Simple Turbo Motor Setup.

[flhmfd]

i've been on here for a while now and well the car is becoming a little boring to drive. i've browsed the FI thread a little bit recently and just thought about boostin a non-magnum SOHC motor for my r/t. mainly because i've heard that turbo magnum are somewhat of a PIA due to the timing.

question is could i reliably boost a non magnum motor with a basic SRT4 turbo kit to make around 200 whp. and at what boost would i need to run roughly to get this.

im not really looking to get into fuel managment and stuff, shooting to use the stock ECU (not an NGC), possible?

i was recently layed off with pay and am getting bored as shit, need something to occupy my time...

thoughts?

reliably boost

Those 2 shouldn't go together lol. Theres nothing wrong with the R/T computer, you just need to know what you are doing. You need to get into fuel management if you plan on going over 1 psi. You also need to trick the computer so it doesn't see positive pressure. The stock ecu 'works' but there are some down falls, the main one being open/closed loop transition. Other smaller problems are the knock sensor pulling timing weird, the CEL's, and just the inconsistances of using a stock computer with a rrfpr. I guess to answer your question, if there was an easy and cheap way to make 200 whp with a turbo, everyone would be doing it. Only the determined make it work, I am sure anyone who has turbo'ed there car for a while will say that. Also, if you do turbo your car with the mag motor making 200whp is not a big deal on the stock block with a good tune and the right supporting mods.

i was reading about your set up, thanks for chiming in...i'll look into things a little more in depth.

Kevin,

i was reading about your car. sick set-up man, and uber clean. that's the perfect look, props.

on another note, the megasquirt allows you to solve the problem of advanced timing on your magnum motor, correct (because iirc, it controls a lot of the stock functions including ignition timing and fuel, idler control, etc etc etc)? how do you find megasquirt compared to other engine management systems? i am looking into that unit for the ease of use (lap top compatible) and the variety of features contained within that single unit, rather than having a whole bunch of seperate ones for my set-up being planned this summer. your thoughts are greatly appreciated.

p.s, i will be running a built motor with low comp. pistons, forged rods, and turbo cam along with the supporting valve springs, retainers etc.

Thanks! MS has more features than most people end up using, pretty easy to tune, and is super super cheap for what you get. If you get MS running on your car and all the bugs worked out, its really a great system compared to anything else available for our cars. It can control both spark and fuel, so that takes alot of unnecessary systems out of your car. The downside is you need to be in control of MS, not MS in control of you. That means tons and tons of reading until you understand everything before you even touch it. MS is really picky with alot of things regarding firmware and sequences that can be over looked. I hate computers and crap but I got the hang of it.

i always like a good challenge haha. so with m/s i guess the factory ecm problems mentioned previous in the post (closed vs open loop etc) do not apply when using m/s. plus, i will be doing the install/tuning in conjunction with a local shop, so wiring and tuning/everything to do with m/s shouldn't be too much of a problem since they have experience. thanks for the input.
