Need some info on 1JZ engines for 180sx build

[Doofer]

[QUOTE=carpo;280017]1. Is there any advantage to splashing out the extra cash for a JZX100 engine over a jzx90 other than single turbo and Variable valve timing??

1.Yes far better engine with the vvti head makes power more easy on bottom,get the right turbo and you will have 0% lag,

2. If i decide to go with the JZX90 engine (twin turbo), Can you make that engine single turbo, if so, what turbo and manifold do i use, what else will i have to do, what cost am i looking at to make it single turbo, and will the standard jzx90 ecu still run it properly minus a turbo or will i need a management system??

2.If you can pick a jzx90 engine up,get it as it comes stock with front sump and if its fresh from japan it may have low km,as if you go getting a soarer engine from uk it could have like 200,000 miles done and only crap oil ever put into it,that even if it was ever looked after...if you want to see nice power with stock cams go with the gt30 or if you like to get 550+ get 35r and fit a set of a/m cams,just get a japspeed manifold as good as any when braced,your stock ecu wont run a single turbo set up,so u will need some sort of management,i have a greddy blue emanage here with a jz harness if any interest

3. In your opinion which engine is the better option for a man on a budget and why..

3.jzx90 front sump engine will make 800+ for a good one,jzx100 engine will make 1200+ with everything,what kind of power you after..!!

4. And finally for now, what actions should definitely be taken when running this engine in a 180sx.. eg, Oil cooler, What size intercooler, rad, fuel pump etc etc..

4.I use a big intercooler,70mm rad,3 x fuel pumps,used to have a oil cooler and took it off,car never runs over 85 deg...after 5 or 6 laps maybe 95 max

Thanks Christy, Much appreciated, All of the above is very helpful.. The engine will be relatively standard apart from intercooler and usual stuff.. i wont be able to afford a better turbo just yet.. The 100 is pullin me in already.. Can you provide every jzx100 part il need to convert the 180, ie full fresh jap engine, all anciliries, two manifolds, standard turbo, R154 with extended shifter, bla bla bla.. Anything il need to have the car running standard.. If so can you put a price on it, Pm me if you want to.. Thanks again

You would be surprised how deep you're pockets will have to go to do a proper job on a oneJ.if you looked at a sr running good horse's you've save you in the long run.what can i say like the simple life ha ha

1j is a riduculose swap if you are on a budget as ytou have said, why spend loads of money to have a stock powered 1j in ur nissan????????

buy a decent running sr20 400-600
s15 turbo 200-250
fuel pump 80
fuel pressure reg 40-50
clutch+ flywheel 300
rb20-25 afm 100
some form of intercooler 150
exhaust 100
nistune and propper map 650

that is going to be a good 300-340 bhp all day long with no fucking around dont forget if you are on a budget mate there is an awful lot of 100euros here and 200 euro there when doing an engine swap like getting a prop shaft made is gong to be 200euros alone

Well said Gem.

If you have a good budget then do the 1 jz conversion. If you have limited funds do a SR.
