Last one I did cost me about 2 and a half grand in bit's and peices (that's minus engine/gearbox), and I did everything myself except for the tailshaft($350).

standard sr gearbox is a tight fit in a E7(some cutting reqired), RB20 box with SR front casing works a treat.

 

Hardest bit is wiring and setting up EFI(new lines, pumps surge tanks etc).

If you're pretty handy you should get away with 4-5 grand, if you need someone to do it for you, budget on 10 grand.

4A-GE is easier from a fitting point of view. ae71 gear allows it to bolt in, but you have to source a t-50 gearbox, and convert the 4a to rwd(unless you want to spend stupid amounts of money on a ae86 half-cut)

 

even a N/A SR20 is between 108-120 kw depending on model, more than most 4A-GE's and the extra torque is unbelievable. the only down side is weight, the SR is only an extra 20-30kg but in a light car like a E7 all over the front axle, you can feel the weight.

can't really say which it better, they both have there pros & cons, My pick would be the nissan though.

What goes harder? SR20DET hands down, you'll be struggling with a 4A-GZ(/T)E to get that sort of power and the SR's have more aftermarket support so it's easier/cheaper to get more power out of.

 

1zj is a stupid idea for a street car, dragcar, skidcar maybe but not street. It's only legal in some states in panelvans only.

Silvertop 4A-GE + T50: 155kg

SR20DE + FS5W71C: 183kg

Difference: 28kg

 

T50: 29kg

FS5W71C: 44kg

Difference: 15kg

 

So of the 28kg difference 15kg is in the gearbox behind the firewall the remaining 13kg I suspect is actually low in the engine with the forged full counter crank (16kg alone! 4AG is ~11kg so theres 5kg) and the crank girdle (don't have a spare one to weigh :P). Probably a little bit in the flywheel too, they're fairly large and hefty but behind the front axle.

 

I don't think you will notice, you'll be too busy enjoying the awesomeness. Then again, I am biased :D

the weight isn't bad, and sitting low helps, maybe not as much in a SR20DE but a SR20DET you can notice the difference between that and a 4A-GE. My pick is still definitely with the Nissan.

 

Thanks for the weights too champ. they should come in handy.

heres what I think a silvertop package weighs

 

a bare 20v weighs 88kg, I know this as a fact, from there heres my eductated guesses:

 

intake: 5kg

exhaust off head: 5kg (extractors)

brackets on engine: 3kg

alternator: 3kg

water pump bits: 0.5kg all up

 

so thats a 104.5kg

 

now the T50 is 30.5kg without a shifter and dry

so 32.5kg ready to run

 

and the starter motor and flywheel

3kg+8kg=11

 

so all up 104.5+32.5+11= 149kg

 

now Irokin this "SR20DE + FS5W71C: 183kg" where is that from? without a turbo I assume?
