How do the power and torque characteristics of the Z's engine actually alter with tuning?

 

Say for example, I popped an induction kit and exhaust on my TT, would it go all top end? or would i still have a nice wide power band?

Induction kit + exhaust will significantly increase your midrange torque. Get a chip to manage the increased air intake and you won't be sorry you spent the dosh! I can do all three - A'PEXi induction, Mongoose exhaust and DTA chip - give me a shout if you're interested.

What sort of budget we talking about for this? I'll have to start saving all my pennies...

have a look in the traders section dta motorsport

 

induction kit approx £120

mongoose exhaust approx £500

chip not sure of price check DTA for info

and you'll need a boost controler

Seems very reasonable. What sort of gains would all this give, typically?

 

Any implications regarding extra power through my auto box or other parts of the car?

I also posted "whats a boost controller"

 

Still dont understand what it does and what its for.

 

Can anyone help?

A'PEXi induction kit: £85 (+ £5.20 special delivery)

Mongoose cat-back exhaust: £510 (delivered) - choice of two tip designs

DTA-Motorsport Performance Chip: £65 (+ £5.20 special delivery)

 

Boost controller: an electronic device which allows the user to set various levels of boost. The controller achieves this by manipulating the waste gate actuators. This is a safe way of increasing boost levels. An A'PEXi AVCR or Blitz SBC ID are examples of good boost controllers but cost several hundered pounds.

 

You can also insert "boost jets" into the lines that feed the waste gate actuators. These are typically "mig" welding tips of various aperture which allows you to arbitrarily set the level of boost. This method is prone to "spiking" and is not recommended if you're interested in chasing serious boost increases. Having said that, DTA-Motorsport are exclusive dealers for custom made boost jets which have been professionally engineered to minimise the spiking effect. The apertures are custom drilled to the customer's requirement and the kit includes stainless steel hose clamps, the actual drill bit used to periodically clean the boostjets and fitting instructions. Price TBA but will be in the region of £36 + postage. Available in the next two weeks.

 

Hope the above helps.

Thanks for the tips, guys.

 

Will the standard auto box and diffs and stuff cope with tuning such as this?

The Diffs on a 300zx are said to be almost industructable. However the auto box is not, this should take upto 350-400 FWBHP but it will shorten its life. You can get it uprated at a cost of about £2500 i think and that will be good up to about 500-700.

 

Also if its a Jap import then you NEED to fit a bigger autobox oil cooler.

Depends on how old your car is and how well looked after it is (all servicing done etc.). If the car is in good nick then it should be able to handle a significant power boost with no problem (although it will break more often anyway when you start to push it harder).

If your car has definitely seem better days then stuff will break left right and center as you try to wind up the power.

Just make sure your brakes are good and the tyres have tread on them and then you wont die stupidly.

This may be an obvious statement but I can't reitterate it often enough ...

 

Don's spend your hard-earned-cash on altering the performance until you are absolutely 100% sure that the engine (and other bits) are in top form and performing exactly as they were intended to perform.

 

If you start modding "half baked" parts then you're asking for trouble - they will fail and when they do there is an increased likelyhood it's going to fail big stylee. Better first spend some money sorting out your engine, transmission and other bits before modding for power increases.

 

Just my 2p worth ...

Thanks for the tips all who contributed. One last question though....

 

Is there any mileage limit on an engine to be tuned? Or will any well serviced engine be suitable?

mines done 110,000 miles now, & has been running 16psi for the last 25,000 miles :)

 

its really down to the condition of the car & how well its been maintained. if its a dog thats had loads of missed services then a car with regular servicing thats been looked after but has twice the mileage may obviously be better.

?!?!?!? At some point of being a 300zx owner and being on here for 2 years I must have missed this?!? :slap: :slap: :slap: :slap:

 

Mmmm, never mind, manual will be here by the summer....

 

What can a standard manual with RPS Max Street Clutch take matt?

hmm, i think even with a fast road rebuild upto 700bhp on an auto is severely pushing it! besides - think of the power loss :D

lol, well I have mad emy mind up, Manual it is......

 

As soon as a manual conversion comes up, its time....

PLEASE tell me it's 250 for auto box upgrading, not 2500!!!!

 

And can someone give me an idea of roughly how much hp coresponds to each stage of tuning?

Poozer, it is £2500 for a fast road Autobox rebuild.

 

£250 might buy you one of the cogs......

 

If your new to the Zed scene then there you go, if you not then shame on you for even asking this question!! lol :D

Yeah I was afraid it was 2500. Oh well, buy a Z and be broke for life...
