99RegalGS Posted May 8, 2004 Report Share Posted May 8, 2004 I'll do that just because it's a good idea to replace a 9 year old radiator with over 160K. The Rads they sell at NAPA have a bit more surface area than a stocker, too. Erring on the side of "more cooling" (esp. with a supercharger) is better than "more heat" for sure... I don't blame you for wanting a new radiator, wouldn't want to toast your engine. IIRC the stock radiator is a single core. I would check if you can get a 2 core radiator, or get your stock radiator recored with 2 cores. Another core will greatly help the radiator's ability to exchange heat.

rudefyet Posted May 30, 2004 Report Share Posted May 30, 2004 sweet....project L67 Bonneville is under way! Quote Link to comment Share on other sites More sharing options...
maybe2fast Posted February 3, 2005 Report Share Posted February 3, 2005 what about the LN3? so all I need is a top end of a early SC motor? Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted February 3, 2005 Report Share Posted February 3, 2005 Yes, but you will need L27 or L67 head's. The LN3 head's are slightly different. Quote Link to comment Share on other sites More sharing options...
maybe2fast Posted February 3, 2005 Report Share Posted February 3, 2005 if I get the new top end I should be able to use my exsisting wiring harness, and then use a custom chip to tell the PCM what to do with the boost right? Quote Link to comment Share on other sites More sharing options...
Curlybandit Posted March 10, 2005 Report Share Posted March 10, 2005 I know this thread has been kicking around for a while, but I just stumbled on it and I am VERY interested. I have a 1991 Series I and I've been looking into adding a SC, but I've been told that it isn't possible without a lot of work and headache. If what I'm reading is right, it should be a fairly straight forward job. So.... one more time, what do I need to turn my Series I N/A into an SC? Thanks.

99RegalGS Posted March 10, 2005 Report Share Posted March 10, 2005 At the minimum: L67 lower intake, S/C, Harmonic balancer, alternator and p/s pump mounts, additional idler pulleys for the s/c belt, maybe the fuel rail. Probably would be a good idea to get the L67 fuel injectors, bigger fuel pump, do something to beef up the transmission, get the L67 Memcal. Might be a couple more misc. Items.

Curlybandit Posted March 10, 2005 Report Share Posted March 10, 2005 So, for example, I can search for these parts off a 92/93 Bonneville SC since it's essentially the same engine right? Are there any recommendations that you can make regarding which would be the best models to use for my parts search? Thanks again.

Aaron Posted March 11, 2005 Report Share Posted March 11, 2005 Yes! Supercharge it with the M62, which is almost worse than the M90 Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted March 11, 2005 Report Share Posted March 11, 2005 I would try to find a 94,95 M62. They were much more efficient than the 92,93 versions. and Yes you can search for the S/C bonneville, S/C park Ave., and the 95 Riveria.

Curlybandit Posted March 11, 2005 Report Share Posted March 11, 2005 Thanks for the info. Let's see how far I actually get with it Quote Link to comment Share on other sites More sharing options...

Aaron Posted March 11, 2005 Report Share Posted March 11, 2005 I would try to find a 94,95 M62. They were much more efficient than the 92,93 versions. Wow, so maybe 35% Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted March 11, 2005 Report Share Posted March 11, 2005 lol, BETTER IS BETTER. and Acutally the 94,95 L67 got 20hp more than the 92,93 did with a smaller pulley. Quote Link to comment Share on other sites More sharing options...
Aaron Posted March 11, 2005 Report Share Posted March 11, 2005 So the blower wasn't more efiicient, just made more boost? Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted March 11, 2005 Report Share Posted March 11, 2005 noo. The 92,93 M62 had a smaller pulley. The 94,95 had a bigger pulley, yet made more boost. Quote Link to comment Share on other sites More sharing options...
bartonmd Posted March 11, 2005 Report Share Posted March 11, 2005 As a slightly off-topic post, I have an '87 Bonneville... I had debated turbocharging it when I was in college, but was too worried about the tranny (original Hydro. 440... gimme a W, gimme a E, gimme a A, gimme a K... what's that spell?? ASSTASTIC!!!) with it being my only car and shifting kindof funny as it was... but I was looking into it and found out that there was not really much difference between that engine and the engines found in the Grand Nationals... Both had 8.0:1 compression, and parts and bolt patterns looked identical... Appeared all it would take was some plumbing and an ECM from one of those cars... I gave up on the idea because my Bonne is an SE, so it has steel wheels, shitty brakes (I don't know that there was a "non-ass" brake option either, and brakes are important on a car that you're turboing), ass suspension, and that shitty tranny, but if I find an FE3 mid-late 80's 3.8 A-body, it's ON!

Curlybandit Posted March 12, 2005 Report Share Posted March 12, 2005 Will my 440T4 tranny be able to handle the increase in hp and torque? I thought about replacing it with a 4T60E but, I've read that the 4T60E is shifted electronicly using solenoids controlled by the ECM, and it won't work without computer control. It can only be used with an engine that was originally equipped with a 4T60E. So.... what are my options if the 440T4 can't handle the power? Thanks.
