Thread: L67 engine swap comin this weekend!!

I am finally going to do my L67 engine swap in my 99 GT this weekend. I will post pics of it next week but here is the list of mods. L67 w 75000 miles, all new gaskets, 180 t stat, 10.3 mm wires, al 104s, ported and polished Supercharger with slits filled, Tog headers with 3" catless down pipe, 3.4 mps, intense pcm, slp ram air intake and sd hood, arp head studs, speed daddy functional gauge fuel pressure regulator, 42.5 lb lucas injectors and thats all I can remember for now but I will get pics up this weekend.

You should take a lot of pictures and make a nice write up.

2 things...

1...got a tuner?

Second of all...ewwwto the slits filled in the blower...good luck with that.

I dont have a tuner it has been tuned by intense for all of my mods and 3.29 gears. The slits in the blower are just gonna make her whine like crazy but in the event that I dont like it I am adding a gen V blower. I am going to take alot of pics for future swappers.

hopefully the ported genIII will do the trick for now. I have to get this one put in to see how i like it the gen v may go in with roller rockers at a later date.

I meant for the fact I hope they are secured well. I've seen some nasty situations of non-intercooled folks where the silts broke out of the blower case and were sucked down into the engine...and poof.

why are u running 42#'s?

over the counter pcms suck, get a tuner/

yeah we will find out because I will be drivin it back and forth to stl 3 times a week

Well we are digging in tommorow to try to get the swap knocked out. I am going to take a ton of pics and try to get it running tommorow.

it is a daily driver and the increased compression on a bottom end with 150000 miles scared me. I got a really good deal on an l67 from kejross with about 75000 miles on it. I got a ported blower headers intense pcm 42.5 injectors 3.4 mps all the good gaskets 10.3 mm plug wires arp studs and got to put the engine together on a stand and take my time. Plus I sold the l36 to finance part of the operation!

you deffinitly dont need the injectors yet, you havent even upgraded your throttle body, or valve train. do that before you worry about the injectors. you should stick with stock size injectors for now. and if the head gaskets arent blown you dont need to do them, these heads are good.

well guys I went and started today but I forgot my camera and I also forgot to take the part of the wiring harness off the motor that goes to the coil and crank sensor so I gotta find one tommorow somehow. Also it appears that there is no way to plug the BBV valve in off of my wiring harness and the low oil sensor in the oil pan seems to be different from 98 - 99 any advice on these issues would be greatly appreciated

Get an oil pressure gauge. That'll solve it.

did you get an l67 harness? if not the map sensor will be different too.

oil pressure sensor, you could buy a new one that matches the year of the harness. they are $10 at AZ

I found a map sensor on a buick riviera with an l67but the wiring harness is hacked and I ordered the l67 swap kit from zzp. as for the oil sensor I am gonna just get a new one for my current harness. I also found the piece of the harness I need for the ignition but its in a wrecked bonneville so I am going to try and get it out this afternoon.

Well its officially a gtp with 3.29 gears ported blower headers and all the other stuff I mentioned. I dont have map sensor or the bbv valve hooked up yet but I have that stuff coming from zzp this week and I am going to finish it up next sat. My SD hood should be here monday and I am taking it in to the body shop to get it painted detailed and badged next week. Even though my car isnt a true GTX I got the badges spoiler and a set of the wheels that I am having striped and powder coated chrome as we speak I included a pic of those as well.
