no its not very hard

bit more involved then you imagine i guess

[bebbinator]

the only hard part is blocking the holes in the engine and drilling new ones

[wolfys_mini]

na really...go read miniboo's project and you will soon see why its MUCH more difficult
your dad may be a mechanic but so? does he have access to to accuratly offset bore your 998 block to accept the head?
also do you understand about the 1098 ISNT the same as a 998 which you seem to be rather confused about...do you even know what piston compression height is?

also...how do you work out its going to be more reliable?

by that reconing all things that were designed for my engine, it should be super reliable...and yet...its not

Hi i have a 1430 with omega pistons crane skatter cam hi lift rockers straight cut gt box limited slip 4 pin diff all running on a single 1.75 su. It produces about 115 to 120 bhp. Even more if i put the 45 webber on it.

Just finished my new build; Its a pre A-plus 998 at +0.030" (havent got a clue what that is, but it wont exactly make any difference!!) With a 12G295 skimmed to suit, not sure on CR but nothing too high. Got a kent 544 profile cam in there aswell (surprisingly not as cammy as i thought it was going to be).

Not sure on power but it goes better than the old 998 did, i'm geussing around the 45-50bhp.

[BadgerBaiter]

Build so far :

1380 AvonBar Turbo Block
Metro Turbo head (will be tarted up and dished out later)
T2 Garrett Turbo
Phase 2 Turbo Cam from Avonbar

Jack Knight Gearbox (need to get drop gears/diff still)

MegaJolt v.4

Need more bits, just not sure which ones yet :/

Need :
CWP, not sure what ratio would be ideal
Drop gears
Vernier timing
Flywheel
X-Pin diff or better
+ more

Really? What sort of output you reckon that engine should be getting?

[Sam Walters]

i know a 276 and a 940 casting head produces 65ish bhp.

and the cam you have is quite similer and the head flows okay too. so around the 55-60 mark.

[miniman92]

A well tuned 998 with a 12g295 and a HIF38 should easily make 60bhp if not more!

very true.

im pretty sure the best head you can put on a small bore is a 295/202 when you have them modified.

the 295 can be modified to flow daft ammounts. the same head to go onto a big bore would require the block pocketing at +20 thou over bore.

Absolutely 100% bog standard! The way I like it!

[Sam Walters]

i dont think i would be able to cope with a standard engine.

ive never had one and i never will.
