dudes heres the deal

this was pointed out to me by a fellow zdriver
would this all work and what kinda hp gains and so forth could i expect with this set up in a n/a z motor? is there anyhting else i that i would need to modify on the motor to run a turbo?


thanks heeps

No fuel upgrades I would say gestimate of 250 if you crank up the boost, but I would advise fuel upgrades and a intercooler.

 

Is the turbo manifold custom made? Or is it one from a 280zxt, because those wont fit on your engine's head

 

It might make some decent power but if you turn up the boost it will just be a matter of time before the engine blows.

 

I am in the process of getting a tubular header made for less than 100.00$$ I will post pics if it goes well.

 

ok so for the basic turbo set up that is all id need yeh?

i mean without cranking up the boost the turbo kit would run fine and the like with the above mentioned components?

say i want to crank up the booste a little in the future, even with fuel upgrades and a FMI will my motor self destruct? because its the n/a not turbo motor?
what will be the weak points of the set up in the n/a motor with the kit?

thanks guys

 

The weakest link in your motor(assuming everything is in good shape) is going to be the pistons. But as evidenced by s/c's post, even those can handle quite a bit if detonation is kept at bay. But with the stock pistons, your compression will be too high for cranking up the boost. You could kill two birds with one stone and just upgrade to aftermarket low compression pistons. Then you could run considerably more boost. If you're not planning on too high a number a cheaper alternative is to go with the OE turbo pistons which will give you lower compression and allow you to run more boost. And those can handle a bit of power thrown at them. Neither motor is any stronger than the other, although the later blocks had better coolant circulation around the cylinders. It's just that compression ratio that's going to get in your way with an NA motor. But like I said, you can easily get over that little hurdle.

 

Oh, and if you're really serious about making alot of power and you want your motor to last, you might want to consider new bearings and getting the rotating assembly balanced(you're going to have the moter apart anyways if you decide to replace the pistons). That way vibration doesn't kill your motor, which it will if it's got enough wear in it from high mileage or neglect. Plus if you spin or dislodge a bad bearing, you'll lose oil to that spot and then your nice motor goes kaput. This stuff can happen to any motor, but the more strain you put on a motor, the more likely you are to expose it's weaknesses. And with the substantial investment that goes into building up a motor, I'd hate to see it go to waste over something small that was overlooked and caused catastrophic damage as a result. GOod luck with your build up.

 

You can keep the NA pistons and get a 2mm head gasket, IC, turbo injectors and fuel pump. Tuning must be on point though. Should be able to do that with the microtech.

 

Yeah but a thicker head gasket is more prone to blowing when under high boosting pressures. That would be the cheaper way to go though, and would be more than adequet for a lower boost motor. But if he starts cranking it up, he'll be replacing those headgaskets more often than if he just throws in some low comp. pistons. Shortcuts will get you there quicker, but more often than not you end up hitting a snag that ends up taking more of your time (and money in this case).

 

I'm talking 2mm metal head gasket. These are made for high boost applications and seal much better than the oem gasket but I also would not recommend turning up the boost unless you REALLY know what you're doing.

 

Im pretty sure the N/A dished pistons and the turbo pistons are the same. The only difference is the type of piston ring and oiler ring that is used.

Pistolio, do you know which piston and head combination your engine has?

 

79 and 80 had the dished pistons. So if you've got an 81+ then you got the hi-comp flat top pistons.

 

heres what i got there fellas ive got a 83 turdbo and a 78 280 i put 4 gs into the motor.turbonetics t4, 30 over block ,decked,new oem pistons and rings balanced lower end complete with flywheel and cluth,biult p90a head with stock cam for now,300zxt inj,2 msd 43lbs fuel pumps blow off valve ,boost controller,and stock ecu,5spd.heres whats going to happen swapping motor from zx to z(car is just to heavy and im not a fan of the zx)replacing p90a head for thn47 big valve head.adding a isky cams 490 290 14deree seperation cam(as in my nitrious car)msd ignition with electronic retard box and a shift light ,and an intercooler from a npr ud turbo desil.with a jim wolf program and a set of 550 inj.plan is to make 550 at the back wheels

 

What boost pressures do you think you need to make to hit 550hp at the wheels?

Can you run those pressures on stock pistons?

What rpm's are you planning to run to make this kind of power?

What ECU are you using with the Jim Wolf program? (83 280zx or Z31?)

Are you sure you want to use an N47 head? Wouldn't an N42, P79 or P90 be a better alternative?

What's the flow rate and pressure drop on that intercooler?

Enquiring minds want to know!

 

tO HIT 550whp i WOULD GUARANTEE YOU WOULD NEED TO RUN AT LEAST 22LBS, AND THATS WITH A BAD *** MOTOR, AND PERFECTLY IN TUNE.. I DONT KNOW HOW YOU WOULD DO THAT ON ANYTHING OTHER THAN STANDALONE THOUGH..

 

Sounds like you're gonna have a lot of fun driving that one. Good luck.

 

As cool as 550 hp would be id be aiming to start with about half that and go from there

hmm now i gotta see if i can get my hot little hands on one of those kits

thanks guys

 

Sorry Lww :d

 

After about 350hp you'll hardly be able to keep the tires planted in any gear (with an LSD). If you want 550hp, buy a 300ZX Twin turbo and get out your checkbook.

 

I REALLY want to see a dyno sheet on this one.

 

I would like to see one also... I will definetly be posting a dyno sheet and find a way to post video when mine is done..

 

here's a guy that turbocharged his na engine.
http://www.cardomain.com/ride/330795/1
He somehow fitted the turbo manifold onto the n42 head

 

jim wolf makes a complete 450 horse kit for the zx turbo cost about 2400 bucks but worth it.got most of it working on the rest. 550 is with juice at a 100 shot on top of the turbo at 26 pounds of boost. and yes im running stock lower end.nissan put forged roda and pistons in the turbo motors from the factory.and the blocks are webed twice as good as the non turbo bloks.we also have a moble dyno guy down here that will come to your house if ya want .we do alot of tunning on the ls1 motors and such.but tit is a very abtainable goal if it is tuned right.al
