just got myself a datsun sunny wagon, two actually. And i am looking at putting the sr20de motor in it i looked at kits and there worth about $800. But im not actually sure what the motors are out of or how much there worth.
Also i plan on doin some performance mods to it firstly i wanna know what wold be better for this motor as a hot street car, a super charger or a turbo?
Any thing i might wanna know about the motor befor i start or whether there is a better choice other than the sr20.

Have a look at datsun 1200 post 2 door it runs a sr20de with a turbo 11.012 qmile not a easy thing to put together not legal for the street in sydney. not sure were you are if its the same laws

I am almost finished a SR20DET conversion in my sunny sedan, the car is still a fair way off being finished but the conversion is nearly done.
Unless you are going to rebuild the motor with stronger internals, I would recomend starting off with a DET motor as they have stronger internals than the DE variant, which for a blown or turboed motor you would want.
A 2 litre turbo motor is legal in Queensland in a sunny but it would pay to check with the authorities down in Vic first.

As for blown or turboed, I would just get a DET motor and upgrade the turbo and do some head work myself, if, as you say you want to do some mods. But you could do some reserch on the blower that Aaron Fitzpatrick has on his SR in his 'FIVETEN' 1600.

Also, expect to pay from $1500 to $3000 for a silvia or 180sx front cut.

FIVETEN has a GT35/40, the procharger wasnt legal (too loud)

My first question is what exactly do you mean by "hot streetcar"

You are the only one that can answer that, What I think is "hot" and you think is "hot" could be completely different things.

I suggest you build a car that you want not what other people think of it.

secondly, before you start any project first determine what you want out of the car. then pick an engine that will suit your application. If you want to turbo the engine, and you have to buy an engine anyway just buy a turboed engine to start with

you will save yourself alot of time and money, converting a NA engine into a turboed engine is alot more difficult than just slapping a snail on the side of it.

The only other advice i can give you from my experience is work out what you want, plan your conversion properly and most importantly start off on the best platform possible. Engine and body wise.

on silvia web site a sr20de normaly sells for $200 and are ezy to put a turbo on as all the standard stuff is cheap but you can only go about 7psi anymore and you need too do the motor .... expect tooo pay $500 for a gearbox tho as the turbo boys blow em and all ways wanna buy em ... how much power do you want ??

well i wanna be able to beet a commodor xr6/8, something that will put a smile on my face every time i drive it. iv got about 4500 to play wit. With getting the de its that im only on my l's and wont be able to drive it with a turbo under new laws. is it possible to put a super charger on in stead of the turbo get the det and put a super charger on it?
is 250hp a bit ambitious?

um looking at the prcie of front cuts i cant find one under $2500. I only need gear box and a fully dressed motor im not really after the half cut.

Firstly, the reason you buy a front cut is so you get a fully dressed motor with everything you need for a conversion.You will not save money trying to do it another way unless you buy an engine/gearbox combo from someone who is doing a complete engine conversion into their silvia or 180. After you buy all the little bits and pieces( if you can find them) That you didn't realise you needed , it wont end up any cheaper, just more of a headache. There is demand for the leftover bits and pieces of a front cut that you can sell to get some money back.
Secondly, if you are still on your L's, why not do yourself a favour and stick with an a15 with a bit of work to start with. An sr20 manual in a sunny, will , IMO, be dangerous for a person who hasn't much driving experience, and other road users, Much the same as a v8 commodore or falcon.
But thats just my 2 cents, take it or leave it...

The sunny already has a mild a15. And i have alot of experiance in a car (rally). And im sure i could handle a stock 2 litre. After looking at the price of the motor i am looking at something cheaper fj20? or ca18det? 4agze?
