can i turbo the N42 block even though its not a turbo block? also rods and cranks are same as turbo blocks?

Could someone tell me if they have the 280ZX snowflakes wheels installed on a 240Z? If so, what maximum size tires can/would fit? Because I want to use the 225/50/15..

As for blocks to use with an overbore: the N42 block has better thickness in the cylinder walls and is a FULL siamesed block. Also, I have never heard any reports of the lack of coolant passages between cylinders being a problem in terms of cooling. The best years of N42 being the ones made for the USA market in 75-76. From what I understand they had higher nickel content in the block. However, any of the N42's are good as they are all very strong blocks. As for the F54, the cylinder walls are thinner for better cooling and coolant passages between the cylinders (hence the non-siamessed). You you can overbore the F54, but the F54 is really not the first choice as it is a non-siamesed block. I have even seen a rebuild book that states it is siamesed, but it has large passages between the cylinders, and hence is not really siamesed, and not all of the cylinders in the F54 even have any joining material between them. I would use an F54 on a turbo engine with stock bore or for high compression on a stock bore. So, do not believe anyone who tells you the F54 is the choice block for a overbore or that the F54 is superior to the N42! They are just repeating what others have been told. People who have been to Japan will tell you that the engine builders in Japan have been using the N42 since the start, as they knew the properties of the N42 are way superior. Leave it to the Japanese to be way ahead! Also, get the block sonic tested and balance all components!!! Do not skip this for a power build. For a stock build with stock bore, you can just rebuild like normal. Also just to comment on my understanding of the L28ET limits (stock internals, but sitll I would get ungraded rod bolts! The rod bolts being the weakest link in the L-series engines). From my understanding, the stock L28ET can do 350 BHP at the upper limit with no internal modifications (external only like stand-alone, injectors, ignition, etc.)

Does Z theraphy SU carbs comes with SM needles?

Does anyone use NGK Iridium plugs work with MSD 6AL/ZX dizzy? Please let me know how it runs..Currently i have ngk iridium but i want o make sure it can run with MSD 6al with ZX dizzy..

Do you guys know a place on SoCAL Inland Empire that repair dented/re-chrome rear 240Z bumper..Thanks..

I currently have a JDM L28 motor with F54\P90 head flat piston ...running a su carbs for now..How close i am to have a L28ET..I already have a '75 N42 intake and exhaust manifold..Please help me list down the parts..TIA

Any ideas? I know its not common..

damn sound like rebuild..

Im having a noise from tranny like a metal to metal whining noise..when on idle it make noise but if i step on the clutch its gone I just recently change my clutch to Centerforce II..You think my new throwout bearing gone bad, input shaft bearing or clutch mis-adjusted? but other than that they all shifts fine on all gears with no noise..pls help..

I saw a listing on craiglist a N33 intake manifold for sale with remove emission..is this ideal for SU carbs and same performance as N36 intake?? Please let me know your opinion before i get them..

sure...where are you located???

Fair enough

Please help someone selling a turbo block with flat piston rebuilt for $350..but the number 5 cylinder have a sleeve on it..what do u think having sleeve on a one cylinder for longevity, wearness and vulneverity..

thank you Arne..have done full polyurethane bushing and how was it?
