Stupinks mr2 turbo WIP thread :) 293hp

[lamcote]

Thanks for all the replies, really interesting.
One more question I have is, based on Stupink's last comment about the standard ECU.
Is it possible to run a turbo installation with the standard ECU only? If so is there a maximum power that it can handle? I was expecting that any turbo would need at least a piggy back ECU if not a standalone option.
Thanks guys, sorry if I'm asking daft questions!

[stupink]

I'm not sure anyone does it. But if you were able to sort the fueling with an ajustable pressure reg. I get the feeling the std ECU will sort ignition for low boost as long as it was not too hot I take temps. Mass air flow meters really do create a bit of flexibility. But I would imagine the boost you could run would be fairly limiting. Go piggyback or full ECU.

Did the TTE turbo kit do without a piggy back ecu?

[tomaky]

God i want a turbo! Hmm might start picking bits up over the next year.

I don't know how you non turbo guys do it.  I suppose we give you something to aspire too though.

Less weight, some suspension and brake tweeks and a well driven na car would keep up with a turbo car in track, been there, done that  s:D s:D

Ain't it the truth  s:!: :!: s:!:

[tomaky]

I keep up very nicely in the twisties with a Turbo friend of mine  s;) s;)

No the TTET came with a piggy back. It was very much a sealed unit though and you couldn't really mess with it

Let's reduce the power of our engines so we can be faster around the track.....

Are you on an intercooler or a charge cooler stu? I'm shopping for a charge cooler at the minute but the one I won on ebay (twice) didn't meet reserve! Same with the cars, I've won one mr2 3 times now! Lol.

[stupink]

Chare cooler. Its pictured in the posts. IMO there's no good place on these cars for a decent sized intercooler. Its either too small, too much pipework, or in the flow of hot air from the engine

Random little update.

My second engine is now stripped and down the shop for a rebore, saving to buy a rebuilt "kit" for it and will then get it all together and swap it in to reduce my oil consumption which is currently about 300ml per 2-400miles.. not silly, but kinda annoying. (i only drive the car rarely and 50miles at a time so this equates to once a month)

Current engine now has a uprated actuator rather than boost control via the ecu on a lighter actuator, just trying to get it to hold boost better high rpm without faffing around mapping it (hard when i can't map and drive).  so now holds 12psi solid rather than dropping to 10/11..

Fueling is still a little lean, the injectors are actually maxing out duty cycle about 5,500rpm(but just scraping an acceptable AFR), so i've got some 470cc to go in, which should be sufficient even if i need to turn the fuel pressure up a little.

I've got my AD08R tyres on now, eeeepic!!! I can now drive the car even in the rain, ok first and second will light up, but in a very controllable manner thats not too dodgy, back kinda stays inline just spins up a bit.

beyond that i've just been driving it  s:D s:D    

oh and i may have accidentally put an actuator on too strong and been out for a blatt with 20psi hahahah SOOO much fun, but would never last so that got sorted after the car cooled down! haha.

[stupink]

Inectors arrived last night, so today I have fitted them..  I did a bit of research and came up with 470cc Astra VXR injectors for £80 deliered (second hand), they come up ALLLL the time for that sort of price, are near as damnit a direct fit replacement for my white giants (already got the loom modified for them).

Essentially the top had a bit too much plastic for the retaining clip on the VXR, so I' trimmed them down.. all in place and running nicely now  s:) s:)   Great price for a set of bosch injectors, and worthwhile considering anyone who's upgrading, a good flow size and a good genuine bosch injector for the price  s:) s:)

Just trimmed with a stanley blade, not difficult the plastic is quite soft.

Searching sandwich plates...which did you use? Do you recommend?

Fitting oil temp and oil pressure gauge

Thanks

[stupink]

I can't be much help i'm afraid, I just used the one on the car when i bought it. but I fitted my temp gauge into the sump to get sump temp.  the sandwich is just a cheap one as I havn't got a cooler other than OEM, so don't need thermostat. so litterally any will do if the right size if its just for oil feed for turbo and pressure  s:) s:)    if its pressure only you could just make a T piece and use the OEM port above the filter and not even have a sammich  s:) s:)

[Anonymous]

Thanks, I want to fit oil temp and pressure gauge, so will have two sensors. Do you think it's best to go with a sandwich for both sensors?

Not interested in drilling my sump though!  s:( s:(

[stupink]

I don't see the point in having oil temp anywhere but your sump.   rephrase, I would rather not have oil temp anywhere but the sump. because otherwise you're just measuring how much temp is being held in the block, or that the oil pump is adding etc.. not how effective your oil cooling is... do you have a standard sump then i take it,  what you're looking to do then is find or fabricate a oil drain plug that has a centre core to take a temp sensor. then no modifications to your sump are required, and you'd just ahve to disconnect the wires before unscrewing the sump plug, small extra hasstle when doing oil changes.  then you can just run a T piece for the two sensors pressure wise. no sammich needed

[Anonymous]

That's interesting thanks for letting me know.


I'll look into it.

I am planning on getting a baffled sump in the future so can use that but I won't be for a while.

Is there an easy and convenient place to t-off for the pressure point on the mr2?

[stupink]

Just unscrew the oem pressure switch, then put a block adapter in and scew both sensors into that  s:) s:)

[Anonymous]

That sounds sensible, thanks for the information  s:) s:)

[Anonymous]

Don't suppose you know the thread for the sump plug; is it m12 x 1.25 (fine)?

Also same question for the pressure adaptor

Thanks for all your help!

[Anonymous]

Be careful with the pressure as I think its an odd tread.

Oil switches or senders are often a tapered pipe thread of some description
