Hey all, Ive had my 93' 33 gtst now for about 2 n half years n its boring me. Ive been waiting for the time n cash to do it up a bit, now i have it(soon).Would this be suitable: 600hp+ turbo, new h/d clutch, f/m cooler, microtech ecu, bigger fuel pump n bigger injectors. What size injectors n pump are suitable? Is there something else i need? Ive got a 3.5" exhuast right through already n thats it, the rest is stock. Ive been out of the scene for a while n need updating if im missing somthing people are putting on to theres these days. This is n still will be daily driver.

Cheers for the feedback.

turbo is too big IMO for stock internals. also wont come on boost until probably 5000 RPM.

biggest turbo I would recommend would be GT35 rated at 500HP, even then would probably be too laggy for a street car.

ok then, apparently this particular turbo i was "gunna" get was an 'ATR45', i dont know anyhting about them or heard of it. Ive been told it was rated at .70 - 600+ hp. It is going to be dyno tuned so wouldnt they be able to do somthing about that then?

How much approx is a gt35 turbo n piping going for?

sorry, you said that would be too laggy aswell. Can any1 gimi as yell on a good turbo n housing (not piping) for me. I want somthing that is going to be strong n powerful that will be worth getting for the other mods im getting

not much you can do to tune it to hit boost earlier.. advance the timing a lil maybe but it can be risky..

that kit looking at $3.5k+

hks gt-rs mate.. or just go hi flow if you want to save a bit for somethings special..

Hope im not sounding too dumb but id like the car to boost up still about wot the stock one does. The hks would do that would it?

Go for a HKS GT-RS or a Garrett GT2860RS (Disco Potato) for a quick street RB25, thats what id do anyway.

You will lose a little bit of low down response, but gain loads of midrange and top end.

Or if you want even more lowdown response, but a bit less top end, just mod and high-flow your current turbo like whistle said.

Have a look in the RB25 dyno thread, thats the best way to work out what you are likley to need to suit ur needs.

Hi there.

I notice your new to the forum.

If you read the Dyno Sticky thread at the top of this section, you'll see results from many various turbo setups.

Golden rule is - more power you want, more lag you get. A 600HP turbo is never going to come on even remotely close to a stock turbo, yuor talking 4500rpm or there abouts

Have a read of the sticky thread, and also the FI Guide (just below it), once you see a setup you like with a turbo that seems to fit what you want, have another search with that turbo. Plenty of threads detailing HKS GT-RS, Garrettt 3071/3076, Trust TD06/TD05 series and so on.

Thanks

    • At this point I'm just 'hoping' it's the turbo seals. I did speak to someone who said it's normal for these turbos to have a bit of axial play? Not gonna lie I've never checked a turbo for axial play before but you could hear it tapping a bit as I moved it back and forth. Surely that's too much? My theory is (could be completely wrong), bad axial play, worn bearings, bad seals, oil into dump/compressor side, burns in exhaust = blue smoke. On a timing belt related note, my crank pulley was missing that front plate that sits in front of the timing belt. It's that metal round plate. It did have the rear one, and the woodruff keys are in the crank which was nice. Can anyone confirm if the NEO det engine has a front plate, im sure it would to protect the front of the timing belt or something. Water pumps...the pump I got was an NPW (yes grill me if I should've got a genuine one lol). It has a smooth mating surface, kit came with a pretty pathetic looking paper gasket. Do I need to use any RTV or just trust the gasket will work because its a smooth mating surface? Cheers legends have a good Easter break!
    • Cheers man, I thought the same.   Bit of an update on it all. It was definitely blue smoke, not grey after all. It didn't really smell oily but it was blue after all. Also puffing just the smallest amount on idle with no throttle.   I ended up pulling the intake and exhaust off and there was around 3mm of axial play on the turbo shaft. So I figured we'll that's buggered and sent it off to get hi-flowed at hypergear. Haven't got it back yet.   I haven't compression tested it yet. Had a look in the cylinder and cylinder 1 spark plug, looked a bit sooty but not oily. Then I've just started doing my timing belt because it's age is unknown.
    • In that case it is probably stock. It lives in the navigator side footwell behind the plastic trim just in front of the a pillar.
    • Good question, I don't really know tbh...I'm pretty stock thought, where could I check this?
    • This. I'm confused by the whole discussion. The only reason you would have a car with e85 only if it was track use and you only ever used e85. All other use cases you add a flex fuel sensor, do the flex tune (you only need to do a couple of % and then interpolate the rest) and then you put whatever the hell you feel like including a mix in the tank and it just works. Want a long drive? fill with 98 Want max zoom? fill with e85 Got a half tank of 98 then find e85 somewhere? Throw it in.
