Which car is the 22R in?

bore out the 21RC block to take the 22RE running gear... nobody will ever know Just tell em you stuck the EFI head on

1g FTW!

If it has to be a 4 I'd prolly go with a 4age or 3s.

[o_man_ra23]

4AGE is too small and not torquey enough to lug around the RA60. Dad's Mr2 struggles with torque and is hard to take off.

Cheers, Owen

bah i reckon a 22re would be the 4age due to similar power and an extra 50Nm of torque. Small port might be close even then I'd put my money on the 22re. 3sge however would be nice.

[Starfire]

Depends if you are talking in stock form or not.

The RA6X isnt that heavy is it?

Depending on the class rules a beams 3s is probably the best engine choice but they arent cheap. A restrictor may kill any advantage the engine has though.

For a rally engine with a restrictor it is best to determine the maximum flow supported by the restrictor and then build the engine to make as much torque as possible from that flow...

[mullett]

Yeah, it has to be NA. Hence no 1GGTE. Apart from that, I don't think there are any restrictors. I think you need to stay with the original number of cylinders though. What's a BEAMS 3S worth, compared to a 20v? I'm guessing I'll have to source it over east and bring it over. By the way, factory weight is about 1050kg I think.

The 1g also comes in NA form and with a little bit of work can be quite amusing. It sounds like you are stuck with the original number of cyl though so it looks like the 1g is out.

The beams 3s is worth something like $3500-4500. For that much you usually find them with the 6 speed still attached.

A 20v silver top can be purchased for $1100 or so if you look around carefully.

Certainly a big difference in price. The 20v will be an easier conversion especially if you can find the crossmeber from an AA6X

[RONA]

I'd seriously look at something like a 3sge not necessarily beams over the 20v, I know its not a toyota enigne but for price wise even a SR20DE out of a S13 would be good package, cheap, already RWD. not to mention a plethora of parts ie cams, pistons etc. Sure theres plenty of 3sge parts around but the SR20 parts will be cheaper.

[mullett]

Yeah, it's always a consideration, I'd like to stick with a toyotamota, but it's not imperative. Whats a 3S and a RWD box worth? I imagine they're in demand for the sprinters. Also, does anyone know where that list of engine suppliers was on the forum? I searched but couldn't find it.

Not a lot of sprinter guys go for the 3s - they are actually a pretty heavy engine for thier size. In fact an iron blocked 3s weighs slightly more than a 1UZFE.

The important thing with a sprinter of course is weight distribution. In your case I think the extra power and additional weight of the original car would offset that somewhat.

[Norbie]

A 3S is lighter than the original R series lump so it's definitely a step in the right direction!

Note that 3S RWD conversions aren't exactly cheap or straightforward, and the only factory RWD 3S is the BEAMS version which is also quite expensive. I hate to say it but if you need to use a RWD 2 litre 4 cylinder, the SR20DE is the best bang for your buck.

The 1G-GE is another good option if you're allowed to run a six, so grab a copy of the rules and see what they say!

[Starfire]

I would love to build a crazy NA 1g

6 throttle bodies, big cams, extractors and a ported head.

*drools*

[mullett]

Hmmm. I'll have to find out. How much power does an NA 1G make? On the bright side, it'd be an easy as conversion...
