please help

[oiyshi]

i was wondering if anyone knows in detail in how to swap a sr20det engine. or if anyone knows where i can obtain this information, im planning on learning. but i dont know from whhere..please help!~

[Cavi Mike]

It would prolly help if you told us what car you were putting it in.

[American Psycho]

My guess the typical 240

[aznflick]

you could put a sr20det into a sentra but thats the pulsar sr20det

[nismoron]

The pulsar SR in a sentra is a difficult swap. The bluebird SR drops right in though, and is a much more common swap!

[nismoron]

Oh and to answere the original question...
Yes... have done several 180 SR's in 240s and Skyline RB's in 240's
as well as bluebird and Pulsar SR's in sentras.

[aznflick]

well that something new to me i thought bluebirds were RB'ed.

[nismoron]

Bluebirds (late 80's?-90's) were SR20DET FWD except the SSS which was SR20DET AWD. They probably had some SR20DE's and CA18 models as well but no RB's that I have ever seen. It is the same car as an Altima over here. RB engine is too long to fit under the hood. Some of the older blubirds maybe... dunno I know the early 70's bluebirds had L series 6 cylinders like the 240-280Z and Skylines.

its for a 240sx (old style, 180sx), i wanna start from scratch. just the body and then popping in an eingine, but i want to learn. try studing up on it.. i want to do this for the experience. someone please help.

help what? What are you wanting to know?

[nismoron]

Is it a 89-90 or a 91-94. What year SR are you wanting to pu in it. The wire looms are different. Easiest swaps are:
89-90 S13 = CA18DET
91-94 S13 = SR redtop or RB20DET
95-98 S14 = SR blacktop from S14 or RB25DET
Blacktop from S15 will have a different wiring architecture and require more mods to the wiring harness. I am not saying that all of these motors will not fit in the other cars listed. I am just saying that the wire harnesses will be more similar and easier to get running.

Also when buying an SR you need to decide which model to buy:
Redtop had best flowing head and is best if high HP mods are planned.
S14 Blacktop has better stock turbo and less head flow. If turbo is going to be upgraded get a redtop, if left alone get a blacktop. S15 blacktop has better turbo as well and better internals but still has lower flow head and will probably come with a 6-speed . Sounds like a great thing, but
think about it... extra gear in same size case=weaker rears. They have reliability problems if you get above 300-350hp. Thats why many of the Japanese D1 cars have 5-speeds and/or upgraded tranny internals.

What are you building this car for? How old are you? And what kind of money do you plan to spend on the build and on maintaining the engine/car? Who will service the car? Where will you get parts? These are VERY important questions you have to answer before you can do an engine conversion. An SR may be the cool thing to own but not the best option. There are more economical optionsa as well as more powerful options!

i want to know if there is some book that i can read or something that will help get me started. anything that will help...anything that has to do with this subject

this whole purpose of me wanting to do this is to gain experince, have a little taste of what it would be like. im 18 years old and i dont know much about engine swapping.. i know the basics of how a car works and stuff.. but i would like to get deep into the understanding of cars...starting from here. i plan on spending no more than 5-6k on this project. im not worried about getting the parts cuz i know plenty of hook ups, i also have a frined that has all the parts and tools that i need to get the job done... recommendations would be fine on where to start, what kind of enigne i should get.. im still a beginner to all this.. thank you

download the 200sx manual and study the basic of the sr20det.

You can get it on Zilvia.net or dot com, cant remember which it is.

What are you going to use the car for? Street? Drag? Drift? Circuit? Autocross?

Dont say a little of all... They require totally different setups..
Drag= soft rear suspension to squat, higher weight center for transfer, and higher RPM power band.
Drift=tight (almost none) suspension, lower weight center, and broad torquey powerband.

A car can be made good for one thing but it will only be mediocre at others. It can be made mediocre in all but it will be good at none of them.

I have a 240 with RB20DET setup for drag, but with a drift suspension. The suspension is too hard and drag launches like crap! And the heavy engine throws the weight balance off a little for drift... Makes a decent street car, but not competitive in any of the other areas.
