Ok guys my car is dead with a capitol D... the main crank bearing went on me... only had it running 3 days... But there is light at the end of the tunnel. A buddy of mine found a 300zx TT motor for 200 bucks runs great.. no turbos with it though only bad thing. i was wondering what kind of hell i would have stuffing that in my engine cavity... its a 88 max with a 5 speed. nothing special. any comments or ideas would help a lot.

 

The 300ZX TT motor won't fit, period. The twin cam V6 won't fit in a 2nd gen.

I second this your best bet would be to put in a vg30et from a 1988 300zx turbo. Same engine as 88 max just with a turbo. Thatd be youre only best bet for turbo swap in motor for our cars. Or if you want N/A either an engine from an 88 max or non turbo 300zx would work fine.

 

You'd have to rearrange a few things to get the VG30ET to fit, it won't drop in plug and play. You have to realize that the engine sits vertically opposed to horizontally from the 300ZX to the Maxima mounts.

Read more about it and just take the directions backwards.

dude my engine Died 3 months ago so i decided to do the swap... still geting it done though its not hard just time consuming... its pretty cheap to ... I decide to do a little more then just the swap trying to go 1 step ahead and do some hardcore machining my car should be up around feb or jan hopefully when im done ill show yall the pics

 

Glad to hear you 2nd gen guys getting serious about the vgt swap. a few 3rd genners are in the process too. You guys have one up on 3rd gens. Your engines are closer to what was in the vgt cars(z31 here in the US) You can use the vgt injectors, where we can't (different feed arrangement, the TT ones work, but way more expensive). A big advantage. In case you didn't know, the vg in our cars, as with all vg30's, turbo or not, have the same crank and rods..very strong ones at that. The main diff between the VG30 and VG30T are the pistons..lower compression. But if you guys swap injectors, use the turbo manifolds, ECU, and put a nice size IC (water would be cool) and go with a bigger fuel pump, you're in business. Someone correct me if I'm wrong on any of these accounts. I only have a little experience with 2nd gen engines. Anyway, I can't wait to see the results. I'l be starting my VGT buildup sometime next year.

 

I have run across an excellent deal, but i don't have the damn money for it, or the equipment to do the swap. I ran across a 100k vg30et with turbo and ecu, with 3 mo waranty on both, for $700...

They said I can secure the engine/ECU combo for $250...and I'm working on possible bartering some computer work in exchange for the "deposit". Even then, I have to either find a shop that cando the install, or find a way to get my hands on the equipment to do it.

 

That's a damn good price for a complete setup. I'd just buy it whether you have the equipment or not..it's the first step. You can get a cheap engine stand for like 75 bucks and freshen the engine up while you figur things out. Do all the planning first, then worry about shoving it in. If you forgo the intercooler, the install is not that difficult realy, a cherrypicker engine lift can be rented, the hand tools a re things you should have anyway. So there it is. If you get it, put a T-belt, tensioner, waterpump and that should do it, but I'd at least put some turbo cams in it if you don't plan on going deeper. If of want$$, get waist deep and change the bearings, get the heads all done up, stuff like that. USe TT rods and pistons. You know the deal. What are you looking for? 275 HP. If so, you can do it without an IC and keeping the internals stock. Even at 100k, these VG's are reliable for this kinid of stuff. If you want 300+ HP, then I would consider doing some motor work with the engine on a stand. Tha's my plan. If it falls throught and you can't get it, e-mail me the source. sirmichael69@hotmail.com I'm interested. What year is it out of?

 

JWT has a package that you can make it go to 450 hp everything listed should be somewhere on this site do a search here somewhere.

 

before i send by heads to get machined and ported and polished ..can are blocks run with dual ohv? would it be hard to convert it because im looking at my head now and the intake ports look pretty normal size but the exhaust side size is ****ing way small too small for our engines

 

Technically, you can run the DOHC version of the heads vs. the SOHC. There is talk about clearance though for the hood.

I was thinking if it was able to be done the clearance could be eliminated with that wide body kit thats for our cars. It comes with a raised hood but thats if you like that kinda look. It doesnt look too hip to me though. But its an option out there.

 

Actually, the exhaust ports are exactly right. Seriously, nissan did a great job engineering this engine. That's why the power gains from a port job on our heads is not a whole lot, just a few hp. Opening them up couldn't hurt, but polishing is more important..keeps them clean and smooths the flow. I wouldn't bother with the DOHC setup...your are talking MAJOR custom work, trouble shooting etc. You might as well just swap in a vg30DE or get a new Max that came with one!.

Just do the heads right, valve job and such. Be careful milling the heads though, take as little off as possible. I will raise the compression (no big deal on VGT, as it is low comp anyway), but it changes the distance between the cam and the crank, thereby changing the cam timing..too much and it will run like crap. Plus, fitment betwn the heads and the intake becomes an issue and leaks form, especially on boosted engines. Check out Paeco. They do great work as far as I know. Plus, they can put in custom cams, and best of all, they can install larger valves.. a big plus on a boosted engine. I would just to the exhaust valve though, as there isn't a ton of room for the increased diameter of both valves, plus it's already boosted so it doesn't need a whole lot of intake work, focus on exhaust.

 

Welp, that option has been shot down. The wife decided she'd rather I just get the original engine rebuilt - now if only I could find some cams!

As for the price on that engine, it was misquoted to me, but the owner was going to stand behind the quote, for me only. The actual price for the engine and ECU (no MAF - already sold!), is $1000, plus tax and shipping...

There are cheaper on www.car-part.com

 

 

you can use infinty Q45 injectors also
