What can i do (aside from fit turbos etc) to increase my power in a N/A.

 

Im a total newB and the only things i can think of would be aftermarket exhaust and a Induction kit of some kind?

 

Can anyone recomend a induction kit for the Z?

New headers are apparently the biggest single power increase for an NA.

this was done just the other day. Intake, exhaust, decats, underdrive pulleys, ecu chip.

Apexi is probably the best induction kit.

 

An exhaust is a good mod and headers too.

 

A ECU remap would be worthwhile and an underdrive pulley.

 

 

Otherwise it's nitrous, porting or other expensive stuff I think.

Check out the NA tuning forum

Quite afew posts on there about NA tuning, strangely enough!

Thanks guys

Yep, definatly the Apexi induction kit....then ECU, decat, headers, Lightweight Pulleys & Flywheel, Headwork, cams, Overbore pistons, TT injectors....... SWZ are investigating a Supercharge kit and single turbo conversion for the NA too

What are the best websites to buy stuff off?

what bhp gains would you usually expect from this lot?

Coz is xtremely fast and helpful.

Here are few nbrs from my friends Z

 

300ZX NA a/t, 222 fwhp

 

Stage I 7.46s (0-100km/h) JWT Intake + ASP UDP 232fwhp 166kw

 

Stage II 7.15s (0-100km/h) AshsZ ECU 244fwhp 173kw

 

Stage II+ 6.9s (0-100km/h) TB tweak & timing adj 250fwhp 182kw

 

Stage II++ 6.86s (0-100km/h) RSM controlled gear change 250fwhp 187kw

 

Stage III 6.35s (0-100km/h) Exhaust + Own ECU mods 260fwhp 194kw

 

**********

 

I'll take my m/t z32na to dyno next spring and then I know my zeds hp. Mods are Apexi dual funnel intake, AMZ headers, custom made 2" free flow cat-back exhaust, custom made chip, egr disable and UR underdrive pulley. I'll make (during this winter) new pipes with free flow cats from headers to cat-back. More flow to my v6 air pump..

 

In the future I'll take the cylinder heads to the expert and at the same time the JWT mild cams will find their way into my cars engine. If there's 300+ hp after those mods, I'll stop the engine tuning and will focus to interior and exterior. It's going to be fast NA and it will look nice. ;)

I have done a lot of mods to my Z32 NA, it is posted on here:

 

http://www.300zx.co.uk/forums/showthread.php?t=85280

 

Here are the mods I suggest in this order:

 

Engine

 

1. Intake with tuned ECU (Jim Wolfe preferably)

2. Catback exhaust

3. Testpipes or higher flowing cats with headers

4. While the exhaust is off, install a 1-piece lightweight driveshaft

5. Lightened underdrive pulley

6. Electric fan

7. TT injectors (make sure you get your ECU re-tuned or you will run very rich)

8. Headwork, JWT wild cams (.272 degree regrind)

 

Of couse you will have to upgrade your transmission and suspension at some point (If I could start from scratch I would do the suspension mods first)

Before you add anymore power wouldn't a brake upgrade be advisable?

Few cheap mods to improve old 300zx lousy break response are brake brace to support brake master cylinder, ss brake lines, brake fluid change and maintenance of brake calipers. This made huge difference in my car and I also changed brembo drilled / slotted rotors for the looks ;) The "rubber" feeling is now totally gone and really car stops when you hit the brake pedal.

You might want to get some better pads but if your Z is a 91-96 NA you have the same brakes as the TT. If it is a 90 Z, you might want to upgrade to the 91-96TT/NA rotors and calipers, but really isn't necessary unless you are going to do a lot road course racing or you are planning on using Nitrous and could possibly put down more than 300Hp. :cool:

ooooooooooooooooooooh sounds interesting. can you tell us more? would be very interesed in the supercharge kit.

A single turbo kit might be possible but unless you are going to do some heavy modifications and tons of fabricating, I don't think a supercharger would fit. Plus, the gains really would not be worth it.

gains from a supercharger not worth it? Are you on this planet!?

Supercharger would be of a Centrifugal type and replace the standard Aircon pump (sacrificing aircon), taking direct drive from the stock auxillery belt setup. Pipework would be relatvely simple, no internal modifications needed, designed to run with stock compression at 6-8 psi.

 

The alternative would be a Twin-screw Supercharger Setup, but for that setup your talkng complete Upper (and probably Lower) intake/plenum replacement and Bonnet clearance issues.

 

Its in the later stages of Planning / Early development stage. No Power or Cost estimates at this time.

I have supercharged quite a few of my sports cars in the past. Unfortunately with the Z, you will most likely end up spending $10,000-$15,000+ dollars and countless hours on a customization that might get you 50-75hp to the wheels.

 

--For around $8,000 you can do a TT swap and get 80-120hp (depending on your set-up and skills)

 

--For around $6,000-7,500 you can call Rebello Racing in California and have them build you a 3.2-3.4L stroked NA motor that will put down around 60-140hp depending on your set-up

 

There are a lot of options you can go with that would IMO make a lot more sense, but if you have the money and do not care about cost, you can do pretty much whatever you want.

 

Does anyone know of anyone who has this set-up that actually works???

do you have any kind of timescale for the development? just wanna know if its worth hanging on to my money.

any news on the planning/development of the supercharger conversion legrath?

hello bud ....

 

just had a look at your "RIDE" and i think you should look at Brakes,spring's,shock's and handerling....1st .....you can have all the power in the world..but if you can't STOP or go round CORNER'S fast..you wont beable to use the power....IMHO.....

 

wozza...

definately mate. will have the braided lines and brake master cylinder brace soon and get slotted and drilled discs when i can afford em. i'll sort out the suspension as soon as i can work out what the hell i'm meant to do (suspension isn't my strong point!! any advice?). i was just curious how the development of the supercharger kit was going.

IMHO..go for brembo brake's ,tein/kyb's shock's full adjustable,front and rear strut bar's ,good rubber...;).......

 

but at the end of the day ..it's your money..!!!!! spend it well...;)....
