Gerg_R31's N/a Rb26/30De

[fatz]

yea just had a spare on lieing around

in gtr's its twin plate or nothing

[mico]

this is awesome mate, i wanna hear it wot !!!

[FordyR31]

Sucks with the clutch mang. I have had an excedy cushioned button in mine since the swap. No issues whatsoever. Must be a hit and miss dealio. I wanted to organise a night at the drags soon but guess u wont be heading out. an always come watch the rest of us have fun.

[Gerg_R31]

Yeah these things can't be rushed so when i do hit the tracks my patience will pay off

once xmas has passed ill come down to WSID to watch, kinda here at the rodders life thing now at WSID working and choking on methanol fumes

[Gerg_R31]

VL box and custom clutch on its way, got new plates will upload pics soon

and to the guy in the van this morning, sorry im not much of a morning person but yeah i work at Duncan foster (link below) pm me for details on what you want to do to your r32

[Gerg_R31]

Got Vl box, single piece tail shaft, and as of this morning no clutch grr probably shouldn't have gone for a drive through national park on the weekend

[Char]

very cool build mate, will you go turbo when off p's?

[Gerg_R31]

Lol been off P's for about 2 years which was when this motor went in

[Simon-S14]

just read the whole thread. props for doing what many people have talked about and never done. nicely put together engine. If it were me going for power and torque i probably would have made the CR around 11.5:1 and tuned it for E85.. would have been nuts then

[Gerg_R31]

Ty

Yeah i was thinking about the e85 but no one near me sells it, pros of the haltech is i can get it tuned to the e85 later

[jamie curran]

^^ haha yeah u just have to buy 2 more 600hp fuel pumps

[Wayne.]

any videos of this thing ?

[Rolls]

yeah just read the thread lol

[Gerg_R31]

Yeah need to get in car videos/ bumper videos sometime soon

ok well old gear box is out, clutch plate 4/5 still good,

pressure plate fingers are badly worn,

the thrust bearing (appears to be the culprit) is fairly chewed out on the inner surface that connects to the input shaft. It shows signs of metal rubbing on metal and seizing on the input shaft

Single piece tail shaft & MX7 box next to old bits

[Gerg_R31]

Nothing new, still waiting on clutch to turn up

I decided to do some maths

.........RB30/20........MX7/VLT.....Difference with 3.89:1 diff............Difference with 4.11:1 diff (coming soon)

1st.....3.321:1.........3.580:1.........7.3% Increase in acceleration........12.5% Increase in acceleration

2nd....1.901:1.........2.077:1.........8.5% Increase in acceleration........13.8% Increase in acceleration

3rd.....1.308:1.........1.369:1.........4% Increase in acceleration.............9.3% Increase in acceleration

4th.....1.000:1.........1.000:1.........--------------------------------------..............5.3% Increase in acceleration

5th.....0.759:1.........0.759:1.........1% Decrease in aceeleration............4.3% Increase in acceleration

[MBS206]

You are bored aren't you?

Do you want me to give you an LS1 to pull down, check up on and put back together?

You can bump the compression a little bit if you want...

This is a bit misleading because the gear will be over quicker, hence you'll be in the taller gear sooner. If you were to graph the acceleration of both diffs overlapping you'd see on average the acceleration isn't improved greatly when looking at a large spread of kph. In just first gear etc it will be a large increase though.

[Gerg_R31]

Yup i was, speak to sams performance, he builds some really high powered LS motors bit expect atleast an 18 month long cue

Yeah, the 4.11 diff will only give a 5.3% increase on paper compared to the 3.89, but looks like a bigger increase if you add the vlt ratio and compare it to the standard gears and 3.89 diff

And yeah taller gears = more acceleration and less top speed

but this is all on paper, will chuck it on a dyno afterwards to see what difference the 4.11 made on acceleration

[Gerg_R31]

flywheel before being ground

Flywheel after its been ground and ready for balancing

flywheel being spun up to check for balancing

New cushion button clutch plate and modified pressure plate

Blancing Pressure Plate

Spinning up pressure plate

thats all for now

[jamie curran]

nice man
