1990 Nissan 300zx 2+2 conversation VG30DETT

Hello fellow members,

I am new to this forum and the Nissan 300zx, so be gentle haha. Any help or direction in this forum would be awesome! I will be more than happy to help with info as began with my project.I recently purchased a 1990 Nissan 300zx 2+2 and removed the engine and transmission. I was hoping to replace it with a jap VG30DETT, I understand I will need to change the front and rear bumper due to the change to a turbo because of vent from the engine. Is this true? Anything will help. I'm getting the 300 painted this week and was curious to hold off if I need to get new bumpers. I have tried researching , but It has difficult for me. I'm pretty much gearing for a performance vehicle. Thanks guys!

You necessarily do not have to change the front bumper, it helps with airflow to the intercoolers, as the NA doesn't have any ducts for airflow other than the one to the radiator and condenser. The rear bumper are the same as a NA.

Thank you for the replies NissanFreak12 and Trimble Epic!
I have not gone through all the information in that link Trimble but I will look through it soon.
I welcome any ideas, suggestions, tips, comments, and concerns from forum members. I am looking to make upgrades that will help increase horsepower and protect the vehicle from newly added performance parts. I will post pictures of my project car. Looking at the Ls1 conversion in the near future with a 2+2 300zx.

CALLING ALL 300ZX 2+2 TWIN TURBO SWAP HEADS!!!'

After reading helpful info provided by Trimble Epic, Is there only one way to get a JDM TT engine to fit in a 2+2 by removing the TT front clip and transferring it to the 2+2?

Everything is interchangable between the TT and NA chassis with minor modification for some things. What exactly are you asking here?

From what I understand, If a TT engine will be swapped in a NA vehicle, the TT front clip will have to replace the NA's front clip. So the TT engine will not be able to fit the NA without the TT front clip? Pretty much at this point I need to see what kind of engines/transmissions can fit in 300zx NA. I have read a skyline, q45, ls1 engines/ transmission....... should work. I am trying to be as cost efficient as possible.
Thanks!

What are you referring to as the front clip? The only difference between a production NA and TT as far as the unibody is concerned is that the lower radiator support brackets are in slightly different places, that is all. A TT will drop directly into a NA shell and vice versa. You will need piping, TT rad, TT AC Condenser, TT PS Pump, and the rest of the TT accessories but the longblock itself will drop right in.

^^^^ This, except I would leave the TT PS pump out and use your NA PS setup. It also bolts right up. The only other part you might need is the Z1 lower rad support adapter. Also, while the TT engine is still out, its wise to ALL the rubber hoses and maintenance stuff.

^good point, I'm swapped and have always ran my NA pump. OP do some deeper research and you'll understand why, I was just listing off the things that are different.

Sorry for the late response fellas. I appreciate all the input thus far. The front clip I was referring to is pretty much the whole front end of a car. The link ( first couple responses) I was told to revise for the engine swap info advised for a front clip of a TT replace the NA's (If you search 300zx TT front clip on ebay there is a listing for one @ $900 before shipping). I guess because of the TT engine size or accessories. Good to know I can just drop a TT right in. It can be overwhelming with all the information out there for this swap. I have to cross reference many times, That's why I appreciate your input. Also I just recently put an ad up for an ls1 engine and transmission. I got a call back and would cost me $1,905 for both engine and transmission with 85k miles. It slipped my mind to ask if the ecu was included in that price? What do you guys think? That's roughly how much I was going to pay with an additional $3-400 shipping for the twin turbo engine/ transmission and ecu with about 40-60k miles. Thanks!

I will be posting pictures within the next couple days of the paint job the 300zx just got!

In the end of the day (if you do your own fab work) a properly executed TT swap and an LS swap will cost you about the same money. Your cheapest option is to sell your NA and buy a TT, if thats not an option for whatever reason, you have to figure out what you want out of the car and make the decision. There are too many factors that go into this decision for anyone to tell you what you need to do, anything you hear will be one person's opinion.

you buy a front clip because it includes most parts needed to complete a swap rather than sourcing random pieces and brackets individually. you don't cut the na frame off and weld a tt clip in.

a proper tt swap should have all maintenance and repairs done while engine is out. (efi harness, gaskets, fuel injectors, seals, hoses, do you really trust 20 yr old turbos???, 120k kit, etc, etc) budget $6-7k minimum. ive seen ppl try to do it on the cheap (literally just dropping in the engine with no maintenance work) only to pull the engine again to fix coolant and oil leaks or seized turbos.

cheaper to sell and buy tt unless you must have a 2+2.
