Mine comes out of the garage and runs till i know the door is down then its off down the road. Maybe 3 minutes and i am out of there. The engine is 17 years old now and still going strong. We have a GReddy sandwich plate with thermostat so it gets temp into it quick, but i cant be bothered warming it up. Just drive it sensibly and it will be fine

was going to ay the same thing lol who could be bothered dragging a GTR out of the garage to go get milk lol

Peter at PMC has built quite a few billet engines that are in street cars and he reckons they are fine.

I don't believe too many know Anthony has done it yet but he has and its all going well so far. Time will tell though if it stays together or not. Be good if it does

Anthony at Dahtone has one running a Tomei pump that to now hasn't had any issues and its making over 1000hp though hasn't been pushed just yet

at $23k for a block, crank, rods and pistons i dont know why you would go cast anymore. Sure you need to warm them up but its a no brainer if you ask me

Interesting. I have been looking at upgrading the 6766 with 1.0 rear end on the S14. I was thinking of going a 6870 but kinda looks like i should go back to a 6466....

haha I am no good at drag racing either so I will stick to being bad at just the one form of motorsport

And my intention wasn't to cause an absolute shit fight, I was trying to stir the pot somewhat though. Dyno's are nothing but a tuning tool but sadly there are many out there that would use this thread as a bible and you really shouldn't. There are way to many variables that need to be taken into consideration which most wouldn't even realise. I cant wait till the drag strips open back up. Sadly Sydney Dragway is about to be torn up and isn't likely to be 100% operation until September which is pretty disappointing given it was shut down for last 3 months due to Covid. Shit happens though

The S14 was always making over 400rwkw on the Advan dyno when I worked there. Took it to Unigroup and it struggled to crack 300rwkw.... Clearly if dyno's don't lie then it must be the operator. Its a little hard in this instance to explain the vast differences in performance isn't it? I am referring to mine and Hattori's cars Whats a GTR weigh? google is telling me 1460kgs.... so it has 60 kilos on the S14.... the S14 is a compete street car, doof doof and spare wheel all get left in place when I race it. its 3100 pounds on the weigh bridge at Sydney Dragway. Throw me in it and its closer to 3300 pounds. So lets compare apples with apples.... mates old GTR went 11.0@130mph with a pair of low mounts on Bob Jane All Rounders lol It made 300rwkw.. Standard bottom end and stock box. One would expect 275rwkw to put on a tad more than 18mph.... the S14 went 20mph faster with 50rwkw difference.....

And this is why i hate dynoes and the black top doesnt lie. If your car only manages to run 146mph with 620kw at the hubs i would be asking your tuner whats wrong with it. We have an S14 that makes 500rwkw @33psi with a 6766 and it runs 138mph all day on low boost.... low boost is about 430rwkw. I havent had it back to the track since we put more power in it and made the 500rwkw but would be expecting something like 144mph with the boost turned up. Correct me if i am wrong but power at the hubs would be worth what, 50rwkw gain? so your cars making close to 150rwkw more, comparing it to low boost on our car, but only runs 8mph more.....

what mph does yours run? have you raced it?

what mph does your car run?

Have you raced it? what mph did it run if you have?

What was the 6870 like? I know I could search this post but who the hell knows how far back I may need to go to find a post.... I have a 6766 with a 1.0 rear and I don't know if the lack of driving but its started blowing blue smoke the other day. highly unlikely to be the engine so it might be time to up the turbo a little

yeah well, everyone whinges and bitches that they get busted driving their cars and what can I say.... for the reasons above ET Streets aren't really a 100% legal street tyre

These are the ones I have (link below) and you tell me what the cops are likely to do if they see you using them? Its not exactly a conventional tread pattern is it lol They are DOT approved and we don't have a DOT, its an American thing. Like I said, I believe they have 3mm or so of tread from brand new which is the minimum tread depth that any road going tyre needs to have to be legal https://www.mickeythompsontires.com/drag-tires/et-street-r#sizes

some 300ZX or 32 GTR rims will work fine If you were in Sydney i could have sold you a pair of ET Streets but if my memory serves me correctly they only have about 3mm of tread when new so a couple of runs and they are pretty much done as street tyres.

reliability comes from the engine builder and the parts used to put the engine together mate. I wouldn't say an RB30 is going to be more reliable than an RB25/26. My engine has been in the car for 15 years now. Its made anything between 350rwkw to the now 500rwkw. Its a standard RB26 block with stock crank. About the only mods it has are some GReddy rod and pistons and some head studs. Standard crank bolts are in it even and we used to rev it to 9200rpm. Its nothing special but it was put together properly and that's why it has stayed together.

As Simon said, something doesn't look, nor sound, right. Though I have never used a turbo the size of yours, most PT's love it at the high side of 25psi and just keep making boost. I am at 32psi and no sign of the 6766 stopping yet As an example, my 6766 with a 1.0 rear end at 4500 is making an easy 19psi and 420rwkw. I dare say yours should be making more than 11psi and 110rwkwk

Like I said, a standard exhaust is the only way you will get it passed.

I honestly think you will struggle to get anything but a standard exhaust passed. We got done about 18 months ago. Its an S14 with an RB26 in it. Decent cams, PT6466, makes 500rwkw. Its normally got an old Trust TR race exhaust bolted to it and during the test for the defect the car was 106db at 4000rpm. I don't think the tester realised we had done an engine swap as it should have been 5100rpm. I tried packing the exhaust with exhaust heat wrap. I extended the silencer the TR comes with to about 2 foot long. To the ear I thought the silencer worked really well and figured packing the exhaust would make it even quieter, but not the case. Sadly I had packed the exhaust so much the car struggled to make it to 4000rpm and it was over 100db as it was so failed miserably on the first attempt to clear the defect. Went and got a stock exhaust put on the car and the car was 86db. The test rpm isn't the only issue, they also test the car on deceleration and its normally when you will get a spike which fails the car. When we were tested the mic was placed at about 45 degrees to the outlet at about 50cm from the tail pipe. I think the law states 2/3 of the power band as per the factory quoted figures. They will generally just do what is needed to get the test rpm. I was actually able to operate the throttle when we got tested so built the rpm up slowly so as to not rev it more than was needed. They then ask you to snap the throttle shut. So just jump off the pedal. This is all in NSW though

yeah that sounds more like it. That ran about the same power and mph as the S14 does.

they certainly don't. Actually the R33 does. A car I built went 330rwkw on Unigroups dyno and ran 11.3@125. That 10.6 he said it ran @127 must have been a reasonable back off and in that case his current setup probably should run into the 9's anyway so doesn't really need changing. Probably just needs a decent tune and a nice ECU controlled boost controller so are you saying your car made 525rwkw but only ran 125mph? should be about that yeah. My S14 makes 500rwkw on Unigroups dyno and runs 138mph all day every day.

How much power does the car make now? have you raced it yet and what mph did it run? I personally think you are asking for magical things to happen and they wont. You will find it very hard to swap brands and have it simply bolt up. You will need to change something. Get used to the fact you will need something done to make it all work. As for tune, Mark Jacobsen hasn't been on the scene for a very long time. If you want to talk to someone who knows what they are doing speak to either Anthony @ Maatouks or CRD. If they cant give you reliable info then nobody can. I would also be flying someone in to tune the car than towing it 5000klm round trip just for a tune. At least you know its tuned in your weather conditions and wont be a ticking time bomb once you get it home
