hey

here's the deal, UH was supposed to get me a redtop but its been 4 months and now they said they can MOST LIKELY get an RB20/25 faster. so here is my situation...This all for my 95 240SX(S14)- probably weighs 2700-2800lbs...I have a FMIC, intake, BOV, fan kit, clutch, flywheel, boost controller, turbo timer, exhaust, downpipe, and gauges, and i was planning on adding a T3/T4 turbo (or something that is able to have the most streetable power with a 350-375 range on the street and 400-500HP range for the track and weekend fun) and a few extra goodies for the new turbo(ECU retune, injectors, manifold, ETC)...I WANT TO RUN 10-15 PSI on the STREET and around 20+ PSI at the Track..i probably wont be in any competitions, this is just a hobby and to have fun before i die. my questions is..if i put all this on a SR20 how much HP/TQ, 1/4 time for street and track settings would i get(estimate)? for the RB20 Hp/Tq 1/4 time? for the RB25 HP/TQ 1/4 mile time?

i was thinking that the SR20 or the RB25 would be the best way to go...i just want to have all of the bolt on's and an upgraded turbo package w/o spengin an extra 5 grand doing the internals, but i also want it to be reliable at the same time. What engine has the strongest internals?...FOR EACH ENGINE, what HP do the stock internals hold?? i dont wanna spend the extra money on the RB25 if i can get to my HP and 1/4 mile ET goal w/ an SR w/ the turbo upgrade...what do you think would be easier, more reliable, more fun to drive, and easier to find replacement parts in case something broke...

also i have researched thourgh many nissan boards and everyone says the I6 has more linear power and doesnt feel as peaky as the I4(SR0)...what exactly does the mean? how does the driving feel different?? i have never driven a turbocharged car before.
ANYONE please post your opinions/flames/ideas or whatever about the decision b/c i have to decide in a few days and i need to know all the good and bad about each engine...oh, and BTW, dennis at unstable hybrids has gotten in touch with me and he is a very nice guy and his helping me out greatly now with getting me an engine ASAP...thanx
Jon
