Turbo Thread

[rustywagoneersdotcom]

I have done 2 customer cars with a stock ECU, small T-3, Ebay eclipse or volvo intercooler, bleed/check valve in the MAP line, and Rising Rate Regulator (aka, FMU, FPR, etc).

One on a toyota celica, one on a little honda. Both ran well. Not gonna win formula drift, or any national notoriety, but they were WAY faster than all their buddies. Even the ones with rich daddy and fancy kit parts. IIRC, the honda was a CRX with a 1.8 integra motor??? He got a manifold for a T-3 off Ebay, I put together the T-3 and got him running. Ran 11.80 if I remmeber right.

Anyway, point being, though the Rising Rate Reg with a stock ECU + bigger injectors + boost bleed for the MAP may not be the PERFECT way to do it. But we don't all need datalogging and we arent trying to nail down our clutch slippage values.

The story goes that Russian engineers often quoted Voltaire - 'The best is the enemy of the good'

So in the meantime. Looks like a FMU to start with to keep cost down.

Next question, How in the Hell do I trick the ECM to retard timing when boost is applied?

MSD boost timing master. Easily adapted to any ecm controlled electronic distributor, and it senses boost. It also has a knob for dialing back the timing- so many degrees per pound of boost. You will also need a strong ignition, 1-2 steps colder plug, and narrow the gaps a little prevent spark blow out.

Heres the one I built for my 4.5l 24v I6 in my 80 series cruiser. Has a t4 from a ford d-truck. A 350 swap would be a downgrade at this point.

I read up to page 4. Great build. Any suggestions for me?

My main concerns is:
1. spark advance under boost
2. MAP sensor using a checkvalve under boost
3. Supplying enough fuel and what octane to run?
a. debating on installing a 7th injector with an inline "trigger" to supply a little extra fuel on boost only. ATP turbo has all the parts to do this properly.

I will only run 5-6 PSI boost at the start.

Should I wrap my Piping to the turbo? Is running an 0-2 sensor before the compressor a good idea?

My turbo will be a remote mount on the passenger side. I will fab up some support braces to the engine to help hold the weight. I plan on 2.5 inch exhaust from the compressor to a new High flow CAT into a new 2 chamber muffler then a straight dump after the muffler. All of this will be 2.5 inch. Maybe bigger if you all suggest it to be.

This project will kick off after I get back from working (playing) at KOH. I will be working a checkpoint and I want my rig for Sats trail run. then after that, the heep goes under the knife.

95% of those who talk turbo never do it. a late model engine like that in a jeep will usually support 5psi without any engine management so no need for 7th injectors, fmu's, seperate computers, etc. Just build it. use a similar turbo as others have done. then take it to a dyno and run the A/F ratio out the tailpipe. or spend $300 and buy a wideband meter and know for sure. Fortunatly others have a blown jeep motors so the research is done

[jpfrk2001]

then im that 5%. Already got the turbo assembly with internal wastegate and Blow off valve payed for in the mail. Here is the link:

Can't order my mount flange till I get this thing. Then i will order the pre-mandrel bent pieces of different sizes.I will order the rest of the parts(EGT Guage, BOV weld on adapter, FMU, etch) after I get just the mounting and exhaust plumbing done.

I am in no way going to rush this. I hope to be running this 2 months from the start of the job if im lucky.

you sound commited. cant wait to see it
