Looking to make your car turbocharged? READ FIRST

[needmorpower]

ok here is what i have 84 240 block with a 20 thousandsth shaved off a multi valved 740 non turbo head...gave me right at 200 psi compression on cylenders...i,ve also added a vx cam kit from pdi with adjustible cam pulley....what else can i do to get more out of it?

I'm contemplating a +T conversion for my '91 b230f, and it all seems fairly straight forward- I only have one, rather geographically specific question. I live in Minnesota. The weather here is frequently crappy, so I like the idea of having a closed airbox like the one on my current engine. My question is this- if I perform this conversion, will I need to relocate the airbox from right to the left side of the engine (it's a 240)? If so, can anyone point me in the right direction for more detailed information about doing this? Thanks in advance.

Use a stock 240 turbo airbox. If you're not going with K-jet, junk the fuel distributor, and fab (or get someone to fab) up something that will take its place. It's a well designed unit in my opinion, doesn't look to be much of a restriction. Either that or a 700/900 turbo airbox. Also look around at the junkyard at other OEM airboxes. There might be something good. I used a Chrysler 2.2 turbo airbox on my old +t. Not the best, but it was easy as hell to plumb in.

Is it just me, or does all this sticky tell you to do is search for your own info. Pointless?

we should disable it and see if the "how do i turbo my car" thread

Hello,

Did a few searches based on the lines suggested and turned up nothing for turbo - ing the B20 engine, specifically the B20D.

I had in mind a TD05 since the final cc of a B20 (1986cc) is similar to that of a Turbo 16 Saab 900 (1985 cc).

Could someone please point me in the right direction?

[danger]

hmm seem like conversion of N/A to turbo engine is possible. Anyone can help me in convert my S40 2.4i 2005 (N/A) into turbo.. probabbly add turbo kit, ECU etc...

stupid question but i read some where that the injectors on the turbos carry a different resestance so you can not just plug them in to a na motors harenss with out it not running/throwing codes is this true? thanks...

[MikeHardy]

yeah the turbo injectors are about 2-2.5ohm, NA ones are about 14ohm. i don't think it'll throw codes but it will fry the ecu with to much current.

if you don't want to wire the resistors in you could find some hi resistance ones with a similar or high flow rate (around 300-310CC)

[alpine45]

thanks for the info.

i want to go t+ i just need to get the parts together, and figure out how to do it right.

[McLovin]

I really think we need this thread to be a "recipe" kind of thread. Basically, it should show what all you need to turbo your car when you start with a stock B230F or some other engine. It would be really helpful. I'm not all sure what I should be looking for.

Me either, I just will need someone to help me do it that know what to look for. Any one have a list they could make out of what's needed to turbo a B230F?

[stylngle2003]

guys, seriously. all the info is on the first page of the performance forum. here are some links to get started with. fundamentally, installing a turbo on a 700 or 900 is the same as a 200, as the engines are the same.

so check these out and start writing stuff down

1 quick question about this, can you turbo a regina car with the map sensor? I have looked and can not dig up the info. specifically on this.

thank you very much your first link has helped me greatly..
the only thing i dont like (im running it to) is mega squirt, do you know of another good tunning system i could use?

[stylngle2003]

megasquirt is the cheapest and most flexible, but many dyno shops aren't specifically familiar with it. if you know how to solder and run wire, it is a great bang/buck tuning tool. if you aren't so keen, perhaps buy a later turbo car (700/900) and swap over the entire engine, wiring harness etc and convert your 240 from mechanical to electronic fuel injection. then you have the option of running frpe82's tuning chips in the fuel and ignition ecu's

if I read this correctly, you have Megasquirt already and want to replace it??

Haltech or SDS is what I'd buy if I had the money for a new standalone system

[82bannanayellow240]

yea.. its been messing up lately and i'm just trying to find something more reliable, i may just get someone that has more expirience with tunning it, to tune it.

[black 940]

Any info. on using regina and the map sensor?

[Krisverde]

soooo ive been thinking about +ting my 88 so since it has lh2.2 do i HAVE to wire up EZK?

for the most part I agree with you.

I found this page very helpful...

http://www.pbase.com/740atl/turbo_swap


if some one that has done this swap would be kind enough, to post up all the parts they needed to get, like a shoping list. and post up what system they started with ect, like I want to use 2.2 2.4 efi on my car frist before I try megasquirt, so a build useing megasquirt or cis wouldnt be useful for me, but might be for others. and I would belive the lists would difer quite a bit.

if it comes to it I will post it up, cus I am doing this with or w/o help, my car will be a turbo.

people mention useing resitors to use turbo injectors with n/a 2.4 cpu's. can any one tell me what resistors to use.?

Guys, part of this process is doing the work/research, and educating yourselves on not only what parts you need, but how to make it work. A turbocharged car needs a couple basic things... a manifold, a turbo, intercooler piping, and an intercooler. It also needs oil from somewhere, and a way to return that oil to the pan. If that process scares you, you should not be doing this swap.

I didn't set my pbase up as a step-by-step guide, but I figured that it may be helpful to other people doing the swap. When I did mine, I had nothing to go on.

Have any of you read Kenny's install article on the front page? It tells you EXACTLY what you need. Do you have a LH2.4 car? guess what, you need LH2.4 turbo computers. same thing for LH2.2. Etc.

Not everyone should be doing this swap.

I don't know who mentioned that, but they obviously don't know what they're talking about.

If you have a turbo car, you need the turbo fuel and ignition ECU's. Period.

If you have a turbo car, you need higher flowing injectors. If you use the greentop injectors from a 740/940 turbo car, you need the ballast resistor.

You can also forego the ballast resistor if you use high impedance fuel injectors... such as those found on ford thunderbird supercharged vehicles.

Keep reading/doing research. Before you lay your hand on a tool, you should have a complete mental picture of exactly what you will do in each step.

Remember, turbocharging a 240/740 is not rocket surgery... if it seems like it is, stop what you are doing and buy a turbo car.
