Gts-t

It's always a good idea in any car to pop your hood once a week and make sure the coolant level in the overflow bottle remains at the same level. If it's not then there will be an issue somewhere, My point regarding the radiator cap is one I've seen quite a few times when a cooling system becomes marginal or is ok most days but gets too hot now and then. A worn water pump impellor (blades) could also cause the system to be marginal some days as could a slipping belt. I haven't seen a worn water pump belt cause such issues but it definitely could if it was slipping at times. as long as the belt is there and is in good condition and is correctly tensioned (too loose could be slipping) it should be working fine, an over tensioned belt is likely to wear the bearing in the water pump out faster but that shouldn't be part of your issue. The cooling system is under pressure because it raises the boiling point of the fluid. This is good for a number or reasons I won't bother going into now, For example under zero pressure water boils are 100 deg Celsius. Under 30kpa of pressure it is about 108 deg boiling point and 90kpa is about 130 degrees. You do not want the water/coolant boiling in any engine regardless of how hot it has been designed to run. Given the radiator cap is nismo and the radiator is nismo they should be fairly new and working fine (ie holding pressure and the radiator not blocked) How old is the water pump? I'd like you to have a look at the water level in the overflow bottle fill it to the max mark when it is cold ( ie first thing in the morning) top up with water or demineralised water if fussy and then check after you drive it every time once it has cooled down for say a week. Particularly if it the temp has gone above 100 in normal driving and then report back. If the level in the overflow bottle is staying the same we can eliminate a few things and go from there. After thinking about this for awhile I'm looking to lean towards a sticking thermostat given how fast you said the temps can rise and then drop back down. As well as sticking it may not be fully opening.

Lots of good ideas but the first thing to check especially given your symptoms is if the radiator cap actually holding pressure. Run your car up to operating temp and squeeze the top hose, you should feel a decent amount of pressure in there. If it's a fairly new radiator cap it's probably not going to be your problem. Never hurts to do a new thermostat, coolant, bleed and pressure test just to eliminate any of those concerns, I doubt it's a blocked radiator given it's a nismo but it could happen. Another issue can be corroded or missing blades on the water pump which I've seen before

Lol my s15 came with those horns I lol'd when I saw them, they aren't very loud I'd say stock is better.

Good build thread mate, I like the attention to detail on the matching parts with the hks and Ross stuff. Looking forward to seeing the motec logger. I probably would have gone with the dash as well, but it would be nice to have the brakes as soon as you can. Where abouts are u finding some of these second hand parts. Good choice on the workshop too they seem to have plenty of experience keeping track gtr's alive. Oh since u don't mind throwing some coin you should chase up a hks fuel rail just so it matches the other Hks gear

Is the foxtel coverage going to be ad free or am I dreaming, I've always been put off by paying for ads

Thanks for the reply noddy, all the best with it. I'll keep an eye on your progress.

Just saw the sneaky gtr badge behind the grill Terry, very subtle I like it.

Welp this is bullshit, since 2007 i always watch fp1/2 and most of the time fp3, sometimes the sky sports f1 show as well. Always watch quali and the race live. I highly doubt I'll get foxtel for this, I'd rather go to bed early and download it the next day, the hardest thing is staying in a media blackout until I watch it. I can't watch a race if I know who wins it its just not the same. Mind you if the championship gets close I can see myself forking out the dough, fuuuuuu foxtel I never thought I'd see the day I'd pay you a cent!

Minimum bump time is 3 days

Call me silly but I actually like the original bumper and wheels. What's the going rate for a new gearbox or rebuild if it does shit itself?

Now they are just teasing you, haha. Just be happy when you get it back it all works and you have no issues with it I rekon. Also I think your number plate would look better back in the stock location. How much longer did they say till its tuned and ready for pickup? Should be a real beast with the 3.2

Sounds good big dog, always had a soft spot for ap brakes I just find something about them very sexual hah. Post up pics of all the gear!

Hey noddy, the issue u were having with the rb25 box failing, was it typically going up the gears ie from 3rd into 4th or going down the gears from 4th to 3rd when it would fail? Thanks

I blew some coin on the trust spec-R hg return flow intercooler kit back in 03. Great piece of gear and the cooler pipe doesn't sit too low in my opinion. Ive got the arc return flow on my s15 and painted it black for stealth. No one ever notices it.

Never seen one of those nismo boost gushes before, nice pickup if it's genuine. If not still pretty tidy.

Nice setup Robbie, I'll be interested to see how you go with the sump

Our dollar just went to shit against the US so probably not the best time for you to sell it here. good luck with the sale anyway mate

Sell it and build a sr20/22/24vet.Or just build up the sr20det. Dont take the advantge of a silvia ie the balance/handling of the car and ruin in by putting a big lump of cast iron 6 cylinder sticking way out beyond the strut towers. If you want that buy an skyline.

So it lines up his intercooler pipe work like the first pic on this page. I don't know but thanks for the clarification on who you were talking about. It's hard to find places that do quality work, on time for a good price. Never hard to find someone who will take ur money though lol.

Any updates yet runkos?

Which fabrication place is giving you troubles?

Looking good mate keep it flowing. Id be sticking with 86mm pistons so you have meat in the block left to go upto a 86.5 and then 87mm piston if the motor is damaged. The benfit will be the block will have been heat cycled many times by then and alot stronger than boring a new n1 block straight up. Really shouldnt have too many issues either way. Also you wont have any maching headaches and expenses if you can find 86mm forged pistons, i havent really looked into it. I think the standard oem pistons arent probably a bad thing with the cooling channel. How much was the seat and rails and who did you order it through, a very nice bit of kit there! The willans harness will go nicely with it Also nice looking tomei baffle, although i prefer the nismo one the tomei will obviously do the job. Who is doing the rest of the work on the sump for you and and what cost. Are you planning to run the drain/vent to the head or just running one vent from the sump straight to a catch can?

Heh yeah i was just stirring a little shit up, i just find it funny how alot of ppl say its not a gtr if its not 4wd when many gtr's have been built and raced over the years in FR format. No disrespect to the 4wd gtr's i was taken for a ride in one recently making 450rwkw and it was an amazing experience for me anyway.

I thought it wasn't a gtr if it's not 4wd though!?

Personally I think cf is so over rated but you have to try different things to see how u actually like them and if they grow on you or not. I think slowmedown has the look of his gunmetal gtr right and from memory it's the factory finish. I actually like both the colour marched look and the factory finish/oem/raw finish. I think the best thing about not painting the lip is if or should I say when you do scratch it it's not obvious as dogs balls and doesn't catch you eye. I'm fitting a gtr bar to my gtst and am going for the colour matched option to start with
