Hey guys just hoping someone could enlighten me on some troubles with my 33 turbo etc.

I have searched numerous times for answers to the problem but still no luck :|

R33 GTS-T series 2 96

The mods are as follows

Splitfire coilpacks

FMIC

Full 3 inch exhaust with split dump and high flow cat

Apexi pod filter

Stock turbo setup nothing changed at all

Okay so down to the actual problem.

So generally boost kicks in at about 2500-2700rpm on the stock turbo anyway since having the exhaust done as soon as I left the workshop hey presto turbo kicks in at 5500rpm which is ridiculous ! Sure enough the exhaust sounded great but I guess I was in for a tune.

Luckily I had an Apexi power fc already on the way but I can't understand why the turbo kicks in so late when I only had a split dump installed and resonator removed.

Now here's the weird thing.

About 3 weeks later I was boosting it hard on a hill run and after a good flogging the turbo somehow began to work normal again and started spooling at 2500-2700rpm and had been fine ever since except the exhaust is now a lot quieter than it was when I left the shop

I'm just wondering why is it that it somehow went from being ridiculously late and then back to normal again? Wastegate stuck open? And why is the exhaust now seemingly quieter I don't know so send help guys!! Haha

Many thanks in advance

Curtis

thanks for the heads up guys wastegate was definitely sticking....

it got stuck once today on the dyno run :O

So what do you all think?

Revert back to a straight downpipe
Get a dowpipe with a longer intergrated dump?
Bellmouth style dump pipe like Darth Kerjo said

Cheers guys

    • Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners
    • Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.
    • DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
