^With a lightweight flywheel, pulleys, advanced timing, CAI, stock clutch kit will do fine, and a header! This would be a nice little GA!

My next mod is about the head, maybe full P&P first, work on the exhaust ports with very carefully and create my N/A cams design 272' / 400". I need good time with the head because this is the horrible part about the GA... For the future mods maybe increase the CR to 12.0:1, create my custom launch control, maybe custom header etc...

Old news i done this about 4 years ago

If you want any parts, or spare cams etc let me know - i have some gear here left!

^What are the specs of the cams you used, vs the OEM cams. It might be old, but it's still good to have on this forum. The GA16 don't get much love over here.

About the GA with all motor setup my friend put 163.2whp on GA16DS, this engine is carburated and come with 93hp at the flywheel. The setup is:
- P&P head. (No flow test)
- Twin 40/40 mikuni carbs.
- Custom regrind cams. (i think is 280' / 350")
- Other engine pistons. (12.0:1 CR) Nissan CA16DE pistons.
- Custom 4-2-1 header, design by a local mechanical.
- 2" exhaust. (He change the exhaust for 2.25" but never dynoed this.)
- 13lbs flywheel.
The problem with this setup is the tune, he have problems with the distributor, he can't tune the timing correct and the carbs not support the same a/f tune...

Yep, 2 years to 8.2k and still alive!!! He have MSD 6a with blaster coil because the OEM vacuum distributor is bad for tune and not work fine for the setup. He have use parts and custom DIY parts, nothing special...
