Why not slap a 3.4 in? 

hahaha , I am done , just wanted to see what this work will do.

I know it's also not your preference on how to build these cars and I totally understand why.

Look at it through my eyes, I am 76, I don't want a Fn 35 and can afford to do this work. I really like the R34GTR and it will be my last car in my life, it's the first time I have ever done anything like this and the car is getting better with each modification, well "MY" better :/

 Through the hills I rarely go much under 3000rpm except on tight 35kph corners uphill and 3rd takes care of that and don't carpet it coming out of the corner , it wants to kill you , Mick has no idea what I do in my car , I drive with no one else with me  :)

Honestly , why wouldn't anyone not want to have a skyline that takes off from idle and gets going within another 1500rpm and then is mad up until you want to change gear , it's limited to 8,400rpm.  There was still more to go with the turbo speed with the last tune, I think he stopped at 21,000 rpm and I think the 8374 is recommended to run up to 27,000 rpm and I believe the 8374 gets pushed even faster by some blokes :/ , so I am about 20% ish under the recommended top turbo rpm speed , more to go.

Shit if I want to go to a 1000HP , bolt a 9180/1.45 and off you go , might leave the Getrag on the ground , LOL

So lets see what happens , I know I will LOVE it and stuffed if I know why it upsets some people ??????????????

I don't know about everyone else, but My car spends a crap load of time below the full boost threshold, as I don't think i'd have my licence or car for long if i was driving around at full boost everywhere. While i certainly think that there's an element of chasing the impossible here, the higher compression ratio is going to give a noticeable improvement to every day driving of the car.

In terms of not running E85, every car/engine/tune combo is going to be different however my 9.5:1 stroker motor has no issue with 20PSI on 98 and that's with 260 cams so nothing silly, so its not all doom and gloom. Obviously if you did something like 12:1 you'd have problems on 98 but I think even on E85 you'd be running into chamber design issues there anyway

I cannot imagine driving the car the way it was , well except to sell it :)

I think everyone thinks I want a V8 response , NO! I want the best from what I have and this work is the end of it, love it.

With some early power you also do not attract the wrong attention by not revving higher in town , mine is pretty quiet, but ? 

I doubt he will take it over 10:1 and from what was said I will be OK if I don't go mad

Thats a bit harsh , it's not the same motor anymore , their work has been sorted, LOL

Motors down and seems everything is in good shape to go ahead with the work.

Work sorted!?? Lol That bottom end would have coped lots of abuse for years.

Not years of abuse , they just pulled the motor down and everything is still in good condition and they can do the work ASAP

Save you some reading time and getting to the main problem I had

When the 3.2 stroker was  built the head studs were upgraded to ½”  and the head stud
holes were drilled ~5mm deeper than standard causing a number of them to pass into the coolant jackets around
them.

A total F up and they wouldn't take responsibility for causing it , I had taken it back 3 times and they did nothing but bullshit to me. So I went elsewhere to have it sorted.

Problem found, problem fixed , so easy now ,LOL

21,000 or 121,000 rpm ?

Getrag would not be very happy with that idea ?

  • 4 weeks later...

Both cams going to 272 / 10.5 , could go to 11.0

Going  9.5:1 CR , they are going to use a thicker gasket , in case higher CR is ever wanted

Pistons coming from the US in a week or 2 and the head is out  being ported

Hopefully get it back this year , LOL

    • swaybar swaybar swaybar swaybar swaybar anyway OP, what is currently in your car, are they factory shocks and sway bar? Any sign anything else has been changed under there over the years? And as Murray said....what are effect you looking to change
    • Congratulations on your find  Did you mean it has 6k miles or was that a typo? Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look: 1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands 2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter. Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)
    • Well considering I have the exact same problem with that as the original one I don't think that the ignitor is the problem. I would imagine that this being such an uncommon problem the possibility of getting a new ignitor that is bad in the same way as the old one has to be very slim. I'll definitely pull everything apart this weekend and check the turbo out. Got quite a bit of things to check out Saturday like fuel pressure and the pcv so I'll report back once I do that.  Thanks everyone for all the replies this is all really helpful  
    • Rb's have issues with bottom end starvation, not head starvation. Which either way, you probably wouldn't ever see on a dyno. Strange... What's pump gas for you? Octane rating?
