Chevy S10 2.2L Performance Mods
Okay, some of you guys have asked for a 2.2l performance sheet… well here you go
Chevy S10 2.2L performance Mods
Okay, so, some of you guys have asked for an “Engine build thread” on my findings of the 2.2L performance mods. So here is my build/and idea/ research thread.
-My Current mods-
• Custom cat back exhaust
• K&N intake
• Polished throttle body
• 4.10 gears
This here on a new motor could make about 110 – 115 at the wheels, maybe more.
1.) First mod I think you should look into going with a lift kit, or long travel (LT), is re- gearing. You do not get any horse power (HP) out of this, but it defiantly feels like you do cause of those bigger tires and wheels you have added.
2.) Basic mods for just the begging for better MPG and HP is an intake (K&N). And then get a replacement muffler. Such as a flow master, Gibson, magnaflow are some of the best on the market. Now if I was going to do this again I would get an Original 40 series flow master. And if you’re lucky you stock cat,Is a bolt on and bolt off, and you can go get another one from your local muffler shop or junk yard and punch it out, and keep your stock one so when you need 2 smog it you can put the stock one in and pass smog .
3.) NOW… if you want to get into some serious stuff like I am going to get into and will post my results in this forum. You can get into motor stuff, you can get a turbo kit and all that, but there is only so much air and fuel that you can pump into these things, with stock hard ware. (Intake manifold, cylinder head ex.). So imp going to take the already chocked up stuff on this truck and open them up. Now I have aside a complete rebuild kit for my truck, complete everything I need for a complete engine and clutch over haul. When I install all this, I am going to take the cylinder head down to family friends and there going to show me how to port and polish the cylinder head, and by me doing the work and paying attention and stuff, will let me learn something and also get it done for FREE. Then ill take these learned processed information and do the Intake Manifold my self. Both of these stock are VERY restrictive and can really open this truck up from what I have been told and reading I have done. (SOON TO COME). For about $500 dollars you can also get a cam. But the improvement is not worth it.
4.) Now I have taken the polishing technique and polished the throttle body on my truck. This isn’t a real power improver unless you step up in size or port and polish it. By polishing it like I did, I think you might see a little better gas mileage and runs smoother. Now I know for sure that it runs smoother and had better throttle response but MPG I do not know of yet. Simple to do and esay and every little bit is worth it on this truck, and you learn a thing or to.
More HP and MPG different stage packages:
Stage 1-
• New muffler
• Intake
• Polish intake
• Under drive pulley
• Good spark plugs and wires
• Re-gear
Be around 110- 115 Rear wheel horse power
Stage 2 –
• All the above
• Port and polish cylinder head
• Port and polish intake manifold
• Jet computer chip
125-135 RWHP depends on vehicle mileage of motor
Stage 3 –
• Stage 1 & 2 + listed below
• Cam
• Turbo
• Custom cut pistons blah blah blah.
+200 HP
If you’re that stupid to put that much money into this motor then have at it. But it’s not worth it. Put the money in something else.

great write up!
the only things i would add or comment on is:
im thinking that with a ported inatke and head that the cam really would be beneficial and allow the motor to take advantage of the new air flow capability…. although i would agree in a stock app prob wont benefit much. also the 4.10 gears are the stock ratio in the 4 cyl manual ext cabs, not modified.
the other stuff not mentioned is doing a header, custom piping all the way from the header back, with a high flow cat, that will help alot with a cammed, ported motor. also sounds bitchin!!

Pacesetter and obx, but trx and i are working on making one for the 2.2 i am helping design it with him and he is making it.

Look on http://www.dts2.net you can find turbo KITS with stages 1, 2, and 3 these can produce up to 400 hp or more if u build your engine up more. they also have a lot more performance products on their website. check it out.

you all might think them 4 cylinders are bad i cant lie i have one myself that i lowered put the exuast on for sound, chrome wheels,custom paint job and all that but you have to think the transmissions is what you have to worry about there made out of weak metal that will pop in a heartbeat with to much power i just got another s10 and put a 383 crate engine in so good luck with the 4 cylinders they are cheaper on gas trust me.!!!

you guys seem to have a lot of power adders figured out but you left out quite a few. first give the block a 1.5 mm bore,use some federal mogul 90.5 mm hyperutectic pistons,eagle h-beam connecting rods,and get a better cam. then port and polish the exhaust and only port the intake this leaves a rough surface to give a better fuel mixture. the 1998 and up have a decent composite intake just make sure to port match the head and intake to the gasket.a throttle body spacer will give a good torque gain. of course an air intake is always a good adder. as for exhaust i used pacesetter header magnaflow high flow cat and gibson swept side exhaust.i also used accel dis coil packs accel plug wires and e-3 plugs.a 180 deg thermostat is required when using the jet stage 2 module. the cam builds power in the 1500-6000 rpm range so if your using an automatic tranny youll need a higher stall converter. i have a 5spd but i did need a zoom stage 2 clutch and a detriot tru trac rear diff,but the wheel hop was bad so i had to put traction bars and wider tires on it. i do have a nos system on it but i was conservative with a 50 shot.all of these parts but the cam are available from summit racing but the cam (was a custom grind). i hope this helps any of you get on the right track to building your 2.2
