you can do it but why would you? stick a RB in it instead, you can buy all the stuff off the shelf to do it.

or if your dead set on a 4 cyl stick a FJ in it, they are heaps cooler than the SR's

worst thing you could ever do!!! They have the worst designed heads in the NIssan stable and require alot of work and alot of turbo to make any power. Sure they will make 350-400rwkw, but the drivability is thrown way out the window when you reach these levels.

Do youself a favour and sell the SR to s drifter who has blown the head and buy yourslef an RB. Once again dont waste your time with an RB20, go for only an RB25 or RB26. Both make an abundance of of torque and will stay together for ages. It has also been said that the conversion kits are ready available and can be bought across the counter. The RB25 with typical bolt ons will be capable of 160ish rwkw and the RB26 around 400rwkw. Definitely my pick of engine conversions!!!

I want to put and SR20DET into a gemi coupe for the missus.

her friends (yes its a chicks car) 200SX is pushing 200kw at the wheels with bolt ons, and goes pretty good too

but not for a 6cylinder torry.

^^ thats the best option in my eyes too! haha.

I cant understand why people are shouting down the SR20DET, its one of the best bang for buck 4cyl turbos out there IMO.

Someone i know has a stock standard mechanically SR in a MK I Cortina (would weigh the same as the torrie) just a custom tune and some boost. It is as responsive as all get out, and does a 13.00 @ 109mph, with alot of wheel spin . Its a bloody weapon ans it only has 150 rwkw as it has the standard S13 turbo.

Chuck on an S15 GT28 turbo, bigger injectors, fuel pump, and air flow meter and you can get 220~240 rwkw. You should be able to sneak in an 11 sec pass with that much grunt....

The SR20 has an alloy block, so it is waaay lighter than any RB, meaning the car will have better weight distribution and need less power to move it.

Seriously its a great engine, and you can pick up complete S13 Silvias and 180SX's for about 5K these days, so youve got g/box wiring loom, the lot. Just sell the leftover parts back to a Jap wrecker or drift guys....

its funny that a lot of 180sx guys sticking RB's in their cars.

like i said, if you want a nissan 4 cylinder you need to use THE nissan 4 cyl which is the FJ

You blokes know too much about rice IMHO

You blokes know too much about rice IMHO

LOL, yeah i guess so......

I like a lot of different cars, imports, old school... sometimes its good to have something a little different.

Don't get me wrong though, i'd love to have a high comp, solid cammed, multiple carbied 6 or V8.... but in the end i like to go fast. And bang for buck i can get more for my cash with those other engines

Back to the the original posters question, i just remembered a dvd i've seen, Serious Performance 6, theres a green LJ GTR with an SR20 conversion. So it can be done but i cant remember what was involved or the name of the mob that did it for him. Might pay to look into it.

Hope that helps....

Because of its head!!! they are an inferior design and that is why they are crap lol The RB has a far superior design and will handle alot more revs than any junker SR.

$5000 for an SR!!! You would be crazy to spend that on an SR when you can get RB26's with loom and box for $6k!!! or hows about a 2JZGTE front cut for $3k!!! When you look at it that way the SR suddenly becomes massively over priced doesnt it!!

If you've never done an engine conversion before, I would suggest you just put a different Holden motor in it, because all of the parts can be found at the wrecker's pretty much. You don't need engineers certificates, expensive aftermarket components, complicated exhausts or any kind of 'thought'.

There is no huge mechanical difference between an L4 LH/LX/UC and an L6 or V8 version. There are loads of threads about converting sixes into eights and fours into sixes. I wouldn't bother keeping it four cylinder unless you have a particular reason. The only reason the idea of converting a 4cyl Torana into a hotter 4cyl Torana is because of the HB and four cylinder LC/LJ/TA which have a shorter nose which doesn't fit an in-line six in it.

I could argue til the cows come home about the shit that was being discussed in this thread earlier haha
