26/30 R34 Gtr **now With Results**

he wont, hes changed now, hes married now, he used to be cool way back when.

Small update to keep thread going.

Put car in air sussed out clearances and work out few other items.

Done one cycle of engine temp so far will do another 1 or 2 and then re torque head back down. Even with 1/2 grout filled block water temp sits nicely doesnt get hot, so promising signs it should cope in traffic.

Dump pipe needs 16mm added to it as it sits too low and back.

There is a fingers gap everywhere around sump and diff except 1 bolt which in pretty close but engine torques away so it should be right. Pretty happy about that.

Sorting out adapting the standard clutch cylinder just without clutch booster, making a plate and brace will post photos if it works out. Only have 90mm between firewall and hypertune so really narrows out options. Spent alot of time measuring various clutch cylinders from makers seeing where it leaves up......not very good position.

Getting there slowly dump pipe should be welded up in next 7 days.

We want to be able to move it under its own power by sunday. might be a stretch but something to work towards

The engine building was the easy bit this is the time we werent looking forward too.

As are we, Will be posting up videos, thoughts and results once start doing some kays and dyno time.

Very interested in seeing the difference between the old 2.7 9950rpm rev limit stroker engine and 3.0 (rev limit to be worked out on dyno).

Made a HUGE step forward tonight. the prototype bracket for mounting clutch master has worked and we have a full clutch working pedal. Now we just need to make a presentable bracket and rod and will post up how we did it for others who encounter the issue.

Small update

After a long month of sitting doing not much after a few hold ups, it has moved 10 meters under its own power, thats as far as it got.....the battery has packed it in and apparently quad plate clutches arent user friendly and wont start again. New battery time.

Plan is monday go for a short drive small load then onto hoist for final checks. After all clear its going for a highway run in/street check of tune.

Videos will follow. Cannot wait

[nick81xd]

Car has done just over 100klms on new engine and no real issue .

Valvetrain is a little bit noisier then we would of liked but you get the with solid buckets.

Car feels strong, wants to go, Alot more noticable torque over the 2.7 stroker engine. dont have to struggle to get the thing going off the line. Now able to cruise up a hill in 6th and not go back a gear. 30 bottom end worth it just in the respect.

Exhaust note pretty much the same for those wondering.

Thursday afternoon the sniffer is going in to check mixtures and then its fun time...loading some boost into it see what its capable off.

PICS:

Proof it left the shed

First wash in almost 6 months

Car is loving the new engine. Its so much easier to drive and more user friendly Tim (owner) is saying. Evident by the lack of throttle percentage being used.

Had the sniffer in the exhaust aswell. around town cruise its only a little bit rich but under full power its going to 10.1 afrs so heaps of power left in it. Goes in soon to get a tune done.

Tidying up engine bay now finish off a few bits and peices, then its ready to go to powerplay hopefully in january.

Took it out for a thrashing on the weekend and aside from banging limiter too quickly its awesome fun.

photos and videos

[tweety bird]

nice outcome, you must be really happy with it.

[NYTSKY]

Couldnt really tell from the incar but it looked like the gate cracked at 5500rpm???

When does it hit full boost?

[nick81xd]

gate cracks around 5400 full boost by 5700.

Its lazy atm due to a average tune, lots of fuel and a tame timing map. wont get much better though.

Old motor reved to 9980 so wasnt a issue of short powerband thats for sure

[GTRNUR]

Which version of T51 is it running?

SPL or KAI either way its still only 400 rpm off the T04Z/GTRS spool time on the typical RB30/26 hybrids. Not bad at all considering.

Sounds great in the videos too.

[mico]

well done mate, love the clip with the hazards on.

[nick81xd]

Its a KAI version. SPL is a little too big thats for the dyno queens who just want big numbers. Thankfully the 6 speed gearing helps it too not fall off boost between shifts

Videos dont really do the sound justice need a high quality mic to pick it up.

Sounds strong so lets hope it makes the numbers to back it up

All depends on the driver it aint a free pass haha

[jangles]

and the car setup, but just saying it isnt just a dyno number

[TheGotoGuy]

Worse yet, you could have the "response" setup and be running 13s with 350rwkw......

[nick81xd]

haha awww christian feeling a little bit deflated today are we.

since when have 35r been a responce setup. Never raced with 350kws

Edited December 1, 2011 by nick81xd

[TheGotoGuy]

Are you saying a 35r has poor response and is a bad choice as a street turbo?

And yeah, I am having a down day....

BTW, spl 51r is a great setup for the street, especially if wheelspin from 60-200 on a pair of 295s is your kinda thing.
