I would be eliminating the cyl liners in favor of steel. It is to my understanding, that the nicosil liners do not have much benefit, and as BMW has seen, can have many problems. I want an engine that I can feel confident enough with that I could bolt my hood shut. The stock F20 c has not proven that to be true for me * I have a cyl failure, so my opinion is based on this solely* Being that I have had the cyl failure, and Honda will not pay (my car has been modded) I want to go all out, as opposed to going back to stock.

 

Dependant on price, I am interested in a turbo on the stock internals.

If you are working on the ECU, an ECU for NA cars would be nice. Something with different fuel mapping. A chip really smoothed things out on my previous car.

I would also be interested in an upgraded head if the FI route doesn't go or is out of my price range. I know Spoon has theirs, but I would like more options out there.

 

 

Another advantage of the kit that I am working on would be that it would come with cams to take advantage of the turbo, IE less overlap than the stock cams. The ecu would be more than a mere chip, it would be a stand alone ecu that is fully programable. The ecu would not be programable by the end user, but by a qualified tech, as the mis programming could be desasterous. The ecu would be pre programmed for the kit, but since it is re programable, would allow for flexability and optimization of later mods. The big question is now how much would people be willing to pay for each kit, given all of the factors listed in this post? Keep in mind that the turbo and ecu alone is nearly as much as a Comptech kit (about 3500), but the power will be more usable. What components would you like to see (intercooler, fuel system, ecu) and what ones would you like to go without in favor of lower cost? An and all information helps when it comes to developing a kit for a car, but we will attempt to make the kit as flexible for need/want/budget as possible, essentialy offering a couple base kits with add ons available. What does everyone think so far?

 

I think it all sounds great. Personally I am looking for something in the same price range as the Comptech SC. Im not really a fan of the NA route with this engine. I would rather add an SC or turbo. Seeing as I have no experience with aftermarket additions such as those, I trust the advice of the other people on the board. All I know is I want to go faster and kick some ass

 

What sort of power to the pavement are you thinking the stock internals kit could get?

 

so long as the price is reasonable to the amount of power gained i would be extremely interested in this mod

please keep me informed on any updates

 

Everything sounds good, but how are you going to reliably get 425hp to the pavement? The added torque will put much greater stresses on the tranny and diff gears, to the point that I'd be a little worried about unleashing 425hp in even third, as it may strip the gear teeth right off!

 

I think you need to package an improved drive train with this. That was my suggestion to Comptech and it applies more strongly with higher power. I haven't seen anyone commit to what they would consider a price they would pay. It seems to me you need to keep the engine/turbo combo under $8K, but hey, that's just my threshold of pain. I would be hoping to do the whole engine/turbo/drive train upgrade for less than $11K ($12K if it includes a rear end ratio change).

I know it seems like a lot to ask for but CARB certification is just about the only way to sell it in CA. And what sort of warranty would be offered?
