Got the head back last week. It better go as good as it looks.

It's had 13hrs worth of porting done, valve seating, head plained, new heavy duty valve springs and cam followers.

The cams are new 280° to match the intakes.

We just have to setup the cams in the head and it's ready to go on for the test fitting of the itb's.

Hopefully the fabrication of these will be done in the next week or two.

The ports have had a lot of work done on them to change the size and entry angle of the port to the valves, should make a good difference there.

This week I have to sus out an ECU to run the thing.

  • 1 month later...
  • 2 weeks later...

oh man..

oh baby..

that so farkin hot!

Could I ask a rough price for the project?

Could you write up how much better the responce is? how much and where in the rev range the improvements where?

Dunno Rach, just kinda doing it on the side. At the moment I'm waiting for some alloy tube to turn up for the runners, then it's a matter of getting it all tigged up.

Think I'm going to run a Link G3 with a tps and map.

You think thats hot, wait till I've got the trumpets on it, mmmmm. :D

Cost so far... NZ$300 for itb's and NZ$2,900 for the head and cam work (mates rates!)

My mate is doing the CNC machining, so I'll see if I can buy him out with beer. :D

Hey mate,

Nice work. Looking good.

I recently built an RB30DE using 25DE head from an R32 with a modified RB26 6 throttle inlet to fit. Throttle response is unbelievable! I find myself rolling off the power just so I can nail it again. Havent go mine fully tuned yet... Only tuned to 4000rpm. It currently makes 86kW at wheels at 3000rpm (10BTDC and a little rich) so I cant wait to unleash it!

Yours should be somthing along these lines too!! What compression did you end up with?

Again mate, awesome work!!

Cheers for the comments guys. I want to have it going for next season, so that's Novemberish.

Hopefully it sounds good, only 2ltrs though so hopefully I don't have to rev the rse off it to get the benifit out of the itb's.

SR20's sound like rse, I thought the world of rallying could do with the sweet RB sound :P (SR would be better for weight distribution)

Nosmo, what ecu and sensors are you running? I'm not sure of the compression, it's on a bit of paper somewhere. Kelfords were instructed to set the head up for the highest possible compression I can run on 98 octane. MSNZ is outlawing Avgas at the mo.

ECU time...

What are your guys thoughts and experiances with Microtech LT12s ECU's?

A performance shop has recomended this to me and the price seems very fair, as long as it does what I want it to.

I need to read a Toyota TPS, aftermarket MAP sensor and do all the fuel and spark as per stanadard RB20.

Cool. Sounds like the LT12s comes with the MAP sensor going by what the supplier tells me, which will save me a few dollars. He's quoted NZ$1,650. Way cheaper that what I've been looking at previously.

That's why I'm a little bit sceptical.

    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
    • Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
