Stupinks mr2 turbo WIP thread :) 293hp

[TiM3]

Oil pressure sender is 1/8 BSPT which as men3cac mentions is a taper thread, plenty of adapters out there though.

[TiM3]

This is my oil pressure switch/sender, it is mounted remotely where the carbon canister was and fed by a stainless oil pipe, I wanted it up there as it looked a bit tight and precarious hanging off the front off the engine.



I agree with stupink in terms of oil temp and have tapped straight off the Eliseparts sump, the sender for a Stack gauge was M10 x 1.25, but I guess manufacturers vary.

[stupink]

Lately a fueling/noise/boost issue has appeared,, been a wierd one thats been hard to trace as the symptons have varied each time i tested it.
Found two of the four turbo bolts had fallen out (they are a notorious pain in the bum to fix well due to the temperature and movement).. and also it seems I had a de-cat somewhere along the way lol..

Ebay sports cat was installed..
but it tried to escape..



you can just about see the missing center part wedged further down the exhaust on a bend..  no wonder the car wasnt making boost properly.. oops..

Not sure if the cat was bad, if i've fitted it too far to the turbo (shouldnt matter) or if some of the ignition cuts i had while setting up may have blown the cat apart.. (read.. i maaay have tried launch control briefly a few months ago, and its notorious for killing cats).

[Leethesparky]

Lots of great info here mate...

A good project well done.

What caused the cat to go?... are they rubbish, because I have been looking at these for my project.

[stupink]

I'm fairly sure the cat death was my fault and that it only died after i played around with launch control, which is something you shoudlnt really do with a cat installed. So sadly I can't comment on their quality, and whether or not it would have coped fine with normal/hard use.. I think i would be tempted to buy a decent one if doing it again personally though as we still struggled a bit to get it hot enough for MOT (a problem you'll always have with a sports cat though to be fair)

I use those nuts and since then I forgot that there is some nuts...

[stupink]

Few minor tweeks since, still working on my big brake kit but slow progress as #lazy, and its only really the FAST circuits the std brakes can't cope with, road and small track she is fine, but nothing too exciting until the last few days.. The purchase and install of traction control by racelogic  s:D s:D

After a few too many "iffy" moments in the wet where the back went out fast, unexpected, and I felt I caught it more luck than skill I realised she's just a bit too aggressive for road use and either don't use it or tame it.. This I figured would also equate to a boring session on track in the wet on a circuit that doesn't have enough straights to go full pelt.

So Traction control was needed, I looked at options and by far the "best" seemed to be racelogic, but not produced anymore I had to wait for a second hand unit to come up.

So I took a horrible mess of wires from my Emanage


Added some wires


And ended up with even bigger mess.. yay....


Its quite a funky unit, with PC software to calibrate, basically takes a wheelspeed from each ABS unit, RPM from the ECU, (power and earth) then you cut each injector wire and the unit sits between the gap so it can decide if the injector should fire or not.

Quite a quick setup, just factory reset the device, then selected which wheel was which by spinning up one wheel at a time with the car jacked up, entered the ABS teeth configuration and tyre sizes and tested the RPM signal.
you can setup how much slip you want in wet and dry conditions..  allow more slip in a straight line than cornering for quicker starts, setup launch control for full-boost launches..

Only been out and tested it once, but its a different animal, even in first gear I was able to approach a 90degree bend, go full throttle and just steer round the corner, in the past i'd have been pointing backwards before you could even blink...   lift-off is also safe, so mid corner you can lift and it doesn't snap(because its not slipping much in the first place)..  

I went from a car I often pushed harder than it could deal with, to a car that can deal with more than i'm happy to push.. very happy   s:D s:D    s:bounce: :bounce: s:bounce:

Wish I had this sort of mechanical knowledge, would love to carry out this sort of extensive work one day on a project of my own!

Everything I know is self taught from day one. Trial, error, listening to the right people, asking the right questions and reading the right articles  s:) s:)   also getting it wrong a lot haha..   I started about a month after getting my licence by going to a banger racing meet and thinking I like that, so I bought a cheap car and went and did it the following month  s:) s:)    just get stuck in and you soon pick things up.. don't be afraid of breaking things, just gives you more opportunity to fix stuff and learn even more than you were expecting  s:mrgreen: :mrgreen: s:mrgreen:

[shnazzle]

Just randomly found this thread. Do you want it moving into Reader's Rides?

[stupink]

Sure didn't know we had one. I guess we didn't when I started this  s:) s:)

It's relatively new  s:) s:)  Moved for you.
It's an interesting build so it definitely needs an easily-referencable place

[Anonymous]

Thanks for this topic. Cool and very nice build. Anyway dude i saw you re using an emanage. Would the blue work too? How did you force open loop?

[stupink]

Hi. I setup a referenced fuel pressure regulator. So the fueling sorts itself that way, I've never really looked at how the fuel trims ended up after I stopped tuning. But I can only assume they're not fast enough to keep up as it fuels well  s:) s:)

[stupink]

Just fitted front camber bolts, and also supplied from GT4-Play,
ACT 6puk sprung with extreme pressure plate,
Full polyurethane bush kit,
Roll centre correction balljoints..
And that's the car done  s:) s:)  All finished!! for now! final last words perhaps..

Hey Stu - how do you find the difference in handling with the new polybushes? I also noticed that you've not added any bracing?

[stupink]

The poly bushes in mine had gone soft (they looked okay, they just were soft. or perhaps they came out the factory like that..). so the difference is phenomenal, I also did the roll centre corrector balljoints at the same time, so its a bit hard to say what change of characteristics was due to which mod.. but without a doubt very very good money spent.. I have a "safe offroad test corner" ahem.. and 40-45mph carried speed turned into 45-50...  and it turned at the same time from scary to fun...  back end going out from skippy and hoppy to smooth and controllable..   any doubt.. do it.. unless it will bankrupt you.

The bracing is minimal yeah, I have already got some though, I have a mid plate, and front lower brace..  I'm not sure how much faith I have in the belief that top mounts are beneficial as rear already has one, and front top mounts are soooo close to the bulkhead... but maybe if I trip over one someday outside my garage door I may fit it and try it.. because why not..

[jvanzyl]

hang on... you're saying that you already HAD poly bushes but they were defective?

I got the full polybush kit installed (no idea if this includes the roll center corrector ball joints) and I completely agree with you regarding the "scary to fun" transition. My rears don't spin anymore when pulling away and the grip is just great frankly.

I've got the Matt brace and the UR front strut. I can honestly say that I had a night and day experience with the front strut one... turning in is so much tighter, and the general handling over bumps massively improved.

I think there are few of these braces kicking about on eBay (AndyN20) and I reckon you get one for about £50. I'd recommend it.

[shnazzle]

Front definitely does something. Almost as noticeable as Matts brace.
Rear is an utter waste of metal

TRUE

UNTRUE ish

Sorry I typed it on my lunch break too quickly, I just meant the oem rubber not polyeurethane.  so it was oem 10yr old to new poly... and the ball joints aren't part of any bush kit so you'd not have that, its only relevant if you're lowered... when you lower a car you mess up the control arm angles so the car flops around like a fish out of water even on firm springs.. these correct the angles back to nearer stock. stops a lot of body roll..

[CrazySX]

Hey Stu,

Just read through your whole thread, some very good work here, you seem very much like me, do it yourself and experiment with things lol! i really like the liquid poly idea, how are the engine mounts fairing up?

[stupink]

They're spot on. I upgraded to some 80sure. Bit noisy but definitely Less movement, and I'm keen to stop engine rock much as possible as it leads to manifolds cracking. Definitely recommend doing them.

So the higher the number the harder it sets?

I am thinking about doing my 200sx subframe bushes  s:) s:)  was going to inject them with pu sealant lol!
