mitchy_ Posted May 18, 2007 Share Posted May 18, 2007 i think you might have to take it over the pits dale, as the neo has a higher HP rating. (direct engine swaps are fine, like when i swapped my 'stock' r33 s1 rb25 for a 'stock' r33 s1 rb25. so both were 'apparently' 187kw) however a s1 stagea is 176ish kw, with a s2 stagea being 206kw, so you need to have it inspected, as your brakes, etc might not be adequate for the massive 30kw increase you will gain.

overpowered Posted May 21, 2007 Share Posted May 21, 2007 the pits dont know that, u say the engine no. and its starts with RB25XXXX same as the old one then they dont care, they think its the same (which it is anyway pretty much) pits pick up stuff like suspension bushes and steering bushes worn, etc, and it wont take much to cost u $400 in parts if they pick on it. ive paid rego and insurance on my last 2 cars and they havent been on the road for more than 2500km in 5 years+.

mitchy_ Posted May 21, 2007 Share Posted May 21, 2007 how is your 33 gts-t going anyway? i guess you could just fill out the engine number swap form, and say its rated at 250hp, or whatever it is a stock stagea rb25 is. did your old engine die in the crash dale? save your money on a neo, and buy a nice s1/2 r33 rb25 with some fruit on it.

Stinky Rooster Posted May 22, 2007 Author Share Posted May 22, 2007 skyline front cut isn't an option due to needing all the panels and radiator support. I need a wagon due to the 2 dogs etc so I don't have the option of moving down to a 2 door stagea the only reason I am going to the neo is because the S2 front cut is pretty much the same price as a S1 front cut once its landed (?) and it seems a bit silly to have a Neo and triptronic sitting there doing nothing, especially since the engine and box is going to come out for the welding part anyway. When I drop it back in it is just a case of slotting in the new 'puter and then I will have the spare RB25DET to start building up a RB30DET which is really what the old lard a$$ wagon needs. mmmmm.....torque.....*drools* Link to comment https://www.sau.com.au/forums/topic/168729-wa-licence-regs/page/2/#findComment-3135518 Share on other sites More sharing options...
ssshonky Posted May 23, 2007 Share Posted May 23, 2007 ok .. the pits use a CRAAAAZZZY system for determining horsepower of a motor ( but it works in our benifit !! ) its called the RAC ( no connectiion with RAC insurace as far as I know ! ) Horsepower rating and it does NOT take into effect turbo / superchargers etc. So essentially .. when I changed from an sr20DE to an sr20DET , as far as the RAC horsepower rating calculation goes the DET had NO MORE power than the DE . so that will be a good benifit to dale..

ssshonky Posted May 23, 2007 Share Posted May 23, 2007 [edit] RAC horsepower (taxable horsepower) See Tax "horsepower" This measure was instituted by the Royal Automobile Club in Britain and was used to denote the power of early 20th century British cars. Many cars took their names from this figure (hence the Austin Seven and Riley Nine), while others had names such as "40/50 hp", which indicated the RAC figure followed by the true measured power. Taxable horsepower does not reflect developed horsepower; rather, it is a calculated figure based on the engine's bore size, number of cylinders, and a (now archaic) presumption of engine efficiency. As new engines were designed with ever-increasing efficiency, it was no longer a useful measure, but was kept in use by UK regulations which used the rating for tax purposes. where D is the diameter (or bore) of the cylinder in inches n is the number of cylinders This is equal to the displacement in cubic inches divided by 10π then divided again by the stroke in inches.[3] Since taxable horsepower was computed based on bore and number of cylinders, not based on actual displacement, it gave rise to engines with 'undersquare' dimensions, i.e. relatively narrow bore, but long stroke; this tended to impose an artificially low limit on rotational speed (rpm), hampering the potential power output and efficiency of the engine. The situation persisted for several generations of four- and six-cylinder British engines: for example, Jaguar's 3.8-litre XK engine had six cylinders with a bore of 87 mm (3.43 inches) and a stroke of 106 mm (4.17 inches), where most American automakers had long since moved to oversquare (wide bore, short stroke) V-8s.

bubba Posted May 23, 2007 Share Posted May 23, 2007 I know where you can buy an RB30DETT that's already built dale.. pulled a 10.81 in a commodore Link to comment https://www.sau.com.au/forums/topic/168729-wa-licence-regs/page/2/#findComment-3137701 Share on other sites More sharing options...
