safe for 16g?

[yepes281]

So i have a 16g ready to install, but my mechanic keeps telling me not to put it on due to the mileage on my car. it has 170000 miles. Okay or a no go? Hes a v8 guy and doesnt know the durability of a 4g63 but i figured ide ask people with the first hand experience.

 

[miller97tsi]

should be ok as long as you have all of the supporting mods to go along with it

 

[yepes281]

Ive got everything for how much boost im going to run, i got a wally 255 fuel pump, and im only going to run 14lbs of boost.

Make sure all preventative maintenance is done first. A common mistake is to go replacing the turbo first. On a 170xxx mile car, I'm sure there is plenty that needs loving. Just make sure you've taken care of all that, and like miller97tsi said, all supporting mods.

 

[96eclipzGsT]

Bolt that shit on and then run down that v8

 

[mosul210]

What boost level do you expect to run? As long as your vehicle is in good working order I don't see any problem running stock boost levels. If you wan to crank up the boost you will need to ugrade the fuel delivery - pump, injectors, etc..

For FYI I put a small 16G on my 90 Eclipse with 101K miles. I am still running on the same engine/turbo at 15psi with 130K on the engine.

 

[miller97tsi]

do you have the install kit for it as well and when you upgrade your turbo you need to remember that bigger turbos blow more air than you stocker so you just want to make sure that you dont lean your engine out you know

Bolted on my 16g at 195K here!!!!! Don't let that mechanic wrench on your car any more. He doesn't understand phrases like "nickle content" and "compression results" and "heat treating" or even "sirius motor" probably.

 

[yepes281]

Yea i got the install kit and enough supporting mods for 14 lbs of boost. When you say preventive maintenence what do you mean? My mechanic says i need to rebuild it and put in better rods, bearings, rings and valves.

Your mechanic clearly does not know a thing about these engines. You could run a 16g as hard as you want on stock internals with no issues, provided your tune is good. Bolt it on and go have fun

 

[96eclipzGsT]

Is the stock turbo on it now? Your good til about 450hp with stock internals.

At the very least, I would recommend doing a head gasket/studs if it hasn't already been done lately. At 14psi, you're not taxing the engine very hard, so you could probably get away with just putting it on (assuming all basic maintenance/supporting mods are in place).

Do you have an AFPR for the Walbro 255lph pump? You'll want one to prevent fuel pressure overrun. Also, something to datalog/tune with would be a good addition.

 

[yepes281]

Ha thats what I told him. Hes goes "if you put that turbo on right now with that much mileage your engines going to explode", and i said "its a 4g63, the strongest 4 cylinder in the world, i can run 400 hp on a stock block." So i was just double checkin with you guys.

i dont have a logger but my buddy does and i have an safc for the tune.

when things start going bad on a stock block is at 25ish psi of boost
i seen bad stuff happen
but at 14 psi you wont need to do any engine work maybe just change the bov
but thats it
good luck
hopefully when you bolt it on
you race his v8 and beat him

 

[yepes281]

Yea i plan on that, he said his 300 hp s10 could smoke any 400 hp dsm, so when i finish my car i plan on making him look like an idiot.

And i do not have a fpr yet. But could someone explain to me fuel pressure overrun and explain to me what it does and why its bad? or maybe just send me a link.

 

[MrBoxx]

The stock fuel pressure regulator has a very small orifice for the return fuel line back to the fuel tank. When you upgrade your fuel pump, the stock FPR can't keep up with the increased pressure, so your fuel pressure in the fuel rail rises. This tends to make you run rich. What you need is an aftermarket (adjustable) fuel pressure regulator to reduce the fuel pressure back to stock levels. It replaces the stock unit completely. Popular AFPR's are Aeromotive's and FuelLab's. Most bolt to the firewall or shock tower, or can be mounted onto the rail itself like the stock unit.

With a 190lph pump, an AFPR generally is not needed. When bumping up to a 255lph, fuel pressure overrun is usually the case, though most people don't notice it because the car doesn't seem to run any differently.

I have a buddy running a stock 1G 6-bolt in his 2G TSi AWD with approximately 280k on the stock low end....the engine's been in three different cars so the mileage is nothing more than a close guess.

It's had a couple different heads and gaskets, but the stock 6-bolt low end is still intact, and it's currently tuned well and boosting 25psi with a TD05H 20G.

Will you can bolt on the 16g and have fun for the while depending on the guy you are. Or you can make sure the water pump, belts, etc. are up and running good. You don't want to rush it and later on the road like a month or so find that your water pump seized or your belt broke bending all your valves. Stuff like that! That's what they mean by doing your regular check ups.

well it looks like im good to go. il let yall know how that race goes

 

[fastfwd97]

Good luck..just to be on the safe side i would go ahead and get the motor rebuilt..I have the same amount of miles on my DSM and as soon as i put on the 16G, the trouble started..so depending on your budget, i would make sure all the maintenance issues were addressed before i start modding it..All it takes is a stop and maybe $80 to get it checked at a nearby Mitsubishi shop..

 

[95fwdtsi18psi]

You should be A-OK. Honestly if you just do all of your maintenance, ALL of it, no skimping Mr.

Go smoke that S10 for everyone on Tuners.

 

[wishnfor4g63T]

hate to pop anyones bubble on this site but i have a b16g fully port/polish 3' exhaust and 255 wally

still stock injectors and logged for knock ---

19 psi no prob's but on very cold days aka 70's i get fuel cut =D

 

[v-mac]

haha that guy is just speaking out of his A$$, i run my dsm all the time and all other four cylinder cars and when im down at my dad and uncles shop all you hear is mustang this and V8 that and how the 4cylinder is a piece...well ill take my little "economy ride" that will throw down the same if not more HP than their V8 that will also walk them down and leave em standin still .....but besides that, if you do all your maintenance, timing belt,plugs, wires, etc and the car runs strong you should have no problems just dont get too boost happy....every car is different brother that thing might run another two hundred thousand miles you never know, love her and she will love you right back!

If he truely said that, which its believable that he did, then it's that v8 horsepower. 1 v8 horsepower equals 2 4cylinder horsepower; twice as many cylinders

You probably won't see 400whp with that 16g with fuel upgrades. But here's all you need to push that turbo to a good 320whp on pumpgas: 1g bypass valve and adapter, SAFC, 650s. You have a front mount, wally, even a tubular header. Your stock head bolts will last, IF you don't see knock. You MUST get a logger. Hands down the best for your car is EvoScan. You have a 99ecu with the faster logging speed and so have even reflashed it with the EvoScan logging cable. So research this. You may have alot more at your finger tips than you think. If they've cracked the base injector location in the code, then you can ditch the SAFC and get more pumpgas power since timing wont be so high.

Then get a timeslip and show it to him. If he's just bark, then he'll never go get another one to beat it.
