GReddy T67 info please

[ENSMR2]

Im looking for some info on the above turbo. I can get it at a nice price but cant seem to find much info on it anywhere. Even GReddy's site isnt much use.

Basically I want to know the following:

1. Power/torque outputs
2. Big turbo? / Lots of lag likely?
3. Is it ball bearing/thrust bearing/roller bearing what??
4. Any results with one on an MR2?

My other alternative is a Garrett GT3037 Ball Bearing Turbo - External Wastegate. Can produce from 500-550bhp. This is apparently highly recomended.
Prob is I'd have to get my own manifold and the HKS one is almost £1500 inc vat! The GReddy comes with one and wastegate for a better total price.

Any other manifolds out there for cheaper that will do?

I've decided Im def going External wastegate route.

Cheers guys,

Power outputs depends too much on other mods fella.

General guideline would be up to 450 at the wheels. Having said that I saw a US car with loads of head work revved to 9k make 360 at the wheels at 10psi.

[ENSMR2]

Sorry, Mods I've got and planning are :

2.2 stroker kit (steel crank forged pistons steel rods) 264 cams hks cam gears, HKS valve springs, Apexi intercooler with co2 spray, Head ported polish to maximum. light crank pulley, Big old injectors (prob over 850cc), nitrous maybe, and EMS (MoTeC most prob)

Basically I wanna hit as close to 500 at the wheels as possible.

Doesnt sound like the T67 is man enough. I dont really wanna have to run the turbo at its limit to get my goals.

I might be selling my GT3037s complete kit in favour for the GT3240.

The kit will include:

- Exhaust Manifold
- Downpipe
- External wastegate
- Screamer Pipe

As I said this is only a might be. I need to check my finances after my T78 purchase fell through.

If you want 500 at the wheels I'd be going bigger. GT35R or T78 for me. A 2.2 will spool these quicker than a 2 liter.

Some of these turbo's are more capable of making more HP than the above figures. Feel free to add other turbokits I've forgotten to mention

Keep me informed Dan not in a hurry per say,

Is that what is on your beast at the mo? where does it kick in really? Just want an idea on the lag side of things.

Steve: Cheers for that mate bit too tech for me, some of that!. T78 is way to big for me I think. The lag would pi55 me off whe I wanna get going from a stand still. I know the 2.2 will help it spool up quicker but how much quicer.

Is there any power readouts of a 2.2 with a T78? and a 2.0 with the same? I'd like to see where the turbo stats taking effect.

At the end of the day a quick spooling turbo that will provide 500rwhp+ is like searching for a snowman that wont melt fella.

If we look at Andy's car, he made 408 at the hubs at 1.6 bar. Potentially a little more could be had out of it if it were revved higher and had a fan blowing cool air at his IC. So say it was 420 at the hubs. You'd still be looking at 2 bar for around 500 at the hubs - thats on a GT30R.

If you want to run pump fuel, realistically your looking at a bit bigger turbo again - or atleast a larger AR on the turbine side to flow a bit more air out. Question is, do you want to make 500rwhp at say 1.7 bar at 7500rpm or at 2 bar at 8k rpms. Up to you really.

[stevecordiner]

Oh just noticed you mentioned nitrous being included in the 500rwhp.

I'd probably go with a GT30R with the larger turbine housing. Get you to around 450 at the wheels then use the nitrous to get you over the 500 mark when you want it

[JJ]

I dont see the HKS T04R on that list... or is it too old now !!

Lol ... he said 500 rwhp not 700rwhp

Cheers steve no probs. I often forget Im adding the nitrous too. I start some research then Half way through I remember and I kick myself lol.

Now I've seen the GT3037 which is the one I considered. but there is 2 variations as follows. Option 1, 480 - 500bhp. Option 2, 520 - 550 bhp

You have said GT30R? is that the same thing just a different name?!?

Where would I get a manifold from at a decent price? The HKS one is well expensive!!

Dan: could you confirm which varient you have if possible?

[stevecordiner]

GT30R ball bearing unit - speak to Andy about his I'd suggest.

Manifold - find out what flange fitment is required and then buy a manifold to suit it - then just get a custom downpipe made up. Is yours a rev 1/2 or rev 3?

Full race in the US are making some fantastic manifolds for the 3SGTE now, all robotically welded etc. Even the going price on one of those, although expensive is still a lot less than the HKS one IIRC

Mines a rev 3. So the GT30R is different? to the Garrett GT3037 which is also ball bearing.

Glad your not in a hurry as I need to check my finances first, and also need to find a suitable replacement.

Beleive it or not, a T78 with a 2.2L will produce about 650HP @ 1.5 bar...obviously with 1000CC INJ and a nasty fuel pump and a boot mounted IC IMO

The 3037s has good spool times if your revving at say 4500+....but in 4th at 60mph @ 3500(ish) revs when you plant your foot down there is some lag. Its still driveable though...but only just.

[michael]

A *very* rough guide

[JJ]

Michael,

when we seeing a T-78 fitted to yours ???? cheap as chips !

[ENSMR2]

Good Good me too Does the screamer pipe do just that? MScream? No benefits from it?

I really dont wanna go big a55 turbo. I'll be using mine on the roads not at drag strips.

.

If I was in fourth at 60mph I'd just drop it down Hopefully the stroker kit and having the intercooler in the stock location should give me quicker spool up times any way. And thats what Im after.

By the way I am trying to learn how an external wastegate works. How stuff works site doesnt go into it. Can some one explain with the aid of pics if possible. I'd like to see how it all looks together etc.

[michael]

Michael,

It doesn't really appeal to be honest, if I had unlimited cash I'd go single or for twin 67s but the car is too fast for general use on the roads as it is so I can't really see the point for an odd 1/4 mile event here and there.

*puts slippers back on*

[stevecordiner]

Lol ... and a 2.2 T88 MR2 would make a nice sensible road car for you Mike?

That would be a weekend toy, if I went for an MR2 I'd probably buy something to rattle about in during the week
