well, i just got tpi, and im doing ne mods to it before i put it on my engine. I have a 355, mated up to a 700r4, the heads are nothing special, just old castiron heads, and mild (rv) cam.

im just wondering what i should do to the tpi setup before i put it on.? i have allready began porting the plenum, and i got injectors off of a vette, (24# i think). I am thinking of siamising the base, would this be a good idea. allso, will these changes require major prom reconfiguring. i dont have the necasary equipment to burn them yet, but i plan on getting it soon.

ne other suggestions. allso, could someone please help me with my wiring problem?, i posted it like last week and havent gotten an answer. i need to identify 4 wires, larger gauge on drivers side of harness, 3 red 1 purple. ne ideas? sorry for the long post. thanx in advance.

 

Hey,

For the wire identification you might have to get a repair manual that has the schematics in the back, that will show the different color wires, other than that I have no idea except just looking at my fuse box to see were they are. When do you plan on doing this?? I will also do some looking around to see if I can find any more info on this.

Someone has to know something on this board!!! Help :hail: lol

Later, Mike

P.S. tell me what you think of this!!!!

 

i like it, go for it. i think that hood is awsome on your car. i m not sure about mine though. i dont think it would look good in white.

 

Those 4 wires, most likely go like this.... the 1 purple is the 12v ignition power source from the key itself, to the starter. Most likely the other 3 red ones, are the main 12v sources to the ignition and fuse box itself. Are these 4 wires going in by the Master cylinder??? If so then this is what these are.

Siamesing and porting is going to help get the RPM's up a bit, but being that you have a cam and 24#injectors you should be looking into haveing the prom reprogrammed.

 

do you know where i could get one reprogrammed for fairly cheap, untill i get my own stuff. cause itll take me a while.

 

I don't myself no, but there are a few on here that are right into prom buring that may be able to help you out, don't worry they'll pop up here for yeah, but do a search on prom burning and it way lead you in the right direction.

 

As far as prom burning search through the archives here. As far as wiring check out this site as he some of the more popular wiring for the tpi system. http://chevythunder.com/

 

TPIS will burn proms also!!
