Hks Cast Dumps For Gtr

[GTR32]

Guys;

just bought these HKS dumps (has HKS cast into them) supposedly for a GTR. no way the exh housing bolt pattern will line up to my N1 turbos although the casting is the right shape ie round on one side and angular on the other etc. if you know them you know what i mean.

was there a 'way back when' change of turbo exh housing flange patterns maybe? as far as i know garrett/HKS/nissan use the same exh housing / dump bolt pattern.

any ideas?

cheers

300ZX maybe?

Definitely not for a GTR

These are what GTR dumps look like..well MINES ones anyway. notice one is longer than the other

omg, those welds are undercut something shocking, and they are supposed to be how good ? not picking on you, just the welds. hehee, the ones that hold the flanges look neat ... but damn

They are to suit a very early version (non ball bearing) of the HKS 25/??. This version had a different exhaust flange, and therefore the terbs were sold complete with manifolds in order to make the terbs a bolt in unit.

Thanks guys

300zx is looking good acording to GCG and BD4s. Garrett has asked me to do some measurements. interestingly the bolt pattern corresponds to 300zx exh housing and part numbers are 065L and 064R which leads me to think it's a v config engine.

Gav it's possible but they could only be off GTR/2JZ/Z32/1JZ/EJ20TT and they all came out in the late 80s/90 and newer. I didn't think the bolt pattern changed for any of these from new ie I think the original bolt patterns remained and these were the ones used by HKS.
