i have access to 2 93 plymouth lasers with about 7psi turbos on them. now my question is, would it be possible to take every part needed for the turbo off on of these lasers and put them on my s4 NA engine. i can get the intercooler and piping and the wastegate, turbo itself, and every other part nessary to run the turbo. im just wondering with the proper fabrication if this is possible. thanks

 

Anything is possible with a welder, time and money.

But should you bother? No.

 

why wouldnt i wanna. u have a turbo charged na right. or is it the fact it isnt a tII turbo and would almost give little to no effect?

 

Any OEM turbo designed for a 4-cyl. is going to be too small for a rotary.

 

so there wont be any gain from adding it? i mean if it to small cant i fab it on. or u mean its to small to help a rotor.. im sorry about questions i just really thought since i cant get acces to a stock tII that this would be better than anything. or can i use the intercooler and piping and get a bigger turbo maybe a TII turbo.. im looking for the route that will cost the least and produce about 5-7psi. so any help is very appreciated. thanks

 

By too small, I mean the hotside will be dinky. You'll get great spool and a big lump of torque in the low-mid RPM range, then it will fall completely on its face. The torque curve will look like a shear cliff-face.

 

so other words its not worth it? and by fall on it face does that mean worse than before? i respect ur words but they put me in my old position. not knowing what to do about a turbo. any advice on cheap alternatives?

 

As mentioned, almost every OEM 4 cylinder turbo is way too small for the rotary. Hell, almost every passenger car OEM turbo is too small. The stock TII turbo (an HT-18) is actually quite large, if you were to compare it to other OEM offerings. Especially the turbine side.

Putting a small turbo on a 13B will result in an engine that will make great boost just off of idle, but will run out of airflow long before the engine is the limitation. Think of it this way: you floor it and see 14 PSI (actually probably more because the turbo will be far overspun) from 1500 RPM until 4000 RPM, and by 5000 RPM the turbo is only huffing 2-3 PSI. The turbo itself won't last long under this abuse and you'll just be blowing heat into the engine.

If you do want to turbocharge the car, then first look at the FAQ. You'll find a TII swap is far easier. If you do want to go the turbo-NA route, then you have two choices; 1. port match the TII intakes to the engine then swap on all the stock TII stuff, 2. custom fab a setup.

Each of those choices has it's own advantages and disadvantages.

 

ok i totally get it now. tw0 more question at this point, can i get a stock tII turbo and use different intercooler and piping and do a custom fab setup useing the more proper turbo? and second question if i was to tII swap, do i immediatly need a TII tranny and drive shaft, or can i wait till later for those? thanks

 

Yes, you could make whatever custom intercooler setup you want.

Yes, you could use the NA transmission if you swap the flywheel with the NA version. But I wouldn't suggest it. NA transmissions are delicate, and while they can take more power than stock, it won't take it forever.

Read the links in the FAQ for both TII swaps and turbocharging a 6-port engine.

 

I'd suggest that based on your questions, you wait and do a lot more reading on turbo systems in general before you go ahead with either a turbo-NA setup or a TII setup.

 

exactly what i was doing earlier and will keep doing. i no literally nothing about turbos let alone rotary turbos. wish i could pay u arron to help me with this. ive seen lots of your handy work and one day hope to stand in your shoes(or slippers) lol. but yea the more research i do the more i realize im stuck simply from lack of knowledge. i will keep looking up how to turbo a 6 port engine. thanks for ur str8 up responses. ive just decided to throw on a electric turbo with 250 cfm and have it activate at 3800-4k the same spot i have my ports opening.( for higher upper rpm range.) and it seems to be working awesomely.(nothing compared to a real turbo im sure) but its work better than what i had for shure.

 

You're kidding about the electric turbo, right?

I can suggest some reading for you.

Street Rotary:
http://www.amazon.com/Street-Rotary-...3442806&sr=8-1

It is a basic introduction to modding the rotary and written very well with great pictures.

Street Turbocharging:
http://www.amazon.com/Street-Turboch...3442806&sr=8-3

Lots of good introductory information to how turbos systems are designed and how to choose a turbo.

 

Electric turbo = Ebay scam.

 

not from ebay its from mitsubishi. thing runs pretty nice from what i can tell definatly better top end

 

Electric turbo also = the dream of this electrical engineer when he was much younger.

The math just doesn't work.

Personally, I really like this book:

Maximum Boost by Corky Bell

 

The placebo effect is awesome.

 

placebo?......

 

It means you think you feel a difference, but there really isn't one. The amount of current needed to have an effective electric supercharger is extraordinarily high. Your alternator would never keep up with it.

 

i have it run at higher rpms.(only racing do i get up to 3800-4k) so its not active until i need it for a few seconds. the battery runs it off no charge without car running(ran it for about 10 minutes to see if it would have a problem with power or overheating). i quess i just dyno it with and without.(soon i find the only dyno in town... its hidden pretty well)

 

Mitsubishi does not make electric turbochargers. What you probably have is a cooling fan designed for fuel injectors/injector resistors. Or a heater blower fan from some truck.

Either way, it is doing nothing. I'd love to see a picture of the thing though.

 

Something like this: https://www.rx7club.com/showthread.p...electric+turbo

 

wow mine runs 250 feet per min at only 2.2amps nothing more nothing less. maybe it has leaned me out just a lilttle but hey wat ever works right. ill be posting pictures soon of my project 84 300zx and will post one of the turbo. it runs off my rpm activated switch. pops on with my air pump(for ports). honestly looks nothing like the pulley looking one on that forum but still same basic principle.

 

This is the new electric turbo. sorry cant get yea a inside pic but there it is..

 

And what you have there is a fan. If anything, it's restricting the air flowing into the engine. The fact that it's made of plastic, and says "Turbo 3000" on it is a dead give-away. If you didn't buy it off ebay, someone else did. You really should not waste any more time with that thing, and start looking into real turbochargers.
