Stock internals arn't so bad after all 630whp proof
If you have been in dought about how far to push your stock bottom end this may help put your mind at ease.
This is a high milage road race RB30 motor with a stock crank, stock cast pistons and stock prepped rods that has just had a turbo and wastegate upgrade (TO4z and progate 48mm) on the rolling road (not as high reading as hub) it made 630whp and 1525Nm at 23.8psi (1.62 bar boost) 98 pump gas, No NOS.

Thats all well and good mate, but you wont be runninh that kinda boost for a long time or you will deff blow ya engine. Stock internals aren't built to take that kind of boost for any great length of time. It seems you guys build your cars for Dyno Queen purposes or 1/4 mile cars, but dir daily drives and those you want longjevity out of an engine I don't think thi would a safe nor smart option. I mean the supra engine stock can't handle this abuse but an old nissan VL motor which is already as tired or even if you rebuild it with oem items I don't think that the above configuration would be a smart proposition for any length of time. Othwise there wouldn't be such a huge market for aftermarket forged items and the such. I'm sure I could stick 20+ psi through an endige and go for it on a dyno with a big frig off turbo charger on it but I seriously dont think thats a wise decision unless you want to be a dyno queen or a 1/4 mile hero.

Nice,but this is the reason why i dont believe dyno´s.
How much power would it be,put on a german dyno,maybe around 500fhp and maybe 750nm,for sure not 1500nm (No tranny would survive that) Regards Alex PS: Still impressiv for stock internals,give them a blast on german autobahn and they fall to pieces in 1 hours with that boost

Just seen,its torque at the wheels,so its a lot less then the 1500nm,depends on the gear that it was dynoed

You have absolutly no idea what your talking about , I have engines like this that are more than 4 years old, run 10's all day long at the drags, then drive them home, go and have a drift or track day on the weekends and do 40,000-50,000km on the street with oil changes and spark plugs only. I assure you these are NOT dyno queen motors and they are very very reliable. When you are in a position to make educated comments from your own experience with your own engine, in your own car, post on this subject again, untill then, why make a twat of yourself and type out a load of shyte??

This engine was in a race car at a race meet this last weekend, result: Qualify No1 1st 8 lap race (same track as the NZ round of A1gp this year) 1st palce, 1/2 lap ahead of 2nd place. 2nd race, DNF, owner did not top up fuel cell but was 1/4 lap ahead of field 1/2 way through the race when he retired. 3rd race, handicaped, started off back of grid and 10 seconds behind the rest of the field who left together, 3rd place only just behind 1st and 2nd. This engine has raced for 2 seasons before the turbo and wastegate upgrade it has now and was running at aprox 550whp until then. It has never been opened up and has had oil changes and plugs only. I am sure, with real good traction this car would run 9's on the 1/4. Dyno runs done in 1:1 4th gear, 4.1 diff ratio Rob

It depends on how the engine is set up .I have heard of quite a few standard internal Skylines running big power.Unfortuantly there are places in the UK that set up these cars that are not qualified to tune a lawn mower and thats where half the problems are

How many Drag, circut cars use an RB26DETT Motor with an old "AUSTRALIAN" VL Holden Commodore 3L block over in Japan? Where I might add the RB26DETT Motor originated from.
If its such a good engine configuration why is it then in a land of abundant Nissan 3L bottom ends "Australia" that 90% of high performance engine builders do not use this configuration and prefer to go with forged bottom end internals of an already exception engine that has an excellant rev range and an even better one once forged internals have been used to futher that rev range with some cams and different turbos or single top mount like the To4Z and also upgrade the plenum like you do on most of your cars or add a shot of NOS like you also do on your cars bro. I could sell a crap load of nissan 3L blocks with standard internals for less then 300 pounds delivered proberbly to anyone that wants them in the UK  .I mean i know do alot more work like mod the sump etc etc etc (im not here to advertise your services) I maybe not an mechanical engineer but one has to question if its so good why is it only being implemented in such small scale. Unless you can say "prove" since you are proclaiming all these figures, results, motor acolades and have your little NZ buddy bros from sheep land to back you up, you should provided leak down tests and compression tests to justify your "i never had an engine fail" or this engine does this blah blah etc etc . The proof lies with in the FACT. The fact lies within an engine you have built and has been driven to extremes for a great period of time with stock internals and then doing a compression test and leak down test to truley indicate the health of your engines you claim are "bullet proof". Your the specialist performance shop.... you have made claims.... substantiate those claims.... Surely one with so much engine building exp such as yourself and with such a abundant histroy can bolster your own position with evidence to backup your claims... Afterall you are coming from a professional stand point.... PS- sorry for lack of spelling and grammer, C . B .F this time of the morning with pleasentries.
