Looking good there. I wonder if its conceivable that maybe a few guys around the world came up with the same result and didn't tell every one. Its not a new engine and Im sure more than one porter has cut one of these heads into sections to see whats inside

Impressive power. well done

Yeah its me building his engine. It may be a year away Im building a few other engines at the moment so they are keeping me busy

It will be interesting to see it. I will hopefully have caseys finished as well. you can have a race

Im sure you will be able to drive it on the street. Im not sure that with 50mm carbs and a lightweight flywheel with that cam it will be that great for cruising. But each to there own. If that's what the customer wants then that's what they get

300hp at the wheels is about the limit of these gearboxes. Some people will get higher but thats the generally accepted limit

Yeah your right. I dont realise this was a race engine I thought it was a road engine. Hard to drive an engine like that on the road. It will certainly not be scared to rev with that flywheel , cam and carbs.

600 thou is alot of lift to get that 360 hp potential. Its going to be hard getting the guides to last. 15.24mm lift is huge. What cam are you using

Beautiful car. I would love to see this in the flesh.

Its a hard job building engines for a living I tried it as well. Good luck in the future in what ever you do. If you have your advanced trade look into retraining as a teacher and teach shop. Its a great job

Yeah your right, the rd28 sump is deeper it bolts on I used one when I was doing my conversion. You just have to cut the bottom off and weld a plate on. Not hard at all

I love the rocker covers. I would love a set of them

The rb30 is king for sure, i am using one in my skyline. rb26/30 I was just concerned about the block height and that's why I didn't suggest it

but the rb25det puts out 250 at the engine with alot more torque. We have an rb25det std in an r33 drift car. it had aftermarket steaam pipe ebay exhaust manifold kando dynmaics turbo. front mount intercooler high flowed injectors, its making 437 hp at the wheels Hardly an expensive engine to build as anything that you bolt on to an rb20 will bolt onto an rb25 the only difference in price is the purchase of the engine in this case its more expensive to buy the rb20det and you dont get the big gearbox like you do with the rb25 engine Going on the calculator and giving the car 1100kg that works out roughly to be a flat 11 second 1/4 mile. I say roughly as there are man more factors than this. using the 287 hp gives using the same weight a 12.8 second quarter for the same money. I know which car I would rather be in http://www.asianautospares.com.au/index.cfm?Do=View.Product&ProductID=43 http://www.jdmenginedepot.com/jdm_engine_details/50/Nissan_RB25DET_Skyline_Swap

The 25 bolts in place of a rb20 the rb20 has small ports that dont really flow that well in comparison. Its not just capacity you are picking up here but also alot more flow. i guess its like putting in a l24 or an l28 what would you fit.
