My 944 1uz-fe V8 swap
- Thread starter Eldavo
- Start date
I have been in the motor trade all my life and for the last 10+ years have been running a successful Toyota Mr2 engine conversion garage www.woodsport.org , i've carried out literally
hundreds of Toyota and Lexus based engine conversions in my time, and even dabbled with the Lotus Elise installing a Camry V6 into that.
Anyway i digress, i have owned my 944 for several years, she is a basic 2.5 NA and i really enoyed it until this happened.... a bus decided to not want to take a corner properly, locked up and took me clean out.
So she has been off the road for 18 months now while i fight this company to admit wrong doing.
Recently i have had the urge to bring her back to her former glory and beyond, being an engine conversion specialist means i have all the tools and equipment (and a fair whack of knowledge) to make just about any engine
swap a reality, so it made sense to me to put a V8 in.
Now i have spent over a year researching and even parts buying, originally the plan was to use the Audi S8 motor, the AHC variant, in keeping with the Porsche heritage, i bought an engine, a 924 bellhosuing and an Audi V6
spacer plate to go between the 924 and AHC engine. We had even got as far as designing a new lower sump pan.
The 924 BH on the AHC, you can see it only picked up on 3 bolt holes...
Using the V6 spacer it gave a lot more attachment points....
Working with a friend of mine in the US we quickly discovered how insanely big the AHC is in the 944 bay....
We did get it sitting pretty....
But with serious sump pan and oil pump clearance issues to the rack....
We did a new oil pan in solidworks....
From there things went downhill, other stuff proved to be so difficult to get around we binned the Audi V8 route. So as you can see we've given this some serious thought.
I found a few threads showing a guy had already put a 1uz into a 944, and began researching that route, the 1uz is a monster and can be tuned to silly levels with bombproof internals.
Last week i bought a complete 1uz and an adapter plate from XSchop in the US to mate it all to the 944 torque tube...
This uses the T56 clutch slave....
I will be using a modified Camry Fidanza flywheel with its ring gear reversed and an Mr2 turbo clutch pressure plate, an Audi V6 240mm 23 spline disc completes the drivetrain.
The car itself has had its 2.5 removed, bay gutted, cleaned and ready for hotwork.
Ok so as part of this swap the 944 brake servo gets in the way, and has to go, now some 944 V8 swappers just mount their master cylinder unassisted onto the firewall as a solution, but i want assisted brakes on this thing.
After a few hours research i found i can use the BMW 635 hydroboost system, it basically uses the power steering pump supply to aid braking, quite clever.
So that is it bang up to date, i will update as i go. I realize putting a jap engine into a 944 may not be everyones cup of tea, but i yearn for a V8 944 and for me the 928 engine is just too heavy and expensive, so hopefully i won't piss
too many purists off with my build, thanks for having me.
