Mike's ST205 GT4 build thread, update: tuned to 200kw Options

[delusionz]

They both drive very similarly around Auckland. The SS-III is a little bit more nimble, steering and clutch isn't as heavy and you can definitely feel it has less weight, the 3S-GE is no slouch either and being the SS-III with Superstrut Suspension and front LSD the steering is just as responsive and the traction is almost as good as the GT4.

The similarities end when you get out into the country, the GT4 does turn into an entirely different beast. I've seen V8 Holdens in my rear view mirror almost wipe out trying to keep up with me in the twisties meanwhile the GT4 is just going about its business like its no problem.

Overall the SS-III is impressive, but anything the SS-III can do the GT4 eats it for breakfast lol.

Bit excited about whats coming next, so I prepared a sneak preview

[Rusty]

$40 what a great buy how much did that guy want for just the blocks? lol


have you got it yet?

gosh the NZ'ers have been busy this week

[delusionz]

Spoiler showed up this morning

The middle hole here lines up to the rear nut in the spoiler, and perfect on the other side too

I decided to sand off the middle studs on the bottom of the wrc extenders to save drilling extra holes and I bolted it down, it all lines up perfectly.

Now the plan is to use the rest of the guide from 97lestyousay (cheers for that, good writeup.) In the mean time heres what it looks like...

Dude it looks awesome.

I wonder if you can get it rebadged?!?

Alternatively, you could replace the engine driveline

[delusionz]

Spoiler debadged, cleaned and mounted. Drilling was relatively straight forward, now just needs to be painted.

Looks good. We did the same thing on my wife's 96 ST. Instead of drilling new holes to match the blocks standard slots. We bolted the wing down with 4 dry wall screws each side. We tried to bondo the old holes and the middle one but after a few weeks the bondo was starting to sink in where the middle hole is and the two side ones.

Use "GT four" sticker on raiser block will better look..............

[Rusty]

Yeah thats what he's planning to do check 2nd post at the top of the page again


you sure it'll be secure? with just 2 bolts? I'd hate for it to fly off on you.

[delusionz]

I drilled it, theres 4 bolts in there now. -- I just fit it on with 2 bolts yesterday just to take photos and see what it looks like, Didn't drive it though.

2 stock holes fit, so left unmodified, then I used that as a guide to drilling the other 2 holes by lining up a headless bolt onto the paint to make a little dot marking where to drill. It came out pretty good, then I had to make a 12mm hole underneath it so that the 10mm socket fits aswell as the washer.

Haven't been on a high speed run yet, But even at low speeds the car feels totally different.

Its a little bit rattly on the boot at the moment as I haven't yet ordered new protector pads, the old ones are compressed and ripped. Will get these along with the GT-Four badges when I go to Toyota next.

I need to get it painted white, I'm pondering leaving the riser blocks silver?

Yeah, my riser-blocks are a little faded, so I'm also wondering whether to get them painted black or stay with red.

To be honest, I think it will look good either way (your car and mine)

[delusionz]

Been a while since the last update,

Haven't yet painted the spoiler, but installed an ST202 Toms magic lip (already super white), It looks a bit funny being for a 96 st202 bumper, but matches the lines of the sideskirts, Will get photo soon.
(Actually considering hacking it up and turning it into Toms splitters lol)

Car is encountering problem after problem, My superstruts are worn and making noise while cornering and my front shocks are busted + a few minor issues.

And it randomly smokes like a chimney People reckon it's my turbo seals but there is no sign of fresh oil in my intercooler and compressor outlet, and sometimes resetting the immobiliser or punching the throttle fixes it. Neither my oil nor my coolant are mixed either...

[Rusty]

nice grab on the tom's lip


stink maybe: valve steam seals, PCV valve, piston rings??

[delusionz]

On idle it sometimes smokes white/grey and sometimes punching the throttle or resetting immobiliser fixes it, It happens most frequently when I haven't been filling up at the same station with the same gas. (Could be a co-incidence)

When I boost hard it dumps out big black clouds.

And a sniff of the idle exhaust has alot more of an oil scent than a petrol scent...



Suspension getting fixed today, New monroe monoflex inserts in the front and a superstrut ball joint repaired

My MR2 Turbo does exactly what you just said, well about boosting hard. I think this is probably because I have an exhaust manifold leak, as I am missing a stud. Does it make like a chirpy sound at start up and some what continue until it either warms up or doesn't go away? I think it might be an exhaust leak, although I do not know much about boost, as I have just gotten this car as my first turbo car, I suppose any leak, whether intake or exhaust can possibly cause that and be addressed as a boost leak. Then again, I dunno. But listen for that chirpy sound in your bay when idle.

[delusionz]

I have a few sounds, the chirpy one u speak of may be the similar to a sound I would describe as a chugging sound on idle.

The chugging sound comes from the turbocharger area, not sure what it is, but I've checked for shaft play and have none.

Theres also a ringing noise on feather throttle or deceleration right on 3000 rpm, sometimes audible in 1st gear, it just happens on the 3k mark, nowhere else.

I do know from what I can see underneath the car that there is a nice dent in the exhaust shielding just after the downpipe and one of the clips that holds it in is loose. - Do you think this would be the main culprit?

That's a loose or missing exhaust stud my friend. I have that same problem not only in my MR2 Turbo, but in my Celica as well, as one of the exhaust studs is loose and for some reason I cannot tighten it back to sit for the life of me. Mine on the Celica happens in 4th gear, but it is more like the ringing noise and the stud is loose but still sits in it's position, just amazes me how it doesn't fall out, but I think the shield is keeping it in place. Even though it has that, it doesn't make the chirpy sound of an exhaust leak, but the stud is loose. So you might want to check that out. I am not sure what a chugging sound might indicate, but if you (probably sure you have already did this) can, locate where it is coming from. Maybe an intake leak through your intercooler piping? I dunno.

[delusionz]

Cool, thanks for that, I'll check it out.

So the exhaust smoke has nothing to do with the missing stud between the down pipe and the mid section, but is probably the cause of the ringing sound?

This may even be the reason why my turbo runs at 18psi on the stock wastegate??

My car doesn't sound like a chainsaw though...

Well let me see if we can nail this together. Does your car let out a lot or a cloud of smoke during start up until it warms up? I dunno what my MR2 Turbo has exactly, I just know it is on 15psi, it has a down pipe, only the primary cat, and an intercooler. But when I started to car today (and when I have before) it lets out a HUGE cloud of smoke and will continue to do so until it warms up completely and after I have rev'd it a bit. Then it is solid. Then again, it could probably use spark plugs, it has an exhaust leak, possible boost leak, and I dunno when last it had it's oil changed, but looks like it was sitting around for awhile, so I need to do that as well. But I can't really drive it around too much other than the neighborhood, since I still need to fully transfer it in my name and get insurance on it. So I have just started it up and drove it around here.

Anyways, all that is not relevant to this topic except the first few sentences. I just need to get some jack stands when I get some more money and a good jack and I can check it out.
