Hi, first of all i will understand if anyone help me and stop reading at this point, as its to much questions... but im starting to rebuild my sr20det, and i want to do a good job, but havent got as much money as i want... so i need you to confirm if my intentions are correct or not.

I already have, cp pistons 8,5:1 compression ratio and 86,5mm bore, eagle rods with arp, main and head arp bolts and studs, have also a engine block, new cylinder head and 0,25 crank, new oil strainer and some more.

Im running 360hp with gt2871, and will boost it to 1,6 for around 400 ,i will go for gt30 for around 500hp, but i think i will run before at least 2 years with the gt2871r if it dont blow up first.

BOTTOM END QUESTIONS

- Im not sure if its ok to have the 0,25 oversized crank bearings, or if its better to find a standard one. Already paid for the crank so its done to 0,25.- Im looking at acl race rod and main bearings, are they ok?- About the compression ratio, will you go for 9 or 8,5? - Wich head gasket? i was thinking in cometic, 1,2mm stock heigh, but maybe you recomend 9:1 compression and then i have to go for a lower gasket.

Off course i will buy new oil and water pump, gaskets and seals

CYLINDER HEAD

- Do i need new spray bars? or its ok with cleaning the old ones?- Do i need strenghtened chain and tensioner or is it ok with complete stock timing kit?- Do i need new rocker arms? if i need them, will you go for stock or better ones?- About the cams, im thinking in Brian Crower 264/264, but also tomei if theyre a lot better, and maybe its best to go for 272/272 and then i wont change them when i jump to the gt30, but probaly 272 is to much for gt2871... i dont know anything about cams...- About the valve seals, will you go for EPP vitton, the ones in the cometic pro street gasket kit, or stock ones?- Gasket kit, cometic pro street or nissan oem?- About the lifters, will you go for solid tomei, replace with oem stock, or just the used ones? i really dont want to o over 8000 rpm.- Valve guides, will you replace if they are new? if you will, wich ones? stock or uprated ones?

- I will finally like to work the cylinder head like this 3 links, but not sure if its a lot of work and if it will worth it:

This, but not really sure about intake and/or exhaust: http://www.junauto.co.jp/proce....html

And also this: http://www.junauto.co.jp/proce....html

I already have brrian crower 1mm oversized exhaust and intake valves, brian crower springs and retainers and greddy rocker arm stoppers.

PERFORMANCE

- About the intake, i will go for greddy manifold and 70mm throttle body. And dont know if my ebay quality intercooler will do the job...

- Fueling, here i dont know what i need... i will go for 740cc injectors, but dont know if walbro and sard regulator i already have will support well.

- Electronics, i dont know if Jim wof technology or apexi power fc tuned by a friend...

- Will you recomend uprated coils like splitfire? or its not a necesary thing?

Dont know if i missed something... I understand that all depends on money... im not rich, so just try to understand that i just can spend max about 500$ per month in the car, and the shipment charges to my country are much more than to usa...

thanks in advance if somene try to read to this point and help me, ive serched, but i only get more questions... as its different set ups and different opinions...

kind regards
