BOBBYr34

Thank you the fab work is not easy. Will be running a full exhaust this car will comply to RTA road rules and comply with emmisions also

Here are some old pics on how the collector was made, it took 100hrs to make Design started from this A wooden template was made first to see if it would work Made from billet 321 stainless

I will make sure i get detailed pic of the merge i hope people can copy this method and use it to there benefit

Below is a pic showing how the wastegate will merge into the dump pipe and act like a venturi to help remove gases from the turbine. Also there will be an addition of a fitting fitted at the bottom of the manifold collector, that can be connected to compressed air on board and spray it in for boost at idle, a good ay to launch of the mark. I know this is all new to alot of people as its all new to me, will have to see how it all works.

People make an offer on the parts

The expansion dump pipe is made see pics below. And the piping in the boot (expensive)

The squish area has not ben touched however the clearance has been changed by closing the gap further then standard. The car will be tuned on E85 caltex.

Ok people i have confirmed the static compression ratio 9.9:1 so i was close

that is correct if you dont understand it i can give you more details

Can you explain what you have said "would significantly change the gas properties" ? When you burn a hydrocarbon what do you get? (stoichiometric )

Hi Nick, This motor build will have both with minimum lag or no lag so response under full boost and response in boost. The boost we are looking at running is 64psi absolute on the turbo side and that should equate out about 34psi gauge before the throttle bodies, remember this is all calculated, we will be follwoing the laws of Joule thomson effects. You must all have a read of the below link now you know why people run big boost rememebr when the F1 where turbo they used to run 5bar boost. http://en.wikipedia.org/wiki/Joule%E2%80%93Thomson_effect

Here is some more info on squish. You can visit this website for more info about motor building. Look under Archive. http://www.theoldone.com/components/ Quench, or squish area is typically the flat area on the top of the piston that's almost level with the top of the block deck. It must have a corresponding flat area on the deck surface of the head to qualify as quench. If you look at a combustion chamber, you will usually see these flat areas, and they will have the volume of the actual combustion chamber between them. When the piston is compressing the mixture, as the piston nears the head, the flat areas on the head and piston come together and force the mixture from those areas to "squish" into the chamber, where the spark plug and burning mixture reside, so you achieve a more complete burn. The quench area also runs cooler than the rest of the chamber / piston. These lower temperatures are where the "quench" comes from. When properly designed, the quench areas can have a tremendous effect on the quality of combustion, and allow higher compression ratios, and due to this they are considered "artificial octane" by scientific types. Bottom line is "properly designed, quench is good".

LOL you know what its not a bad idea, ill make a list of questions from the post that people have asked and i will get hi to answer on a VID so if anyone has more questions please list them. Thank you

I will ask the question again i know what you mean about the area under the curve i remember saying this to John 3 years ago about the VCT. I will post his reply

Well driving a GTR as you might know its very very laggy. Well have you driven a 2.5L sti if you havent well then i think you should feel how responsive it is and i know they have VCT however this RB26 is going to respond like that. The secret lies in the cam selection that allows the correct volume to form enough energy to produce Hp that equates to response. Also the other thing you need to get right with the Rb26 is the Piston to head clearance they call it squish. This also will make the car very responsive. John has said in the past why do you need more then one firing cycle to produce response!!! its should be done in one cycle. What i will do is ill get a copy of some calculations and give you more a technical answer. See attached piston design i know it says 9.5:1 comp but i need to confirm this as it is higher.

Hi Nick, Hey sorry let me correct myself it was the PPG they didint make a 6speed gear set and that why you ha dto change the front and rear diff as its based on R33 ratio's, the hollinger when i got a quote was like the 15K plus. What i will do is ill use the PAR for now and to some tests with ii then ill switch to the hollinger. Thank you for pointing out the mistake i made.

I had my car at Bodyform Peter the master at the finishing touch he said to me, let me do the interior, a person like me that is very picky and want things done perfectly he got it done for me and trust me it was not expensive compared to what i have spent on my other cars. He removed the old oem fabric and if you, sit in the seats they feel better then the Z-tune ,i know i should not say that but its true LOL. If you want it done i could organise it for you. Also the pic's do not justify the look, they look much better in real life. I found another pic Bobby

Hey if you are after a Z-tune i know of another 2 for sale

Matt, You have done a fantastic job in doing this car up , and the car looks hot in white. I used to own a 2002 R34 gtr V-spec II Nur in millenium jade colour some guy in melb bought it. I used to love driving it however it as standard.

You are 100% right John in the past has welded up many ports and remade the design. He was going to redesign the combustion chanber on the rb26 however this would taken even more years to complete the build. Quick Statement NA motor - needs large ports FI motor - needs small ports NA motor- Needs volume FI motor - air speed Have a look at a indy car port size, its very small !!!! John also stated a very important note about the RB26 - Very small stroke small cc very heavy car he did say this motor needed to be atleast a 4L for the weight R34 gtr is about 1680kg

Brad, John loves the exhaust ARC you cant go wrong mate so i will be using it

Hi Tim, Thank you for the advise as i have never heard of modena, i just had a quick look at there website. If the PAR fails ill will make sure i make contact with Modena. You sure can tell me what to do aqs this is why i have posted on the forum as i dont know everything but i do know alot. Or if you have any questions about the build i will make sure i answer it as i am not hiding any secrets about his build.

I had the whole car painted in KYO however the colour is correct but the difference is the way its sprayed on the Z-tune , not sure if you know i Do own a Z-tune and i can see a difference.
