With the right pipe you can expect better idling, throttle response ect

What's a good pipe for my 3.3?

The hobby shop (when it was here) replaced my piston bearings and I think the rod FYI

I ordered a hitec 645mg servo for steering not sure if it's a bad servo any input on the hitec?

For that price, it's an excellent upgrade over stock.

Ok on the exhaust pipe I added copper tubing to shoot the exhuast out the back to avoid oil all on my wheels lol does this cause a issue with back pressure ?

Start with just the silicone deflector. When everything is tuned and running well, only make ONE change at a time and tune to that change, if necessary.
Basically, don't change glow plug temp, fuel percentage and pipe at the same time. You'll have nightmares trying to figure out which change is causing your problem.

 

[John connor]

Good one Rolex I'll keep that in mind now lol

 

[hotrodrob]

Great advice @ rolex

The ths pipes arent bad at all but if u got the cash you can't beat one from ercm

 

[John connor]

May have to put it on at a later date
Looking for that pretty penny first lol

 

[hotrodrob]

Ths pipe and header for 35$ on the bay

 

[John connor]

I feel dumb now the exhuast I seem on amazon was 89 lmao but that's not bad at all

 

[hotrodrob]

Really gotta look around on those sites, theres usually 10 different prices for the same items from different sellers

 

[John connor]

The reason I try to stay with amazon is I'm working off iPhone if I had a laptop it would make it easy lol

 

[John connor]

front end with new axle carriers aluminum bulkheads shocks are still good and decided to leave most plastic researching for further parts

Rear end is next then motor and trans

 

[John connor]

Got it all back together last night and test drove it and it held up great wrecked it a few times bulks are holding up

My issue is I can drive it for about 15 mins and it will start to loose performance and start overheating (smoking pipe and head) everything still spins and still cranks up but not sure if I'm running it too long or too lean

 

[hulkmaxx]

Sounds like its running to lean if it's smoking from the head.

 

[John connor]

It has exhaust smoke only when I get on it

And the big adjustment is that the one that controls lean or rich fuel?

 

[Nitrotrout]

It may be your LSN is too lean. Pinch test your fuel line, it should stall out within three to four seconds.
The big adjustment (HSN) is the one that controls lean or rich fuel for high speed. Clockwise is lean, counter clockwise is rich.

Try tuning with half a tank of fuel. You may have a half tank lean issue. With this method, the engine will run slightly rich with a full tank of fuel
and lean out and run stronger as fuel dwindles, without over leaning/ over heating your engine.
