Hey,

A mate of a mate of mine offered me a cheap port and pollish for my R34 GTT yesterday and was wondering if i should go ahead with it or not.

I have some understanding of what is involved but i just wanted to get more info before i do anything about it.

What are the pros and cons of doing it and has anyone else done it to there GTT?

Is there a noticeable power gain and saving on economy?

He said he will do it for $50 / cylinder = $300 plus the cost of getting the head re-done and it will take about 2 days... is that a decent price?

Would people recommend it, and if not, why?

Any comments are greatly appreciated!

Thanks.

What do you mean the "head re-done" and how much for that? Last time I checked that part of it would cost $500-600 making the total $900ish which is still cheapish but do you need it? We need more info on your setup to answer that question.

yeh its worth it...if your engine is already pulled out and apart and your doing other mods to it. But just for the sake of pulling your std motor apart and getting the head port n polished and then faced with a maybe on the valves if thats what hes referring to for the 'head redone' then its prob not worth the hassle for the money even if it is cheap.

Hey,

Thanks for the replies guys!

Yeah, i am using the stock turbo right now with no plans to upgrade it till it dies...

I still have stock ECU, injectors, fuel pump etc...

My current performance mods are:

- Air pod

- Exhaust

- 600mm FMIC using stock piping

I think he meant getting the head machined or something, and he mentioned something about the lifters too...

The car only has 56,000kms and hasnt been flogged from what i can tell, so the engine still should be in very decent condition... He recommends getting it done as it is a decent price and gives you more power etc... but if its gonna cost another $500 - $600 for the head, i think i'll leave it.

Next time i see him ill ask what exactly needs to be done to it, coz he said he has to get that done by someone else as he doesnt have the equipment to do it... i thought he said its around $150 though? I'll have to double check.

Thanks all.

I'm probably way off the mark here.. but isn't the idea of machining your head to increase compression? Don't you want to decrease it?

Tell me if i'm wrong guys.

Depends which part of the head you machine.

Another couple of costs you seem to have forgotten about are a new head gasket and labour.

Also with stock everything there is absolutely no point whatsoever in doing this mod.

DON'T DO IT.

I say otherwise; DO IT :P

Change the head gasket; change the valve springs; camshafts; valves... replace head studs; do the port and polish and end up with a race-prepped head!

Sure you might live in a cardboard box after; but you know it ain't stock no more!!!

Ignore this person. He is an ass.

waste of time for your set-up. $1000 could be spend elsewhere for much better gains.

Agreed

Far better bang for buck mods witrh your setup.

I could think of around 8 grand you can spend elsewhere before even coming close to needing porting

    • The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.
    • No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️
    • Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney
    • I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"
