N/A'ing my Turbo; LS1 conversion project

[flash968]

i wasn't trying to sidetrack the thread, left out all the details, and was merely pointing out that it is easy to spend that much money.

but, to answer the questions asked:

first off, it's about 100lbs heavier than the 968 engine, even with the bang zoom all aluminum motor he used, not 40 or 50. you have to factor in all the other stuff that goes with it, not just the engine. not the end of the world, but definitely threw off the balance.

as for driving poorly, everything about the way the car drove was a mess. tons of power in a straight line, but useless. the chassis couldn't handle it. everything that made the 968 what makes it what it is, was lost. it felt like an old vette.

the hydroboost system SUCKS!. you have no sense of the car stopping.

the engine has too much torque for the torque tube assembly. you can feel the shaft flex. really nasty feeling, but you wouldn't know it unless you were familiar with what it is supposed to feel like.

the clutch was incredibly insensitive, and you couldn't use first gear at all (and he was using the turbo box). the chatter was horrible. he used the bang zoom stuff too.

basically it spent every dime to do it right, took it to the leading expert in the country on these conversions, and still ended up with a bucket of bolts.

i now return you to hopefully what will be a better build, if only by avoiding some of the problems of somebody else

ugh

Please just stop posting in this thread. After years of reading your posts on RL, Pelican and whats left of the 968 forum, i have zero interest in any of your input.

You seem to have one opinion on the LS swap, so we get the point. Yet you cant offer any details whatsoever on this car you drove other than how ****ty it was. Feel free to start another thread where you can discuss why an engine swap shouldnt be done.

I sent the thread about the charcoal canister to the shop working on the car, it looks really easy to hookup. The two rear most coil packs were relocated, he mounted them a bit higher up on the valve cover instead of a more remote setup like the other guys have done. I didnt look too closely at it, but it looks a little bit close to the nitrogen 'canister' on the hydroboost unit. So they may need to be moved further away depending how much engine movement there is. I dont expect there to be much though with the engine mounts.. but then again this thing does put out alot of torque!

The radiator from Renegade should have shipped last week, so work on the intake setup can start once that comes in.

The shop said they finished up the fuel lines, wiring on the engine side, battery cables and also completed hooking up the brake lines to the Ford master cylinder.

Unfortunately i am offshore for a few weeks, but looking forward to seeing the progress when i get back!

This is looking awesome. Hoping for a video when it's running! I'm planning one of these swaps as well, already have a shell of a car that I'll be using and decided on an LS1 engine. I'm collecting parts over the winter and will hopefully start building it with the help of some friends in the spring. I may message you with questions as my project progresses.

John,

If you pass the White Plains area I would like to take a look at the car. Or maybe I go meet you, really interested on the whole setup.

[running_cold924]

Keep your head up John, I've read a lot of your posts over the years too and realize you get into something and you DO get things done. Correctly.

I'm still tuned in...

There is an ignore button. Profile, user lists, add to ignore list. Effective.

Great work by the way. I used to have half baked rh 944 lt1. Brakes were higher pivot point. Sucked. Brothers stock mustang gt 1998 brakes felt just ok. Not sure what the solution is, but read all of tony g posts. He races so much, his suggestions have to work. I wish I could have that much track time....

[Techno Duck]

Here is some more progress over the past month. The radiator took a bit longer to arrive than expected so that held up a few things. But the wait was worth it i think. Shop said it fit well and it made the hose routing much easier.

Just a few more things left to finish, hopefully it will be ready to start before i leave again in a few weeks .

To be finished..

-Wire in fuse block for the PSI engine harness, tach signal, VSS..etc.
-C6 vette intake setup
-Hoses for coolant expansion tank
-Power steering lines
-Oil lines
-Exhaust from headers to cat-back
-Clutch master cylinder hookup, just waiting on 1 fitting so we can connect AN to the quick disconnect on the throwout bearing

I hope to have the car back by the end of the year, so i can spend the rest of the winter working out all the bugs. By spring time id like to have it mostly sorted out. Your more than welcome to check the car out whenever.

Excellent work Jon, that engine looks like it grew there. Beautiful

Its freaken loud! 4" all the way back from the long tubes with a Magnaflow muffler. I may have to get something more quiet.. but for now i can live with it!

The only thing left to finish is the intake. Getting everything under the nose panel (in particular the MAF) has been a pain due to the clearance between the radiator and hood. Just waiting on a filter which should be here monday (i love Amazon Prime!).



The rear section was off so a v-band could be installed to make removal easier. Everything fits amazingly well.



Hope to be able to bring the car over to the other shop for the alignment next week. A big hopeful is to have the car home by the 2nd week of January. Then i can start playing around with it

I sat in the car for the first time in a while today also. Felt a bit alien considering ive been driving my pickup and a E36. Pedal feel on the brakes was good, though the clutch will need some adjustment made. The pedal was surprisingly pretty light which i wasnt expecting. It was a bit spongy and the travel on the pedal was a little short. Needs to be bled again and hopefully can adjust the linkage / push rods enough to get the travel to my liking.

sounds amazing!

strong work!

[james6speed]

Really nice work man, I wish I was that inclined to do a build like that.

[Techno Duck]

Everything is done! Just cleaning up the engine harness wiring under the dash and doing some long overdue rust cleanup on the battery tray.

Fantastic!

Jon,

You have help me a few times. I enjoy and honor your ability to share your knowledge and respect many of us who contribute to this board. I admire your attention to detail and doing it right.

I hope the car meets every expectation you planned. And if it doesn't, I know you will analyze the problem and fix it - it is the mark of a good engineer and craftsman. I admire your work and passion.

Good luck with your new ride. You inspire me and I hope many others.

All the best Jon!

That is some serious 944-porn. Incredible work. Just beautiful.

[Techno Duck]

Put about 9 miles on her earlier and filled up with gas for the first time in 2 years.

Looking forward to the weekend .

Absolutely gorgeous - What of the handling with the NA motor in there ? Please let us know how the handling feels when you have a chance ...

.....Ricers beware.....
