Throwing in my 2 cents but admittedly not well-versed in such things…but, I spoke with two highly reputable Z shops (in Houston/Austin) and both of them said that converting an NA engine to Turbo/twin is 100% an option and in some cases preferred over an NA to TT swap. Why do people say this isn’t possible? Surely this was even possible 10 years ago? It does feel odd that the internet 100% convinced me it was impossible yet the guys who actually do this work as their full-time jobs very casually stated that they’ve done it and could do it. (Not saying that it didn’t come with a price tag, but something to consider now that used TT’s are going through the roof)

The NA motor is higher compression, it will build boost more quickly and make more power at the same amount of boost. The problem is that the factory management isn't up to the task. Stand alone or a TT wiring harness and ecu are bare minimum you'll also very likely need to take a serious look at the fuel system. I wouldn't be surprised if it cost a few thousand dollars more then just procuring a factory tt.

Mostly purists who are like this. The same purists that actively held back the platform for decades. Meanwhile, we have actual builders in the community throwing out 800+ whp VGs on stock internals and breaking records by deviating from the norm (single turbo). Makes you think.

They don't. They say it's not economical, and more difficult to do correctly than what some people say. Many people do NA -> TT conversions on the budget, and they tend to not be around for long. Survivors are the exceptions, not the rule. NA to TT is a good option for someone with a deep emotional connection to a specific NA they have, and reasonably deep pockets. OP hasn't bought one yet. For someone shopping for a z32: if they want a TT, buy TT.

They do. “The NA cannot be converted to turbo” - quote from someone else on this post. I certainly agree that there is $$$ argument to be had when talking about converting to or starting off with TT, but this isn’t the first time I’ve seen someone state that it just straight up isn’t possible. Again, I’m not a mechanic or engineer so I’m just parroting what i’ve heard from the pro’s, but it is strange to me that this type of info is being tossed around. There are far worse things that someone could be spreading potentially false information about, but the point stands haha…it is possible.

It is very expensive to convert a na to TT. It is done by replacing the na engine with a TT engine. The compression ratio of the NA engine is not suitable for turbo application. Without geting into specifics, theres several other differences between the engines as well. The na cannot be converted to turbo. To do the tt swap, you are looking at a minimum of 10k. Its could really be 12k or higher. Considering the cost to do the swap, it may be worth it to spend more for a TT. I feel another good route would be an LS swap in an na 300zx. You can get similar power with less complexity. I know little about what's involved but I'm aware it has been done. I sawr a guys YouTube's. Its pretty involved and costly Any way you slice it. Honestly, you may want to look into a different car. A perfectly clean fourth gen Camero SS (1999-2002). can still be bought for 30k. Imo those cars will be worth close to 50k in 10 years or so. They have that 90s classic car aesthetic going for them . You should shop around. There's tons of really nice high performance stuff out there. It seems like a lot of hassle to turn an na Z32 into a faster car. Also, the parts are getting scarce and expensive.


AeolusZX

I've done this swap for under $3,000 with a combination of used and new parts. You and these folks downvoting me don't know what the hell you're talking about, lol. Also a LS swap would cost more than any NA-T build and make even less power. Laughable. Please get off of these old forums with circa 2000s misinformation and join communities like Z32 NA-T on FB. Thanks.


Zim_Lag

Could you point me in the direction of any resources where i can learn how to do it?


z32ttdude

How did you do the swap?


AeolusZX

I literally just sourced most of the parts from a factory TT that would be needed. It all bolts up to the NA motor without a fuss. You'll also need either a standalone ECU with a tune or a socketed ECU with an EPROM tune due to the higher compression. That's really the gist of it.


z32ttdude

Ok. Well, I'm talking about doing things correctly. You cannot simply bolt turbo parts onto and NA engine and call it good. I guess you can, but it's not going to run worth a damn. I have no interest in looking at a FB group where zoomer kids destroy 300ZXs with horrid turbo modifications.


AeolusZX

Yet that's exactly what it entails. Do your research.


Corn-Doge

Tunes gotta be very on point for the higher compression but it’s doable.


AeolusZX

Yep, Zshack did mine. Very reputable shop.


AeolusZX

Pretty easy, but you'll want access to E85 or be forced to run solutions like methanol injection/octane booster. Source the relevant parts from FB groups maybe: Downpipes, stock turbos, oil pan, bigger injectors, bigger fuel pump, stock intercooler piping, stock intercoolers, TT radiator, TT clutch and flywheel, TT accordion piping, etc etc..

Cheap car fallacy.


Fooly1983

Their are a multitude of options ranging from many different price ranges. You can buy cheap turbos from ebay and turbocharged the factory NA motor pretty easily.. you wound just need to send the factory ecu off to be modded as far as the ECU is concerned. It isn't too bad to be honest
