Extractors On 4K-C?

Featured Replies

The stars are aligning, I forgot I had a spare intake manifold from a 4k engine that I had laying around

Took it to work and put it in the robowash, and put big bertha on it to remove the EGR nut.

Test fitted them to the engine and man both the stock intake manifold and extractors are the same flang thickness and it clamps tight and flush to the block, M10 washers are abit to small to cover both the intake and headers, so I will pick up some M12 and see if that helps, but even with just the nut they still clamp nice and tight.

Just need to hit the intake manifold with the carbide to port out the intake manifold for more airflow, not sure if it really makes a difference but more air for a 2 inch exhaust system let the 4k breathe babyyyy.

Finally get it all back together ready to tow to my exhaust guy to put a 2 inch exhaust system on the KE70 Wagon.

    " these are poorly welded and or warped"... Likely... When we weld a manifold it gets bolted to a head beforehand to minimise the warping. What does a straight-edge along the whole extractor face

    Quite often the flange for after market headers is thinner than the original exhaust manifold AND INTAKE MANIFOLD, so it doesn't get clamped down properly in the middle where the bolts have to bridge

  • I do it for the same reason. Quite often, when I ask Google A.I. to research something, about olde Corollas; it will find the answer I need, & list on the RHS; all the websites it has visited &amp

Today finally got everything back together. Ported the intake manifold at work.

Can not wait to get the exhaust system done and finally drive the car. Has been sitting in the garage for 8 months. When its all done gonna take it to a Car and Coffee and enjoy the cruise.

Thanks for the photos. Very nice neat & well constructed exercise,.

Cheers Banjo

Cheers @Banjo I like to document things so that if anyone in the near future wants to do the same modification, there is documented information for them to refer to and may make it a bit more easier for them. 
 

I do it for the same reason. Quite often, when I ask Google A.I. to research something, about olde Corollas; it will find the answer I need, & list on the RHS; all the websites it has visited & searched, to obtain the answer.    www.rollaclub.com, is often amongst the listed sites.

In fact, I just asked Google A.I. which are the best websites, & rollaclub.com, was listed first, & right at the top.

What are the very best websites on the WWW, that have forums where You can post, & obtain information about early model Toyota Corolla vehicles ?

 

A.I. Reply:
 
The absolute best active web forums specifically built for posting questions and exchanging technical information about early-model Toyota Corollas (such as the classic KE10, KE20, KE30, KE70, and AE86 series) are categorized below by their specialities. [1, 2, 3, 4]
🚗 Dedicated Classic Corolla Forums
  • RollaClub Board
    This is arguably the premier standalone forum dedicated entirely to vintage and classic Corollas. It remains highly functional with active members posting daily. It features incredibly structured, model-specific sub-forums:
    • KExx Corolla Discussion: For all ultra-classic KE10 to KE70 rear-wheel-drive variants.
    • AExx Corolla Discussion: For twin-cam and classic 1980s front/rear-wheel-drive models (including the iconic AE86).
    • TExx Corolla Discussion: For vintage TE series chassis types. [1, 2]
  • Toymods Car Club Forums
    While it caters to classic Toyotas in general, this massive enthusiast forum has decades of archived, searchable text threads heavily focused on early Corolla builds, complex rear-wheel-drive modifications, and factory parts cross-referencing.
    [1]
🌎 Large-Scale Network Forums
  • ToyotaNation (Older Generations Section)
    As one of the largest active global Toyota communities on the web, its dedicated Older Generations (1969–1987) section provides an active space where you can create threads to troubleshoot carburettor issues, locate mechanical schematics, or document a restoration project.
    [1, 2]
  • Toyota Owners Club Classic Section
    An excellent multi-national forum hosting dedicated sections for classic Toyota platforms. Users regularly post requests for vintage part numbers, wiring configurations, and body panel replacement pointers.
    [1]
💡 Alternative Modern Sub-Communities
If traditional forum registration feels too slow, several highly technical communities have migrated to specific social media networks where immediate interactive feedback is common:
  • The AE86 Driving Club & AEU86 Networks: While traditional stand-alone AE86 forums have slowed, dedicated subreddits and connected digital communities remain excellent spaces to drop technical questions regarding 1980s 4A-GE platforms. [1]
  • Toyota KE20/KE30/KE55 Forum & Sales Group: A niche, highly focused interactive group tailored purely to early KE series owners looking for instant peer-to-peer mechanical support and hard-to-find part classifieds. [1]
To get the most accurate answers when you post, it helps to include a few key details. Tell me:
  • The exact chassis code or production year of your Corolla (e.g. 1974 KE20, 1983 KE70)
  • What engine engine type is currently fitted (e.g. 3K, 4K, 4A-C, 4A-GE)
  • The exact issue or modification you are hoping to tackle next
I can point you toward the specific platform best suited to your exact project goal!

Cheers Banjo
