Sr20det Or 1g-gte?

[Tiger]

That's what I discovered to... and that BLCJET Supra in VIC really impressed me with his dyno figures! They are a damn tough motor.

[ancullen]

oke020? SuperJamieJr??? And both of you seem to have the same colour cars...

 

But back on topic, I would have thought that the only advantages the 1G-GTE would have over the SR20DET would be:

• It is a Toyota. A Toyota powered by a Toyota engine is nice.
  
• It is a six cylinder motor. In this case that doesn't mean more power, but it has coolness factor.
  
• You can use a W-series Toyota transmission, which is a gearbox that has been used previously in KE55's.
  
• A 1G-GTE is cheaper to purchase than an SR20DET
  

There are probably more benefits, but I can't think of them. The SR20DET benefits I can think of are:

• It's an SR20. They're renowned as a wicked motor.
  
• More power can be made than with a 1G-GTE
  
• You're going to have to change so much drivetrain anyway that you may as well go the SR20.
  
• An SR20 is cheaper to upgrade and improve than a 1G-GTE.
  
• The SR20 is (I think) lighter than the 1G-GTE (all alloy SR20 versus cast block 1G-GTE)
  

So as much as it pains me to say this, I think the SR20 would be the best option for outright power and lightness. If you just want cool factor, go the 1G-GTE as they're not used in very many conversions.

That's a pretty smart post there, ancullen. Once again more to think about...

 

Damn! When this thread become 7 pages long??? Oh well... this has become a very informative and mind stimulating thread, I must say!

Umm, I don't think W boxes ever came in KE55's.

[ancullen]

I never said they did, all I meant was that people have done conversions into KE55's where they use a W55 (eg. 4AGE with W55 and appropriate bellhousing). So it does fit into the car (with some minor bashing of the floorpan).

what sort of fuel efficiency did you get out of the 12a, scott? was it efi or stock 4 bbl or a weber?

[1G-GTE KE70]

CA18

[oke020]

Jamie, was running the standard nikki 4 bbl, pretty good fuel economy actually, dependent on your right foot though, i had the usual conversion to mechanical secondaries so as soon as you buried the foot to much it started to chew.

 

Had a play with a 5 series BMW one night on the highway, the driver stuck his nose up and tried to accelerate away from me, to cut a long story short i ended up in 5th at 8500 still sitting next to him while me and my mate where in fits of laughter :P i don't know what speed that equates to but at this stage the car was still 12a, had 155x12" tyres, standard suspension and standard brakes so it felt like warp factor 5 :D

5th at 8500 :P ? Nice one! That must have been a V8 5 Series then. Because if you're able to get up to that sort of rpm in 5th (not accounting for really short gearing) then you'd have to be doing some pretty serious speed. 200kph+???

[Super Jamie]

yeah i've heard rotors matter alot how you drive them. ah well, time to find out for myself. next engine is 12a :P

 

easily over 200km/h. more like about 225km/h! that's a fast corolla!!! :D

[Teddy]

WWWWeeee I'm a "(replace fish) FAST COROLLA!!!!

[ancullen]

Mmm, a rotor powered car would be nice one day, but first I want to do a wild 4A-GZE (current engine), a screaming 11,000rpm 4A-GE, and a 9,000+rpm 3S-GE amongst other things. Then I might get to a rotor, but I'm in no rush.

[Super Jamie]

i am in a rush for a rotary. my next engine must have 0 pistons :)

[ancullen]

I'll take your KE25 off your hands to clear garage space if you'd like. I won't even charge you anything. :)

[ancullen]

Which reminds me of another project I'd like to do: KE25 with hard tuned 2T-G or 3T-G. Not EFI, not turbo. Just a pair of dirty great Webers hanging off it. Mmm, Webers...
