Dyno & Bench Racing Forum - another lame lq4 thread (in rx7 though! :D)

Hey guys, just bought an LQ4 swapped FC rx7 (87)

4l60e with the corvette stator, "the beast" shift kit and a 2200 stall...

Car is a turbo 2 with the sweet IRS LSD differential and 4.10s..


The engine has an ls6 intake and injectors.. 28 lb injectors? I think ls6 tbody..

2.5 inch exhaust with an x pipe and flowmasters (super 40s I think..)

Anyhow, I'm wondering since I dont' think I can run headers with this setup (they only seem to make headers for t56 cars) and with a smaller stall....

I wonder what kind of power I'm looking at with a tune?

**Edit, The car is running on 1998 camaro ls1 electronics.. I assume with the auto computer, this thing is huge! haha...

btw I have the hptuners vcmi or whatever it's called... the VATS, 2nd set of o2's are disabled and a bunch of other stuff.. )

The car is pretty damn fast at the moment, obviously, it's so light, LOL...

A friend has a medium sized cam but I'm wondering if I should upgrade the convertor before upgrading the cam or anything else..

Seems that everyone says 9.4:1 is a brutal compression ratio, what's this thing like with say 91 octane? is it safe around 10.5:1 or so?

How can I tell which TBODY and MAF I have? Are these limiting factors?

Any advice would be great, looking for the experts to chew me to bits, I searched quite a bit but can't seem to find exactly what I'm looking for.

Thanks!

u wont find any info about this over here.
but the lq4 is plenty powerful even with 9.4:1 scr. if your on stock cam, it will run a lil better with 89 octane. before u upgrade to cam, mill the heads for more compression or those big cams will lose power and tq under 4k rpm
if you stay on the stock compression ratio.
a better matched tq conv. like a 4k will wake up the car even more
mill the heads, thinner gasket, with ls6 cam, 4k stall, it will make for a night and day difference in acceleration, and the engine will be over 400bhp even with stock exhaust manifolds.

post more in the swaps forum. alot more replies over there

wow 4k rpm!?!?!? CRAZY ... i think the first step is going to be some sticky tires i blow the tires completely away at the moment from a stand still or if i dare put it up on the convertor at a stop LOL

thanks man, you're a life saver.. .i'll check tha tout
