boosted 1.6L

[peepsalot]

You guys run MAPs instead of MAFs?

 

[steve_protege]

yes its true our low compression helps boost more. valve job ??? u have an automatic ?

Yeah, never learned how to drive a stick.

 

[Shane5425]

going manual i think ... we will see ... im going to be seeing someone tomorrow about it. maybe he knows something better to do to my auto tranny

[steve_protege]

Huh ??? We have the same compression as 2.0L's....9:1....

He asked with lower compression pistons could we run higher than 20 psi ?? I imagine you mean on otherwise stock internals ??? Possibly..that might be pushing it on stock rods,then again with GOOD tuning, maybe so......

Not necessarily higher than 20 PSI, but maybe starting lower first. Maybe with the lower CPs we could run 10-12 PSI without a whole lot of tranny slippage. But yeah, everything would be on stock internals until one gets a better valve job and torque converter. Then with the engine management and proper tuning, up over 20 PSI would be feasible.

if i am not mistaken , hiboost runs a map 2 bar map sensor..

correct except 3 bar

nice, i got the same kit kinda, lol i got the same mani,turbo,downpipe, and i had the vortec but i sold it, and got a rising rate, i run 12 psi daily, and have yet to dyno it, but it feels real good. what FMIC are you getting??? and how are they gonna run the piping??? dont mind the diamond plate heatshield, i made a new one.

here is the new heatshield!

at the moment I'm running 5psi non-intercooled. it's a 2nd generation mitsubishi eclipse turbo custom welded by WagnerMotorSports. I bought the kit used which ran me 2200 including installation. fuel management is vortec 12:1. I've had the kit for almost a year and a half now. I had an oil leak coming from the oil pan the week after install which was a 400 dollar fix. Then about 6 months later the turbocharger itslef blew. I got a replacement off ebay with 7k miles for 150 bucks. no problems since. FMIC is due in july so I plan to up the boost (10ish). After that I'll put it on the dyno. The kit ran 165whp w/IC (not fmic) at 6psi off the protege it came off so we shall see.

also i chose this intercooler because of how simple it was to run piping, if you get a traditional intercooler with the piping on either side of the intercooler then you will have to run the piping weird, and have more of it, i have very little piping with the setup i got, there for less lag.

also i have no idea what size piping you guys run, but i run 2 inch, and it is far better then the 2.5 inch i ran, when i ran 2.5 inch i had lag upto 3.5-4k, no i reach boost at like 2k, no lag what so ever.

Just wanted to say that the new heatshield looks awesome. Where did you manage to find it? So instead of the normal 2.5 inch piping you run with intercoolers, you ran the smaller 2 inch piping and had less lag? How is that possible? How could you have more lag with bigger piping? Wouldn't it be vice versa? With the amounts of air coming into the IC, it would all have to then be constricted to fit in the smaller piping?

 

[THEGOLDPRO]

i made the new heatshield, then painted it, then slapped on a mazdaspeed decal.

it has less lag because its a small motor,with a small turbo, so if you go too big of a pipe it wont flow as good.i only speak from experiance, my old setup was 2.5 inch with a traditional type intercooler, and it felt bad, no power belew like 3.5-4k, then all of a suddin boom power, with the new setup, and smaller piping i reach full boost much lower.

you gotta remember this isn't a twin turbo supra pushing assloads of air, its a small 1.6 litre.

 

[MIA protege]

interesting comments goldpro. im running 2.5' and it does hit full boost around 3.5k ... hmmm

what about ur exhaust ?

im sure ur right, but theres 2 sides to this im sure also. theres ups and downs to running smaller piping. yeah u might reach full boost quicker with the smaller piping but u might be losing some power, im not saying a lot but im sure some. only way to tell would have been to dyno it with the 2.5 piping then with the 2' piping u got on there now. with the 2.5', it might take a lil longer to reach boost but less power is lost. im assuming here.

 

[Protege2K]

What good would that extra power do if you couldn't even use it til very high into the power band.

 

[MIA protege]

3.5k is not very high

 

[Protege2K]

That is very high when you consider the point he is barely spooling.

 

[MIA protege]

barely spooling ??? whatever u wanna think. i was just making a point that it can go both ways. people want different things. not everyone thinks like you or gold. you guys might want fast spooling while others want max power .

 

[Protege2K]

Having a dyno queen built for you I see. It woudl seem to me that since these cars are our daily drivers you would want quick spool time. Unless you just really like racing on the interstate. (yawn)

 

[MIA protege]

unless i like my gas

 

[Protege2K]

[God I hate to get into this kind of arguement] But, I bet my car with larger engine and quicker spooling turbo gets better gas mileage. A turbo won't hit boost the second you hit the gas, I can control mine with ease to get better gas mileage. Hell I think I get better gas mileage now then I did when I was N/A. That is of course when I drive normally.

 

[MIA protege]

i dont cuz im auto ... u can control your gas mileage a lot better when you have a manual. and greg i know u dont hit boost the second u hit the gas , relax, but 2k is veryy quick, maybe 2 seconds after u hit the gas lol
