hear we go, the head gasket in my car is less than 6 months old. and it started leaking coolant at rear of the motor by the firewall. so after further inspection i found out it's the damn head gasket. the retard that last replaced it did not put the outer 3 water jacket bolts in. so i put some bolts in it and it just slowed the leak down but it is still leaking. The car does not smoke or have oil in the coolant so I'm guessing that only the outer part of the head gasket is messed up. so im getting ready to replace the head gasket and have a couple of questions.

1.) i have looked and i cant find a good write up on replacing the head gasket. i have never replaced a head gasket on a non American car. anyone seen one? be nice to have a link.

2.) there is good ARP head bolts in it now, can i reuse them or are they trash after being torqued once?

3.) what about a good place to buy a head gasket set? i will probably just stay OEM as the most boost the car will see is around 1.3 bar.

motor came out of a 99 Stagea and is in a r32 GTS-4. any tips, tricks or advice before i start would be appreciated.

find a copy of the RB engine manual, there are a few floating around the interpascals.

A Head Gasket is a head gasket, only pain in the arse part about the RB is getting the cam timing spot on after its all back together.

I doubt its leaking because of those 3 small auxiliary bolts on the side as when I bought mine it had none of them on and there was no leak, more likely its been incorrectly installed or torqued especially if there ARP studs you got to do it right or else they will lose tension.

As for changing it just take it slow and yes it is like any other car just check the head and block to see if it is within range for straightness and also make sure you clean the surface very well not leaving any of the old gasket on. If you dont cut any corners and do everything properly there should be no reason to have a leak again.

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)

      Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.

      A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
