I was wondering if the Z32 convert would be able to fit a RB25DET from a R34 Skyline? If it can what modifications would I have to make to the engine bay, and such?

Your thoughts, opinions, concerns are more than welcomed

Sweets

Well, I know a rb25will fit in a z31.

danogeno

do you think it'd also bolt up to the stock trans, or should i get the whole package... engine, trans, ECU and all?

GOOGLE my friend... Google. I typed in "Z32 RB25DET" and found A LOT of info:

these questions make me think your not very competent in completing this swap. a pointless swap in my and many other's eye. LOTS of money and time. hopefully you were going to have a shop do this for you. and you'd be MUCH better off useing a TT motor, or just selling your car and getting a TT.




any one wanna wager 1000 dollars this swap doesnt get done (dont take offense i speak out of experience)

danogeno

it was just a random thought i had thats all. and after reading a few forums seeing all the modifications that would need to be done... it would be cheaper to get another car that would be easier to get more power out of than a Z32 NA. that still doesn't mean i'll get ride of it though, its a blast to drive with the top down. thanks for everyones input.

soooo... who is gonna pay me 1000 dollars????

entropy31

your trick?

snwbrderphat540

good point where be dat hoe ^^^^

There's a guy on tt.net with an RB26T in his Z32 convertible... blasphemous. Why sacrifice 400cc just for an engine that's a little easier to work on. You can get all the power you could possibly use out of the VG30DETT and it'd cost less than an RB26 swap with the same power output.

There are so many reasons I prefer the VG30DETT.

zboost is finishing up a 25 or 26 swap into his z32

i've heard talk of a chevy 350 swap. does this actually get done? i'm not thinking about it, but someone said that they saw a kit or something for it and i just disreguarded it as BS.

ZLover4Life

That's been done at least twice. Once was naturally aspirated, the other was a HUGE single turbo.

KasbeKZ

that's crazy stuff. thanks though. i have been curious about that for a good while

lol what a waste

You know, on one hand I agree completely. On the other, though, at least he went in the right direction (i.e. MORE displacement and not less). If someone's going to bastardize a 300ZX, I'd much rather they go with a larger engine than an RB26 or SR20 (which has also been done). While the RB26 is capable of monsterous horsepower, so is the LS1 and it'll do it with considerably more low end torque.

But once you hit a certain power level, it starts becoming useless. The fastest Z32's all have GT2530's or JWT Sport 700's (both GT2860RS-based turbos), and thus have 600-750rwhp, which is easly attainable with the stock engine. (Greg Dupree - mid 9's on Sport 700's, Dean Delvy - 10's on GT2530's, z324u - low 9's on GT2530's, etc.) As a result, I see no reason to put these other engines in the Z32 (note: I fully feel that dyno queens are useless).

Sweets

haha he has his windows up doing a burnout

chevy parts and hoodpins do not belong on a z32, but at least it isnt a 2 seater, That would really be a waste

snwbrderphat540

see its fuuny, cause ive seen dupree's number's and now there are people that have dyno'd 1000whp with these motors. wth is their problem if they cant get good number in the 1/4 mile? are they that stupid where they built all power and dont know suspension setup or something?

b300z

the LSx is the only engine i would probably swap into the z32. but if i was doing that it would definitely make it worth my time, not just mod it to a stage 3 TT. and to correct the article...the LSx uses 1 cam

what? no 20Gs?

and thats why i wouldnt be interested in your z. i really like it, but those turbos are too powerful

ZLover4Life

Oh come on now... sliding the rear end out at the top of 3rd gear on stock width rear tires is fun.

I wouldn't get rid of the GT2530's for any other option on the market today. The only performance mod on my car I'm thinking of replacing is the old style Specialty Z downpipes with the new style.


There is a LOT more to building a fast car than making gobs of horsepower... look at the McLaren F1... a measley 627bhp (680 in the LM) and there wasn't a car that could touch it performance wise until Bugatti came out with that atrocity on wheels that needed 1000+bhp to do it.

When you mod a small engine to make disgusting horsepower, you lose out on your powerband. The big turbos needed to do big numbers don't spool fast enough, so all your power is made from 5000rpm and up. When you shift gears, you are almost guaranteed to land outside your powerband in the next gear... which means that you have to build up all that power over and over for every gear. Also, when that power kicks in, it's not uncommon for the car to spin the sh*t out of the tires. The result... a 12 second quarter mile time on a 1157rwhp Z32.

There are Z's with stock turbos in the 10's now (at least one)... and they're doing it with such comparatively low horsepower because the powerband is the entire RPM range. So when it comes to 400-700rwhp vs 1000+rwhp, bet on the 400-700rwhp car in the quarter mile. The four-digit dyno queens will own the highway once they hit 4th and 5th gear, but not much else.

But at least the Z32 dyno queens can be happy that they're not making four-digit horsepower with only 500-600ft-lbs of torque.

snwbrderphat540

lol, yeah my sig says it all. but thats why most motors that are making that in the drag rev out to around 9-10k now so they dont loose that on the shift. thrown in with a 2-step/anti-lag and that eliminates the problem. but the car is only usefull in drag races then. but then again thats still better than just making a dyno queen.

b300z

haha, i dont need all that power. if i had a z with those turbos, id be in trouble very quickly. they would be just begging me to turn the boost up.

plus, i want to try and push the stock turbos as far as they can go. get over 400 wheel with them.

ZLover4Life

Having the power on tap is actually more humbling than people would think. I'm sure there are idiots who would drive like asses, but I might go WOT once every week or two and it's only through a single gear (usually second). Knowing that I can tear the doors off most cars on the road is enough knowledge for me... I don't need to prove it to anyone.

snwbrderphat540

id do it once a drive. lol. but im still very conservative with my agressive driving.


what about the single turbo VG's ive never heard much aboot them..... id imagine it be neat you could run a much bigger turbo i imagine with alot less lag.... hmmmmm................ i need to sell my S30's and get back in a Z32.
