ill put a-serious aside on this one mart.

im gunna be useing the t2, how far exactally am i going to have too move the pockets down the bore?

Sorry to bring it to this, but forget A-S, you don;t know me, and I don;t know you, so don;t judge me, otherwise thee will be judged ok - I would of PM'd you, but I can't Bury it


Anyways, what T2?
The R5 GTT are good, but then you have the question on what Manifold you getting?
Also, the reason why you need to sink the pocket further is due to you increasing the lift, not sure how deep, but I'd guess 0.2:1 lower than normal as standard rockers a 1.3:1, so shoving 1.5:1 rockers on, you'll need the valve to lift the extra 0.2:1.

Also, not doing this in spite, but forget the SW5 cam! its a pure N/a Cam, NOT a turbo cam. If you want to build an engine to run N/a for now, go for a Avonbar ph1 Turbo-cam, or the standard Metty turbo cam. This will give you all you need for a realiable 998 turbo.

to be honest, a nicely ported '940 head, with a decent combustion chamber (avonbar or MSPD), along with a decent bottom end, a Avonbar ph1 cam, with a decent manifold and turbo, you'll be putting most "1380's" to shame!!

I'm not trying to teach you how to suck eggs, but in all honesty, I'd (re)build a decent 998 N/a motor, using a SW5 cam, NO hi-lift rockers (no need on a 998), with either a '940 or a '295 head, this will be awesome to run about with, while you build a 998 turbo with a decent spec. Pistons are the biggest problem, as I'd personally, go for Forged, rather than cast, just for the realiablity factor.

Another personal touch I'd do, if you power, and torque, over a revvy engine is get a long stroke crank (1098), this will be loverly on a turbo....

No offence mate, and I'm not trying to put you down either, but I think you are going to get a nasty surprise when you try to insure a car with that spec at 18. Insurance companies hate modifications, especially when you're a young lad. I'd also ring round and see if putting all these fibreglass panels on is going to affect it as well - I'm sure it will. I dunno what all this is about a serious, but Dog's advice is good. Go for a nice N/A motor for a few years, then go for the turbo. If you build a low compression turbo engine and run it n/a it will be a bit poo. At 18 you are still learning how to drive - it doesnt come instantly. I've got a stg1 998 in mine, and it is a great little motor - nippy enough to put a grin on your face, and it will cruise at 70 on the motorway all day.

The other thing - I wouldnt go for the 1.5 rockers either. Turbo's dont like big cams, and even though the sw5 isnt lairy, you will be increasing the valve lift by 1.5 times - which is turning it into something more lumpier. I've heard the N/A MG metty cam is quite a good choice for a turbo?

the insurance company ive chosen appears for minis not to put the price up for insurance for body modifications atall. only the engine that pushes it up, and not excessivly, im gunna have to find out exactally what its going to be tho.

and martin i do know you, and you do know me. but like you said drop it

so dropped.

[minivanman]

Have you spoken to somebody and confirmed that, or is it off the website? If it was me I'd want to know for sure that it wasnt going to affect my insurance in any way.

[Sam Walters]

and i put the whole learning to drive after 18 in a post on this topic somewhere aswell.

[Sam Walters]

nope its from another mini owned whos 17. and hes changed his a great deal and its not changed his insurance premium when hes said to them, however when he changed his engine it went up but not alot he want from a 998 to a 1275 with a fast road cam in it, went up by a 100 or so pounds. i cant remeber who it is on this forum tho.

[Dog]

mildly tuned 1275's ARE cheaper than tuned 998's!!!
I found that one out today too

To insure me on my Van, 998 stg1, modifyed rockers, and alloys... £360 (fully comp)
to insure the same but with a fully worked 1380 - £300!!!!

Work that one out So I;ve said its got the 1380 in there now, says be *yellow human water* arseing about later

[Sam Walters]

i dont understand that, that baffles me!

[Sam Walters]

so 50ish hp vs a mablie 100hp car and its cheaper......WHAT!?

[Dog]

think its because the engine is designed to do the power...
I have no idea at all!
I don't care to be honest, its cheaper
