high CR with turbo

[diamond_rev]

Whats up guys.. i just bought wiseco 10.5.1 pistons because i was going to stay n/a. but now i wanna turbo my 420a.. a friend of mine said that i can turbo with high comp but with low boost... would it be ok to do this?? or will i get detonation or other problems? thanks

People have done it. I am thinking about doing it and there really isn't that much information about it though.

It sounds like it takes some good tuning and that you would probably want to use premium fuel.

Maybe someone else could throw in some mroe information on this.

As some of you guys know my car is having some problems and I was thinking of finally doing my complete overhaul I wanted to. I would start just building NA and then over the next couple years maybe throwing together the turbo parts.

There isn't a problem with using higher compression with the right tuning and fuel. All I'm going to say is that if your thinking of using those 10.5:1 pistons, make sure you have the pistons fly cut (if needed) and also you may run into problems even with premium fuel. I'm not saying it's not possible, it's just less room for error and you are at greater risk of blowing a motor if your not careful. Motor would make some real nice off boost power though! I say go for it

I agree with 90laserRSfwd Go for it!

The main problem is detonating, which could be helped in many ways. You could run race gas all the time if your rich, perhaps retard your timing some, but most importantly tune it.

High CR and Turbo would be a pretty nice mix, youd have power all over the place.
Now if only you had a 2.4 block,youd have tourqe all over the palce.

Sound like a good idea, High CR+turbo+2.4.

Ps. 2.4 + stroker kit? Has a 2.6 or more been done yet? anybody?

Is it possible? Yes, Will it be Easy? No, I would say dont do it due to the fact it is hard enough to tune a 420a rite now, And if you do your going to be riding a fine line. Now if you to mega squirt i say go for it because then you can get your tune perfect. Summary: For it to work your tune will have to be perfect which pretty much means you need a stand alone ECU.

Dont know that thats even possible....

Can you say traction? High CR+turbo+2.4= tire smoke and snapped axles

[diamond_rev]

im gonna do it. but only on low boost at first until i get mega squirt in.. i still gotta get the lifters, rockers, valves, cams. pretty much the top end.. then i will get the turbo kit. i should be done by august. i will keep everyone posted when i get it done..

[95eclipser]

put a thick head gasket on it and it will lower your CR a bit and a safe tune colder plugs and i think you got it

Apperantly Neons are doing,SRT-4 but still 420a right.
Darrell Cox Racing - 2.6L Stroker Short Block (Powered by CubeCart)

Cause if my 2.0 block goes, I wana go for 2.6 turbo
BigBlock 4Cyl lol

Wrong. Neither srt-4's or 2.4 eclipse's use a 420a motor. I and another memeber which I will not name are trying this same thing and it is doable and yes tuning will be more difficult but like car guy said standalone will be the way to go then it will put you ina position to make it work. If they come out with PnP MnS soon like they claimed it wil be even easier

I looked into this swap, But as Slippi84 its not an easy deal by a long shot. In the end i decided to just keep the 2.0

How is anything "PnP" supposed to work on a hacked and modified car with an entirely different engine? If there are any changes to the sensors, etc., it probably will not be a PnP affair.

It's been done before. 2GNT with highly customized 2.4L out of a Stratus. Unfortunately, the shop that did the build down in Texas was fairly inept. After the car changed hands, it underwent a great deal of clean up and proper tuning. Ended up putting just over 300 to the wheels. Less than impressive.

Exactly.

Those who can't handle the installation of a non-PnP tuning tool should seriously reconsider their build goals. There is really minimal-to-zero aftermarket support for 2GNT 420A tuning, so if you don't want to learn to install the one proven tuning package, then don't bother building a powerful 2GNT, as it's only going to end in tears.

10.5:1CR with forced induction is doable. Keep a close eye on your AFR and EGTs. The ability to adjust ignition timing will be paramount. I would suggest anyone with serious aspirations for their forced induction 2GNT to make MS one of their first purchases. Even on a stock 2GNT, you can become familiar with tuning and see the benefit of improved economy, which will save you money between fill-ups.

What do you mean? I think you thought I was referring to PnP used with a 2.4 swap or something like that I was just talking about with high compression piston turbo setup not the other crazy setup stuff he was talking about with engine swaps.

I disagree with this statement. I would not try and tackle a full non PnP MSnS install even though with enough time and research I know I could probably do it I wouldn't. Yet I know how to tune and the key things to look for when tuning. I tuned my 90 tsi with dsmlink(similar to PnP MSnS) and it took me all of 10 minutes to install.

My suggestion wait for MSnS PnP get a wideband with logging capabilities and a egt gauge and the sky is the limit with tuning capabilities. Not to mention the fastest 420a on here with the exception of Hahn's car is a turbo 420a with portfueler(PnP)

Doing a non-pnp MS system isn't that hard to do. Any you get to keep the ECU inside the car if you so wish to (who wouldn't).

There wouldn't be a line as long as there is for the PnP MSnS if it wasn't that hard to do. This picture says it all to me.

That picture scares me too. I could probably do a non pnp mega squirt also, but i really dont wanna risk it.

Exactly cause I am def not gonna rebuild this motor like it is again if it pops. I got a gift with the deals I got to get where I"m at.

To the OP. ^^^^There is your correct answer. Need to be careful on your tune.

Yeah what driggs said about tuning was correct about what to look for and keep an eye out for.
