I have to match the exhaust manifolds with the heads and still need to take the heads back for 3-angle job. It looks like this will never finish :confused:

Yours are thinned in the middle. I wanted to do it also but i am very tired. :) 5 more cylinders to go.

I just spend six hours porting the exhaust side (only for one cylinder). This is the most time consuming job i ever did on my Z. Pure PITA to do. Here is before porting Here is after porting.

In fact removing those exhaust restrictors are PITA job to do and most tuners dont bother doing. I still didnt do mine because i didnt find a grinding stone that can eat those aluminium shit walls.

Looking good. Did you remove the exhaust restrictors? I will keep the stock valves.

The intake walls are not polished. In the 3rd pictures it looks like they are but they are not. Only the chambers are polished a bit.

If you want a high horsepower car you should do some porting job. Here is few pictures showing before and after. This picture shows how the heads looks like before porting. The intake (top) and the exhaust (bottom) are full of carbon. Also the chambers are covered with lots of carbon and this is one reaso that can cause detonation. And the following two pictures shows porting job for the intake (top) only. I did some polishing of the chambers too but its not finished yet. And i still need to port the exhaust walls. In these pictures you can see the valve guides matched with the intake wallls (something that Nissan did not bother doing). The surface its also bit rough because as i was reading it helps the fuel to be delivered easier to the chambers for burning. And finally the top valve openings are bit enlarged

If you missed part 1. Here you go I cant imagine how the engine bay will look like when is finised

3M Products. Hands down.

I understand that because as the guy told me it might look easy but is a very difficult job to do (throttle bodies detailing, chambers, air passages, match it with lower intake. etc.) About the fuel rails we will wait first to see how it fits and then we can move on doing the fuel rails. However i didnt talk with him about the them yet.

Am waitting to see also the result also. If its fits nicely without any problems then i can probably add myself to the list and try to get a deal.

Those are the ones i am talking about. Intake Manifolds

Correction 600 CY pounds each side so 1200 for both.

We cut the front clip of the car and we are using pipe bars. Plenty of space that way. ;) Intake manifolds will cost us 600 CY pounds. (Already agreed) and i know the guy is doing A++ job

The manifolds will be designed like the Escord ones. Move the turbos to the front. Also intake manifold will be ready in 3 weeks and it will be dual one just like the Escord. Some more spec: 65mm throttle bodies 1600cc injectors TH400 3 Speed Automatic Gearbox with 6000 Stall converter with Shifter Methanol Water Injection JUN Rods, Pistons (already in) JUN Stage III cam gears, sprockets, springs, titanium retainers (aldready in) and lots of other bits .....

Tuned it properly. But for street use is not recommended to use so much NOS. Propably 60hp -80hp (turbo Z) and 80hp-120hp(non-turbo Z) is ideal for street daily use.

Guy in the picture is my ugly brother :slap: We are estimating with the 350hp NOS minimum 1400 wheel horse power. Basically the Greddy turbos are indeed old technology but are proven to be reliable and are producing very good results. Ex. When you use it on a Supra it gives you more than 700whp on racing gas.

It is where i leave :D

We are building a Monster 300ZX Fully Drag Car with 350hp of NOS We got the turbos today, our JUN engine is ready and now we are preparing the chassis. The car will be tuned by Mike Kojama (JUN AUTO) coming from Japan And let me tell you that if it works, we are aiming for 6 second passes. NO JOKE Jason Farrow: You remember that chassis when you came to see us right!! Thats the one :)

Thats my 2 year old little daughter :)

I will probably hang around without the hood when its ready. :)

After spending few hours of sanding and polishing. Here is the result. Now i can send them to the chrome shop.

The fact is that there is not much space to fit anything bigger than those. Even with the Type S you have a very tight fit. But i know for sure that you can hold more boost just by changing the springs. We did this on my brothers ones and now they can hold more boost than before.

They are much stronger than the Greddy ones. They are re enforced badly to avoid cracks thats why they might look bit nasty. And nobody can see them when they go in. I will go for the Greddy ones Type S. I ll change the springs to hold more boost

You are right about the costs. However we replicate the Greddy manifolds with 321 stainless steel (cost us around 550 CY pounds) and we are making custom downpipes (around 180 CY pounds). So for us its not that bad.
