Turbo for carbed engine
Newbie question.
Ive hunted arround the net and manged to find enoughf pics to understand how a fuel injected car would be turboed. i.e. plumbing wise i.e. from the turbo to the air box or the rail. But how do you plumb the forced air for a carbed car. How do you jet it.
App is a 8 Valve carbed 4 cylinder swift engine.
There is a tube feeding the air filter from outside the engine bay. Should my compresed air join this tube. If it does then do I seal off the other entry. Whats to prevent my forced air being forced out what is the intake for the air filter.
Any pics of a crabed engine with a turbo
thanks

Re:Turbo for carbed engine
i was also hoping to earn from this, but since you said read, and he prorobly did and thus said for injected cars, alas he has a carbd car. i might get myself a carbed car aswell, and i was hoping there was an answer to that aswell, because dual weber sidedrafts on a damn 2nd gen accord just wont cut it.

Re:Turbo for carbed engine
Is it just me.
Am I on the wrong forum.
But for every technical post there there seems to be 20 that servers no purpose.
Im a technical advisor on VSAT (Satalite) networks. And as a hobby run and moderate a number of technical forums for Two Strokes. rddreams.com and macdizzy.com
Im married with two girls aged 8 and 3.
Hows that for a totally pointless off topic and total waste of a responce.
Ive spent the last 3 weeks reading every single Newbie post. And cant find answers to any of my questions.
Ps: The Carb issue is relavent cause my two stroke motors dont come with fuel rails. And I know a ---- load of two strokes have Turbos installed. If you dont know an answer. Calling me Gay dont cut it.

Re:Turbo for carbed engine
turbo charging a carb engine is a real pain in the ***.
1. you practically have to guess ( experince eliminats guessing ) the carb settings ( jetting ) along with the boost.
then you have to get your carbs pressurized
( its relitive in cost. from $25-150 a carb )
then your manifold. ( fabrication ) and your boost limitations i think the carb limitations are like 3-15psi depending on the carbs.
what type of turbo carb system.
carb before the turbo or after.
its just easier to build Efi from spare parts and stuff...

Thanks
Easy dont intrest me.
Turbo before carb.
Single carb.
Plan on runing 8-10 PSI.
For the RD the plan is build a 1x2 manifold and run a 40 mm lectron. Extra fuel will be controled by a selounid based power jet.
For the car Im planing something similar an extra circuit / power jet.
I build Digital Programeable CDIs with dual stage revlimiters and Digital EGTs for two strokes to the electronics is not a porblem.
Manifolds are not a problem. Have acess to a complete CNC machine shop and Tig welder.
Already started word on an air/water intercooler.
The really hard part is sourcing the basic Turbo from half way arround the world.
Narrowed down my list to either a T25 or a K03. Or an IHI RFB5.
I know the smart guys are geting them for 75$ off dsm.org or 35$ from the junk yards. On ebay they are going for crazy prices. With coments like only done 40,000 Miles NO SHAFT play right.

Re:Turbo for carbed engine
you might wanna look at what this dude with his ecort. its essentially the same concept.
http://www.student.uwa.edu.au/~smcca...rt/escort.html
he put the carb befor the turbo.

thats so bs. I have an mk4 escort with a weber carb on it and i can pump the boost up to 25 psi, without re-jetting it . you just have to check your plugs for the first little bit. as for pressurizeing the carb just plug all of the holes and make sure you have a weber or dulorto

Re:Turbo for carbed engine
how long have you been running 25psi On what style of turbo system. ( blow through or draw through ) are you running really rich on the low end.. what are you using to compisate for on and off peak boost.
how many sets of plugs have you melted
as for dellorto and Weber carbs they are only way to go.. they can be spendy ( if your in the US ) ( try ebay. )
webers are $100 used on average. ( 40mm, 45mm )
well please be specific on your turbo system. in that regard. its hard enough to set up a relaible system ( not like allot of tunners let these secrets out )..
