Max boost with factory tune and fuel system?

[BadBlackX]

I have a '00 2.2 5 spd non flex fuel truck. I also got a good condition DSM T25 and intercooler given to me by a friend. Out of a '97 Mitsubishi Eclipse GS-T. Low miles on both parts and they look good. He owed my $$ for mechanical work so we bartered instead. Debating on fabricating them onto the 2.2 in the dime. I know it has been done. BUT, is it possible to use them on factory computer tune and fuel system??

Fabricating the system is no problem, been building street/strip cars for years. But I am normally a nitrous guy. Have my S10 that has been a great DD, but needs mo powa! So am I nuts to think I can push 5-6psi max through this thing? Maybe less. Even to get a gain of 40-50hp would be a nice upgrade for little money. Need to keep it sane as this is and will continue to be the DD. Gets 29-30MPG and needs to stay there. Some impressive turbo builds on this board but not after an all out type build. If I can add an electric fan and fab up the turbo and related parts and get away on stock parts/tune otherwise I think I know what I have planned this winter.

So can the factory ECM & tune as well as the fuel system handle 5psi?

you can push about 5-8 psi without blowing the 2.2L up. reguardless id get it tuned. not sure about the fuel system. and if you stay out of boost you will be able to keep your gas friendly 2.2L in check with 26-30 MPG

BadBlackX,
you say you are a nitrous guy.
so would you run a 50-75 shot dry on this truck?

basically my point is without at least proper fueling you risk causing problems for the engine and the turbo.

[BadBlackX]

Knew it was a long shot but can't shoot for asking..

So I can easily add a Walbro FP since I have my stock bucket. Easy & cheap enough...

Injectors. What would a good size be at this level? 5psi... maybe 120-140 RWHP...

I have a shop I have been in contact with that has HP Tuner Pro and can tune the truck on a dyno with a WB A/F just to be safe. Says they have not played with an S10 but they tune some serious LS stuff and have a good rep. Plus they are local to me...

I was hoping to build the system and drive it some to see how I like it or not then move from there, get the bugs worked out. Again no large hp goals, got the camaro for that realm. Just looking to add some grunt so this thing can get out of its shadows way and make the commute a little less ho hum. Trying to set a target budget of $1000-1500. Hope less than that as I have the turbo and intercooler already. Laying it all out on paper to see if I even have a chance at that low of one.

Being as yours is non flex fuel, I don't know if the fuel system(specifically the pump) will handle even that small of an amount of boost. And risking it, especially without a tune, would be asking for trouble. Having at least a rising rate FPR would help keep you from running lean...

It's pretty pricey though, you could drop the $500 on HPTuners and $250 on injectors and tune it.

The 2.2 internals will hold up to 10PSI. cs xtremes spiked to 14 with no damage, but he ran 10 for quite awhile with no problems...

Oops, posted my post too late :P

i agree with all of the research i've done you can run 5-6psi with intercooler and definetly use a 9:1 rate of gain rrfpr like he said or a vortech.if you go for injectors stock are 17lbhr which is good for 35hp/cylinder @100%duty cycle which is not recommend so use .80%=28hp p/cylinder and that doesn't cover enough.a 24-25 lbphr injector will give you @80%duty cycle 160 hp range that would cover the range you want.i've been told that it wouldn't be a problem for stock and rrpr for low boost your call.

[What?]

You will be able to achieve your goal no doubt, tuning is where it's at as you would know, HPtunre and you'll need to upgrade fuel pump, Aeromotive A11109 or Walbro 255.

You can run up 50, 75 wet on 2.2L, some has done that with no issues and turn out well.

Be sure to keep us posted with progress, pics and such, love to see how it turn out.

if you can get you ecu tuned properly u will probably be ok on 4-5psi, im am currently running 5psi on stock engine, no tune, but i do have the flex fuel pump and run the e-85 which lowers my chances of knock, i rarly get on it hard knowing it hasnt been tuned, and afraid of running to lean! if u get it tuned with hptuners, u can def go to 8psi with an upgrade in injectors prob 44lb is best for that, and if not flex fuel may want to lookinto somthing for that, and u should be very safe on stock engine with those things done! u can def feel the difference on 5psi, its so much better and great gas milage increase! btw ive had mine for almost 6 months now with no tune on 5psi and stock engine and she has ran perfectly fine! but i dont do anything stupid with it either! lol at least not till its built up anyway!

[cs xtreme]

5 psi should put you in 150-165hp range give or take, with a tune though.
from what I've herd the stock pump wont take the extra pressure from an fmu. but I dont know since my truck is flex fuel.

[BadBlackX]

Will not build a potential break down so a Walbro is in order. Also plan to add adjustable FPR and bigger injectors. That way fuel is in order and once tuned should be dead reliable. Can't stand a vehicle that isn't so....

150-165hp is right where I want to be. Nice for a DD so I don't get myself into trouble on the commute, but still should get some killer MPG.

You better get yourself an aftermarket wastegate actuator, or do an external gate on that thing. T25's in eclipses were set at 11-13psi factory....

[cs xtreme]

I must warn you boost is like crack. and when its so easy to get more with the simple turn of a dial on a boost controller it can be really bad.
5-6 psi will give your truck a swift kick in the ass. but it still is just a teaser.
I think I ran 5 psi all of maybe two weeks before I bought a controller and started going up.
but just a few extra psi requires a lot more fueling.
and at 15 the truck is pretty crazy.
it actually keeps me out of it more because it wont go in a straight line below 45 on street tires when I floor it (back tries to pass the front)
kinda fun having an engine that started soo gutless now do what it does

Good to know. Still very green to turbos. Would a manual boost controller work or is that something else I would need? I can get one for free. Best friends lil bro has been selling them for years on ebay with great results. Said he will send me one if I need it...

I see you run the T25 IIRC? Can you give me some more details/parts used on your build. You spent $500???

Yeah I can imagine. That's how the bottle is for me. Remember the days when 100 pills felt like a cannon shot. To think I am now plumbing a fogger to come in after the plate. Nothing like smacking a healthy small block (480fwhp) with 300 pills. A mild 11 sec street car turns into a high 9 terror. So I can imagine boost is similar.

Honestly the plan is to use the truck to learn about turbos. If I like what I feel and see I plan to build a twin system for the camaro. Love the juice but these turbo cars move out at the track!

I won't deny I have priced out engine parts like in your build for more boost if I like the turbo. I can get Eagle rods pretty cheap as a buddy is a WS dealer. He also gets Probe but I haven't researched if they make pistons for the tutu. But that is way off. Right now I just want to plan it all out on paper to see if I can build a nice lil budget system (like to keep max at $1000 before tuning) and keep the truck reliable. Build from there.

[1tuffs10]

if you know how to do the fabricating part yourself then yea should be able to do on a budget pretty good!! and yea ur right that the boost is a big tease on my synapse wastegate all i have to do is turn the screw in or just put the stronger spring in for more, but i know i cant!! even though i want too, but im still happy with the results!!

[A CLEANMACHINE]

remember a boost controler can only adjust boost above the actuators setting nothing below it but if you have actuator set to high for your liking i'll tell you how to get the boost down from a higher wastegate setting.

I would appreciate this knowledge....

[A CLEANMACHINE]

by using a compression type spring[mcmaster-carr]and adjustable actuator arm,it works.add washers at both ends, you can remove some to adjust or add.

[BadBlackX]

Nice!! Thank you!

[turboS-10]

You can get brand new aftermarket wastegate actuators set for 8psi and adjustable down to 6psi for about $50 too. It's cheaper to modify one but easier to change it out.

[southernrock20]

I have been running 12psi on my stock internals, but I have upgraded ignition, fuel, and its been tuned. I also am running a snow performance methanol injection kit to be able to run that high of boost on stock internals. 10 is the highest I would go on stock internals with a good tune and upgrading the ignition and the fuel systems. The guys at the dyno shop says adding the snow kit lets you run more boost, get more out of it, and runs safer. Its something to look into.

[Redd]

the snow kit is pretty good... Had one on my lightning when they first came out..
