goddam that plenum is a master piece !!

how much power are you aiming to run?

The aim of the build was 1000HP so trying to crack that or to get as close to it as possible. Realistically though if everything goes well i should make well over 600awkw.

Hi Sedat, i dont know if Barry metioned to you, i was over there a few Saturdyas ago to compare our head to a few of his race heads and we laid yours out on the table as it was the best ported there to look at and compared to mine.

I spent 8 to 10 hours the weekend before working on 1 exhaust port (i use to port a lot of heads between the late 70's to early 80's before Stefan was born and i had to put the die grider away and actually work for a living), taking my time, studying the casting and port shape getting it to 95% of where i wanted it, i had not done the other 5 so it was time for me to sit down and look at some others professionally done and take some detailed measurements, study them and to see if my theory/direction was wrong or right.

End conclusion is our exhaust ports are virtually identical, most areas are indentical to the exact 0.01mm in size, i have a few areas that are no more than 0.5mm larger (nothing), my flange outlet is around 1mm larger (you have a reversion step from the head to mainifold join which is good, my gas reversion step im building into the 6boost manifold which explains the 1mm port outlet diffrence) , i took a different approch (slightly) on the short side radius near the valve, i pushed our exhaust divider wall back 2mm more as i felt there was a restriction there which is a minor diffrence, i could be wrong that it was a restriction, my ideas VS a professional porters.

All i can say is your head was very, very well done.

Looking at what it cost to get yours done and the time im putting into ours, im questioning if its just wiser to hand it to Brendan to get done and just sit back and enjoy life. ;)

Our combustion chamber shape will be different to yours (spoke to Brendan about it last time i was there and he said its something that could work out surprising for E85 but its untested on a RB), looks like i will be the guinea pig with the idea.

They did a great job on that head, you will do well with it....should push out some great numbers....

Whats this i heard from Barry that you and a mate almost knocked out the 6 foot something window guy a few doors down after he mouthed off? I heard he ran off inside to hide like a little bitch when you 2 went over. :D

Good because a few weeks earlier i also had a run in with him.

Edit, forgot to mention, you will need to wipe down that inlet mainifold, i was drooling all over it, its a work of art, take lots of pics of the inside, once its on you wont get to see the craftmanship inside again.

    • sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving. 
    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
