Default engine rebuild

i was gonna do a det conversion but time money and a serious lack of motivation means it's gonna have to wait till next year!
so new plan is to rebuild 1 of my et lumps! should have det pistons and rods comin next week and already got the following; s13 throttle body, s13 injectors, k&n cone filter, ally fmic, t25, lightened balanced flywheel, s13 exede organic clutch. will be getting walbro 255.
so any1 know other easy and low budget bits i should try and get hold of?
would like a ported head, cam and vernier but funds don't allow!

The exhaust will restrict you but it will work for the time being. The standard centre and especially rear silencer are the biggest restrictions. Changine them will help a great deal alone. Go to 2 1/2" straight through with that setup Or anything upto 3" if you want to allow for future mods. Make one out of universal pipe and an overaxle bend from demontweeks for cheap enough

Other worthwhile mods are an electric fan. Grab one from the scrappy if on a budget. A piggyback ecu for the s13 injectors will be needed.
Other than that you've pretty much got it planned out very well. Glad to see your not neglecting the fuel pump

the piper cam doesnt really give you much power for money spent so i wouldnt really be too concerned/botherd about doing that unless your planning on using a t28rs or t3 etc

Whilst your bottom end is in bits, take your rods/pistons crank and flywheel to ' Burton power ' and have them lightened/balanced. I priced it up ages ago and it was only about 140. They can also hone your block or bore it to suit!

also might be worth seeing if the crankcase girdle from the DET will fit straight on to stiffen the block. take teh longer bearing cap bolts too

cheers for the info chaps! i've already got a silvia engineering twin kenlow set up but forgot to mention it! haven't really got money for lightened and balanced bottom end coz gettin engine gaskets, rings and shells is gonna use most of wot i've got! i was under the impression that the s13 injectors would just run off the standard ecu! wot sort of piggy back system is needed or could i get away with an uprated pressure reg for a while until sorted?

i might be able to get my hands on a t34 roller bearing turbo off a focus rs thats already been fabricated onto an et manifold!
apparently i'll need to "modify" the chassis and engine mount, but i'm thinkin this size turbo wouldn't be very benificial with the basic setup i'm aiming for! i was thinking something more like a t28 off a pulsar or similar might be better!
any input on this would be appreciated

I'd be looking for a T25G from an SR20 S13 or a T28 from an S14. The pulsar turbos have a laggier turbo and you would feel the effect of this.

Its basically a larger T25, but not quite a T28.

My mate has one on his SR20 and its a very good responsive turbo.

The T34 is a bit over the top for the power you're aiming for. Although being a ball bearing unit would mean it would be pretty good for lag considering. Do you know anything about the specs of this turbo? Although its T34, it doesnt always mean its large internally. See if you can find the a/r ratios and wheel trim sizes of this turbo.
