n42 block v f54

[zzzzed]

I have a few questions regarding the l28 n42 block v f54. I have one of each in my collection.

First off I will tell you what i have planed, I have a p90 head and turbo manifold so i will be adding boost.

I will be aiming for a streetable power figure between 200 and 300rwhp. heres the questions

 

1. which block would be better suited for my application.

2. will i need forged pistons for these power figures

3. how much power can a stock bottom end handle with boost

 

Thanx

For Turbo setup I would got the F54 as this is what Nissan used for the L28ET. However don't go for a large bore ie nothing larger than 88mm ie 2mm over as you want more meat for boosted setups. If however you are going stroker and large bore I would say stick with the N42 as these are better suited for this application IMHO.

That is my 2 cents.

Basically what Mike said.

 

The N42 block is the one to use for the stroker as it can be overbored more successfully due to the thicker casting & full webbing between the cylinder jackets.

 

The F54 is only simeised between 1&2, 3&4, 5&6.

This is better for turbo applications as it provides better cooling of the cylinder bores.

I dont think i will need to boar or stroke for the power figures i am aming for so i will go the f54 and keep the n42 for back up.

I found this thred on hybridz of the in's and outs of l28et it almost makes it sound easy. Its worth a read for all the boost nuts http://forums.hybridz.org/showthread.php?t=84860
