Looking back the cooling on my tubby



I've gone for a lekky pump in the Rex deliberately to try and deal with hotspots, not so much when the engines running but in the few minutes after it's shut down.









Cheers,
Si.

My engine is in the process of a full rebuild and my rev 2 1992 block is being rebored.Upon reading this thread I'm wondering if I made a big mistake not buying a thick walled block.
The engineers never mentioned that it might be worth it.

Has anyone on this site experienced a cracked block on their Rev 2 and if so, what was their set up and what do they think may have caused it?

I'll contact Fensport tomorrow to get a bit more info on this.
llenrub wrote:Sh-t.This is a real worry.
I'm spending serious money to build a good HP vehicle.
Now I'll be too worried to turn the boost up.
Luckily I'm not building it so if it blows, I'll wheel it back to the engineers.
Ive told them I want reasonable HP but without excessively compromising reliabilty.

llenrub wrote:The engine has already been put together so I think its a bit late.The whole project will be finished by the end of this week.
I guess the best I can hope for is to run it well within limits and hope for the best.
llenrub wrote:Another thought is, If the block were to crack am I right to assume that it wouldn't completely destroy the engine and I could use re-use the parts or am I way off.It feels awfull to be thinking like this!

By the way, I'm sure we spoke on the phone recently.I'm the chap having the rebuild done by PTS in Luton.

So with people who may potential have a thin walled block, is it safe to do any modifications to the engine?
Would modifications such as Trd Radiator Cap, Decat Exhaust, AirFilter and Intercooler be fine? But Ecu(Standalone/Piggy Back) and or Boost Controllers be a potential problem causer?
Thanks

llenrub wrote:I asked Paul at PTS if they could test it locally, they said they could but the firm who would do it said that for the cost of shipping and testing I'd be better offf going straight for the liners.Apparently many big HP vehicles go for this option and as long as it is done well the risks are less than a cracked block.
