Quick and easy V8 swap ? (2.3 to 5.0) Reply #15 – December 06, 2006, 02:39:33 PM LOL... I had just put new Konis on the car that morning.. I was on my 'test drive' when I took the picture. It has settled down some, but it certainly isn't a low car.. This is pretty much the stock stance.. These stock 15" rims don't do anything to help either~ Quote Selected

Are you saying it doesn't matter what engine I start with since once it's rebuilt it will be 'like new' anyways?Yes...Honestly unless you get something that was horribly abused, it doesn't make a difference. Especially if you're planning to have the engine bored and install new pistons.I pulled an engine from an '84 Turbo Coupe a couple years back to rebuild. It was in a car that had been abandoned (got it from a towing company), had a questionable usage/maintenance history (looked like it had been jumped into a gravel pile and gone over with a baseball bat), and had 145K on it. I tore the engine down and had it checked out. The head wasn't cracked, the mains didn't need align honed, hell the crank didn't even need turned (only had the journals polished). The only bad part of the engine was some scratches in the cylinder walls, I couldn't afford to have the block bored & buy new pistons so I just had it honed and reused the stock pistons. I now have 20K on the engine, it runs great and I really have no complaints with it whatsoever. I only wish I woulda been able to afford new pistons because I get some blowby due to the scratches in the cylinder walls. Quote Selected

Quick and easy V8 swap ? (2.3 to 5.0) Reply #18 – January 03, 2007, 09:14:55 PM As far as the fuel question goes, I found out how to use the factory in tank 40 psi pump and get 6.5 psi at the carb. I got this tip 2 years ago off a link at toohighpsi.com and it worked great! I put a "t" fitting inline connecting the high pressure feed to the return line. The 40 psi pump runs full time in a "runaround" mode as normal but because the return line is smaller to the tank than the feed line to the engine, it produces a natural restiction (which produces backpressure) that just so happens to be 6 psi at idle and 6.5 psi when the rpms come up. I have run this setup for over a year and bracket race this car (my 84 non-h.o) with a 88 Turbo Coupe tank. I do not know how this would work on an engine making more than 250 hp but I am pleased with the results so far. All the fittings at the hardware store cost me $ 18.00 I'll try to get photos of my setup on the '84 and post them. Quote Selected

The FPR's for carbs are out there also.I love that whole loop back thing in order to get carb psi,, although i think its just the restriction size that accounts for the redused psi like you said. It kinda acts like a large leak in the fuel system and the leak goes to the carb. Ill assume you dont run a carb return line eh?and for fuel injected folks who want an acspoogeulator like what GM provides as oem,,, which smooths out fuel delivery, here is a home grown version of what can be done.

Quick and easy V8 swap ? (2.3 to 5.0) Reply #21 – January 04, 2007, 10:27:19 AM No I do not use any return line from the carb because it deadheads at a perfect 6.5 psi. I have no idea what the long term effects are with this setup because it is too early to tell. Any thoughts? Quote Selected
Quick and easy V8 swap ? (2.3 to 5.0) Reply #22 – January 04, 2007, 12:12:23 PM You'll have a problem using the T/C K-member. The way the 2.3L mounts on the K-member is different than a V8. That IMHO is about the only major problem you'd have. Look at your k-member, then go to a salvage yard and look at a V8 k-member and compare the mount pads. You could also look at some V8 mounts from a parts store and then look at yours. I lucked out as the MKVIII DOHC mounts the same way as the old 2.3L. Quote Selected

Quick and easy V8 swap ? (2.3 to 5.0) Reply #25 – January 05, 2007, 11:57:42 AM I had an 85' elan with a 5.0 and I have an 86' T/C. The k-members were different where and how the motor mounts bolted on. My 86' T/C has a pad where the mount slips over and the bolt goes through front to back. The 85' elan had mounting pads like a mustang where the bolt that goes from the mount through the mounting pad. I had bought the elan to swap the engine into my T/C but at the time I only had a gravel driveway and not all the tools to change k-members. I put the 5.0 back into the elan and gave it to my would-be exgirlfriend. Maybe I had an odd ball car. Quote Selected

Maybe I had an odd ball car.That was a MY change, not an engine thing.In 86 they changed to the different style mounts across the board...not just the TC. All you needed was 86-88 5.0 mounts.....simple as that. No need to change K-members. Until recently though, there were no aftermarket motor mount options for the 86-88 5.0 cars.... Quote Selected
Quick and easy V8 swap ? (2.3 to 5.0) Reply #28 – January 05, 2007, 01:50:38 PM No, it wasn't a MY change. Yes, I was going to change the 2 engines but because the K-member/motor mount issue, I didn't go through with it as I said before, I didn't have the tools/time to change the K-members.But the two definately were different! But what do I know. Just a back yard idiot I guess. Quote Selected
Quick and easy V8 swap ? (2.3 to 5.0) Reply #29 – January 05, 2007, 02:12:21 PM Uh...yes it was a model year change.... ALL of the 86's used the changed K-member with the pads welded to the K-member instead of the angled mounts like the 83-85s...You could have put the 85 5.0 in the 86TC with 86-88 5.0 motor mounts. No need to change the K-member....But what do I know? Just a backyard idiot I guess.... Quote Selected
