That is not the update I wanted to read.

Turbo won't work even with sard tuning?

I'd be really excited to see what kind of power you can make with a full built NA motor and a good tune! This is even more appealing to me than turbos, and a lot easier to explain to the insurance company if the need ever arises... I love my F as a DD.

I agree with carbon. NA is more exciting to me..

I agree with both of these guys. I'm even more excited to see what you can extract out of this engine from an NA standpoint than I was to see some frankensteined turbo setup with questionable reliability and tuning options. Good luck and keep us updated!

still interested w/ your build, man. keep us posted!

Yeah, I love NA cars, but this project is awesome!

You just getting it ready for more spray?

MRxSLAYx

Thanks for all the continued support guys.

The motor will be able to handle a ridiculously large shot... If I can find a way to get around the timing. We have developed a way to put a standalone on the car, but it requires a good amount of sacrifices that would force my hand into the big power turbo setup. As of now, the car is going to need a really trick set of headers to handle more nitrous as the Sikky Headers are beyond there limits at 550whp on nitrous. Ill post a pic blow and try to explain why...



Ok. So I couldn't find a good picture so this one will have to do. Looking at the exhaust ports with the head off the car, we noticed that the buildup was progressively worse from the back of the motor to the front. The builder had never seen a set of headers on the motor, but was amazingly able to describe how they looked just based on the buildup that was left on the head. Taking a look at the design of the headers, you'll see that they begin to bend aggressively very shortly off the head. This causes a restriction in flow and increases the pressure on the exhaust side, which is apparently a very bad thing. Because of this discovery, I am most likely going to have a custom set made that will be nitrous friendly.

Good luck, Slay. We're all rooting for you.

good luck with your build

never thought about that bends on the header until you mentioned it

Sikky


PPE


Hard to tell but looks like PPE is a little less agressive with the bend

Novel

Wait, are you still using the 2J platform or turned over to tuning the GR?

LexF

So based on this, PPE > sikky?

MRxSLAYx

No definitely not. PPE has the same problem on cylinders 1-4. Due to the space constraints, it may be best to use larger diameter piping. Ill let everyone know how we move around the problem when we get there.

2JZ in the ISF was a backup plan of a backup plan. The 2UR has been the build of choice from the beginning.

I was thinking they prob had no choice but to have the aggressive bends on a few cylinders with the space available. Also the stock manifolds are terrible with the aggressive turn on all 8 cylinders. Most are basically 90 degree turns. Sikky and PPE are both way better over stock. But I understand for your build needing larger headers. The only thing is how can they be ran without bending so hard? I haven't been fallowing your car stuff much lately. Did you hurt the stock engine?

The Novel headers are equal length correct?
