Anyone upgraded a standard 3.6?
Discussion
So as not to hijack Rob's thread, please could someone advise me what the best way is to make noteable gains on a 3.6, say 30+ bhp. Is the answer to simply replace it with a RG 4.0 or Power 4.3 or are there "cheaper" mods available that are worth doing.
My 3.6 makes 352bhp with sports exhaust/decat, so what's left to do for considerably less than the price of a replacement engine, airbox/cams/injectors??
I miss the extra power my 4.5 Cerb had, so will be looking to upgrade later this year and would be grateful for the thoughts of anyone who has already gone this route.
cheers

Racing Green Simplex timing chain, with lightened flywheel etc will make it even revier.
ACT airbox with trumpets etc will get more air in, and then decat+ exhaust work to get it back out again.
Joolz is doing some work with his 3.6?
CliveF and (maybe) RND have done work with cams, injectors and a remap - good figures from there.

have a chat with Joolz, rob, he is getting very good numbers from cliff`s 3.6 race car.
Hi Clive, yes i'm keeping an eye on all things Joolz at the moment!I'm just waiting for him to say he's ready to offer a suite of reliable upgrades that give X bhp for X pounds..............then i'll decide what i want to do, it would be easy to dump the 3.6 for more capacity, but it's such a sweet engine it would be criminal to do so.

I agree, I thought the 3.6 in my t350 was a much smoother sweet reving engine compared to the 4lt in the sag, makes me wonder if they were balanced properly when being made, when you talk to poeple with 4.3 and 4.5 rebuilds they say how nice they are as well after being balanced as part of the build program.Pursyluv said:

Yours is the only T model I've ever drove and it felt an amazing car, power delivery was immense and at the same time, rather controllable.

Certainly put a TVR grin on my face.

With my rebuild I haven't gone for bhp but I have tried to go for torque & to bring it in lower down the rev range.Some may argue its not"speed 6" character as its a revvy engine,but lower down power suits my driving style more.Really looking forward to feeling the difference.
Yes i'll be interested in RND's numbers too.A couple of years ago i saw a 4.3 T car post 373bhp on a dyno, assuming the dyno was correct and notwithstanding a smoother power delivery, to me 21 bhp would not be acceptable for say an £8-10k outlay.
I have to say, the 3.6 T350 is mental in the way it delivers it's beans, even if it's not as physically fast in a 0-60 sprint as a Tuscan S/Sag.... It also (as an engine) seems to make a better scream or howl at top revs... Absolutely addictive..
Sag is a great, great car, but not noticeably quicker, unless you have the CR box & 3.73/3.91 diff - which is what makes the 0-60 & 0-100 faster I think.
I'm stuck with a 4.0S engine now in the Sag, but my old T350 had the Power 4.5 upgrade in it with CR box & 3.91 diff - Craig at TrackVRoad told said was absolutely mental !!!!

I'm not sure that's true. There's too much variation in engine outputs from car to car and the difference in power between the 3.6 and 4.0 engines is often marginal and when weight is taken into account the power / weight ratio differences are probably negligible. The faster car 0-60 is more likely to be down to who gets the better start rather than engine size.RedSpike66 said:

Mike, you really should feel how my engine is - revs like a 3.6, but the torque of a 4.3/5. Best of both worlds!
