If you are planning on changing the turbo for more performance i am assuming you will be using an aftermarket ECU,injectors,exhaust manifold,etc if this is the case you may be ahead money wise(the NA cams work fine with the turbo) however if you are going a more budget build route it would be cheaper to start off with the turbo rb25 version....even if you do end up upgrading the turbo (garrett gt30r makes a good street turbo choice with the 0.82a/r turbine housing) btw the NA does run higher comp which when turbod makes a very responsive street motor,however you have to limit the boost and timing to avoid detonation.

Have you thought about importing one, I have a 6Boost steampipe manifold, very good quality and a lot cheaper than 2G..... even after shipping stateside

not that hard cut off the 4wd alloy section, remove the chain drive from the parent box(just cut the loop and pull it out),then plate the hole you have left to pretty it up not sure why though unless you have a cheap 4wd trans already(which you could always sell to fund a RWD RB25 trans) they are heavier and probably have been more abused in a previous life

GT30r with an internal wastegate would be my pick in your situation GT3076 with a 0.82 or 0.63 turbine housing,the larger one if you intend any future mods for HP and the smaller on if you want low boost threshold

if you have increased your boost without increasing your crankcase ventilation you can sometimes get oil blowby your turbo seals

i think the discussion at the beginning of this thread gos through the pros and cons:wink:

Hope this thread isn't contravening the forum rules,if so then anyone interested in the 'leftovers' please just PM me for those that contacted me here are the pics you requested and paypal is fine cam cover fittings -10/-8 example of them on an engine head oil drain -8 ....fitted crank collar

guys after being stiffed by dwayne (badgti) who ordered 3 sets of crank collars,oil drains and cam cover fittings and has been promising to pay ever since.....i am going to have to take a loss on the parts i paid to have made up for him so US$90 for the crank collars US$35 for the head oil drains US$70 for a pair of cam cover breathers i will throw in free shipping if you order a set (4 fittings) sorry to say this will be the last time i offer to source parts i have found useful, to be shipped worldwide, there's always one who spoils it for everyone....thanks badgti from Malaysia

i wouldn't trust a 10 year old fuel pump from any car, lack of fuel pressure can melt a piston in a heartbeat on boost as already mentioned an aftermarket fuel pump would be the way to go personally i recommend the bosch 044 would also recommend the relay/rewire to make sure you have adequate voltage to the pump

Are you talking about an RB30ET or RB30DET? I can tell you from experience that the SOHC version will fit in a 240/260z but is very tight on hood clearance with the factory plenum crossover pipe,so if the mounts you are using drop the motor as low as you could possibly go then it may just fit Of course if you use a front facing plenum a'la rb26,then there is no problem Not sure about freight cost but Castlemaine Rod Shop in australia do the RB30/Z mounts,exchange rate definitely in your favour

thanks for posting the info,glad it all panned out ok

^^^^^^^^yep

i think the bronco had a rear pan sump,and maybe the 4wd F100

contact mike rowe on the forum,he sorted this issue out recently i think
