im intending on leaving the car manual as it is going to be a daily driver as i enjoying driving manual more and a quick shift auto with stall converter is not my cup of tea. my aim is for a 11 second street driven car. I don't do any track/drift work so handling isn't that much to me but from what i heard a 6 cylinder isn't that bad handling in a s13 as there are plently of people running rb20's and if they handled that bad the conversion would rarely be done. But i have seen plently of rb's going around town in s13's. Also if its of interest the 1jz is actually 2 inches shorter than the rb20 motor. I don't think it is going to be as much of a beast as what you guys think 270rwkw the acceleration wont be as violent in a 6cylinder as what it would be in a rebuilt 4 cylinder with that kinda power as i would need a big turbo. What kinda turbo is needed to make 270rwkw at like 17psi on a 2.5 ltr 6 cylinder motor? thanks for the help cheers snuffles

thanks for the input guys i would still like to hear from other peoples experiences with both motors and what kinda power this engines can punch out internally standard and what kinda power they can make with what mods and turbo. thanks for that tuna so you guys are pretty close mod for mod? i wasn't going to do the exhasut either too expensive and especially cause im going with a single it will be a waste of time.

well to buy a sr20det half cut you are looking at $3500 then you look at the price of building it... atleast $8,000 decent rebuilding including head gasket stroker kit bearings and machining and so on (including labour), and that doesn't include labour on fitting the motor give it will only be like $500 or so labour and then allow for parts and materials. you are still stuck with a bog stock motor that is just rebuilt.... and i still get back to the fact that rebuilt motors can blow, whether just from too much power and thrashing it to much, or whether it is from bad luck with something going wrong like leaning out in one of the cylinders and poping the motor (i know it is highly unlikly but it can happen) then i gotta pull the motor out and rebuild it yet again then there goes thousands of more dollars... can you guys see where im comming from, where as with the rb25 and 1jz they are pretty strong internally stnadard and if they blow after a year or 2 i can just replace with another stock motor which would set me back $1,000 for the motor istead of another rebuild. also if you setup your suspension correctly you can get the car handling pretty close to the way it handles with the four cylinder. can you see my side of it or do you still think sr20 is the go?

i feel that a four cylinder is going to be too laggy and not as streetable as a 6 cylinder would be. i just recently sold the ca as a package with motor gearbox loom so on and so forth. so by the time i bought an sr20 and built it seems rather pointless if you ask me considering the cost of building a stroked sr20. also what happens god forbid soemthign happens with and oil pump or the car leans out (or in my case some how my sump plug falls which actually happened to me but in my case i found out beffore i ran out of oil)o and i pop the motor i will have to pay for a new rebuild where as you can buy a 1jz half cut for 2200 (automatic) that includes everything so i think that the sr20, altough a good motor isn't the way i want to go i am looking at making a 300rwkw daily driver. i think a 4 cylidner at that kinda power would be a bit of a pig on the road with lag and so on. this is just my opionon and im wanting to discuss it so i make the right decsion thanks for the advice. cheers

well the thing is my friend has already done the conversion and he left the stock dumps as they are expensive to change, but he went through the same mechanic as im going to go through and he said he only charged my mate an extra $600 to do the conversion compared to an rb25 conversion. he used the standard ca18 engine mounts made custom gearbox mounts and custom tail shaft and besides that it was just a bolt in affair, the extra exaust yes to change to the other side but he saved plumbing in plumbing cost as he didn't have to do the run around in the engine bay. as to do with the wiring bit more dramas hooking up the speedo and tacho but everything else cost the same with the auto electrician. you can check out the conversion via this link. http://www.nissansilvia.com/forums/index.p...howtopic=132278 just after some opionons as which way you would go, taking into account the half cut is an extra $300. the whole conversion will cost an extra $300 to do the whole thing. cheers

well seeing as though a rb25 half cut for a series 2 is around the $4500 without brakes, and a 1jz half cut with manual box is $4200 (working off quotes i have recieved) so i don't think it is as rediculous as what you think. i also got a quote from my mechanic that he would only charge me an extra $600 for installation for the 1jz compared to the rb25.

hey guys i know this is my first post but just wondering which motor you would prefer lets say for example in a s13/180sx just wondering which motor you would prefer both reliability and power production. And please try not to be biased. rb25det or 1jzgte cheers
