[Guest j_string]

Hi guys I used to have a s13 240sx with a sr20det now sold everything to come back to the source, now searching for a 71 72 good Z to be my next projet car I wanna get something around 400rwhp withch I can have witht he sr since i am used to it but I have no preference about the swap I want to stick with nissan thought ( personal prefenrences ) So I thought about the rb try searching for about 2 3 week by now didn't found any good info on the rb witch one fit in whats the problem cost in general.

 

My other question is what are the possibilities with the l28t from the 280z could'nt find exact specs high hp on stock internals what kind of turbo peoples usualy use what kind of cams how mutch the old technologies ( not cross flow and sohc ) will get in my way to have a good reliable street engine.......

 

 

Thx for your time and your help

the l28et is a very strong engine will handle alot of punishment even in stock form.I am making around 320rwhp est from the hp calculator so i'm sure it's more that that.I am running a t3/t4e hybrid turbo(very streetable) and a custom dp.Also running a 65mm tb,420cc injs and the STOCK EFI.I am getting a haltech this year but all my times i ran at the track i ran on street tires and pump gas with the stock efi and ign system.I hae broken three pistons but it was from my stupidity not from the engine problems.I let it detonate to much breaking the ring lands on the first and second piston a few times.My best quarter time to date is a 12.38@114mph pn a full tank of gas and some 205-55-16 crappy street tires.I do run a heavier clutch and aluminum flywheel and love them both.Even tho the non cros flow head does restrict the performance you still can get really good hp numbers with the l28.Just ask timz he is making well over 400rwhp and even more rwtq i tell you one insane machine.
