Well its a carbon copy of Elrodeo666's head which was good enough for 445 kw at 1.4 bar on -5's.

Have a look at the inlet ports on Brad's engine (SHOWOFFR32)... that is what they should look like.

BRB. I'll go tell the bloke that ported the HKS drag car that he did it wrong.

Go ahead... All I am suggesting is that the port looks polished from the photo.

To enhance mixture quality it is better to have a textured inlet port surface, especially considering you have massive injectors that wont atomise very well.

Well they proberbly are. But considering the guy has built mild to wild RB's day in and day out for the last 20 years, there must be a reason why he has done what he has done. Who know's what that reason is. I'll ask him in two weeks time when Marcus will sit him down and call me from Japan.

The guy in Japan who has done all the port/polish and r&d on the head has built more high powered full race engines, 9 sec drag engines and drift spec engines then most porn stars have ever had roots.

And yes its polished as well. Why..you'll need to ask him about it but as one of Japans top engine builders who has built 100's of high spec engines, I think he has a resonable idea of what he's doing.

But hey everyone has their opinions.

And Paul its 445kw @ 1.3bar

Just to be clear, your talking flow from a polished port vs fuel atomisation from a rough cut port right?

I figure the rate that Paul's car drinks E85 it probably won't make a lot of difference when its on song. Its not as though there are a lot of injector options to provide a streetable 2lt/min injector flow. The value of optimising fuel atomisation from porting/polishing methods could probably be weighed against the options available for injector spray patterns for similar effect.

Theres more going on with this head than just a port /polish job.

Been all machined up at Naprec to HKS race specs and then some custom work by HKS.

It has been designed purely for response and slamming his arse hard back in the seat and fro getting around a track nice and quick.

Pauls head has a bit more done to it than mine and has been built to handle 600~650kw if he ever chooses to go down that path.

Anyway this is Pauls build so wait a few weeks and he'll let you see whats what and at the end of the day it all comes down to what it does when it's all bolted together and tuned properly.

It will be interesting to see how it all ends up..

Hopefully one day maybe a V-cam and those new turb's that Gav has, it would be quite an animal.

Unfortunate about the old engine!

But it will certainly be interesting to see how this new setup performs in relation to the old setup. Especially with the addition of the new head. What sort of port job was done to the old head?

My mates car runs low 9's with a near std head, ports are just cleaned up. Makes about 880rwhp. What bigmikespec has said holds true, port finish 101 regardless of head type or setup usually doesn't go any finer finish then 80grit. Polishing the surface slows air speed and ruins mixture motion through the port. But maybe this particular guy has a formula that works for him and it goes against the theory that everybody else in the world works around. It will be interesting to see if it makes a difference or not.

Gotta keep an open mind about everything!

    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
    • Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.
    • I also got the same floor mats for a bit of extra bazzaz haha
    • Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
