Radiator to Rocker Cover clearance - VR4 and EVO 1/2/3

[runuts]

Hey all, trying to see if a manifold will fit but need some dimensions as my engine is currently out of the car.

Could anyone with a VR4 and EVO 1/2/3 (or CC with 4G63) measure this distance marked in red in the below pic?

Basically the measurement from the edge of the rocker cover(radiator side), to the edge of the radiator(engine side)

Cheers, much appreciated

dunno if this helps, but my 4G93 gsr is about 20cm's.

175mm mate. If you can make your manifold no wider than 220mm from the head to the widest point of the runner you'll be fine

Cheers for that. Seems that its pretty much the same distance as a VR4. I have full race making me a twin scroll manifold, just needed to check clearances before I gave them the go ahead.

planning to use a evo 4-9 turbo by any chance?

lol.. when E4-9 turbo come with Split pulse T4 1.06 rear housings, maybe

Just get them to jig it all up and check clearances first :wink: You really have to be wary of the following things:

* how tall and how wide it is according to the cyclinder head and radiator
* where your turbo will sit according to the waterpipe.
* where your compressor housing sits according to the engine mount.
* where your external wastegate sits according to your dipstick/power steering pump bracket.
* the angle of which the oil return from the bottom of the cartridge goes into the sump.
* weight of the manifold and whether you can fit a support bracket in somewhere
* how big a merge collector you can fit in without having the turbo sit too low.
* do you have enough clearance to get a tool in to install/remove it :lol:

They're the things we had to consider when making mine up as at first it appears easier than it looks :lol:

The company doing it, is prob one of if not the best. They are cad designing it first. I just needed to confirm the radiator to rocker cover distance, incase we needed to make a few changes.

Its being done by Full-Race in the US.

Full-Race are by far the best in the biz as they are well known in the Honda world for there work. i havnt seen anything that can compare to there work but being the best in the biz comes with the $$$$$$$ as they are pretty expensive but well worth the money spent. ill be keen to see some pics on the finished product runuts.

Cheers, manifold is about 10 weeks off from design to production. I should have the rest of the car back together by then. Will post up pics/details once its all done. The joys of changing parts lol.

Actually mate, the distance is 185mm on a sedan. I measured a mate's GSR with 4G63 in it tonight and his distance is 185mm... My coupe is actually 175mm cause the coupes radiator support panel doesnt stick out as far as the sedans. Hurry up and tell them before they start making it :lol:

Cheers man, its all good, I told them 180, just to give me a bit more clearance. If need be, I'll get a custom radiator to give a bit more clearance. Its going to be tight with the twin wastegates
