N/a To Turbo Conversion

[NISZILA]

Hey guys

I have a series I R33 GTS. I want to do a turbo conversion and have always had the idea that I would buy a GTSt half cut and do a whole engine, gear box etc. swap.

I've just found an opportunity, however, to buy an R33 turbo, actuator, elbow and manifold. I know I will still need a couple of other bits, i.e. fmic , but I was wondering if I should forget this and stick with the idea of doing an entire engine swap with a half cut, or wack the turbo on my current engine.

A few things to consider

1. The gear box is different between the N/A and turbo. How much will this effect me?

2. Tuning the engine. Is it worth the hassle of getting this engine working with turbo or would it be easier to wait and get a half cut.

3. Cost, which is the cheaper option. I don't want a dodgy conversion, but I would like an idea after everything what is best.

4. My engine is just short of 140,000 k's, so its not too old, the turbo had done 70,000, so not too bad either.

5. Is there anything else I need to consider.

Thanks heaps for any info

R33-GTS

BTW, I did do a search and hav read the N/A to turbo conversion threads. I just need some more opinions

Alot of people will bag you for this conversion.

Firstly, are you on your P's or have a licence that is power retricted in any way ? - If so....... Wait.

If Not....

Go the front cut. By adding a turbo too a non-turbo car is dangerous. You need the whole braking package, ECU, stronger engine internals, diff might even be different, gearbox will matter...etc etc etc.... With a front cut, you'll get 80-90% of the parts you need in one bundle.......

I have read that entire thread as well as some others. There are many valid points and things to consider. As I said in my initial post, I have always been thinking that I would get a half cut, I just wanted some more info or opinions on the points I posted. I know about getting stronger internals etc, but the main reason why I was considering this is due to the N/A compression ratio. It means that with a turbo it hits boost pretty much instantly and pulls hard even at low revs. It can work provided you only boost to about 7psi. Any more and pistons will fry. Just trying to get more info and opinions before I make any decisions. I could get the gtst pistons and the compression will be able to handle greater amounts of boost.

No I'm not on my P's or have a restricted licence. I'm 23 years old and got my licence at 17. I don't think I'm some superman driver or anything and I didn't buy the car because I saw it in a movie. I know a lot about the engine and would like to do most of the work myself where I can.

I bought an N/A R33 because I'd never driven a rear wheel drive before and wanted it to be a stepping stone rather than get into something with more power and not have my driving up to standard. I'm used to the rear wheel drive now that I've owned the car for a year and just want to do proper research before I decide exactly what I want to do.

Sorry about the rant. Just trying to get as much info as I can
