... if you think that you have seen problems in turbo threads then multiply that by 100 and that's what you'll get with your sr20 swap. Anytime you heavily modify a car you will have problems that will need to be worked out, but I think that a turbo F20 is better than any SR20 I have seen. What can a stock SR20 handle power-wise? 300whp? If you need to build the motor, then why not sleeve and build an F20? Atleast you know it will fit.

 

Regardless, it is not an easy mod to add a turbo to the S.

The ecu isn't boost friendly and needs to have a piggyback system or be completely replaced and the high CR means you either have to limit your boost, put in lower compression pistons or your tuning has to be just perfect or you are buying a new engine.

The SR20DET and others come with ecus that are boost friendly and internals designed for boost. Plus you can run 300-350 hp all day with the SR20DET. It only runs into reliability issues when you start approaching the 500 hp mark and even then they have solutions to take you higher.

With that said I like the powerband of the S as it lets me make misteaks with my right pedal while driving and it doesn't mess up the car's attitude too much.

But then again I do understand the attraction of instant torque.

If anyone wants to try this experiment I happen to have a low mileage SR20DET sitting in my garage that I will make a good price on to someone.

 

That's all I'm saying.

 

Uh bud, 300-350 hp is nothing. If your point is the sr20 is better based on that, you need to do your homework better. Getting over 300 whp is easy with the s2k and SC'r. Easy, reliable, and a hell of lot easier/cheaper than trying to get an sr20 to fit into the s2k.

Most of the problems with turbo'd s2ks are from poor installs, poor tunes, or a car that was already damaged before hand. There are plenty of s2k's running 350-500whp happily.

 

Knowing that 300-350 hp was a common goal in the S, my point was that 300-350 hp has almost a stock reliability in an SR20.

I have never seen a reliable 300+ hp out of an S.

What S2000 owners are calling reliable isn't the same thing that other people call reliable. You can beat on an SR20 for years at 300-350 hp with nary a hiccup but the forums are littered with posts of blown FC20s.

Yes it can be done. Yes it will last for a while, but engines like the SR20s have gone thru the teething stage that the S is going thru now and there are tried and true formulas for getting almost any hp reliably from it.

There is reliable and then there is RELIABLE.

 

Wouldn't it just be easier to buy a Nissan? Save all of us the trouble of seeing a perfectly innocent S2000 being molested by shoving something up it that doesn't belong.

Some honda dealerships honor warranties for superchager installs. 300-350hp seems reliable enough to me?

Some people just have to be unique

 

We've got guys running 300+ for years without a problem. There's people in here with well over 100k miles on SC'rd s2k's.

Your making the mistake of taking a few people posting problems and assuming that's everyone who owns one. People post when they have a problem, not when things are running great. Its called human nature.

For every 1 post about a FI problem, there's 10 more who run perfectly fine. Most problems are run of the mill every car in the world has them problems, parts go bad in ANY engine. Then there are the duffus problems, where someone doesn't know what the hell they are doing and is there own worse enemy.

Do you know how many goomba's clear a CEL and have their engine blow up two weeks later... That could have been fixed by reading the code and replacing a spark plug? Or a timing chain tensioner? Or someone tried to do some dingus mod and messed it up?

Don't blame the engine, 90% of the time its user error.

 

The point of this thread was not to ask, "does turbo'ing the S2k suck?" but rather to ask if anyone had put an SR20 in a S2k body. Regardless of the reasons why the question was asked, the answer could have been "no". sheesh...

 

no, a headgasket can be swapped out which is a lot more cost and time effective than replacing pistons.

but again, it's just as easy as aftermarket turbo'ing any other car.

and "not easy" compared to what? finding a way to custom fabricate a way to install an SR20DET engine/tranny? lol. I find irony in the statement that it's not easy to turbo an S2k, and that is used as part of the argument of the far more complicated and difficult process of trying a non-oem engine swap.
