im thinking about picking up a set of megan racing springs just because they are the least expensive and offer the biggest drop. but im concerned about the spring rate. is it stiff? or squishy? the stiffer the better..:multi:

secondly, has there been anything done for a short shifter? has anyone tried cutting their shifter down a bit? lol just curious

what do we have in the way of tuning software? both for the ecm of the versa and computer software? if there was a program i could download to do my own tuning, i'd like to know about it.

has anyone bought anything from impul? i like their stuff but i cant seem to find a way to purchase anything off of their site. their contacts page isnt working on my comp.

has anyone played with the idea of a rear mount turbo? it looks like there is adequate space for it.. only real problem i see is fiting both pipes in our exhaust channel.. but it would eliminate the need for an intercooler and running a low boost set up would require very little done to the motor itself. Just a thought to play with ;) thoughts? comments? answers?

Cutting it will make the shifter shorter but no make it a short shifter if that makes sense :). Meaning the throw is not really going to be significantly reduced but just the height of the shifter. I have never seen how to take the knob off. Is it the same as older cars where it's screwed on?

You can look into UpRev for tuning. They have a tuners package I believe that will allow you to tune the car yourself. Other then that I have no idea what is out there.

There was someone else on here who brought up the rear mount turbo thing. There was a thread on it. I say go for it if you have the funds. An intercooler isn't really an issue. You can tuck a sidemount in the wheel well and it will be adequate enough for low boost.

Racingline Performance was working on a prototype SS, long while back, havent heard anything about it since. As for the rear mount, Squires Turbo Systems have made a bunch for muscle cars as well as universal kits for any application.

i've seen STS kits before.. and as i continue thinking about it, even though an intercooler isn't really necessary, it really wouldnt be difficult at all to put one in.. look under your rear bumper, towards the left side. if we set the turbo so that the intake was facing up towards the RL taillight, the filter would be (seemingly) higher than the filter on like the AEM cold air intake.. and there would be virtually no heat back there.. just put a turndown exhaust tip on the exhaust side of the turbo.. this seems VERY do-able and not that difficult... the hardest part would be getting the best tune i believe.. anyway, megan racing spring rates? a way to get hold of impul?

an IC all the way at the back of the vehicle would need a really long run back to the Throttle body. This is not feasible in my mind. Tuning should easily be handled by UpRev. I think if your serious you should contact them and see what they say. They have worked on several MR18's and should within seconds be able to say if they can make enough changes to the stock ECU to handle a low boost application.

well i was actually thinking of a front mount intercooler. running the piping from the turbo, up to the front mount intercooler, and up to the throttle body, that way there are still only 2 main pipes that run almost the length of the vehicle.

i contacted racing line the other day about it. I havent heard back about it applix yer up there maybe you can get them to prototype it on yer car if yers is manual i know they had it in the install manual blacked out but they never came out with it so i contacted them the other day maybe if enough of us contact them they will put it into production i just want the clunkyness gone in the shifter..

I never had experience with megan springs, but i know a bunch of civic and subaru guys with them. Good drop but horrible ride lol.
yeah thats pretty much the consensus with megan springs from what i've heard too.

dont know if the slightly lower drop is worth the worse ride.

thanks for the input guys. i'll be getting in touch with STS soon to try and see if i can have a rear mount turbo prototyped on my car. it would run in the vicinity of 5-6 lbs of boost, thus eliminating the need for an intercooler, and it eventually could open a door for the versa owners. i'll be keeping you updated ;)

Ok here is my .02 on the subject of turbocharging. Why not, instead of running a rear turbo, relocate the battery to the trunk. The combination of that and looking all the resonator boxes of the intake would free up enough space to run a small OEM turbo such as a DSM or old MR2, which is all you really need for 5-6 lbs of boost. Then you can run a small intercooler in the side of the front bumper. Problems solved other than the engine management and fuel. Dunno if this is the best idea, but it seems good to me. Just my .02.

i agree with ya on that subject when i relocated the battery in my truck it actully caused quite a few issues i dont know if that would be a problem with the versa or not but... im right there with ya on everything else man.

I wouldnt push the MR18 over 220HP or so, because it was not meant to do that. I feel with a small turbo like a Greddy TD035HL and a side mount intercooler, you could build a reliable, fuel efficient MR18 around 200HP that would be fun to drive but still practical for daily use. Greddy uses this same turbo in a Honda Fit turbo kit for the L15A with manual transmission. At 4 psi, it makes a 35% increase in power output while remaining efficient and reliable. If you figure the same gains in a Versa, thats a 42.7HP increase at the flywheel, or 164.7HP @ 4 psi. So you figure @ 5-6 PSI puts you around 180 @ the flywheel. Thats not bad. Just my thoughts on the idea lol.

jsanford, you seem to really know whats up with this. the constant problem i keep seeing, and i'm not sure if its possible, is the exhaust manifold. with it being on the wrong side of the engine (imo) it seems that there would be a lot of problems with the firewall. which is why i initially opted for rear mount. i'm pretty sure we have all seen the fox marketing versa by now, in which they relocated the battery box and such and they set up looked pretty good. but there was never a full release on the design aside from spectator pictures. got any ideas on a reliable set up? and as far as engine management, uprev has got it taken care of. i called and was able (after a lot of effort i might add) to get hold of a human being, who said that they would be able to send a tune that would handle it. they said they'd like to see a full dyno sheet before and a very detailed description of everything i'd be using, but the man was very confident that it was possible. i feel that the stock fuel injectors could handle the demand at that low of a boost.. thoughts? love your 350 by the way. what size rims and tires are you running? the rears look like 10+ wide 0.o
