An SW20 RALLY car?!?! As in an SW20 on DIRT?!

If so, I'd say the driver probably has more amazing skills than some sort of power advantage over the 4WD cars!

Why is this so hard to believe?

MR cars used to rule the rallies. Lancia stratos anyone?

However, they eventually got superceded by the 4wds.

There was also a porsche rear engined rally car too! It did okay, but porsche just werent even interested in it.

I have this great rally car DVD *coughDIVX*, with all of the classic rally cars on it.

[Adamal]

Ahh yes, the Stratos...

But as you say, the MR's were superceeded by the 4WD's, and this SW20 was aparently leaving the 4WD's for dead!!! THATS what amazes me!

Wouldn't mind checking out that DVD *COUGHDivX* too

i'd have to agree SW20 on dirt is nuts SW20 in wet is somtimes crazy enough

Mine is a hell of alot easier on gravel/dirt than it is on wet tarmac. You actually get warning of when its about to break loose.

Yup, they seem to really dig in when you boot it in gravel...only had mine on gravel once, and it was a blast

[Gx71man]

well its not the money that is worrying me. i already have a s-afc that i was going to run on the mr2. the Sc14 i can afford. custom bracket and pipe fabbing i can have done for free. Also it's different. i dont want a turbo car, i know they are fast but theres so many and they are so common now. so yeh, anyone know of a 3sge for sale?

I may no of one dwn here in palmy nrth, i will ask the dude that owns it. is in a sw20 mr2, who noes you may get the hole car for a good price. Im not promising nufing but i might be able to get you it.

Oh its in a car with no roof, motor should be good, but im not to sure.
If i rember i will ask the dude that owns it.

wow thats amazing better on dirt then on we trammac? i had my celica on the dirt going 100km and it does not feel safe at all

[thaphatty]

my ae101 felt like a magic carpet on gravel (driver not gravel experience+car bog standard)

dunno if this is the mr2 your all talking about but maybe?

[Zero_Cool]

that looks mean

[Liloss]

well here i am again with this stupid idea of mine. firstly does it really matter what side the SC is mounted on? what size injectors should i run?

cheers

[Adamal]

You've gotta mount it in a place where its not gonna be in the way. Then you need piping going to the intercooler, then to the intake. You need to mount it so that you can get a belt running to it. Thats the trickey thing.
As for what injectors you will use, I'd say that if you're going to be using a roots type, you'd probably be able to stick with the N/A ones, as roots type provides power down low, but will be maxed out up top. As you're not going to be reaching your peak power down low, you're not going to max out your injectors. To play it safe, I'd buy some second hand turbo ones.

[Malcolm]

if you really want to do this then I'd definitely recommend starting with a 3sgte. Can sell the turbo and associated bits for a few hundred $$ to help offset the cost. Then it will have no problems dealing with the boost created by the supercharger.

[CozmoNz]

i drive the misses mr2 on gravel all the time, and the last few weeks, on ice...

goes aiight, you just need to hold throttle and learn to countersteer continioiusly...

she slips out slowly, and right when you expect her to, no snapping .

i think theyd make great wee rally cars... but then again, traction is faster than sliding... so a 4wd will always be quicker :S one way or another.

[Liloss]

nah dont need to buy a 3sgte, seen a few st183's running a SC without probs. The trend seems to be to mount the SC14 where the AC was on the st183, ok you gota remove the AC but who cares, its only excess weight when you have windows and a sunroof

[ee904age]

It has already been done by a guy in Wanganui. Don't know if he went with the 12 or 14 though. Fitted it all to his SW20 rally car and embarrassed a hell of a lot of 4WD cars. Would have been about 4 years ago that I saw it.

That would be Paul Tulloch, he owns Wanganui Exhaust Centre. I dont know much about the car except it goes like a cut cat and sounds like a jet engine.

He's a good guy, easy to talk to, I'd say give him a call if your thinking of doing it. 06 3453228

That'd be running about 6psi or less. You wouldn't want to run anymore than that on 3SGE standard internals. Remember, they're not made to withstand the ammounts of pressure that boost adds.
I'd take All_Four's word for it. I've seen some of his work.

[Mr Revhead]

but thats what a lot of ppl say about the 4age... and that can handle heaps more.... thay also share conrods and crank, just like the 4age, so id say they can handle quite a bit mote than 6psi.
its all in the tune

so id say a sc14 would be fine with a good water to air intercooler

[Adamal]

But are the standard pistons up to it? And how can they share the same crank and codrods? That would mean they have the same stroke and that the 3SGE has a bigger bore. And if the crank were the same, then the conrods would go in the same place, meaning that the centre of the pistons would also be in the same place. The 3SGE would essentially be a bored out 4AGE, and 400cc is a lot to bore out!!

[Mr Revhead]

i mean the 3sge and 3sgte share crank and rods just like the 4age and 4agze ya n00b

[Gx71man]

hehehe.

[Malcolm]

well here's my reasoning for why I think the 3sgte would be a better starting platform:
1 - a 2nd gen 3sge is map sensored. If you want to run positive manifold pressure (aka boost), you will have to fool the ECU somehow, otherwise it will go into limp mode around 1psi.
2- a 3sgte ecu has mapping to retard timing as boost levels increase, helping to prevent detonation. You can get the same result crudely on a 3sge by retarding the base timing. Easy, but it also has the effect of making the car sluggish off boost, aswell as degrading fuel economy
3 - the compression ratio of a 3sgte is better suited to a boosted set up, so in hot weather you are a lot less likely to get detonation
4 - a (gen 1 & 2) 3sgte has the advantage of having a fuel system that will easily supply a 300hp motor
5 - cam profiles and timing are also designed to suit a boosted set up. Wont go anymore into that aspect because I'm not sure on the exact differences, or the theory behind why they're different.
6 - already has an intercooler, if you mount the SC in the AC compressor position it will be very easy to plumb up to the stock top mount

but at the end of the day it's up to you, those are my reasons for why I would do it that way, but I understand many people would prefer to go for what is percieved to be the cheaper option, a 3sge is probably going to set you back atleast $700 less than a 3sgte, and most wont see past that fact when considering the cost of the project
