Start Of My 1.8l Turbo System

[civickiller]

yeh its called a snorkel. i believe both 1.8 and 1.4 guys have it, and there are a couple of people that actually took it out, and ran a pipe from the engine bay to the bumper and cut out the fog light area for a semiforced cold air intake to the actual intake. oh how do u pull out the door knobs?

The knobs will just twist off revealing the chrome/silver lock rod underneath.
This chrome rod needs to come off on the back door or it will push any plug that you put in out of the hole.
I left the fronts in and havent had any problems.
A simple plug from Home Depot or Lowes fills the gap nicely.

im thinking that i am going to take sonicsteves advice and use my holsets and rebuild one the fits my needs or if all else fails i might be able to trade and get a properly sized turbo. what diameter exhaust are you going to use for your manifold and then your down pipe?

 

[SonicSteve]

Well my primary tubes for the mani will be the size of the stock most likely. Or whatever closely matches the head. Then my downpipe will probably be 2.25 along with the rest of my exhaust. Thats plenty big for this car it should breathe just fine for this application. Did preloader go with a larger dp or did he end up running the zzp?

I'd recommend getting the model number, then the compressor map, and plotting it out to ensure compatibility; or have a pro analyze it for you.

Turbo selection is insanely indepth. Will the turbo run into choke or surge, what RPM will your boost threshold be? What part of the efficiency island will the turbo be in for most of the Rev range? If these are unknowns the turbo will likely be suboptimal.

Check out Preloaders "Turbo Selection" thread for a sneak peak into turbo sizing. Use the "advanced search" for Turbo Selection and it'll pop right up.

He's currently running the ZZP, a 3" DP will likely be bolting up to the upgraded turbo..

I'm loving your progress so far.

 

[SonicSteve]

Thanks sx. And yes turbo selection is crucial. The only reason im so relaxed about my turbo selection is simply put. This is a test/baby system. My system will be quite small and require very little boost. Or rather. The 1.8 guys will be limited boosting stock. Im not an expert on boosting but im learning as i go here. The 10.5.1 cr of the na motor will limit me to 5-7 psi. Im afraid and have heard that going over that number will most likely show us engine failure points of the 1.8 with that being said... There is a large number of the honda crowd using boost on their 10.5.1 cr engines... And having great results... It seems my greatest challenge on this setup will be tuning the car in to perfection. Which i hope trifecta or ddm will be helpful here. I will need them. There is a pretty typical gain of 100hp of 5-7 psi across many stock higher cr engines. More power can be made yes definetly. But the "safe" boost range on an originaly na platform is yeilding great results. In the future there will be a build for a 1.8 built specifically for boost. For now i hope im heading in the right direction. Anyone with any useful info or questions for me to help me build or design this system pleeaasee dont hold back. Anything helps. Except haters. Move on lol

trust me, for me to putting a turbo on a car is not something light hearted. and from what ive seen so far everyone on this forum has been very smart about altering the sonics and to acheive the threshold of safety levels, by doing a lot of research. i would never put a turbo on a car that wasnt correct for it. one of the problems living where im at is the total lack of racing/street racing and so consequentially there are no performance shops near me; but i will be searching for pro turbo guys to ask for a taste of their wisdom. also hopefully i can follow the foot steps of the pioneers in this forum the first chance the money gives me...

 

[SonicSteve]

well it seems as though you have as much drive as i do.
quick story time cuz im feeling sentimental. i bought the sonic for my ex gf. we broke up and i decided i wanted to mod the hell out of it. i then started diggin into every bit of info i can find. i found what i considered to be the sickest sonic ive seen to date on google, and i basically vowed to build a car damn near identical to it but in my own way and as badass as i could possibly pull off.
heres the fun part, turns out the car that inspired me to want this project is preloaders. lol right i didnt know it at the time but i was browsing around here and saw the car again and about died. since that time i just want to build as fast as i can and build as much as possible every day. so thanks to preloader. go read every post you can from him it is very much so worth your time. i hope when all this is said and done we can have some rediculous major sonic meet and all of us can race, at which point the panda preloader car and my soon to be panda cf and white 1.8t can run...which im sure will be close and sick as hell orrrrr i may be daydreaming again lol. the info on here is everywhere. and look closely into people builds take everything you can and learn. most important thing; BE INSPIRED

hey guys, need some help. i need to know the lph on the fuel pumps in the sonics 1.8 and 1.4 im trying to see if the fuel system will keep up and i dont want to run an external huge pump and regulate the hell out of it just attempting to sort out what the system makes and if it will keep up. also, on injector selection, everyone seems to be swapping to 42lb bosch injectors whether they need them or not. is this our only injector option?

 

[sx sonic]

Civickiller- Looking forward to what you come up with.

SonicSteve- Not sure when the fuel pump will maxout. So far It's been good enough for 200hp, so I'd guesstimate it good up to 250hp.

Same with the 42# injectors. I'm sure you can find larger injectors if need be, Pre may be going to 60# to support corn

 

[civickiller]

time to break out the reading glasses haha yeh im a gear head at heart, but u unfortunately my dad's not, so it forced me to self teach and learn everything myself. also with the custom manifold i did hear talk that the cruze turbo kits would possibly fit. so you could use the exhaust manifold. and im pretty sure that the endtank kit that makes the cruze n/a engine a turbo is using a garret 25

 

[sx sonic]

Pre's using a modified stock manifold on his build. DDM already has a Gtxxxx attached to it

sx, where are u at in illinois? jw

About 20 mins south of Joliet.

word of caution my front lock knob deletes went fine, worked fine for a few weeks till the day the lock rod got stuck under the plug forcing the car to automatically lock and re lock the front door. rolled the window down and found the rod stuck under the door panel edge, i have since added a short 1- 2" piece of vinyl tubing to the bottom of the plugs and slid it over the rod to act as a guide no problems since and that was 2 months ago.

second word of caution on deleting all the plugs in the car, the unlock button inside the car will not function if the car is locked via the remote. which means if some one locks the car with the remote whilst someone is in the car they have no easy way out with out removing the plugs to access the rods to unlock the car.

Firstly, the car WILL unlock from the inside if it is locked with the remote, not only is that a safety issue, but I have done it myself.
Secondly, if the doors are locked, pull on the door handle once, that unlocks the door. Pull on it again and the door will open.

 

[civickiller]

thanks guys haha yeh im still reading bout the turbos and i wanted to start looking into low compression turbo pistons and rings and rod upgrades for the car

 

[Preloader]

Somehow this thread turned into a door lock delete thread, which already exists. I removed all the lock rods from the door interiors and plugged the knob holes. It's been over a year, and not only have I not had any issues, but actually have had a piece of mind knowing my car is unslim-jimable.

Also, I've researched the lower compression rod idea, and came to the conclusion that it's not really necessary unless you plan to boost above 30psi. When force inducting an N/A engine it's sometimes wise to lower compression, but since ours is factory charged we already have a relatively low CR. 9.5:1 IIRC.
