It's not that I aren't keen, it's more that everyone dreams of the mighty 25/30 rb and it never ends up happening. To do it right costs more than any other RB25 or 30 build. The end user, ie the one paying the bill needs to weigh upi the costs and decide if it's what they want.

As Steve says, you can get low cost RB rods these days, and there are people stocking pistons specifically for this purpose now, so at least that kind of custom expense is eliminated.

masTers, 15k is a safe minimum and more is not unheard of.

IMACUL8, as I mentioned in the other thread, I will talk about it but not now. Too calm at the moment. Will have to wait till I get a bit boozy and can just let it flow.

No more pms please ppl ;) I've been inundated by ppl who want to know about ants l33t engine bulding skillz - well you'll all have to wait! (at least till we confirm what we suspect. don't want to be unfair)

Matt smiths RB30DET is a very basic motor with very small cams etc yet so strong and running 11.6 while having to feather the throttle down the track to try get traction was proof to me how good the 30 combo can be.

This motor gets a real beating and seems to take it with no effort so i now think the RB30DET horror storys are just that.

This motor was built by Wheelspins Steve lee for PER4MANZ running a single ITS turbo.Matts only running modest tune as the gearbox cant cope and the car was build for drifting so who knows its full potential.

Costs of these are much the same as any other RB tho the rods are cheaper than whats avalible for 25/26s and the cam belts easy now and all the normal RB extras like oil pumps etc are the same.In a GTR remember that you have the costs of the sump addaptor but even thats cheap on SAU now.

stock internals 8.3:1 compression

picked up a rb30 short motor $150

R32 RB25DE head $750

Vl Head Gasket + rings + timing belt $250

Bearings where good

Already had a wolf3dv4

used top half of plemum of rb20

If u can do it urself its cheap

How much power is it making and for how long have you been using it?

I've given up on this path - couldn't justify the budget required. Have gone the path of the Neo instead. :)

    • Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.
    • Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.
    • House of Fatz dry dock needs a clean sadly one of the long time stables is leaving this weekend   see ya mr purple
    • Hence why I've only modified my car into a pure daily. Everything has to remain reliable & roadworthy, while providing value and grin factor. It also must not be handcrafted to the extent that the car will be immovable if something breaks because you cannot get or make a replacement to at least limp around with.
    • Nah, I definitely do that kind of stuff with my car. I do drive it around as a daily! It's just that mindset about building a car to actually still use/retain it's function as a car is rare. If you modify your car into a weekender, IMO you've ruined 5/7ths of the fun. It should remain fun to do daily errands in.
