Im stuck on what to do!!
1- Buy a LET, rebuild and will run eds phase 2 - 270 bhp!
2- SBD tp208 kit and internal work on my engine for 210 bhp!
Mostly A and B road driving, not much dual carriageway and motorway apart from odd trip to southend and car shows and meets!
5-10k miles a year and needs to be reliable, as cars parked for 2-4 weeks at a time and then needed for a weekend etc!!
Let - sounds nice, but hassles of fitting the FMIC, being so cluttered and tight in the engine bay, turbo hassles, traction problems, and cost of buying and rebuilding the LET engine
TB's - sound is amazing, the traction is improoved, i know i have a rebuilt and strong engine but head work and some bottom end work is a must, running mappable ecu with the 208 kit. No worries on FMIC, but cold start problems and fuel economy???
Any help please guys!!

As it's been said, on the road a LET will be faster.
But on a track a TB'd corsa will have the LET's ass handed to it.
Personally for A's +B's I'd go with TB's and a diff.
I's also suggest running emerald since you're near by and Dave Walker is one of The mappers imo.

Yeh i just dont want such a squished engine bay with a LET and the hassles of a new engine etc,
tb's will be about the same as want valves, guides, spings, caps, lifters sorted as well, so its very strong engine!
problem is straights are like 200m at the most around me, i need to drive to the a12,m11 for a dual carriageway and with all the speed cameras i feel i would never really use phase 2 that much!

if your only doin 5-10k a year then u should'nt really be worrying about fuel economy. TB's will look nicer under the hood. but turbo power is better and you'll have the satisfying sound of a dump valve too

Dump Valve sound really doesnt do that much for me!
The boost does!
I need to worry about fuel economy as im a student!!
And them 200 mile round trips to car shows i dont want to be filling up once on the way there and again on the way back!!

dont get me wrong, i love turbos...
Punto GT, Supra, Skyline, Impreza 
but i didnt like the traction with the punto...
fine fine.... 3k...boom, whoooaahaha... even in 4th gear in the wet it was a chump..... and its was only a 1.4 with 190lbft 
for a back road car, TB's
TB's can also be done in good stages
Stage 1:
Fit basic TB kit
(ARP rod bolts, TB's, ECU)
Stage 2:
The head
Get head ported etc
Uprate running gear according to cam profile
fit cams
verniers
uprate pistons if needs be

p.s can't beat a 8k rev limit.
If you're talking about valves springs guides, might aswell stick in solids, to de-tap the engine and some 290deg cat cams, and forged pistons.
Be a little more than 210BHP then too.
turbo's suck the most out of the two anyways

Yeh im waiting for spankee to run his vectra in,
I just think the LET in a corsa in cluttered, ive seen many and theres not much room at all, i like a clean looking engine bay!
3k is the budget i will have really!
so tbs and ecu makes 2k, then 1k on what else??
What the best to go for to get over the 210 bhp within my price range??
We have twin carbs and a 10k rev limiter on the 4age engine in the kit car! Thats damn fun! 50mph in 1st!

save the 1k for 2nd stage and live with 190'ish bhp till your ready....
THEN
solid top end, rebore to 87mm, slipper pistons, 300deg cams, steel crank/rods (if your ACE  ) and a 9k revlimit....
that should see 250bhp.... and a nice hole in the wallet

Adam, i would like 210-215 bhp, i have stainless manifold, rebore,
165 bhp and 163 lb/ft engine as it stands now!
I think the turbo will be more hassle, costs, and reliability than its worth!

....esp when you have a solid base to start with
270 to 280 cams on hydraulic head will be ok (need to uprate springs)....

Forged pocketed pistons - 500
valve spring caps
valve spring seats/platforms
valve springs ( i can give you the part no's if you want)
cams
verniers
BUT all thi sdepends on what you get with the TP208 kit....

look at the 225 kit
its got the pistons and valve gear your after
TP225 Kit
For 2.0 Litre 16V XE & LN Engine
Exhaust manifold type needed to run this with this kit *C-2.0L-XE
The TP225 kit was designed for our customers who liked the TP208 Kit and wished to retain the ultra smooth power delivery without losing any driveability. We managed to achieve this by developing a pair of hydraulic cam profiles with a reasonable increase in duration but high lift to obtain what was needed. Due to the high lift cams the kit includes special springs, caps & spring platforms. We also modify your standard pistons by deepening the standard valve pockets to accommodate the higher lift profiles. If your current pistons are worn they can be replaced with Omega high compression pistons, these already have deeper valve pockets & with their increased compression help to boost torque to over 180 lbft & raise the peak BHP to just under 230.
This kit still allows you to retain the use of the standard Bosch Cream Injectors, Part No.0280 150 744, as fitted to the 2.0L XE engine. As with all our tuning kits, they are designed to be built up by adding on components to your existing TP208 kit. This will enable you to upgrade by adding all the additional components, either in one purchase, or by spreading the cost over several seasons' competition.
When ordering your kit you should specify whether your car is front, rear or mid engine layout. We produce different wiring harnesses to suit each application.
