r33 gts turbo upgrade options

Here's my problem....

I'm at the stage where I have upgraded most of the basics. I purchased the car bone stock about 6 weeks ago, and so far the list of mechanical mods is as follows:

- front mount intercooler

- Apexi power FC

- Apexi AVC-R

- Blitz 3" system

- 3" high flow cat

- custom turbo-cat front pipe

- HKS air filter

- all running 1.0 Bar

and that's about it.

Now, I know I'm going to need injectors soon, as my electronics are giving me all sorts of warnings about high injector duty cycles, and I know that the lifespan of the stock turbo is limited at those boost levels. What I would like to know, is what sort of recommendations would you guys (my fellow forum members) recommend for the next stage?

I would like to take the car to about 250-300rwkw, and would like to maintain some level of everyday driveability (is that asking too much? I don't know).

What types of turbo should I be looking at, what sorts of injectros are suitable for the job, and the relaitve costs involved (ballpark figures are fine).

Thanks in advance for any feedback you might be able to offer. Before I get slated for not checking the archives or FAQ, I have, and couldn't find anything applicable to my question! I've had a brief look around on the web to no avail and thought I'd put it to you guys.

Thanks,

Simon.

your car is about the same level of mine.

my next step would be turbo.

-HKS 3040 unit is an excellent match. bit laggy but will get you the power you are after easy. water cooled too.

-external wastegate (the unit only comes with external wastegate)

-exhaust manifold (have to get it in order for the turbo to fit)

-injectors (size is up to you, around 700cc would do)

-custom plenum (to get the most out of the big turbo)

-fuel pump (you are increasing air flow so you will need an increase in fuel)

if you have money to spend (and it seems like you do) strengthen your internals too.

also don't make the mistake of ignoring your suspension as this plays an important part to your overall speed. many ppl just go for the go-fast-bits and forget the one thing that makes your car fun to drive.

goodluck;)

I've got over 300rwkw in my 33 gts25t... And if you want that much power, I can guarantee you that you're not going to get out of it without doing internals...

550cc injectors are good for up to 330rwkw, so I would probably suggest them as your best (ie: cheapest) option...

Scour the papers and wreckers for 2nd hand turbo kits (JMS etc)... You might just get lucky, I found a Trust TD07 full kit (ext gate, manifold, dump and turbo nice and cheap for my car...

- Budget around 8-10k for a decent motor build drive in drive out... You can do it cheaper, but in the long run, it'll probably come back and bite you in the arse... Oh, and don't expect to see your car for about 3 months...

- 2-8k for the turbo kit depending on whether you get one 2nd hand or new...

- As with what ONARUN said, spend some money on suspension and brakes too... It's all fun and games to have a car which accelerates quickly (hey, mine'll spin the wheels all the way to 160) but unless it can stop and corner just as well, then it's dangerous. There's about 2k for suspension, and the same again for brakes...

- You'll also need to factor in your ancillaries such as fuel pump, injectors, new clutch, z32 afm, cam gears, metal head gasket etc etc etc... These little bits and pieces can end up costing 4-6k as well.

- Custom Plenum isn't really necessary... I'm running the stock one on my car without too many problems... You might, however, want to invest in a larger throttle body...

- If your car is well built, and tuned well then there's no reason that it's not just as drivable as it is now. Don't listen to people who say big turbo's are laggy... They obviously haven't driven a properly set up car with one. My car starts to make boost as early as 3000rpm, and by 4000rpm I've got over 190rwkw. Which is more than what most of these guys have at redline. Your given the impression that it's laggy because there's so much additional power available.

My car is more drivable now, than before I did the upgrade with my small VG30 high flow... It makes more power at any given rpm than my old setup.

As you can see, the costs very quickly get up there... You call a place and get a quote on a motor build, double the quote. You'd be surprised how many little things pop up along the way (which initially seem insignificant, but when you add them up they start getting expensive).

Not many people end up going this far with their car (Although they talk about doing it) because the costs are so high. For a reliable 300rwkw, that's what it's going to cost you.

For 250rwkw, you might be able to get away without having to do the motor, which'll save you big $$$.

Thanks very much fellas for your informative and comprehensive posts. It is certainly food for thought.

I'll take your advice on board and let you know which way I go.

The points you've made are all sensible, and I understand what you're getting at.

Thanks again.

Simon.

Kirby - u asked where I got all the mods from....

firstly, I live in brisbane, so this info may be pointless, but here goes:

fmic - purchased kit from ARE (www.are.com.au) $2140, fitted it myself

power fc - bought it off ebay for $1650 incl hand controller, fitted it myself, but got it tuned properly by Chapman & Chapman (Woolloongabba, Deshon street)

afc-r - purchased, fitted and tuned @ C&C (as above)

front dump pipe - Custom Exhaust Systems (Geebung) $675

HKS filter - jap spares in sydney via internet

high flow cat - C&C about $200

blitz cat-back - on the car when I bought it.

hope that helps. I have phone numbers / websites for all of the above if you want them. I'd have to look them up, but let me know if you need them.

Cheers,

Simon.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
