Another R32 Money Pit

[Deano 1]

awesome man, ill be watching this

[battery]

interested to see how u go with that turbo i have been thinking about using the same one except low mounted on the stock manifold with a spacer/wastegate adaptor. but im thinking its gonna be restricted greatly by the manifold so i might just use their td06L2 with the 10cm rear.....

Exactly what my plan was until the turbo arrived... The front compressor housing is big (like a Garrett 0.7) and it was going to need like a 30mm spacer!

In the end I figured getting a spacer, another gasket, the exhaust housing welded etc was all going to be a headf**k (and decent cost) so I just ended up going a 6boost. Plus as you said the standard manifold was probably going to be a restriction at the power I'm trying to make.

The TD06L2 10cm also seems like a good option, I think the only difference being it is water cooled as well. Plus I have read that the 20g front wheel really runs out of puff at about 270rwkw

PS. Shouldn't have to wait long, car is going to be on the dyno this week (fingers crossed maybe even tonight)

Looks pretty good

Turbo looks good, Simon & Battery, the T67-25G and the TD06-20gL2 share the same turbine wheel and housing, the difference is the T67 uses a TD07S comp wheel and housing, which is also the same as the TD06-25G

[battery]

the adaptor i have is similar to this...

but yeh that t67 is pretty big ill be putting it into a 33 which i think will give me a little more room?

i'd love a 6 boost but im not really interested in paying the $1300 to get one!!

there seem to be a few guys pushing 260-270kw with the td06L2 8cm rear on sr20/rb20, so i think it may be possible to get to 280kw with the 10cm rear...

Keep looking around for a 2nd hand 6-boosy, I sold mine which was a twin scroll T4 for $500.

yeh i could stomach $500..

i think ill wait for simons result before i decide on anything, should be interesting...

what are the lines and fittings included in the kit like?

Oil feed is good (you need a fitting to go into the block), oil drain was a tad short so we are replacing with a braided line (better to be safe with heat + oil = fire)

I'm crossing fingers for results tonight... All we have to do is the oil drain, dump pipe and gate screamer pipe!

[SimonR32]

So close now...

Its funny seeing RB20 cam covers with the 25 timing belt cover.

Nice and neat too

[Roy]

SO, sick of toasting RB25 boxes behind a 20 so you throw a more powerful RB25 engine in front of the same sort of gearbox? Any excuse to lose the RB20 ay?

Interesting to see how it goes...you guys are just rough bastards. My car will hit 200,000kms this weekend at Winton and its still the original gearbox !

Don't you like my reasoning haha

Roy I love my RB20's and always will, but times are changing and I just couldn't see a way to keep up with the Jones without going more capacity

Got some results via text message, made another 100hp will post graphs soon

[Roy]

Another 100hp? Eek.

I figure my car and engne still have some speed in it so will be fun trying to get a bt more from it. But concede that the money I am spending fiddling trying to find the sweet spot doesnt not make much sense.

[SimonR32]

Actually ended up going 517rwhp (386rwkw) without correction...

So that is a 127hp more than the RB20, plus it's 700rpm quicker to come on boost and nearly doubles torque between 3000rpm-5000rpm

Does nothing but burnouts in pretty much all gears

[Roy]

What fuel? Throw some decent suspension and tyres at it now.

I know what turbo my 1jz is going to get now!!@!@!@!@1

I've got all adjustable links but my rear shocks are not the best... I have a pair of RE55's at home but don't want to lap them on the street so the plan is to get some KU36 and see how they grip.

I'll post the graph up pretty soon but it makes 15psi at 4000rpm which is a bit later than STATUS results but it may be because of the fuel (which seems to make turbos laggier on most cars) or because the turbo was literary brand new when it drove on the dyno with no run in.

Still massively impressed with the results, the car feels about on par for pace as my old GTR which makes for a scary RWD

Boost & Power

RB20 (dark lines) VS RB25 (light lines) Torque and Power

[Roy]

How much ignition are you running in your RB20 tune? It looks one the boost hits there isnt really much gained hp wise from more revs and the torque seems to die off real quickly.

The RB25 setup with the T67 looks the goods!
