LS1 conversion...

[coachreed]

I was just wondering... which do you think would be easier? Putting an LS1 into a VX or putting an LS1 into a Mazda RX-7? Would you agree that the engine compartment of a VX would have more space than an RX-7? Just to let some of the nay-sayers see how compant an LS1 really is... please check out this picture... this is a conversion that I found on LS1Tech.com's conversion board... I will be spending some serious time here talking... but check it out... IMO, if it will fit in an RX-7 it WILL fit in a VX...

(not sure if his server will allow remote linking... if not, I'll copy it to my gallery...)

Anyway... I'm off to read some boards... make this happen... its no longer JUST because I want it... IT'S because there are some nay-sayers out there who say it won't fit... where there's a will there's a way... TTFN!

I don't think it was a question between 3rd or 2nd gen RX-7's... just whether it would be easier to install in an RX-7 or a VX.

If it came to a 3rd gen, the rotory engine is definitely too sweet to take out. It's definitely much more maintenance than a regular V, but rotories are just sweet!

Haha - 18 times the speed of light, eh? Now THAT is FAST! Of course, 18 times the speed of sound isn't half bad either.

i think teh vx should be easier...seeing how the vx has pistons and so does teh ls1:D

Ya know, I've seen that picture about 100 times and I hadn't realized the typo... ;eekb; 18 times the speed of light?! DAYUM! ;eekb;... WOW!

Yeah, the point of this thread is that even though it is NOT a third gen... and there is a decent amount of space in the 2nd gen RX7... that LS1 motor is compact... and with the complexity of the Isuzu motor... it makes it larger than it has to be. Yeah, the block might be small... but those heads are tall and wide.

Anyway, TTYL!

A person on the site below desided to go with a L98 5.7 V8 instead of the LT1 in his second gen RX-7.

Q. I have a 1st gen RX-7 and would like information on a V8 conversion, using a Chevy 350.

A. You will need a hood with a scoop, or a hood scoop.
We recommend changing the front coil springs to compensate for the added engine weight. We also install gas shock inserts at the same time, for all our conversions. We use a Chevy transmission, and we recommend changing the rear axle to a Chevy rear axle, 2.73 or 3.08 ratio. This will give you excellent gas mileage and good performance, without over-revving the engine at highway speeds.
The rotary rear axle would be the weakest link, and at 70 mph with a 3.90 or 4.10 Mazda rear axle, the engine would be revving at 4000 rpm, which is too high for sustained driving.

Here is a list of the parts we use for the conversion:

Motor Mount Kit, including Distributor cutaway cap for firewall $400
GM Rear Axle $1150
10' #1 battery cable $50
Disconnect switch (highly recommended for security) $60
Custom drive shaft $250
Custom 4-core Radiator $300
Custom Rad Saddles, top and bottom for V-8 rad $75
Rad hoses (molded) with T-section filler cap $132
Electric fan, 16", curved blade, 2300 cfm air flow $200
Fan Sensor $25
Fan Relay $35
225 lb 10" Coil springs $250
Gas inserts $130
Exhaust $600-800
Hood, fiberglass inside and out with factory hinges and latch, primed $650
OR Hood scoop, primed $175
Here is a brief outline of some of the labour required:
Pull motor, transmission and rear axle
Modify struts
Remove seats & carpet to bolt in tranny crossmember retaining plates
Install engine & tranny
Install transmission cooler
Install rad, fan & T fitting
Hook up electrical
Install rear axle
Move battery to back
