I'm not after massive power 340 tops, wanted to keep it fairly standard looking so want to stay with the top mount. Mines a but tatty so was going to get a new upgrade. I've looked at a few American sites but they seem pricey or could I get one off a newer model or are they no better? What would you suggest?

Cheers

uprated top mount typicly are pricey, more pricey than a reasonable front mount. you could put a new age one but there a bit of a cow to fit.

This is how it's done!!

Weirly enough come acorss this today. I'm going to go down this route! But my question is how much better are they? Is it worth doing or getting a new standard one?

I had a standard top mount running 346bhp on my old p1....

No issues with heat soak or anything? I may just get a cover then

My engine with standard top mount is running 341bhp so if in OK condition they work ok.

Heat soak is an issue with any top mount! The main issue is how much they can cool the charged air and obviously the new age intercooler will be better but for you power range the standard one will be fine.

I looked into a newage top mount but it wasn't worth it in the end. Try filling with brake fluid once a new age cooler is fitted. Lol

Unfortunately if you're sticking with a top mount heat soak is inevitable if you're driving it hard for long periods/no flow over the intercooler. A larger top mount intercooler wouldn't prevent this but would be required for higher bhp outputs.

The standard top mount is pretty poor, 3 good pulls and you will see charge temps go beyond 70c. The tmic was thoroughly tested by the late Harvey and these were his findings.

I would move on to a newage sti if you want to stay tmic but bare in mind you will need to mod the undertray and a bigger scoop is preferable to make use of the increased surface area.

It would be easier to go onto a fmic but I understand this is not an option for everyone but would save you quite a bit of hassle

Good points, do you think I'm been daft by wanting to stay tmic? I wanted to keep the car as a p1 see didn't want to do TOO much to it. Obvs a front mount would be so much better and my mate will fit it for me no problem. Am I right in saying a bigger tmic wont give anymore BHP but will restrict bhp if I wanted to get 400bhp or so.....

Thanks

Not at all . ..I've stuck with tmic and gone with a Grimmspeed tmic and undertray from the US . .enginetuner has had good results . ..450+ with that unit . .

Thanks for hat mate ill have a look at the thread now

No probs I haven't had mine fitted yet but hoping for similar results





To help with under bonnet temps I've had exhaust housing, heatsheild and downpipe ceramic coated

Nice, nice! Are you running standard turbo and boost, whats your plan? Mines gone in for work today full service, boost solenoid, upgrated fuel pump and its getting mapped.

Plan is to drop in my forged 2.1 stroker lump with an SC46 and see what she can put out safely

Have you been given any indication of expected power with new shiney bits fitted?

Still I bet the drive home will bring many smiles!

shaun-reef

Just drove her back, so much smoother, can drive it slowly without it guddering now. Boost comes in hard about 4k, I asked for the boost to stay where it was. Antilag been set up much better too pops and bangs like a bitch and just wants to go so all in all very pleased!

Didn't want massive power just wanted it set up safely and right, my guess is around 320bhp but were going to take it to a rolling road when we get chance only out of interest

What are you expecting from your mods? Sounds interesting

Glad all went well and your pleased with the results it makes it all worthwhile

I'm hoping for 430 - 450 but we will have to see . .the build started 2 years and one car ago. Bits have accumulated and then been fitted . . then I've changed my mind on a few things . .initially i looked at a PWR air to water charge cooler instead of a fmic but decided against it and went with Grimmspeed after reading about Enginetuners success with it . .anyway spec of build so far:

EJ207 SCDB with RCM 14mm headstuds
STi 79mm Nitraded Crank
Mahle 2618 pistons and Manley conrods
RCM baffled Sump and plate
V5/6 STi heads with new age coilpack conv
RCM uprated oil Pump
RCM parallel fuel kit
RCM fuel reg
340 lph pump
Id1000 injectors
Grimmspeed Crank pulley
Grimmspeed 8mm phenolic manifold spacers
RCM GT2 Spec headers Ceramic coated
RCM catch can
Scoobyclinic SC46 billet turbo exhaust housing ceramic coated
Grimmspeed 3 port boost solenoid
Grimmspeed TMIC and undertray
All controlled by an Alcatek

Fingers crossed it'll do all right . . .just waiting for a 2 day slot to get it all in and fitted then the pain of running it in :/ . . .watching the trip meter clock up to 999

Id say youd hit 450 fairly easy with that based on stuff ive read and people ive spoke to. It sounds like a nice set up! Did the crack pulley make much difference? I was looking at getting one.

CharlesTuna

I'd like to think so too, thanks

Crank pulley is well made and over 1.5kg lighter than OEM . .it should help with rotational mass . . .every little helps

You want to keep both sides balanced, so would be worth getting a lightened flywheel too
