Dirtgarage these sort of comments are pointless and don't help your cause. If winning superlap was as easy as buying a Vipec then they certainly are pretty special. You know as well as anybody that th

Thanks Nick, from what we can barely see, it looks good. hahahah just kidding. From what i know, These are a forged crank. they are not full counterweighted ie 8 counterweights instead of 12. Still a very nice crank though. What pistons did you end up choosing for your kit? cooling channel? Please add better pictures when you get them. I'm sure the rest of the members would love to see it!

I'm liking the looks of that head work, quite nice...

Yeah i know the pics are a bit dodgy at the moment, but hopefully in the next week or so i can get some better pics. I went the lazy route and just got the full kit, so tomei rods and the tomei cooling channel pistons. And your valves/springs etc. look quite similar to the ones i am using as well :)

hmm I like the good head job :)

Roy, can you shed some more light regarding these cams? I am keen to know by what you mean "peaky with a big hole in response".

I cant wait to see this baby on the dyno.

While waiting on the final stages of the head work, There were A LOT of little bits and pieces to buy. Most of the bolts etc were from other rb26's Daz and I had accumulated over the years. I reckon we'd have quite a few rb26's just in parts!

Most vaccum hoses, clamps, pipes etc on the plenum and intakes were over 15years old so I bought all these new from Nissan. Most of these had to come from Japan...... more waiting.....

This pipe was ordered too.

The FAST CD worth its weight in gold.

This oil thingy was not included on a bare block either. Old one was hard to remove.

New studs for intake side for plenum

Also a Nismo Repair Gasket Kit was ordered from Japan. this consists of all the seals and gaskets found in the engine (except half moon seals), a tube of 3 bond, and a 1.2mm metal head gasket. This repair gasket kit is also available in Nissan form however a factory head gasket instead of the Metal one. A great kit!

The Nismo metal head gasket was ditched because i wanted to UP the compression for response. The Nismo repair gasket kit did not offer anything smaller than 1.2mm. Also all the other gaskets that mattered ie exhaust manifold gasket, intake manifold gasket, throttle body gaskets were still made from factory materials. In their place i replaced them with a Tomei gasket combination kit. This kit had all the gaskets mentioned but in metal. The kit also included the Tomei oil gallery orafice as well. Tomei offered gaskets in 1.0 1.2 1.5 1.8 and 2.0! I got the 1.0 for the purpose mentioned.

Head porting is like a black art for me.

When does a light port becomes too much, hurt mid range response and is only good for top end?

that's the problem. you wont know till you bolt it on and try it. the only real way to learn it trial an error. you will almost certainly port a lot of heads that end up worse than they were standard before you start getting them right. which is why it's important to go somewhere that has done lots of RB26 heads as every engine is different.

Yeah, really happy with it. Andre did a really good job. He's been doing it for years now, so i totally trust his work. He has his own flowbench too. The head is also CC'd as well. He charges so very reasonable considering the time spent on it. The head took some time to do as it is not Andre's main line of work anymore. He just does it in his spare time. When i showed JHH they were very happy with it, and said that if they were to charge for something like this it would cost between 4 and 4.5k! I couldnt believe it! I didnt know it could cost sooooo much! I'd never spend that sort of money on a headjob. :P I was stoked! I guess with headwork its like asking "how long is a piece of string?"

Very nice Nick! Cooling channel pistons! I have always wondered how they actually make these. They are a forged piston so how do they make the channel? Nick, when you're ready to do the hoses and clamps, let me know. I can get some pretty good prices on the Nissan stuff. I've spent enough with them!

i have heard that this is great for drag cars, but may not be good for street. is this true? what benefits and gains can be expected? how does this affect response?

      Starting again

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.

      By Duncan · Posted

      Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
