Is It Worth It?

[LUME]

well soon i will be having a few months stint with footpower, and so the skyline is getting a bit of a make over i have interior organised panel and paint and suspension and wheels, been reading up tonight and i have been in formed not to turbo mine (dont ask) as i will lose my lisence and car as soon as its all done and i get back on the road, so was jsut wondering would it be worth building a high comp rb30 motor with the 25 head mated to it, acl pistons and rods bored decked head cams hypertune manifold and so on, is it really worth the hassle and is there gains to be had if built right?

car is staying the same colour putting work meshies on it stripping out reear seat bolt in cage seems rediculous yes indeed but horses for courses, and what can be done about my diff gears? they are way too tall for an n/a motor, think that the 200kw mark can be made achievable, i know this question is asked alot and my apologies for this but anyones input would be good?

cheers luke.

Well 200rwkw is achievable yes, but at a price.

Personally i would find the nearest bridge and throw that head off it has hard as I could. There are more gains to be had with a 26 head for only a few $100 more.

If that 25 head hasn't got VCT then you should be ok but you'll never be able to run as big a cam in the 25 head then what you can in the 26 head without changing the head to a solid valve train (Which is what the 26 head comes from factory) and that is where basically the majority of the power will come from.

I could have bought a V-Spec 32 GTR for the money that I've spent on my motor so far, If you are mechanically minded it'll be quite cost effective and how far you go with the build (i.e. complete rebuild or just slap some parts together and hope for the best.)

yeah it does seem like alot of hassle jsut to have something thts not as common doesnt it, building it and doing all the work is no problem apart from machining of the block, jsut dont want to pour a whole lot of cash into it and regret it later which i most probably will...although it will be a whole different car, really i know this will sound stupid but something tht will atleast spin in second not first and then die, and thts not going easy on it thts sitting it off limiter and dumping it. i know that i could buy something like a commodore and make more power but a commodore jsut does not offer the same handling as a skyline does, and the only other car i will buy next if i dont do this will be crossing back to my roots a rotary

I'd also go high comp 30 bottom end/26 head but i'd put on 6 throttle bodies from 20v corolla motor w/custom intake manifold etc etc.
