Removing Turbo

[ke70+ae92]

hey

i want to buy a r32

ive been looking around iand ts hard to find a non turbo one and when u find one there more expensive then the turbo ones

how hard would it be to buy a turbo r32 and take out the turbo and how much would it cost to do

i would have to replace the ecu with a non turbo one and get a non turbo inlet and outlet manifold.

any advice would be really appreciated

thanks

If you do the work yourself it shouldnt be too expensive..

You need;

Intake piping

Exhaust mani/Headers - I have a stock exhaust manifold if you are looking to buy.

NA ECU.

Now the problem is compression ratio. The last thing you want is a low compression 2L NA.

You could always take off the head and shave the balls off it to get the NA 10:1 C.R. Or shave a little more and run a higher CR to give it more poke. Say 11 or 11.5:1. I figure if your taking off the head you may aswell.

Thats about it.

But why buy an NA R32 when there are so many better NA options available?

thanks for that

ive always liked r32s and always wanted to get one

i was also looking at buying a na rx7 series 4 or 5

but i didnt want to take a risk and something to go wrong with the rotory and have to pay for a rebuild

whats the difference between a non turbo head to a turbo one

[scathing]

The compression ratio of your RB20DE-T (as well as various flow characteristics of the cams etc, which I don't know is the same between NA and FI) isn't your only problem.

The gearing is completely different between the turbo cars and NA, so even if you pull apart the engine to increase the compression ratio and get its efficiency close to NA, the thing is still going to run like a dog. Theoretically you could just replace the final drive and leave the gearbox itself as-is and you'd get most of your performance back, but there's another expense.

For the cost of doing what you want to do to an R32 GTS-t, you could have bought a good car.

Also, its also debatable whether its legal for you to drive it. Some people have called the RTA, who've said its OK to take the turbo off, but a guy I know called the RTA who told him it was OK to drive a 350Z on his P's without an exception, even though its clearly marked in the banned list.

The wording of the rule is that P platers cannot drive cars where the engine performance has been "modified". Note, it doesn't say "increased", just changed from its factory specification. If your car is meant to have a turbo and doesn't, the performance is no longer the same as when it rolled off the factory floor. A "letter of the law" interpretation says the car is therefore still not P plater legal.

If a cop's in a bad mood, its a reasonable interpretation as an excuse to ruin your day.

try to find a RB25DE R32. there should be a few around. more common these days with the new laws and such. plus the extra .5 ltr capacity will be awesome

I don't know about 32s... but 33 na's I believe have slightly lumpier cams? don't quote me on that though. also, as everyone has already said... compression ratio... not to mention the pistons will be a little bit of a different shape as well... the turbo ones have a lump ontop and the na's are flat..(also from memory)... to be honest... its not worth it.... you will be spending that much money for absolutely 0.

if you do do it.... and you don't increase compression and all the rest of the crap... excels will flog you... it may be nice to say you drive a skyline.. but driving it would be horrible! just wait till a good na comes around. you will be much better off... or look at na silvias... 180s.... 200s... dont just limit yourself to one na import cuz there are heaps of other na imports!

yeah this would be more effort and expense than its worth

get a beater and then a turbo skyline later...

i was looking at the same thing too but with a r33 cuz i want to put the turbo back on when i get my full licence..if money is not an issue then whats the downside?

In all honesty, you're better off just waiting until a suitable NA pops up, then selling it when you're ready for a turbo. Once you start pulling apart an engine, unless you're building up it lets all the gremlins in.

Im still gonna get a quote on the job anyways to see what price they reakon

[WIHAGTR]

It's pricey and probably overall not worth the hassle in my opinion, plus r32 engines in today's age, unless properly looked after die off :-(

removing the turbo and running it atmo is not easy, cheap or practical

its probably much cheaper to get an atmo then dump in your favourite boosted donk...
