Davie Unregistered D	Hi guys, im sure i saw a post a long time about this but cant find it. Was just curious as to how many people have eeked more than 350hp out of std rods and pistons and people's experience's. Sorry if it has been covered before. Davie

I can only comment on my mates 330bhp coupe which had 3 engines in 5 years (though he did hammer it all the time.) I'd seriously advise not going above this figure unless you have very deep pockets.

Davie Unregistered D	Jeez 430hp! no wonder it blew up! Think that is stretching it a bit, what about Watz's 396hp, how long has it lasted and what turbo is he using at how much boos?, gt3071/gt2871? Cheers

Skyline GTST RB25DET DOHC turbo I6 This is 250 standard....put a decat and an AM air filter and you are talking well over 270. If you have ever owned one,you would know that this engine is pure bullet proof.....no matter what you throw at it. The same cannot be said of the 20vt. I love the coupe but we have to be honest here. Last edited by andre333; 12/06/2010 22:23.

Noz Unregistered N	4G63 = One of the greatest engines ever created. Then again, so was the Cosworth YB back in the day. You've got to understand that the R&D lavished on the Nissan RB & SR lumps, as well as the Mitsu 4G63, Toyota 1JZ & Honda VTec y0 engines is light years ahead of the that invested in the 20VT engine. The 20VT engine is in the Fiat Coupe and what else...? The RB lumps were bullet-proof 500+bhp JTCC Godzirras back in the late 80's. Just not comparable in my eyes. I bet the 20VT is good for silly power if you get the right people working on it...

Seems an awful lot to expect from a generic chip, i wonder how much it would kick out if it was fully mapped? Jari's car is 408hp then, what spec is he running, i'm just interested in what sort of turbo and A/R if you know? How many miles has it lasted? Cheers Davie

bridges Unregistered B	Must admit the thought of mega power does not interest me so much. Here is my reasoning well im running 300bhp and in my humble opinion the car is very well balanced, and feels very fast. She has a hybred turbo so spools early with good breathing modifications. The car has lots of usable power, having decent brakes and a full suspension kit, strut brace and new wishbones, drop links, track rod ends. anything other than motorway use I think the extra power would not be hugely noticable and be at the cost of low down pick up. I must admit I would not even consider extra power all efforts now are on improving handling further with camber bolts and lower strut brace as this in my opinion is far more important.

Marko_hr Unregistered M	I thought torque is the limiting factor (and the cause of bent rods)? So a god "linear" live map, without a huge mid-range "bulge", could enable big top-end power? Or the std. pistons melt on high bhp engines, regardless of the torque, due to big temperatures produced burning a lot of fuel, needed for big bhp?
