I've been kicking around the idea of putting an engine from a 90+ Nissan 300ZX twin turbo in an FD. I actually have a spare engine and 5spd tranny so I'm part way there if I plan on doing it.

I know when people think of 300ZX they don't think of it being all that powerful but you can actually build them up to be 600hp with no internal enginemods done. With the stock turbos, some people have even gotten up to 500hp. They can produce lots of power for very little money. I have a twin turbo Z right now and I just love the power it has. All that has been done to it is intake/exhaust/ECU and it pulls harder than my FD ever did. I have drag radials in the rear (thanks Jimlab) and I still have a hard time keeping it strait, it's even an AT.

What do yall think? I'm taking out the LT1 in my FD here in a couple weeks to install my new clutch and flywheel. In the process I think I'm going to drop the 3.0L in and see how it fits. If all is good, I'll be on the look out for another FD to do a conversion on.

 

Arent those engines wider than an LT1, with the OHC stuff? A buddy of mine had a 300TT and it was probably the biggest pain in the *** to work on. They do make good power though. Save some change and try it in an FC there is much more room in there, and the car is just as light..

 

The engines are pretty wide. I think it'll fit though. I'll make some measurements tomorrow. Even though they are wide, the turbos are tucked in really nice so I won't have to worry about plumbing the exhaust manifold and stuff. Like I said, it's just an idea for now. I want to see how it fits in the engine bay before I go out and actually buy another FD to do the transplant.

They make awesome power. I'm taking a guess here but I think my Z has about 425 to the crank and I haven't even done much to it. Once I get some more fuel I can turn the boost up to about 20psi and I should be making some serious hp. If or when I get some upgraded turbos I'm sure I could get close to 600hp.

The only problem I see is the engine weighing too much. The Z32's weigh something like 3400lbs, I don't know how much of that is the engine and turbo stuff.

 

The only problem with the vee six is thats its wide, but maybe it will fit ? If I had the money I would try and install a RB26DTT these motors are so strong and can make high HP.

 

i was looking for V6 swaps and thoughts of engines
anyone think of this?


350bhp and 330ft-lbs, sits the rightway and people who have these cars cant drive for ****! possible totalled cars out there w/ "cheap" engines available
also its eaton supercharged so you can pull that at pop a t66 on easy!!! and say 15psi??

just a thought and picked this post to open the minds....

 

what ever happened to this nissan swap?

 

i have Ls-1 from a old corvette my dad found wrecked is it worth it to switch to the chevy motor?

 

I rather see a nissan engine rather than a gayward pushrod v8.

 

VG is good, it's not bulletproof.

 

2jzswap.com........................+1

 

This is a stock LS1 with just longtubes and a D1 Procharger at 7psi. Beaten on daily with 119k miles and still pulls hard all the way to redline.

Yes it is very much worth putting an LS1 into your Rx-7. Compact, lightweight, easy to make power, reliable, great fuel economy, anybody can work on them, and the ground shaking ability that is common with V8's, what's not to love?

As for the VG30, don't do it. I know 2 guys with the Z32's and working on them is a pain in the ***. The 300zx has a LOT more room in the engine bay than an FD and you have to pull the motor in order to access both turbos. A complete nightmare to work on. Not to mention much heavier than say an LS series V8.

 

vg's can support just the same as old 2jzs. around 600 on stock block.

Vg30dett has 8.5.1 compression with forged rods and pistons. CLose deck iron block. With 2 disco potatoes,injectors,EMs, boltons he can make sme real horsepower.

BUtGet rid of the gayward dual throttle body intake plenums. I have always hated those things . Because of those plenums it makes **** hard to work on.

 

Supra seven.

Dooeit.

 

The VG30 is a great motor. SpecialtyZ just released a new TT kit based on GT3271? I believe capable of 900+ RWHP. The block is by no means bulletproof, and it is probably not as capable as a 2jz or an RB26 for max HP and single turbo kits have been hit or miss.

things that would make it worthwhile would be if it fits width wise and if it is enough shorter than a 2jz or RB26 to avoid the bump steer problems. It would be a better choice than an LS1 IMO if it fits, but I am somewhat partial. I doubt if it's any lighter. People think Z32's are a pain to work on but they are really pretty easy if you know what your doing. The Z32 suffers from the same over engineering as the 300gt. once you get rid of some of the ancillary systems in the Z32 it looks a lot less cramped. A stock z32 has like 26 feet of intake tubing I think and 30+feet of vacuum hose.

Another bonus is VG30's are cheap. JDM's run for 13-1500 with tyranny although I probably wouldn't put one in my car. Great built long blocks can be had at great prices from the most reputable vendor in the Z32 community Kyle Puckett at ipp. wwwDOTimportpartsproDOTcom (First post no links rule)

I dont even own a mazda but I routinely peruse on this forum because I baby my Z and eventually I'd love to have a toy to abuse at the track. FD is my top candidate at the moment. Also I realize this sounds overly cliche but I apologize if I sound like a retard, My rule about forum posts after drinking has fallen by the wayside apparently.

 

The new toyota swap is a 3sgte I think I'm not to sure but it is a inline 6 from a lexus and everyone is using that motor instead of a 2jz...ill find more info...or you can get a lexus v8 those are bad *** and throw a itb kit on it and maybe a twin turbo set up and you'll be good...

 

^^^ 3SGTE is a 4 cylinder. I think youre referring to a 1JZ.

 

i have the tranny 2....im gonna have to look at my current motor then if its junk im gonna look into getting tht Ls-1.

 

Did some research...2jz allday baby!!! Lol

 

Can i just add the fact that VG's have a GREAT power band.

Well i never drove a VG30dett but my ex z31 vg30e-t WAS sick!

 

So much LS1 bashing in this forum it is funny to me.

 

I would love to see someone come and drive my car, in any circumstance (road race, autox, drag, freeway roll, daily driving, etc.) and tell me the engine is the weak link, is inferior tech and worse than a heavier, more complex, less efficient engine, that has 'more technology'. I thought technology was all about doing more with less? Sure there is more displacement, BUT the engine is smaller, it makes more power with less air and fuel, AND makes that power sooner in the rev range...

A stock engine posted above on 7 psi makes 450ft/lbs and most in this thread just totally dismiss it.

 

That's how it goes man. I now have 120k miles on the motor(13k of it is with boost). Ran a bolt-on C6z from 30-130 and was dead even, and still get 29mpg at freeway speeds with 91 octane **** water gas.

Currently looking to throw in a front mount and a smaller pulley for 10psi and get 550rwhp/500rwtq.

 

personally i would look for a SHO V6 and twin turbo that but the VG30ET is a very nice motor though the DETT version is an interferance motor,
