ok.... im STILL in debate about what to do.... i just cant afford a tt.... its hard to find one around here for less than $10k... plus the fact that im only 16 makes it almost impossible... i only have about $5k to spend on a car (besides the money ive been saving for insurance)

ive been thinking... why cant i get a turbo upgrade kit like the JWT Sport 500 turbos and get a manifolds and intercoolers and all that from a junk yard or parts car.... then buy a new ECU?

thanks

It's way more complicated than it sounds to turbo an N/A engine. Plus it's a lot more work than just doing the engine conversion. From what i hear, the n/a engine has such high compression you would only be able to run like 7psi, compared to a 15-20 psi with those sport 500s on a TT engine. it's really not worth it. PS those sport 500's are JUST the turbos, not a turbo "kit" If you look hard and have patience, there's a TT out there for you

Wait, are you saying that the N/A has higher compression that the TT? That doesn't sound right, but I could be (very) wrong.

The NA has higher compression. The turbo motor has less compression because less is needed due to the increased air density created by using compressed air via forced induction.

you can get a front cut for well under 5k, turboing the n/a engine is a more intermeidate project than the swap, it can be doen if you knwo what you are doing.....no offence but, it would appear that you do not

you have 15k total to spend and can't find a TT? are you blind? they are all over the place, you can get a decent TT for about 10K and still have money for mods, are you trying to buy one with under 60k miles or something? are you looking for cars more than a mile from your house? for 15k you can get a 350Z

5k not 15k

Buy an NA for now and be happy with it.

When you can afford it, buy a front clip and swap the TT motor into your NA or sell the NA and buy a real TT

OK, I can sort-of understand that, but then, well crap...

Why does the N/A require a lower Octane than the TT?

(iknowididntwanttogetintotheoctanediscussionhereagain)

I "thought" that a higher compression required a higher Octane Rating. If the TT is Lower, it should be able to run a lower Octane than the N/A...

por favor to esplayen... (That's my Mexican Lingo...)

Forced induction = more pressure in the cylinders. That's the whole idea of forced induction (forcing as much air as possible in) and thus you need higher octane.

Its a very simple thing actually.

Also, I realize that a lot of you are new to Z's and have a lot of ideas and question about what if or why not....but Z's have been modded for years and years and we (the Z guys who have owned them for a long time and others who we know who are in the same boat) have tried just about every scenario whether it be superchargers, turboing NA's, running 20+ psi on stockers, spraying a ton, etc etc. So trust us when we tell you something. We're not trying to be ***holes or discourage your ideas. We are sharing knowledge, which was learned the hard and expensive way many times.

I believe you, and trust you

So does the N/A require a higher Octane than the TT? Does the TT have a lower compression ration than the N/A?

The NA has a higher compression ratio than the TT. But, as stated, turbos force air into the cylinders thus more densely packing in the air and adding to the volume in a sense and thus more is compressed. I'm trying to keep this as basic as possible so not to confuse. You understand how compression ratios are figured and how forced induction functions correct?

Yeah. And I am NOT trying to be a smart ***.

(Forced induction should increase barometric pressure in the combustion chamber, thereby increasing the compression ration. Since the compression ration is increased by forcing induction, pump gas will also be more likely to pre-detonate. Having said that, it is also important that Octane ratings be increased to avoid pre-detonation. Therefor, Twin Turbos tend to have a higher compression ratio, and need a higher Octane rating!)

I HONESTLY want to learn! I was just confused when I read that:

And that just didn't sound right to me....

Ok well how about this....before the turbos pressurize the cylinders, the TT has a compression ratio of 8.5 : 1. The NA has a compression ratio of 10.5 : 1 all the time. Thus both should run premium but the TT really has a need for it once in boost.

I read too fast, I thought he was buying a car for 10k and had 5k to spend on mods, few TT's can be had for 5k, but you'll spend more in the long run fixing all that ails them, better plan start with a better car, best plan at age 16, stick to the n/a and learn to drive!
